A supernova could have sent cosmic rays hurtling at Earth muratart/Shutterstock An exploding star may have sent cosmic shrapnel flying to hit Earth 10 million years ago, and astronomers have now narrowed down the most likely culprits behind this interstellar incident. Earlier this year, Dominik Koll at the Helmholtz-Zentrum Dresden-Rossendorf in Germany and his colleagues…

Beneath our feet, an invisible world of electron exchanges quietly drives the chemistry that sustains ecosystems, controls water quality, and even determines the fate of pollutants. A new review published in Environmental and Biogeochemical Processes sheds light on how electrons travel through soils and sediments across surprisingly long distances — sometimes spanning centimeters to meters…

The bumpy snailfish is one of three new species of deep-sea snailfish described by MBARI collaborators at SUNY Geneseo. MBARI’s advanced underwater technology is revealing the remarkable species that thrive in the deep sea. In 2019, MBARI researchers encountered an unfamiliar pink snailfish swimming just above the seafloor. New research from MBARI collaborators has confirmed…

A sticky, toxic by-product that has long plagued renewable energy production may soon become a valuable resource, according to a new review published in Biochar. When biomass such as crop residues, wood, or other organic matter is heated to produce clean energy and biochar, it also generates a thick liquid known as bio-tar. This tar…

We’ve all heard the story: biochar cleans water by adsorbing pollutants — trapping them like a sponge. Or, in fancier setups, it acts as a catalyst to help oxidants like hydrogen peroxide break down toxins. But Dr. Gao’s team asked a bold question: What if biochar can degrade pollutants all by itself? Turns out —…
