Scientists fool bacteria into killing themselves to survive
Like firemen fighting fire with fire, researchers at the University of Illinois and the University of Massachusetts at Amherst have found a way to fool a bacteria's evolutionary machinery into programming its own death. view more (2008-12-17)
Geologists use biotools to understand geosystems
Geologists are now becoming microbiologists in order to discover how biosystems affect geosystems. view more (2005-10-12)
Stressed cells spark DNA repair missteps and speed evolution
When Dr. Susan Rosenberg, professor of molecular and human genetics at Baylor College of Medicine, first published her finding that the mutation rate increased in bacteria stressed by starvation, sometimes resulting in a rare change that benefited the bacteria, it was controversial. view more (2005-09-16)
Study gives clues about how deadly bacterium gains foothold
How a potentially deadly bacterium that could be used as a bioterrorist tool eludes being killed by the human immune system is now better understood. view more (2006-12-20)
Fine-tuning an anti-cancer drug
Cancer remains a deadly threat despite the best efforts of science. New hopes were raised a few years ago with the discovery that the uncontrolled growth of cancer cells could be thwarted by blocking the action of proteasomes. view more (2009-08-19)
Legume compounds may help cancer treatment
The ARC Centre of Excellence for Integrative Legume Research (CILR) has lodged a complete patent application for compounds to treat cancer. view more (2006-04-10)
Study gives clues about how deadly bacterium gains foothold
How a potentially deadly bacterium that could be used as a bioterrorist tool eludes being killed by the human immune system is now better understood, University of Iowa researchers report in the December issue of the Journal of Leukocyte Biology. view more (2006-12-19)
Researchers map spread of pathogens in the human body
Researchers at the University of Cambridge have discovered a new, more accurate, method of mapping how bacteria spread within the body, a breakthrough that could lead to more effective treatments and prevention of certain bacterial infections. view more (2006-10-23)
Stomach receptor for H. pylori discovered
Scientists have determined that decay-accelerating factor (DAF), a protein found in epithelial cells in the stomach, acts as a receptor for the bacteria Helicobacter pylori. view more (2006-05-05)
Does evolution select for faster evolvers?
It's a mystery why the speed and complexity of evolution appear to increase with time. For example, the fossil record indicates that single-celled life first appeared about 3.5 billion years ago, and it then took about 2.5 billion more years for multi-cellular life to evolve. view more (2007-01-30)
Boston University biomedical engineers find chink in bacteria's armor
Biomedical researchers at Boston University's College of Engineering may have discovered the path toward developing better drugs capable of defeating so-called "superbugs," bacteria that have developed resistance to common antibiotics. view more (2007-09-07)
Important factors involved in the synthesis of starch in plants
The classic model for explaining the biosynthesis of starch in plant leaves has been seriously called in to question. view more (2005-10-24)
Getting to the bottom of the burger bug - Microbiology Today August 2004 issue
Eradicating deadly E. coli O157:H7 from the bottoms of cows may prevent future outbreaks of food poisoning by this famous bug. According to an article in the August 2004 issue Microbiology Today, the quarterly magazine of the Society for General Microbiology, the majority of people with E. coli O157:H7, picked up the infection from cattle, either... view more...

Mars meteorite similar to bacteria-etched earth rocks
A new study of a meteorite that originated from Mars has revealed a series of microscopic tunnels that are similar in size, shape and distribution to tracks left on Earth rocks by feeding bacteria. view more (2006-03-24)
Common bacteria pirate natural mechanism to get inside cells
Bacteria and viruses utilize a natural mechanism to get inside cells and grow, researchers say. view more (2006-01-26)
Anthrax stops body from fighting back, study shows
University of Florida researchers have uncovered how the inhaled form of anthrax disarms bacteria-fighting white blood cells before they can fend off the disease, which kills most victims within days. view more (2005-09-07)
Bacteria control how infectious they become, study finds
The results of a new study suggest that bacteria that cause diseases like bubonic plague and serious gastric illness can turn the genes that make them infectious on or off. view more (2007-04-13)
Detection of Salmonella in 24 hours
The food and drink we consume have to pass strict quality controls. Nevertheless, these measures are not always sufficient, given that sometimes certain foodstuffs can still give rise to food poisoning, most often caused by micro-organisms. view more (2007-02-09)
A salty tale: New bacterial genome sequenced from ancient salterns
Tourists in Spain often stop to ogle the country's many saltwater lagoons, used to produce salt since Roman times. Scientists, too, admire these saltern crystallizers-and even more so, the microbes that manage to survive in such briny environs. view more (2005-12-06)
BGSU biologist trying to crack microscopic code
The Bowling Green State University biologist wants to crack the communication code of proteins, especially the ones whose "talking" aids and abets disease. view more (2006-08-23)
