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 ...

Bacteriophages, or phages, viruses that selectively target and infect bacteria, have drawn growing attention for their potential use in a host of biotechnological processes to benefit humankind, from ...

Add Yahoo as a preferred source to see more of our stories on Google. Composite of three mages from new microscope technology show a cell's replication machinery in green, already-replicated DNA is ...

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 ...

A virus that is big enough to be seen under an ordinary light microscope co-opts its host’s systems with the help of potentially purloined genes. The researchers found that the virus makes a complex ...

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 ...

Herpes simplex virus partially liquifies the tightly packed, gel-like interior of human cell nuclei to copy itself faster, a ...

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 ...
