This week’s top stories of the week include:
0:15 Can VR help calm surgery patients? — Doctors at the Mayo Clinic in Minnesota gave patients a set of virtual reality (VR) goggles and offered them a 10-minute ‘nature experience’. The clinic ran a trial on 100 patients, giving 50 a tablet and 50 a headset. Self-reported anxiety scores fell with both but more with the VR headset.
3:34 NY makes composting compulsory — Since 1 April, New Yorkers have had to separate food waste for recycling or face a fine of up to $300. It’s part of the city’s efforts to tackle climate change. The food waste is either composted and turned into fertilizer or emptied into a ‘biodigester’ where it emits biogas that’s used to generate renewable energy.
3:34 This robot finds people in rubble — It has an inflatable tube which can flex around corners and squeeze through narrow passages. An operator controls the tube with a joystick it has a camera and sensors at its tip, which help draw a 3D map of ‘void spaces’ and plot an entry route for emergency teams.
5:16 Space scanner maps remote forests — The world’s forests are a vital carbon sink but deforestation and degradation are eroding their storage capacity. The 1.25-tonne Biomass probe was built by Airbus and will orbit 666 km above the planet for several years, measuring and tracking changes in forests across Asia, Africa and South America.
