The people who submit the top 5 entries will receive a travel subsidy of $800 (or $1200 for international subm... Read More
Dear Twim team
An interesting paper on artificial selection of yeast giving rise to evolved clusters. The clusters evolved to be larger, produce multicellular progeny, and even s... Read More
As the world’s athletes limber up for the forthcoming Olympic games in London, infectious-disease experts are preparing for their own trials. Their competition is with the diseases that millions of athletes, officials, media and spectators bring with them as they converge from across the globe o... Read More
Elio Schaechter of Small Things Considered has authored an interesting post today about the motility of bacteria, specifically Paenibacillus, although he does highlight several other strains that swarm, glide or twitch.
"Microbes get around. They can be carried by the wind, by insects, or by ... Read More
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
One of the most economically devastating diseases in the world for those who raise cows, sheep, pigs, goats, deer and other cloven-hoofed animals is foot and mouth Disease (FMD). This incredibly contagious and fast-spreading disease causes fever, blisters on the feet and mouth (hence the name), ... Read More
It was a provocative finding: strange bacteria in a California lake that thrived on something completely unexpected — arsenic. What it suggested is that life, a very different kind of life, could possibly exist on some other planet.
The research, published by a leading scientific journal in 2... Read More
A species of small, transparent roundworms have a highly evolved language in which they combine chemical fragments to create precise molecular messages that control social behavior, reports a new study from the Boyce Thompson Institute (BTI) at Cornell and the California Institute of Technology ...

Understanding what happens to a soybean root hair system infected by symbiotic, nitrogen-fixing soil bacteria, Bradyrhizobium japonicum, could go a long way toward using this symbiosis to redesign plants and improve crop yields, benefitting both food and biofuel production. Because of their exte... Read More

Ron Fouchier has discussed his influenza H5N1 transmission experiments in ferrets at an ASM Biodefense Conference, clarifying several assumptions about the transmissibility of the virus in this animal model. Read More
Nearly four months ago I stood at the front of a crowded classroom at Columbia University and began teaching the third year of my undergraduate virology course. Twice a week we discussed the basic principles of virology, including how virions are built, how they replicate, and how they cause dis... Read More
Mak Saito, a biogeochemist at Woods Hole Oceanographic Institution, has been selected for a Marine Microbiology Initiative (MMI) investigator award by the Gordon and Betty Moore Foundation. Saito is one of 16 scientists from 14 different institutions who will receive funds from a total of up to ... Read More
The fatality rate for human infections with avian influenza H5N1 is widely quoted at >50%, based on the number of deaths among the fewer than 600 cases confirmed by the World Health Organization. Wang, Parides, and Palese suggest that this number is an overestimate. Read More
Hello Men (and sometimes women) of TWiV!
I have read before that the human genome contains the genetic code of several thousand retroviruses. These retroviruses are in an inactive state, and are believed to be the product of infec... Read More
This is a brief scientific simulation displaying our current understanding of how bacteria acquire resistance. It's from the FDA's Center for Veterinary Medicine website. Thanks to Youtube user DrKPW for posting this! Read More
