Penn State researchers have found that native pollinators, like wild bees and wasps, are infected by the same viral diseases as honey bees and that these viruses are transmitted via pollen. This multi-institutional study provides new insights into viral infections in native pollinators, suggesti... Read More
TB is on the rise in the last decade, w/ London being rather hard hit. Hopefully this new testing method, promising faster results that could speed up treatment for the infected, provides some much-needed Christmas cheer to those battling this nasty bugger. Read More
For the first time, a microbicide gel -- intended to be used by women during sex -- has been shown to help prevent HIV infection.
In a randomized controlled trial, a gel containing the nucleotide analogue reverse transcriptase inhibitor tenofovir (Viread) reduced the risk of women acquiring H... Read More
Yesterday the Chicago Tribune published my reaction to the four papers on the retrovirus XMRV published this week in the journal Retrovirology. I was quoted as saying ”These four papers are probably the beginning of the end of XMRV and CFS”. I wish to retract this statement and explain my reason... Read More
There is no efficient vaccine against malaria, although nasal and oral vaccination seems to be the most promising and suitable solution in countries where the parasite Plasmodium, which causes the disease, is rife. Researchers from two laboratories in northern France have successfully vaccinated... Read More
A continuación: alucinaciones producidas por antifúngicos; probióticos y Escherichia coli; biología sintética; y esponjas oceánicas.
Scientists from the Alimentary Pharmabiotic Centre (APC), Cork, University College Cork and Teagasc, in Ireland say that specially designed probiotics can modulate the physiology of host fat cells.
According to researchers, the findings could lead to specialised probiotics that have a role in... Read More
Here in her lab on the University of Wisconsin campus, chemist Helen Blackwell and her colleagues are eavesdropping on the chatter among single-celled organisms. For a long time they just listened. Now they actively interrupt the rumble of bacterial communication for a variety of practical purpo... Read More
The stage was set by a coy news release from NASA that hinted at a discovery tied to the search for extraterrestrial life. The blogosphere went wild: Had bacteria been found on one of Saturn's moons, or life of some sort on Mars?
Instead, it was revealed this month in the journal Science that... Read More
Five years ago, Bill Gates made an extraordinary offer: he invited the world’s scientists to submit ideas for tackling the biggest problems in global health, including the lack of vaccines for AIDS and malaria, the fact that most vaccines must be kept refrigerated and be delivered by needles, th...

Researchers from the Chinese University of Hong Kong have succeeded in demonstrating data storage and encryption with bacteria.
While current electronic data storage methods approach their limits in density, the team achieved unprecedented results with a colony of E.coli. Their technique allo... Read More
A team of scientists are currently examining specimens of stomach bacteria from Ötzi the Iceman, who lived about 5,300 years ago, at Stockholm's Karolinska Institute (KI).
Ötzi was discovered by two Germans tourists in September 1991 in the Ötztal Alps, near Hauslabjoch in Italy close to the ... Read More
The development of new antibiotics has slowed to a trickle, just when we need them most. As drug-resistant bacteria are on the rampage worldwide, we find ourselves in a most precarious situation — one not unlike the pre-antibiotic era, before penicillin, when staphylococcal and pneumococcal infe...

Since the first observations that the human retrovirus XMRV is associated with prostate cancer and chronic fatigue syndrome (CFS), new studies have been carried out to determine the role of the virus in these diseases. The results have been conflicting: XMRV (and related retroviruses) have been ... Read More
London is the tuberculosis capital of Western Europe, according to a recent article in the medical journal Lancet, which said that cases there increased 50 percent in the last decade.
The situation is “reminiscent of the unexpected outbreaks of multidrug-resistant tuberculosis in New York an... Read More
A collaborative team of scientists and physicians at the Medical College of Wisconsin and Children's Hospital of Wisconsin uses genetic sequencing to identify and treat an unknown disease.
For the one of the first times in medical history, researchers and physicians at The Medical College of ... Read More
The Fecal Bacteria offers a balanced, integrated discussion of fecal bacteria and their presence and ecology in the intestinal tract of mammals, in the environment, and in the food supply. This new volume covers their use in examining and assessing water quality in order to offer protection from... Read More
Researchers at New York Presbyterian-Weill Cornell Medical Center have discovered a breakthrough experimental treatment for lung cancer.
The treatment is part of a lung cancer vaccine that exposes the body to a protein that the lung cancer produces. This protein production helps the body buil... Read More
An expert group convened by the Pan American Health Organization (PAHO) at its headquarters in Washington, DC, on Dec 17 discussed a possible cholera vaccine for Haiti and suggested developing a global vaccine stockpile.
The cholera vaccine has not been an element of the outbreak response, be... Read More
Much as an anthropologist can study populations of people to learn about their physical attributes, their environs and social structures, some marine microbiologists read the genome of microbes to glean information about the microbes themselves, their environments and lifestyles.
Using a rela... Read More
