The microscopic plants that form the foundation of the ocean's food web are declining, reports a study published July 29 in Nature.
The tiny organisms, known as phytoplankton, also gobble up carbon dioxide to produce half the world's oxygen output—equaling that of trees and plants on land.

Take mice from freezer. Thaw (but not in the microwave, please). Feed to pet snakes. And do not forget to wash your hands.
That is the message from public health officials in the wake of salmonella outbreaks that have sickened more than 400 people, many of them snake owners or their children,... Read More

The new strain, ST131, was a major cause of serious antimicrobial-resistant E. coli infections in the United States in 2007, researchers found. This strain has been reported in multiple countries and encountered all over the United States. In the study, researchers analyzed resistant E. coli i... Read More
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
