Understanding Tremors Through Tree Rings
Researchers look to carbon isotopes and cell-level wood anatomy to understand how seismic-induced changes in water availability affect tree growth.
Shedding Light on Microbial Communities in Deep Aquifers
Researchers use a packer system to study the microbial communities living in waters sampled from deep, uncontaminated peridotite aquifers.
Researchers Zero In on Methane Released from Reservoirs
Using new methods, researchers can estimate how much methane is released each day from reservoirs—an important step in estimating global methane emissions.
Phytoplankton as Emitters of Greenhouse Gases
Phytoplankton remove carbon dioxide from the atmosphere; a new study reveals that marine phytoplankton can also produce greenhouse gases when exposed to ultraviolet radiation.
Earthly Lava Tubes May Offer Insights into Extraterrestrial Life
New research finds that Actinobacteria in lava caves fix carbon and survive independent of surface inputs, offering a fresh perspective in the search for life beyond Earth.
Minimal Evidence of Permafrost Carbon in Siberia’s Kolyma River
New research finds that Arctic rivers currently transport limited permafrost-derived dissolved organic carbon, which has implications for understanding the region’s changing carbon cycle—and its potential to accelerate climate change.
Does the Priming Effect Happen Underwater? It’s Complicated
A new meta-analysis finds evidence that adding fresh organic material can increase decomposition rates, but when and why that happens remain unclear.
Multicellular Algae Discovered in an Early Cambrian Formation
A new study describes eukaryotic organisms found organized in a cortex-medulla pattern in southern China’s Kuanchuanpu Formation.
