Though proponents of unpasteurized milk tout its health benefits, including boosting immunity, scientific evidence remains shaky. More and more consumers are forgoing standard milk in favor of "raw" milk, milk that's unpasteurized and unhomogenized, essentially straight from the udder of the cow... Read More
When I worked at a vet hospital people asked me all the time whether dog's mouths were cleaner than humans. I always told them it was an old wive's tale & wondered about their personal hygiene. Turns out I was wrong! Read More
Misunderstandings about proper use of antibiotics have the potential to spread widely through social networks such as Twitter, according to a report in the April issue of AJIC: American Journal of Infection Control.
Researchers from Columbia University and MixedInk (New York, NY) studied the ... Read More
Bile secretions in the small intestine send signals to disease-causing gut bacteria allowing them to change their behaviour to maximise their chances of surviving, says Dr Steve Hamner, presenting his work at the Society for General Microbiology's spring meeting in Edinburgh. The findings could ... Read More
A federal judge on Monday struck down patents on two genes linked to breast and ovarian cancer. The decision, if upheld, could throw into doubt the patents covering thousands of human genes and reshape the law of intellectual property.

When Rachel Sarah took her daughter in for her first dental checkup a few years ago, she got a surprise. Not only did her 24-month-old have two cavities in her baby teeth, the pediatric dentist suggested she might have “caught” them from her mom.
“The dentist handed me this piece of paper tha... Read More
Cornell University researchers have found a new tool to help marine biologists better grasp the processes under the sea: They have created mathematical models to unveil the bacterial community dynamics behind afflictions that bleach and kill coral.
The research appears in PLoS Biology, publis... Read More
It's probably the nastiest, slimiest computer in the world. Powered by oat flakes instead of electricity, scientists in the UK have developed a rudimentary computer using a slime mold they have affectionately named Plasmobot.
"Most people's idea of a computer is a piece of hardware with softw... Read More

According to new data presented March 28 at the spring meeting of the Society for General Microbiology, held in Edinburgh, it may be that using microbes to break up plastic is the way to go. Most people tend to consider plastic objects as being disposable, but in fact they can take up to several... Read More
Scientists are learning how our immune system senses and tracks down infection in the body by responding to chemical "scents" emitted by bacteria. Studying how immune cells manipulate their movement in response to external signals could shed light not only on how our immune system functions but ... Read More
Researchers are showing renewed interest in learning how phages interact with bacterial hosts, adapting to and overcoming their defenses. The abundance of phages and their importance to evolution and to ecology provide an incentive to study them. The golden era for studying phages stretched from... Read More

The birth of microbiology revolved around many key discoveries beginning around the mid to late 1600’s. These discoveries were at the cutting edge of science at the time and th... Read More
PigContinuing activity of pandemic H1N1 influenza in the Southeast, particularly in Georgia, is raising fears of a third wave of swine flu, federal officials said Monday. They urged people to continue getting vaccinated as a preventive measure in case a new outbreak occurs.
