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 ...

Modern laboratory techniques for the detection of novel human viruses are greatly needed as physicians and epidemiologists increasingly deal with infectious diseases caused by new or previously ...

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, ...

Scientists have captured an unprecedented, real-time view of influenza viruses as they move across and slip inside human cells. The footage reveals that cells are far from passive targets and instead ...

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

A comparison of experimental annular dark field (ADF)-scanning transmission electron microscopy (STEM) and electron ptychography in uncorrected and aberration-corrected electron microscopes. In the ...

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 ...

Scientists have discovered that viruses can latch onto other viruses to insert their genes into host cells. Lab results with apparent contamination led the team to directly see the strange interaction ...

Timothy S. Baker was born in Hackensack, New Jersey. He obtained a B.S. in chemistry from Duke University and a Ph.D. in biochemistry from the University of California, Los Angeles. Baker did ...

Cheese fungus, head lice, human sperm, a bee eye, a microplastic bobble: scientific photographer Steve Gschmeissner has imaged them all under the probing lens of a scanning electron microscope (SEM).
