One of the basic requirements of evolution is variation in a population upon which selection can act. One of the sources of variation is mutation in DNA. These changes may or may not be reflected in the ensuing amino acid sequence of a protein. This exercise explores the additive effects of m... Read More
When you purchase chicken eggs at the market, they usually have white or brown shells. But some breeds of chicken produce blue or green eggs. The blue color is caused by insertion of a retrovirus into the chicken genome, which activates a gene involved in the production of blue eggs. Read More
After having listened to your discussions on Plasmodium (TWiP 64), I explored papers on treatment options that are actually available. After having read some papers, I realized that one of the main roadblocks are the hypnozoite... Read More
Hi guys really like the show even though some of it (not much) goes over my head. I also listen to twip and hope there will be a matching number of episodes to rival twiv. My name is Michael and I was talking to my dad the other day and he mentioned that he t... Read More
My wife Jennifer Quinn hits it out the park: a portrait of Kenneth Nealson and the late Woody Hastings "painted" with luminous bacteria, giving them props for the early days of quorum sensing---where the basic principles were first uncovered in bioluminescent microbes. This principle of "aut... Read More
Chimpanzees from African sanctuaries carry drug-resistant, human-associated strains of the bacteria Staphlyococcus aureus, a pathogen that the infected chimpanzees could spread to endangered wild ape populations if they were reintroduced to their natural habitat, a new study shows.
The study ... Read More

Here is a follow-up to last week’s article that described a case of variant Creutzfeldt-Jacob disease in a Texas resident caused by ingestion of BSE-contaminated beef 14 years ago.
A 59 year old male patient was admitted to the trauma unit in Lancaster, PA with a self-inflicted gunshot wound ... Read More
Dear TWIM Team,
First of all, thanks for the supremely informative and entertaining podcast. As a biologist who stumbled into my passion for microbiology almost by accident (as a student, I began my research as a herpetologist and was converted wh... Read More
I am attempting to compile a list of reporters who do a good job covering microbiology related topics. I have compiled a partial list and am soliciting additional suggestions. Read More

As my Fall semester approaches, I am reflecting on last Fall. I taught a freshman seminar course revolving around symbioses and parasitism, and was fortunate to have many well known scientists be willing to "virtually visit" my class! Here is my report from last year on the great Jack Gilbert.... Read More
Both Nature and the New York Times have weighed in on the resumption of influenza H5N1 research. In an editorial from 23 January 2013, Nature opines that “Experiments that make deadly pathogens more dangerous demand the utmost scrutiny”. They call for a quantitative risk-benefit analysis of H5N1... Read More
