Many worry that fitness centers attract not just people to exercise, but offer bacteria a place to thrive. But a new University of Florida study of bacteria levels on gym equipment offers a surprising result, about what it didn’t find. Researchers tested dumbbells, benches, and other gym equipme...

Four new Brazilian species in the genus Ophiocordyceps have been published in the online journal PLoS ONE. The fungi, named by Dr. Harry Evans and Dr. David Hughes, belong to a group of "zombifying" fungi that infect ants and then manipulate their behavior, eventually killing the ants after secu...

Univ. of California, Berkeley, chemists have engineered bacteria to churn out a gasoline-like biofuel at about 10 times the rate of competing microbes, a breakthrough that could soon provide an affordable and “green” transportation fuel.
The advance is reported in Nature Chemical Biology by M... Read More
If you're a parent then you're familiar with the 5-second rule.
"The 5-second rule probably should become the zero-second rule," Dr. Roy M. Gulick, chief of the division of infectious diseases at Weill Cornell Medical College, told the Times. "Eating dropped food poses a risk for ingestion of... Read More
Researchers have come closer to understanding how a common fungus "makes its living in the soil," which could lead to its possible "career change" as a therapeutic agent for plant and human health.
Because they are mycoparasites, T. virens attack other, less desirable fungi that can harm root... Read More
Bloodstream infections caused by tubes inserted into major blood vessels of intensive care patients showed a big drop from 2001 to 2009, government researchers said on Tuesday.
But the researchers also reported unacceptably high rates of the same type of infections in other hospital wards and... Read More
A pathway whereby bacteria communicate with each other has been discovered by researchers at the Hebrew University of Jerusalem. The discovery has important implications for efforts to cope with the spread of harmful bacteria in the body.
Bacteria are known to communicate in nature primarily ... Read More
Researchers from the National Institute of Standards and Technology (NIST) and the Weill Cornell Medical College have designed artificial "protocells" that can lure, entrap and inactivate a class of deadly human viruses—think decoys with teeth. The technique offers a new research tool that can b... Read More
If the laboratory is not able to identify group-B streptococci (GBS) by the Lancefield grouping procedure, there are other microbiologic tests that can be used to identify GBS. This picture shows one of these tests. It is called the CAMP test. CAMP is an acronym for the authors of this test (Chr... Read More
US health officials are warning air travelers about possible exposure to measles, after a woman infected with the highly communicable disease traveled in Britain and several US states.
The 27-year-old first traveled from Britain to Washington Dulles International Airport in Virginia, just out... Read More
Good news from the CDC: the number of central-line bloodstream infections in intensive-care patients dropped 58% to an estimated 18,000 in 2009 from 43,000 in 2001.
Why is that important? Because someday you, too, may end up in the ICU with a tube in a chest or neck vein, and you really don’t... Read More
Researchers at The Forsyth Institute have made a significant discovery about the nature of childhood dental disease. The scientific studies led by Anne Tanner, BDS, Ph.D., identified a new pathogen connected to severe early childhood caries (cavities). This bacterium, Scardovia wiggsiae, was pre... Read More
A recent boom in research on the gut microbiota is revealing that these communities are even more integral to human health than previously thought. And now a study published in mBio yesterday draws more links between gut microbes and metabolism. Colonizing the guts of germ-free mice with bacteri... Read More
Writing in the journal Nature Communications, the team have created a microscope which shatters the record for the smallest object the eye can see, beating the diffraction limit of light.
Previously, the standard optical microscope can only see items around one micrometre -- 0.001 millimetres... Read More
This is a debut that I hope will grow into a larger and more useful database: Any contributions are welcome. Read More
Bacterial propulsion systems are intriguing for nanotechnology researchers because nature has already solved most of the problems that they are still struggling with in designing molecular motors and other self-sustained nanoscale actuating systems. Indeed, it has turned out to be very challengi... Read More
New findings by a University of Maryland-led team of scientists indicate that a genetically engineered fungus carrying genes for a human anti-malarial antibody or a scorpion anti-malarial toxin could be a highly effective, specific and environmentally friendly tool for combating malaria, at a ti...

Between 19 January and 17 February 2011, 10 cases of measles (eight laboratory-confirmed and two probable) were reported in Oslo with the majority of cases in a mainly unvaccinated immigrant community. Of these, two cases were identified outside the immigrant community, in Norwegian children. Read More
Half of men in the general population may be infected with human papillomavirus or HPV, the human wart virus that causes cervical and other cancers, strengthening the case for vaccinating boys against HPV, U.S. researchers said on Monday.
U.S. vaccine advisers have been weighing whether boys ... Read More
