There is no one prehistoric meal plan. A modern hunter-gatherer group known as the Hadza has taught researchers surprising things about the highly variable menu consumed by humans past.
Urban activities — think construction, transportation, heating, cooling and more — are major sources of greenhouse-gas emissions. Today, a growing number of cities are striving to slash their emission to net zero — here’s what they need to do.
ACs and refrigerators help keep people safe — but they also further warm the planet. Scientists are working on eco-friendlier solutions as global demand for cooling grows.
Worry over the planet’s future is taking a toll on emotional well-being, researchers say. Here’s how to cope so we don’t lose hope for our planet and for ourselves.
Eliminating this food-poisoning bacterium from poultry is tricky — not least because rapid, precise tests are still unavailable. Researchers are looking at vaccines, probiotics, prebiotics and even essential oils as ways to reduce contamination on the farm.
Where other species succumbed, the killifish survived contaminated habitats. It’s a finding that could help researchers understand environmental risk factors for humans.
More people are choosing what to eat based on where it was grown, made or created. An anthropologist looks at the myriad ways we link food to place — and whether it really could make a difference.
Are we supposed to take care of the planet or should it take care of us? Willis Jenkins explains how religion shapes the conflicting views over climate change and other environmental issues.
To understand what might be lost, ecologist Janet K. Jansson taps molecular methods to explore Earth’s underground microbes, from the permafrost to the grasslands
The only way for humanity to solve its environmental problems may be to abandon our quest for continual economic expansion. It’s time to study what a future of degrowth might look like, some researchers say.
The cryobank is a rich source of genetic knowledge of hundreds of creatures. It may one day be used to bring endangered species back from the brink and deepen the gene pool of wild populations.
The giant genomes of these struggling amphibians tell a story of outsider invasions, assault by disease and cross-species sex. A geneticist explains.
