50 years ago, scientists developed self-destructing plastic

In the 1970s, scientists developed plastic that could quickly break down when exposed to light. But that didn’t solve the world’s pollution problems.

A new book reveals stories of ancient life written in North America’s rocks

In ‘How the Mountains Grew,’ John Dvorak probes the interlinked geology and biology buried within the rocks of North America.

Greece’s Santorini volcano erupts more often when sea level drops

During past periods of lower sea levels, when more of Earth’s water was locked up in glaciers during ice ages, the Santorini volcano erupted more.

Dinosaur-killing asteroid may have made Earth’s largest ripple marks

A tsunami created by the Chicxulub impact could have formed giant ripples found in rock under Louisiana, a new study finds.

A stunning visualization of Alaska’s Yukon Delta shows a land in transition

Water and ice helped form the Yukon River’s delta. Now, climate change is reshaping it.

Paleontology

3.42-billion-year-old fossil threads may be the oldest known archaea microbes

The structure and chemistry of these ancient cell-like fossils may hint where Earth’s early inhabitants evolved and how they got their energy.

How intricate Venus’s-flower-baskets manipulate the flow of seawater

Simulations show that a deep-sea glass sponge’s intricate skeleton creates particle-trapping vortices and reduces the stress of rushing water.

Microbes

Missing Antarctic microbes raise thorny questions about the search for aliens

Scientists couldn’t find microbial life in soils from Antarctica, hinting at a limit for habitability on Earth and other worlds.

Animals

Climate change may be leading to overcounts of endangered bonobos

A changing climate in Congo is affecting how scientists count bonobos’ nests, possibly skewing estimates of the great ape population, a study suggests.

Mixing trees and crops can help both farmers and the climate

Agriculture is a major driver of climate change and biodiversity loss. But integrating trees into farming practices can boost food production, store carbon and save species.

Climate

Hurricanes may not be becoming more frequent, but they’re still more dangerous

A new study suggests that there aren’t more hurricanes now than there were roughly 150 years ago.

The first step in using trees to slow climate change: Protect the trees we have

In all the fuss over planting trillions of trees, we need to protect the forests that already exist.
