The Rise of Genomic Superspreaders

Are you, Alan Dove and Prof. Racaniello, saying you think Mikovits and/or others on the Lombardi paper lied about the results or blinding? I think circumspection is a natural human reaction to the allegations of theft that have been made against Dr. Mik... Read More

What Happened to Our Friendly Enterococci?

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

Norton Zinder, 1928-2012

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. Later in his own ... Read More

Dear TWiV,


The epidemiology episode with Michael Walsh was great. I loved the philosophical detour into counterfactual statements, time travel, and the meaning of causation. TWiV may indeed be viral, but from listening to it I fee... Read More

Influenza H5N1 virus versus ferrets, round two

The second of two papers on avian influenza H5N1 virus that caused such a furor in the past year was published today in the journal Science. I have carefully read the paper by Fouchier and colleagues, and I assure you that it does not enable the production of a deadly biological weapon. The resu... Read More

Can India remain polio-free?

India has been free of polio for over one year. This is a remarkable accomplishment, considering that just 30 years ago the country recorded 200,000 cases of the disease annually, or one every three minutes.

The Three Faces of Thiomargarita

Merry Youle of Small Things Considered has authored a post that looks at Thiomargarita spp.

"Non-motile Thiomargarita was first discovered in 1999 off the Namibian coast, thus was named T. namibiensis. Its cells are large spheres, arranged in chains, each chain enclosed in a mucous sheath. Av... Read More

Oddly Microbial: 86 Million Year-Old Deep Seabed Mystery Cells

Life in a high-pressured environment with practically nothing to eat might be ok for high-fashion models, but it’s an unlikely lifestyle choice for a single cell whose usual overriding goal is to become two cells. Yet the largest living ecosystem on Earth—the deep biosphere—is comprised of micro... Read More
