Researchers have identified a previously unknown giant virus that may offer new insight into how complex life first evolved.

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 ...

A new study shows that the body’s early immune response, not the virus itself, often determines how severe a rhinovirus cold ...

How flu viruses enter cells has been directly observed thanks to a new microscopy technique with the potential to revolutionize research on membrane biology, virus–host interactions and drug discovery ...

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 ...
