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

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

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
