Brain

Education was becoming a no-brainer, some people at Harvard’s Graduate School of Education (HGSE) complained.

University of Portsmouth scientists have developed a powerful new tool that 'freezes' the memory of crime scenes in the minds of witnesses.

Researchers at Johns Hopkins have discovered that the same ingredient used in dandruff shampoos to fight the burning, itching and flaking on your head also can calm overexcited nerve cells inside your head, making it a potential treatment for seizures. Results of the study can be found online in Nature Chemical Biology.

In a breakthrough that could make the production of cellulosic ethanol less expensive, Cornell researchers have discovered a class of plant enzymes that potentially could allow plant materials used to make ethanol to be broken down more efficiently than is possible using current technologies.

Brains are able to adjust automatically to the demands of distinguishing between small differences in smell, new research at the University of Chicago shows.

The research, which was conducted on rats, suggests that the human brain may be more adept at distinguishing smells than previously thought. The work comes from studies in the laboratory of Leslie Kay, Assistant Professor in Psychology at the University, who is looking at the ways animals perceive sensory stimuli by focusing on the neural basis of olfactory perception and how context and experience influence it.

A unique pattern of gene expression observed in rats may be linked to a conditioned desire for food and excessive food intake, an article published today in BMC Biology suggests.

Put a human and a chimpanzee side by side, and it seems obvious which lineage has changed the most since the two diverged from a common ancestor millions of years ago. Such apparent physical differences, along with human speech, language and brainpower, have led many people to believe that natural selection has acted in a positive manner on more genes in humans than in chimps.

But new research at the University of Michigan challenges that human-centered view.

Sleep not only protects memories from outside interferences, but also helps strengthen them, according to new research.

Termites know how to digest cellulose, but the human process of producing ethanol from cellulose is slow and expensive. The bottleneck is the rate at which the cellulose enzyme breaks down cellulose into sugars, which are then fermented into ethanol.

Parents-to-be might soon don 3-D glasses in the ultrasound lab to see their developing fetuses in the womb "in living 3-D, just like at the IMAX movies," according to researchers at Duke University's Pratt School of Engineering.

The same Duke team that first developed real-time, three-dimensional ultrasound imaging says it has now modified the commercial version of the scanner to produce an even more realistic perception of depth. Paired images seem to pop out of the screen when viewed with the special glasses.
