Researchers warn that heatwaves and concurrent droughts of Mongolia's semi-arid plateau have increased significantly during the past two decades, with troubling implications for the future. The change also has ramifications for atmospheric conditions across the Northern Hemisphere.
Over the past 40,000 years, ice sheets thousands of kilometres apart have influenced one another through sea level changes, according to research published today in Nature. New modelling of ice sheet changes during the most recent glacial cycle by a McGill-led team demonstrates, for the first time, that during this period, changes in the Antarctic ice sheet were driven by the melting ice sheets in the Northern Hemisphere.
Twice as much freshwater is stored offshore of Hawai'i Island than previously thought, revealed a University of Hawai'i study with important implications for volcanic islands around the world. An extensive reservoir of freshwater within the submarine southern flank of the Hualālai aquifer was mapped by researchers with Hawai'i EPSCoR 'Ike Wai project, showing a way in which substantial volumes of freshwater are transported from onshore to offshore submarine aquifers along the coast of Hawai'i Island.
A team of scientists led by Berkeley Lab has designed a new material -- called ZIOS (zinc imidazole salicylaldoxime) -- that targets and traps copper ions from wastewater with unprecedented precision and speed. The technology offers the water industry and the research community the first blueprint for a water-remediation technology that scavenges heavy metal ions with a measure of control that far surpasses the current state of the art.
The 2018 eruption of Kīlauea Volcano was one of the largest volcanic events in Hawai'i in 200 years. This eruption was triggered by a relatively small and rapid change at the volcano after a decade-long build-up of pressure in the upper parts of the volcano, according to a recent study published in Nature Communications by earth scientists from the University of Hawai'i at Mānoa and U.S. Geological Survey.
Researchers are studying a tornado's song and other 'doors to danger' in an increasingly chaotic world.
Inspired by nature, researchers at The City College of New York (CCNY) can demonstrate a synthetic strategy to stabilize bio-inspired solar energy harvesting materials. Their findings, published in the latest issue of Nature Chemistry, could be a significant breakthrough in functionalizing molecular assemblies for future solar energy conversion technologies.
The current global supply of crude oil is expected to meet demand through 2050, but there may be a few more drops to squeeze out. By making use of a previously undesired side effect in oil recovery, researchers have developed a method that yields up to 20% more heavy oil than traditional methods. Tokyo University of Agriculture and Technology (TUAT) team published their results on August 24 in Energy & Fuels, a journal of the American Chemical Society.
Forensic science experts at Flinders University are refining an innovative counter-terrorism technique that checks for environmental DNA in the dust on clothing, baggage, shoes or even a passport. "This microscopic environmental trace evidence, based on soil geochemical, bacterial and fungal analysis would complement and enhance current forensic intelligence tools," lead researcher Dr Jennifer Young says in new research in Forensic Science International: Genetics.
A remote monitoring tool to help authorities manage public safety and environmental issues in recently abandoned coal mines has been developed by the University of Nottingham. The tool uses satellite radar imagery to capture millimetre-scale measurements of changes in terrain height. Such measurements can be used to monitor and forecast groundwater levels and changes in geological conditions deep below the earth's surface in former mining areas.
