Researchers develop technique to concentrate, manipulate and separate a wide class of swimming bacteria

The technique is based on the transmission of tiny electric current in a very thin film sample cell containing a colony of bacteria. The current produces electrolysis that changes the local pH level in the vicinity of the electrodes.

Researchers observer proteins important in Alzheimer's, Parkinson's moving along axons

Using a novel video-imaging system, researchers at the University of Pennsylvania School of Medicine have been able to observe proteins important in Alzheimer's and Parkinson's disease moving along axons, extensions of nerve cells that carry proteins away from the cell body.

Chemicals in cruciferous vegetables may provide cancer-fighting benefit

Chemicals in cruciferous vegetables, such as broccoli, watercress, cabbage and cauliflower, appear to not only stop human prostate cancer cells from growing in mice but also may cut off the formation of blood vessels that "feed" tumors, says a University of Pittsburgh Cancer Institute study.

Bacteria barge inside guard cells and initiate a powerful immune response

Immune cells that are the body's front-line defense don't necessarily rest quietly until invading bacteria lock onto receptors on their outside skins and rouse them to action, as previously thought.

Nanoparticles could damage DNA and lead to cancer

Tissue studies indicate that nanoparticles, engineered materials about a billionth of a meter in size, could damage DNA and lead to cancer, according to research presented at the 2007 Annual Meeting of the American Association for Cancer Research.

Better understanding of membrane fusion

Cells constantly swap cargo bound in vesicles, miniscule membrane-enclosed packages of proteins and other chemicals. Before the swap can take place, the vesicle membrane must fuse with another membrane, creating channels packages can pass through.

Selenium as therapy for prostate cancer

Selenium may offer an intervention strategy for the treatment of prostate cancer according to results of a study from the laboratory of Allen Gao, PhD, which will be presented by Yan Hu, PhD, Departments of Medicine and Pharmacology and Therapeutics, Roswell Park Cancer Institute (RPCI) at the 2007 centennial meeting of the American Association for Cancer Research (AACR), April 14-18, in Los Angeles, CA.

Controlling impact of Ebola - new vaccines could control impact of Ebola on wild apes

Why have large outbreaks of Ebola virus killed tens of thousands of gorillas and chimpanzees over the last decade? Observations published in the May issue of The American Naturalist provide new clues, suggesting that outbreaks may be amplified by Ebola transmission between ape social groups.
