The recent H1N1 flu pandemic was found to be particularly dangerous to obese people, and a Wayne State University researcher is looking for clues as to why.
Emily Martin, Ph.D., assistant professor of pharmacy practice in the Eugene Applebaum College of Pharmacy and Health Sciences, has begun... Read More
One year on from Europe’s worst recorded outbreak of Escherichia coli infection, governments have made little progress towards improving the monitoring and reporting systems that allowed the crisis to drag on for weeks. The disease, which was spread by contaminated fenugreek sprouts, swept acros... Read More
Renowned influenza virologist Peter Palese has penned an opinion column for the science journal Nature in which he uses his experience in reconstructing the 1918 pandemic influenza virus strain to question the censoring of H5N1 results by the National Science Advisory Board for Biosecurity (NSAB...

The superbugs have met their match.
Conceived at Nanyang Technological University (NTU), it comes in the form of a coating which has a magnetic-like feature that attracts bacteria and kills them without the need for antibiotics.
The killer coating, which has shown to destroy 99 per cent of... Read More
Mothers with IgG antibodies to Toxoplasma gondii at delivery are at risk for later self-harm or suicide, particularly if they have higher titers against the parasite, a Danish study found.
The risk of self-directed violent behavior was increased 1.53-fold (95% CI 1.27 to 1.85, Psk rose to 1.9... Read More
A team of dentists and scientists from Newcastle University are developing a new product from a marine microbe to protect dentures, teeth and gums from bacteria in the mouth.
They are using an enzyme isolated from a marine bacterium Bacillus licheniformis found on the surface of seaweed which... Read More
It was a provocative finding: strange bacteria in a California lake that thrived on something completely unexpected — arsenic. What it suggested is that life, a very different kind of life, could possibly exist on some other planet.
The research, published by a leading scientific journal in 2... Read More
Cholera is an extremely virulent intestinal infection caused by ingestion of the bacterium Vibrio cholerae (V. cholerae). EU researchers elucidated the molecular mechanisms behind expression of virulence genes with important implications for new therapies.

A protein called tubulin (green) accumulates in the center of a nucleus (outlined in pink) from an aging cell. Normally, this protein is kept out of the nucleus with the help of gatekeepers known as nuclear pore complexes. But NIGMS-funded researchers found that wear and tear to long-lived compo... Read More
Thanks so much for your podcasts. I find I am a person who learns best audibly and have just jumped into the science, history, medical and EMS blogs, I Listen to a podcast called SMART EM by a pair of ED docs, and they covered the issue of UTI in Peds. They do jou... Read More
Merry Youle of Small Things Considered has authored a post that looks at Thiomargarita spp.
"Non-motile Thiomargarita was first discovered in 1999 off the Namibian coast, thus was named T. namibiensis. Its cells are large spheres, arranged in chains, each chain enclosed in a mucous sheath. Av... Read More
How do outer membrane proteins (OMPs) make it from the interior of the cell, through the periplasm, and into the outer membrane? In Pseudomonas aeruginosa, Bam and Lol proteins are big helpers that get some, but not all, OMPs where they need to go. The authors of a study in mBio explain this spo... Read More
Due to low uptake of the MMR vaccine across the world, we have seen a dramatic rise in the number of cases of measles and mumps. These have gone against efforts to eradicate these diseases. Perceived safety concerns have led to the rise in uptake of single vaccines and thus for a number of years... Read More
Life in a high-pressured environment with practically nothing to eat might be ok for high-fashion models, but it’s an unlikely lifestyle choice for a single cell whose usual overriding goal is to become two cells. Yet the largest living ecosystem on Earth—the deep biosphere—is comprised of micro... Read More
Cells on the move reach forward with lamellipodia and filopodia, cytoplasmic sheets and rods supported by branched networks or tight bundles of actin filaments. Cells without functional lamellipodia are still highly motile but lose their ability to stay on track, report researchers at the Stower... Read More
Should a study by a team of students from Missouri University of Science and Technology become reality, individuals suffering with diabetes will be able to monitor their blood sugar levels in a more cost-effective way.
Recently, the team of students at the Missouri S&T chapter of iGEM - the ... Read More
Scientists of the Antwerp Institute of Tropical Medicine have breathed new life into a forgotten technique and so succeeded in detecting resistant tuberculosis in circumstances where so far this was hardly feasible. Tuberculosis bacilli that have become resistant against our major antibiotics ar... Read More
The genome nucleotide sequence has been determined of the bacterium GFAJ-1, which has been suggested to survive in high levels of arsenic and in fact incorporate arsenic into macromolecules. The sequence does not address the controversy over whether the bacterium can utilize arsenic. I suppose t... Read More
It’s true! Each year it rains viruses, more than a trillion of them per acre over thousands of forested acres in the USA. This is the work of the airborne arm of the USDA Forest Service, part of their efforts to reduce the devastation to hardwood forests caused by the imported gypsy moth, Lymant... Read More
Scientists' finding is a major breakthrough in understanding a decades-old problem of how bacteria detect environmental changes.
A team of scientists led by Assistant Professor Ganesh S Anand and Professor Linda J. Kenney from the National University of Singapore (NUS) Department of Biologica... Read More
