As a developmental biologist and post-doc, I greatly enjoy your show which gives me both information and distraction from pipetting small volumes from one tube to another in the lab. Recently, my lab enjoyment was cut short by a w... Read More
Dear TWiM Team
A fascinating article from New Scientist this week.
Standard medical teaching is that the foetus is sterile and that the microbiome only begins to develop post natal.
New research from Spain indicates that the microbiome s... Read More
Science writer Carl Zimmer writes a masterful blog piece tracing the history of the study of ecosystems, from lakes to the human microbiome. Just one interesting fact: In their lifetimes, individual humans will produce about five elephants worth of microbes. Read More
Vince, here is the text of my post on Peter S site. I was disappointed in the quality of his article as I have much previous experience with his work and see him as the "David Baltimore of Risk Communication". If you could get him on as a guest you would e... Read More
TWiV 82 letters
Yesterday I sent my Skype audio question again, and I think it worked this time. In my question I mentioned a particular youtube video. Here's the link if you want to see what I was referring to. It's only 5 minute... Read More
Jeff Fox of Microbe magazine interviews Kim Lewis of Northeastern University--
Missing siderophores may account for why microbiologists can culture only about 1% of the microorganisms that they collect from diverse environments, according to Kim Lewis of Northeastern University and his collabor... Read More
A second virophage has been identified. The name does not signify a virus that infects another virus – it means virus eater.
Vince and Dickson,
You both have probably seen this already, but for TWIP and TWIM listeners fighting malaria with transgenic fungi is the first item in the 41 minute podcast for 25 Feb 2011, from http://www.sciencemag.org/ . This sounds both fascinating ... Read More
Some viruses that infect bacteria (bacteriophages) deliver their DNA into the host cell with an amazing injection machine. The tailed bacteriophages (such as T4, illustrated) store their DNA in a capsid attached to a long tail tube that is surrounded by a sheath. At the bottom of the tube is a b... Read More
An article by Alan Derman, Project Scientist in Joe Pogliano’s lab at the University of California at San Diego, published on the Small Things Considered blog presents a point-by-point analysis of a paper "Quantitative genome-scale analysis of protein localization in an asymmetric bacterium" pub...

Dear Twiv Folks
I teach an intro biology course on viruses at Vassar College. We do our introductory biology a little bit differently; each class has a theme through which we explore the fundamental principles of biology. Mine is on viruses and t... Read More
When my laboratory discovered the cell receptor for poliovirus in 1989, many new research directions were suddenly revealed – such as creating a mouse model for poliomyelitis. One application we did not think of was to use the receptor to screen samples of drinking water for the presence of viru... Read More
Yesterday the Chicago Tribune published my reaction to the four papers on the retrovirus XMRV published this week in the journal Retrovirology. I was quoted as saying ”These four papers are probably the beginning of the end of XMRV and CFS”. I wish to retract this statement and explain my reason... Read More
At first glance, the inaugural 1812 issue of the New England Journal of Medicine and Surgery, and the Collateral Branches of Science seems reassuringly familiar: a review of angina pectoris, articles on infant diarrhea and burns. The apparent similarity to today's Journal, however, obscures a fu... Read More
