Powerful mold-inhibiting bacteria patented
Bacteria that produce lactic acid have been used for thousands of years to preserve food. Some lactic acid bacteria also produce several other mold-inhibiting substances and are therefore of special interest to agriculture and the foodstuffs industry. This is demonstrated in a dissertation by Jörgen Sjögren from the Swedish University of... view more... (2005-04-08)
Fine-tuning lasers to destroy blood-borne diseases like AIDS
Physicists in Arizona State University have designed a revolutionary laser technique which can destroy viruses and bacteria such as AIDS without damaging human cells and may also help reduce the spread of hospital infections such as MRSA. view more (2007-11-01)
Insignia -- A new way to identify viruses and bacteria
Now that the genome sequences of hundreds of bacteria and viruses are known, we can design tests that will rapidly detect the presence of these species based solely on their DNA. view more (2007-05-18)
Natural antibiotics yield secrets to atom-level imaging technique
Frog skin and human lungs hold secrets to developing new antibiotics, and a technique called solid-state NMR spectroscopy is a key to unlocking those secrets. view more (2007-03-05)
Scientists identify specific enzymes that make meningitis hard to fight
Two enzymes in meningitis bacteria which prevent the body from successfully fighting off the disease, and make the infection extremely virulent, have been identified in new research published today. view more (2007-02-23)
New approach could lower antibiotic requirements by 50 times
Antibiotic doses could be reduced by up to 50 times using a new approach based on bacteriophages. view more (2007-01-29)
Northwestern exposing most deadly infectious diseases in 3-D
A scientist slides on a pair of plastic 3-D glasses and an unearthly blue multi-armed creature -- an image right out of a sci-fi horror flick -- seems to leap out of the computer screen into the laboratory. view more (2007-11-01)
UGA study reveals a new way of looking at vaccine development
University of Georgia researchers have given vaccine developers a new tool that could lead to the development of designer vaccines that protect against a wider range of diseases or work against diseases that are currently hard to prevent. view more (2006-05-23)
Rutgers-Newark researcher discovers new motor protein mechanism linked to heart disease and strokes
Cardiomyopathy is an insidious disease which often strikes without warning and can lead to heart failure and eventual death. Although the disease can be traced to conditions such as high blood pressure, heart valve or arterial diseases and congenital heart defects, it is also caused by viral infections in the bloodstream. view more (2006-07-24)
New research may reduce global need for nitrogen fertilizers
Research published tomorrow (June 29) in the journal Nature reveals how scientists at the John Innes Centre (JIC), Norwich and Washington State University, USA have managed to trigger nodulation in legumes, a key element of the nitrogen fixing process, without the bacteria normally necessary. view more (2006-06-29)
New petroleum-degrading bacteria found at Rancho La Brea Tar Pits in Los Angeles
Environmental scientists at UC Riverside have discovered that the Rancho La Brea tar pits in downtown Los Angeles, Calif., house hundreds of new species of bacteria with unusual properties, allowing the bacteria to survive and grow in heavy oil and natural asphalt. view more (2007-05-11)
Problem: Implant Infection. Solution: Nanotech Surfaces
Orthopaedic implants help millions of Americans stay active. But these medical devices are prone to infection, forcing patients back to surgery for repair or replacement. Now, for the first time, a team of engineers has shown that zinc or titanium oxide nanosurfaces can reduce the presence of bacteria, a technique that can be applied to implants... view more...

Genetically altered cells may help artificial skin fight infection
Cincinnati burn researchers have created genetically modified skin cells that, when added to cultured skin substitutes, may help fight off potentially lethal infections in patients with severe burns. view more (2007-01-09)
Antibiotic Resistance and Gene Transfer
The way antibiotic resistance spreads and possible problems from genes transferring have been identified by researchers from the Rowett Research Institute in Aberdeen, in new evidence about the way genes pass from one bacterium to another. The research is presented today, Monday 7 April 2003, by Dr Karen Scott at the Society for General... view more... (2003-04-02)
'Good' bacteria could save patients from infection infection by deadlier ones
Can it be that the stress on the use of antiseptics and antibiotics in hospitals is actually putting patients at a greater risk of suffering fatal bacterial infection? view more (2005-11-03)
Measuring the health of the sea
Last summer Donostia City Council in the Basque Country installed a special buoy in the city's Concha Bay for the first time. The apparatus carried out analyses of the water quality in order to verify its suitability for bathing. This buoy was anchored at the bottom of the sea, halfway between the Santa Clara islet and the Concha and Ondarreta... view more... (2003-07-28)
Prehistoric origins of stomach ulcers uncovered
An international team of scientists has discovered that the ubiquitous bacteria that causes most painful stomach ulcers has been present in the human digestive system since modern man migrated from Africa over 60,000 years ago. view more (2007-02-08)
MRSA in the community: A new threat to children's health?
Although hospital superbugs like MRSA - methicillin resistant Staphylococcus aureus - are now a widespread and recognised problem, new MRSA strains that have emerged and are spreading amongst the wider public in the USA may pose a bigger threat. view more (2007-11-28)
Scientists describe new way to peer inside bacteria
As part of the search for better ways to track and clean up soil contaminants, scientists at the U.S. Department of Energy's Brookhaven National Laboratory and Stony Brook University have developed a new way to "image" the internal chemistry of bacteria. view more (2005-08-30)
Researchers identify antibiotic protein that defends the intestine against microbial invaders
Researchers at UT Southwestern Medical Center have identified a protein that is made in the intestinal lining and targets microbial invaders, offering novel insights into how the intestine fends off pathogens and maintains friendly relations with symbiotic microbes. view more (2006-08-25)
