Researchers Discover That Microbes Can Produce Miniature Electrical Wires

...nteresting implication of this research is that it suggests a mechanism for microbes to share energy in a mini-power grid. The nanowire pili of individual Geobacter often intertwine, suggesting a strategy by which Geobacter might share electricity. Geobacter was discovered by Lovley in 1987 at the muddy bott...

Purdue scientists may have found key to halting spinal cord damage

A protein in the eye may prevent immune response and protect eyes from disease

... and its exclusion from T cell zones in the spleen suggests that F4/80 expression and immune activation may be mutually exclusive. According to Stein-Streilein, the next steps for the group will be to tease out exactly how the protein accomplishes its goal. Ultimately knowledge of the F4/80 protein and its r...

Study: Harmless virus kills some cancers

... cancer cells are abnormal and destroys them. This suggests that AAV2 has great potential to be developed as an anti-cancer agent." The study was presented June 20, 2005, at the 24th annual meeting of the American Society for Virology held June 18-22 at Penn State, University Park campus. Although the reaso...

A virus-like hitchhiker may trigger bacterial meningitis

...It may help the bacteria get into the bloodstream, suggests Tinsley, either by altering the bacteria or by disrupting the immune response that normally protects against it. ...

Neandertal femur suggests competition with hyenas and a shift in landscape use

...tely 41,000-year-old human remains found in France suggests that Neandertals may have become regionally mobile earlier than scientists once thought. Cédric Beauval and colleagues from Université Bordeaux 1 in France, Max Planck Institute in Germany, and Washington University in St. Louis, conclude that the h...

Human embryonic stem cells have the potential to develop into eggs and sperm in the laboratory

...ressed proteins only found in maturing sperm. This suggests that HESCs may have the ability to develop into PGCs and early gametes as has been shown previously for mouse embryonic stem cells." However, Mr Aflatoonian stressed that there was still a lot of work to be done before the promise of these early res...

New protein vital for immune response is found in surprise location

...at MAVS is located in the membrane of mitochondria suggests it may play a role in coordinating cell death and immune response, Dr. Chen said. Secondly, many scientists believe that mitochondria originally evolved from bacteria that lived within a host organism's cells, eventually developing a symbiotic relat...

OHSU research shows vitamin C counteracts some negative impacts of smoking on unborn babies

...ch Center, Oregon Health & Science University, suggests high doses of vitamin C may have potential to counteract some negative impacts of smoking in unborn babies. The research may benefit thousands of babies born to mothers who continue to smoke throughout pregnancy despite physician warnings. The resear...

Scientists discover stem cell origin of neck and shoulders

...omponents of vertebrate organisation. Our research suggests this is wrong and actually groups of stem cells create not only the muscles of the neck and shoulder but also the skeletal structure where these muscles are attached. These groups of stem cells are making scaffolds of connections early during embryon...

'Punctuated' evolution in the human genome

...centromeric regions among closely related primates suggests extraordinary dynamism, where duplication, deletion, and rearrangement of large segments of DNA occur at an unprecedented scale. Eichler's group performed a comprehensive structural and evolutionary analysis of a 700-kilobase (Kb) pericentromeric re...

Divergent life history shapes gene expression in brains of salmon

...nces between sneakers and other salmon. Their work suggests that the "default" life cycle, in which male salmon spend several years in oceans before returning to freshwater to reproduce, may actually result from active inhibition of development into a sneaker. Previous studies have found that the proportion o...

University of Nevada, Reno research team discovers hormone that causes malaria mosquito to urinate

... only affects lower species such as insects, which suggests it should be very safe to non-insect species." Schooley said that discovery, development and extensive environmental testing of such a pesticide could take up to 10 years, however. ...

Insulin pulses keep the liver lean

... fat-building hormone normally stays trim and also suggests new dietary strategies and treatments to avoid fatty liver, a growing healthcare epidemic, said the researchers. Insulin produced by the pancreas allows cells to take up glucose from the bloodstream and burn it for energy. In the liver, insulin prom...

Elevated temperature enhances success of viral cancer therapy

...hown promise in clinical trials. Now, new research suggests that fever might be a useful weapon in the fight as well. The study, published in the July issue of Cancer Cell, demonstrates that tumor cells are even more sensitive to viral therapy after they have been incubated at an elevated temperature. The fin...

New lead reported in tumor angiogenesis

...n and senior author on the paper, said the finding suggests a future anti-angiogenic strategy of blocking not only the secreted molecules but also the cell-to-cell contact. Wang said these early data also suggest the intriguing possibility of directing growth-inhibiting drugs at the normal blood vessel cells...

Stem Cells Found In Cerebellum; Possible Cell of Origin for Childhood Brain Tumors

...The Duke discovery of stem cells in the cerebellum suggests a possible origin for these normal cells and provides a starting point for understanding the basis of medulloblastoma, the most common malignant brain tumor in children, said the researchers. Medulloblastomas arise in the cerebellum but their cells ...
