How do one-celled parasites move from the salivary gland of a mosquito through a person's skin into red blood cells? What molecular mechanisms form the basis for this very important movement of the protozoa? A team of researchers headed by Dr. Friedrich Frischknecht, head of a research group at ... Read More
It is well known that virus populations display phenomenal diversity. Virus populations are dynamic distributions of nonidentical but related members called a quasispecies. This diversity is restricted in single cells, but is restored within two infectious cycles. Read More
The TWiVocytes answer questions about Ebola virus, including mode of transmission, quarantine, incubation period, immunity, and much more.
The lethality of avian influenza H5N1 infections in humans has been a matter of extensive debate. The >50% case fatality rate established by WHO is high, but the lethality of the virus might be lower if there are many infections accompanied by mild or no disease. One way to answer this question ... Read More
Hey Vincent, Elio, Michele and Michael!
I'm a first year microbiology graduate student at UC Berkeley and an avid listener of twim. Elio's snippet from the most recent podcast reminded me of a personal anecdote that might be useful to share with... Read More
Vinny and the capsids answer listener questions about the definition of life, state vaccination laws, the basic science funding problem, viral ecology, inactivation of viruses by pressure, and much more.

This episode: Artificial proteins actually function in bacteria!
I have been following TWIP for several years. I am a software engineer and parasitology is only an avocation. As an undergraduate in the early 80's I discovered my love of history of science and ecology, although I continued the p... Read More
I did a study of hand washing and hand sanitizer. Is anyone on the list willing to help me identify what grew from my unwashed and even washed hands? I attach three photos representing the yellow, white and orange growths found after several days on agar plates. Thank you so much in advance. Read More
This recent talk at TED by Bonnie Bassler on bacterial communication (aka quorum sensing) was a viral hit among the science geeks on Twitter. It is a very educational and well thought out presentation that is great for personal viewing or showing in the classroom. It's a must watch! Read More
Safe, cheap and effective adjunct therapies preventing the development of, or reducing the mortality from, severe malaria could have considerable and rapid public health impact. Oral activated charcoal (oAC) is a safe and well tolerated treatment for acute poisoning, more recently shown to have ... Read More
I'm a computer programmer who listens to podcasts on my long commute. The highest science education that I've had was college Chemistry. As an Electrical Engineer the science classes we took tended to not be biology oriented, so while so... Read More
Blogs, podcasts, and other new media outlets have changed the way people get their news. Immediate access to information presents new opportunities as well as challenges for science communication. Watch Carl Zimmer, science wr... Read More

I just listened to the latest TWiM. Thanks for covering our horizontal gene transfer paper! It was great to hear you all talk about it and give your thoughts.
With regards to the selective pressure for retention of the Dae’s in genomes o... Read More
How XMRV, the new human retrovirus associated with prostate cancer and chronic fatigue syndrome, might be transmitted among humans is unknown. The finding that the virus can be detected in prostate cancer cells, and in prostatic secretions of men with prostate cancer suggests that it could be se... Read More
I came across this paper and thought it sounded interesting for a discussion on TWiP:
