Loss of Smell and Taste Reported as Early Symptoms of COVID-19

Posted: 31 Mar 2020 12:42 PM PDT

Symptoms of COVID-19, the respiratory disease caused by the SARS-CoV-2 coronavirus, typically include a dry cough, fever and shortness of breath. But evidence is beginning to emerge from other countries and now from the UK that sudden loss of smell (also known as anosmia or hyposmia) — and in some cases, taste — is an […]
Early Mars Had Multiple Water Sources, New Study Shows

Posted: 31 Mar 2020 10:48 AM PDT

An analysis of two Martian meteorites — Northwest Africa (NWA) 7034 and Allan Hills (ALH) 84001 — shows that Mars likely received water from at least two vastly different sources early in its history; the variability implies that Mars, unlike Earth and the Moon, never had a global ocean of magma. “These two different sources […]
Newly-Synthesized Peptide Could Disarm SARS-CoV-2 Coronavirus

Posted: 31 Mar 2020 08:32 AM PDT

Chemists at the Massachusetts Institute of Technology (MIT) have chemically synthesized a new peptide (a short protein fragment) that can bind to part of SARS-CoV-2’s spike protein, a key protein responsible for getting the virus into mammalian cells, potentially disarming it. “We have a lead compound that we really want to explore, because it does, […]
Scientists Decode Genome of Sterlet Sturgeon

Posted: 31 Mar 2020 07:48 AM PDT

An international team of researchers from the United States and Europe has produced the first high-quality genomic sequence for the sterlet (Acipenser ruthenus), a small species of sturgeon from Eurasia. Sturgeons are among the oldest species on Earth in terms of evolutionary history. They are the ancestors of more than 30,000 species of bony fish […]
ALMA Uses Cosmic Lens to Capture Disturbed Gas Clouds in Distant Quasar

Posted: 31 Mar 2020 05:33 AM PDT

By combining the power of strong gravitational lensing with the capability of the Atacama Large Millimeter/submillimeter Array (ALMA), a team of astronomers from Japan and Taiwan imaged disturbed gaseous clouds in a distant quasar called MG J0414+0534; the researchers also found that the disruption is caused by supermassive black hole jets. “It is commonly known […]
