Global death toll from COVID-19 reaches 1 million. The global death toll from COVID-19 hit 1 million Monday, less than a year since the new disease was first reported in central China before spreading to Europe, then rocking the U.S. President Donald Trump announced a plan to distribute 150 million rapid tests, which one expert called "Inadequate.'' In what was once the epicenter of the virus, New York reported an uptick in cases over the weekend, seeing its first day with more than 1,000 new cases for the first time since June. Many of the new cases are centered around southern portions of the state and in New York City. Ref. USAToday.
Nitric oxide a possible treatment for COVID-19, study finds. Researchers have found that an effective way of treating the coronavirus behind the 2003 SARS epidemic also works on the closely related SARS-CoV-2 virus, the culprit in the ongoing COVID-19 pandemic. The substance concerned is nitric oxide (NO), a compound with antiviral properties that is produced by the body itself. Source 1g.
Letter from leading researchers urges terminology update, shift in COVID-19 guidance. Experts with leading research institutions across the United States are urging that researchers across disciplines must converge to deliver clear public health guidance about how SARS-CoV-2 is spread in the air.

Hot or cold, weather alone has no significant effect on COVID-19 spread. New research is adding some clarity on weather's role in COVID-19 infection, with a new study finding that temperature and humidity do not play a significant role in coronavirus spread. Source 3m.
Virus that causes COVID-19 puts a plug in cellular defenses. One of the novel coronavirus' most insidious tricks is that it can block the ability of cells to produce protective proteins without hindering its own ability to replicate. A new study reveals how it does it. Source 3o.
Scientists get the most realistic view yet of a coronavirus spike's protein structure. A new study, done on a mild-mannered relative of the virus that causes COVID-19, paves the way for seeing more clearly how spike proteins initiate infections, with an eye to preventing and treating them.

Large study finds higher burden of acute brain dysfunction for COVID-19 ICU patients. COVID-19 patients admitted to intensive care in the early months of the pandemic were subject to a significantly higher burden of delirium and coma than is typically found in patients with acute respiratory failure. A new study finds that choice of sedative medications and curbs on family visitation played a role in increasing acute brain dysfunction for these patients. Source 9f.
