Mosaic mouse technique offers a powerful new tool to study diseases and genetics

...e of interest." In their study, the Stanford team focused on the cerebellum, the part of the brain whose main function is to coordinate motor activity and maintain balance. The researchers used MADM to study the development of cerebellum granule cells, which are the most abundant cells in the brains of mice...

Depression gene may weaken mood-regulating circuit

...nts act by blocking this protein, researchers have focused on possible functional consequences of a slight variation in its DNA sequence across individuals. Everyone inherits two copies of the gene, one from each parent, which comes in two common versions: short and long. The short version makes less protein...

Where Bacteria Get Their Genes

...d from its parent. In their study, the scientists focused on the best-studied group of bacteria, the Gamma-Proteobacteria. It includes many human pathogens, including Salmonella, Shigella, pathogenic E. coli, and Pseudomonas. Ochman's team compared the bacterial species by analyzing their genomic sequence ...

Researchers extend mouse lifespan by protecting against free radicals

... to the free-radical theory. He and his colleagues focused their study on catalase, an enzyme in the body that helps convert hydrogen peroxide into water and oxygen. Hydrogen peroxide is a waste product of metabolism and it can be a the precursor of free radicals that can damage the cell. The damage can in t...

ORNL, UC Berkeley unravel real-world clues to Earth's mysteries

...t relates to its Genomes to Life program, which is focused on identifying and characterizing protein complexes, the molecular machines of life. "Most of the current work looks at single microbial organisms grown under controlled laboratory conditions, but the longer-term plans are to extend this work to rea...

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

...ories became much larger. They became less locally focused and more regionally focused," Trinkaus said. It's been assumed that this happened in the Upper Paleolithic which is associated with some very late Neandertals and early modern humans. However, this is a femur bone from a Middle Paleolithic Neanderta...

Going To Extremes To Improve Human Health

...is more important than ever that some attention be focused on the research-training of individuals who will make sense of the explosion of available information by connecting these discoveries to integrative physiological functions in the intact human being," Halliwill said. ...

Spiders help scientists discover how muscles relax

...of the journal Nature. Padron and his colleagues focused their studies on striated muscle--the type of musc..., the muscle contracts or relaxes. Padron's study focused on the long, rod-shaped myosin of the thick filaments. The heads of these myosin rods project outwar...

Endocannabinoids ?the brain's cannabis ?demonstrate novel modes of action to stress

..., a multi-center Japanese team led by Atsushi Soya focused on the supraoptic nucleus (SON) where vasopressin and oxytocin are synthesized. They found that a synthesized cannbinoid (CP55,940) inhibited both excitatory and inhibitory synaptic transmission and that a balanced input can produce sustained changes...

Spider blood found in 20 million year old fossil

... Plata, Dominican Republic. His research initially focused on the spider which he identified as an entirely new species of spider. On his return to the UK, further research revealed the droplets of blood and the information the fossil contained. ...

Biased reporting found in cancer prognostic studies

...example, at least 116 published studies alone have focused on a single tumor suppressor protein (TP53) that may predict the outcome of a patient with head and neck cancer. As researchers attempt to make sense of the growing mountains of information, some are beginning to question the validity and possible bi...

Study casts doubt on 'Snowball Earth' theory

...tical techniques, Olcott said. So she and her team focused on a drill core of little-known black shale deposits from southeastern Brazil and applied lipid biomarker techniques to identify prehistoric organisms based on the fatty remains of their cell membranes. The team, which included scientists from USC, ...

Researchers uncover E. coli's defense mechanism

...ng more effective medicines. Spiro and colleagues focused their study on the NorR protein and the role it plays in reducing the levels of nitric oxide. In response to nitric oxide, NorR binds to DNA in order to regulate expression of an enzyme that reduces the amount of nitric oxide in the bacteria. Since n...

Logging changed ecological balance for monkeys, damaged health

...or multiple parasitic infections. The researchers focused on three primate species, collecting 1,076 fecal samples from the heavily logged area and from an undisturbed, nearby forest from August 1997 to August 2002 as part of a longitudinal study of logging's impact. The samples came from red-tailed guenon,...

Gene controlling circadian rhythms linked to drug addiction

... tendency to abuse drugs. "Most work on Clock has focused on the brain's master pacemaker, located in a brain area called the suprachiasmatic nucleus," said Dr. Nestler. "The novelty of Dr. McClung's findings is the role Clock plays in brain reward pathways. The next step is to examine Clock and related gen...

Neurologix announces positive results of gene therapy clinical trial in Parkinson's disease
