Studies on white-tailed deer in Pennsylvania and Ontario offer evidence that the mammals are a reservoir for the virus. What are the implications for the course of SARS-CoV-2?
"Scientifically, it is highly likely that the immune response by this vaccine also can deal with the new virus variant," BioNTech CEO Ugur Sahin said Tuesday.
There are various studies looking at changes to the virus genome — and the possible impact on how the virus affects humans. Here's what we know (and don't yet know) about mutations.
It turns out you aren't simply a clone of cells from the womb. Over a lifetime, mutations create a patchwork of tissues made with pieces that have subtly different genetic signatures.
New data have confirmed major differences in mutation rates between the sexes — showing that children inherit more mutations from their dads than from their moms, says guest commentator Robert Martin.
Scientists have found a group of worms that haven't reproduced sexually for 18 million years. Normally that would be a recipe for quick extinction, but these little guys seem none the worse for wear.
Three genetic changes could be enough to make a bird flu strain that's already killing some people in China highly contagious. Are experiments with a deliberately mutated version too risky?
Researchers have long known behavior, environment and genetics play a role in cancer. A study in Science finds luck is also a major factor. Nearly two-thirds of cancer mutations arise randomly.
