'Jekyll and Hyde' bacteria offer pest control clue

12-19-2007 · EurekAlert!

New research at the University of York has revealed so-called 'Jekyll and Hyde' bacteria, suggesting a novel way to control insect pests without using insecticides. Scientists in the University's Department of Biology studied the relationship between plant-dwelling insects and the bacteria that live in them -- and discovered an unexpected interaction.

Microbial biofilms evoke Jekyll & Hyde effects
10-26-2007 · EurekAlert!
Microbes such as bacteria tend to live in complex colonies called biofilms, where they can resist antibiotics and cause more problems for the immune system. Biofilms comprising millions of bacteria are at the root of many serious chronic infectious diseases such as cystic fibrosis and periodontal disease, as well as industrial contamination, biofouling and biocorrosion.

Mayo researcher discovers target site for developing mosquito pesticides
12-20-2006 · EurekAlert!
A Mayo Clinic researcher has discovered a target site within malaria-carrying mosquitoes that could be used to develop pesticides that are toxic to the Anopheles gambiae mosquito and other mosquito species. It would not affect humans and other mammals. If supported by further studies, the findings could offer a safer and more effective control of mosquito-borne diseases such as malaria.

When it comes fighting to C. difficile, the Palme d'Or goes to soap and warm water
09-20-2007 · EurekAlert!
Hospitals world-wide battle nosocomial infections on a daily basis. One of the most difficult bacteria to combat is Clostridium.difficile. To help ensure the best control methods possible, Dr. Michael Libman, director of the division of infectious diseases at the McGill University Health Center, studied the most effective ways to eliminate C.difficile bacteria from the hands of health-care workers, with the highest honor going to soap and warm water!

Is there any alternative to control multisteps of ulcers?
10-23-2007 · EurekAlert!
Ulcers are a worldwide challenging disease, and researchers have long been seeking effective antiulcer alternatives. A research group in India has revealed that a bioactive polysaccharide from an edible root, Decalepis hamiltonii, commonly called swallow root, could offer protection at all critical steps of gastric ulcer.

Songbirds offer clues to highly practiced motor skills in humans
12-21-2007 · EurekAlert!
The melodious sound of a songbird may appear effortless, but his elocutions are actually the result of rigorous training undergone in youth and maintained throughout adulthood. His tune has virtually "crystallized" by maturity. The same control is seen in the motor performance of top athletes and musicians. Yet, subtle variations in highly practiced skills persist in both songbirds and humans. Now, scientists think they know why.

Bacteria control how infectious they become, study finds
04-12-2007 · EurekAlert!
The results of a new study suggest that bacteria that cause diseases like bubonic plague and serious gastric illness can turn the genes that make them infectious on or off. Knowing how disease-causing bacteria, like Yersinia pestis and E. coli, do this may one day help scientists create drugs that control the expression of these genes, thereby making the bacteria harmless. The findings appear in the April 13 issue of the journal Molecular Cell.

Scientists offer new view of photosynthesis
05-03-2007 · EurekAlert!
During the remarkable cascade of events of photosynthesis, plants scavenge nearly every photon of available light energy to produce food. In the May 4 issue of Science, an ASU Biodesign Institute team led by Neal Woodbury has published new insights that allow plants or bacteria to harness light energy efficiently even when conditions aren't optimal. The answers may be good news for organic solar cell technology, a low cost alternative to traditional silicon solar cells.

In nature, proteins sweep up nanoparticles
06-14-2007 · EurekAlert!
Here's a pollution-control tip from nature: Deep inside a flooded mine in Wisconsin, scientists from several institutions including the US Department of Energy's Lawrence Berkeley National Laboratory have discovered a world in which bacteria emit proteins that sweep up metal nanoparticles into immobile clumps. Their finding may lead to innovative ways to remediate subsurface metal toxins.
