    The UK government has launched a consultation on driverless cars, ahead of on-the-road trials of the vehicles next year. It has now been more than a decade since the prospect of driverless cars on public roads emerged, and prototypes and robotaxi fleets such as Waymo and Cruise replaced human drivers with artificial intelligence (AI).

    But ten years on, and with self-driving cars increasingly common in the US and China, significant obstacles still stand in their way in the UK.

    Despite rapid advances in the tech, other aspects of the driverless journey are still to catch up. Here are five key reasons why autonomous cars are unlikely to take over your local roads any time soon.

    1. Uncertainties around safety

    One of the main benefits of rolling out driverless cars is to increase traffic safety by eliminating driver errors. In the US, the National Highway Traffic Safety Administration reported in 2018 that more than 90% of serious crashes were due to human error. But there is not yet converging evidence to support the idea that AI taking over from human drivers can make roads safer.

    On the other hand, there is evidence that adverse weather conditions, road design, traffic control systems and mixed traffic (that is, human-driven and driverless cars) can degrade the performance of those vehicles. Anomalies in driving patterns and frequent rear-end crashes involving self-driving technologies could indicate the AI algorithms are still far from perfect.

    2. Regulations and legislation falling behind

    Substantial investment in research and development of self-driving technologies has led to a fast-growing and innovative industry. On the other hand, legislation and regulation processes often tend to be slower. These involve multiple stages including drafting, consultation, debate, committee reviews, voting and sometimes judicial review.

    The UK’s Automated Vehicles Act provides a framework for the deployment of driverless vehicles. But the legal codes and mechanisms are still evolving. This is also true of data privacy and cybersecurity.

    For now, there is insufficient legislation governing who can own telematics and vehicle data or how they can be used. Such a widening lag has implications for the mass rollout of driverless cars, and has a direct impact on insuring them.

    3. The insurance industry isn’t ready

    Scarce data, combined with ambiguities in legislation and regulations, means insurance companies face a new set of challenges. These include making sense of where liability lies, developing new insurance models and adapting their premiums as the types of claim evolve.

    In some countries, including the UK, the liability for levels four and five of autonomous driving (very highly automated and fully automated) is shifting from human drivers in conventional vehicles to the manufacturer. Although the insurer pays first, they can recover costs from the tech provider later.

    New risk factors such as cybersecurity further complicate the insurance landscape. Driverless cars are designed to communicate with infrastructure and even other vehicles to decide their routes and avoid collisions. This can open the door to unlawful modifications, hacking or privacy breaches.

    4. Ethical dilemmas

    Heavy traffic and the presence of other road users could lead to scenarios where a crash is inevitable. This would require programmers to design crash severity algorithms that include moral decision-making into autonomous systems. In simple terms, programmers are effectively being asked to write codes that assign value to human lives – an ethical minefield that has yet to be resolved in either academia or industry.

    This echoes the “trolley problem” (a thought experiment about killing one person to save others) but with real-world legal and moral significance. It poses further legal and regulatory questions that could further slow the progress of legislation. Complicating things further is the opaque, black-box nature of AI algorithms.

    5. Changing business models

    Technology developers such as Waymo and Zoox offer only driverless rides and don’t sell vehicles. The recent move by Tesla to launch a robotaxi service in Austin, Texas, also indicates a shift from selling cars to “mobility as a service”, even by car manufacturers.

    In some societies like the US, there is resistance among consumers to relinquishing car ownership due to higher car dependency. This mismatch between the business models of the makers of driverless cars and consumer preferences presents another significant barrier to widespread adoption.

    Even if the technical obstacles are removed, these deeply held sentiments about the nature of mobility may prevent consumers abandoning private vehicles.

    Until the technical, legal, ethical and commercial challenges are addressed, the widespread rollout of driverless vehicles will remain more of a long-term vision than an immediate reality.

  • 4.48 Psychosis revival: the play’s window into a mind on the edge is as brutal as ever

    Source: ForeignAffairs4

    Under bright lights, the audience looks at a bare stage on two planes. Below, a small stage is white and empty, occupied only by a table and two chairs. Above, a huge, slanted mirror reflects a bird’s-eye view of the stage to the audience. Three middle-aged figures enter the stage without looking at each other. One lies down, staring into the mirror. One stands and one sits. For the next 70 minutes, they will never hold one another’s gaze.

    This is the revival of Sarah Kane’s play 4.48 Psychosis. The production takes place 25 years after the original work, bringing the original cast and creative team back to the Royal Court where the play was first staged – now transferred to The Other Place, a small theatre run by the Royal Shakespeare Company.

    It replicates the staging of the original with precision. The same faces are on the same set, making the same gestures. Even the projections of the street outside show cars from the 1990s. And yet, because this is theatre, there are inevitable differences.

    The play is a revival and a commemoration. Kane wrote 4.48 Psychosis in the year leading up to her death by suicide in 1999 and completed it during her final stay in a psychiatric hospital. It stages the experience of a suicidal and psychotic mind breaking down.

    About a week after sending the play to her agent, Kane ended her own life. A year later, the original production was staged at the Royal Court, directed by her long-term collaborator James Macdonald and starring three young actors: Daniel Evans, Madeleine Potter and Jo McInnes. All three have returned for this revival.

    4.48 Psychosis is a highly experimental play. It contains dialogue between doctor and patient, poetry, seemingly psychotic speech, lists and quotations from literature and medical documents. In her aims for the play, Kane was both very open and very specific. She described the play in an interview at Royal Holloway University as an attempt to stage the experience of a mind breaking down:

    I’m writing a play called 4:48 Psychosis … It’s about a psychotic breakdown and what happens in a person’s mind when the barriers which distinguish between reality and different forms of imagination completely disappear … you no longer know where you stop and the world starts.

    What’s more, through an experimental style, Kane hoped to make her audience experience some of the distress experienced by the mental collapse being staged. She described this as “making form and content one”.

    How this strange work was to be staged was to be left up to future creatives. She didn’t specify how many actors should perform the work, or provide references to their age or gender. Kane believed that as a playwright, her job was to write the work, and then let directors figure it out.

    The result was that the first performance split the experience of breakdown across three actors. At times, they take on more specific roles such as a patient, a doctor, and a lover or bystander. At others, they all seem to occupy a shared mental reverie.

    Since the original production, 4.48 Psychosis has been staged in multiple ways around the world. French actor Isabelle Huppert performed the first French production largely as a monologue in 2005, with occasional lines delivered by Gérard Watkins as a psychiatrist. Recently in the UK it has been transformed into a successful opera in which a six-person ensemble and full orchestra performed the play’s “hive mind”, and has been performed in a plastic box in British Sign Language.

    When it was first performed in 2000, a year after Kane’s death, the play left a profound impression on its audiences. It was arguably one of the most brutal, head-on representations of mental illness that had ever been seen in British theatre. Reviews from that first production discuss anxieties about whether the play should be viewed as a “suicide note” – a disturbingly “real” reference to Kane’s death.

    Today, such anxieties may seem less relevant. After all, over two decades have passed since Kane’s death, and we are in a very different world when it comes to how we view disclosure of personal struggle. In a culture of mental health awareness campaigns and social media oversharing, the closeness of Kane’s suffering to her work seems less scandalous, and perhaps less unsettling.

    At times, this revival feels a bit more like a repetition, or archival reconstruction than a fresh performance. There are moments that feel dated – for example, the use of pixelated projections.

    The most compelling moments were where something original was introduced due to the more advanced ages of the actors. In my experience, the play is typically performed by a younger cast, as a rageful, energetic cry of despair. It hits differently with a cast in their fifties.

    Madeleine Potter’s resigned, ironic complaints about being mistreated by “Dr This and Dr That” gave the impression of a woman with a lifetime’s experience of inadequate mental health services. And Jo McInnes’s desperate monologue about lost love could be referencing an estranged or dead child, as much as a lover.

    These moments inserted something new into Kane’s iconic last work and underlined that mental suffering is far from being the privilege of the young. More of a slow burn than an explosive cry of anger, this return to 4.48 Psychosis explores mental torment that can persist over a lifetime, revealing it to be as relevant as ever.

    4.48 Psychosis is at The Other Place until July 27.

  • Counting the climate costs of abandoned shopping trolleys

    Source: ForeignAffairs4

    Source: The Conversation – UK – By Neill Raath, Assistant Professor of Sustainable Materials and Manufacturing, University of Warwick

    Despite the steady growth of online shopping, a majority of the UK public still prefers to buy groceries at the supermarket.

    Shopping trolleys can help us lug our purchases back to the car, but some shoppers are evidently taking them further afield. In 2017, 520,000 trolleys were reported as abandoned in the UK. Sunderland in north-east England alone reported 30,000 abandoned trolleys between 2020 and 2022. Likewise, 550 trolleys were collected in a single day in western Sydney, Australia.

    Supermarkets employ a range of methods to stop trolleys leaving their premises, including coin slots, vertical bars (to stop trolleys leaving the shop floor), wheel-locking mechanisms and car park wardens. Despite these efforts, abandoned trolleys still blight the landscape and need to be collected.

    Many supermarkets use commercial collection services, such as Wanzl TrolleyWise or TMS Collex. These companies typically use diesel vans to survey suburban areas, collect trolleys and return them to supermarkets. They also offer to refurbish weathered or damaged trolleys, sometimes by applying a zinc-based coating to protect against corrosion – a process known as regalvanisation.

    We are researchers at the University of Warwick who wanted to understand the environmental impact of trolley abandonment. So, we set out to investigate it.

    Collecting versus manufacturing

    How does the environmental impact of using vans to rescue abandoned trolleys compare with losing these trolleys to excessive damage or corrosion and having to make new ones?

    Our study used a standardised methodology known as life-cycle assessment to analyse the potential environmental impact of collecting and handling abandoned shopping trolleys within an area of Coventry, a city in the English West Midlands, which includes our university campus.

    We spoke to trolley suppliers, who told us trolleys used at the supermarket in Coventry were most likely made in Spain. This was incorporated into our model.

    Neill Raath

    Through conversations with our university’s estates department and commercial collection services, we established that approximately 30 trolleys were collected a week on average in the area surrounding the Tesco supermarket in the Cannon Park shopping centre.

    Our model assumed that a bulk transport of 50 trolleys is sent twice each year to be refurbished, in a round trip of 220km between Coventry and a refurbishment facility based in the UK that was noted on stickers placed on refurbished trolleys.

    Vans collecting 520,000 abandoned trolleys in a year could emit the equivalent of 343 tonnes of CO₂ (the annual equivalent of driving 80 petrol cars). If we imagine that 10% of these 520,000 trolleys have been left outside too long and need to be regalvanised then the total global warming impact increases by 90% to the equivalent of 652 tonnes CO₂ (roughly the same as 152 petrol cars being driven for one year).

    This is quite a surprising increase for such a small number of trolleys. It suggests that the real problem lies with the environmental impact of manufacturing.

    Most of the emissions can be avoided

    We found that one trolley would have to be collected 93 times by a diesel van to have the same environmental impact as manufacturing a new one.

    Our results showed that the emissions incurred during the diesel van collection phase were only 1% of the manufacturing impact, and the regalvanisation stage was only 8%. We might wonder whether switching to electrically powered collection vans might help. While the emissions would be reduced, the impact of using diesel vans is still minuscule compared to that of making new trolleys.

    We found that the highest environmental impact stemmed from manufacturing, which was mainly attributed to making and replacing the steel frame of the trolley.

    These results reinforce the benefits of following the circular-economy principle of keeping trolleys in use for as long as possible, and avoiding manufacturing to replace abandoned ones.

    Would anything change if we switched to plastic trolleys? Other researchers have investigated the effect of changing trolley materials and have found that trolleys made of polymers have many benefits compared with steel: they use less material, are less dense (a benefit for collection vans that emit less by driving around lighter products) and do not require protective coatings, which themselves have an environmental impact.

    Blast furnaces at conventional steelworks are very carbon-intensive.

    However, if these polymer trolleys were to be sent to landfill (or left to deteriorate in the environment), they could release carcinogenic chemicals, as well as microplastics, as they break down. This leads us back to the importance of keeping products in use.

    Abandoning trolleys is bad for the environment, with a potential global warming impact equivalent to 0.69 kg CO₂ for collecting one trolley and returning it to a supermarket. If we multiply this by the potential 520,000 abandoned trolleys a year, this figure becomes quite big.

    Preventing trolley abandonment should be a priority not just for supermarkets, but for the general public as well. However, once a trolley is abandoned, it is far better to collect and refurbish it than to let it fall out of use and manufacture a new one, as 92–99% of the environmental impact can be avoided.

    While it is unlikely that we can ever stop trolleys being abandoned, we hope that next time people see a trolley in an alley or park bush, the potential environmental impact of losing this trolley to service would be apparent.

  • Physically restricting mental health patients can often harm them – my new study suggests compassion could change that

    Source: ForeignAffairs4

    Source: The Conversation – UK – By Daniel Lawrence, Senior Lecturer in Forensic Psychology, Cardiff Metropolitan University

    Restrictive practices in mental health settings – such as physical restraint and seclusion – are meant to be a last resort, used only when patients pose a risk to themselves or others.

    In 2021 and 2022 alone, NHS England reported that 6,600 mental health patients were subjected to physical restraint, and 4,500 to seclusion. Figures such as these have led numerous experts and policymakers to conclude that restrictive practices are overused in mental health inpatient settings.

    The consequences can be devastating. Restrictive practices are associated with trauma, worsening mental health, and even death. For decades, clinicians, researchers and policymakers have called for their reduction. Progress, however, remains painfully slow.

    For the past five years, I have been researching the use of restrictive practices in mental health services and exploring how to reduce them. My new research demonstrates the importance of using compassion to support staff to promote the dignity and wellbeing of patients as a priority.

    Restrictive practices have a long history that predates the development of asylums and psychiatry as a medical discipline. The use of legislation to detain people on the basis of their mental health in England, for example, dates back to at least the 14th century. Early examples of restrictive practices included patients being bound and beaten with rods in order to “restore sanity”.

    During the first three decades of the 19th century, mechanical restraints such as straitjackets, chains and restraint chairs and confining patients in locked rooms were widely accepted methods of controlling violent people in British asylums. But in the 1830s, some clinicians recognised the moral and ethical problems with using such practices, and a campaign began to abolish them.

    The UN has long recognised restrictive practices in mental healthcare as a human rights issue. In 2008, the UN’s special rapporteur on torture stated that methods such as solitary confinement violate articles 14 and 15 of the Convention on the Rights of Persons with Disabilities, which protect against arbitrary detention and cruel, inhuman or degrading treatment.

    This stance was reaffirmed in 2021 when the UN declared that restrictive practices breach the fundamental rights of patients. This underscores the urgent need for reform in mental healthcare systems worldwide.

    Harmful effect

    Research shows that restrictive practices may not only harm patients but contradict the goals of mental healthcare. Many mental health problems stem from traumatic experiences that leave people feeling powerless, unsafe and distressed. Using methods that reinforce these feelings can worsen the very issues services aim to address.

    In extreme incidents, people have died as a result of restrictive practices use.

    In my research, I have developed a theoretical model identifying core factors that perpetuate the use of restrictive practices in mental health services. These include the emotional challenges faced by staff working in high-stress environments, and how these challenges influence their decision-making.

    Mental health wards can be highly stressful environments, with frequent incidents of aggression. In such settings, staff can often feel anxious and hyper-vigilant, which can make it harder for them to respond to patients with compassion.

    Research shows that threat-based emotions like fear and anger are linked to a greater likelihood of using restrictive measures. So, this cycle perpetuates the use of these harmful practices.

    Compassion may hold the key

    Using restrictive practices to control or remove people who are perceived as a threat can provide staff with a sense of immediate safety, which may inadvertently reinforce their use. To address this, I wanted to explore whether supporting staff to manage their emotions more effectively could reduce their reliance on restrictive practices, and foster a more compassionate approach to care.

    As part of my research, I introduced compassion-focused support groups for staff in several forensic mental health wards, advocating for a more empathetic and patient-centred approach. These groups tried to equip participants with skills to better manage challenging emotional experiences while fostering greater compassion for both themselves and the people in their care.

    The aim was to help staff cultivate an inner sense of safety, reducing their reliance on restrictive practices as a means of managing their own feelings of threat. This intervention was encouraging, leading to reductions in the use of restrictive practices in some conditions – demonstrating the potential of using compassionate care for these purposes.

    My study was the first of its kind – bur these initial results highlight the need for further research into how the emotional management of staff influences care decisions. The journey toward change is slow, but it is possible. Compassion may hold the key to addressing a deeply entrenched issue that has shaped the treatment of mental health patients for centuries.

  • Grandparent care: women from poorer backgrounds help out most with childcare

    Source: ForeignAffairs4

    Source: The Conversation – UK – By Giorgio Di Gessa, Lecturer in Data Science, UCL

    Grandparents play a pivotal role in family life. They are often a vital part of the childcare puzzle, stepping in to look after their grandchildren while parents are at work or busy. And there’s a lot of grandparent care taking place.

    In England, around half of all grandparents provide care for their grandchildren when the parents are not around. And the percentage of grandparents providing care is even higher when they have grandchildren aged 16 and under, who are more likely to require supervision, care, and support from an adult when the parents are busy at work or unavailable. In this case, 66% of grandparents help out.

    I used data from the English Longitudinal Study of Ageing, to analyse the caring roles of over 5,000 grandparents. I used data collected in 2016-17 to assess how often grandparents looked after their grandchildren, the activities they did with them, and why they helped out. I also discovered that there are clear gender and socioeconomic patterns. Further analysis of data from 2018-19 showed that providing care as a grandparent can affect wellbeing.

    I found that in England, among grandparents who looked after grandchildren, 45% of grandparents spent at least one day a week looking after their young grandchildren. They did so consistently throughout the year, with 8% doing so almost daily. Approximately one in three grandparents provided care to their grandchildren during school holidays.

    Around 25% of grandparents who looked after their grandchildren were still working. Most grandparents reported having overall good physical health.

    And most grandparents who cared for their grandchildren also lived relatively close to them – less than half an hour away from their closest grandchild – and had at least one grandchild aged under six years old.

    Most of the grandparents in the study who cared for grandchildren – 80% – mentioned that they played or took part in leisure activities with their grandchildren. Around half said that they frequently cooked for them and helped with picking them up and dropping them off from schools and nurseries. And although it was less common, grandparents also helped with homework and taking care of their grandchildren when they were not feeling well.

    About three grandparents in four (76%) said that their motivation for helping out was to give their grandchildren’s parents some time out from childcare responsibilities. A similar percentage – 70% – said they wanted to provide some economic support, either by offering financial assistance or by allowing parents to go to work.

    Just over half of grandparents (52%) said that being able to provide emotional support was what drove their motivation to provide grandchild care: they wanted to feel engaged with young people and help their grandchildren develop. But 17% say that they felt obliged to help out, and found it difficult to refuse.

    The grandmother’s role

    But while we tend to talk about “grandparents” as a group, grandmothers and grandfathers often experience and approach caregiving in distinctly different ways.

    In particular, when examining the specific activities undertaken with their grandchildren, there are clear gender distinctions. I found that grandmothers were more likely than grandfathers to engage in hands-on tasks: preparing meals, helping with homework, caring for grandchildren when they are sick, and doing school pick-ups.

    Grandfathers were less likely to do hands-on caring activities, such as school pickups.

    Grandfathers, while also involved, tended to participate less in these activities. This is the case even among grandparent couples who lived together and jointly cared for their grandchildren.

    The role of wealth

    The extent and nature of grandparental care is also closely linked to grandparents’ socioeconomic status. For example, grandparents with fewer financial resources tended to offer childcare more regularly than their wealthier counterparts.

    Socioeconomic disparities also shape the nature of caregiving tasks. Less affluent grandparents were more likely to engage in hands-on activities, such as cooking meals and taking their grandchildren to and from school. In contrast, grandparents with more education were more likely than those with less education to help with homework frequently.

    The reasons for providing care also varied according to grandparents’ socioeconomic status. Grandparents with greater financial resources and higher levels of education were more likely to report providing childcare to help parents manage work and other responsibilities, as well as to offer emotional support to their grandchildren. Conversely, those with fewer financial resources were more likely to feel obliged to help or to struggle to refuse caregiving duties.

    Grandparent wellbeing

    What grandparents do with their grandchildren and why they have an active role in caring for them can also affect their wellbeing in complex ways. Grandparents who often took part in fun or enriching activities with their grandchildren, such as leisure activities or helping with homework, tended to report higher wellbeing compared to their peers who did not look after grandchildren.

    However, grandparents who cared for their grandchildren when they were sick or who had them stay overnight without parents tended to report, over time, lower wellbeing.

    Motivations also matter for grandparents’ wellbeing. Grandparents had a higher quality of life if they cared for their grandchildren because they wanted to help them develop as people, or to feel engaged with young people. However, grandparents who felt obliged to help, perhaps due to family pressure or lack of alternatives, experienced lower wellbeing.

    In short, these findings remind us that behind the broad label of “grandparenting” lies a diverse world of individuals whose involvement in caring for grandchildren – how often they care, what they do, and why – is closely linked to and varies with gender norms and socioeconomic status.

    Also, the meaning behind grandparenting and the type of interactions shared with grandchildren seems to matter for grandparents’ wellbeing. Overall, these insights suggest that these caring responsibilities may contribute to the reinforcement or even deepening of existing gender, socioeconomic and health inequalities among older adults.

  • MIL-OSI Analysis: Gene editing technology could be used to save species on the brink of extinction

    Source: The Conversation – UK – By Cock Van Oosterhout, Professor of Evolutionary Genetics, University of East Anglia

    Earth’s biodiversity is in crisis. An imminent “sixth mass extinction” threatens beloved and important wildlife. It also threatens to reduce the amount of genetic diversity – or variation – within species.

    This variation in genes within a species is crucial for their ability to adapt to changes in the environment or resist diseases. Genetic variation is therefore crucial for species’ long term survival.

    Traditional conservation efforts – such as protected areas, measures to prevent poaching, and captive breeding – remain essential to prevent extinction. But even when these measures succeed in boosting population numbers, they cannot recover genetic diversity that has already been lost. The loss of a unique gene variant can take thousands of years of evolution before it is recovered by a lucky mutation.

    In a new paper in Nature Reviews Biodiversity, an international team of geneticists and wildlife biologists argues that the survival of some species will depend on gene editing, along with more traditional conservation actions. Using these advanced genetic tools, like those already revolutionising agriculture and medicine, can give endangered species a boost by adding genetic diversity that isn’t there.

    Genetic engineering is not new. Plant breeders have used it for decades to develop crops with traits to boost disease resistance and drought tolerance. Around 13.5% of the world’s arable land grows genetically modified crops. Gene-editing tools such as Crispr are also being used in “de-extinction” projects that aim to recreate extinct animals.

    The Dallas-based company Colossal Laboratory & Biosciences has attracted headlines for its efforts to bring back the woolly mammoth, dodo and dire wolf. In de-extinction, the DNA of a living relative species is edited (changed) to approximate the extinct species’ most charismatic traits.

    For example, to “resurrect” a woolly mammoth, Colossal’s researchers plan to splice mammoth genes (recovered from ancient remains) into the genome of the Asian elephant to produce a cold-hardy, hairy elephant-mammoth hybrid. Colossal recently engineered grey wolf pups with 20 gene edits from the extinct dire wolf’s DNA.

    Colossal edited grey wolves to have traits from extinct dire wolves.
    Colossal

    The “Jurassic Park”-style revival of long-gone creatures has attracted considerable attention and funding, which has accelerated the development of genome engineering techniques. These same genome editing tools can be used for conservation of existing and endangered species. If we can edit a mouse to have mammoth hair, or edit a wolf to resemble a dire wolf, why not edit an endangered bird’s genome to make it more resilient to disease and climate change?

    Museum specimens

    Using DNA from historical specimens, scientists can identify important genetic variants that a species has lost. Many museums hold century-old skins, bones, or seeds – a genomic time capsule of past diversity. With genome editing, it is possible to reintroduce these lost variants into the wild gene pool.

    By restoring genetic variation, species can be fortified against emerging diseases and environmental change. A sharp decline in population numbers is called a “bottleneck”. During a bottleneck, inbreeding and genetic drift lead to the random loss of genetic diversity. Harmful mutations can also increase in frequency. Such “genomic erosion” compromises the health of individuals and can make populations more prone to extinction.

    If we can pinpoint a particularly damaging mutation that has become widespread in the population or a variant that has been lost, we could replace it in a few individuals using gene editing. Aided by natural selection, the healthy variant would gradually spread in the population.

    If a threatened species lacks genes that it desperately needs to survive new conditions, why not borrow them from a close relative that already has those traits? Known as facilitated adaptation, this could help wildlife cope with threats such as climate change.

    In agriculture, such cross-species gene transfers are routine. Tomatoes have been engineered with a mustard plant gene to tolerate cold, and chestnut trees got a wheat gene for disease resistance. There is no reason why such techniques cannot be expanded to animals.

    These genetic interventions can complement, but never replace traditional conservation measures. Habitat protection, control of invasive predators, captive breeding programmes, and other on-the-ground action remain absolutely necessary. Importantly, gene editing only makes sense if the target population has recovered in numbers enough (often through conservation), to allow natural selection to do its job.

    Measuring the risk of extinction

    Gene-edited animals or plants wouldn’t have a chance if released into a barren habitat or a poaching hotspot. Genomic tools can give an extra edge to species that are already being saved from immediate threats, equipping them for adaptive evolution in the future.

    Climate zones are shifting, new diseases are spreading, and once-isolated populations are cut off in small fragments of habitat. Without intervention, even intensive habitat management might not prevent a wave of extinctions.

    However, a strategy of gene editing also comes with significant risks and unknowns. One technical concern is off-target effects – Crispr and other gene-editing techniques might make unintended DNA changes in addition to the intended edit. In other words, you attempt to insert a disease-resistance gene, but accidentally disrupt another gene in the process. Similarly, a gene may have more than one function, which is known as pleiotropy.

    Especially in less-well studied species, we may not be aware of all those functions or pleiotropic effects. Regulatory inertia and public scepticism may also present big obstacles – these issues have historically limited the rollout of genetically modified (GM) organisms, particularly in agriculture.

    There are also evolutionary and ecological uncertainties. A deliberate gene edit might have knock-on effects on how the species evolves over time. For instance, if one individual is given a highly beneficial gene that spreads rapidly, it could replace all the other gene variants at that location in the genome (the full complement of DNA in the organism’s cell). This is known as a “selective sweep”, and it inadvertently reduces the genetic diversity in that region of the genome.

    Some critics argue that the narrative of a genetic quick fix could distract from the root causes of biodiversity loss. If people believe we can simply “edit” a species to save it, will that undermine the urgency to protect habitats or cut carbon emissions? Portraying extinction as reversible might seed false hope and reduce the motivation for tough environmental action.

    Conservation efforts, strong environmental policies and legal protections remain indispensable. So do habitat restoration, climate action and reducing the impact made on the environment by humans.

    Nevertheless, genome engineering is a new tool in the conservation toolbox. It’s one that –given the right assistance and environmental encouragement – can help save species from extinction.

  • MIL-OSI Analysis: Counting the climate costs of abandoned shopping trolleys

    Source: The Conversation – UK – By Neill Raath, Assistant Professor of Sustainable Materials and Manufacturing, University of Warwick

    Despite the steady growth of online shopping, a majority of the UK public still prefers to buy groceries at the supermarket.

    Shopping trolleys can help us lug our purchases back to the car, but some shoppers are evidently taking them further afield. In 2017, 520,000 trolleys were reported as abandoned in the UK. Sunderland in north-east England alone reported 30,000 abandoned trolleys between 2020 and 2022. Likewise, 550 trolleys were collected in a single day in western Sydney, Australia.

    Supermarkets employ a range of methods to stop trolleys leaving their premises, including coin slots, vertical bars (to stop trolleys leaving the shop floor), wheel-locking mechanisms and car park wardens. Despite these efforts, abandoned trolleys still blight the landscape and need to be collected.

    Many supermarkets use commercial collection services, such as Wanzl TrolleyWise or TMS Collex. These companies typically use diesel vans to survey suburban areas, collect trolleys and return them to supermarkets. They also offer to refurbish weathered or damaged trolleys, sometimes by applying a zinc-based coating to protect against corrosion – a process known as regalvanisation.

    We are researchers at the University of Warwick who wanted to understand the environmental impact of trolley abandonment. So, we set out to investigate it.

    Collecting versus manufacturing

    How does the environmental impact of using vans to rescue abandoned trolleys compare with losing these trolleys to excessive damage or corrosion and having to make new ones?

    Our study used a standardised methodology known as life-cycle assessment to analyse the potential environmental impact of collecting and handling abandoned shopping trolleys within an area of Coventry, a city in the English West Midlands, which includes our university campus.

    We spoke to trolley suppliers, who told us trolleys used at the supermarket in Coventry were most likely made in Spain. This was incorporated into our model.

    Neill Raath

    Through conversations with our university’s estates department and commercial collection services, we established that approximately 30 trolleys were collected a week on average in the area surrounding the Tesco supermarket in the Cannon Park shopping centre.

    Our model assumed that a bulk transport of 50 trolleys is sent twice each year to be refurbished, in a round trip of 220km between Coventry and a refurbishment facility based in the UK that was noted on stickers placed on refurbished trolleys.

    Vans collecting 520,000 abandoned trolleys in a year could emit the equivalent of 343 tonnes of CO₂ (the annual equivalent of driving 80 petrol cars). If we imagine that 10% of these 520,000 trolleys have been left outside too long and need to be regalvanised then the total global warming impact increases by 90% to the equivalent of 652 tonnes CO₂ (roughly the same as 152 petrol cars being driven for one year).

    This is quite a surprising increase for such a small number of trolleys. It suggests that the real problem lies with the environmental impact of manufacturing.

    Most of the emissions can be avoided

    We found that one trolley would have to be collected 93 times by a diesel van to have the same environmental impact as manufacturing a new one.

    Our results showed that the emissions incurred during the diesel van collection phase were only 1% of the manufacturing impact, and the regalvanisation stage was only 8%. We might wonder whether switching to electrically powered collection vans might help. While the emissions would be reduced, the impact of using diesel vans is still minuscule compared to that of making new trolleys.

    We found that the highest environmental impact stemmed from manufacturing, which was mainly attributed to making and replacing the steel frame of the trolley.

    These results reinforce the benefits of following the circular-economy principle of keeping trolleys in use for as long as possible, and avoiding manufacturing to replace abandoned ones.

    Would anything change if we switched to plastic trolleys? Other researchers have investigated the effect of changing trolley materials and have found that trolleys made of polymers have many benefits compared with steel: they use less material, are less dense (a benefit for collection vans that emit less by driving around lighter products) and do not require protective coatings, which themselves have an environmental impact.

    Blast furnaces at conventional steelworks are very carbon-intensive.

    However, if these polymer trolleys were to be sent to landfill (or left to deteriorate in the environment), they could release carcinogenic chemicals, as well as microplastics, as they break down. This leads us back to the importance of keeping products in use.

    Abandoning trolleys is bad for the environment, with a potential global warming impact equivalent to 0.69 kg CO₂ for collecting one trolley and returning it to a supermarket. If we multiply this by the potential 520,000 abandoned trolleys a year, this figure becomes quite big.

    Preventing trolley abandonment should be a priority not just for supermarkets, but for the general public as well. However, once a trolley is abandoned, it is far better to collect and refurbish it than to let it fall out of use and manufacture a new one, as 92–99% of the environmental impact can be avoided.

    While it is unlikely that we can ever stop trolleys being abandoned, we hope that next time people see a trolley in an alley or park bush, the potential environmental impact of losing this trolley to service would be apparent.

    MIL OSI Analysis

  • MIL-OSI Analysis: Physically restricting mental health patients can often harm them – my new study suggests compassion could change that

    Source: The Conversation – UK – By Daniel Lawrence, Senior Lecturer in Forensic Psychology, Cardiff Metropolitan University

    Restrictive practices in mental health settings – such as physical restraint and seclusion – are meant to be a last resort, used only when patients pose a risk to themselves or others.

    In 2021 and 2022 alone, NHS England reported that 6,600 mental health patients were subjected to physical restraint, and 4,500 to seclusion. Figures such as these have led numerous experts and policymakers to conclude that restrictive practices are overused in mental health inpatient settings.

    The consequences can be devastating. Restrictive practices are associated with trauma, worsening mental health, and even death. For decades, clinicians, researchers and policymakers have called for their reduction. Progress, however, remains painfully slow.

    For the past five years, I have been researching the use of restrictive practices in mental health services and exploring how to reduce them. My new research demonstrates the importance of using compassion to support staff to promote the dignity and wellbeing of patients as a priority.

    Restrictive practices have a long history that predates the development of asylums and psychiatry as a medical discipline. The use of legislation to detain people on the basis of their mental health in England, for example, dates back to at least the 14th century. Early examples of restrictive practices included patients being bound and beaten with rods in order to “restore sanity”.

    During the first three decades of the 19th century, mechanical restraints such as straitjackets, chains and restraint chairs and confining patients in locked rooms were widely accepted methods of controlling violent people in British asylums. But in the 1830s, some clinicians recognised the moral and ethical problems with using such practices, and a campaign began to abolish them.

    The UN has long recognised restrictive practices in mental healthcare as a human rights issue. In 2008, the UN’s special rapporteur on torture stated that methods such as solitary confinement violate articles 14 and 15 of the Convention on the Rights of Persons with Disabilities, which protect against arbitrary detention and cruel, inhuman or degrading treatment.

    This stance was reaffirmed in 2021 when the UN declared that restrictive practices breach the fundamental rights of patients. This underscores the urgent need for reform in mental healthcare systems worldwide.

    Harmful effect

    Research shows that restrictive practices may not only harm patients but contradict the goals of mental healthcare. Many mental health problems stem from traumatic experiences that leave people feeling powerless, unsafe and distressed. Using methods that reinforce these feelings can worsen the very issues services aim to address.

    In extreme incidents, people have died as a result of restrictive practices use.

    In my research, I have developed a theoretical model identifying core factors that perpetuate the use of restrictive practices in mental health services. These include the emotional challenges faced by staff working in high-stress environments, and how these challenges influence their decision-making.

    Mental health wards can be highly stressful environments, with frequent incidents of aggression. In such settings, staff can often feel anxious and hyper-vigilant, which can make it harder for them to respond to patients with compassion.

    Research shows that threat-based emotions like fear and anger are linked to a greater likelihood of using restrictive measures. So, this cycle perpetuates the use of these harmful practices.

    Compassion may hold the key

    Using restrictive practices to control or remove people who are perceived as a threat can provide staff with a sense of immediate safety, which may inadvertently reinforce their use. To address this, I wanted to explore whether supporting staff to manage their emotions more effectively could reduce their reliance on restrictive practices, and foster a more compassionate approach to care.

    As part of my research, I introduced compassion-focused support groups for staff in several forensic mental health wards, advocating for a more empathetic and patient-centred approach. These groups tried to equip participants with skills to better manage challenging emotional experiences while fostering greater compassion for both themselves and the people in their care.

    The aim was to help staff cultivate an inner sense of safety, reducing their reliance on restrictive practices as a means of managing their own feelings of threat. This intervention was encouraging, leading to reductions in the use of restrictive practices in some conditions – demonstrating the potential of using compassionate care for these purposes.

    My study was the first of its kind – bur these initial results highlight the need for further research into how the emotional management of staff influences care decisions. The journey toward change is slow, but it is possible. Compassion may hold the key to addressing a deeply entrenched issue that has shaped the treatment of mental health patients for centuries.

    MIL OSI Analysis

  • MIL-OSI Analysis: Grandparent care: women from poorer backgrounds help out most with childcare

    Source: The Conversation – UK – By Giorgio Di Gessa, Lecturer in Data Science, UCL

    Grandparents play a pivotal role in family life. They are often a vital part of the childcare puzzle, stepping in to look after their grandchildren while parents are at work or busy. And there’s a lot of grandparent care taking place.

    In England, around half of all grandparents provide care for their grandchildren when the parents are not around. And the percentage of grandparents providing care is even higher when they have grandchildren aged 16 and under, who are more likely to require supervision, care, and support from an adult when the parents are busy at work or unavailable. In this case, 66% of grandparents help out.

    I used data from the English Longitudinal Study of Ageing, to analyse the caring roles of over 5,000 grandparents. I used data collected in 2016-17 to assess how often grandparents looked after their grandchildren, the activities they did with them, and why they helped out. I also discovered that there are clear gender and socioeconomic patterns. Further analysis of data from 2018-19 showed that providing care as a grandparent can affect wellbeing.

    I found that in England, among grandparents who looked after grandchildren, 45% of grandparents spent at least one day a week looking after their young grandchildren. They did so consistently throughout the year, with 8% doing so almost daily. Approximately one in three grandparents provided care to their grandchildren during school holidays.

    Around 25% of grandparents who looked after their grandchildren were still working. Most grandparents reported having overall good physical health.

    And most grandparents who cared for their grandchildren also lived relatively close to them – less than half an hour away from their closest grandchild – and had at least one grandchild aged under six years old.

    Most of the grandparents in the study who cared for grandchildren – 80% – mentioned that they played or took part in leisure activities with their grandchildren. Around half said that they frequently cooked for them and helped with picking them up and dropping them off from schools and nurseries. And although it was less common, grandparents also helped with homework and taking care of their grandchildren when they were not feeling well.

    About three grandparents in four (76%) said that their motivation for helping out was to give their grandchildren’s parents some time out from childcare responsibilities. A similar percentage – 70% – said they wanted to provide some economic support, either by offering financial assistance or by allowing parents to go to work.

    Just over half of grandparents (52%) said that being able to provide emotional support was what drove their motivation to provide grandchild care: they wanted to feel engaged with young people and help their grandchildren develop. But 17% say that they felt obliged to help out, and found it difficult to refuse.

    The grandmother’s role

    But while we tend to talk about “grandparents” as a group, grandmothers and grandfathers often experience and approach caregiving in distinctly different ways.

    In particular, when examining the specific activities undertaken with their grandchildren, there are clear gender distinctions. I found that grandmothers were more likely than grandfathers to engage in hands-on tasks: preparing meals, helping with homework, caring for grandchildren when they are sick, and doing school pick-ups.

    Grandfathers were less likely to do hands-on caring activities, such as school pickups.
    Rawpixel.com/Shutterstock

    Grandfathers, while also involved, tended to participate less in these activities. This is the case even among grandparent couples who lived together and jointly cared for their grandchildren.

    The role of wealth

    The extent and nature of grandparental care is also closely linked to grandparents’ socioeconomic status. For example, grandparents with fewer financial resources tended to offer childcare more regularly than their wealthier counterparts.

    Socioeconomic disparities also shape the nature of caregiving tasks. Less affluent grandparents were more likely to engage in hands-on activities, such as cooking meals and taking their grandchildren to and from school. In contrast, grandparents with more education were more likely than those with less education to help with homework frequently.

    The reasons for providing care also varied according to grandparents’ socioeconomic status. Grandparents with greater financial resources and higher levels of education were more likely to report providing childcare to help parents manage work and other responsibilities, as well as to offer emotional support to their grandchildren. Conversely, those with fewer financial resources were more likely to feel obliged to help or to struggle to refuse caregiving duties.

    Grandparent wellbeing

    What grandparents do with their grandchildren and why they have an active role in caring for them can also affect their wellbeing in complex ways. Grandparents who often took part in fun or enriching activities with their grandchildren, such as leisure activities or helping with homework, tended to report higher wellbeing compared to their peers who did not look after grandchildren.

    However, grandparents who cared for their grandchildren when they were sick or who had them stay overnight without parents tended to report, over time, lower wellbeing.

    Motivations also matter for grandparents’ wellbeing. Grandparents had a higher quality of life if they cared for their grandchildren because they wanted to help them develop as people, or to feel engaged with young people. However, grandparents who felt obliged to help, perhaps due to family pressure or lack of alternatives, experienced lower wellbeing.

    In short, these findings remind us that behind the broad label of “grandparenting” lies a diverse world of individuals whose involvement in caring for grandchildren – how often they care, what they do, and why – is closely linked to and varies with gender norms and socioeconomic status.

    Also, the meaning behind grandparenting and the type of interactions shared with grandchildren seems to matter for grandparents’ wellbeing. Overall, these insights suggest that these caring responsibilities may contribute to the reinforcement or even deepening of existing gender, socioeconomic and health inequalities among older adults.

    MIL OSI Analysis

  • MIL-OSI Analysis: Congress has a chequered history of overseeing US intelligence and national security

    Source: The Conversation – UK – By Luca Trenta, Associate Professor in International Relations, Swansea University

    Tonya Ugoretz, a top FBI intelligence analyst, was placed on administrative leave in June. The FBI has not said why. But the decision came around the time she refused to endorse what was reportedly a thinly sourced report accusing China of interfering in the 2020 US presidential election in favour of Joe Biden.

    At the Bureau, loyalty tests and polygraph checks have also allegedly become routine as part of a crackdown on news leaks. When approached by the New York Times about the matter, the FBI declined to comment and cited “personnel matters and internal deliberations”.

    The situation does not seem to be much different at the CIA. In May, agency director John Ratcliffe ordered a review of the intelligence community’s earlier conclusion that Russia had interfered in the 2016 presidential campaign on behalf of Donald Trump. The conclusion, Ratcliffe contends, was unwarranted and imposed by political pressure – a claim that has been rejected by one of the report’s leading authors.

    The intelligence community has reportedly also been under pressure to substantiate Trump’s claims that the recent military strikes on Iran had obliterated its nuclear sites. This is despite mixed evidence regarding the extent of their success. These examples suggest a growing politicisation of intelligence and national security in the US.

    Researchers and observers have highlighted the detrimental effect of this process. When intelligence is conducted by ideologues that are screened for loyalty, it often becomes more about pleasing the leader than collecting accurate information and preventing failure.

    Less attention has been paid to the permissive attitude of Congress. Many Republicans in Congress have taken an unquestioning attitude toward the claims made by the president and other officials, allowing intelligence agencies to pursue Trump’s agenda unimpeded.

    While Trump and Patel’s focus on personal loyalty when it comes to intelligence is new, partisan influence in congressional oversight is not. In fact, Congress has a long history of supporting the intelligence priorities of the governing administration.

    For much of the cold war, Congress was not involved – and did not want to be involved – in matters of intelligence. This view was expressed by former CIA legal counsel, Walter Pforzheimer, during an interview in 1988. Reflecting on the early days of oversight, he stated: “It wasn’t that we were attempting to hide anything. Our main problem was we couldn’t get them [Congress] to sit still and listen.”

    This quote isn’t entirely true. In research from 2023, I showed that Congress was more involved than was generally believed. The US-backed 1954 coup in Guatemala, which deposed the democratically elected president, Jacobo Árbenz, is a case in point. Leading members of Congress were “in the know” and others pushed Dwight Eisenhower’s administration to be even more aggressive.

    But Congress took on a more active role in intelligence matters in the 1970s. Following a series of public revelations about the CIA’s behaviour, a select committee was established in 1975 and exposed abuses by intelligence agencies including the surveillance of US citizens, experiments with drugs and involvement in assassinations.

    In the wake of this, Congress established intelligence committees with oversight duties. The idea was that the CIA would present a document signed by the president to notify congressional committees of its intentions.

    However, the system ran into trouble in the 1980s, and partisanship and politicisation were part of the story. The Ronald Reagan administration’s support for the “contra” rebels in Nicaragua made intelligence a matter of severe partisan conflict.

    Removing Nicaragua’s government

    When Reagan took office in 1981, one of the primary foreign policy priorities for his administration was removing the Sandinista National Liberation Front from power in Nicaragua. The administration saw the Sandinistas as a threat to the region and – in Reagan’s black-and-white thinking – as puppets of Communist Moscow and Havana.

    The administration sought to convince Congress that its aims were limited. The aim, or so CIA director William Casey told the intelligence committees, was to obstruct the transfer of weapons from Nicaragua to neighbouring El Salvador. Another left-wing guerrilla movement, the Farabundo Martí National Liberation Front, was threatening the US-supported government there.

    Initially, the policy received bipartisan support in Congress. The linchpin of this policy was the creation of an insurgent group in Nicaragua called the contras (contrarevolucionarios). It was made up of members of the previous regime’s brutal national guard, as well as other groups that had become disgruntled with the Sandinistas.

    News stories soon made clear that the size of the contra army had radically expanded, from the 500 members discussed by Casey in his initial briefing to thousands. The contras’ stated goal of overthrowing the Sandinistas, which they ultimately failed to do, also contradicted the earlier Reagan administration’s statements to Congress.

    Democrats in Congress pushed the leadership of intelligence committees to curtail the administration’s activities. Edward Boland, chairman of the House Intelligence Committee, penned and helped to pass two amendments. The first prohibited any US government support for the purpose of overthrowing the Nicaraguan government.

    When the administration found loopholes to circumvent this, Boland’s second amendment prohibited any US funds from being spent in support of the contras. This amendment is generally understood as a first step towards the so-called Iran-Contra scandal.

    The Reagan administration illegally funded the contras behind Congress’s back by using the proceeds from secret arms sales to Iran – a state the US had been at loggerheads with since the 1979 Islamic revolution.

    The Boland amendments also helped make an intelligence and covert operations issue a matter of public debate and – more importantly – congressional votes. Republicans in Congress abandoned their oversight duties and followed the administration’s guidelines.

    Votes on contra aid became an opportunity for partisan controversy, vitriolic attacks, accusations of betrayal and large-scale influence campaigns. Instead of oversight, a deep partisan divide materialised.

    Counting on Congress? Think again

    The role of Congress is to conduct oversight. It is the role of the governing administration to keep Congress informed of intelligence matters, particularly covert operations. History shows this has often been hard to achieve.

    Congress has been complacent, complicit and often too willing to follow the government’s lead. In some cases, Congress has acted but primarily in the aftermath of major scandals or media revelations. This is called “firefighting” behaviour.

    But “firefighters” seem to now be in short supply. As much as domestic constraints on Trump’s power are decreasing, the same is happening in the context of intelligence and foreign policy.

    MIL OSI Analysis

  • MIL-OSI Analysis: Five reasons why driverless cars probably won’t take over your street any time soon

    Source: The Conversation – UK – By Seyed Toliyat, Lecturer in Business Analytics and Technology, University of Stirling

    Karolis Kavolelis/Shutterstock

    The UK government has launched a consultation on driverless cars, ahead of on-the-road trials of the vehicles next year. It has now been more than a decade since the prospect of driverless cars on public roads emerged, and prototypes and robotaxi fleets such as Waymo and Cruise replaced human drivers with artificial intelligence (AI).

    But ten years on, and with self-driving cars increasingly common in the US and China, significant obstacles still stand in their way in the UK.

    Despite rapid advances in the tech, other aspects of the driverless journey are still to catch up. Here are five key reasons why autonomous cars are unlikely to take over your local roads any time soon.

    1. Uncertainties around safety

    One of the main benefits of rolling out driverless cars is to increase traffic safety by eliminating driver errors. In the US, the National Highway Traffic Safety Administration reported in 2018 that more than 90% of serious crashes were due to human error. But there is not yet converging evidence to support the idea that AI taking over from human drivers can make roads safer.

    On the other hand, there is evidence that adverse weather conditions, road design, traffic control systems and mixed traffic (that is, human-driven and driverless cars) can degrade the performance of those vehicles. Anomalies in driving patterns and frequent rear-end crashes involving self-driving technologies could indicate the AI algorithms are still far from perfect.

    2. Regulations and legislation falling behind

    Substantial investment in research and development of self-driving technologies has led to a fast-growing and innovative industry. On the other hand, legislation and regulation processes often tend to be slower. These involve multiple stages including drafting, consultation, debate, committee reviews, voting and sometimes judicial review.

    The UK’s Automated Vehicles Act provides a framework for the deployment of driverless vehicles. But the legal codes and mechanisms are still evolving. This is also true of data privacy and cybersecurity.

    For now, there is insufficient legislation governing who can own telematics and vehicle data or how they can be used. Such a widening lag has implications for the mass rollout of driverless cars, and has a direct impact on insuring them.

    3. The insurance industry isn’t ready

    Scarce data, combined with ambiguities in legislation and regulations, means insurance companies face a new set of challenges. These include making sense of where liability lies, developing new insurance models and adapting their premiums as the types of claim evolve.

    In some countries, including the UK, the liability for levels four and five of autonomous driving (very highly automated and fully automated) is shifting from human drivers in conventional vehicles to the manufacturer. Although the insurer pays first, they can recover costs from the tech provider later.

    New risk factors such as cybersecurity further complicate the insurance landscape. Driverless cars are designed to communicate with infrastructure and even other vehicles to decide their routes and avoid collisions. This can open the door to unlawful modifications, hacking or privacy breaches.

    4. Ethical dilemmas

    Heavy traffic and the presence of other road users could lead to scenarios where a crash is inevitable. This would require programmers to design crash severity algorithms that include moral decision-making into autonomous systems. In simple terms, programmers are effectively being asked to write codes that assign value to human lives – an ethical minefield that has yet to be resolved in either academia or industry.

    This echoes the “trolley problem” (a thought experiment about killing one person to save others) but with real-world legal and moral significance. It poses further legal and regulatory questions that could further slow the progress of legislation. Complicating things further is the opaque, black-box nature of AI algorithms.

    5. Changing business models

    Technology developers such as Waymo and Zoox offer only driverless rides and don’t sell vehicles. The recent move by Tesla to launch a robotaxi service in Austin, Texas, also indicates a shift from selling cars to “mobility as a service”, even by car manufacturers.

    In some societies like the US, there is resistance among consumers to relinquishing car ownership due to higher car dependency. This mismatch between the business models of the makers of driverless cars and consumer preferences presents another significant barrier to widespread adoption.

    Even if the technical obstacles are removed, these deeply held sentiments about the nature of mobility may prevent consumers abandoning private vehicles.

    Until the technical, legal, ethical and commercial challenges are addressed, the widespread rollout of driverless vehicles will remain more of a long-term vision than an immediate reality.

    Under bright lights, the audience looks at a bare stage on two planes. Below, a small stage is white and empty, occupied only by a table and two chairs. Above, a huge, slanted mirror reflects a bird’s-eye view of the stage to the audience. Three middle-aged figures enter the stage without looking at each other. One lies down, staring into the mirror. One stands and one sits. For the next 70 minutes, they will never hold one another’s gaze.

    This is the revival of Sarah Kane’s play 4.48 Psychosis. The production takes place 25 years after the original work, bringing the original cast and creative team back to the Royal Court where the play was first staged – now transferred to The Other Place, a small theatre run by the Royal Shakespeare Company.

    It replicates the staging of the original with precision. The same faces are on the same set, making the same gestures. Even the projections of the street outside show cars from the 1990s. And yet, because this is theatre, there are inevitable differences.

    The play is a revival and a commemoration. Kane wrote 4.48 Psychosis in the year leading up to her death by suicide in 1999 and completed it during her final stay in a psychiatric hospital. It stages the experience of a suicidal and psychotic mind breaking down.

    About a week after sending the play to her agent, Kane ended her own life. A year later, the original production was staged at the Royal Court, directed by her long-term collaborator James Macdonald and starring three young actors: Daniel Evans, Madeleine Potter and Jo McInnes. All three have returned for this revival.

    4.48 Psychosis is a highly experimental play. It contains dialogue between doctor and patient, poetry, seemingly psychotic speech, lists and quotations from literature and medical documents. In her aims for the play, Kane was both very open and very specific. She described the play in an interview at Royal Holloway University as an attempt to stage the experience of a mind breaking down:

    I’m writing a play called 4:48 Psychosis … It’s about a psychotic breakdown and what happens in a person’s mind when the barriers which distinguish between reality and different forms of imagination completely disappear … you no longer know where you stop and the world starts.

    What’s more, through an experimental style, Kane hoped to make her audience experience some of the distress experienced by the mental collapse being staged. She described this as “making form and content one”.

    How this strange work was to be staged was to be left up to future creatives. She didn’t specify how many actors should perform the work, or provide references to their age or gender. Kane believed that as a playwright, her job was to write the work, and then let directors figure it out.

    The result was that the first performance split the experience of breakdown across three actors. At times, they take on more specific roles such as a patient, a doctor, and a lover or bystander. At others, they all seem to occupy a shared mental reverie.

    Since the original production, 4.48 Psychosis has been staged in multiple ways around the world. French actor Isabelle Huppert performed the first French production largely as a monologue in 2005, with occasional lines delivered by Gérard Watkins as a psychiatrist. Recently in the UK it has been transformed into a successful opera in which a six-person ensemble and full orchestra performed the play’s “hive mind”, and has been performed in a plastic box in British Sign Language.

    When it was first performed in 2000, a year after Kane’s death, the play left a profound impression on its audiences. It was arguably one of the most brutal, head-on representations of mental illness that had ever been seen in British theatre. Reviews from that first production discuss anxieties about whether the play should be viewed as a “suicide note” – a disturbingly “real” reference to Kane’s death.

    Today, such anxieties may seem less relevant. After all, over two decades have passed since Kane’s death, and we are in a very different world when it comes to how we view disclosure of personal struggle. In a culture of mental health awareness campaigns and social media oversharing, the closeness of Kane’s suffering to her work seems less scandalous, and perhaps less unsettling.

    At times, this revival feels a bit more like a repetition, or archival reconstruction than a fresh performance. There are moments that feel dated – for example, the use of pixelated projections.

    The most compelling moments were where something original was introduced due to the more advanced ages of the actors. In my experience, the play is typically performed by a younger cast, as a rageful, energetic cry of despair. It hits differently with a cast in their fifties.

    Madeleine Potter’s resigned, ironic complaints about being mistreated by “Dr This and Dr That” gave the impression of a woman with a lifetime’s experience of inadequate mental health services. And Jo McInnes’s desperate monologue about lost love could be referencing an estranged or dead child, as much as a lover.

    These moments inserted something new into Kane’s iconic last work and underlined that mental suffering is far from being the privilege of the young. More of a slow burn than an explosive cry of anger, this return to 4.48 Psychosis explores mental torment that can persist over a lifetime, revealing it to be as relevant as ever.

    4.48 Psychosis is at The Other Place until July 27.

  • MIL-OSI Submissions: Understanding the violence against Alawites and Druze in Syria after Assad

    In July 2025, clashes between the Druze religious minority and Sunni Arabs backed by government-affiliated forces led to hundreds of deaths in Sweida province in southern Syria. Israel later launched dozens of airstrikes in support of the Druze.

    This eruption of violence was an eerie reminder of what had unfolded in March 2025 when supporters of the fallen regime led by Bashar Assad, an Alawite, targeted security units. In retaliation, militias affiliated with the newly formed government in Damascus carried out indiscriminate killings of Alawites.

    While exact figures remain difficult to verify, more than 1,300 individuals, most of them Alawites, lost their lives. In some cases, entire families were summarily executed.

    Although the Syrian government promised an investigation into the atrocities, home invasions, kidnappings of Alawite women and extrajudicial executions of Alawite men continue.

    The violence in Sweida also bore a sectarian dimension, pitting members of a religious minority against armed groups aligned with the country’s Sunni majority.

    A key difference, however, involved the active Israeli support for the Druze and the U.S. efforts to broker a ceasefire.

    Post-Assad Syria has seen promising developments, including the lifting of international sanctions, a resurgence of civil society and the end of diplomatic isolation. There was even a limited rapprochement with the main Kurdish political party controlling northeastern Syria.

    The persistent violence targeting the Alawites and, to a more limited extent, the Druze, starkly contrasts with these trends. As a scholar of religious minorities and the Middle East, I argue that the current political situation reflects their historical persecution and marginalization.

    History of the Alawites

    The Alawites emerged as a distinct religious community in the 10th century in the region of the Latakia coastal mountains, which today make up northwestern Syria.

    Although their beliefs have some commonalities with Shiite Islam, the Alawites maintain their own unique religious leadership and rituals. Under the Ottoman regime in the late 19th century, they benefited from reforms such as the expansion of educational opportunities and economic modernization, while gaining geographical and social mobility.

    After Hafez Assad, the father of Bashar, came to power in a coup in 1970, he drew upon his Alawite base to reinforce his regime. Consequently, Alawites became disproportionately represented in the officer corps and intelligence services.

    Prior to the civil war, which began in 2011, their population was estimated at around 2 million, constituting roughly 10% of Syria’s population. During the civil war, Alawite young men fighting for the regime suffered heavy casualties. However, most Alawites remained in Syria, while Sunni Arabs and Kurds were disproportionately displaced or became refugees.

    Among Syria’s minorities, two key factors make the Alawites most vulnerable to mass violence in post-Assad Syria. The first factor is that, like the Druze, Alawites have their own distinct beliefs that deviate from Sunni Islam. Their religious practices and teachings are often described as “esoteric” and remain mostly inaccessible to outsiders.

    In my 2024 book “Liminal Minorities: Religious Difference and Mass Violence in Muslim Societies,” I categorize the Alawites and Druze in Syria alongside Yezidis in Iraq, Alevis in Turkey and Baha’is in Iran as “liminal minorities” – religious groups subject to deep-seated stigmas transmitted across generations.

    These groups are often treated as heretics who split from Islam and whose beliefs and rituals are deemed beyond the pale of acceptance. For instance, according to Alawite beliefs, Ali, the son-in-law of Prophet Muhammad, is a divine manifestation of God, which challenges the idea of strict monotheism central to Sunni Islam.

    From the perspective of Sunni orthodoxy, these groups’ beliefs have been a source of suspicion and disdain. A series of fatwas by prominent Sunni clerics from the 14th to the 19th century declared Alawites heretics.

    Resentment against the Alawites

    The second factor contributing to the Alawites’ vulnerability is the widespread perception that they were the main beneficiaries of the Assad regime, which engaged in mass murder against its own citizens. Although power remained narrowly concentrated under Assad, many Alawites occupied key positions in the security apparatus as well as the government.

    In today’s political landscape where the central government remains weak and its control over various armed groups is limited, religious stigmatization and political resentment create fertile ground for mass violence targeting the Alawites.

    The massacres of March 2025 were accompanied by sectarian hate speech, including open calls for the extermination of the Alawites, both in the streets and on social media.

    While many Sunni Muslims in Syria also perceive the Druze as heretics, they maintained a greater degree of distance from the Assad regime and were less integrated into its security apparatus.

    Nonetheless, in recent months the situation deteriorated rapidly in the Druze heartland. The Druze militias and local Bedouin tribes engaged in heavy fighting in July 2025. Unlike the Alawites, the Druze received direct military assistance from Israel, which has its small but influential Druze population. This further complicates peaceful coexistence among religious groups in post-Assad Syria.

    A sober future

    Sunni Arab identity is central to the newly formed government in Damascus, which can come at the expense of religious and ethnic pluralism. However, it has incentives to rein in arbitrary violence against the Alawites and Druze. Projecting itself as a source of order and national unity helps the government internationally, both diplomatically and economically.

    Internally, however, the new government remains fractured and lacks effective control over vast swaths of territory. While it pays lip service to transitional justice, it is also cautious about being perceived as overly lenient toward individuals associated with the Assad regime and its crimes. Meanwhile, Alawite and Druze demands for regional autonomy continue to stoke popular Sunni resentments and risk triggering further cycles of instability and violence.

    I believe that in a post-Assad Syria defined by fractured governance and episodic retribution, the Alawites as well as Druze are likely to face deepening marginalization.

  • MIL-OSI Submissions: Binary star systems are complex astronomical objects − a new AI approach could pin down their properties quickly

    Source: The Conversation – USA – By Andrej Prša, Professor of Astrophysics and Planetary Science, Villanova University

    In a binary star system, two stars orbit around each other. ESO/L. Calçada, CC BY

    Stars are the fundamental building blocks of our universe. Most stars host planets, like our Sun hosts our solar system, and if you look more broadly, groups of stars make up huge structures such as clusters and galaxies. So before astrophysicists can attempt to understand these large-scale structures, we first need to understand basic properties of stars, such as their mass, radius and temperature.

    But measuring these basic properties has proved exceedingly difficult. This is because stars are quite literally at astronomical distances. If our Sun were a basketball on the East Coast of the U.S., then the closest star, Proxima, would be an orange in Hawaii. Even the world’s largest telescopes cannot resolve an orange in Hawaii. Measuring radii and masses of stars appears to be out of scientists’ reach.

    Enter binary stars. Binaries are systems of two stars revolving around a mutual center of mass. Their motion is governed by Kepler’s harmonic law, which connects three important quantities: the sizes of each orbit, the time it takes for them to orbit, called the orbital period, and the total mass of the system.

    I’m an astronomer, and my research team has been working on advancing our theoretical understanding and modeling approaches to binary stars and multiple stellar systems. For the past two decades we’ve also been pioneering the use of artificial intelligence in interpreting observations of these cornerstone celestial objects.

    Measuring stellar masses

    Astronomers can measure orbital size and period of a binary system easily enough from observations, so with those two pieces they can calculate the total mass of the system. Kepler’s harmonic law acts as a scale to weigh celestial bodies.

    Binary stars orbit around each other, and in eclipsing binary stars, one passes in front of the other, relative to the telescope lens.

    Think of a playground seesaw. If the two kids weigh about the same, they’ll have to sit at about the same distance from the midpoint. If, however, one child is bigger, he or she will have to sit closer, and the smaller kid farther from the midpoint.

    It’s the same with stars: The more massive the star in a binary pair, the closer to the center it is and the slower it revolves about the center. When astronomers measure the speeds at which the stars move, they can also tell how large the stars’ orbits are, and as a result, what they must weigh.

    Measuring stellar radii

    Kepler’s harmonic law, unfortunately, tells astronomers nothing about the radii of stars. For those, astronomers rely on another serendipitous feature of Mother Nature.

    Binary star orbits are oriented randomly. Sometimes, it happens that a telescope’s line of sight aligns with the plane a binary star system orbits on. This fortuitous alignment means the stars eclipse one another as they revolve about the center. The shapes of these eclipses allow astronomers to find out the stars’ radii using straightforward geometry. These systems are called eclipsing binary stars.

    By taking measurements from an eclipsing binary star system, astronomers can measure the radii of the stars.

    More than half of all Sun-like stars are found in binaries, and eclipsing binaries account for about 1% to 2% of all stars. That may sound low, but the universe is vast, so there are lots and lots of eclipsing systems out there – hundreds of millions in our galaxy alone.

    By observing eclipsing binaries, astronomers can measure not only the masses and radii of stars but also how hot and how bright they are.

    Complex problems require complex computing

    Even with eclipsing binaries, measuring the properties of stars is no easy task. Stars are deformed as they rotate and pull on each other in a binary system. They interact, they irradiate one another, they can have spots and magnetic fields, and they can be tilted this way or that.

    To study them, astronomers use complex models that have many knobs and switches. As an input, the models take parameters – for example, a star’s shape and size, its orbital properties, or how much light it emits – to predict how an observer would see such an eclipsing binary system.

    Computer models take time. Computing model predictions typically takes a few minutes. To be sure that we can trust them, we need to try lots of parameter combinations – typically tens of millions.

    This many combinations requires hundreds of millions of minutes of compute time, just to determine basic properties of stars. That amounts to over 200 years of computer time.

    Computers linked in a cluster can compute faster, but even using a computer cluster, it takes three or more weeks to “solve,” or determine all the parameters for, a single binary. This challenge explains why there are only about 300 stars for which astronomers have accurate measurements of their fundamental parameters.

    The models used to solve these systems have already been heavily optimized and can’t go much faster than they already do. So, researchers need an entirely new approach to reducing computing time.

    Using deep learning

    One solution my research team has explored involves deep-learning neural networks. The basic idea is simple: We wanted to replace a computationally expensive physical model with a much faster AI-based model.

    First, we computed a huge database of predictions about a hypothetical binary star – using the features that astronomers can readily observe – where we varied the hypothetical binary star’s properties. We are talking hundreds of millions of parameter combinations. Then, we compared these results to the actual observations to see which ones best match up. AI and neural networks are ideally suited for this task.

    In a nutshell, neural networks are mappings. They map a certain known input to a given output. In our case, they map the properties of eclipsing binaries to the expected predictions. Neural networks emulate the model of a binary but without having to account for all the complexity of the physical model.

    Neural networks detect patterns and use their training to predict an output, based on an input.

    We train the neural network by showing it each prediction from our database, along with the set of properties used to generate it. Once fully trained, the neural network will be able to accurately predict what astronomers should observe from the given properties of a binary system.

    Compared to a few minutes of runtime for the physical model, a neural network uses artificial intelligence to get the same result within a tiny fraction of a second.

    Reaping the benefits

    A tiny fraction of a second works out to about a millionfold runtime reduction. This brings the time down from weeks on a supercomputer to mere minutes on a single laptop. It also means that we can analyze hundreds of thousands of binary systems in a couple of weeks on a computer cluster.

    This reduction means we can obtain fundamental properties – stellar masses, radii, temperatures and luminosities – for every eclipsing binary star ever observed within a month or two. The big challenge remaining is to show that AI results really give the same results as the physical model.

    This task is the crux of my team’s new paper. In it we’ve shown that, indeed, the AI-driven model yields the same results as the physical model across over 99% of parameter combinations. This result means the AI’s performance is robust. Our next step? Deploy the AI on all observed eclipsing binaries.

    Best of all? While we applied this methodology to binaries, the basic principle applies to any complex physical model out there. Similar AI models are already speeding up many real-world applications, from weather forecasting to stock market analysis.

  • MIL-OSI Analysis: Understanding how Taylor Swift constructs her songs helps explain her phenomenal popularity

    Source: The Conversation – Canada – By Alexander Carpenter, Professor, Musicology, University of Alberta

    In 2023, Forbes published an article about Taylor Swift that included the following mind-boggling statistic: 55 per cent of adults in the United States identify themselves as Swift fans.

    In the wake of her recent epic world tour — which drew 10 million attendees and earned billions of dollars — Swift has clearly emerged as a modern singer-songwriter whose success and renown has no equal.

    The same article reports that 73 per cent of those surveyed insisted that “Swift’s music is a driving force of their support of her.” But the abundant discourse surrounding Taylor Swift in the popular press, academia and online seems to be about everything but her songs.

    In place of critical engagement with her musical work, Swift is credited for creating her own economic ecosystem wherever she goes, lauded for being a shrewd and powerful businessperson, described as an empowered and empowering feminist icon or branded a quintessential entertainer.

    At this moment, Swift resides at the very apex of modern celebrity culture. Ironically, this makes it especially tricky to engage with Swift as a musician, which is the very basis of her fame.

    As a musicologist, music critic and musician who studies and teaches popular music, there are ways to examine the musical meaning of pop songs. These approaches provide useful insights; after all, wasn’t it the music that drew audiences to Swift in the first place?

    Studying Swift

    Swift is increasingly taken seriously in the halls of academia. A number of universities offer courses dedicated to Swift, but typically not to her music as such: rather, many of these courses take a literary approach to her songs or a broadly sociological approach to her as a pop culture phenomenon, or they foreground her business model.

    In his book There’s Nothing Like This, Kevin Evers, senior editor of the Harvard Business Review, regards Swift as a “strategic genius.” He examines how she identifies and exploits untapped markets, making creative and marketing pivots at key moments while protecting her image as a self-made, authentic singer-songwriter.

    Evers focuses on non-musical elements when discussing Swift’s songs. He claims that Swift’s fans interpret her lyrics in a manner akin to the literary analysis of complex poems. Swift’s songs intrigue fans, Evers insists, primarily because they offer insight into her personal life, romantic travails and struggles with fame.

    Of course, words are an important element of pop songs, and for many fans, the words of a song constitute its “about-ness.” But a pop song is a sonic object, not simply a delivery system for words.

    Lyrical discourse analysis

    Song lyrics are not poems, although they may be “like poetry,” as musicologist Dai Griffiths has argued. He points out that when we insist on thinking of lyrics as poetry, we lose a systematic understanding of how words function in songs. The placement and sound of words, and how they relate to the music, are key elements of a song’s musical structure and sense.

    It is this discussion of the musical sense and meaning of Swift’s songs that is largely neglected.

    The academic study of classical music offers a wealth of analytic methodologies; there are ways to examine the musical meaning of pop songs that do not over-analyze the song. These include looking at elements like form, orchestration, melody, harmony and rhythm.

    A song creates space: its formal layout and the rhythm of musical phrases provide the space for words — what Griffiths calls the “verbal space” — which have their own rhythms and structures and work within but also push against the boundaries of this space.

    Form and space

    Consider Swift’s chart-topping 2014 single, “Shake it Off,” re-released as “Shake it Off (Taylor’s Version)” in 2023. This song, while popular, was criticized for its repetitiveness and lack of emotional depth.

    “Shake it Off” doesn’t seem to have much lyrical content: the verses are short, rounded off with simple slant rhymes, and much of the created space seems to be filled with repetition: “I’m just gonna shake, shake, shake, shake, shake/Shake it off, shake it off.”

    Likewise, the song is built musically on some very basic and limited material, namely three chords, a short, unvaried drum loop and a spare bass line provided by a baritone saxophone.

    The lyric video to “Shake it Off (Taylor’s version).”

    The lyrics touch lightly on Swift’s response to fame and her critics, but it is their syllabic density that contributes to the song’s development and momentum. This gradually and sytematically increases over the first two verses and pre-chorus, until arriving at the chorus, where the space is filled almost completely.

    The density of the music also increases in the choruses, with a thicker bass part, added vocals and a brass fanfare.

    While “Shake it Off” is repetitive with little harmonic and melodic variety, it is also quite subtly counterbalanced with a variety of sounds, textures and densities. These move the song forward and importantly, help mark off the song’s formal sections.

    These compositional and production details contribute to the song’s overall meaning. But how the words participate in the unfolding of the song-as-music, or the creation and shaping of the musical space, is also meaningful. The thrust of the lyrics emphasize Swift’s detachment from gossip and criticism: “I never miss a beat/I’m lightnin’ on my feet” and “But I keep cruisin’/Can’t stop, won’t stop groovin’”.

    These lyrics are reinforced by the propulsive musical momentum of the song created by the gradual thickening of the text and music. Even with this thickening, the song still remains quite light, emphasizing the lyrical claims of detachment and distance from negativity.

    The chorus, by contrast, with its deeply resonant bass, layers of background vocals and added brass, is musically the heaviest part of the song, underwriting Swift’s assertive claim that she will “shake off” the lies and gossip that plague her as a celebrity pop star.

    Understanding Swift’s success

    Collecting some musical information about Swift’s songs is not an abstract or intellectual activity; rather, it is essential information if we want to better understand Swift and her success in terms of her song writing.

    I’m not making an argument here for or against Swift’s music; I’m neither a “Swiftie” nor a detractor. Nor have I offered anything like a comprehensive or definitive analysis of a song in this short article.

    But I do think we should be curious and better understand Swift’s success, especially the popularity of her music across generations and demographics. How her songs are actually put together — how they work as music, in tandem with words, to tell stories — is an essential part of that understanding.

  • MIL-OSI Analysis: What Canada can learn from Australia on adequately protecting citizens at live events

    Source: The Conversation – Canada – By Sean Spence, Security Risk Management Pracitioner & Researcher, Royal Military College of Canada

    In April 2025, a man drove an SUV through a crowd of people attending a Filipino cultural festival in Vancouver, killing 11 people and injuring dozens more. In response, the British Columbia government immediately commissioned an inquiry to examine the systemic causes of the incident and whether any lessons could be learned from the tragedy.

    Vancouver SUV attack exposes crowd management falldowns and casts a pall on Canada’s election


    The commission came up with six recommendations based on gaps in the current municipal application and approval system for public events across the province.

    One key recommendation was that all public events should be required to complete a risk assessment. This isn’t currently happening across the province. The absence of such analysis poses a risk for public safety.

    Another recommendation was the creation of local knowledge capacity to support event organizers, particularly for small and rural events, where the expertise to conduct a basic security risk assessment is lacking.

    Forseeable tragedy?

    As I argued in August 2022, the live events industry lacks the same level of professionalism as other occupations. Many of these small event organizers are amateurs who lack the resources to properly deal with the security risks involved in holding their events.




    Read more:
    Canada could have its own Fyre Festival fiasco if it doesn’t amp up event regulations


    These factors, combined with emerging security risks, meant that the tragedy at the Lapu Lapu festival could be considered a foreseeable event given the risk realities associated with modern mass gatherings.

    The inquiry report highlighted how B.C. is lagging behind other international jurisdictions in terms of legislative pro-activeness in securing public events. This policy deficiency is actually a Canada-wide problem; the country is woefully behind other western nations when it comes to securing public events.

    My doctoral thesis examined this very issue when I compared the regulation and application process to host public events in Canada and Australia’s largest cities.

    Australia vs. Canada

    Firstly, it’s important to note that Canada is a less safe country in terms of security than Australia, all things considered equal. Canada’s porous border with the United States means more illegal firearms are entering the country, resulting in more gun violence than in Australia, where there are more restrictive gun ownership laws.

    The Lapu Lapu attack was not investigated as an act of terrorism, but in a related concern, Canada’s intelligence-gathering and national security laws place it at a counter-terrorism disadvantage compared to Australia.

    Relatively speaking, research suggests Canada’s Charter of Rights and Freedoms hinders its security services from being able to detect and investigate terrorism-related offences given the greater importance placed on individual rights compared to Australia, where there is no such Charter equivalent.

    Australia also has pro-active foreign intelligence collection capabilities to aid in its counter-terrorism efforts, while Canada’s CSIS agency only has domestic capabilities. That essentially requires it to import intelligence from its allies.

    Given these facts, it would seem plausible that Canada would be at greater risk for security threats at public events — including terrorist attacks, active shooters, etc. — than Australia.

    When I compared the data between both countries in my research, it suggested Australia has more public event regulation than Canada.

    It was quantitatively shown that Australian officials require risk assessments and other proactive measures from event organizers, including for risk mitigation, while Canadian officials are mostly concerned with reactive security response plans — in other words, determining how organizers would respond to attacks after they occurred.

    An analysis of event application documents in both countries reveal that Australian municipalities disproportionately emphasize “risk management” in approving events compared to Canadian municipalities.

    Three ways the B.C. report falls short

    The B.C. report missed out on examining several important elements.

    Firstly, it did not take a holistic, deep dive into just how vulnerable public events are to myriad security threats — like active shooters, crowd crushing and terrorist attacks — but instead focused solely on the hostile vehicle threat.

    It also failed to consider the urgency of governments to adopt policy changes in the face of emerging threats on public spaces, like drone attacks.

    Secondly, the report made no mention of the need for law enforcement to develop stronger ties to share intelligence with event organizers as a proactive measure to protect mass gathering events from violence. The Hamas attacks at a music festival in Israel in October 2023 highlight the worst outcome of such failures.

    How Israel underestimated Hamas’s intelligence capabilities – an expert reviews the evidence


    Lastly, there was no call for action or recommendation for the federal government to play a greater role in providing guidance to the industry and lower levels of government.

    National security is a federal issue as well as the regulation of airspace for drones. In countries such as the United Kingdom, Australia and the United States, the national government provides guidance on protecting public spaces. There is no such policy leadership in Canada.

    The B.C. findings show Canadian authorities have a lot of work to do to make public events safer for Canadians. With the FIFA World Cup coming to Canada next year, Canadian governments still have time to implement corrective actions to ensure soccer fans stay safe.

    On hot summer days, few things are more refreshing than a dip in the pool. But have you ever wondered if the pool is as clean as that crystal blue water appears?

    As an immunologist and infectious disease specialist, I study how germs spread in public spaces and how to prevent the spread. I even teach a course called “The Infections of Leisure” where we explore the risks tied to recreational activities and discuss precautions, while also taking care not to turn students into germophobes.

    Swimming, especially in public pools and water parks, comes with its own unique set of risks — from minor skin irritations to gastrointestinal infections. But swimming also has a plethora of physical, social and mental health benefits. With some knowledge and a little vigilance, you can enjoy the water without worrying about what might be lurking beneath the surface.

    The reality of pool germs

    Summer news headlines and social media posts often spotlight the “ick-factor” of communal swimming spaces. These concerns do have some merit.

    The good news is that chlorine, which is widely used in pools, is effective at killing many pathogens. The not-so-good news is that chlorine does not work instantly – and it doesn’t kill everything.

    Every summer, the Centers for Disease Control and Prevention issues alerts about swimming-related outbreaks of illness caused by exposure to germs in public pools and water parks. A 2023 CDC report tracked over 200 pool-associated outbreaks from 2015 to 2019 across the U.S., affecting more than 3,600 people. These outbreaks included skin infections, respiratory issues, ear infections and gastrointestinal distress. Many of the outcomes from such infections are mild, but some can be serious.

    Germs and disinfectants

    Even in a pool that’s properly treated with chlorine, some pathogens can linger for minutes to days. One of the most common culprits is Cryptosporidium, a microscopic germ that causes watery diarrhea. This single-celled parasite has a tough outer shell that allows it to survive in chlorine-treated water for up to 10 days. It spreads when fecal matter — often from someone with diarrhea — enters the water and is swallowed by another swimmer. Even a tiny amount, invisible to the eye, can infect dozens of people.

    Showering before and after swimming in a public pool helps avoid both bringing in and taking out pathogens and body substances.

    Another common germ is Pseudomonas aeruginosa, a bacterium that causes hot tub rash and swimmer’s ear. Viruses like norovirus and adenovirus can also linger in pool water and cause illness.

    Swimmers introduce a range of bodily residues to the water, including sweat, urine, oils and skin cells. These substances, especially sweat and urine, interact with chlorine to form chemical byproducts called chloramines that may pose health risks.

    These byproducts are responsible for that strong chlorine smell. A clean pool should actually lack a strong chlorine odor, as well as any other smells, of course. It is a common myth that a strong chlorine smell is a good sign of a clean pool. In fact, it may actually be a red flag that means the opposite – that the water is contaminated and should perhaps be avoided.

    How to play it safe at a public pool

    Most pool-related risks can be reduced with simple precautions by both the pool staff and swimmers. And while most pool-related illnesses won’t kill you, no one wants to spend their vacation or a week of beautiful summer days in the bathroom.

    These 10 tips can help you avoid germs at the pool:

    • Shower before swimming. Rinsing off for at least one minute removes most dirt and oils on the body that reduce chlorine’s effectiveness.

    • Avoid the pool if you’re sick, especially if you have diarrhea or an open wound. Germs can spread quickly in water.

    • Try to keep water out of your mouth to minimize the risk of ingesting germs.

    • Don’t swim if you have diarrhea to help prevent the spread of germs.

    • If diagnosed with cryptosporidiosis, often called “crypto,” wait two weeks after diarrhea stops before returning to the pool.

    • Take frequent bathroom breaks. For children and adults alike, regular bathroom breaks help prevent accidents in the pool.

    • Check diapers hourly and change them away from the pool to prevent fecal contamination.

    • Dry your ears thoroughly after swimming to help prevent swimmer’s ear.

    • Don’t swim with an open wound – or at least make sure it’s completely covered with a waterproof bandage to protect both you and others.

    • Shower after swimming to remove germs from your skin.

  • MIL-OSI Submissions: I teach college and report on Colorado media — there should be more professors doing the same in other states

    Source: The Conversation – USA (2) – By Corey Hutchins, Manager, Colorado College Journalism Institute, Colorado College

    Newsletters that cover a state’s media landscape are few and far between, according to a new report. iStock / Getty Images Plus

    Over the years, the crisis facing local news has meant the disappearance of reporting on the arts, politics, sports and local government.

    Newspapers have disappeared from many local communities, and the ranks of individual local journalists have plummeted over the past two decades.

    The retrenchment has also led to a loss of something else: reporters and columnists at local news organizations who decades ago regularly focused on their local media as a beat.

    There are very few of them left.

    I’m an instructor at Colorado College, where I manage the Journalism Institute. I also compulsively keep track of our state’s shifting media landscape.

    Recently, I produced a nationwide study called “Local News as a Public Good: Increasing Visibility Through University-Led Statewide Newsletters.”

    The Center for Community News at the University of Vermont solicited and published the report. The goal was to find out who is doing similar work and where.

    The Center for Community News is interested in fostering partnerships between academic programs and local newsrooms. The center is also seeking to find other ways higher-ed institutions are supporting their state’s media ecosystem — so they were especially interested in media newsletters being produced at a college or university.

    Few state-based newsletters

    The problem is, there weren’t many to track. I found just six, including my own, while researching for the report.

    Very few states, it turns out, “have a dedicated publication, site, or newsletter that regularly and independently reports on and analyzes ongoing developments in the local media scene,” the report found.

    ‘Inside the News in Colorado’ is the author’s newsletter, in which he obsessively tracks the media landscape in Colorado.

    My own weekly Substack newsletter is called “Inside the News in Colorado.” Each week, I report on, comment on and analyze the goings on in Colorado’s media scene. I connect local developments to what’s happening nationally, and I explore what makes the state’s local news ecosystem unique.

    My newsletter also pokes and prods, critiques and uplifts, and seeks to spark debate and a better understanding about the practice of local journalism. And it maintains a weekly running tab on the health of the state’s media landscape.

    Other newsletters across the country include NC Local, authored by Catherine Komp. The Newsroom Digest, out of the Center for Cooperative Media at Montclair State University in New Jersey, is another. Gateway Journalism Review from Southern Illinois University Carbondale’s School of Journalism, in the College of Arts and Media made the list. And Media Nation by Northeastern University professor Dan Kennedy in Massachusetts is another.

    Kennedy has been producing Media Nation for more than 20 years and writes more about national media issues. But he mixes it with plenty of local and regional happenings.

    If someone were to, say, leak an internal email from The Boston Globe, it is likely they would do so with Media Nation.

    The NC Local newsletter’s format is a mix of digestible roundups and some original reporting.

    A recurring item titled “Well Done” offers “noteworthy work from the NC news & information ecosystem.” The most-clicked links each week tend to come from a bulletin board section where Komp rounds up job postings and opportunities.

    The chunky Newsroom Digest newsletter highlights notable local journalism in New Jersey. It comes with a “Media Moves” section that introduces its audience to new local journalists and tracks newsroom personnel changes.

    While they differ in style and delivery, each is filling a gap in coverage in their state or region by reporting on an important industry: their own.

    “When I was at the (Boston) Phoenix, I think all of us at the alternative press thought big local media were a powerful local institution that ought to be held to account just like big business and everything else,” Media Nation’s Kennedy said for the report.

    Where to house the news about the news?

    I believe colleges and universities make good places to produce these kinds of state-based media newsletters.

    Journalism departments in particular are likely equipped to run them, especially if they have practitioners on the faculty. They are outside of a state’s established media organizations but also adjacent to them.

    Richard Watts, the director of the Center for Community News, commissioned the “Local News as a Public Good” study. He says there are important reasons for more newsletters consistently reporting on local media in individual states.

    “They draw attention to the key role local news plays by writing about the stories and the impact of those stories,” he said. “They help amplify and they showcase the importance of the media ecosystem for a vibrant democracy.”

    Furthermore, such newsletters can serve as the “canary in the coal mine to draw attention to media platforms in trouble, or actions by unscrupulous owners,” Watts added. “And they can share ideas and best practices across the system to help strengthen individual media platforms. And, lastly, they help create a community of stakeholders committed to the importance of a free press.”

    To that end, the Center for Community News at the University of Vermont is looking to help anyone in a higher-ed program who might be interested in launching a state-based media newsletter.

    “I think a really good person to do something like this is, first, someone who is doing more than just reporting on the industry or ecosystem,” said Komp of NC Local in the Center for Community News study.

    “It does need to be somebody who is engaging with journalists, with publishers, with journalism educators, with students, with funders, in ways that are not just reporting on what’s happening but in ways that are looking to always find solutions and address challenges.”

  • MIL-OSI Submissions: Caution in the C-suite: How business leaders are navigating Trump 2.0

    Source: The Conversation – USA (2) – By Erran Carmel, Professor of Business, American University Kogod School of Business

    In the first months of Donald Trump’s second term as president, his policies – from sweeping tariffs and aggressive immigration enforcement to attacks on diversity, equity and inclusion – have thrown U.S. businesses into turmoil, leading to a 26-point decline in CEO confidence.

    Yet despite this volatility, many American corporations have remained notably restrained in their public responses.

    This might come as a surprise. After all, in recent decades, CEOs have become increasingly willing to speak out about social and political issues. But while some universities and law firms have publicly pushed back against the Trump administration, business leaders are seemingly opting for caution.

    What would it take for these titans of corporate America to speak out against Trump’s policies? We are a professor and a graduate student who study business, and back in 2018, one of us – Dr. Carmel – conducted an analysis asking this very question. More recently, we gathered new data looking at how business leaders are responding to Trump’s second term.

    The 2018 analysis, involving data from about 200 leading U.S. CEOs, found that most business leaders remained publicly neutral on Trump, and only a handful expressed strong opposition. Silence was often a strategic choice, with many leaders staying mum due to fear of retaliation. The evidence also suggested that Trump could one day cross a line that would prompt a broader CEO backlash.

    Seven years later, that line hasn’t yet appeared, even as Trump’s footprint on corporate America is now far more direct and substantial.

    Most notable are Trump’s tariffs, first announced in April 2025, which have roiled global markets and unnerved CEOs. And there are many other ripples: Some companies, such as CBS’ parent company, Paramount – which is seeking the Trump administration’s approval for a merger – have decided to self-censor. Others, including Disney and Meta, gave in to Trump’s lawsuits and paid multimillion-dollar settlements, against the counsel of many outside experts. CEOs also have to deal with the threat of backlash from both the right and left.

    Against this backdrop, we collected new public data to see how corporate leaders are responding to the second Trump administration. Just as in 2018, we examined the 232 companies that make up the Business Roundtable – a club of the most powerful American businesses.

    We assessed the actions that these companies took regarding DEI and whether they experienced any backlash. We focused on these criteria as a way to assess whether CEOs are seeking either to support or placate Trump, or to stand on other principles. We also collected other data, including public statements from CEOs and campaign donations.

    DEI as a bellwether

    Corporate DEI actions were an early, useful way to gauge a business’s stances, since, from the outset, the Trump administration identified DEI as a “scourge” to be eliminated. Although the White House’s anti-DEI directives have applied to the executive branch and federal contractors, some private businesses rushed to make changes as well.

    By May, just a bit over 100 days into Trump’s second term, a significant number of companies had decided to go along with Trump’s preferences. Sixty-nine of the 232 companies in the Business Roundtable rolled back their DEI initiatives in some way, while just 20 companies announced that they kept their DEI programs in place. There’s no information either way on the remaining 61% – likely because they decided it’s better to stay out of the news.

    DEI-related actions have tapered off since May, but there’s still an impact. For example, the Federal Communications Commission pressured T-Mobile to eliminate DEI. Only then was its merger approved.

    Companies that scaled back their DEI initiatives sometimes pointed to the political environment as a factor. Meta, for example, said in an internal memo that it was ending its DEI efforts due to a “shifting legal and policy landscape.” Other companies, including Verizon and Comcast, reportedly rolled back DEI programs because they feared legal action by the federal government.

    Some corporations announced changes through internal announcements, legal filings or quiet updates to their websites, suggesting they want to stay out of the media spotlight.

    A small number of Business Roundtable companies stood firm on their DEI policies – to mixed results. When Marriott’s CEO voiced support for DEI at a corporate leadership event, he reportedly received 40,000 appreciative emails from employees. On the other hand, after Coca-Cola reiterated its “commitment to sponsoring an inclusive workplace,” the right-wing activist Robby Starbuck — who The New York Times has described as “the anti-DEI agitator that companies fear most” – said Coca-Cola “should be very nervous about continuing with its woke policies.”

    Bracing for backlash

    Overall, 22% of Business Roundtable companies saw some sort of backlash to their actions. Most came from the political right: 36 companies were called out by conservatives, another eight by progressives, and eight more faced bipartisan backlash.

    With more than three years left in Trump’s second term, it’s worth asking what lies ahead. We think the most likely scenario is that companies will continue to try to stay off the president’s radar and placate him when they must. After all, following the split with Elon Musk, Trump quite explicitly threatened to use presidential powers to hurt Musk’s businesses. Any CEO gets the implications.

    While our analysis primarily focused on social issues, policies at the business core may push U.S. companies to confront Trump. Tariff policy is a prime example. Back in April, major retailers like Walmart quietly warned Trump that tariffs could lead to empty shelves and higher prices. More recently, the CEO of Goldman Sachs publicly warned that tariffs “have raised the level of uncertainty to a degree I do not think is healthy for investment and growth.”

    These are voices of criticism – but worded quite softly.

  • MIL-OSI Submissions: 2 ways cities can beat the heat: Which is best, urban trees or cool roofs?

    Source: The Conversation – USA (2) – By Ian Smith, Research Scientist in Earth & Environment, Boston University

    When summer turns up the heat, cities can start to feel like an oven, as buildings and pavement trap the sun’s warmth and vehicles and air conditioners release more heat into the air.

    The temperature in an urban neighborhood with few trees can be more than 10 degrees Fahrenheit (5.5 Celsius) higher than in nearby suburbs. That means air conditioning works harder, straining the electrical grid and leaving communities vulnerable to power outages.

    There are some proven steps that cities can take to help cool the air – planting trees that provide shade and moisture, for example, or creating cool roofs that reflect solar energy away from the neighborhood rather than absorbing it.

    But do these steps pay off everywhere?

    We study heat risk in cities as urban ecologists and have been exploring the impact of tree-planting and reflective roofs in different cities and different neighborhoods across cities. What we’re learning can help cities and homeowners be more targeted in their efforts to beat the heat.

    The wonder of trees

    Urban trees offer a natural defense against rising temperatures. They cast shade and release water vapor through their leaves, a process akin to human sweating. That cools the surrounding air and reduces afternoon heat.

    Adding trees to city streets, parks and residential yards can make a meaningful difference in how hot a neighborhood feels, with blocks that have tree canopies nearly 3 F (1.7 C) cooler than blocks without trees.

    Comparing maps of New York’s vegetation and temperature shows the cooling effect of parks and neighborhoods with more trees. In the map on the left, lighter colors are areas with fewer trees. Light areas in the map on the right are hotter.

    But planting trees isn’t always simple.

    In hot, dry cities, trees often require irrigation to survive, which can strain already limited water resources. Trees must survive for decades to grow large enough to provide shade and release enough water vapor to reduce air temperatures.

    Annual maintenance costs – about US$900 per tree per year in Boston – can surpass the initial planting investment.

    Most challenging of all, dense urban neighborhoods where heat is most intense are often too packed with buildings and roads to grow more trees.

    How cool roofs can help on hot days

    Another option is “cool roofs.” Coating rooftops with reflective paint or using light-colored materials allows buildings to reflect more sunlight back into the atmosphere rather than absorbing it as heat.

    These roofs can lower the temperature inside an apartment building without air conditioning by about 2 to 6 F (1 to 3.3 C), and can cut peak cooling demand by as much as 27% in air-conditioned buildings, one study found. They can also provide immediate relief by reducing outdoor temperatures in densely populated areas. The maintenance costs are also lower than expanding urban forests.

    However, like trees, cool roofs come with limits. Cool roofs work better on flat roofs than sloped roofs with shingles, as flat roofs are often covered by heat-trapping rubber and are exposed to more direct sunlight over the course of an afternoon.

    Cities also have a finite number of rooftops that can be retrofitted. And in cities that already have many light-colored roofs, a few more might help lower cooling costs in those buildings, but they won’t do much more for the neighborhood.

    By weighing the trade-offs of both strategies, cities can design location-specific plans to beat the heat.

    Choosing the right mix of cooling solutions

    Many cities around the world have taken steps to adapt to extreme heat, with tree planting and cool roof programs that implement reflectivity requirements or incentivize cool roof adoption.

    In Detroit, nonprofit organizations have planted more than 166,000 trees since 1989. In Los Angeles, building codes now require new residential roofs to meet specific reflectivity standards.

    In a recent study, we analyzed Boston’s potential to lower heat in vulnerable neighborhoods across the city. The results demonstrate how a balanced, budget-conscious strategy could deliver significant cooling benefits.

    For example, we found that planting trees can cool the air 35% more than installing cool roofs in places where trees can actually be planted.

    However, many of the best places for new trees in Boston aren’t in the neighborhoods that need help. In these neighborhoods, we found that reflective roofs were the better choice.

    By investing less than 1% of the city’s annual operating budget, about US$34 million, in 2,500 new trees and 3,000 cool roofs targeting the most at-risk areas, we found that Boston could reduce heat exposure for nearly 80,000 residents. The results would reduce summertime afternoon air temperatures by over 1 F (0.6 C) in those neighborhoods.

    While that reduction might seem modest, reductions of this magnitude have been found to dramatically reduce heat-related illness and death, increase labor productivity and reduce energy costs associated with building cooling.

    Not every city will benefit from the same mix. Boston’s urban landscape includes many flat, black rooftops that reflect only about 12% of sunlight, making cool roofs that reflect over 65% of sunlight an especially effective intervention. Boston also has a relatively moist growing season that supports a thriving urban tree canopy, making both solutions viable.

    In places with fewer flat, dark rooftops suitable for cool roof conversion, tree planting may offer more value. Conversely, in cities with little room left for new trees or where extreme heat and drought limit tree survival, cool roofs may be the better bet.

    Phoenix, for example, already has many light-colored roofs. Trees might be an option there, but they will require irrigation.

    Getting the solutions where people need them

    Adding shade along sidewalks can do double-duty by giving pedestrians a place to get out of the sun and cooling buildings. In New York City, for example, street trees account for an estimated 25% of the entire urban forest.

    Cool roofs can be more difficult for a government to implement because they require working with building owners. That often means cities need to provide incentives. Louisville, Kentucky, for example, offers rebates of up to $2,000 for homeowners who install reflective roofing materials, and up to $5,000 for commercial businesses with flat roofs that use reflective coatings.

    In Boston, planting trees, left, and increasing roof reflectivity, right, were both found to be effective ways to cool urban areas.
    Ian Smith et al. 2025

    Efforts like these can help spread cool roof benefits across densely populated neighborhoods that need cooling help most.

    As climate change drives more frequent and intense urban heat, cities have powerful tools for lowering the temperature. With some attention to what already exists and what’s feasible, they can find the right budget-conscious strategy that will deliver cooling benefits for everyone.

  • MIL-OSI Submissions: How the nature of environmental law is changing in defense of the planet and the climate

    While the dangerous effects of climate change continue to worsen, legal efforts to address a range of environmental issues are also on the rise.

    Headlines across the globe tout many of these legal actions: South Korea’s Climate Law Violates Rights of Future Generations; Ukraine is Ground Zero in Battle for Ecocide Law; Paris Wants to Grant the River Seine Legal Personhood; and Montana Court Rules Children Have the Right to a Healthy Environment, to name a few recent examples.

    As an environmental lawyer, I see that most of these suits use one of five legal strategies that have been developed over the past couple of decades. These approaches vary in terms of who is filing the lawsuit, against whom, and whether the underlying legal perspective is based on protecting human rights or the rights of the environment itself. But they all share an innovative approach to protect all life on this planet.

    1. Right to a healthy environment

    In 2022, the United Nations declared that humans have “the right to a clean, healthy and sustainable environment … essential to protecting human life, well-being and dignity.” More than 150 countries have similar declarations in their constitutions or laws, often alongside protections for other human rights, such as those to education and medical care.

    These rights are held by humans, so people can sue for alleged violations. Typically they sue one or more government agencies, whose responsibility it is to protect human rights.

    One recent case using this approach was Held v. Montana, in which a group of young people in 2024 won a lawsuit against the state of Montana for violating the state constitution’s right to a “clean and healthful environment.” The state Supreme Court agreed with the plaintiffs and struck down a law barring the consideration of climate effects when evaluating proposals for fossil fuel extraction. Similar cases have been heard in the U.S. and other countries around the world.

    2. The rights of future generations

    A legal concept called “intergenerational equity” is the idea that present generations must “responsibly use and conserve natural resources for the benefit of future generations.” First codified in international law in the 1972 Stockholm Declaration, the principle has been gaining popularity in recent decades. International organizations and national governments have enshrined this principle in law.

    Focused on humans’ rights, these laws allow people and groups to bring claims, usually against governments, for allowing activities that are altering the environment in ways that will harm future generations. One well-known case that relied on this legal principle is Future Generations v. Ministry of the Environment and Others, in which a Colombian court in 2018 agreed with young people who had sued, finding that the Colombian government’s allowance of “rampant deforestation in the Amazon” violated the pact of intergenerational equity.

    3. Government responsibility

    Another human-centered approach is the public trust doctrine, which establishes “that certain natural and cultural resources are preserved for public use” and that governments have a responsibility to protect them for everyone’s benefit.

    While the concept of “public trust” has long existed in the law, recently it has been used to bring suit against governments for their failure to address climate change and other environmental degradation. In Urgenda Foundation v. the State of the Netherlands, a Dutch court held in 2019 that the government has a responsibility to mitigate the effects of climate change due to the “severity of the consequences of climate change and the great risk of climate change occurring.” Since the decision, the Dutch government has sought to reduce emissions by phasing out the use of coal, increasing reliance on renewable energy and aiming to achieve carbon neutrality by 2050.

    Government responsibility for the public trust was also a basis of the Juliana v. U.S. case, where a group of young people sued the U.S. government for breaching the public trust by not doing enough to curb greenhouse gas emissions. The U.S. Supreme Court ultimately declined to hear an appeal of a lower court’s ruling, but the lack of a specific ruling by the nation’s highest court has given continued hope to new cases, which continue to be filed based on the same principle.

    4. Rights of nature

    The rights of nature is one of the fastest-growing environmental legal strategies of the past decade. Since Ecuador recognized the rights of Pachamama, the Quechua name for Mother Earth, in its Constitution in 2008, more than 500 laws on the rights of nature have been enacted around the world.

    The principle recognizes the legal rights of natural entities, such as rivers, mountains, ecosystems or even something as specific as wild rice. The laws that grant these rights don’t focus on humans but rather nature itself, often including language that the natural entity has the right to “exist and persist.”

    The laws then provide a mechanism for the natural entity – whether through a specific group assigned legal guardianship or other community efforts – to protect itself by filing lawsuits in court. In the 2018 Colombian case, the court found that the Amazon ecosystem has rights, which must be respected and protected.

    Similarly, in Bangladesh in 2019 the courts recognized the rights of all the country’s rivers, requiring, among other things, a halt on damaging development along the rivers that block their natural flow. The court also created a commission to serve as legal guardians of the country’s rivers.

    5. Defining a new crime: Ecocide

    In 2024, the governments of Vanuatu, Fiji and Samoa formally proposed that the international community recognize a new crime under international law. Called “ecocide,” the principle takes a nature-focused approach and includes any unlawful act committed with “the knowledge that there is a substantial likelihood of severe and either widespread or long-term damage to the environment.”

    Put another way, what genocide is to humans, ecocide is to nature. It is being proposed as an addition to the 2002 Rome Statute, which created the International Criminal Court to prosecute war crimes, genocide and crimes against humanity.

    While the idea is relatively new, in addition to the international efforts, several countries have incorporated ecocide into their laws – including Vietnam, France, Chile and Ukraine. A Ukrainian prosecutor is currently investigating the June 2023 destruction of a dam in a Russian-occupied area of the country as a potential crime of ecocide, because of the widespread flooding and habitat destruction that resulted.

    The European Union has also incorporated ecocide into its Environmental Crime Directive, which applies to all EU member countries, providing them with a mechanism to hear ecocide claims in their national courts.

    Using these ideas

    Each of these legal concepts has the potential to increase protection for the environment – and the people who live in it. But determining which strategy has the greatest chance of success depends on the details of the existing law and legal system in each community.

  • MIL-OSI Submissions: Trump has fired the head of the Library of Congress, but the 225-year-old institution remains a ‘library for all’ – so far

    Carla Hayden, the 14th librarian of Congress, who has held the position since 2016, received an unexpected email on May 8, 2025.

    “Carla, on behalf of President Donald J. Trump, I am writing to inform you that your position as the Librarian of Congress is terminated effective immediately. Thank you for your service,” wrote Trent Morse, deputy director of presidential personnel at the White House.

    White House Press Secretary Karoline Leavitt later explained that Hayden, who was the first woman, Black person and professionally trained librarian to oversee the Library of Congress, had done “quite concerning things,” on the job, including “putting inappropriate books in the library for children.”

    Democratic politicians sharply criticized Hayden’s termination, saying the firing was unjust. It was actually about Trump punishing civil servants “who don’t bend to his every will,” New York Sen. Chuck Schumer said.

    An information science scholar, I have written extensively about the history of libraries and archives, including the Library of Congress. To fully understand the role Hayden played for the past nine years, I think it is important to understand what the Library of Congress does, and the overlooked and underappreciated role it has played in American life.

    The Library of Congress’ work

    The Library of Congress is an agency that was first established, by an act of Congress, in 1800. The act provided for “the purchase of such books as may be necessary for the use of Congress at the said city of Washington, and for fitting up a suitable apartment for containing them.” Its chief librarian is appointed by the president and confirmed by the Senate.

    The library has six buildings in Washington that hold a print and online collection of nearly 26 million books, as well as more than 136 million other items, including manuscripts, maps, sheet music and prints and photographs.

    It also houses historic documents, like Thomas Jefferson’s rough draft of the Declaration of Independence and James Madison’s notes on the 1787 Constitutional Convention.

    The library is the property of the American people. Anyone over the age of 16 with a government-issued photo identification can enter its buildings and read or view its materials on-site. The Library of Congress was partially designed as a research institution to suit the needs of members of Congress, and only Congress members can borrow items from the library and take them home.

    The Library of Congress has an annual budget of about US$900 million, with a staff of 3,263. In 2024, the library’s staff helped acquire 1,437,832 million new items, issue nearly 69,000 library cards and answer more than 764,000 reference requests, among other tasks.

    The library’s deep roots

    The library has evolved alongside the U.S. itself. Five years before the Constitutional Convention of 1787, future president James Madison called for a library to provide materials to help inform Congress and its members. In 1800, President John Adams signed a bill that established the institution, which began with a $5,000 government appropriation, equivalent to more than $127,000 today.

    The library’s first collection included 152 works in 740 volumes imported from England. It occupied a space in a Washington Senate office that measured just 22 feet by 34 feet.

    The British army torched the infant library and its collection that had grown to 3,000 books in 1814, during the War of 1812. In response, former president Thomas Jefferson sold his personal collection of 6,479 books to the library, which he called “unquestionably the choicest collection of books in the U.S.

    Tragedy struck again in 1851, with a fire that incinerated two-thirds of the library’s 55,000 volumes, including most of Jefferson’s personal collection.

    The organization rebounded in the next few years, as it purchased the 40,000-volume Smithsonian library in 1866, among other new acquisitions.

    Ainsworth Spofford, the sixth librarian of Congress, boosted the library’s national image in the late 1800s when he tried to centralize the country’s patchwork copyright system.

    Spofford also successfully lobbied Congress to pass the Copyright Act of 1870, which stipulated that any party registering a work for copyright needed to deposit two copies of that work with the library.

    A growing place in American life

    As its collections burgeoned in both scale and scope in the latter part of the 19th century, the library assumed an increasingly visible role and became known by some as “the nation’s library.” By 1900, it had nearly 1 million printed books and other materials.

    The opening of a new library building in 1897, offering services to blind people with a designated reading room containing 500 raised character – or braille – books and music items, epitomized the library’s new status.

    President Theodore Roosevelt said in 1901 that the library was “the one national library of the United States” and that was “a unique opportunity to render to the libraries of this country – to American scholarship – service of the highest importance.”

    The library’s work, and global approach, continued to grow during the 20th century.

    By the late 1900s, the library held materials in more than 450 languages.

    It continued to add remarkable items to its collection, including a Gutenberg Bible, the first book printed in Europe from movable metal type, a kind of printing technology, in 1455.

    Documenting the evolution of democracy, the library also assumed stewardship of 23 presidents’ official papers, from George Washington to Calvin Coolidge, during this time frame.

    A public service

    While primarily designated a research institution for Congress, the library has also catered to a diverse range of patrons, including by mail and telephone.

    As one Science Digest writer noted in 1960, reference staff members fielded questions ranging from “What was the color of a mastodon’s eye?” to “How many words are there in the English language?” and “Could you suggest a name for twins?”

    The library’s register of copyrights received similarly diverse and even humorous inquiries. One older woman seeking to publish her poetry wrote in 1954 to request “a poetic license” to ensure her work conformed to the law.

    In the late 20th century, the library focused on a new democratic national and international mission, as it embraced a new role. Daniel Boorstin, the librarian from 1975 to 1987, termed that role a “multimedia encyclopedia.”

    A congressional resolution marking the Library of Congress’s bicentennial in 2000 noted that it was “the largest and most inclusive library in human history,” as it digitized its collections to extend its reach still further with the growth of the internet.

    As the library marks its 225th year, it continues to represent, as David Mearns, chief of the library’s manuscript division, said in 1947, “the American story.”

    A library for all

    Following Hayden’s dismissal, Trump appointed Deputy Attorney General Todd Blanche, his former personal lawyer, as acting librarian of Congress.

    Hayden has contended that her dismissal, which occurred alongside other firings of top civil servants, including the national archivist, represents a broad threat to people’s right to easily access free information.

    Democracies are not to be taken for granted,” Hayden said in June. She explained in an interview with CBS that she never had a problem with a presidential administration and is not sure why she was dismissed.

    “And the institutions that support democracy should not be taken for granted,” Hayden added.

    In her final annual report as librarian, Hayden characterized the institution as “truly, a library for all.” So far, even without her leadership, it remains just that.

  • MIL-OSI Submissions: Ozzy Osbourne’s spirit of defiance changed music forever

    Source: The Conversation – UK – By Douglas Schulz, Lecturer in Sociology and Criminology, University of Bradford

    Ozzy Osbourne’s death is not just the passing of another rock star. It marks the end of an era – the fading of a figure who helped shape an entire music genre and subculture.

    Both as a member of Black Sabbath and as a solo artist, Osbourne’s legacy lies not only in music history but how we understand performance, rebellion, and the expressive power of sound itself.

    Despite a long battle with Parkinson’s disease and several health setbacks over the years, the news of his death was a shock to the whole metal community. Just weeks before his death on July 22, Osbourne delivered his final performance with Black Sabbath in the place it all began – Villa Park in Birmingham.

    In the hours following the announcement of his death, countless bands and musicians flooded their social media channels to pay their respects.

    Osbourne’s life was a testament to reinvention, grit, and the power of artistic authenticity – going from a working-class kid in Aston to the biggest name in heavy metal, writing the soundtrack to so many people’s lives. His distinctive voice, theatrical presence, and sheer will and determination shaped heavy metal music – inspiring generations of musicians and fans.

    When Black Sabbath emerged in the early 1970s, they played a role in making rock music more menacing, grittier and heavier. The Birmingham band didn’t just turn up the amplifiers and played louder guitars – they introduced a new aesthetic. They were known for their doomy riffs and lyrics about war, madness and the occult. Osbourne, with his uncanny voice and stage presence, was at the front and centre.

    This sound was destined to become the blueprint for heavy metal. But Osbourne’s contribution went beyond his voice. He gave the genre its face, theatricality – and above all, its spirit of defiance.

    Whether he was biting off the head of a bat on stage, stumbling through reality television with absurd but relatable quotes, or delivering genre-defining performances, Osbourne embodied contradictions. He was a mix of menace and mischief, tragedy and comedy, myth and man.

    Heavy metal music has existed in tension with mainstream culture ever since its emergence in the UK in the late 1960s. It has been regarded as too aggressive, too loud, too weird. But Osbourne’s presence forced metal into the public discourse – whether through moral panics in the 1970s and ’80s, or through his television appearances in the 2000s. The Osbournes, a reality show following the family which aired on MTV, was a huge hit in the US and around the world, making Ozzy famous to a whole new audience.

    Throughout his long career, Osbourne helped shift heavy metal from the margins into the mainstream, without ever diluting its transgressive edge.

    A symbol of inspiration

    Osbourne’s stage persona carved out space for other artists to follow. His willingness to be ridiculous, to speak openly about his addictions, health struggles and family dysfunction made him oddly relatable. It is that relatability that allowed Osbourne to be metal’s court jester and elder statesman in one.

    Over time, bands like Slipknot, Ghost, Sleep Token, as well as more introspective bands like Deftones or Gojira, owe much to the groundwork Osbourne and Black Sabbath laid: a template for authenticity, theatricality, and emotional openness wrapped in spectacle and distortion. They helped define the core rhythms, riffs, themes and aesthetics that generations of metal bands followed.

    But Osbourne’s cultural influence cannot be measured only in record sales (although those were plenty), Grammy wins, or his induction into the US Rock and Roll Hall of Fame. His influence lies in how his image, sound and attitude reshaped music scenes across continents.

    In countries where metal is censored or underground, Osbourne was a symbol of resistance. In places where metal was accepted, he was the genre’s most unpredictable ambassador.

    The Prince of Darkness, as he was known, may have left the stage but his legacy will live on. His music is still looped on Tiktok videos, and memes still make rounds on social media.

    Young metal-heads will continue to emulate his style and irreverence. As long as people pick up guitars and look for a way to scream back at the world, Ozzy will be there – in spirit, in sound, and in spectacle.

    We believe in the power of research to change the world for the better. But we also understand that research needs to be shared – effectively and accessibly – if it is to have its greatest impact.

    As the Conversation UK’s specialist communications subsidiary, Universal Impact’s mission is to enable researchers to communicate their work, in a targeted way, to a wide range of different audiences. Which is why we’re currently working with Prototypes for Humanity. This Dubai-based academic forum and event promotes innovative scientific solutions and enables international research collaboration.

    In April, we blogged about how the forum was seeking applicants for its Professors’ Programme. But applications to join this year’s Prototypes for Humanity annual gathering are now open to current university students on any undergraduate or postgraduate course – as well as graduates who completed their qualifications within the past two years.

    The key is that your work potentially offers a tangible solution to a real world problem.

    That’s you? Apply now…

    Participation is free and successful applicants will showcase their innovative solutions at the Jumeirah Emirates Towers, Dubai, from November 17 to 20, 2025. Flight and accommodation costs are covered by the organiser.

    There is also a US$100,000 prize fund to help the best projects roll out in the real world – and the opportunity to connect with a wide range of potential partners, funders and collaborators.

    The evaluation criteria are threefold, stating that the successful applicants will be able to show:

    Positive impact on people, communities or the planet: Whether addressing social issues, environmental concerns, or community development, demonstrating the project’s potential positive impact will be a crucial factor.

    Rigour of academic research: We are seeking projects that demonstrate a deep understanding of the challenges addressed, and the students’ ability to propose meaningful and innovative solutions through structured research.

    Application of technology: Innovative and effective use of technology (High-tech or Low-tech) is key, whether incorporating cutting-edge advancements or utilising simple yet efficient solutions.

    More than 2,700 entries landed in The Prototypes for Humanity programme’s inbox last year. And researchers from 800 universities, many members of The Conversation’s international network, applied.

  • Doctors shouldn’t be allowed to object to medical care if it harms their patients

    Source: ForeignAffairs4

    Source: The Conversation – Global Perspectives – By Julian Savulescu, Visiting Professor in Biomedical Ethics, Murdoch Children’s Research Institute; Distinguished Visiting Professor in Law, University of Melbourne; Uehiro Chair in Practical Ethics, The University of Melbourne

    A young woman needs an abortion and the reasons, while urgent, are not medical. A United States Navy nurse at Guantánamo Bay is ordered to force-feed a defiant detainee on hunger strike.

    These very different real-life cases have one connecting thread: the question of whether a health professional can conscientiously object to carrying out a patient’s request.

    Freedom of conscience is often held up as a purely noble principle. But when it’s used to deny health care, it means a single person’s beliefs are dictating what is best for another person’s physical and mental health – which can have devastating, even fatal, results.

    In our recent book, Rethinking Conscientious Objection in Healthcare, colleagues and I conclude doctors should not be free to make medical decisions based on their personal beliefs.

    It’s not noble to refuse care

    Freedom of conscience is strongly – but not absolutely – protected under international human rights law. It is enshrined in the Universal Declaration of Human Rights.

    This principle has often been used for moral purposes: for example, to resist orders to torture or kill.

    But after researching use of conscientious objection by health professionals, I have concluded it is seriously flawed when used to deny patients health services. This is especially so when particular doctors have a monopoly on service provision, as is the case with abortion and assisted dying in many rural and regional areas of Australia.

    In Australia, doctors are allowed to conscientiously object to abortion, although nearly all states require referral to other service providers or information about how to access the relevant service.

    In practice, these laws are not enforced and sometimes disregarded.

    A doctor’s refusal can mean patients can be denied the standard of care they need, or indeed, any care at all.

    Health-care professionals are not like pacifists refusing conscription into the military, opposing something forced upon them. They freely choose health-care careers that come with obligations and with ethical stances already established by professional codes of conduct.

    People are free to hold whatever beliefs they choose, but those beliefs will inevitably close off some options for them. For example, a vegetarian will not be able to work in an abattoir. That is true for every one of us. But what shouldn’t happen is a doctor’s personal beliefs closing off legitimate options for their patient.

    4 guiding questions

    Instead of personal values, there are four key secular principles we propose that doctors should rely on when deciding how to advise patients about sensitive procedures:

    • is it legal?

    • is it a just and fair use of any resources that might be limited?

    • is it in the interests of the patient’s wellbeing?

    • is it what the patient has themselves decided they want?

    Of course, there will be times when some of these principles are in conflict – that is when it is important to apply the most crucial ones, the wellbeing of the patient and the patient’s own wishes.

    In Ireland in 2012, a young woman named Savita Halappanavar went to an Irish hospital for treatment for her miscarriage. Doctors knew there was no hope of the pregnancy surviving but refused to evacuate her uterus while there was still a fetal heartbeat, for fear of breaching Ireland’s anti-abortion laws. The result: Savita died of septicaemia at 31.

    If doctors had put the patient’s wellbeing first, they would have given her that termination, despite the law, and it would have saved her life.

    These are the principles that should have been applied to the examples above: the woman seeking an abortion for career reasons or the nurse refusing to force-feed prisoners.

    The doctor (or nurse) should ask: Is it what the patient has autonomously decided they want? Will it lead to the best outcome for both their physical and their mental health?

    If abortion will promote a woman’s wellbeing, it is in her interests. Hunger strikers should not be force-fed because it violates their autonomy.

    An unfair burden

    While doctors’ personal values are important, they should not dictate care at the bedside. Not only can this disadvantage the patient, but it places an unfair burden on colleagues who do accept such work, and must carry a disproportionate load of procedures they might find unpleasant and financially unrewarding.

    It also creates injustice. Patients who are educated, wealthy and well-connected already find it easier to access health care. Conscientious objection intensifies that unfairness in large swathes of the country because it further limits options.

    Two countries with excellent health-care systems, Sweden and Finland, do not permit conscientious objection by medical professionals.

    In Australia, it is time we do the same and strongly limit conscientious objection as a legal right for health professionals. We should also ensure those entering the discipline are prepared to take on all procedures relevant to their specialty.

    And lastly, but most importantly, we should educate them that the patient’s interests and values must always come first. An individual doctor’s sense of moral authority should not be permitted to morph into medical and moral authoritarianism.

    On July 1, astronomers spotted an unusual high-speed object zooming towards the Sun. Dubbed 3I/ATLAS, the surprising space traveller had one very special quality: its orbit showed it had come from outside our Solar System.

    For only the third time ever, we had discovered a true interstellar visitor. And it was weird.

    3I/ATLAS breaking records

    3I/ATLAS appeared to be travelling at 245,000 kilometres per hour, making it the fastest object ever detected in our Solar System.

    It was also huge. Early estimates suggest the object could be up to 20km in size. Finally, scientists believe it may even be older than our Sun.

    Davide Farnocchia, navigation engineer at NASA’s JPL, explains the discovery of 3I/ATLAS.

    Could it be alien?

    Our first assumption when we see something in space is that it’s a lump of rock or ice. But the strange properties of 3I/ATLAS have suggested to some that it may be something else entirely.

    Harvard astrophysics professor Avi Loeb and colleagues last week uploaded a paper titled Is the Interstellar Object 3I/ATLAS Alien Technology? to the arXiv preprint server. (The paper has not yet been peer reviewed.)

    Loeb is a controversial figure among astronomers and astrophysicists. He has previously suggested that the first known interstellar object, 1I/ʻOumuamua, discovered in 2017, may also have been an alien craft.

    Among other oddities Loeb suggests may be signs of deliberate alien origin, he notes the orbit of 3I/ATLAS takes it improbably close to Venus, Mars and Jupiter.

    We’ve sent out our own alien probes

    The idea of alien probes wandering the cosmos may sound strange, but humans sent out a few ourselves in the 1970s. Both Voyager 1 and 2 have officially left our Solar System, and Pioneer 10 and 11 are not far behind.

    So it’s not a stretch to think that alien civilisations – if they exist – would have launched their own galactic explorers.

    However, this brings us to a crucial question: short of little green men popping out to say hello, how would we actually know if 3I/ATLAS, or any other interstellar object, was an alien probe?

    Detecting alien probes 101

    The first step to determining whether something is a natural object or an alien probe is of course to spot it.

    Most things we see in our Solar System don’t emit light of their own. Instead, we only see them by the light they reflect from the Sun.

    Larger objects generally reflect more sunlight, so they are easier for us to see. So what we see tends to be larger comets and asteroid, especially farther from Earth.

    It can be very difficult to spot smaller objects. At present, we can track objects down to a size of ten or 20 metres out as far from the Sun as Jupiter.

    Our own Voyager probes are about ten metres in size (if we include their radio antennas). If an alien probe was similar, we probably wouldn’t spot it until it was somewhere in the asteroid belt between Jupiter and Mars.

    If we did spot something suspicious, to figure out if it really were a probe or not we would look for a few telltales.

    First off, because a natural origin is most likely, we would look for evidence that no aliens were involved. One clue in this direction might be if the object were emitting a “tail” of gas in the way that comets do.

    However, we might also want to look for hints of alien origin. One very strong piece of evidence would be any kind of radio waves coming from the probe as a form of communication. This is assuming the probe was still in working order, and not completely defunct.

    We might also look for signs of electrostatic discharge caused by sunlight hitting the probe.

    Another dead giveaway would be signs of manoeuvring or propulsion. An active probe might try to correct its course or reposition its antennas to send and receive signals to and from its origin.

    And a genuine smoking gun would be an approach to Earth in a stable orbit. Not to brag, but Earth is genuinely the most interesting place in the Solar System – we have water, a healthy atmosphere, a strong magnetic field and life. A probe with any decision-making capacity would likely want to investigate and collect data about our interesting little planet.

    We may never know

    Without clear signs one way or the other, however, it may be impossible to know if some interstellar objects are natural or alien-made.

    Objects like 3I/ATLAS remind us that space is vast, strange, and full of surprises. Most of them have natural explanations. But the strangest objects are worth a second look.

    For now, 3I/ATLAS is likely just an unusually fast, old and icy visitor from a distant system. But it also serves as a test case: a chance to refine the way we search, observe and ask questions about the universe.

  • Do countries have a duty to prevent climate harm? The world’s highest court is about to answer this crucial question

    The International Court of Justice (ICJ) will issue a highly anticipated advisory opinion overnight to clarify state obligations related to climate change.

    It will answer two urgent questions: what are the obligations of states under international law to protect the climate and environment from greenhouse gas emissions, and what are the legal consequences for states that have caused significant harm to Earth’s atmosphere and environment?

    ICJ advisory opinions are not legally binding. But coming from the world’s highest court, they provide an authoritative opinion on serious issues that can be highly persuasive.

    This advisory opinion marks the culmination of a campaign that began in 2019 when students and youth organisations in Vanuatu – one of the most vulnerable nations to climate-related impacts – persuaded their government to seek clarification on what states should be doing to protect them.

    Led by Vanuatu and co-sponsored by 132 member states, including New Zealand and Australia, the United Nations General Assembly formally requested the advisory opinion in March 2023.

    More than two years of public consultation and deliberation ensued, leading to this week’s announcement.

    What to expect

    Looking at the specific questions to be addressed, at least three aspects stand out.

    First, the sources and areas of international law under scrutiny are not confined to the UN’s climate change framework. This invites the ICJ to consider a broad range of law – including trans-boundary environmental law, human rights law, international investment law, humanitarian law, trade law and beyond – and to draw on both treaty-related obligations and customary international law.

    Such an encyclopaedic examination could produce a complex and integrated opinion on states’ obligations to protect the environment and climate system.

    Second, the opinion will address what obligations exist, not just to those present today, but to future generations. This follows acknowledgement of the so-called “intertemporal characteristics” of climate change in recent climate-related court decisions and the need to respond effectively to both the current climate crisis and its likely ongoing consequences.

    Third, the opinion won’t just address what obligations states have, but also what the consequences should be for nations:

    where they, by their acts and omissions have caused significant harm to the climate system and other parts of the environment.

    Addressing consequences as well as obligations should cause states to pay closer attention and make the ICJ’s advisory more relevant to domestic climate litigation and policy discussions.

    Global judicial direction

    Two recent court findings may offer clues as to the potential scope of the ICJ’s findings.

    Earlier this month, the Inter-American Court of Human Rights published its own advisory opinion on state obligations in response to climate change.

    Explicitly connecting fundamental human rights with a healthy ecosystem, this opinion affirmed states have an imperative duty to prevent irreversible harm to the climate system. Moreover, the duty to safeguard the common ecosystem must be understood as a fundamental principle of international law to which states must adhere.

    Meanwhile last week, an Australian federal court dismissed a landmark climate case, determining that the Australian government does not owe a duty of care to Torres Strait Islanders to protect them from the consequences of climate change.

    The court accepted the claimants face significant loss and damage from climate impacts and that previous Australian government policies on greenhouse gas emissions were not aligned with the best science to limit climate change. But it nevertheless determined that “matters of high or core government policy” are not subject to common law duties of care.

    Whether the ICJ will complement the Inter-American court’s bold approach or opt for a more constrained and conservative response is not certain. But now is the time for clear and ambitious judicial direction with global scope.

    Implications for New Zealand

    Aotearoa New Zealand aspires to climate leadership through its Climate Change Response (Zero Carbon) Amendment Act 2019. This set 2050 targets of reducing emissions of long-lived greenhouse gases (carbon dioxide and nitrous oxide) to net zero, and biogenic methane by 25-47%.

    However, actions to date are likely insufficient to meet this target. Transport emissions continue to rise and agriculture – responsible for nearly half of the country’s emissions – is lightly regulated.

    Although the government plans to double renewable energy by 2050, it is also in the process of lifting a 2018 ban on offshore gas exploration and has pledged $200 million to co-invest in the development of new fields.

    Critics also point out the government has made little progress towards its promise to install 10,000 EV charging stations by 2030 while axing a clean-investment fund.

    Although a final decision is yet to be made, the government is also considering to lower the target for cuts to methane emissions from livestock, against advice from the Climate Change Commission.

    With the next global climate summit coming up in November, the ICJ opinion may offer timely encouragement for states to reconsider their emissions targets and the ambition of climate policies.

    Most countries have yet to submit their latest emissions reduction pledges (known as nationally determined contributions) under the Paris Agreement. New Zealand has made its pledge, but it has been described as “underwhelming”. This may present a chance to adjust ambition upwards.

    If the ICJ affirms that states have binding obligations to prevent climate harm, including trans-boundary impacts, New Zealand’s climate change policies and progress to date could face increased legal scrutiny.

  • Here’s why 3-person embryos are a breakthrough for science – but not LGBTQ+ families

    Source: ForeignAffairs4

    Last week, scientists announced the birth of eight healthy babies in the United Kingdom conceived with DNA from three people. Some headlines have called it “three-person IVF”.

    The embryo uses the DNA from the egg and sperm of the intended father and mother, as well as cells from the egg of a second woman (the donor).

    This process – known as mitochondrial replacement therapy – allows women with certain genetic disorders to conceive a child without passing on their condition.

    While it’s raised broader questions about “three-parent” babies, it’s not so simple. Here’s why it’s unlikely this development will transform the diverse ways LGBTQ+ people are already making families.

    What this technology is – and isn’t

    The UK became the first country in the world to allow mitochondrial donation for three-person embryos ten years ago, in 2015.

    In other countries, such donations are banned or strictly controlled. In Australia, a staged approach to allow mitochondrial donation was introduced in 2022. Stage one will involve clinical trials to determine safety and effectiveness, and establish clear ethical guidelines for donations.

    These restrictions are based on political and ethical concerns about the use of human embryos for research, the unknown health impact on children, and the broader implications of allowing genetic modification of human embryos.

    There are also concerns about the ethical or legal implications of creating babies with “three parents”.

    Carefully and slowly considering these ethical issues is clearly important. But it’s inaccurate to suggest this process creates three parents.

    First, the amount of DNA the donor provides is tiny, only 0.1% of the baby’s DNA. The baby will not share any physical characteristics with the donor.

    While it is significant that two women’s DNA has been used in creating an embryo, it doesn’t mean lesbian couples will be rushing to access this particular in vitro fertilisation (IVF) technology.

    This technique is only used for people affected by mitochondrial disease and is closely regulated. It is not available more widely and in Australia, is not yet available even for this use.

    Second, while biological lineage is an important part of many people’s identity and sense of self, DNA alone does not make a parent.

    As many adoptive, foster and LGBTQ+ parents will attest, parenting is about love, connection and everyday acts of care for a child.

    How do rainbow families use IVF?

    Existing IVF is already expensive and medically invasive. Many fertility services offer a range of additional treatments purported to aid fertility, but extra interventions add more costs and are not universally recommended by doctors.

    While many lesbian couples and single women use fertility services to access donor sperm, not everyone will need to use IVF.

    Less invasive fertilisation techniques, such as intrauterine insemination, may be available for women without fertility problems. This means inserting sperm directly into the uterus, rather than fertilising an egg in a clinic and then implanting that embryo.

    Same-sex couples who have the option to create a baby with a sperm donor they know – rather than from a register – may also choose home-based insemination, the proverbial turkey baster. This is a cheaper and more intimate way to conceive and many women prefer a donor who will have some involvement in their child’s life.

    In recent years, “reciprocal” IVF has also grown in popularity among lesbian couples. This means an embryo is created using one partner’s egg, and the other partner carries it.

    Reciprocal IVF’s popularity suggests biology does play a role for LGBTQ+ women in conceiving a baby. When both mothers share a biological connection to the child, it may help overcome stigmatisation of “non-birth” mothers as less legitimate.

    But biology is by no means the defining feature of rainbow families.

    LGBTQ+ people are already parents

    The 2021 census showed 17% of same-sex couples had children living with them; among female same-sex couples it was 28%. This is likely an underestimate, as the census only collects data on couples that live together.

    Same-sex couples often conceive children using donor sperm or eggs, and this may involve surrogacy. But across the LGBTQ+ community, there are diverse ways people become parents.

    Same-sex couples are one part of the LGBTQ+ community. Growing numbers of trans and non-binary people are choosing to carry a baby (as gestational parents), as well as single parents who use donors or fertility services. Many others conceive children through sex, including bi+ people or others who conceive within a relationship.

    While LGBTQ+ people can legally adopt children in Australia, adoption is not common. However, many foster parents are LGBTQ+.

    When they donate eggs or sperm to others, some LGBTQ+ people may stay involved in the child’s life as a close family friend or co-parent.

    Connection and care, not DNA

    While mitochondrial replacement therapy is a remarkable advance in gene technology, it is unlikely to open new pathways to parenthood for LGBTQ+ people in Australia.

    Asserting the importance of families based on choice – not biology or what technology is available – has been crucial to the LGBTQ+ community’s story and to rainbow families’ fight to be recognised.

    Decades of research now shows children raised by same-sex couples do just as well as any other child. What matters is parents’ consistency, love and quality of care.
