Prior Exposure to Seasonal Influenza May Explain the Mildness of the 2009 H1N1 Pandemic
Hong Kong researchers suggest a new theory for why swine flu infections turned out to be so mild. Prior exposure to seasonal influenza A, either infection or vaccination, may induce a cross-reactive immune... Read More
Are you a little OCD when it comes to germs? Do you feel like you need to wash your hands after you use your iPad? Did that report about the iPad screens in Apple Stores being hotbeds for assorted fungi and bacteria make you want to take a long, hot shower?
If you answered yes to any of these... Read More
Current technology used by BP is proving hopelessly inadequate in curbing the tide of oil gushing from beneath the Gulf of Mexico. Now, novel technologies that remain untested at such an incomprehensible scale will be needed in anticipation of years of remediation to resuscitate a dying ecosyste... Read More
How's this for preventative medicine?: Ingesting bacteria may help to prevent infections.
Researchers at Creighton University School of Medicine in Omaha, Neb., recently demonstrated that regular doses of probiotic bacteria given to hospital patients on mechanical ventilators resulted in fewe... Read More
You know saving the rainforest is good for biodiversity. But it may also be a boon to human health. That's because less clear-cutting may mean less malaria, according to a paper out this week in the journal Emerging Infectious Diseases. [Sarah Olson et al., http://bit.ly/b6iFgT]

Scientists in Munich report evidence that high concentrations of the molecular "chaperone" proteins GroEL and GroES -- intracellular machines that can stabilize folding proteins under stress -- play a critical role in increasing the maximum temperature at which E. coli bacteria can grow. Massive... Read More
It's a tragedy of war that innocent bystanders often get caught in the crossfire. But now scientists at the University of Pennsylvania and the University of Oxford have shown how a battle for survival at a microscopic level could leave humans as the unlikely victims.
In work funded by the US ... Read More
Dear Dr. Dickson Despommier and Dr. Vincent Racaniello
I am a microbiologist. I studied in Colombia and after finishing my bachelor's I moved to New York city in 2007. All my life I have been fascinated about microorganisms. Some weeks ago I found an i... Read More

There is too little genetic surveillance of last year’s human pandemic flu, which has gone on to infect pigs in China and is readily mixing with other flus there, according to a study released Thursday by researchers in Hong Kong.
No dangerous new strain has emerged, said several experts who ... Read More
Wild potato germplasm that offers resistance to some major potato diseases has been identified by Agricultural Research Service (ARS) scientists.
Geneticists Dennis Halterman and Shelley Jansky pinpointed the resistant wild potato species in studies at the ARS Vegetable Crops Research Unit in... Read More
A single species of bacteria that lives in the gut is able to trigger a cascade of immune responses that can ultimately result in the development of arthritis.
Our gut, like that of most mammals, is filled with thousands of species of bacteria, many of which are helpful and aid in the develop... Read More
A new strain of swine flu shows that the pandemic version has jumped from humans back to pigs, where it’s evolving in new and unpredictable ways.
The new strain, identified in a Hong Kong slaughterhouse, isn’t especially virulent. But the findings emphasize the need for continued vigilance. S... Read More
Researchers have found antibiotic-resistant bacteria in seven species of sharks and redfish captured in waters off Belize, Florida, Louisiana and Massachusetts. Most of these wild, free-swimming fish harbored several drug-resistant bacterial strains.
The study, published in the Journal of Zoo... Read More
Some bacteria destroy oil. Might those bacteria lead oil companies to change their methods of harvesting the energy of the oil while at the same time reducing the carbon dioxide that burning oil and gasoline discharges into the atmosphere? Steve Larter thinks that may be possible.

An experimental vaccine developed to prevent outbreaks of Marburg hemorrhagic fever continues to show promise in monkeys as an emergency treatment for accidental exposures to the virus that causes the disease. There is no licensed treatment for Marburg infection, which has a high fatality rate.

Intermittent preventive treatment in infants (IPTi) has been shown to decrease clinical malaria by approximately 30% in the first year of life and is a promising malaria control strategy for Sub-Saharan Africa which can be delivered alongside the Expanded Programme on Immunisation... Read More
For a culture raised on images of Dr. Frankenstein cackling "It's alive!" as his monster lurched around the lab, the recent announcement by the J. Craig Venter Institute claiming they had created synthetic life received surprisingly mixed reviews.
The scientific consensus is that the institu... Read More
