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
Health authorities in El Salvador issued a flu epidemic alert, with an average of 14 000 cases a day, exceeding those of dengue fever. Health Minister Maria Isabel Rodriguez told local media that 11 of the 14 departments of the country are the worst affected by respiratory disease.
According ... Read More
Bacteria can elaborate complex patterns of development that are dictated by temporally ordered patterns of gene expression, typically under the control of a master regulatory pathway. For some processes, such as biofilm development, regulators that initiate the process have been identified but s... Read More
To take full advantage of recent increased financial commitments from some governments, international agencies, and philanthropies, accurate and up-to-date mapping of neglected tropical diseases (NTDs) needs to be implemented to help improve the precision of decision-making in NTD control and el...

Every day, millions of microorganisms reach Spain from the Sahara Desert and the Sahel region – by flying. Louis Pasteur demonstrated back in 1861 that germs can move through the air, but it was only recently discovered that bacteria, funguses and viruses can travel thousands of kilometers stuck...
