Is your home chilly? This might just be healthy
Feeling mildly cold (or a bit too warm) forces the body to adjust what it’s doing to maintain a healthy temperature. And that can do a body good, data now show.

Cities drive animals and plants to evolve
Biologists are finding that some species have used genetic changes to evolve — adapt — to the pollution and other stressors that they encounter in cities.

Did your burger come with a side of non-degrading pollutants?
Perfluorinated compounds pollute the environment and might harm human health. A new study shows that one place they often show up is the paper and cardboard used to package fast foods.

Teen converts water pollutant into a plant fertilizer
Too much phosphate can fuel algal growth, which can rob oxygen from the water. This can suffocate fish and other wildlife. Stefan Wan found a way to collect that pollutant, which can later be used as a farm nutrient.

Explainer: How brief can hibernation be?
Many animals frequently slow body functions and drop their temperatures — sometimes for just a day. Is that hibernation, or just torpor? Are the two even related? Scientists disagree.

Wild hamsters raised on corn eat their young alive
European hamsters raised in the lab turn into crazy cannibals when fed a diet rich in corn, new data show. The problem may trace to a shortage of a key vitamin.

Under blanket of ice, lakes teem with life
Life under frozen lakes is vibrant, complex and surprisingly active, new research finds. In fact, some plants and animals can only live under the ice. But with climate change, will that continue?
