Biologists at the California Institute of Technology (Caltech) have pinpointed molecular changes that helped allow the global spread of resistance to the antiviral medication Tamiflu (oseltamivir) among strains of the seasonal H1N1 flu virus.
The study—led by David Baltimore, Caltech's Rober... Read More
J. Craig Venter and his colleagues recently announced that they had created the first cell to run on a fully artificial genome. So what's next for this synthetic strain of microscopic Mycoplasma mycoides and the new technology?
The "synthetic cell" achievement has been lauded, condemned and u... Read More
The delicate balance of microbes in the vagina can vary greatly between healthy women, according to a new study led by the UM’s Institute for Genome Sciences. Researchers hope further study will lead to personalized reproductive medicine for women, allowing doctors to tailor each woman’s treatme... Read More

Inputs of dust from the Sahara desert could change the composition of microbial communities in the (sub)tropical eastern North Atlantic say Southampton researchers writing this month in the journal FEMS Microbiology Letters.
When high winds blow over the Sahara, dust particles consisting of s... Read More
The H1N1 pandemic is not yet over although its most intense activity has passed in many parts of the world, the World Health Organization said on Thursday after a review of the flu outbreak by independent experts.
The WHO emergency committee, composed of 15 external advisers, said it remained... Read More
The eyes may or may not be windows to the soul, as the old adage goes, but scientists are reporting evidence that a peek into the eyes of cattle may become the basis for a long-sought test to detect infection with the agent that causes Mad Cow Disease. That test could help prevent the disease fr... Read More
Canadian scientists reported in the FASEB Journal that they discovered that breast milk carries a probiotic that can help alleviate symptoms
of digestive disorders.
Mama's breast milk has been already known to benefit both the mother and her baby. U.S. physicians recommend breastfeeding newb... Read More
Keyboards located in triage and registration areas were found to be more contaminated with bacteria than those in other areas of the Emergency Department at Henry Ford Hospital in Detroit, according to a new study conducted by the hospital.
"Contamination was predominantly found in non-treatm... Read More
Hi Dick and Vincent,
I still love both of your podcasts and was very pleased when Dick referred to Claudius as I love the books about him. This malaria themed podcast made me realize that the historical part of parasitism is so interesting (I'm ... Read More
An experimental vaccine prevented breast cancer in genetically engineered mice, according to a preliminary study in the June 10 issue of Nature Medicine. The vaccine has not been tested in humans.
Though the approach is intriguing, it is far too early to know whether a vaccine could also help... Read More

In a high-risk, urban ambulatory care setting, physicians may use a risk-based screening strategy to test for hepatitis C (HCV) infection, according to the results of a study published online May 20 in the Journal of Viral Hepatitis. This was the first of several studies from the US Centers for ... Read More
After hundreds of years, the most common, basic microscopes still operate by means of the same old hardware: the lens. But what if you could do away with that lens and create a microscope that fits on a cell phone? That’s what researchers led by Aydogan Ozcan at UCLA have developed. Ozcan recent... Read More
Scientists have been hard at work harnessing the power of microbes as an attractive source of clean energy. Now, Biodesign Institute at Arizona State University researcher Dr. Prathap Parameswaran and his colleagues have investigated a means for enhancing the efficiency of clean energy productio...

Bacteria have been sexually promiscuous, swapping genes with gusto, for a very long time. More than 15% of E. coli's genome has arrived via horizontal gene transfer (HGT), with some 200 installments having turned up since it diverged from Salmonella 100 million years ago. And, as you are probabl... Read More
