Major histocompatibility (MHC) molecules enable T lymphocytes to recognize epitopes of antigens and discriminate self from nonself. Unlike B-cell receptors on B lymphocytes that are able to directly bind epitopes on antigens, the T-cell receptors (TCRs) of T lymphocytes can only recognize epitop... Read More
For my Microbiology course at the University of Puget Sound, I decided to ask my new crop of "micronauts" what the word "microbiology" meant to them on the first day of class. Here are their answers. My wife Jennifer Quinn and I put this together using art from former students. Hopefully, thi... Read More
Los virus son considerados por la mayoría como patógenos en todo tipo de entidades biológicas. Sin embargo la gran mayoría de los virus son inocuos a sus células hospedero. Nuestro invitado de hoy, el Dr. Paolo Zanotto es investigador y profesor en la Universidad de Sao Paolo, Bra... Read More
Dear Vincent and Dickson,
Listening to TWiP on cyclosporiasis. Because I am all too aware of the possible contamination of many crops as a former public health nurse who worked in epidemiology for my state (Florida), I always wash my fruits and v... Read More
Few technical breakthroughs have changed the face of their field like the Polymerase Chain Reaction (PCR). Gene cloning, sequencing of complex genomes, DNA fingerprinting and DNA-based diagnostics are just some of the techniques that were either inefficient, crude or plain impossible before PCR....

Michael returns to help the TWiP trio solve the case of the Delusional African Expatriate, who then discuss the association of natural and induced antibodies in mice with differential susceptibility to secondary cystic echinococcosis.

Tomorrow is the start of my new virology course at Columbia University. The course, Biology W3310, is aimed at advanced undergraduates and will be taught at the Morningside Campus of Columbia University. Read More
This was indeed not easy to Google; one of my attempts even had a dr oz page as one of search results. Clearly a dead end. However with some persistence I came up with Entamoeba Histolytica.
The TWiV gang reviews ten fascinating, compelling, and riveting virology stories from 2014.

David writes (re lice and iron):
All I remember that I know is that one time I let my cat endure a heavy flea infestation for an unconscionably long time. I redeemed myself, if at all, by the knowledge that I slept with her a lot, and so endured a share myself (b... Read More
Patients undergoing FMT have often suffered for years prior to the therapy. If their homes have been contaminated with the eradicated microbe, could patients suffer a relapse by way of reinoculation? This was the question asked by a group of physician scientists, whose findings were recently pub... Read More

Claire Fraser-Liggett, Director of the Institute for Genome Sciences and professor at the University of Maryland School of Medicine, gives the June 2, 2010 keynote at the "Sequencing, Finishing, Analysis in the Future" meeting in Santa Fe, NM. Read More
A deep sequencing study of commercially available probiotics, and design and synthesis of a minimal bacterial genome are the topics tackled by Vincent, Michael, and Michele on this episode of TWiM.
As noted entomologist E.O. Wilson accepts his 2007 TED Prize, he makes a plea on behalf of his constituents, the insects and small creatures, to learn more about our biosphere. Wilson states that as we're still discovering tiny organisms indispensable to life we're steadily, methodically, and vi... Read More
This lecture covers the biochemical basis of actin-based motility (focusing on the pathogen Listeria as a model system for this process), the biophysical mechanism of polymerization-based force generation, and an evolutionary perspective of cell shape in prokaryotes and eukaryotes. The first par... Read More
