Scientists are learning how our immune system senses and tracks down infection in the body by responding to chemical "scents" emitted by bacteria. Studying how immune cells manipulate their movement in response to external signals could shed light not only on how our immune system functions but ... Read More
Researchers are showing renewed interest in learning how phages interact with bacterial hosts, adapting to and overcoming their defenses. The abundance of phages and their importance to evolution and to ecology provide an incentive to study them. The golden era for studying phages stretched from... Read More
Enjoy this scientific spring scavenger hunt and find the answers to these 10 questions on the history of microbiology. The birth of microbiology revolved around many key discoveries beginning around the mid to late 1600’s. These discoveries were at the cutting edge of science at the time and th... Read More
PigContinuing activity of pandemic H1N1 influenza in the Southeast, particularly in Georgia, is raising fears of a third wave of swine flu, federal officials said Monday. They urged people to continue getting vaccinated as a preventive measure in case a new outbreak occurs.
Although swine flu... Read More
Halliburton Co. and Schlumberger Ltd., trying to forestall a regulatory crackdown that would cut natural-gas drilling, are developing ways to eliminate the need for chemicals that may taint water supplies near wells.
At risk is hydraulic fracturing, or fracking, a process that unlocked gas de... Read More
Amy Maxmen reports over at Nature News that a team of European researchers has decoded the genome of the Périgord black truffle. Francis Martin, at the French National Institute for Agricultural Research in Nancy, and his colleagues have found that "within its nucleotides reside secrets to the f... Read More
The microbial ecosystem inside the carnivorous pitcher plant is vastly more diverse than previously thought according to research published in the March 2010 issue of the journal Applied and Environmental Microbiology.
Researchers from Louisiana State University used genomic fingerprinting t... Read More
it is not a nice way to die. As the virus spreads through your lungs, your immune system goes into overdrive. Your lungs become leaky and fill with fluid. Your lips and nails, then your skin, turn blue as you struggle to get enough oxygen. Basically, you drown.
Flu can kill in other ways, too... Read More
The effectiveness of ordinary surgical masks as opposed to respirators in protecting health care workers against the 2009 H1N1 influenza virus has been the subject of debate. An observational study published in the April 1, 2010 issue of Clinical Infectious Diseases, available online, suggests t... Read More
Use of the rotavirus vaccine Rotarix in the US has been temporarily suspended because the vaccine was found to be contaminated with porcine circovirus 1 DNA. The discovery was made in the laboratory of Dr. Eric Delwart, who has provided insight into what was found in Rotarix, and why he was anal... Read More
Most of life on Earth is a mystery to us. The bulk of biomass on the planet is made up of microbes. By some estimates, there may be 150 million species of bacteria, but scientists have only formally named a few thousand of them. One of the big causes of this ignorance is that scientists don’t kn...

Life not only survives but thrives in Australian lakes where conditions may be as harsh as those on ancient Mars, a new DNA analysis suggests.
Minerals on Mars studied by the NASA rovers suggest water once flowed on the planet's surface, but was very salty and acidic, raising doubts about whe... Read More
Sixty-three South Africans are infected, according to the latest figures released by the Department of Health yesterday. This number went up from 52 on Thursday, to 60 on Friday and then to 63 yesterday. Two people in the Free State have also died in recent weeks. Rift Valley Fever causes diseas... Read More
The factors instrumental in triggering latent tuberculosis (TB) infection to progress into active disease have long remained elusive to researchers. New insight into the mystery is provided by Professor David Russell, speaking at the Society for General Microbiology's spring meeting in Edinburgh... Read More
Pathogenic bacteria in the gut recognise their surroundings by detecting hormone signals from the host, which can prompt them to express lethal toxins. Intercepting these hormonal messages could be a better way to treat serious food-borne infections where antibiotics do more harm than good, expl... Read More
It's not uncommon to hear of norovirus outbreaks sickening cruise customers. Now, a recent outbreak of the virus could be traced back to an airline flight in Ohio. The Columbus Dispatch writes "norovirus is to blame for an outbreak of gastrointestinal illness that sickened at least 18 student-at... Read More
The US Food and Drug Administration has issued an alert regarding at least 12 confirmed illnesses in Michigan that are associated with the bacteria Campylobacter in raw, unpasteurized milk.
The FDA is collaborating with the Michigan Department of Community Health (MDCH) among other state agen... Read More
Television shows remind us of the traces we can leave behind, clues that could link a criminal to the scene of a crime: a careless fingerprint, a spatter of blood, a stray hair. A recent study offers a new way to identify people that might sound far-fetched even to a scriptwriter: the bacteria o... Read More
Antibiotics have been used since the 1940s to cure tuberculosis. But the bacterium that causes the disease, Mycobacterium tuberculosis, keeps evolving to dodge the drugs that are thrown at it, and existing treatments are becoming less effective. Now, Howard Hughes Medicial Institute (HHMI) scien... Read More
