If a human cell and a bacterial cell met at a speed-dating event, they would never be expected to exchange phone numbers, much less genetic material. In more scientific terms, a direct transfer of DNA has never been recorded from humans to bacteria.
Until now. Northwestern Medicine researcher... Read More
Los Angeles County health officials are investigating suspicions that Hugh Hefner's legendary Playboy Mansion was ground zero for a rash of mysterious respiratory ailments that afflicted people who attended a fundraiser there earlier this month.

A recent case-control study estimates that the adjuvanted pandemic H1N1 influenza vaccine used in Canada was effective 93% of the time, a substantially higher figure than seen in several other studies and one that has raised some eyebrows among other flu vaccine researchers.
In the study, pa... Read More
Nine out of 10 specialists working in sexual health would give their daughters a private vaccine rather than use the NHS one, according to a survey.
The British Association for Sexual Health and HIV (BASHH) questioned 520 sexual health professionals in the UK.
They are concerned that the N... Read More
Slimy mats of bacteria called biofilms may be the most liquid-repellent materials in nature, researchers have discovered.
“There are a few man-made materials that can perform better, and they have to be made in clean rooms. They’re incredibly expensive and brittle,” said materials scientist A... Read More
Have you heard about the Earth Microbiome Project? Led by the laboratories of Jack Gilbert from Argonne National Labs along with Folker Meyer (Argonne), Janet Jansson (LBNL), Rob Knight (University of Colorado), this is a pioneering effort to characterize the global microbial taxonomic and func...

Scientists have discovered a new way to attack dangerous pathogens, marking a hopeful next step in the ever-escalating battle between man and microbe.
In a paper published online Feb. 10 in the journal PLoS Pathogens, scientists demonstrate that by stopping bacteria's ability to degrade RNA -... Read More
Vincent, I am a huge fan of TWIV and thank you and the others for taking time out of your busy schedule to do the program. I have my B.S. in Biology and Chemistry and would love to go back to school. I read textbooks, listen to podcasts from itunesU and... Read More
Measures to reduce the impact of a flu pandemic, such as closing schools, should not necessarily take place at the beginning of an outbreak, according to computer models.
A report in PLoS Computational Biology argues that starting several weeks later could be more effective.
The researche... Read More
A Canadian doctor reports breastfeeding seems to have transmitted a mother's live-virus yellow fever vaccine virus to her baby.
Dr. Susan Kuhn of the University of Calgary says this incident affirms current recommendations breastfeeding mothers avoid the yellow fever vaccine -- in use since t... Read More
A total of 34 employees at HealthSouth Rehabilitation Hospital tested positive for exposure to tuberculosis last week, but no one has contracted the disease, the hospital CEO reported on Thursday.

Leafcutter ants, signature denizens of New World tropical forests, are unique in their ability to harvest fresh leaves to cultivate a nutrient-rich fungus as food.
Now, this mutualism -- a complicated interplay of ants, fungi and a suite of bacteria -- is coming into sharper focus as a team o... Read More
Researchers have identified a molecule that disrupts RNA degradation in gram-positive bacteria such as the deadly MRSA (Methicillin-resistant Staphylococcus aureus) and the microbe that causes meningitis, according to research published today in PLoS Pathogens.
Treatment with this molecule l... Read More
Quite an idea here, made me think of the part in the Matrix when the nefarious Agent Smith refers to humanity as a "virus" - seems like he was a little off-base. Read More
With the flu now resistant to its two most common medications, doctors and drug developers have grown increasingly puzzled about how to treat the virus. A 900-megahertz magnet is offering some new clues. Biochemists at Florida State University and Brigham Young University have used a 40-ton magn... Read More
A parasite and a virus may be teaming up in a way that increases the parasite's ability to harm humans, scientists at the University of Lausanne in Switzerland and Washington University School of Medicine in St. Louis recently reported in Science.
When the parasite Leishmania infects a human,... Read More
Scientists in Japan have revealed how vancomycin dimers are effective against vancomycin-resistant bacteria.
Vancomycin, a glycopeptide antibiotic, is used to treat bacterial infections in cases when other antibiotics are ineffective. However, the development of vancomycin resistant enteroc... Read More
This photograph depicts the frontal view of a Petri dish within which fungal colonies of Trichophyton rubrum var. granulare had been cultured. Revealed is the colonial morphology, which in the case of T. rubrum is said to be waxy, glaborous, i.e., flat to cottony, and display from a frontal pers... Read More
This silent animation created for Evolution: "The Evolutionary Arms Race" follows the progression of antibiotic resistance. When a sick person takes antibiotics, the drugs begin to kill off the bacteria. But if treatment stops prematurely, it leaves some microbes alive -- the ones with mutations... Read More
