The trust game: Measuring social interaction
...hen researchers at Baylor College of Medicine have mapped where in the brain that trust is formulated and how the decision to trust shifts with experience. In a report in this week's issue of the journal Science, Dr. P. Read Montague Jr. and colleagues at the BCM Human Neuroimaging Laboratory and California...Brain imaging study may hold clues to onset of schizophrenia in people at high risk

"Our goal was to see if the high-risk individuals showed normal brain activity during these executive tasks or whether or no...Newly identified gene cluster on mouse X chromosome provides insights into fertility

A 2000 paper that mapped out the stages of age-related sleep deterioration and showed how changes in sleep were mirrored by changes in hormone secretion, which in turn reduced sleep quality. A 2001 study demonstrating that inadequate sleep could foster insulin-resistance, ...Envisat Symposium day one: Steady symphony of Europe's largest satellite

...up to 30 cm. Such sea height anomalies can then be mapped with space-based radar altimeter data." Radar altimeters, such as the Radar Altimeter-2 instrument on Envisat, fire hundreds of radar pulses down to Earth every second, and by timing their return down the nanosecond can measure sea height to a maxim...Pediatricians are plentiful, but not in poorer states
... at meeting that demand." But when the researchers mapped the number of pediatricians per 100,000 children in each state, they noticed a stark trend: much higher concentrations, as many as 165 pediatricians per 100,000 children in some states, and concentrations as low as 28 pediatricians per 100,000 childr...Researchers induce temporary blindness to learn more about vision

Prior to the tests, the researchers mapped each participant's visual cortex the area at the back of the brain that processes what the eye sees with transcranial magnetic stimulation (TMS), a harmless noninvasive technique using brief magnetic pulses. When applied to the visual cortex, TMS i...New hereditary gene linked to Parkinson's disease
...earch centres, published today in Science Express, mapped the genes in two Italian and one Spanish family where cousins had married and produced offspring. Following earlier work tracing the chromosome location of the gene responsible for this form of familial Parkinson's disease, researchers were able to p...Tuberculosis strains stay close to home, say Stanford researchers
...r groups. "It was remarkable how well the genetics mapped to global geography," said Small. "Co-evolution is highly speculative, but it's an intriguing possibility. Most importantly, it's a hypotheses we now have the technology to address." Tuberculosis causes more adult deaths than any other infectious dis...Brain area identified that weighs rewards
... that produced them," said Platt. "So, once we had mapped the regions of the posterior cingulate cortex that responded to specific regions of visual space, we wanted to find out whether these neurons were representing how valuable movements to that region of space were. "We manipulated how much fruit juice ...Scientists map maturation of the human brain
For the first time, scientists have mapped the progressive maturation of the human brain in childhood and adolescence. In other studies, they have made advances in understanding during adolescence the effects of stress, nicotine, and alcohol. Scientists at the National Institute of Mental Hea...Jefferson and Michigan scientists identify gene defect behind muscle-wasting disease
...ly, that same chromosome region in humans has been mapped in certain patients with Parkinson's disease," Dr. Alnemri notes. "We tested a few of these Parkinson's samples but we did not find mutations in Omi. We still don't know if this gene is mutated in other types of Parkinson's or different neurodegenera...Research offers insight on treatment for hereditary eye disease

Researchers then mapped those changes using crystal structure-based molecular modeling to locate the specific areas on the rhodopsin protein where the mutations took place. Once the location of the mutations was known, the researchers introduced new amino acids to attempt ...$2 million federal grant to study cancer drug action
...uticals work against parts of cancer cells. "We've mapped the cell pathways, and we have created the world's largest computer simulation of a human cancer cell. However, we need to generate more biological data to confirm how our simulation works. This grant helps pay for that research," says co-founder Col...Children in deprived areas three times more likely to be hit by a car

The research found that the numbers of child pedestrian accidents in deprived areas is far more than would be expected, even taking into account the increased risk in urban areas. The report recomm...Location of gene for ear wax could increase understanding of apocrine-gland development
... Hiroaki Tomita comments: "The region to which we mapped the earwax locus is included in the region associated with paroxysmal kinesigenic choreoathetosis, therefore the two loci should be close to each other. Identification of the earwax locus could contribute to further anthropogenetic studies and to phy...Gene linked to testicular cancer
... gene in abnormally high levels. The hiwi gene was mapped to a region on the long arm of chromosome 12, which was previously linked by Lin's collaborators in the Netherlands to the development of seminomas and other testicular cancers.

...ion of the gene, LRP5. Lifton said he and his team mapped the gene in the family to the same chromosome segment in LRP5. "It made us wonder if a different mutation increased LRP5 function leading to an opposite phenotype, that is, high bone density," Lifton said. Bone mass increases during childhood and pea...
