When NASA's Viking landers touched down on Mars, they were looking for signs of life. Instead, all their cameras showed was a dry, dusty - and entirely barren - landscape.
Or so it seemed. But what the 1976 Viking mission, and every subsequent one, saw was a scene littered with rocks coated w... Read More
Hmm, a burger or salad? We use our brains to judge the nutritional value of foods. Now it seems that slime mold can make similarly complex decisions - despite being just a giant super-cell.

17th Annual Conference for Undergraduate Educators
May 20-23, 2010
Town & Country Resort and Convention Center - San Diego, California
The ASMCUE Steering Committee invites abstract submissions on any aspect of microbiology or biology education for the poster session. This opportunity provi... Read More
One of the most unique fields within microbiology is environmental microbiology and ecology. With discovery literally underfoot, opportunities to identify new organisms and solve challenging puzzles that impact the entire planet make this area of science exciting and fun. These were just some o... Read More
At least 11 linked outbreaks of gastroenteritis with a total of 260 cases have occurred in Denmark in mid January 2010. Investigations showed that the outbreaks were caused by norovirus of several genotypes and by enterotoxigenic Escherichia coli. Lettuce of the lollo bionda type grown in France... Read More
In microbial genomes, genes are typically depicted as linear series of separate regulatory and coding regions. This leads to the assumption that annotations done by computer to predict such arrangements completely describe the coding capacity of bacterial genomes.
However, the more complex o... Read More
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...

Moselio Schaechter of the Small Things Considered blog reviews the surprising findings in the paper "Energized outer membrane and spatial separation of metabolic processes in the hyperthermophilic Archaeon Ignicoccus hospitalis" published in the recent Proceedings of the National Academy of Scie...

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
You expect the hospital to be one of the cleanest places around. But it can actually be a safe haven for super germs that can get you very, very sick. These germs are so hard to treat that scientists are now looking to the sea for solutions.
Sharks are considered to be some of the most danger... 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...
