How about swallowing a batch of pig whipworm eggs, or deliberately infecting oneself with the fecal-dwelling hookworm? Yucky as these options sound, mountin... Read More
Blue-green algae, or cyanobacteria, grow in vast numbers in the sunlit surface waters of the oceans, the photic zone. They use sunlight to 'fix' carbon by converting carbon dioxide into sugars and other organic compounds through photosynthesis.
Cyanobacteria belong to the 'picophytoplankton',... Read More
Fetching our newspaper & slippers, guarding the homestead from intruders, alerting us that Timmy has fallen into the old well - and now this. if we could determine which of our cave-person ancestors had the brilliant notion to domesticate these critters, that knuckle-dragger deserves an award f...

A decade after the world’s original deadline for eradicating polio, the most tenacious bastions of the crippling virus — Nigeria and India — have recently shown remarkable progress in halting its spread, giving even some of the antipolio campaign’s severest doubters hope that it may yet largel...

The safety of antimicrobial soaps and toothpastes is under review following concerns that they could interfere with hormones in the body.
Last week, the US Food and Drug Administration said it will re-evaluate the safety of triclosan, which is added to plastics, soaps and toothpastes to kill ... Read More
Researchers testing bushmeat smuggled into the U.S. have found strains of a virus in the same family as HIV, according to preliminary findings to be released Wednesday.
For years, authorities have tried to crack down on the smuggling of meat from certain animals, such as bats, monkeys and rod... Read More
Biochemist Daniel Schabacker of DOE's Argonne National Laboratory could be considered a Sherlock Holmes of bioterrorism. Although he doesn’t carry around a pipe and magnifying glass as he attempts to nab the culprit, he has a far more powerful deductive tool: the biochip.
The biochip offers Sch... Read More

The heel-stick test commonly used for screening newborns for a variety of genetic disorders is not a good way to test for cytomegalovirus infections, the most common nongenetic cause of hearing loss, researchers reported Tuesday. About 20,000 to 30,000 infants in the U.S. are born with cytomegal... Read More
Fluorescence-tagged Escherichia coli cells can be made to "blink" in unison by means of a constructed network of genes and proteins that coordinates oscillations within the growing cell population, according to Jeff Hasty and colleagues from the University of California, San Diego (UCSD) in La J...

Bad company: Cryptococcus neoformans is responsible for an estimated 1 million cases of cryptococcal disease every year, predominantly meningoencephalitis. These cases are often fatal. So, what’s worse than an infection with one kind of Cryptococcus? A new paper selected for the inaugural iss... Read More
A new online global map could soon help scientists better track and predict outbreaks of infectious diseases like H1N1 much the same way meteorologists can study and forecast the weather. The "Supramap" application illustrates the spread of pathogens and key mutations across time, space and vari... Read More
Indiana University has received more than $1.8 million from the National Institutes of Health to collaborate on a $12.2 million, seven-university project designed to network researchers around the country.
While the proposed new networking system will contain authentication mechanisms to prot... Read More
Hydrogen gas is today used primarily for manufacturing chemicals, but a bright future is predicted for it as a vehicle fuel in combination with fuel cells. In order to produce hydrogen gas in a way that is climate neutral, bacteria are added to forestry or household waste, using a method similar... Read More
Deep sequencing – which identified a viral contaminant of the rotavirus vaccine Rotarix - could have revealed the presence of simian virus 40 (SV40) in the poliovirus vaccine, had the technique been available in the 1950s. Exposure of over 100 million Americans to SV40, and many more worldwide, ... Read More
To feed an exploding global population, scientists have called for a doubling of food production over the next 40 years. Genetic manipulation might seem the best way to quickly boost characteristics essential to plant growth and crop yields. New findings from different laboratories, however, sug... Read More

The human mouth is home to an estimated 800 to 1,000 different kinds of bacteria. The warm and moist environment, along with hard tooth surfaces and soft tissues, prove to be optimal factors in boosting germ growth. Many of these bacteria are harmful and can form a film on teeth called "dental p... Read More
