This simulation shows a dynamic molecular model of the bacterial cytoplasm, giving us a spectacular glimpse of the crowded conditions of the interior of a cell over a brief 15-microsecond time span. The model includes 50 of the most abundant types of macromolecules reported in Escherichia coli, ... Read More

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
Nature video captures the essense of the H5N1 debate over the potential publication of two research studies that explore the airborne transmission of the virus between ferrets. Read More
Pablo Rojas' lecture on Microbiology, "Progressive synergism between photography and microbiology — an aesthetic approach," at "Science Slam" in Berlin.
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
A Missouri State Medical Association, led by two Saint Louis University pediatricians, aims to raise awareness about the importance of getting children vaccinated and change the way in which doctors respond to parents' fears of vaccines. The campaign is the focus point of Ken Haller, M.D., assoc... 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
Natural selection is a kind of search engine. Given enough time, and suitably vast populations, it should find the best solutions repeatedly. So why are bacteria still bacteria? And why did all complex life on our planet share an ancestor that only arose once in four billion years? In this lectu... Read More
In as little as 100 generations, yeast selected to settle more quickly through a test tube evolved into multicellular, snowflake-like clusters, according to a paper published in Proceedings of the National Academy of Sciences. Over the course of the experiment, the clusters evolved to be larger,... Read More

Explore Research at the University of Florida: Keith Schneider, an Associate Professor of Food Science and Human Nutrition at the University of Florida, explains what made him want to become a scientist originally, and what he enjoys about his career and research now. Read More
This is a brief scientific simulation displaying our current understanding of how bacteria acquire resistance. It's from the FDA's Center for Veterinary Medicine website. Thanks to Youtube user DrKPW for posting this! Read More
This is a short trailer advertising a new science thriller novel loaded with accurate microbiology. I'm the author, so I'm biased, but reviewers have said about PETROPLAGUE "the science is utterly believable" and it's in "the top five on my best of 2011 list". You can read an excerpt for free ...

In most situations in the wild, animals develop abilities to help them avoid being eaten. The chameleon, for example, can change its color to avoid being seen by predators. What’s less usual, are animals or organisms that develop abilities that do the opposite, i.e. develop traits that encourage... Read More
For a holiday card, my wife and I made a Christmas Tree with bioluminescent ornaments. The video shows how the tree looks in natural light, and then by its own light. The bacterium is Photobacterium leiognathi, isolated by Ned Ruby and Eric Stabb in Hawai'i. This is another example of where mi... Read More
This video examines how the discovery and examination of microbes in meteorites suggests that the planet Mars could have supported life in the same way as Earth. Read More
