The unexplored region of the atmosphere that could help predict climate change

About 17 kilometers above the Earth's surface, the first layer of the atmosphere meets the second one. At a boundary called the tropopause, the troposphere ends and the stratosphere begins. Straddling this interface, for about five kilometers on either side, is a band of the atmosphere labeled, matter-of-factly, the "upper troposphere/lower stratosphere"—the UTLS.

Seismic study reveals key reason why Patagonia is rising as glaciers melt

The icefields that stretch for hundreds of miles atop the Andes mountain range in Chile and Argentina are melting at some of the fastest rates on the planet. The ground that was beneath this ice is also shifting and rising as these glaciers disappear. Geologists have discovered a link between recent ice mass loss, rapid rock uplift and a gap between tectonic plates that underlie Patagonia. from Phys.org - latest science and technology news stories https://ift.tt/j1h2ds5

New method to detect and visualize sperm cells recovered from forensic evidence

One of the most valuable forms of forensic evidence in cases of male-perpetrated sexual assault is the presence of semen, either in the form of stains left behind on items or on swabs collected from victims after an offense. To confirm that semen is present, suspected stains are examined under a microscope to see if any sperm cells are visible. from Phys.org - latest science and technology news stories https://ift.tt/2XBwacB
