What Tumbling Asteroids Tell Us About Their Innards
Data from the Gaia space observatory reveal that many slowly spinning asteroids rotate chaotically. A new theory links that chaos to their inner structure and history.
As CO2 Levels Rise, Old Amazon Trees Are Getting Bigger
New data show resilience among the rainforest’s giants, though scientists warn that nutrient limits and rising heat could end the trend.
Are “Day Zero Droughts” Closer Than We Think? Here’s What We Know
A new study warns that day zero droughts—when reservoirs fail to supply taps—could become common within this decade.
Satellite Data Reveal Changing Lakes Under Antarctic Ice
Radar altimetry observations have pinpointed 85 active subglacial lakes, shedding light on how water moves beneath the Antarctic Ice Sheet.
Fire, Not Deforestation, Is Now the Amazon’s Biggest Carbon Emitter
Forest degradation in the Amazon increased by 400% in 2024. It was largely driven by wildfires during the forest’s worst fire season in more than 20 years.
Marine Heat Waves Slow the Ocean’s Carbon Flow
When plankton find themselves in hot water, organic matters stalls at the surface and disrupts transport of carbon to the deep ocean.
The Role of a Ditch in the Matrix
These constructed waterways are often a “no-man’s-land” between terrestrial scientists and limnologists. But ditches’ role in transport, agriculture, biodiversity, greenhouse gas emissions, and even archaeology means it’s time to take a closer look.
In Arctic Soils, Methane-Eating Microbes Just Might Win Out over Methane Makers
Methanotrophs, including those that capture methane from the air, seem to outcompete methanogens in dry environments, a new study shows.
REDD+ Results and Realities
A new study examines the efficacy of REDD+ projects in reducing deforestation and raises questions about the carbon credits the initiative relies on.
