Nanoengineers invent new biomaterial that more closely mimics human tissue. Thursday, May 26, 2011 A new biomaterial designed for repairing damaged human tissue doesn’t wrinkle up when it is stretched.
The invention from nanoengineers at the University of California, San Diego marks a significant breakthrough in tissue engineering because it more closely mimics the properties of native human tissue.

A new biomaterial designed for repairing damaged human tissue doesn't wrinkle up when it is stretched. The new biomaterial was created using a new biofabrication platform that Chen is developing under a four-year, $1.5 million grant from the National Institutes of Health. "We are also exploring other opportunities," said Chen. Shape turned out to be essential to the new material's mechanical property. Twitter Directory and Search, Find Twitter Followers.

[Brown University] — Researchers at Brown University have found that specific genetic variations can predict how persistently people will believe advice they are given, even when it is contradicted by experience. The story they tell in a paper in the April 20 issue of the Journal of Neuroscience is one of the byplay between two brain regions that have different takes on how incoming information should influence thinking. Researchers including Michael Frank, assistant professor of cognitive, linguistic, and psychological sciences at Brown, have studied the striatum intensely, but have been curious about the effect that the advice-influenced PFC has on its function. To conduct the experiment, the researchers recruited more than 70 people who gave saliva samples and then performed a computerized learning task. 'First Comprehensive Gene Map' of the Brain Shows How Genes Express Themselves Neurologically. The Allen Institute for Brain Science has completed what it is calling the first comprehensive gene map of the human brain as part of its development of the Allen Human Brain Atlas, a public resource that it hopes will accelerate clinical understandings of how the human brain works.
The genetic mapping of two human brains showed a striking 94 percent similarity between the two, which could help researchers establish patterns and otherwise figure out in which parts of our brains to look for different expressions of genetic differences. The idea behind the brain atlas is to develop a tool that researchers can access to determine how the genome is expressed in the brain, a process which is--needless to say--complex. Over four years, the ABI crunched more than 100 million data points to pinpoint 1,000 different anatomical sites in the brain that exhibit particular gene expression. That last part is key for research purposes.
