When champion surfer Andy Irons was found dead in a Dallas hotel room this week, family members said they suspected he had dengue fever — a virus transmitted by mosquitoes in tropical countries.
Irons had been in Puerto Rico to compete in a surfing contest, but bailed out early because he was... Read More
There's still no vaccine for HIV, but researchers have made inroads in discovering new clues to why a minority of infected people can carry the virus without symptoms.
Only about one in 300 people infected appear to have an immune system that can naturally suppress the virus's replication, an... Read More
A team from The Scripps Research Institute has revealed the first-ever pictures of the formation of cells' "protein factories." In addition to being a major technical feat on its own, the work could open new pathways for development of antibiotics and treatments for diseases tied to errors in ri... Read More
Some bacteria react to the cold by subtly changing the chemistry of their outer wall so that it remains pliable as temperatures drop. Scientists identified a key protein in this response mechanism a few years ago, but the question of how bacteria sense cold in the first place remained a mystery.... Read More
A way to eliminate a debilitating side effect associated with one of the main chemotherapy drugs used for treating colon cancer has been found by a team of scientists.
The strategy used in their preclinical research-inhibiting an enzyme in bacteria of the digestive tract-could allow patients ... Read More
Worried about an impending public health crisis, government officials are considering offering financial incentives to the pharmaceutical industry, like tax breaks and patent extensions, to spur the development of vitally needed antibiotics.
While the proposals are still nascent, they have t... Read More
Most mutations in the genes of the Salmonella bacterium have a surprisingly small negative impact on bacterial fitness. And this is the case regardless whether they lead to changes in the bacterial proteins or not. This is shown by Uppsala University scientists in an article being published toda... Read More
Costco Wholesale Corp. and federal health officials are warning consumers that a cheese sold recently at Costco stores in Arizona and four other states has been preliminarily linked to an E. coli outbreak that has sickened 25 people.
The Bravo Farms Dutch Style Raw Milk Gouda Cheese was offer... Read More
The Energy Biosciences Institute at the University of California at Berkeley earlier this week released an analysis of the state of the algae biofuels industry and projected some of its future needs.
Its overall conclusion is that a significant amount of research and development is needed, ev... Read More
The scientific community has lost one of the early pioneers in
brucellosis research: Dr Margaret E Meyer.
Dr Meyer died on Fri 8 Oct 2010 after a long struggle with pulmonary
disease. She leaves a vast legacy of contributions to the veterinary
world. She was professor at UC [University ... Read More
A team of Université Laval and Danisco researchers has just unlocked the secret of bacteria's immune system. The details of the discovery, which may eventually make it possible to prevent certain bacteria from developing resistance to antibiotics, are presented in the November 4 issue of the sci...

The rhizosphere is the narrow region of soil that is directly influenced by root secretions and associated soil microorganisms. A new study by scientists at Purdue University found that E. coli bacteria thrive in this region, critical to plant growth.
Scientists conducted the study by adding... Read More
It has long been thought disease-causing viruses can take shelter from your body's defenses, the immune system, by hiding inside cells. But a new study from British researchers found this is not the case.
Antibodies, which are proteins in the immune system, can latch on to some viruses and fo... Read More
For decades, they lived a mystery: Why were they able to survive with the AIDS virus, free of symptoms and the need for potent drugs, while so many others with the same germ turned deathly ill?
Their innate ability to keep HIV infections in check intrigued researchers, who suspected these peo... Read More
There is a great deal of interest in the impact of lactic acid bacteria on our health. Now a new study from the Faculty of Health and Society, Malmö University, in Sweden, shows that the occurrence of Lactobacillus reuteri in the body promotes health.
Humans have used lactic acid bacteria for... Read More
Over-probing airport security scans? Nope. Soft porn from the 22nd Century? Definitely not. These beautiful images of the human body are part of a new exhibition at the Royal Institution. Each was taken using the light emitted by the bioluminescent bacteria Photobacterium phosphorem. Artist Anne... Read More
Mutually-beneficial cooperation is a high ideal, but for bacteria and archaea, working together isn’t always a good solution. Now a team at Pennsylvania State University has worked out a system that could work better than inter-domain cooperation: by putting genes from a bacterium into an archa... Read More
Not long ago, microbiologists at the University of Texas Health Science Center at San Antonio solved a longstanding medical mystery: A common pathogen, Mycoplasma pneumoniae, was known to be involved in disease pathways throughout the body, but no one knew how it worked. Then the microbiologists... Read More
When a team of European researchers sought to discover how a class of antiviral drugs worked, they looked in an unlikely place: the sugar dish. A new research report appearing in the Journal of Leukocyte Biology suggests that a purified and modified form of a simple sugar chain may stop fast-act... Read More
