In the shadows of Python Cave, Uganda, a leopard leaps from a guano mound—formed by bat excrement—and sinks its teeth into a ...

New imaging tools reveal how within an hour of infection, the virus begins to alter our chromosomes to kick-start its own replication.

Because they rely on hosts for a majority of functions, viruses aren’t considered alive. But entities like ‘Sukunaarchaeum ...

If we don’t invest in technologies like mRNA vaccines for pandemic influenza now, once a virus starts going human-to-human, ...

Antiretroviral therapy (ART) initiated in the acute phase of HIV infection (AHI) results in a smaller viral reservoir. However, the impact of early HIV-specific T-cell responses on long-term reservoir ...

Human immunodeficiency virus (HIV) is a germ that causes a lifelong infection that slowly weakens the immune system. Though the infection is lifelong, medicines can keep the virus in check and help ...

"We've known that circular RNAs show up in DNA viruses like Epstein-Barr and the human papillomavirus, but seeing that they are generated by an RNA virus like HIV-1 is incredibly exciting," said ...

So, here you have RNA viruses that function as clouds. Then we realized that Polio is an RNA virus, and so is yellow fever and COVID-19. ... Our challenge was to determine if we could trick the body ...

For nearly seven decades since their discovery in 1898, viruses were the only organisms at the boundary between the living and the non-living. Their obligate host dependence, parasitism, and small ...

Viruses are always changing, and that can cause a new variant, ... Researchers were studying changes in coronavirus RNA over time to figure out how various coronaviruses are related to each other.

(Left) As in Figure 5, RNA has a hydroxyl group that is 5 atoms (just the right bonding distance) from the phosphate group (blue arrow) that holds RNA (and DNA) together. This promotes a cyclization ...
