In the tiny gap between the gold skin and the gold core of the nanoparticle, there is an electromagnetic hot spot that lights up the reporter molecules trapped there. BRIGHTs, which shine about 1.7 x 10^11 more brightly than isolated Raman reporters, are intended for use in noinvasive bioimaging.Tue, 20 Nov 2012 15:24:24 ESThttp://www.sciencedaily.com/releases/2012/11/121120152411.htmRibosome regulates viral protein synthesis, revealing potential therapeutic targethttp://www.sciencedaily.com/releases/2012/11/121120132906.htm Rather than target RNA viruses directly, aiming at the host cells they invade could hold promise, but any such strategy would have to be harmless to the host. Now, a surprising discovery made in ribosomes may point the way to fighting fatal viral infections such as rabies.Tue, 20 Nov 2012 13:29:29 ESThttp://www.sciencedaily.com/releases/2012/11/121120132906.htmImpulsivity in first grade predicts problem gambling in late teen years for urban boyshttp://www.sciencedaily.com/releases/2012/11/121120132859.htm A developmental pattern of impulsiveness in young males is linked with gambling problems in late adolescence. Respondents considered to be in the high impulsivity track as early as first grade doubled the odds of meeting criteria for at-risk/problem gambling, and tripled the odds of meeting criteria for problem gambling. The study is the first to link a developmental pattern of impulsivity and late-adolescent gambling.Tue, 20 Nov 2012 13:28:28 ESThttp://www.sciencedaily.com/releases/2012/11/121120132859.htmWell-known protein implicated in fibrosishttp://www.sciencedaily.com/releases/2012/11/121120122043.htm Scientists have uncovered a new role for the protein toll-like receptor four in the development of tissue fibrosis, or scarring.

Scientists find answers in the nosehttp://www.sciencedaily.com/releases/2012/11/121120121835.htm Microbiologists studying bacterial colonization in mice have discovered how the very rapid and efficient spread of antibiotic resistance works in the respiratory pathogen, Streptococcus pneumoniae (also known as the pneumococcus). The team found that resistance stems from the transfer of DNA between bacterial strains in biofilms in the nasopharynx, the area just behind the nose.Tue, 20 Nov 2012 12:18:18 ESThttp://www.sciencedaily.com/releases/2012/11/121120121835.htmSweat glands play major role in healing human woundshttp://www.sciencedaily.com/releases/2012/11/121120100432.htm Researchers have discovered one of the body's most powerful secret weapons in healing: sweat glands.Tue, 20 Nov 2012 10:04:04 ESThttp://www.sciencedaily.com/releases/2012/11/121120100432.htmDiscovery of molecular pathway of Alzheimer's disease reveals new drug targetshttp://www.sciencedaily.com/releases/2012/11/121120100430.htm The discovery of the molecular pathway that drives the changes seen in the brains of Alzheimer's patients is reported today, revealing new targets for drug discovery that could be exploited to combat the disease.

Researchers report that these new stem-like cells do not express the same genes as embryonic stem cells and induced pluripotent stem cells (iPSCs) do. That explains why they don't produce tumors when they grow in the laboratory, as the other stem cells do, and why they are stable, producing the kind of cells researchers want them to.Mon, 19 Nov 2012 15:13:13 ESThttp://www.sciencedaily.com/releases/2012/11/121119151314.htmBody may be able to 'coach' transplanted stem cells to differentiate appropriatelyhttp://www.sciencedaily.com/releases/2012/11/121119151308.htm Pluripotent stem cells are nature's double-edged sword. Because they can develop into a dizzying variety of cell types and tissues, they are a potentially invaluable therapeutic resource. However, that same developmental flexibility can lead to dangerous tumors called teratomas if the stem cells begin to differentiate out of control in the body.Mon, 19 Nov 2012 15:13:13 ESThttp://www.sciencedaily.com/releases/2012/11/121119151308.htmHow yeast protein breaks up amyloid fibrils and disordered protein clumpshttp://www.sciencedaily.com/releases/2012/11/121119151220.htm Hsp104, an enzyme from yeast, breaks up both amyloid fibrils and disordered clumps. For stable amyloid-type structures, Hsp104 needs all six of its subunits, which together make a hexamer, to pull the clumps apart. By contrast, for amorphous, non-amyloid clumps, Hsp104 required only one of its six subunits.Mon, 19 Nov 2012 15:12:12 ESThttp://www.sciencedaily.com/releases/2012/11/121119151220.htmExperimental drug improves memory in mice with multiple sclerosishttp://www.sciencedaily.com/releases/2012/11/121119151218.htm Researchers report the successful use of a form of MRI to identify what appears to be a key biochemical marker for cognitive impairment in the brains of people with multiple sclerosis (MS).

Researchers found that a shortage of the genetic factor KLF4, which regulates endothelial cells lining the interior of blood vessels, makes the lining more prone to the buildup of plaque and fat deposits. Further, the deficiency made the blood vessel more susceptible to clot formation.Mon, 19 Nov 2012 11:43:43 ESThttp://www.sciencedaily.com/releases/2012/11/121119114300.htm3-D light switch for the brain: Device may help treat Parkinson's, epilepsy; aid understanding of consciousnesshttp://www.sciencedaily.com/releases/2012/11/121119114249.htm A new tool for neuroscientists delivers a thousand pinpricks of light to individual neurons in the brain.
