Polar bears swim for days as sea ice retreats
Melting sea ice is forcing polar bears to swim long distances — up to nine days in one case. Such long treks may be more than the bears can handle.

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.

Cool Jobs: Getting to know volcanoes
It’s too hot to explore the insides of a volcano. These scientists examine their lava, their low-frequency rumblings and their ‘vog’.

Pollen can become bee ‘junk food’ as CO2 rises
Increasing levels of the greenhouse gas are changing diminishing the food value of pollen, bees’ only source of protein.

This microbe thinks plastic is dinner
The bacterium Ideonella sakaiensis chows down on one type of polluting plastics. That means it could become helpful in cleaning up environmental waste.

Carbon dioxide could explain how geysers spout
A new study overturns 150 years of thinking about Yellowstone’s geysers. Carbon dioxide, not just hot water, may be driving those spectacular eruptions.

Particles in air help fatten clouds’ water droplets
Making their own clouds has shown scientists how the fattest water droplets form. Understanding this could lead to better forecasts of climate change.

Quake risk in some central states rivals California’s
Risks of tremors in some central U.S. states are as high as those in quake-prone California. The reason: waste fluids from oil and gas drilling.
