Viruses have no metabolism of their own and must therefore infect host cells in order to replicate. Contact between the virus and the cell surface is a crucial first step, which can also prevent ...

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 ...

We’ll understand if you’re puzzled by the eerie image below. It’s a tiny piece of the Lassa virus, which can double a person over in pain, make their head swell and, in some cases, quickly result in ...

The penetration of viruses into cells can now be tracked with unprecedented accuracy thanks to an innovative design for pseudoviruses. Pseudoviruses resemble impostors: although harmless, they are ...

A new kind of microscope is giving scientists a way to watch life inside cells with a clarity that feels almost unfair. Instead of choosing between seeing big structures or tiny particles, researchers ...

Using a tiny, spherical glass lens sandwiched between two brass plates, the 17th-century Dutch microscopist Antonie van Leeuwenhoek was the first to officially describe red blood cells and sperm cells ...

Herpes simplex virus partially liquefies the tightly packed, gel-like interior of human cell nuclei to copy itself faster, a new study shows. The research centers on how the nucleus of each human cell ...

The COVID-19 pandemic led to heightened public interest in learning about viruses and how they can cause diseases. There has been a lot of focus on communicating virology concepts to the general ...

Scientists have discovered that viruses can latch onto other viruses to insert their genes into host cells. Lab results with apparent contamination led the team to directly see the strange interaction ...
