Here's a nice edu resource-related video about the biology of bacteria that the team over at SciVee.tv posted. It looks like it originally came from Maryland Public Television. This is probably good for many intro to microbiology type courses and high school level life science classes. Read More
Wanted (soon): observations from environment-minded citizens that will allow science to study biodiversity at a planetary level in a massive, comprehensive virtual observatory of historic importance.
The online information system for life on Earth, now under construction, will take its place ... Read More

Scientists say the symbiotic relationship between algae and corals is breaking down:
"Corals, it appears, have a genetic complexity that rivals that of humans, have sophisticated systems of biological communication that are being stressed by global change, and are only able to survive based o... Read More
Scientists are now be able to gain a reasonably accurate picture of the ocean's health and productivity about every week, all over the planet.
Researchers from Oregon State University, NASA and other organizations said today that they have succeeded for the first time in measuring the physiol... Read More
Julia A. Segre and her colleagues are on an expedition of sorts, collecting information about the diversity of species in an ecosystem.
But Dr. Segre isn’t off trapping insects in the woods somewhere or scooping up samples of plankton on an ocean voyage. The species she and her colleagues ar... Read More
Current tests to identify specific strains of infectious prions, which cause a range of transmissible diseases (such as mad cow) in animals and humans, can take anywhere from six months to a year to yield results – a time-lag that may put human populations at risk.
Now, a group of scientists... Read More
Pregnant women who are deficient in vitamin D may be at increased risk for developing bacterial vaginosis, a vaginal infection that may have harmful effects on the pregnancy, according to a report in The Journal of Nutrition.
Bacterial vaginosis is caused by an imbalance of the bacteria norma... Read More

Vancomycin resistant enterococci (VRE) have been found in sewage sludge, a by-product of waste-water treatment frequently used as a fertilizer. Researchers writing in the open access journal Acta Veterinaria Scandinavica point out the danger of antibiotic resistance genes passing into the human ... Read More
The health of our skin — one of the body's first lines of defense against illness and injury — depends upon the delicate balance between our own cells and the millions of bacteria and other one-celled microbes that live on its surface. To better understand this balance, National Institutes of He... Read More
Intestinal permeability and an overgrowth of bacteria in the small intestine are both associated with nonalcoholic fatty liver disease (NAFLD). These findings are revealed in a new study in the June issue of Hepatology, a journal published by John Wiley & Sons on behalf of the American Associati... Read More
The UK's National Center for Biology Eduction has an interesting experiment involving toilet paper, hot water and oyster mushroom starter culture.
"Gastronomes will no doubt be aware of the presence of an increasing range of exotic mushrooms on the supermarket shelves. In the Far East, oyster... Read More
Here's a nice demonstration video by Dr. Conor O'Bryne from the Dept. of Microbiology at National University of Ireland, Galway, showing how to perform a serial dilution on a liquid food sample (in this case raw unpasteurised milk). The raw milk sample is diluted down to 1/1000 in a sterile dil... Read More
Research has revealed a novel way to tinker with the life cycle of parasitic worms—suggesting new avenues to attack or prevent infections such as hookworm that plague an estimated 1.3 billion people worldwide.
The findings, published May 25, 2009, in the Proceedings of the National Academy o... Read More
"Synthetic biology has already delivered engineered organisms that can churn out a malaria drug, cook up an ideal biofuel or act as biosensors, but questions remain about how such organisms can be eliminated from the environment after they have performed their task.
A team of US biotechnologi... Read More
From December 1, all manufacturers must test source water for the germs each week as is currently required for finished bottled water products. If tests prove positive for E. coli, companies must explain in writing how they eliminated the bacteria and retest samples before use.
According to a... Read More
