Distinguishing between self and non-self is a critical ability of the immune system. Some pathogens have evolved proteins that resemble those of their host, a mechanism called molecular mimicry, in an ...

Researchers recovered a 250-year-old cold virus from preserved lung tissue, offering rare insight into how respiratory viruses evolved.

Around 8 percent of human DNA is made up of genetic sequences acquired from ancient viruses. These sequences, known as human endogenous retroviruses (or Hervs), date back hundreds of thousands to ...

In a groundbreaking study, scientists have discovered more than 100 new human viruses in 252 different gut microbes, providing a remarkable look at our bacteria and forming the very first living model ...

You, my friend, are what scientists call a "holobiont"- an organism made up of human cells and the multiplicity of microscopic species living inside you and on your body. Many of these microorganisms ...

Scientists have long known that a significant portion of the human genome is made up of the remnants of ancient viruses; these sequences are a subset of transposable elements known as endogenous ...

In 1990, I finished my PhD on primate evolution and went to my postdoc in Davis, California, USA. It was meant to be on fruit fly ...

The authors do not work for, consult, own shares in or receive funding from any company or organization that would benefit from this article, and have disclosed no relevant affiliations beyond their ...

For over a decade, scientists have studied the microbiome, the environment of microorganisms that live on and in the body, and how it affects health and disease. Much less is known about a part of the ...

Bird flu viruses are a particular threat to humans because they can replicate at temperatures higher than a typical fever, one of the body's ways of stopping viruses in their tracks, according to new ...
