Drugs made of mRNA have the potential to transform medicine—if only they could get into cells in one piece. Now, University ...

New findings published in the journal Cell about the Andes virus, a hantavirus endemic to the southwestern U.S. and other ...

A giant virus discovered in Japan is adding fuel to the provocative idea that viruses helped create complex life. Named ushikuvirus, it infects amoebae and shows unique traits that connect different ...

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 ...

Scientists have finally watched influenza viruses break into living human cells in real time, catching the microscopic invaders as they latch on, glide across the surface and slip inside. Instead of a ...

A type of immune cell targeting the Epstein-Barr virus may play a key role in driving multiple sclerosis (MS), a study found.

New study reveals how influenza virus infiltrates heart tissue via specialised immune cells, triggering damaging interferon ...

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 ...

Researchers at the University of California, Davis, have traced a deadly cat coronavirus in a way that changes what you think ...

The influenza virus manipulates the body's gene regulation system to accelerate its own spread. A new study also shows that an already approved drug could help strengthen immune defenses -- though its ...
