The World Health Organization has decided not to recommend destruction of the remaining stocks of smallpox virus. This debate has been ongoing since 1980, when the disease was declared eradicated. WHO has indicated that no new experiments on smallpox virus will be permitted, only conclusion of o... Read More
How about using compost that includes road kill? I heard a billion pounds of animal byproducts go to landfills rather than into animal feed to prevent spread of mad cow disease. Compost that, too?
Influenza A virus reservoirs in animals have provided novel genetic elements leading to the emergence of global pandemics in humans. Most influenza A viruses circulate in waterfowl, but those that infect mammalian hosts are thought to pose the greatest risk for zoonotic spread to humans and the ... Read More
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
"In 2000, Roy Cullimore, a microbial ecologist and Charles Pellegrino, scientist and author of Ghosts of the Titanic discovered that the Titanic --which sank in the Atlantic Ocean 97 years ago -- was being devoured by a monster microbial industrial complex of extremophiles as alien we might expe...

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
I saw this video during the course of listening to TWiP. Is there any parasitic truth behind this phenomenon?

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
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

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
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
The New Scientist has put together a nice collection of articles and information about the swine flu on it's site. 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
The novel human retrovirus XMRV has been associated with prostate cancer and chronic fatigue syndrome. The nucleotide sequence of XMRV isolated from humans indicates that the virus is nearly identical with XMRV produced from a human prostate tumor cell line called 22Rv1. This cell line was deriv...

Hello Vincent and Team TWIV,
I love Virology, and it is with much chagrin that I admit I have only recently started listening to TWIV. However I have tried to mend the error of my ways by: 1) proselytizing the benefits (keeping up-to-date with and... Read More
