A new study led by researchers at NYU Langone Medical Center is shedding new light on the action of Rho, a key regulatory protein in E. coli and many other bacteria. The study, published in the Jan. 14, 2010 issue of Nature, reveals a new paradigm to understand the molecular principles of gene t... Read More
A top World Health Organization official dismissed charges Thursday that the agency exaggerated the threat posed by the H1N1 virus and that it had been unduly influenced by the pharmaceutical industry to issue dire warnings about the swine flu pandemic.
"The world is going through a real pand... Read More
About 100 million years ago, the bacterium Wolbachia came up with a trick that has made it one of the most successful parasites in the animal kingdom: It evolved the ability to manipulate the sex lives of its hosts.
"When it developed this capability, Wolbachia spread rapidly among the world'... Read More
It's not thinking in the way humans, dogs or even birds think, but new findings from researchers at the University of Tennessee, Knoxville, show that bacteria are more capable of complex decision-making than previously known.
The discovery sets a landmark in research to understand the way bac... Read More
Researchers from the University of York reported in Science online today that they have created the first genetic map for the medicinal herb Artemisia annua, which contains an extract called artemisinin that's used to help treat some forms of malaria.
Through deep sequencing of a hybrid plant... Read More

A year ago, Michael Taylor was sitting in his office at George Washington University, considering a basic mission of the federal government: making sure food is safe. He'd devoted his career to food safety, working in and out of government, and he was finally in academia where he could think dee... Read More

Oryzae is back and this time he's hanging out with the "habitual skin microbes." Note that the subtitles around 0:46 are a little confusing and may be incorrect, possibly due to a translation issue. Since I do not understand Japanese I can't tell for sure.
To learn more about microbes... Read More
U.S. Department of Energy Secretary Steven Chu today announced the investment of nearly $80 million under the American Recovery and Reinvestment Act for advanced biofuels research and fueling infrastructure that will help support the development of a clean sustainable transportation sector. The ... Read More
Biological warfare and bioterrorism are as old as fourth-century BCE Scythian fighters wiping their arrows on decomposing bodies before shooting them at their enemies and as new as ricin toxin delivered to a US Senate mailroom in 2004. They consist of using viruses, bacteria, fungi and other tox... Read More
It is known that viral "squatters" comprise nearly half of our genetic code. These genomic invaders inserted their DNA into our own millions of years ago when they infected our ancestors. But just how we keep them quiet and prevent them from attack was more of a mystery until EPFL researchers re... Read More
One California pet frog breeder may be the source of a nationwide salmonella poisoning outbreak that has lasted for eight months.
Cases of salmonella that have sickened people throughout the United States have been liked to African dwarf frogs from one breeder. The pet frogs were subsequently... Read More
"Curiosidades de la microbiologia" (Curiosities of the microbial world) is a microbiology blog writen in spanish language. The aim of the blog is academic and divulgative. It was designed as a support tool for graduate students in life science like Biology, Biochemistry, Biotechnology, Medicine,... Read More
Bacteria such as methicillin-resistant staphylococcus aureus (MRSA) are a growing problem in hospitals and researchers are anxious to understand how they evolve.
Norwegian researchers said they had found little sign of such microbes in the feces of polar bears in the remote Arctic, suggesting... Read More
Nestlé USA said Wednesday that two samples of its Toll House refrigerated cookie dough made at a Virginia factory tested positive for E. coli bacteria this week despite rigorous safety measures put in place after a recall of the product last summer.
Nestlé also said the tainted dough had not ... Read More
The chromosomal DNA of several mammals has been found to contain sequences related to the nucleoprotein (N) gene of bornaviruses, enveloped viruses with a negative-strand RNA genome. I am amazed by this finding. How did bornaviral DNA get in our chromosomes, and what is it doing there? Read More
Soybean, one of the most important global sources of protein and oil, is now the first legume species with a published complete draft genome sequence. The sequence and its analysis appear in the January 14 edition of the journal Nature. The research team comprised 18 institutions, including th... Read More
Salmonella bacteria on lettuce penetrate the leaves to enter inner tissues via stomata, while also actively swimming toward photosynthetically produced nutrients, according to Shlomo Sela and other members of an Israeli research team.
Although other bacterial plant pathogens also enter plant ... Read More
