Medical Diagnostics: A library of peptides on the surfaces of bacteria can capture new antibodies associated with celiac disease.
Celiac disease, an autoimmune disorder, is notoriously difficult to diagnose, particularly in its early stages. Now, researchers have developed a strategy to captu... Read More
Scientists at Argonne are on a mission to sort out the trillions of good and bad microbes carried around by the human body.
Biologist Daniel Smith crouched in an empty patient room at the new University of Chicago hospital and dragged a white cotton swab across the gleaming tile.
Smith s... Read More
Poor Larry isn't looking too good. He's pale and clammy and he's been projectile vomiting over and over again while his carers just stand by and watch.
Yet their lack of concern for Larry is made up for by their intense interest in how far splashes of his vomit can fly, and how effectively th... Read More
Questionnaire suggests researchers not as safe as they feel. Scientists may have a false sense of security about the safety of their laboratories, according to early results from the first international survey of researchers’ workplace attitudes and practices.
Some 86% of the roughly 2,400 sc... Read More
Carl Woese, a biophysicist and evolutionary microbiologist whose discovery 35 years ago of a “third domain” of life in the vast realm of micro-organisms altered scientific understanding of evolution, died on Sunday at his home in Urbana, Ill. He was 84.
His death was announced by the Universi... Read More
On a sparkling New England afternoon, as hawks coasted overhead and yellow leaves drifted to the ground, Anne Pringle stood before a large granite obelisk that marked the graves of a family called French.
In this bucolic cemetery, steps from the headquarters of Harvard’s research forest, she ... Read More
Infection control experts at The Johns Hopkins Hospital have found that a combination of robot-like devices that disperse a bleaching agent into the air and then detoxify the disinfecting chemical are highly effective at killing and preventing the spread of multiple-drug-resistant bacteria, or s...

The University of Michigan Center for the History of Medicine launched a new website in October called "The American Influenza Epidemic of 1918-1919: A Digital Encyclopedia."
As the name suggests, the site is a chronicle of the American experience during the influenza pandemic of 1918-1919 --... Read More
In 2011, an outbreak of Listeria monocytogenes in cantaloupe led to almost 150 illnesses and 30 deaths. With a spate of recent outbreaks of such foodborne pathogens as Salmonella , Shiga toxin-producing E. coli and L. monocytogenes , the ability to predict where and how these deadly microbes ent...

I comment a bit, as an educator, about the loss of Carl Woese. Not only the importance of his discoveries, but how he went about his work, remains of great value. Read More
The “quantified self” movement might need a new name. Enthusiasts are now tracking not just themselves but the trillions of bacteria that live in and on their bodies.
Self-trackers use smartphone apps and gadgets to keep tabs on how much they exercise and what they eat—as well as their blood... Read More
Different microbes may create variations in otherwise identical wine grapes in the same vineyard and affect the wine's flavor, South African researchers say.
Mathabatha Setati and colleagues from Stellenbosch University said various microbes could contribute to flavor fluctuations in samples ... Read More
Hong Kong has earned another accolade, with a new bacteria named after the city.
Streptococcus hongkongensis was discovered when a worker at one of the city's fish stalls cut his thumb on a fish fin.
The 44-year-old man did not seek treatment for his wound, until after a month when the swe... Read More
Rare brain tumors found in raccoons in Northern California and Oregon may be linked to a new virus, according to a new study.
Researchers, led by scientists from the University of California, Davis, said their findings could shed light on how viruses cause cancer in both animals and humans.

If we assume that life got started during the warmer, wetter conditions of Mars' past, could it still be hanging on somewhere under its frigid, sparse atmosphere? Without a careful examination of hundreds of potential habitats around the red planet, that question is probably impossible to defini... Read More
For decades, scientists have known that deforestation is one of the greatest threats to the biodiversity of the Amazon rainforest, which has the highest number of plant and animal species of any region its size on the planet. Now, scientists have found out that deforestation is a threat to the d... Read More
Research published today in the journal Proceedings of the National Academy of Sciences shows that some bacterial cells carry a molecular 'suicide complex' to kill themselves in the event of lethal infection by viral parasites. Such 'altruistic suicide' prevents or limits viral replication and p... Read More
A collaboration between researchers at the School of Biochemistry and Immunology and the Department of Microbiology at Trinity College Dublin has identified a mechanism by which the bacterium Staphylococcus aureus (S. aureus) colonizes our nasal passages. The study, published today in the Open A... Read More
