Retroviruses are viruses that multiply by incorporating their genes into the genome of a host cell. If the infected cell is a germ cell, the retrovirus can then be passed on to the next generation as ...

Researchers report that ancient viruses may be to thank for myelin -- and, by extension, our large, complex brains. The team found that a retrovirus-derived genetic element or 'retrotransposon' is ...

Human DNA isn't actually entirely human. Strangely, a lot of our genetic material came from unwanted guests hitching rides in ...

Human DNA is not always making us function in ways we understand. Some of our genome is just there, and we’re not sure what it does. In fact, 8% of our DNA are viruses our ancestors caught one day and ...

Retroviruses - the family of viruses that includes HIV - are almost half a billion years old, according to new research by scientists at Oxford University. That's several hundred million years older ...

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 ...

Madagascar is home to a unique biodiversity with a large number of endemic species, among those many lemur species, including the mouse lemurs. This diversity is also found in their retroviruses, a ...
