How the coronavirus multiplies its genetic material

When someone becomes infected with the novel coronavirus SARS-CoV-2, the pathogen proliferates rapidly in the cells of the infected person. To do so, the virus has to multiply its genetic material, which consists of a single long RNA strand. This task is performed by the viral "copy machine," the so-called polymerase. Researchers led by Patrick Cramer at the Max Planck Institute for Biophysical Chemistry in Göttingen, Germany, have now determined the 3-D structure of the corona polymerase. This makes it now possible to investigate how antiviral drugs such as remdesivir—which blocks the polymerase—work, and to search for new inhibitory substances.

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
