Seven emerging technologies that could help to mitigate the most devastating effects of climate change.
Features
Ingenuity makes its first controlled flight on Mars
NASA makes history with the first demonstration of controlled flight on another planet.
Oxygen biosignature alone does not indicate life on other planets
Oxygen is a promising exoplanet biosignature, but several scenarios exist in which a lifeless, rocky planet could evolve to have non-biological oxygen in its atmosphere.
Green-sky science aims to bring us closer to net-zero aviation
The race is on to scale down the cost of sustainable aviation fuel production technologies and scale up production capacity.
Does responsible climate leadership include research into solar geoengineering?
Very little is known about the effects of solar geoengineering interventions, and many researchers agree that research as well as deployment should be carefully governed.
Building new reservoirs can have unexpected consequences on water security
Any discussion about the role of new reservoirs must focus on the creation of new unsustainable demand.
Researchers develop hydrogel to improve spinal cord repair after injury
A hydrogel loaded with drugs to simultaneously regenerate nerve tissues and blood supply shows promise for promoting recovery after spinal cord damage.
Even without a brain, metal-eating robots can still search for food
The “metal-eating” robot can follow a metal path without using a computer or needing a battery.
A spotlight on robots helps them turn “feeling” into movement
Researchers recreate the somatic nervous system in robots, allowing them to convert feeling into movement under different stimuli.
A natural way of turning off the carbon dioxide tap, California style
A new report outlines in quantitative detail the range of options, trade-offs, and costs to guide future policies in achieving carbon neutrality by 2045.
