Compared with the very first sequences of the virus that causes Covid-19, it has 58 changes to amino acids in its spike protein, according to Dr. Jesse Bloom, who studies the molecular structure ...

SARS-CoV-2, the virus that causes COVID-19, got its name based on its genetic structure. This is how all viruses are named. SARS-CoV-2 is genetically similar to the virus that led to the SARS ...

This new raft of subvariants is the inevitable consequence of the virus trying out new mutations in its spike protein – a structure which is essential for Covid-19's ability to enter human cells ...

Knowing the crystal structure of this "doorway" protein, says Fraser, is key to finding helpful drugs to stop coronavirus and influenza viruses, because it is very similar to other important proteins in the human body. "Many of the important proteins for ...

Some vaccines use a virus that has been engineered to be harmless to ferry a gene from the coronavirus into cells ... charts and diagrams that provide greater depth and context to stories over ...

But the specific pathways by which the virus does so are ... people before and after their COVID-19 infections show shrinkage of brain volume and altered brain structure after infection.
