Plastic trash rides ocean currents to the Arctic
Ocean currents can carry plastic trash far from the cities that shed it. Some plastic debris has made it all of the way to the Arctic Ocean, new data 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.

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?

Food-like smell on plastic may lure seabirds to eat it
When plastic smells like supper, seabirds and other animals can be fooled into thinking it is food.

Ocean of the future may make shrimp small and colorful
Carbon dioxide released into the air can end up in the ocean, making it more acidic. A teen showed that this acidification could shrink shrimp and make them more colorful.

Teachers talk about climate change, and kids are listening
Teachers may help convince students that climate change is real. But when it comes to what’s behind that change, many kids appear to rely on more than those educators.

Algae embedded in sea ice drive the Arctic food web
Scientists traced where zooplankton in the Arctic get their energy from. Many open ocean species rely on algae found in sea ice, which is disappearing.

Something in plastics may be weakening kids’ teeth
The body can confuse some pollutants for a natural hormone. Researchers in France now find such pollutant exposures in childhood may lead cells to make defective tooth enamel.
