Sorry I missed your visit to NU- my teaching duties in Evanston prevented it!
Several of my students attended both and had good reports all around. Your work on ISGs sounds like it is coming along well.
I just today l... Read More
This episode: Probiotics could help prevent folate deficiency!
On the issue of antibiotic-resistant bacteria and animals, the first thing that comes to mind is livestock and other farm-based animals that are regularly fed antibiotics as growth promoters, but they are not the only source of resistance. Participants discuss studies showing that non-farm anim... Read More
thank you all for sharing your knowledge in such a comprehensible manner. Thank you also for your stand against bureaucratic censorship in the H5N1 research, and your win. I have two questions. Is H5N1 a highly specific test for a human ge... Read More
When I drafted my article for TakePart (Don’t Panic – Ebola Isn’t Heading For You), I used the term ‘ebolavirus’ throughout, but the editors changed every instance to ‘Ebola virus’. Understanding which term is correct is far more complicated than you might imagine. Read More
I guess it doesn't sting, which is a plus - clearly we need no more stinging/biting/blood-sucking creatures on this earth - but my real wonder is what's next, and why rat heart muscle? Read More
Two papers published this week, and one last month, reveal the pandemic potential of H5N1 "bird flu". One identifies four, another identifies five, genetic changes the virus would have to undergo before it could spread easily in humans, and the third paper suggests some of these changes are alre...

Volcanoes bring death and destruction, but out of the ashes life soon finds fertile ground. A unique experiment is sifting through floating debris from an ongoing volcanic event to see how microbes move in. The results may help in assessing a recent hypothesis that the first life forms may have ... Read More
Alien hunters take note: a global water ocean potentially bigger than all those on Earth combined, is sloshing beneath Titan's icy crust.
Combined with the cocktail of organic chemicals already known to exist on Titan, abundant water could make the moon prime real estate for life – though mor... Read More
The epithelial cells that line the intestines fire bacteria-fighting “bullets” into the gut, Vanderbilt University researchers have discovered.
The findings, featured on the cover of the April 10 issue of Current Biology, represent a new mechanism for defending the body against gut microbes.

Squishing a stack of virus sheets generates enough electricity to power a small liquid crystal display. With increased power output, these virus films might one day use the beating of your heart to power a pacemaker, the researchers behind them say.
Piezoelectric materials build up charge whe... Read More
Scientists at Stanford University and the J. Craig Venter Institute have developed the first software simulation of an entire organism, a humble single-cell bacterium that lives in the human genital and respiratory tracts.
The scientists and other experts said the work was a giant step toward... Read More
Enterococci had been generally regarded as benign commensals, a part of our healthy intestinal microbiota. They were even invited in, being used as probiotics. But then, in the late 1970s, the first multiple drug-resistant strains appeared, and vancomycin-resistant strains followed in 1981. In r... Read More
At first glance it appears to be a minuscule marble spinning around its vertical axis. Look closer, however, and you see a stationary spherical membrane of fluid, just 3 microns across. It is the stuff inside the droplet that is rotating. This self-contained centrifuge has been created by blasti... Read More
