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 ...

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, ...

The death toll and economic damage associated with flu highlight its role as one of the most harmful viruses in history.

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 ...

Four years ago the first modern electron microscope was exhibited by the Siemens & Halske A.-G., in Berlin (TIME, June 6, 1938). Two years ago the R.C.A. Laboratories completed the first commercial ...

Researchers have shown that expensive aberration-corrected microscopes are no longer required to achieve record-breaking microscopic resolution. Researchers at the University of Illinois at ...

A group of McMaster researchers who routinely work with bacteriophages—viruses that eat bacteria—had a pleasant and potentially very important surprise while preparing slides to view under a powerful ...

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 ...
