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.

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.

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.

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.

Satellites show how a massive lake in Antarctica vanished in days
Within six days, an Antarctic lake with twice the volume of San Diego Bay drained away, leaving a deep sinkhole filled with fractured ice.

Why planting tons of trees isn’t enough to solve climate change
Massive projects need much more planning and follow-through to succeed – and other tree protections need to happen too.

How Romanesco cauliflower forms its spiraling fractals
By tweaking just three genes in a common lab plant, scientists have discovered the mechanism responsible for one of nature’s most impressive fractals.
