Alcohol consumption during pregnancy damages offspring's white matter - brain's connective network

One part of the prenatal brain that may be particularly sensitive to alcohol's effects is white matter, nerve fibers through which information is exchanged between different areas of the central nervous system.

How mirror neurons allow us to learn and socialize by going through the motions in the head

The old adage that we can only learn how to do something by trying it ourselves may have to be revised in the light of recent discoveries in neuroscience.

Miniature therapeutic ultrasound device

A prototype of a therapeutic ultrasound device, developed by a Cornell graduate student, fits in the palm of a hand, is battery-powered and packs enough punch to stabilize a gunshot wound or deliver drugs to brain cancer patients.

SRS microscopy helps track molecules and drugs in live cells

A new type of highly sensitive microscopy developed by researchers at Harvard University could greatly expand the limits of modern biomedical imaging, allowing scientists to track the location of minuscule metabolites and drugs in living cells and tissues without the use of any kind of fluorescent labeling.

New insight into the origin of face recognition in humans

Chimpanzees recognize their pals by using some of the same brain regions that switch on when humans register a familiar face, according to a report published online on December 18th in Current Biology, a Cell Press publication.

Evidence that Alzheimer's disease affects women differently than men

Nearly 4.5 million people suffer from Alzheimer's disease (AD) in our country, and more than half of them are women, according to the National Institute on Aging in Bethesda, Md.

New imaging technique allows simultaneous tracking of gene expression and movement

Flies expressing green fluorescent protein (GFP) in their retina cells or other tissues can be tracked by specially modified video cameras, creating a real time computer record of movement and gene expression.

Narrow-band imaging comparable to white light colonoscopy in differentiating colorectal polyps

Researchers from Yale University School of Medicine compared narrow-band imaging (NBI) without high magnification to standard white light colonoscopy in differentiating colorectal polyps during real-time colonoscopy and found that NBI was not more accurate than white light colonoscopy.

Computer-aided detection (CAD) mammography for breast cancer screening

Computer programs designed to help radiologists could identify more cases of breast cancer, but they might also increase the number of false-positive results, which can lead to biopsies in healthy women, according to a recent systematic review.

Single adult stem cell can self-renew in a mammal

The first demonstration that a single adult stem cell can self-renew in a mammal was reported at the American Society for Cell Biology (ASCB) 48th Annual Meeting, Dec. 13-17, 2008 in San Francisco.
