Research breakthrough selectively represses the immune system
Innovative biotechnology selectively inhibits the part of the immune system responsible for attacking myelin and gives new hope to those suffering from autoimmune diseases such as Multiple Sclerosis, type 1 diabetes, food allergies, and asthma.

Daycare has many benefits for children, but researchers find mysterious link with overweight
Young children who attend daycare on a regular basis are 50 percent more likely to be overweight compared to those who stayed at home with their parents, according to a study by researchers at the University of Montreal and the CHU Sainte-Justine Hospital Research Centre.

Stanford/Yale study gives insight into subtle genomic differences among our own cells
Stanford University School of Medicine scientists have demonstrated, in a study conducted jointly with researchers at Yale University, that induced pluripotent stem cells -- the embryonic-stem-cell lookalikes whose discovery a few years ago won this year's Nobel Prize in medicine -- are not as genetically unstable as was thought.

International team discovers likely basis of birth defect causing premature skull closure in infants
An international team of geneticists, pediatricians, surgeons and epidemiologists from 23 institutions across three continents has identified two areas of the human genome associated with the most common form of non-syndromic craniosynostosis -- premature closure of the bony plates of the skull.

Skin cells reveal DNA's genetic mosaic
The prevailing wisdom has been that every cell in the body contains identical DNA.

Breakthrough nanoparticle halts multiple sclerosis
In a breakthrough for nanotechnology and multiple sclerosis (MS), a biodegradable nanoparticle delivers an antigen that tricks the immune system and halts MS in mice.

Optogenetics illuminates pathways of motivation through brain, Stanford study shows
Karl Deisseroth, M.D., Ph.D., a professor of bioengineering and of psychiatry and behavioral sciences at Stanford University, and postdoctoral scholar Melissa Warden, Ph.D., describe how they have isolated the neurons that carry split-second decisions to act from the higher brain to the brain stem.

A better thought-controlled computer cursor
Stanford researchers have designed the fastest, most accurate algorithm yet for brain-implantable prosthetic systems that can help disabled people maneuver computer cursors with their thoughts.

Fabrication on patterned silicon carbide produces bandgap to advance graphene electronics
By fabricating graphene structures atop nanometer-scale

Gerontologists say research and data should drive policy, budget decisions
America's top authorities on aging spent the last week at the Gerontological Society of America's Annual Scientific Meeting in San Diego detailing workable solutions to the challenges presented by a rapidly aging population, including the demand for affordable health care, high rates of disease, and retirement security.
