Apple's iPhone 5S and 5C might be all the rage at the moment. (Did you get a gold one??) But one college professor thinks smartphones should have a higher purpose. By "higher," I mean detecting things ...

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 ...

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 ...

Scientists are reporting an advance in smartphone-based imaging that could help physicians in far-flung and resource-limited locations monitor how well treatments for infections are working by ...

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 Sketch of the PRISM system, where an all-dielectric photonic crystal (PC) is used as the sample substrate and illuminated by a collimated 633u2009nm HeNe laser beam. Inset: normal-incident ...

Lurking in the vast expanse of the ocean and buried deep in the Siberian permafrost, there are giants—not blue whales and ...

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, ...

DURHAM, N.C. -- When Courtney “CJ” Johnson pulls up footage from her Ph.D. dissertation, it’s like she’s watching an attempted break-in on a home security camera. The intruder cases its target without ...
