Researchers in Spain have found an efficient way to convert human waste into clean, renewable hydrogen fuel—and cut carbon emissions of wastewater treatment plants.
The first evidence of tool-using skunks was gathered not by biologists, but by a nature-loving citizen with a motion-activated camera. How much more might be discovered if scientists harnessed the richness of these amateur observations?
Investors are increasingly demanding that corporations disclose the likely impacts of climate change on their business and make plans to address them. But so far, what companies have come up with is largely inadequate to the scale of the challenge.
The quantity of fecal waste from humans and livestock is growing—and with it, the threat to human and environmental health. But on the flipside, a study considers how we could benefit from all this waste.
New catalysts made from abundant and inexpensive materials could lead to a commercially viable way to convert carbon dioxide into plastics and other useful products.
Where political power once belonged to a few people, it’s now shared by many. What would it mean to expand political representation even further?
When it comes to mimicry, climate change isn't a story of simple winners and losers. The relationships human actions are disrupting are complex and subtle.
The farms that produce our food may be much littler than we think, a new global mapping study reveals.
