This work shows how an ecosystem evolved and recovered after catastrophe, but it took millions of years. That should really give us pause because we can’t wait that long.
Growing evidence suggests that people with cancer and other conditions that challenge their immune systems may be incubators of mutant viruses.
The variant contains a mutation thought to help the virus dodge the immune system, scientists said.
The find supports the idea that dogs accompanied the first humans who set foot on these continents—and that both traveled there along the Pacific coast.
The virus is mutating as expected. We can still stop it.
A South African tip led to the discovery of mutations around the world. With infections skyrocketing, “it’s a race against time.”
Two studies move us closer to understanding the origins of life on our planet. They may also help with another of the great mysteries of science - helping us to understand where to look for life on other planets.
It’s not just what makes males into males. The sex chromosome also influences health in hidden ways, some experts believe, and may even explain why men have shorter life spans.
Viruses have been a part of our lives for so long, in fact, that we are actually part virus: the human genome contains more DNA from viruses than our own genes.
We laugh even before we can speak, but why? Science has some answers to the mystery of human laughter, and some of them might surprise you
