This episode: Bacteria help ants keep parasites out of their fungal gardens!
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....

This episode: Some insects have bacterial symbionts with super-small genomes inside their cells, and some of these symbionts have their own internal bacterial symbionts!
This episode: Bacteria as fertilizer!
Hi Vincent and Dickson,
I enjoy TWIP, and often recommend it to my students. I'm a parasitologist, primarily a Leishmaniac, but I have learnt a lot from TWIP. I find it both more educational and entertaining than Car Talk.
The disc... Read More

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
Dear Vincent and Dickson,
I just heard your most recent TWIP. Please keep these podcasts going! I love listening to your podcasts and hearing your enthusiasm for my favorite biological topic, parasites. Remember that for every fan... Read More
When I began listening to TWIV almost a year ago, I had just switched majors from philosophy to biology. I am now writing to you good people at TWIM at the end of my first undergraduate summer research gig, where I have had qui... Read More
We typically spend close to 90 percent of our time inside - at school, work and home. While outdoor air quality is very important, so too is the quality of the air we breathe at home and the office. Yet most of us know very little about the condition of our indoor climate. The chemicals ... Read More
Current HIV treatments do not eradicate HIV from host cells but rather inhibit virus replication and delay the onset of AIDS. However, a new research published in BioMed Central's open access journal, AIDS Research & Therapy describes an innovative approach to eliminate HIV in host by targeted ... Read More
Thirty years ago this month I arrived in the Department of Microbiology at Columbia University’s College of Physicians and Surgeons (P&S) to start my own laboratory. Thirty is not only a multiple of ten (which we tend to celebrate), but also a long time to be at one place. It’s clearly time to r... Read More
A serological test is highly accurate at finding tuberculosis infection in elephants, and can determine such infection years before culture, according to a study in the August Clinical and Vaccine Immunology (click source to download the .pdf of the journal article). The issue is critical not on... Read 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
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
In 2011, for the first time, countries across the WHO regions of Africa, Americas, Eastern Mediterranean, Europe and the Western Pacific are taking part in simultaneous immunization weeks. This unprecedented collaborated effort between the regions is building public and professional awareness of... Read More
