Analyze This: Climate change could make food less healthy
Levels of important nutrients are lower in crops exposed to high levels of carbon dioxide, a greenhouse gas. How high? Try levels expected to be typical 30 years from now.

Doctors and scientists around the world are scouring the environment for the elusive cause of Kawasaki disease, a harmful childhood illness.
- Environment
Trees can make summer ozone levels much worse
The greenery can release chemicals into the air that react with combustion pollutants to make ozone. And trees release more of those chemicals where it gets really hot, a new study finds.

Popular pesticide may harm bee flight
In a lab experiment, honeybees flew sluggishly after eating pesticide-tainted food.

Cool Jobs: Doing real science in virtual worlds
Virtual reality isn’t just for gamers. Scientists are using VR technology to tackle real-world problems.

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.

Cleaning up water that bees like to drink
Plant roots suck up pesticides used on soils, then release them into water that can seep from their leaves. This is a sweetened water that bees love to sip. A teen figured out how to remove most of the pesticide with bits of charcoal.

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.
