Olivine May Have Given Life a Jump Start
A mineral common throughout the solar system nudges a reaction that produces sugar molecules from formaldehyde.
OneHealth, Climate Change, and Infectious Microbes
AGU and ASM welcome submissions to a joint special collection focusing on the impacts of climate change and microbes on human well-being.
Gently Down the Stream: Carbon’s Journey from Land to Sea and Beyond
Movement of carbon from land to ocean and atmosphere plays an important, but understudied, role in the global carbon cycle.
Rivers Are Warming Up and Losing Oxygen
Researchers used deep learning to fill in the gaps of “patchy” water quality data, revealing decades-long trends toward warmer and less oxygenated rivers that could have worrisome consequences.
Protein Powder Makes Ice Crystals Flower
Dust from Alaska is particularly effective at forming ice crystals because it contains biological components, researchers believe. The finding has implications for cloud physics and our planet’s climate.
Our Evolving Understanding of Biological Carbon Export
The array of processes and organisms that make up the biological carbon pump has immense influence on Earth’s carbon cycle and climate. But there’s still much to learn about how the pump works.
More Than Half the World’s Ocean Surface Is Getting Greener
Advances in data analysis help researchers spot shifting ocean colors, which could be associated with climate change.
Air Flow Dynamics in Wet Soils: Challenges and Knowledge Gaps
Modeling air flow in wet porous media relies on quantifying the combined role of fluid and media properties and flow dynamics on the microscale displacement mechanisms and macroscale unstable flow.
The Science We Need to Assess Marine Carbon Dioxide Removal
As companies begin selling credits for marine carbon dioxide removal in largely unregulated marketplaces, scientists must develop standards for assessing the effectiveness of removal methods.
