Jason Tetro: Why don’t we ever get 100% kill?

07/26/2010
Over the last year, there has been a question on the minds of thousands of people that continues to be for the most part unanswered: Why do disinfectants and hand sanitizers kill only 99.9% of germs and not the full 100%? Or, more succinctly, why is there always 0.1% survival?

Scientists discover how deadly fungal microbes enter host cells

07/22/2010
A research team led by scientists at the Virginia Bioinformatics Institute (VBI) at Virginia Tech has discovered a fundamental entry mechanism that allows dangerous fungal microbes to infect plants and cause disease. The discovery paves the way for the development of new intervention strategies to protect plant, and even some ...

New antibacterial material for bandages, food packaging, shoes

07/21/2010
A new form of paper with the built-in ability to fight disease-causing bacteria could have applications that range from anti-bacterial bandages to food packaging that keeps food fresher longer to shoes that ward off foot odor. A report about the new material, which consists of the thinnest possible sheets of ...

Frog killer caught in the act

07/20/2010
The first before-and-after view of an amphibian die-off has just been published by scientists working at the Smithsonian Tropical Research Institute in Panama. Like a wave, the fungal disease that wipes out frogs—chytridiomycosis—advances through the Central America highlands at a rate of about 30 kilometers per year. After the disappearance of ...

Of bugs and brains: Researchers discover that gut bacteria affect multiple sclerosis

07/20/2010
Biologists at the California Institute of Technology (Caltech) have demonstrated a connection between multiple sclerosis (MS)—an autoimmune disorder that affects the brain and spinal cord—and gut bacteria.

Computer program predicts MRSA's next move

07/20/2010
Researchers at Duke University Medical Center are using computers to identify how one strain of dangerous bacteria might mutate in the same way a champion chess player tries to anticipate an opponent's strategies.

Vaccine-delivery patch with dissolving microneedles eliminates 'sharps'

07/19/2010
A new vaccine-delivery patch based on hundreds of microscopic needles that dissolve into the skin could allow persons without medical training to painlessly administer vaccines – while providing improved immunization against diseases such as influenza.

Microbial world's use of metals mostly unmapped

07/19/2010
A new way of surveying microbes for the metals they contain reveals that biologists have been relying on the equivalent of a 15th century map of the world.
