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 ...

Researchers have captured the first real-time footage of viruses on the move, right before they hijack a cell. When Courtney "CJ" Johnson pulls up footage from her Ph.D. dissertation, it's like she's ...

Despite their name, giant viruses are difficult to visualize in detail. They are too big for conventional electron microscopy, yet too small for optical microscopy used to study larger specimen. Now, ...

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 ...

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 ...

In March 2020, Tagide deCarvalho saw something truly strange — something she thinks no other scientist has ever seen before: a virus with another, smaller virus latched onto its “neck.” The backstory ...

The phenomenal new electron microscope (TIME, Dec. 14, 1942) has been taking a good long look at hitherto invisible objects. In the last two issues of the Journal of the American Medical Association, ...
