Scientists Uncover New Clues About the Climate and Health Impact of Atmospheric Particles
Peering inside common atmospheric particles is providing important clues to their climate and health effects, according to a new study by University of British Columbia chemists.
El Niño Increases Seedling Mortality Even in Drought-Tolerant Forests
A long-term study finds that seedling mortality increased when severe and prolonged drought occurred in Southeast Asian seasonally dry tropical forests, which are deemed more drought-tolerant than tropical rainforests.
Study Shows Hazardous Herbicide Chemical Goes Airborne
“Dicamba drift” — the movement of the herbicide dicamba off crops through the atmosphere — can result in unintentional damage to neighboring plants.
New Colgate Research Shows Antarctic Summer Thaw Starts Earlier, Ends Later than Previously Believed
New research from Colgate University changes our understanding of seasonal thawing in parts of Antarctica, as scientists have learned that summer thawing occurs nearly a month earlier, and stays thawed for a full two months longer, than previously believed.
Two Major Meteorite Impacts Reveal New Insights About the Surface of Mars
Following two large meteorite impacts on Mars, near-surface seismic waves have been recorded for the first time on a planet other than Earth.
