Norton Zinder made two important discoveries in the field of virology. While a Ph.D. student with Joshua Lederberg at the University of Wisconsin-Madison he found that viruses of bacteria (bacteriophages) could move genes from one host to another, a process called transduction.

Enterococci had been generally regarded as benign commensals, a part of our healthy intestinal microbiota. They were even invited in, being used as probiotics. But then, in the late 1970s, the first multiple drug-resistant strains appeared, and vancomycin-resistant strains followed in 1981. In r... Read More

There is an excellent question in the comments to “Are all virus particles infectious?“: if the particle-to-PFU ratio for a virus stock is 10,000:1, and I infect 1,000,000 cells with 10,000 particles, how many plaques would I expect to observe? Answering this question provides insight into the p... Read More

The figure for the number of prokaryotic cells on the planet, roughly 5x1030, is considerably greater than that of the estimated number of stars in the firmaments (3x1023). These two numbers have one thing in common: they both grew hugely and rather suddenly in recent human history.
