In certain social circles, it's not what you know, but who you know that counts. The same seems to be true of the gene switches that turn on cancer cells.
One way cells turn genes on and off is via small RNA molecules. In cancer, the usual pattern of microRNA production is disrupted. But as s... Read More
On the grounds of Uganda’s biggest AIDS clinic, Dinavance Kamukama sits under a tree and weeps.
Her disease is probably quite advanced: her kidneys are failing and she is so weak she can barely walk. Leaving her young daughter with family, she rode a bus four hours to the hospital where her ... Read More
We are not alone -- even in our own bodies. The human gut is home to 100 trillion bacteria, which, for millions of years, have co-evolved along with our digestive and immune systems. Most people view bacteria as harmful pathogens that cause infections and disease. Other, more agreeable, microbes... Read More
A team of University of California, San Diego School of Medicine researchers has discovered that common intestinal bacteria appear to promote tumor growths in genetically susceptible mice, but that tumorigenesis can be suppressed if the mice are exposed to an inhibiting protein enzyme.
The re... Read More
Change is a-coming. Thats what Rino Rappouli (of Novartis Vaccines and Diagnostics in Siena, Italy) and Antonio Cassone (of the Department of Infectious, Parasitic and Immunomediated Diseases at the Istituto Superiore di Sanita Rome) argue in a new Perspectives piece accepted for the inaugural ...

In the Nº 102 of the "El podcast del microbio" I discuss the panspermia theory and the results of the satellite Foton M3 experiment. En el p... Read More
Every year, thousands of people in Arizona contract an infection while being treated in a hospital.
The illness, which sometimes is fatal, may come from a doctor's unwashed hands, dirty hospital scrubs, unclean medical instruments or even bacteria found on the patient's skin.
But unlike in... Read More
When exactly did oxygen first appear in Earth’s atmosphere? Although many physical and chemical processes are thought to be responsible for that profound transformation, scientists have tried to answer at least part of that question by looking for the origin of oxygenic photosynthesis — the pro...

Three-quarters of children vaccinated against meningitis C lose their protection against the disease by their early teens, research suggests. The Oxford team which did the work says its findings fuel calls for a booster jab to be offered to adolescents. The study of 250 children aged six to 12, ... Read More
Researchers say that a dry, inhalable vaccine developed for measles prevention may also help pave the way for the inexpensive treatment of a range of other illnesses.
More immediately, news of the vaccine should be especially welcomed by less-developed nations, where there is more limited acc... Read More
Bacterial spores, the most resistant organisms on earth, carry an extra coating of protection previously undetected, a team of microbiologists reports in the latest issue of the journal Current Biology. Their findings offer additional insight into why spores of the bacteria that cause botulism, ... Read More
Having upped my daily dose of podcasts I stumbled upon This Week In Science. The latest show (http://www.twis.org/audio/2010/03/09/438/) they mentioned something that probably comes within your sphere of interest, namely the fin... Read More

The US Food and Drug Administration recently recommended that administration of Glaxo SmithKline’s Rotarix vaccine, which protects against rotavirus infection, be suspended after an independent research group found that the vaccine contains DNA of porcine circovirus type 1. Now the FDA reports f... Read More
Last April, a strange new virus was sickening and killing patients in Mexico. It showed up in two children at a California clinic. Identified as a new form of H1N1, or swine flu, it quickly became a test of the USA's preparations for an epidemic and the public's ability to cope with fear of the ... Read More
Dangerous bacteria may be rafting their way to a beach near you. New research reveals that, just like a rat clinging to a piece of floating wood after a flood, pathogenic microorganisms can set up shop aboard drifting bits of fish feces and other debris and ride them to far-flung destinations. U... Read More
Members of a Food and Drug Administration advisory committee meeting Friday urged physicians to continue using both commercial rotavirus vaccines despite evidence that both carry trace contaminants from a harmless pig virus. The panel did not take a formal vote on a recommendation, but a majorit... Read More
A lake of asphalt may be the closest thing on Earth to the hydrocarbon seas on Saturn's moon Titan -- and our asphalt lakes are teeming with microbial life.
Not only could these findings help in the search for aliens in our own solar system, but they could provide insight into the evolution ... Read More
Anthrax-causing bacteria can be engineered to shed their invisibility cloaks, making it easier for the immune system to eradicate it, according to a new study published in Microbiology. The work could lead to new measures to treat anthrax infection in the event of a biological warfare attack.
