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
There is much interest in the role of nutrients and micronutrients in the support of host defense against infections. However, there is controversy in the ability of supplements to help prevent or treat infections. Speakers discuss research on the role of vitamin D supplements to prevent and/or ... Read More
Dr. Owen White of the Institute for Genome Sciences at the University of Maryland School of Medicine describes how the Data Analysis & Coordination Center supports the Human Microbiome Project, working with sequencing data from microbiology researchers.

Patients getting medical care can catch serious infections called healthcare-associated infections (HAIs). While most types of HAIs are declining, one -- caused by the bacterium Clostridium difficile --continues to grow. C. difficile causes diarrhea linked to 14,000 American deaths each year. Pa...

Judith Klatt is a doctoral student at the Max Planck Institute for Marine Microbiology in Bremen. She's also a mother, keen to fulfilf both her roles with equal vigor. She's being helped by a foundation set up by Nobel laureate Christiane Nüsslein-Volhard.It provides financial support so Judith ... Read More
This video looks at the microbial origins of the Black Death.
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
Wyss researchers have engineered photosynthetic bacteria to produce simple sugars and lactic acid, an innovation that could lead to new, environmentally friendly methods for producing commodity chemicals in bulk. Because the production methods use photosynthesis -- the process by which living th... Read More
It's not necessarily microbiology, but the fungus gnat does feed on algae and can be controlled in the garden with Bacillus thuringiensis, the bacterium that makes Mosquito Dunks effective.
Nevertheless it's a cool video. What I would like to know, and can't seem to find with a Google search,... Read More
In this video from India's NDTV, reporters address growing public anger against the World Health Organisation (WHO) for reportedly making swine flu pandemic bigger than it really was. Health experts in India say this isn't the first time WHO has pushed for programmes, even though they are not ne... Read More
Scientists who advised the World Health Organization on its influenza policies and recommendations—including the decision to proclaim the so-called swine flu a "pandemic" had close ties to companies that manufacture vaccines and antiviral medicines like Tamiflu, a fact that WHO did not publicly ...

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
Did you ever have a question where you thought microbes were at fault but weren't certain... A group of faculty from Wando High School from Mount Pleasant South Carolina recently visited the laboratory of Dr. Michael Schmidt, a professor of Microbiology at the Medical University of South Caroli...

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
Hazel Barton, Ph.D of Northern Kentucky University explains that microorganisms actually form the basis of nearly all the ecosystems that you will find in a cave. Read More
Ben-Yehuda's group identified a previously uncharacterized type of bacterial communication mediated by nanotubes that bridge neighboring cells. The researchers showed that these nanotubes connect bacteria of the same and different species. Via these tubes, bacteria are able to exchange small mol... Read More
