Shipping noise can disturb porpoises and disrupt their mealtime
Noise from ships may disturb harbor porpoises enough to keep them from getting the food they need.

Ancient ozone holes may have sterilized forests 252 million years ago
Swaths of barren forest may have led to Earth’s greatest mass extinction.

Humans are overloading the world’s freshwater bodies with phosphorus
Human activities are driving phosphorus levels in the world’s lakes and other freshwater bodies to a critical point.

A peek into polar bears’ lives reveals revved-up metabolisms
Polar bears have higher metabolisms than scientists thought. In a world with declining Arctic sea ice, that could spell trouble.

Grapevines are more drought-tolerant than thought
Grapevines handle drought better than previously thought. This could inform irrigation management.

Life may have been possible in Earth’s earliest, most hellish eon
Heat from asteroid bombardment during Earth’s earliest eon wasn’t too intense for life to exist on the planet, a new study suggests.

Plastic pollution increases risk of devastating disease in corals
Researchers estimate about 11 billion pieces of plastic are polluting Asia-Pacific corals, raising the risk of disease at scores of reefs.

Overlooked air pollution may be fueling more powerful storms
The tiniest particles in air pollution aren’t just a health threat. They also strengthen thunderstorms, new research suggests.

Robots map largest underwater volcanic eruption in 100 years
High-resolution mapping of a 2012 underwater volcanic eruption just goes to show there’s a lot we don’t know about deep-sea volcanism.

Volume of fracking fluid pumped underground tied to Canada quakes
Study links volume of fracking fluid injected underground with hundreds of quakes in central Canada, and not the rate at which the fluids were injected.
