The massive cuts to science, global health, and HIV programs that unfolded in 2025 triggered a crisis with worldwide repercussions. The dissolution of USAID, the shutdown of PEPFAR, and the suspension ...

The effects of aging pose an additional challenge for people with HIV due to the neurological and psychological consequences ...

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 ...

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 ...

Working with the example of koalas, the researchers have now identified key stages in the process, called "endogenization", by which a host is invaded by exogenous retroviruses. The scientists also ...

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 ...

Viruses are ubiquitous entities that have long plagued humans, often presenting in pesky, self-limiting infections, like a bout of the common cold. While most viral encounters are transient and merely ...

Previous studies have shown that fragments of ancient viral DNA — called endogenous retroviruses — in the genomes of mice, chickens, cats and sheep provide immunity against modern viruses that ...

Antisense technology has made little headway as a therapeutic approach to retroviral infection. But this may change if results reported in this issue by Moelling and colleagues 1 prove robust and ...

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.

Historic virus infections can be traced in vertebrate genomes. For millions of years, these genomes have been repositories for retroviruses that incorporated their code into germline cells and were ...
