Flu activity is coming down in all regions of the country, the Centers for Disease Control and Prevention said Friday, though it is still rising in H... Read More
Titanium dioxide nanoparticles, found in everything from cosmetics and sunscreen to paint and vitamins, caused systemic genetic damage in mice, according to a comprehensive study conducted by researchers at UCLA's Jonsson Comprehensive Cancer Center.
Titanium dioxide (TiO2) nanoparticles indu... Read More
Colorful cave deposits long thought to be ordinary minerals are actually mats of waste excreted by previously unknown types of microbes, scientists say. The microbes were found on the walls of lava tubes in Hawaii, New Mexico, and the Portuguese Azores islands, a volcanic archipelago in the Atla... Read More
The ASM Public Communications Award, sponsored by ASM, recognizes outstanding achievement in increasing public awareness, knowledge and understanding of microbiology. Microbiology is concerned with issues such as the environment, prevention and treatment of infectious diseases, laboratory and di... Read More
As U.S. health officials struggle to vaccinate tens of millions of Americans against the pandemic of swine flu, some are looking regretfully at one easy way to instantly double or triple the number of doses available -- by using an immune booster called an adjuvant.
These additives, often as ... Read More
CNN is reporting Procter & Gamble is recalling Vicks Sinex nasal spray in the United States, Britain and Germany after finding it contained bacteria, the company said.

Mounting evidence has emerged in recent years that doctors wearing ties might actually cause as much harm to patients as doctors who don't wash their hands. In one 2004 study of 42 doctors and medical staffers at the New York Hospital Medical Center of Queens, almost 50 percent of the neckties w... Read More
A mysterious bowel disease thought to be caused by an over-exuberant immune system may paradoxically be triggered by immune cells that don't do enough in the early stages of bacterial infection.
Since some treatments for Crohn's disease aim to suppress the immune system, it's possible these d... Read More
Cigarettes are "widely contaminated" with bacteria, including some known to cause disease in people, concludes a new international study conducted by a University of Maryland environmental health researcher and microbial ecologists at the Ecole Centrale de Lyon in France.
The research team de... Read More
There have been about 40 deaths worldwide among people who have recently been vaccinated against pandemic H1N1 influenza, but there is no evidence the deaths are related to the vaccine, officials from the World Health Organization said today.

Diarrhea doesn't make headlines. Nor does pneumonia. AIDS and malaria tend to get most of the attention.
Yet even though cheap tools could prevent and cure both diseases, they kill an estimated 3.5 million kids under 5 each a year globally — more than HIV and malaria combined.
"They have b... Read More
Food production of modern human societies is mostly based on large-scale monoculture crops, but it now appears that advanced insect societies have the same practice. Our societies took just ten thousand years of (mainly cultural) evolution to adopt this habit and we are far from convinced that i... Read More
A high-fat, high-sugar diet can quickly and dramatically change the population of microbes living in the digestive tract, according to a new study of human gut bugs transplanted into mice.
Trillions of microbes live inside the human gut, and one of their functions is to process parts of foods... Read More
A new study suggests that tooth-binding micelles (or particles) may provide long-term cavity protection by adhering to tooth surfaces and gradually releasing encapsulated antimicrobials. Formulation of a mouthwash-based delivery system is anticipated, ultimately simplifying application and incre... Read More
In a new research, scientists have found that ant farmers, like their human counterparts, depend on nitrogen-fixing bacteria to make their gardens grow.
The finding documents a previously unknown symbiosis between ants and bacteria and provides insight into how leaf-cutter ants have come to d... Read More
