Coral fossils show Southern Ocean current sensitive to wind conditions Washington (UPI) Dec 31, 2019
Scientists knew the Antarctic Circumpolar Current, a cold current circling through the Southern Ocean, is driven by winds, but until now scientists weren't sure of its stability.
New analysis of fossil coral skeletons suggests the ocean current is especially sensitive to winds, and that changes in the current influence the exchange of CO2 between the Southern Ocean and the atmosphere. / ... more

Creating a nanoscale on-off switch for heat Pittsburgh PA (SPX) Dec 19, 2019
Polymers are used to develop various materials, such as plastics, nylons, and rubbers. In their most basic form, they are made up of many of identical molecules joined together over and over, like a chain. If you engineer molecules to join together in specific ways, you can control the characteristics of the resulting polymer.
Using this method, Sheng Shen, an associate professor of mechan ... more
