Physicist's Tool Has Potential for Brain Mapping
May 16, 2013 — Physicists are developing a new tool that uses low-energy near-infrared light and fiber optics for optogenetic stimulation of cells. He believes it will be a useful tool for mapping physical and ... > full story -
Target to Prevent Hardening of Arteries Identified
May 16, 2013 — The gene Dkk1 encodes a protein that plays a key role in increasing the population of connective-tissue cells during wound repair, but prolonged Dkk1 signaling in cells lining blood vessels can lead ... > full story -
Gene Involved in Neurodegeneration Keeps Clock Running: Scientists Identify Another Gene Important to Morning Wake-Up Call
May 16, 2013 — Scientists have shown a gene involved in neurodegenerative disease also plays a critical role in the proper function of the circadian clock. In a study of the common fruit fly, the researchers found ... > full story -
Accelerated Aging in Children: Promising Treatment for Progeria Within Reach
May 16, 2013 — Pharmaceuticals that inhibit a specific enzyme may be useful in treating progeria, or accelerated aging in children. A new study indicates that the development of progeria in mice was inhibited upon ... > full story -
DNA-Guided Assembly Yields Novel Ribbon-Like Nanostructures
May 16, 2013 — DNA "linker" strands coax nano-sized rods to line up in way unlike any other spontaneous arrangement of rod-shaped objects. The arrangement -- with the rods forming "rungs" on ladder-like ribbons -- ... > full story -
Stem-Cell-Based Strategy Boosts Immune System in Mice
May 16, 2013 — Raising hopes for cell-based therapies, researchers have created the first functioning human thymus tissue from embryonic stem cells in the laboratory. The researchers showed that, in mice, the ... > full story -
Study Brings Greater Understanding of Tumor Growth Mechanism
May 16, 2013 — A new study has for the first time revealed how the loss of a particular tumor suppressing protein leads to the abnormal growth of tumors of the brain and nervous ... > full story -
Vicious Cycle: Obesity Sustained by Changes in Brain Biochemistry
May 16, 2013 — Scientists have shown that in the brain cells of rats, obesity impedes the production of a hormone that curbs appetite and inspires calorie burning. The root cause appears to be a breakdown in the ... > full story -
Genetic Risk for Schizophrenia Is Connected to Reduced IQ
May 16, 2013 — The relationship between the heritable risk for schizophrenia and low intelligence (IQ) has not been clear. Schizophrenia is commonly associated with cognitive impairments that may cause functional ... > full story -
First Prospective Trial Shows Molecular Profiling Timely for Tailoring Therapy
May 15, 2013 — CUSTOM is the first completed prospective clinical trial that used genetic analysis alone to assign cancer treatment for patients with one of three different cancers. Findings suggest patients, and ... > full story
