On the golf tee or pitcher's mound, brain dooms motion to inconsistency

...the same conditions. "The nervous system was not designed to do the same thing over and over again," Churchland says. "The nervous system was designed to be flexible. You typically find yourself doing things you've never done before." The value of p...

Mayo Clinic study suggests that a central nervous system viral infection can lead to memory deficits

...e virus had difficulty learning to navigate a maze designed to test various components of spatial memory. The degree of memory impairment, which ranged from no discernable damage to complete devastation, was directly correlated to the number of dead brain cells in the hippocampus region of the mouse's brain. ...

H9N2 avian flu vaccine paired with adjuvant provokes strong human immune response at low doses

...o stimulate an immune system response, and are not designed to determine whether the vaccine would prevent infection by naturally occurring virus. The researchers vaccinated 48 volunteers with non-adjuvanted H9N2 vaccine (made from inactivated virus) at one of four dosages--3.75, 7.5, 15 or 30 micrograms. An ...

MIT creates 3-D scaffold for growing stem cells

...ree-dimensional scaffold of tiny protein fragments designed to be more like a living body than any other cell culture system. An MIT engineer and Italian colleagues will report the invention-which may one day replace the ubiquitous Petri dish for growing cells-in the Dec. 27th issue of the PLoS ONE. Shuguang...

Gene therapy study takes aim at prostate cancer

... of the disease. The first phase of the study is designed to test the safety of the treatment and determine the proper dosage of gene, said Dr. Dov Kadmon, professor of urology at BCM. It will be carried out in the department of urology at BCM as well as at Ben Taub General Hospital, The Methodist Hospital ...

MIT nanoparticles may help detect, treat tumors

... can be triggered to group together by a mechanism designed by the MIT engineers. Specifically, certain enzymes, or proteases, inside the tumors cause the nanoparticles to "self-assemble" or stick together. The resulting nanoparticle clumps are too big to get back out of the gaps. Further, the clumps have a s...

P(acman) takes a bite out of deciphering Drosophila DNA

...three recently developed technologies: a specially designed bacterial artificial chromosome (BAC) that allows maintenance of large pieces of DNA in bacteria, recombineering that allows the manipulation of large pieces of DNA that can then be inserted into the genome of the fly at a specific site using phiC31-...

Embryo tests give parents the choice

...plantation genetic diagnosis (PGD), was originally designed to test for severe or deadly diseases such as Tay-Sachs. It is typically performed by removing a cell from a three-day-old embryo, which is then screened for a range of chromosomal abnormalities or specific gene mutations. Seemingly healthy embryos a...

Parasitic plants sniff out hosts

...er seedlings, out of view so to speak, in a set-up designed to block possible light cues. The researchers observed a growth response toward the tomato plants similar to that in their first experiment. Finally, to firmly establish that volatile chemicals from the host plant were causing this response, the re...

Tastes great! Study shows brain's response to pleasing -- and changing -- tastes

...s represented in brain activity." The study was designed so that the signals from the ventral pallidum were only related to the "liking" ?or disliking ?of the taste, and not to a salt-seeking drive or movement. The ventral pallidum is part of the limbic system of the brain, which is involved in motor-muscl...

Major cancer study aims to identify protein markers for early-stage disease

...rd studies aimed at early detection of cancer, are designed to lead to the discovery of many such biomarkers, the scientists say. The grants have been issued under the NCI's Clinical Proteomic Technology Assessment for Cancer program, part of its five-year Clinical Proteomic Technologies Initiative for Canc...

"The measles virus we are using in the glioblastoma multiforme trial provides a noninvasive way to monitor viral effects in the ...

MRSA vaccine shows promise in mouse study

By 2004, 63 percent had learned to resist the antibiotics commonly used to treat them. While such methicillin-resista...

Results with newer bladeless LASIK equivalent to standard microkeratome LASIK

...he bladeless technique, although our study was not designed to compare risks," he says. "Bladeless LASIK is potentially safer because of its computer-controlled precision, the ability to visualize the flap being created, and to stop the procedure whenever necessary. That said, however, the risk of complicatio...

Light-sensitive photoswitches could restore sight to those with macular degeneration
