Jonathan Pinsky, Cofounder of Violight, shows the first ever UV cell phone sanitizer. He demonstrates the sanitizer on my Nokia N86. Place your phone inside the portable sanitizer for three minutes and it'll eliminate up to 99.9% of germs and bacteria on your cell phone and other small electroni... Read More
Never underestimate the power of the field trip. Turns out, visiting real scientists doing real science had a big impact on what one group of seventh graders thought scientists looked and acted like.
The kids drew and captioned pictures before and after their trip. One of the first things tha... Read More

We are what we eat, but who are "we"? New, high-powered genomic analytical techniques have established that as many as 1,000 different single-celled species coexist in relative harmony in every healthy human gut.
"For each human cell in your body there are 10 microbial cells, most of them liv... Read More
In response to consumer demand for more natural food, the food industry has reduced the amount of preservatives in food over recent years. A common preservative is acetic acid, which is used to stop bacterial growth in dressings, sauces, cheese and pickles.
However, new research shows that a ... Read More
Exposure to high levels of fungus may increase the risk of severe asthma attacks among people with certain chitinase gene variants, according to a study from Harvard Medical School, Harvard Pilgrim Health Care Institute and Brigham and Women's Hospital.

Widespread vaccination has gone a long way toward curbing whooping cough, a highly contagious infection that can be especially dangerous for babies too young to be immunized.
Already this year, though, whooping cough has claimed the lives of five infants, all of them less than 3 months old. I... Read More
It was a night of culture - yoghurt cultures. Vaughn Tan shared his passion for yoghurt with about two dozen captivated future yoghurt makers. He spoke about the biochemistry and microbial ecology of the process - ways to optimize the proteins in the milk, effects of inoculation temperatures, th... Read More
Pseudomonas aeruginosa is a common bacterium which can cause disease in animals and humans.
An equal opportunity offender, it uses a wide range of organic material for food; in animals, this versatility enables 'ol Pseudomon here to infect damaged tissues or people with reduced immunity.

For almost three decades, oceanographers have been puzzled by the ability of microscopic algae ("microalgae") to grow in open-ocean areas where there is very little nitrate, an essential nutrient for the algae.
In this week's issue of the journal Nature, Monterey Bay Aquarium Research Institu... Read More
The 2001 anthrax attacks in the United States are fostering development of a new generation of vaccines, antibiotics, and other medications to protect people against the potentially deadly bacteria in any future bioterrorist incident. That's the conclusion of a sweeping overview of scientific re... Read More
When I first saw the title of this PloSOne article, "Unauthorized Horizontal Spread in the Laboratory Environment: The Tactics of Lula, a Temperate Lambdoid Bacteriophage of Escherichia coli", I thought, "Hunh?!? You can actually publish articles about laboratory contamination?", but it's actual... Read More

The idea of friendly bacteria might take a little getting used to, but these microorganisms have been around for a quite a while. Now probiotics are being researched for their potential benefits, as well as side effects.
Here is some information about probiotics from The National Center for C... Read More
The adapted virus that immunized hundreds of millions of people against smallpox has now been enlisted in the war on cancer. Vaccinia poxvirus joins a herpesvirus and a host of other pathogens on a growing list of engineered viruses entering late-stage human testing against cancer.
After a de... Read More
A team of molecular biologists and computer scientists at Stony Brook University have used a novel method to weaken (attenuate) influenza virus by way of designing hundreds of mutations to its genetic code to create an effective vaccine.
The research is an outgrowth of years of investigation ... Read More
Eminent Australian scientist Professor Frank Fenner, who helped to wipe out smallpox, predicts humans will probably be extinct within 100 years, because of overpopulation, environmental destruction and climate change.
Fenner, who is emeritus professor of microbiology at the Australian Nationa... Read More
The mucosal immune system, which stands like a military battalion protecting the nasal passages, intestinal lining, and other vulnerable surfaces of the human body, is often the first to tangle with microbial invaders. It’s also of considerable interest to researchers who hope to improve vaccin... Read More
