While genetics likely play a role in some instances of colorectal cancer, a new study in mice suggests gut bacteria could also influence development of intestinal tumors. Researchers from the Icahn School of Medicine at Mount Sinai found that giving antibiotics to mice to disrupt their microbial... Read More
In this blog post, I show a science-cartoon by the great "Beatrice the Biologist" that illustrates an important point in my freshman introductory cell and molecular biology course: no matter how tired we might be, we are incredibly busy on a cellular level! Beatrice is a fine artist who underst... Read More
A rare, recently discovered microbe that survives on very little to eat has been found in two places on Earth: spacecraft clean rooms in Florida and South America.
Microbiologists often do thorough surveys of bacteria and other microbes in spacecraft clean rooms. Fewer microbes live there tha... Read More
This episode: Non-pathogenic Clostridium difficile strains can protect hamsters against their disease-causing bacterial siblings!
(7 MB, 7.5 minutes)
When hamsters were colonized with toxin-free strains of C. difficile, they were better able to resist infection b... Read More
Creating synthetic organisms with specially-tailored genomes is a long way off, but the first synthetic eukaryotic chromosome is a big step forward.
Humans have been using what they know about the biological world to make stuff for centuries—from beer to antibiotics. But, what if you could ma... Read More
On a sunny day in 1998, Maura Gillison was walking across the campus of Johns Hopkins University in Baltimore, Maryland, thinking about a virus. The young oncologist bumped into the director of the university's cancer centre, who asked politely about her work. Gillison described her discovery of... Read More
A decades long fight over cleaning up one of the nation's most contaminated riverbeds has posed a difficult question: how to safely remove enough toxic material from New Jersey's Passaic River to fill two MetLife Stadiums.
The federal government is moving forward with long-stalled efforts to ... Read More
The Foldscope is a fully functional microscope that can be laser- or die-cut out of paper for around 50 cents.
This bookmark-sized microscope can be assembled in minutes, includes no mechanical moving parts, packs in a flat configuration, is extremely rugged and can be incinerated after to s... Read More
I have found that students become involved, energized, and enthusiastic when I give them opportunities to explore topics in my classes using their own creative approaches and interests. So this semester, in my Biology 111 course at the University of Puget Sound, I found that students explored f... Read More
In this blog entry, I explore how students can use their creativity to learn microbiology in innovative and often artistic ways. It makes learning more personal! Read More
A bill to track drug-resistant infections has been introduced in Florida, inspired in part by FRONTLINE’s Hunting the Nightmare Bacteria.
The bill, sponsored by Rep. Janet Adkins, a Republican, requires the state health department to maintain an online record of the type and location of any a... Read More
SAN FRANCISCO – Swallowing pills containing a concentrate of fecal bacteria successfully stops recurrent bouts of debilitating Clostridium difficile (C. diff) infection by rebalancing the bacteria in the gut, suggests a study being presented at the IDWeek 2013™ meeting today.
Infection from C... Read More
Despite surgeons’ best efforts, bacteria often manage to sneak onto medical implants such as bone screws, where they can cause severe infections. Research published today in Nature Communications suggests that using fluorescent antibiotics could reveal such infections before they become too seve... Read More
Could the microbes that inhabit our guts help explain that old idea of "gut feelings?" There's growing evidence that gut bacteria really might influence our minds.
"I'm always by profession a skeptic," says Dr. Emeran Mayer, a professor of medicine and psychiatry at the University of Californ... Read More
A North Dakota company that discovered an antibody technology while trying to cure flocks of dying geese is using its research for a more warm and fuzzy purpose: saving puppies.
Early tests performed on about 50 puppies in seven U.S. states for Grand Forks-based Avianax have resulted in a 90 ... Read More
Influenza viruses evolve rapidly, making it hard to develop protective vaccines against them. Despite a great deal of effort, scientists have found it difficult to forecast which way the virus’ evolution would take it. Now, thanks to improvements in our ability to study viruses and a new mathema... Read More

A new device from Macquarie University can manipulate objects as small as 50 nanometers wide — about a thousandth of the width of a human hair and small enough to allow direct manipulation of a single viral capsule.

The death last week of a Florida man from an uncommon flesh-eating bacterium was the state's ninth so far this year.
The bacterium is in the same family as those that cause cholera.
Henry Konietzky, 59, of Palm Coast, Fla., died Sept. 23 after setting crab traps two days earlier in the riv... Read More
Virulent, drug-resistant forms of E. coli that have recently spread around the world emerged from a single strain of the bacteria, not many different strains, as has been widely believed.
The strain—which causes millions of urinary, kidney and bloodstream infections a year—could have a far gr... Read More
