In a new study, Dartmouth researchers describe the structure of a protein called ToxT that controls the virulent nature of Vibrio cholerae, the bacteria that causes cholera. Buried within ToxT, the researchers were surprised to find a fatty acid that appears to inhibit ToxT, which prevents the b... Read More
A newly designed system of identifying molecules for treating hepatitis C should enable scientists to discover novel and effective therapies for the dangerous and difficult-to-cure disease of the liver, says Zhilei Chen, a Texas A&M University assistant professor of chemical engineering who help...

I first posted this list in July 2009. Now Washington University in St. Louis has posted a new list extending from May 2009 to today. Perhaps you're a microbiology student with an interest in growing your library or maybe you're the author of one of these books! Maybe you are just looking for a ... Read More
Influenza A viruses typically cause severe respiratory disease mainly in the very young or the elderly. The 2009 swine-origin H1N1 virus is unusual because it preferentially infects individuals under 35 years of age. We’ve previously noted that being older is a good defense against 2009 H1N1 inf...

Exposure to low levels of antibiotics increases mutations in E. coli and Staphylococcus bacteria hundreds of time more than normal, making the creation of drug-resistance strains more likely, says a paper in today's edition of the journal Molecular Cell.
This finding adds to concerns about an... Read More

Many farmers are faced with the situation of diminishing returns, even where productivity is increasing.
It is not that new technology, such as precision systems, new formulations of fertilisers and chemicals, do not continue to increase productivity, but often the problem is that productivit... Read More
As the U.S. Department of Energy (DOE) works toward developing sustainable sources of clean renewable energy, perennial grasses have emerged as major candidates for the commercial production of cellulosic biofuels from feedstocks. However, little is known about the specific biological traits of ... Read More
BACTERIA that are resistant to antibiotics are becoming disturbingly common in people. More worrying still is that the genes which confer this resistance are also showing up in bacteria found in other animals. When resistant bacteria hop between species, that can increase the rate of evolution a... Read More
Treating herpes in people who are also infected with H.I.V. does not reduce the chances that they will pass on the AIDS virus, according to a new study.
The results were a surprise, said the lead author, Dr. Connie Celum, a professor of global health at the University of Washington. For unkn... Read More
The National Pandemic Flu Service in England is to close because of the sharp decline in cases of the H1N1 swine flu virus. From Thursday anyone who needs medical help because of flu will no longer be able to access anti-viral drugs online or via a helpline. At its peak, 40,000 people a week rec... Read More
Carl Zimmer, author, professor, journalist and podcast host for MicrobeWorld's own Meet the Scientist, is interviewed by Nicola Jones for Nature on what goes in to writing a science book.
"Acclaimed essayist Carl Zimmer has eight popular-science books to his name, on topics from parasites an... Read More
It all started with a brawny, tattooed building contractor with a passion for exotic animals. He was taking biology classes at City College of San Francisco, a two-year community college, and when students started meeting informally early last year to think up a project for a coming science comp...

The first head-to-head comparison of therapeutic monoclonal antibodies produced from plants versus the same antibodies produced from mammalian cells has shown that plant-produced antibodies can fight infection equally well.
Scientists from Washington University School of Medicine in St. Louis... Read More
Vaccination programs against whooping cough may not be fully effective because the bacteria that cause the disease have evolved new strains, a new study has found.
A team of Australian scientists has shown for the first time that two of the most common strains of the Bordetella pertussis bact... Read More
Nature magazine has just launched an iPhone application. It's essentially an eBook reader for the iPhone and iPod Touch that gives all access to Nature and Nature News content as it is published for free until April 30th when presumably they will start charging. It's available in the app store n... Read More
The National Research Foundation (NRF) and two of the local universities will be pumping a total of $206 million over the next 10 years to support a new life sciences centre in Singapore. The Singapore Centre on Environmental Life Sciences Engineering (SCELSE) will focus its study on microbial b... Read More
Could an iPhone application treat acne? A Texas dermatologist seems to think so.
The AcneApp, launched by Houston-based Dr. Greg Pearson, claims to use red and blue light to fight blemishes and improve the health of one's skin.
