When the variant now known as omicron first appeared on a global database of coronavirus genomic sequences, scientists were stunned. This was the weirdest creature they’d seen to date. It had an ...

Add Yahoo as a preferred source to see more of our stories on Google. Scientists are concerned about the number of mutations in the new Omicron variant. The mutations might cause the variant to evade ...

An array of different mutations or combinations of mutations may help the Omicron variant of SARS-CoV-2 escape immune responses or therapeutic antibodies, according to a study published today in eLife ...

The rapid spread of the delta variant is raising concerns among scientists that the coronavirus could mutate into more transmissible or deadlier strains. The fresh fears come as the U.S. vaccination ...

In a recent study posted to the bioRxiv* pre-print server, a team of researchers investigated P323L in RNA polymerase (NSP12) and D614G in the spike (S) protein of severe acute respiratory syndrome ...

Researchers have identified the highly prevalent, specific mutations that are causing the Omicron variant's high rate of infection. The findings help explain how the new variant can escape ...

Mutations can work together to make a virus more fearsome, but they can also cancel one another out. This phenomenon, called epistasis, is why scientists are reluctant to speculate on Omicron. By ...

Most of the recently risen coronavirus variants of interest or concern -- delta, kappa, epsilon, iota and lambda -- are universally carrying a mutation in amino acid L452 of the Spike protein that ...

A newly-discovered mutation of the delta variant is under investigation in the U.K. There are worries that it could make the virus yet more transmissible, and could possibly undermine Covid-19 ...
