For years researchers thought that celiac disease — whose sufferers experience an autoimmune reaction to gluten protein — began only in childhood. A new study, however, suggests not only that the number of cases is on the rise, but that the disease can manifest itself in middle-aged and even eld... Read More
City living has obviously influenced human culture—as have often been noted, how you gonna keep ‘em down on the farm after they’ve seen Paree'? But urban life may have also influenced human genes, making the descendants of ancient city dwellers more resistant to disease. That's according to a st... Read More
While the U.S. has made great progress in the prevention and treatment of tuberculosis, the nation has become more susceptible to potential epidemics of multidrug-resistant tuberculosis (MDR-TB), according a study led by Johns Hopkins researchers. Computer simulations show that as TB prevalence ... Read More
A recent analysis by the Centers for Disease Control and Prevention reveals that 1 in 5 gay and bisexual men in the United States is infected with HIV and almost half of those infected are unaware of their status.
Each year about 56,300 Americans become infected with HIV and about 18,000 die ... Read More
Dr. Charles Lee is a FRST Postdoctoral Research Fellow at the Department of Biological Sciences at The University of Waikato. His research into the microbial ecology of extreme environments received a significant financial boost on Friday when the 2010 Marsden Fund grants were announced. The F... Read More
Researchers from the University of Nottingham have discovered that in Staphylococcus aureus infections, bacteria defective in Quorum Sensing (QS) can benefit from opting out of toxin production and can quickly outnumber other bacteria, thereby reducing infection severity.
“This opens up the i... Read More
A University of Oklahoma research team has uncovered a key to arresting the growth of thrush -- a type of oral yeast infection that sickens patients with compromised immune systems, diabetes and newborns as well as healthy individuals, who may contract the disease following antibiotic treatment ...

A trial of a new human monoclonal antibody treatment against rabies has been successful, shaping up as a potential alternative to expensive alternatives derived from horse serum or human blood.
The new cost-effective rabies therapy developed by MassBiologics at the University of Massachusett... Read More
An average 7.8 percent of children under 5 years of age in Taiwan are carriers of multidrug-resistant staphylococcus aureus (MRSA) , a type of bacteria that can cause deadly infections, a study showed Saturday.
Among children under six months, 11 percent carry the bacteria without symptoms, a... Read More
Doctors and infectious bacteria are locked in an arms race. In this ever-escalating battle, the bacteria evolve ways to avoid every drug humans throw at them.
The conflict has intensified lately as more and more bacteria — particularly those lurking in hospitals — become able to resist nearly... Read More

I've been having an enjoyable time on my commute lately catching up with TWiV. Today I listened to #26 (Poxviruses), which included a discussion of Tysabri and PML. I work at Millipore which sells many products that go into a MAb production train, includ... Read More
Simple peptides can organize into bi-layer membranes. This recent finding suggests a “missing link” between the pre-biotic Earth’s chemical inventory and the organizational scaffolding essential to life.
“We’ve shown that peptides can form the kind of membranes needed to create long-range ord... Read More
More people have been infected with West Nile virus in DeKalb County than anywhere else in Georgia this year, officials said.
On Friday, the DeKalb County Board of Health announced five residents have been diagnosed with the disease, including an 87-year-old woman who is still in the hospital... Read More
The world's tiniest nuclear genome appears to have "snipped off the ends" of its chromosomes and evolved into a lean, mean, genome machine that infects human cells, according to research published September 21 by University of British Columbia scientists.
Until recently, E. cuniculi, a parasi... Read More
St. Petersburg, Fla. – (Sept. 22, 2010) – Scientists and researchers seeking additional funding sources for projects that will enhance their research goals now have an alternative resource for the money they need to propel their projects forward: the general public. SciFlies.org, a new non-prof... Read More
The bacteria Salmonella enterica—a common cause of food poisoning—exploits the immune response in the human gut to enhance its own survival.
The strategy, which improves reproductive and transmission success, gives Salmonella a growth advantage over the beneficial bacteria that normally are p... Read More
All known virus particles can be placed into one of two general categories: enveloped or non-enveloped. Viruses that fall into the former category are characterized by a lipid membrane derived from the host cell, and one or more nuclecapsid proteins that interact with the viral genome. A virus t...

Development of an effective vaccine for malaria is a step closer following identification of a key pathway used by the malaria parasite to infect human cells. The discovery, by researchers at The Walter and Eliza Hall Institute, provides a new vaccine target through which infection with the dead... Read More
Pity the poor sea otter.
It's been a struggle for the furry, button-nosed critter to make a comeback since being hunted nearly to extinction along California's coast.
They get chomped by great white sharks. They must scrounge in overexploited waters to find enough shellfish to eat. Their i... Read More
