Most influenza viruses enter human or animal cells through specific pathways on the cells' surface. Researchers have now discovered that certain human flu viruses and avian flu viruses can also use a ...

Infection with Zika virus in pregnancy can lead to neurological disorders, fetal abnormalities and fetal death. Until now, how the virus manages to cross the placenta, which nurtures the developing ...

For much of modern biology, scientists argued that viruses are not alive, pointing to a basic limitation: they cannot make proteins on their own and must depend entirely on the cells they infect for ...

As part of their effort to answer a decades-old biological question about how the hepatitis B virus (HBV) can establish an infection in liver cells, researchers led by teams at Memorial Sloan ...

Viruses are typically described as tiny, perfectly geometric shells that pack genetic material with mathematical precision, but new research led by scientists at Penn State reveals a deliberate ...

For the first time, researchers have observed live and in high resolution how influenza (“flu”) viruses infect living cells. This was possible thanks to a new microscopy technique, developed at ETH ...

H5N1 avian influenza is highly pathogenic and has been devastating bird populations worldwide. It continues to do so, and is also moving into new animals, like skunks, bears, raccoons, cats, and dairy ...

A live-cell imaging tool allowed researchers to follow influenza A virus through its life cycle in airway organoids, showing ...

A new study has overcome a long-standing challenge: how to isolate and study elusive HIV-infected cells called authentic reservoir clones (ARCs) that evade the immune system, making the disease ...

Epstein–Barr virus infects most adults. Understanding its role in Multiple Sclerosis could transform prevention and treatment ...
