Mutation improves memory, may lead to memory-enhancing pill

..., they reported. "For example, if a person were reading a page of a textbook, it might take several times to memorize it," Costa-Mattioli said. "A human equivalent of these mice would get the information right away." The mutant mice also performed better than normal mice in a "fear-conditioning" test. ...

Why doesn't the immune system attack the small intestine?

...n a way that puts the immune system "at ease." By reading those antigens without being on alert, the immune system's T cells learn that such cells are off-limits to attack. For years, scientists have wondered whether the same mechanism is at work in tissues that come in regular contact with bacteria and o...

Sleep disturbances affect classroom performance

Avoid taking naps after school if you can. If you need to lie down, do not do so for more than an hour. Keep a regular schedule....

Scientists reveal structure of gateways to gene control

... to help push the nucleosome out of the way so the reading of the gene can begin," Pugh said. "Previous research had indicated that DNA sequences located upstream of a gene might be a region that controls whether that gene is read or not, but we did not know the architecture of those sequences -- whether ...

'The eyes have it' -- Autism research yields surprising results

...en and adolescents with autism may have difficulty reading mental states from facial expressions but our results suggest that this is not due to an inability to interpret information from the eyes. "Surprisingly, autistic children seemed particularly reliant on the eyes and also the mouth when making ment...

Detailed 3-D image catches a key regulator of neural stem cell differentiation in action

...e, Scp1 prevents the enzyme RNA polymerase II from reading and switching on neuronal genes in tissues where they shouldn't be expressed, such as skin, muscle and liver. In the nervous system Scp1 is switched off, enabling RNA polymerase II to efficiently transcribe information encoded by neuronal genes and d...

Unraveling where chimp and human brains diverge

...ned each gene individually, it would be similar to reading every fifth word in a paragraph ?you don't get to see how each word relates to the other. So instead we used a systems biology approach to study each gene within its context." The scientists identified networks of genes that correspond to speci...

Biologists probe the machinery of cellular protein factories

...ions for making those proteins. The crucial job of reading the genetic instructions and synthesizing the specified proteins is carried out by ribosomes, tiny protein factories humming away inside the cells of all living things. Harry Noller, the Sinsheimer Professor of Molecular Biology at the University o...

New tool helps blood specialists improve patient care

...ures are not passive learners. They are not simply reading about how to improve patient care ?they will be doing it," said Steven Allen, MD, a member of the ASH Committee on Practice, which is developing new parameters for measuring performance on the treatment of several blood disorders and cancers. "Partic...

Boston University biomedical engineers win major grant for pursuit of the '$1,000 Genome'

...," said Meller. "From there, it is a small step to reading tens, and later hundreds, at a time. That would produce an orders-of-magnitude reduction in the cost of sequencing individuals' DNA." According to NIH, sequencing the 3 billion base pairs on a human genome using current technology costs about $10 m...

Reading Shakespeare has dramatic effect on human brain

If it is easy to see which pieces slot together you become bored of the game, but if the pieces don't appear to fit, when we know th...

Technology for monitoring fetal oxygen during labor offers no apparent benefit

The women were randomly assigned to one of two groups: an "open" group, in which oxygen levels were continuously...

New biochip helps study living cells, may speed drug development
