Ever awkwardly tried to open a door with your sleeve as a barrier against that dirty doorknob? Or done the tricky dance of attempting to flush the toilet with your foot to avoid that germ-laden handle?
Despite your dances to avoid seemingly obvious germ hang-outs, the dirtiest surface in your... Read More
In recent years, efforts to combat drug-resistant bacteria have focused on the immediate goal of reducing rates of hospital-acquired infections. But now global health officials face an approaching crisis: the number of different antibiotics available to treat such infections when they do occur i... Read More
Bacterial lung infections were common among 77 people who died because of the 2009 H1N1 flu, a finding similar to past pandemics, the CDC said.
In a subset of the 600 U.S. deaths associated with the current pandemic, 29% had a bacterial coinfection, the agency said in a early release from the... Read More
Engineered E. coli bacteria can now trace the outline of an image on an agar plate in a feat that shows how manipulating small organisms could lead to synthetic biological devices useful to technology and medicine.
"It looks like a pen came in and traced the outline of the image," said Jeff T... Read More
Scientists are reporting discovery of a much sought after crack in the armor of a common microbe that infects the stomachs of one-sixth of the world’s population, causing stomach ulcers and other diseases. They identified a group of substances that block a key chemical pathway that the bacteria ... Read More
A student produced documentary, "Roots to Stem: Spelman Women in Science, profiles the careers of African American female scientists.
Even though there is an increasing rate of African American women in science undergraduate sciences classes, the number of these women actually entering into ... Read More
Air travel doesn't pose extra risks for individuals, infectious disease experts say, but it does spread diseases between populations.
Passengers may worry viruses will spread around planes in recirculated air, but that isn't a concern thanks to the high efficiency particulate filters that cat... Read More
Thousands of bacteria lurk in college dormitories, but students are not following proper hygiene routines to help protect themselves from serious illness, according to a study released today from the Simmons College Center for Hygiene and Health in Home and Community, sponsored by an educational...

Since its discovery in January 2007 the lethal fungal infection known as white-nose syndrome (WNS) has killed at many as 1.5 million bats in the U.S. Northeast. Now, as temperatures start to drop this autumn into the range where WNS operates at its optimal killing capacity, the U.S. Fish & Wildl... Read More
A trip to the dentist could perhaps have saved many a mighty Tyrannosaurus rex.
Holes found in the jawbones of 10 T. Rex – including "Sue" at the Field Museum in Chicago – may not be battle scars from fighting with rivals as previously thought. The holes are more consistent with parasitic inf... Read More
A University of Toronto-led team has uncovered the evolutionary ancestry of the prion gene, which may reveal new understandings of how the prion protein causes diseases such as bovine spongiform encephalopathy (BSE), also known as "mad cow disease."
Diseased prion proteins are responsible for... Read More
Saudi Arabia has announced that everyone arriving for the annual pilgrimage to Mecca in November will have to swallow a dose of oral polio vaccine under the eyes of health officials.
The kingdom has become more and more aggressive in its fight against polio, which has hovered on the brink of ... Read More
Pregnant women are deluged with advice about things to avoid: caffeine, paint, soft cheese, sushi. Even when evidence of possible harm is weak or purely theoretical, the overriding caveat is, “Don’t take it, don’t use it, don’t do it.”
In a few contexts, the admonition is warranted; in most, ... Read More
A team of researchers at MIT are engineering a strain of bacteria, which is similar to the type that causes tuberculosis, to produce biofuel.
The researchers say that the bacteria are useful because they are hungry for a number of sugars and toxic compounds and produce lipids that can be conv... Read More
When the label tells you the food you are buying “contains probiotics,” are you getting health benefits or just marketing hype? Perhaps a bit of both.
Probiotics are live micro-organisms that work by restoring the balance of intestinal bacteria and raising resistance to harmful germs. Taken i... Read More
They lurk on the kitchen sponge, your computer keyboard and the dirty laundry. Flush the toilet and they become airborne. Strangers leave them behind on airplanes, gas pumps, shopping carts, coffeeshop counters and elevator buttons. Your desktop, office microwave handles, and the exercise bike a... Read More
Coral reefs where lots of different kinds of fish swim are healthier than overfished ones, scientists have shown.
Researchers showed a reduced incidence of coral disease in areas of the Philippines where fishing is banned, compared with neighbouring areas.
They conclude that some types of ... Read More
Exposure to light and possibly photosynthesis itself could be helping disease-causing bacteria to be internalized by lettuce leaves, making them impervious to washing, according to research published in the October issue of the journal Applied and Environmental Microbiology.
Salmonella enteri... Read More
