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
This episode: Engineered bacteria could help capture CO2 and convert it into a solid form for storage!

E. coli engineered to produce the enzyme carbonic anhydrase, which converts carbon dioxide to bicarbonate and then to calcium carbonate,... Read More
Influenza A viruses typically cause severe respiratory disease mainly in the very young or the elderly. The 2009 swine-origin H1N1 virus is unusual because it preferentially infects individuals under 35 years of age. We’ve previously noted that being older is a good defense against 2009 H1N1 inf...

An interesting presentation given by Yuri Gorby, an electromicrobiologist at the J. Craig Venter Institute in San Diego, at CalIT2 at UCSD on electronmicrobiology. Here's part of the description from SciVee.tv:
Respiratory microorganisms capture energy for growth and maintenance as they trans... Read More
This episode: Cold-loving bacteria can repair surprising amounts of DNA damage even sub-zero temperatures!

Bacteria isolated from the Siberian arctic permafrost are exposed to a lot of radiation over thousands of years, but somehow they are able to repair... Read More
Many protozoan parasites (Trichomonas, Leishmania, Giardia, Plasmodium, Entamoeba, Nagleria, Eimeria, Cryptosporidium) are infected with viruses. These viruses do not infect vertebrates, but their double-stranded RNA genomes are sensed by the innate immune system, leading to inflammatory complic... Read More
I am always looking for microbe-themed art; I keep a list of my findings at Microbe Art. I’ve just discovered a new artist: Jane Hartman of Trilobite Glassworks. From her website: Trilobite Glassworks features stained glass and fused glass decorative as well as functional pieces all designed and... Read More

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
When I am asked to name the most lethal human virus, I never hesitate to name rabies virus. Infection with this virus is almost invariably fatal; just three unvaccinated individuals have been known to survive. New evidence from humans in the Peruvian Amazon suggests that the virus might be less ... Read More
This is a blog that tries to address the relationships between genes and environmental risk factors , particularly viruses, bacteria and parasites, in some common diseases, including Alzheimer's disease, Bipolar disorder, multiple sclerosis, Schizophrenia and Parkinson's disease and also provide...

Fluorescence-tagged Escherichia coli cells can be made to "blink" in unison by means of a constructed network of genes and proteins that coordinates oscillations within the growing cell population, according to Jeff Hasty and colleagues from the University of California, San Diego (UCSD) in La J...
