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 ...

A new kind of microscope is giving scientists a way to watch life inside cells with a clarity that feels almost unfair.

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 ...

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 ...

Bird flu viruses may pack a little taste of home to help them adapt to life in new hosts. Despite plenty of instances of bird flu viruses infecting people, scientists weren’t sure exactly how the ...

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 ...

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 ...

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 ...
