Hidden within African diamonds, a billion-plus years of deep-earth history

(Earth Institute at Columbia University) A team has come up with a way to solve two longstanding puzzles: the ages of individual fluid-bearing diamonds, and the chemistry of their parent material. The research has allowed them to sketch out geologic events going back more than a billion years–a potential breakthrough not only in the study of diamonds, but of planetary evolution.

Climate finance key to stem global warming, ST Editorial News & Top Stories – The Straits Times

United States President Joe Biden’s recent climate summit generated much-needed headlines and focused attention on the urgency to tackle climate change even if the coronavirus pandemic continues to top most governments’ agendas. The US, Japan and Canada announced more ambitious…

Archaeologists pinpoint population for the Greater Angkor region

(University of Oregon) Long-running archaeological research, boosted by airborne lidar sensing and machine-learning algorithms, finds that Cambodia’s Greater Angkor region was home to 700,000-900,000 people. The new estimate, made possible by a study designed at the University of Oregon, is the first for the entire 3,000-square-kilometer low-density region.

Physicists describe new type of aurora

(University of Iowa) The famed northern and southern lights have been studied for millennia, but they still hold secrets. In a new study, physicists led by the University of Iowa describe a new phenomenon they call “diffuse auroral erasers,” in which patches of the background glow are blotted out, then suddenly intensify and reappear.

Aluminum may affect climate change by increasing ocean’s carbon sink capacity – EurekAlert

Aluminum may affect climate change by increasing ocean’s carbon sink capacity

(Chinese Academy of Sciences Headquarters) Researchers from the South China Sea Institute of Oceanology (SCSIO) of the Chinese Academy of Sciences and their collaborators found that adding a small amount of aluminum to achieve concentrations in the 10x nanomolar range can increase the net fixation of CO2 by marine diatoms and decrease their decomposition, thus improving the ocean’s ability to absorb CO2 and sequester carbon at deep ocean depths.

New GSA Bulletin articles published ahead of print in April

(Geological Society of America) The Geological Society of America regularly publishes articles online ahead of print. For April, GSA Bulletin topics include multiple articles about the dynamics of China and Tibet; the Bell River hypothesis that proposes that an ancestral, transcontinental river occupied much of northern North America during the Cenozoic Era; new findings in the climatic history during one of Earth’s coldest periods: The Late Paleozoic Ice Age; and the age an nature of the Chicxulub impact crater.
