Researchers find gene that may be at root of potato blight

... which, depending on the plant variety, can either facilitate disease or trigger resistance. Avr3a scouts a potato plant on the cellular level to determine whether the plant is a likely victim. "This avirulence gene is kind of like a weapon that triggers a metal detector," said Sophien Kamoun, a study co-auth...

Scientists discover how Ebola virus infects cells

Endosomal proteolysis of the Ebola virus glycoprotein is necessary for infection. Science Express. Published online April 14, 2005. DOI: 10.1126/science.1110656. ...

The lopsided brain: Attention bias is shared by humans and birds

..., the structure in human brains that is thought to facilitate rapid communication between the two hemispheres. In the past, such communication via the corpus collosum has been thought to form the basis for asymmetries in human spatial attention, but the new observations suggest that this view warrants reconside...

Norovirus found to cause traveler's diarrhea

...fy Norovirus-positive stool samples could serve to facilitate future Norovirus-related research in developing countries. "Prevalence of Norovirus among U.S. Visitors to Mexico and Guatemala Experiencing Traveler's Diarrhea" was supported by a grant from the Center for a Livable Future at the Johns Hopkins Bloo...

Multiple-drug resistant gene expression pattern predicts treatment outcome for pediatric leukemia

...ed in the April issue of Cancer Cell, is likely to facilitate development of new strategies to combat drug resistance and treatment failure for children with ALL. Nearly 80% of children with ALL are cured following chemotherapeutic treatment. However, the remaining 20% often exhibit drug resistance and treatme...

Cooperation is key—a new way of looking at MicroRNA and how it controls gene expression

...uggests that the RNA binding proteins are there to facilitate the degradation and that microRNA is required as well. They believe that the microRNA and protein form a large complex of molecules, though they do not know exactly how many proteins and other molecules are involved. The article, "Involvement of Mic...

Emergence of cancer as major cause of childhood death in developing countries is not being adequately addressed

... include cases in developing countries. This would facilitate studies of the roles that genetic background, environment and lifestyle play in susceptibility to cancer and pathogenesis of particular cancers. Such studies would be easier to conduct if pediatric cancer units are created in resource-poor nations an...

Strongest proof yet found for prion hypothesis

...SE studies. According to Soto, it should also soon facilitate creating a much-needed blood test for prions, which would greatly improve current surveillance techniques for mad cow disease and its human form, new-variant Creutzfeldt-Jakob Syndrome. ...

PGA on a tour under the skin

...lular polymer called poly-gamma-glutamate (PGA) to facilitate growth and ensure survival of the bacteria inside the human host. PGA protects the pathogen from innate host defenses during infection. S. epidermidis is the only human pathogen known to produce PGA other than Bacillus anthracis, but several differen...

Vampire bats keep out of trouble by running

...h the researchers believe evolved independently to facilitate feeding behavior. "What we observed was like a horse going from a walk to a gallop over a very short amount of time," Riskin explains. The researchers kept increasing the speed of the treadmill and, much to their surprise, their subjects broke into a...

LUCA technologies confirms real-time methane generation

...nument Butte field has a waxy composition that may facilitate the strong real-time methane generation we see at this site," commented Mr. Pfeiffer. "If so, then areas with large accumulations of waxy oil ?for example, the Daqing Field in Northeast China -- could prove to be important sites for the bioconversion...

Protein offers way to stop microscopic parasites in their tracks
