Retroviruses -- the family of viruses that includes HIV -- are almost half a billion years old, according to new research. That's several hundred million years older than previously thought and ...

A cluster of antiviral genes in humans has likely battled retroviral invasions for millions of years. New research now finds that in addition to the previously identified TRIM5 gene that can defend ...

Bats have long been known as important hosts of zoonotic viral pathogens. Zoonotic viruses that bats transmit are capable of infecting humans and have caused devastating infections throughout the ...

Scientists from the University of Colorado, Boulder (CU Boulder), have published new research in Science Advances that shows that endogenous retroviruses (ERVs)—“junk DNA”—in the genome can play a ...

Retroviruses probably evolved roughly half a billion years ago, making this medically and economically important group of viruses five times older than scientists previously thought. The finding, ...

New findings offer insight into why some embryos fail to develop past zygotic genome activation (ZGA), pointing to an unexpected root of human infertility. A critical point in early development is ...

Researchers report February 15 in the journal Cell that ancient viruses may be to thank for myelin—and, by extension, our large, complex brains. The team found that a retrovirus-derived genetic ...

Scientists in the lab of Professor of Biology Welkin Johnson, shown above with then-undergraduate researcher Nirali Patel '15, study viruses ranging from HIV/AIDs to those that affected modern mammals ...

An international team of scientists has analyzed the ongoing colonization by two retroviruses of the germline of koalas and resulting deaths from cancer in multi-generational pedigrees of over 100 ...

Retroviruses probably evolved roughly half a billion years ago, making this medically and economically important group of viruses five times older than scientists previously thought. “These viruses ...
