Common water pollutants hurt freshwater organisms
The germ killers we use and the drugs we take don’t just disappear. They can end up in the environment. There they can harm aquatic organisms, three teens showed.

Breathing very dirty air may boost obesity risk
Breathing dirty Beijing air made rats heavier and less healthy than rats breathing clean air. Scientists now worry such polluted air may do the same thing to people.

Not so sweet: Fake sugar found at sea
Sucralose — sold in stores as Splenda — has begun turning up in seawater. This raises concern about the fake sweetener’s impacts on the environment.

Powered by poop and pee?
Scientists are developing methods to not only remove human waste from wastewater, but also to harness the energy hidden within it.

Olive oil untangles plastic
Vegetable oils can make plastic fibers stronger. And the process is safer and better for the environment than other detanglers.

Using dolphins to find unknown ocean pollutants
Long-lasting pollutants may threaten marine mammals and human health. To find those pollutants, scientists are sampling blubber, then running the fatty material through new types of tests.

Arctic ice travels fast, carrying pollution
Climate change is melting old sea ice in the Arctic. Now, younger, thinner ice is migrating far and fast, taking pollutants with it.

Profile: A human touch for animals
Temple Grandin uses her own autism to understand how animals think. The animal scientist is famous for fostering the humane treatment of livestock.

Wildlife forensics turns to eDNA
Environmental DNA, or eDNA, tells biologists what species have been around — even when they’re out of sight or have temporarily moved on.

Table salt and shellfish can contain plastic
Bits of plastic have turned up in sea salts purchased in Chinese supermarkets. The finding suggests all sea salts may be similarly tainted. Shellfish too.

Plastic trash travels up to Arctic waters
Bags, fishing rope and other tiny bits of plastic are now polluting Arctic waters, posing threats to area wildlife.
