A blue laser beam turns on a protein that helps this human cancer cell move. Responding to the stimulus, the protein, called Rac1, first creates ruffles at the edge of the cell. Then it stretches the cell forward, following the light like a horse trotting after a carrot on a stick. This new ligh... Read More
Should we only consider bacteria as harmful to our bodies?
Bonnie Bassler is a molecular biologist who has made a stunning discovery: bacteria 'talk' to each other using chemical signals that enable them to act as a unit, mount attacks and coordinate defence. This phenomenon of bacterial com... Read More
Plants associated bacteria play a key role in host productivity and health. These bacteria are phylogenetically diverse and form interactions considered neutral, beneficial or detrimental. A better understanding of these interactions will have a direct impact in agriculture by promoting sustaina... Read More
Almost 1 out of every 3 people in the United States will develop shingles during their lifetime. Despite the approval and recommendation by the FDA of a shingles vaccine for adults over 50, only 16% of American seniors over 60 are vaccinated. Vaccinations are even lower for those aged 50-60. A... Read More
An Ebola outbreak has killed at least 59 people in Guinea, UNICEF said, as the deadly hemorrhagic fever has quickly spread from southern communities in the West African nation.
Experts in the country had been unable to identify the disease, whose symptoms -- diarrhea, vomiting and fever -- we... Read More
Biology researchers from the University of Sydney, working with colleagues from Paul Sabatier Université in Toulouse have found that the brainless slime mold Physarum polycephalum, is able to use its slime trail as a memory device. In their paper published in the Proceedings of the National Acad... Read More
In the current issue of Science, researchers at Michigan State University demonstrate how a new virus evolves, which sheds light on how easy it can be for diseases to gain dangerous mutations.
The scientists showed for the first time how the virus called "Lambda" evolved to find a new way to ... Read More

Bacteria, unlike people, get more orderly when they're in large crowds. In this computer simulation, a few E. coli bacteria start out oriented perpendicular to the walls of a container (blue rods). As they multiply, the growing mass arranges into tidy columns parallel to the container walls (red... Read More
The disruption of the human microbiome through use of antimicrobials is a topic of growing interest among healthcare epidemiologists, not only because it is a major risk factor for C. difficile infection (CDI), but also because it could be a driving force behind the introduction and proliferatio...

The emergence of human infections with avian influenza viruses (H7N9 and H5N1) have raised concerns about the virus gaining the ability to spread person-to-person, potentially causing a deadly pandemic. So far the number of human cases has been limited but the mortality rates have been high. ... Read More
Microscopic pathogens have been causing mass coral die-offs around the world. But now researchers are using high-speed video to spy on the behavior of killer microbes and potentially learn how to better manage coral disease.
“We finally have the tools to watch how bacteria behave in the ocean... Read More
ASM Global Video Challenge submission!
Hello ASM! I am a microbiology graduate student in the Runstadler Lab at MIT. We are an interdisciplinary group of scientists comprising biochemists, ecologists, computer scientists, veterinarians, and microbiologists. Together, our lab studies all aspec... Read More
Whether the microorganisms routinely inhabit the upper troposphere -- perhaps living on carbon compounds also found there -- or whether they were simply lofted there from the Earth's surface isn't yet known. Airborne microbes are of interest to atmospheric scientists, because they could play a r... Read More
During the April 2013 avian influenza A (H7N9) outbreak, more than 130 human infections with H7N9 were reported. Most patients had severe respiratory illness and 44 people have died. Studies suggest that the H7N9 virus has developed resistance to oseltamivir. A human interferon already in use fo... Read More
MBTA officials are planning on using small amounts of dead bacteria will be used - a few ounces, such as the amount in a sugar packet - to test biosensors that were installed in December.
The testing will begin sometime this summer and reaction is decidedly mixed.
MBTA riders voiced their... Read More
The detailed changes in the structure of a virus as it infects an E. coli bacterium have been observed for the first time, report researchers from The University of Texas at Austin and The University of Texas Health Science Center at Houston (UT Health) Medical School this week in Science Expres...

The Rockefeller University's Luciano Marraffini is interested in understanding how bacteria evolve by incorporating DNA sequences from other bacteria or from the environment into their genomes. His research focuses on the mechanisms that control the traffic of DNA molecules between bacteria.
Have you ever wondered why mozzarella bubbling and stretching between pizza slices is so different from the earthy flavors of blue-veined gorgonzola? The diversity of cheeses we love are created by encouraging and manipulating the growth of specific microbes. The American Socie... Read More
SDSU virologists and biologists have identified a highly abundant, never-before-described virus that could play a major role in obesity, diabetes.
Odds are, there’s a virus living inside your gut that has gone undetected by scientists for decades. A new study led by researchers at San Diego S... Read More
