Seven emerging technologies that could help to mitigate the most devastating effects of climate change.
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.
Researchers chill antimatter for the first time
By cooling antimatter to absolute zero, physicists may finally be able to answer questions that could fundamentally alter our understanding of the universe.

This method of purification under natural sunlight opens a new paradigm in clean water production using renewable solar energy.
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.
“Greening” brown ammonia no longer looks like a pipe dream
A recent advance in the Haber-Bosch production of ammonia increases conversion beyond the maximum allowed in the current industrial process.
How do you sample blood in a non-invasive way?
Graphene-based biosensors incorporated in arrays of microneedles are emerging as an alternative to hypodermic needles and could be the next generation of blood sampling devices.
Today’s green investment is tomorrow’s emission reduction — models must grasp this
