Across 28,800 prompts, models were 7.5 times more likely to advise “stay the course” than “change,” even when the status quo is anti-climate.
The synthetic fertilizers behind the Green Revolution come at a steep climate cost. A sunlight-powered purple microbe just matched them in a 2-year field trial.
In a first, researchers realistically calculated how solar farms in the Gobi Desert improve air quality in northern Chinese cities
The same proteins that keep a frozen pint smooth also make its fat hard to recover. A research team found an inexpensive way around the problem.
In a bid to cool people, not rooms, engineers made a printable fabric that turns body motion into electrical signals that switch on cooling and heating when you need it.
Frozen food worldwide is still kept at −18°C (0°F). Raising that by just three degrees could avoid 17 million tons of emissions a year, and an 18-month study found most foods stay safe and tasty.
Flying behind commercial jets, a team pinpointed the exact combination of fuel and engine technology that cuts both soot and the contrails warming the planet.
Scientists expected their artificial floating wetland to help only after cleaning the water. Instead, greenhouse gas emissions dropped months earlier, and nobody is sure exactly why.
Researchers ran the numbers on a worldwide sustainable-diet transition—and found a food system that looks nothing like today’s.
