NYU scientists discover dangerous new method for bacterial toxin transfer
Scientists have discovered a new way for bacteria to transfer toxic genes to unrelated bacterial species, a finding that raises the unsettling possibility that bacterial swapping of toxins and other disease-aiding factors may be more common than previously imagined.   view more (2009-01-07)

Evolution in action: Our antibodies take 'evolutionary leaps' to fight microbes
With cold and flu season in full swing, the fact that viruses and bacteria rapidly evolve is apparent with every sneeze, sniffle, and cough. A new report in the January 2009 issue of The FASEB Journal, explains for the first time how humans keep up with microbes by rearranging the genes that make... view more (2009-01-06)

Understanding Extinct Microbes May Influence the State of Modern Human Health
The study of ancient microbes may not seem consequential, but such pioneering research at the University of Oklahoma has implications for the state of modern human health. Cecil Lewis, assistant professor in the Department of Anthropology, says results of this research raise questions about the... view more (2009-01-06)

Uncultured bacteria found in amniotic fluids of women who experience preterm births
Researchers from Case Western Reserve University and Yale University have made a significant advancement in understanding the cause behind why some pregnant women suffer from inflammations in the inner womb without any signs of an infection.   view more (2009-01-05)

Viruses, start your engines!
Peering at structures only atoms across, researchers have identified the clockwork that drives a powerful virus nanomotor. Because of the motor's strength--to scale, twice that of an automobile--the new findings could inspire engineers designing sophisticated nanomachines.   view more (2008-12-30)

Research team reports how, when life on Earth became so big
In 3.5 billion years, life on earth went from single microscopic cells to giant sequoias and blue whales. Scientists have now documented quantitatively that the increase in maximum size of organisms was not gradual, but happened in two distinct bursts "tied to the geological evolution of the... view more (2008-12-23)

Small molecule triggers bacterial community
While bacterial cells tend to be rather solitary individuals, they are also known to form intricately structured communities called biofilms.   view more (2008-12-23)

New research lights up chronic bacterial infection inside bone
A new report demonstrates how a sensitive imaging technique gives scientists the upper hand in seeking out bacteria in chronic infections.   view more (2008-12-23)

Unusual microbial ropes grow slowly in cave lake
Deep inside the Frasassi cave system in Italy and more than 1,600 feet below the Earth's surface, divers found filamentous ropes of microbes growing in the cold water, according to a team of Penn State researchers.   view more (2008-12-22)

Blocking the spread of antibiotic resistance in bacteria
It's as simple as A, T, G, C. Northwestern University scientists have exploited the Watson-Crick base pairing of DNA to provide a defensive tool that could be used to fight the spread of antibiotic resistance in bacteria -- one of the world's most pressing public health problems.   view more (2008-12-19)

Sulfurous ping-pong in the urinary tract
Transfer of information is a basic property of biological systems. Common examples include transfer of genetic information or nerve impulses.   view more (2008-12-19)

Tiny magnetic crystals in bacteria are a compass, say Imperial researchers
Scientists have shown that tiny crystals found inside bacteria provide a magnetic compass to help them navigate through sediment to find the best food, in research out today.   view more (2008-12-17)

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)

Just a little squeeze lets proteins assess DNA
To find its target, all a protein needs to do is give quick squeezes as it moves along the DNA strand, suggests new research from The University of Arizona in Tucson.   view more (2008-12-17)

Computation and genomics data drive bacterial research into new golden age
A potent combination of powerful new analysis methods and abundant data from genomics projects is carrying microbiology forward into a new era.   view more (2008-12-09)

Researchers identify cell group key to Lyme disease arthritis
A research team led by the La Jolla Institute for Allergy & Immunology and Albany Medical College has illuminated the important role of natural killer (NK) T cells in Lyme disease, demonstrating that the once little understood white blood cells are central to clearing the bacterial infection... view more (2008-12-04)

Blood tests can help detect presence of necrotizing soft tissue infections
With less than half of patients with necrotizing soft tissue infections displaying the physical signs of these very serious infections, researchers have found two simple blood tests can help physicians diagnose what is commonly known as "flesh-eating bacteria," according to a study in the... view more (2008-12-04)

Vaccine and drug research aimed at ticks and mosquitoes to prevent disease transmission
Most successful vaccines and drugs rely on protecting humans or animals by blocking certain bacteria from growing in their systems. But, a new theory actually hopes to take stopping infectious diseases such as West Nile virus and Malaria to the next level by disabling insects from transmitting... view more (2008-12-03)

Vitamin D found to fight placental infection
In a paper available at the online site of the journal Biology of Reproduction, a team of UCLA researchers reports for the first time that vitamin D induces immune responses in placental tissues by stimulating production of the antimicrobial protein cathelicidin.   view more (2008-12-02)

Scientists Present 'Moving' Theory Behind Bacterial Decision-Making
Biochemists at North Carolina State University have answered a fundamental question of how important bacterial proteins make life-and-death decisions that allow them to function, a finding that could provide a new target for drugs to disrupt bacterial decision-making processes and related diseases.   view more (2008-11-25)

Scientists build 'roach motel' for nasty bugs of the bacterial variety
The vacancy sign is on, but the lowlifes who check in never check out. Scientists at the University of Florida and the University of New Mexico have created tiny microscopic spheres that trap and kill harmful bacteria in a manner the scientists liken to "roach motels" snaring and killing... view more (2008-11-25)

Scripps research scientists identify blood component that turns bacteria virulent
Scientists from the Scripps Research Institute have discovered the key chemical that signals Bacillus anthracis, the bacterium that causes anthrax, to become lethal. This finding opens up new avenues of exploration for the development of treatments for bacterial infections.   view more (2008-11-24)

Scientists discover 21st century plague
Bacteria that can cause serious heart disease in humans are being spread by rat fleas, sparking concern that the infections could become a bigger problem in humans.   view more (2008-11-24)

Stomach ulcer bug causes bad breath
Bacteria that cause stomach ulcers and cancer could also be giving us bad breath, according to research published in the December issue of the Journal of Medical Microbiology.   view more (2008-11-24)

Misreading of damaged DNA may spur tumor formation
The DNA in our cells is constantly under assault from oxygen, the sun's radiation and environmental stresses. Most of the time, our cells can repair the damage before it gets copied into a permanent mutation that could lead to cancer.   view more (2008-11-21)
