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 ...

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 ...

In a quiet freshwater pond in Ibaraki Prefecture near Tokyo, researchers have pulled from the water a microscopic giant that is forcing biologists to rethink how complex life began. The newly ...

A new, nano-scale look at how the SARS-CoV-2 virus replicates in cells may offer greater precision in drug development, a Stanford University team reports in Nature Communications. Using advanced ...

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 ...

For a long time, researchers contested the presence of microscopic pathogens suspected of causing various diseases in plants and animals. The invention of the electron microscope in 1933 made them ...

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. A research ship sails in the Atlantic Ocean, where scientists are studying the roles of marine viruses. SW Wilhelm Virus. The word ...

Watch a white blood cell actively searching for bacteria or viruses under the microscope.
