Splashing around in a swimming pool on a hot summer day may not be as safe as you think. A recent University of Illinois study links the application of disinfectants in recreational pools to previously published adverse health outcomes such as asthma and bladder cancer.
Each year, 339 million... Read More
Viruses do not make good fossils. But advances in genomic technology have allowed scientists to peer into the genetic material of viruses and their hosts to search for clues about their shared evolutionary history.
Genetic code from retroviruses has been found to compose some 8 percent of the... Read More
The Food and Drug Administration said Friday that it had approved vaccines for the next flu season, expected to start in the fall, and health officials are recommending vaccination for everyone 6 months old and older.
Last year’s notorious virus, the pandemic A(H1N1) swine flu, has now become... Read More
The emergence of the 2009 pandemic influenza A(H1N1) virus in North America and its subsequent global spread highlights the public health need for early warning of infectious disease outbreaks. Event-based biosurveillance, based on local- and regional-level Internet media reports, is one approac... Read More

In addition to working as a scientist, and well before his discovery of antibiotics, Alexander Fleming painted. He was a member of the Chelsea Arts Club, where he created amateurish watercolors. Less well known is that he also painted in another medium, living organisms. Fleming painted ballerin... Read More
True story. Bill across the street from me keeps honeybee hives. Recently, Bill's next-door neighbour saw a swarm in her back yard. Frightened, she ran indoors. (Once a hive gets to a certain size, some bees will depart with a new queen.) As the swarm weaved along the street from tree to tree, a... Read More
Escherichia coli bacteria have been genetically engineered to produce artificial spider dragline silk, which is five times stronger than steel and has multiple potential applications.
Sang Yup Lee at the Korea Advanced Institute of Science and Technology (KAIST) led the research to find a via... Read More
Swimming in the rivers that feed the Chesapeake Bay after a hard rain could be as hazardous to your health as hopping into an unflushed toilet.
That was a key finding of a water quality experiment conducted this month by reporters at the University of Maryland working for News21, a national c... Read More
Researchers have described a previously unknown biological mechanism in cells that prevents them from consuming themselves for fuel.
The mechanism involves the fuel used by cells under normal conditions and relies on an ongoing transfer of calcium between two cell components via an ion channe... Read More
Scientists have uncovered the mechanism behind Salmonella's virulence and its susceptibility to antibiotics.
Although the mechanism had not been recognized before, the scientists were intrigued to find evidence of a similar mechanism in all five kingdoms of life - animals, plants, fungi, pro... Read More
On Wednesday the U.S. Department of Agriculture's Food Safety and Inspection Service announced that the agency is now accepting nominations for new members for the National Advisory Committee on Microbiological Criteria for Foods.
FSIS is seeking nominations for two-year terms from individual... Read More
Some trees growing in nutrient-poor forest soil may get what they need by cultivating specific root microbes to create compounds they require. These microbes are exceptionally efficient at turning inorganic minerals into nutrients that the trees can use. Researchers from France report their find... Read More
A virus known to cause cervical cancer in women is increasingly being identified in head and neck cancers, leading to suspicion that the route of infection may be oral sex.
Human papillomavirus, or HPV, is often associated with genital warts and cervical cancer, but the virus can cause numero... Read More
The ebola virus is one of the nastiest pathogens known to man. It corrodes blood vessels and stops clotting, leaving most of its human victims bleeding to death through their pores. And guinea pigs — along with opossums, wallabies and insect-eating bats — have it in their genes.
A genomic hun... Read More

I wouldn't recommend anyone wear the same pair of underwear for a full month without washing them; the results would not be pretty. But a new type of nanotechnology-infused underwear that are quick-drying and odor-absorbing? Well, if they're good enough for astronauts, they should be good enough... Read More
A group of investigators at the Rensselaer Polytechnic Institute (RPI) recently managed a significant breakthrough in their studies of the dangerous bacteria Vibrio cholerae. The bacterium is the agent that causes the terrible infectious disease known as cholera, but the team believes that this ... Read More
Often causing no symptoms in carriers of the disease, worldwide tuberculosis (TB) infects eight to ten million people every year, kills two million, and it is highly contagious as it is spread through coughing and sneezing. "It's a global health disaster waiting to happen, even here in Canada, b... Read More
Public immunization efforts may be much more sensitive than previously realized to small changes in the perceived costs or risks of vaccination, scientists at Harvard University report this week. In some cases, the spread of vaccine avoidance via social networks can make the difference between a... Read More
