A panel of university and private-sector scientists urged Congress not to overregulate laboratories that handle deadly pathogens, saying it could have a chilling effect on research. In a 161-page report, a committee of the National Research Council says the best protection against deliberate mis... Read More
ABC News video on the late Malcom Casadaban, a University of Chicago researcher who passed away after exposure to Yersinia pestis.

If you’ve ever suffered through a bad case of food poisoning, you’ll be glad to know that Naval scientist Patricia Guerry has made a breakthrough that may dramatically reduce the odds that you’ll have to relive this miserable experience. Read More
As scientists work toward making genetically altered bacteria create living "circuits" to produce a myriad of useful proteins and chemicals, they have logically assumed that the single-celled organisms would always respond to an external command in the same way.
Alas, some bacteria apparently... Read More
A powerful fish-killing toxin could have cancer-killing properties as well, according to collaborative research led by Agricultural Research Service (ARS) microbiologist Paul V. Zimba and chemist Peter Moeller of the U.S. National Oceanic and Atmospheric Administration (NOAA). The toxin, called ... Read More
Stephanie Smith, a children’s dance instructor, thought she had a stomach virus. The aches and cramping were tolerable that first day, and she finished her classes.
Then her diarrhea turned bloody. Her kidneys shut down. Seizures knocked her unconscious. The convulsions grew so relentless tha... Read More
The exact number of bacteria living in or on humans isn't known, though it is estimated to be around a trillion. In any case, the number of microbial cells in the human body outnumbers the human ones by a factor of 10. Those symbiotic microbes endow humans with otherwise unattainable metabolic c... Read More
In a major scientific breakthrough, scientists of the School of Biotechnology, Banaras Hindu University, have isolated a group of
bacteria that degrades lignite coal (low energy producing coal) to produce methane gas for increased fuel efficiency.
While the isolation of the special group of... Read More
Americans Elizabeth H. Blackburn, Carol W. Greider and Jack W. Szostak won the 2009 Nobel Prize in medicine on Monday for discovering a key mechanism in the genetic operations of cells, an insight that has inspired new lines of research into cancer.
It was the first time two women have been a... Read More
A pathogen is a an organism (bacterium, virus, parasite) that causes disease in another organism. According to data from the U.S. Centers for Disease Control and Prevention (CDC), known pathogens account for an estimated 14 million illnesses, 60,000 hospitalizations, and 1,800 deaths each year i...

Researchers have developed a new method for studying bacterial swimming, one that allows them to trap Escherichia coli bacteria and modify the microbes' environment without hindering the way they move.
The new approach, described this month in Nature Methods, uses optical traps, microfluidic ... Read More

A very important message to women who are pregnant. Listeria monocytogenes is very dangerous for anyone who is immunocompromised and it is one of few bacterial pathogens that can cross the fetal-placenta barrier and infect the fetus, usually resulting in fetal death. The USDA produced this vid... Read More

A pilot program is allowing some Maryland creameries to manufacture and sell raw milk cheese. This video takes you to Chapel County Creamery to see the unpasteurized process first hand. Read More
Researchers from Brown University and McGill University have discovered that the natural killer, or NK cells, help prevent T cells from over-responding when a virus hits. This balance helps prevent T cells, which ordinarily serve the immune system, from causing harm.
Natural killer, or NK cel... Read More
"Michael Storrie-Lombardi, PhD, from Kinohi Institute (Pasadena, CA), and Birgit Sattler, PhD, from the University of Innsbruck, Austria, used laser-induced fluorescence emission (L.I.F.E.) imaging to detect red and infrared fluorescence activity produced by cyanobacteria present in the ice of f...
