To head off a health care disaster, the Infectious Diseases Society of America (IDSA) has developed a plan to combat deadly antibiotic-resistant "super bugs" and is rolling out the multi-pronged plan today, on World Health Day 2011.
Infections are becoming increasingly resistant to existing a... Read More
A deadly superbug was found in about a quarter of water samples taken from drinking supplies and puddles on the streets of New Delhi, according to a new study. Experts say it's the latest proof that the new drug-resistant bacteria, known as NDM-1, named for New Delhi, is widely circulating in th... Read More
Sniffly-nosed kitten-lovers rejoice: A new vaccine could soon banish allergies to cats. The vaccine isn't ready for prime time yet, but a new study finds that the shots are safe, researchers reported March 31 in the Journal of Allergy and Clinical Immunology. They're also effective at reducing a... Read More
Infection with some strains of strep turn deadly when a protein found on their surface triggers a widespread inflammatory reaction. In a report published April 7 in the journal Nature, researchers describe the precise architecture of a superstructure formed when the bacterial protein called M1 ... Read More
Antimicrobial resistance is not a new problem but one that is becoming more dangerous; urgent and consolidated efforts are needed to avoid regressing to the pre-antibiotic era.
For World Health Day 2011, WHO is introducing a six-point policy package to combat the spread of antimicrobial resis... Read More
The more species a habitat holds, the faster pollutants are removed from the water. The first study to rigorously show how biodiversity improves water quality is published today in Nature1. It offers proof that biodiversity helps ecosystems to withstand pressures such as pollution. Read More
A new pathway has been discovered that links a common dietary lipid and intestinal microflora with an increased risk of heart disease, according to a Cleveland Clinic study published in the latest issue of Nature.
The study shows that people who eat a diet containing a common nutrient found i... Read More
I just stumbled upon your podcasts last week and wanted to say that I enjoy them all (TWiV, TWiP, and TWiM). While listening to episode one of TWiM I began to think about the significance of finding human DNA in a bacterial genome. While this discover... Read More
Inspired by Mother Nature, scientists are reporting development of a protective coating with the potential to enable living cells to survive in a dormant condition for long periods despite intense heat, dryness and other hostile conditions.
In a report in Journal of the American Chemical Soc... Read More
Swilling at least three beers a day over several years can increase a person’s risk of stomach cancer if combined with two other unseen risk factors, researchers have found. But oddly, wine and liquor didn’t show the same danger level for this malignancy, the team reported April 4 at a meeting o... Read More
Baruch (Barry) Blumberg, the inventor of the world's first successful anticancer vaccine, has died aged 86. His lifelong quest to fight the hepatitis B virus earned him a Nobel prize and the resulting vaccine prevented tens of millions of deaths from hepatitis and liver cancer.
Researchers have long known that landfills produce methane, but had a hard time figuring out why -- since landfills do not start out as a friendly environment for the organisms that produce methane. New research from North Carolina State University shows that one species of microbe is paving the... Read More
If there is one thing Dr. P.J. Brennan wants his medical students to take away from his class, it's a healthy respect for Staphylococcus aureus, a common strain of bacteria found on skin and in the nose.
It can cause a range of infections, from pimples to endocarditis. The latter is the same ... Read More
At Karlsruhe Institute of Technology (KIT), researchers of the DFG Center for Functional Nanostructures (CFN) succeeded in specifically cultivating cells on three-dimensional structures. The fascinating thing is that the cells are offered small "holds" in the micrometer range on the scaffold, to... Read More
A component of a potential vaccine opens to rearrange proteins and to possibly reveal new targets to prevent HIV infection and AIDS. An international team of researchers from the U.S., Sweden, and France studied the structure and behavior of the HIV envelope protein complex, which could serve as... Read More
Residence time and food contact time effects on transfer of Salmonella Typhimurium from tile, wood and carpet: testing the five-second rule. Salmonella Typhimurium can survive for up to 4 weeks on dry surfaces in high-enough populations to be transferred to foods and S. Typhimurium can be transf... Read More
The persistence and recurrence of H5N1 avian influenza in endemic regions can largely be blamed on movement and infection by migratory birds. Trade in poultry, poultry products and caged birds, and movement of wild birds also account for H5N1 prevalence in these areas. Several recent outbreaks o... Read More
Introductory science courses - in biology, chemistry, math and physics - can be challenging for first-year college, CEGEP and university students. Science 101 courses can make or break a student's decision to venture into a scientific field or even pursue higher education.
"The language, fund... Read More
The ASM has for a number of years been supporting a hand washing campaign. The 31 March 2011 issue of The New England Journal of Medicine has a very good 14-minute-long video on hand washing in clinical care. (Pre-surgical hand scrubbing is not covered.) The video is by Yves Longtin, Hugo Sax, B... Read More
