Note: Episode 144 is now available too. Sorry about that. Not sure what went wrong there, but it is regrettable.
A minor player in the gut, Clostridium scindens,... Read More
In a study published in Nature, the team from University College London and the Medical Research Council Laboratory of Molecular Biology explains how HIV uses molecules inside host cells in an infected person to avoid alerting the body’s innate immune system (IIS) – cells and mechanisms that for...

Just in time for “Get Smart about Antibiotics Week,” I had a refreshing experience recently, working in a different rural hospital. Over that week, I didn’t see one patient with “superbugs” other than the occasional MRSA. No one had the now scarier Gram negative bugs known as ESBLs (extended spe... Read More
Purdue University researchers successfully eliminated the native infection preferences of a Sindbis virus engineered to target and kill cancer cells, a milestone in the manipulation of this promising viral vector.
"This virus had been known to be a good vector for delivering therapeutic cargo... Read More
Since its appearance in the U.S. seven years ago, white-nose syndrome has decimated bat populations across eastern North America. Scientists say they've determined the culprit—a soil-dwelling fungus called Pseudogymnoascus destructans—and now they're investigating novel ways to stop it, includin... Read More
Medical investigators for the first time have confirmed the MERS coronavirus in a camel, one belonging to a Saudi man also ill with the new virus, providing a critical clue into the virus's animal hosts and transmission, a top Saudi health official and an international disease expert said on Mon...

In managing bloodstream infections, minutes count, and delays in treatment or administering the wrong antibiotic can kill a patient. In mBio today, scientists from bioMérieux, Inc. describe a new method that could cut hours off the time it takes to diagnose blood infections while also eliminatin... Read More
While studying for a PhD at the University of Waikato graduate Ron Xavier discovered a passion for communicating complex science to the public.
Thanks to the collaborative work he completed during a University of Waikato Doctoral Scholarship in microbiology, Ron is now employed by AgResearch ... Read More
A dedicated website for sharing biology papers before peer review leaves journals divided.
What are biologists so afraid of? Physicists, mathematicians and social scientists routinely post their research to preprint servers such as arXiv.org before publication, yet few life scientists follow ... Read More
The U.S. Food and Drug Administration today approved the first adjuvanted vaccine for the prevention of H5N1 influenza, commonly known as avian or bird flu. The vaccine, Influenza A (H5N1) Virus Monovalent Vaccine, Adjuvanted, is for use in people 18 years of age and older who are at increased r... Read More
Biologists dissected tissue samples from an oarfish carcass found in California and discovered the creature was hosting quite a few parasites.
“Our findings say that these are actually majorly parasitized fish,” says Armand Kuris, professor of zoology at the University of California, Santa Ba... Read More
The virus that has killed nearly 800 bottlenose dolphins off the East Coast has turned up in four whales that have washed ashore, a potentially troubling development if it is shown to be the cause of their deaths, a government marine expert said Thursday.
But it is too early to know whether c... Read More
Researchers at Case Western Reserve University and Cleveland Clinic Lerner Research Institute have discovered recent genetic mutations in a parasite that causes over 100 million cases of malaria annually -- changes that may render tens of millions of Africans who had been considered resistant, s...

What's a virus to do when it finds itself in an inhospitable environment such as hot water? Coating itself in glass seems to not only provide protection, but may also make it easier to jump to a more favorable location to spread.
Researchers led by a group from the Center for Life in Extreme ... Read More
Scientists are reporting an advance in smartphone-based imaging that could help physicians in far-flung and resource-limited locations monitor how well treatments for infections are working by detecting, for the first time, individual viruses. Their study on the light-weight device, which conver... Read More
Bioengineers at the University of California, San Diego have used the genomic sequences of 55 E. coli strains to reconstruct the metabolic repertoire for each strain. Surprisingly, these reconstructions do an excellent job of predicting the kind of environment where each strain will thrive, the ... Read More
Delivering healthy bacteria in a pill could help patients harboring out-of-balance microbial communities. Yogurt eaters already know that not all bacteria are bad for you. They may not realize that some bacteria are so important that one day people may fight off disease with pills filled with ba... Read More
The Kartchner caverns in southeast Arizona are famous for their spectacular limestone rock formations, created by groundwater seeping and dissolving bedrock compounds over thousands of years. For all their beauty, the caverns are extremely harsh environments with no sunlight and precious little ... Read More
The students, at the University of California at Santa Barbara, were all sickened within a three-week period last month with the disease, a sometimes fatal illness that can affect the brain or the blood, according to a spokeswoman for the Santa Barbara County Department of Public Health.
