Bioengineers design a new plant to purify air faster than nature
Neoplants has bioengineered a pothos plant that removes 30 times more pollutants from the air than a regular houseplant.
How much CO2 can the world emit while keeping warming below 1.5°C and 2°C?
Researchers estimate how much more CO2 we can emit to keep temperatures below 1.5°C and 2°C to combat climate change.
Light may cause water to evaporate (even without heat)
MIT researchers propose a new phenomenon that causes to water evaporate without heat. They call it the “photomolecular effect.”
Green shipping picks up speed
The shipping industry aims to get to net-zero emissions by 2050. Can novel fuels, wind power and coordination on a global scale get it there?
MIT design would harness 40 percent of the sun’s heat to produce clean hydrogen fuel
Engineers hope to produce totally green, carbon-free hydrogen fuel with a new, train-like system of reactors driven by the sun.
Cleaning up one of the world’s most commonly used substances
C-Crete has created a more sustainable cement binding material that could significantly reduce the industry’s CO2 emissions.
Study: ancient technique holds thousands of tons of carbon, sequestered over centuries
"Dark earth" holds thousands of tons of carbon, sequestered over centuries by indigenous practices, a new study suggests.
Researchers brew a stronger concrete using — coffee?
Researchers and engineers from RMIT University made concrete 30% stronger in the lab by incorporating aggregates made from coffee grounds.
