An Earth Day Shout-out to Microbes

So another Earth Day has come and gone. How did you spend yours? If you spent the entire day asleep, you used about half a kilogram of oxygen.

All of a sudden the Stilton seemed even sharper. The question ... Read More

How E. coli could help tackle those sweet cravings

The study researchers found that placing a small, detoxified amount of E. coli in the guts of mice led to an increase in levels of leptin - known as the "satiety hormone."

Within 7 days of the increase, the number of sweet taste receptors on the rodents' tongues reduced, diminishing their ap... Read More

Chemistry: A festive ferment

Rare is the holiday meal that does not owe many of its pleasures to invisible cooks with tongue-twisting names. Do you enjoy charcuterie and pickles? Bread with cultured butter? A drizzle of vinaigrette on this or that? A bit of cheese? Some chocolates? Wine, beer or cider? Then raise a glass to... Read More

Transmission of Ebola virus

As the West African epidemic of Ebola virus grows, so does misinformation about the virus, particularly how it is transmitted from person to person. Ebola virus is transmitted from human to human by close contact with infected patients and virus-containing body fluids. It does not spread among h... Read More

Virologists, start your poliovirus destruction!

I have worked on poliovirus for over thirty-six years, first as a posdoctoral fellow with David Baltimore in 1979, and then in my laboratory at Columbia University. The end of that research commences this year with the destruction of my stocks of polioviruses. Read More

Dear Doctors


This one is a bit more tricky; both Giardia and Cryptosporidium are possible. The symptoms are more those of Cryptosporidium, so that would be my semi-educated guess. Most of that education comes through you, with some help of some CDC... Read More

Human Microbiome Report & Infographic

The human microbiome, the collection of trillions of microbes living in and on the human body, is not random, and scientists believe that it plays a role in many basic life processes. As science continues to explore and better understand the role of the human microbiome. A new report from the Am... Read More

Incidence of asymptomatic human influenza A(H5N1) virus infection

When virologists Fouchier and Kawaoka were isolating avian influenza H5N1 viruses that could transmit among ferrets by aerosol, there was consternation from some quarters that such viruses might escape from the laboratory and cause a pandemic in humans. Part of the fear came from the fact that t... Read More

Reducing antibiotic requests from patients with viral infections

For anyone interested in Antibiotic Awareness Week, a big part of the story is that patients (or their parents) demand antibacterials even for viral infections. And doctors often comply, just to get rid of them (the patients, that is). This high-resolution PDF can be printed out for waiting ro... Read More

De-discovering pathogens: Viral contamination strikes again
