A virus that is big enough to be seen under an ordinary light microscope co-opts its host’s systems with the help of ...

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 ...

For much of modern biology, scientists argued that viruses are not alive, pointing to a basic limitation: they cannot make proteins on their own and must depend entirely on the cells they infect for ...

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 ...

Current calibration methods rely on artificially constructed DNA structures or specific cellular features, each with significant drawbacks. DNA-based rulers require complex chemical synthesis and only ...

ST. LOUIS -- Even as scientists were confirming that the West Nile virus had reached St. Louis, researchers here already have been trying to pinpoint why the mosquito-transmitted form of encephalitis ...

A live-cell imaging tool allowed researchers to follow influenza A virus through its life cycle in airway organoids, showing most infections stall during viral RNA transcription, highlighting targets ...

Human DNA is not always making us function in ways we understand. Some of our genome is just there, and we’re not sure what it does. In fact, 8% of our DNA are viruses our ancestors caught one day and ...
