The first comprehensive analysis of the clinical effects of genetic mutations involved in Rett syndrome will enable affected families to receive a more accurate indication of their child's prognosis.
Rough-skinned newts harbor in their skin massive doses of the same deadly toxin found in blowfish. Garter snakes that dine on the newts have evolved resistance to the toxin, spurring greater toxicity in the newts by natural selection. But now researchers report that in some areas, the snakes have somehow evolved levels of resistance far beyond what the newts are capable of countering.
Researchers have made an important neurobiological discovery of how humans learn to predict risk. The research, appearing in the Journal of Neuroscience, will shed light on why certain kinds of risk, notably financial risk, are often underestimated, and whether abnormal behavior such as addiction (e.g. to gambling or drugs) could be caused by an erroneous evaluation of risk.
NOAA has just deployed the final two tsunami detection buoys in the South Pacific, completing the buoy network and bolstering the U.S. tsunami warning system. This vast network of 39 stations provides coastal communities in the Pacific, Atlantic, Caribbean and the Gulf of Mexico with faster and more accurate tsunami warnings.
Ultracold atoms moving through a carefully designed arrangement of laser beams will jiggle slightly as they go, two NIST scientists have predicted. If observed, this never-before-seen "jitterbug" motion would shed light on a little-known oddity of quantum mechanics arising from Paul Dirac's 80-year-old theory of the electron.
Myostatin, a protein that blocks muscle growth, has shown promising results as a potential therapeutic target for treating muscular dystrophy in animal studies, where its inhibition led to increased muscle mass and strength. A new study, the first to evaluate a myostatin inhibitor in patients, assessed its safety in adults with muscular dystrophy and found that it was well-tolerated.
Male smokers who consume more magnesium appear to have a lower risk for cerebral infarction, a type of stroke that occurs when blood flow to the brain is blocked, according to a new report.
There is increasing evidence that high rates of illness in Persian Gulf War veterans can be explained, in part, by exposure to certain chemicals, including pesticides and nerve agents.
Bipolar Disorder (BPD or manic-depressive illness) is one of the most serious of all mental disorders, affecting millions of individuals worldwide. Affected individuals alternate between states of deep depression and mania. Now, a mouse model of the disease has been developed. Researchers found that the glutamate receptor 6 (GluR6) gene is associated with bipolar disorder. Mice that were missing the GluR6 gene underwent a series of tests designed to approximate the symptoms of mania. These mice showed many of the symptoms of mania, including hyperactivity, aggressiveness, driven or increased goal-directed pursuits, risk-taking, and super-sensitivity to amphetamine. The researchers also found that treating the mice with lithium -- the classic treatment for bipolar disorder -- reduced these symptoms.
A clever new microscope design allows nanotechnology researchers to track the motions of nanoparticles in solution as they dart around in three dimensions. The researchers hope the technology, which NIST plans to patent, will lead to a better understanding of the dynamics of nanoparticles in fluids and, ultimately, process control techniques to optimize the assembly of nanotech devices.
