Olfactory transmucosal SARS-CoV-2 invasion as a port of central nervous system entry in individuals with COVID-19

By |2020-12-06T17:38:17+00:00December 6th, 2020|

Abstract The newly identified severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes COVID-19, a pandemic respiratory disease. Moreover, thromboembolic events throughout the body, including in the CNS, have been described. Given the neurological symptoms observed in a large majority of individuals with COVID-19, SARS-CoV-2 penetrance of the CNS is likely. By various means, we demonstrate [...]

COVID-19 Studies Should Also Focus on Mucosal Immunity, Researchers Say

DeepMind AI cracks 50-year-old problem of protein folding

By |2020-12-06T17:38:14+00:00December 6th, 2020|

Having risen to fame on its superhuman performance at playing games, the artificial intelligence group DeepMind has cracked a serious scientific problem that has stumped researchers for half a century. With its latest AI program, AlphaFold, the company and research laboratory showed it can predict how proteins fold into 3D shapes, a fiendishly complex process that is [...]

AlphaFold: a solution to a 50-year-old grand challenge in biology

By |2020-12-06T17:38:13+00:00December 6th, 2020|

Proteins are essential to life, supporting practically all its functions. They are large complex molecules, made up of chains of amino acids, and what a protein does largely depends on its unique 3D structure. Figuring out what shapes proteins fold into is known as the “protein folding problem”, and has stood as a grand challenge in biology [...]
