An international team led by a University of Cincinnati (UC) researcher has shown how a bacterial community evolves to survive hostile host defenses in the body.
The team, led by Malak Kotb, PhD, chair of UC's of molecular genetics, biochemistry and microbiology department, analyzed the evolu... Read More
Here's a great mother's day song from a biologist's perspective. Musically it is similar to a They Might Be Giants song. Enjoy. Read More
Shoppers who go to the drug store to fill their Plavix prescriptions or pick up a bottle of prenatal vitamins may soon find themselves reconsidering these mundane purchases.
The reason? A new genetic testing kit that will hit the shelves of select Walgreens stores later this month. The test ... Read More
Lamentablemente esta semana El Mundo de los Microbios no estara accesible debido a problemas estudiantiles en nuestra institucion, la Universidad de Puerto Rico. Una huelga estudiantil que ha tenido la universidad bloqueada por los ultimos 19 dias no nos ha permitido el libre acceso a nuestr... Read More
The Patriot Act and the Bioterrorism Preparedness Act were passed in 2001 and 2002. These laws in part cover research on pathogens and toxins thought to have potential as bioweapons.
The Bush administration increased funding for research on such toxins and pathogens—but the laws added a great... Read More
Thirty years ago, the biologist Bruce S. Baker discovered that the gender of a fruit fly is determined not by a hormone, but by the expression of a gene called doublesex in individual cells. Female fruit flies express one form of the gene in their cells, while males express another.
Now, wit... Read More
Until the late 19th century, diphtheria was a gruesome killer with no known cause and many ineffective treatments. In 1874, The New-York Times printed an advertisement for a medicine that would cure not only diphtheria, but also corns, bunions and “pains in the loins and back.” The same year, a ... Read More

University of Michigan researchers say they have identified what appears to be a crucial step in the chain of biological events leading to post-traumatic stress disorder.
Their findings support the idea that exposure to a traumatic event can trigger genetic changes that alter the body's immun... Read More
And here I was worried about whether I would be able to have sushi, fishsticks, or eat at Long John Silver's in a few years. With 5,000 (or more) new species, if I'm willing to eat creatively & have plenty of wasabi/soy sauce on the side, I won't go hungry anytime soon. Buon appetite! Read More
Scientists in France have discovered a new bacterial species in the gut of the fly that transmits African sleeping sickness. They say that the bacteria could be engineered to kill the parasite that causes the disease. According to researchers from IRD, the French Research Institute for Developme... Read More
It seems that cancer & I both resent the unnatural degree of control that clocks exert over our existences - though my resentment manifests as a relatively benign hatred of the alarm's keening wail every morning. Cancer's resentment creates a much more malignant problem, one that science can ho... Read More
US and British forces in Afghanistan have been accused of waging biological warfare on poppy fields to stymie opium crop production.
According to the Telegraph, yields have dropped by up to 90 per cent in some fields. Some Afghan farmers are blaming British and American soldiers for spraying ... Read More
Immortality and uncontrolled cell division are the fundamental differences between cancer cells and normal cells.
A widely held explanation for these differences is that the biological clocks in cancer cells are damaged and can’t regulate cell division in the fashion that they do in normal ce... Read More
Scientists have unraveled the dynamics of a deadly disease that is wiping out amphibian populations across the globe. New findings, published in the Proceedings of the National Academy of Sciences, suggest that infection intensity -- the severity of the disease among individuals -- determines wh... Read More
Learn about PCR and qPCR from world experts on the subject in this 6-part series brought to you over the web. Topics include the history of PCR from Carl Wittwer, an inventor of the LightCycler, discussions on the optimization and chemistry for PCR, and applications including methylation PCR and... Read More

Scientists at Novartis have found bacterial components they hope can be used to develop a vaccine to protect people against a range of dangerous E. coli infections. Certain strains of the bacteria cause diseases such as food-borne illnesses, urine infections and meningitis among newborns... Read More
A team of researchers from Rensselaer Polytechnic Institute will send an army of microorganisms into space this week, to investigate new ways of preventing the formation and spread of biofilms, or clusters of bacteria, that could pose a threat to the health of astronauts.
The Micro-2 experime... Read More
