Warmer summer and fall seasons and fewer winter freeze-thaw events have led to changes in the relative numbers of different types of bugs in the Arctic, says Amanda Koltz, a postdoctoral fellow in Arts & Sciences. The study relies on the longest-standing, most comprehensive data set on arctic arthropods in the world today: a catalogue of almost 600,000 flies, wasps, spiders and other creepy-crawlies collected at the Zackenberg field station on the northeast coast of Greenland from 1996-2014.
New research gives precise look at underground CO2 abatement process
|
Injecting carbon dioxide deep underground into basalt flows holds promise as an abatement strategy. Now, new research by scientists at Washington University in St. Louis sheds light on exactly what happens underground during the process, illustrating precisely how effective the volcanic rock could be in trapping and converting CO2 emissions.
Young Hispanic men may face greatest risk from police shootings, study finds
|
The police shooting earlier this month of Stephon Clark in his grandmother’s Sacramento backyard has renewed protests over officer-involved deaths of unarmed black men, but research led by Washington University in St. Louis suggests young Hispanic men may face an even greater risk of being killed by police, especially in mixed-income neighborhoods with large Latino populations.
