| New gene variant may explain psychotic features in bipolar disorder Posted: 07 Mar 2013 07:43 AM PST Researchers at Karolinska Institutet have found an explanation for why the level of kynurenic acid (KYNA) is higher in the brains of people with schizophrenia or bipolar disease with psychosis. The study, which is published in the scientific periodical Molecular Psychiatry, identifies a gene variant associated with an increased production of KYNA. |
| Circuitry of cells involved in immunity, autoimmune diseases exposed Posted: 06 Mar 2013 12:50 PM PST New work from the Broad Institute’s Klarman Cell Observatory, Brigham and Women’s Hospital, Harvard University, MIT, and Yale University expands the understanding of how one type of immune cell – known as a T helper 17 or Th17 cell – develops, and how its growth influences the development of immune responses. By figuring out how these cells are “wired,” the researchers make a surprising connection between autoimmunity and salt consumption, highlighting the interplay of genetics and environmental factors in disease susceptibility. |
| How the Body's Energy Molecule Transmits Three Types of Taste to the Brain Posted: 06 Mar 2013 12:32 PM PST Saying that the sense of taste is complicated is an understatement, that it is little understood, even more so. Exactly how cells transmit taste information to the brain for three out of the five primary taste types was pretty much a mystery, until now. |
| Mom’s Placenta Reflects Her Exposure to Stress, Penn Vet Team Finds Posted: 06 Mar 2013 12:23 PM PST The mammalian placenta is more than just a filter through which nutrition and oxygen are passed from a mother to her unborn child. According to a new study by a research group from the University of Pennsylvania School of Veterinary Medicine, if a mother is exposed to stress during pregnancy, her placenta translates that experience to her fetus by altering levels of a protein that affects the developing brains of male and female offspring differently. |
| New clues to causes of peripheral nerve damage Posted: 06 Mar 2013 09:31 AM PST Anyone whose hand or foot has “fallen asleep” has an idea of the numbness and tingling often experienced by people with peripheral nerve damage. The condition also can cause a range of other symptoms, including unrelenting pain, stinging, burning, itching and sensitivity to touch. |
| Temp-Controlled 'Nanopores' May Allow Detailed Blood Analysis Posted: 06 Mar 2013 09:10 AM PST Tiny biomolecular chambers called nanopores that can be selectively heated may help doctors diagnose disease more effectively if recent research by a team at the National Institute of Standards and Technology (NIST), Wheaton College, and Virginia Commonwealth University (VCU) proves effective. Though the findings may be years away from application in the clinic, they may one day improve doctors' ability to search the bloodstream quickly for indicators of disease—a longstanding goal of medical research. |
| How to predict the progress of technology Posted: 06 Mar 2013 08:08 AM PST Researchers at MIT and the Santa Fe Institute have found that some widely used formulas for predicting how rapidly technology will advance — notably, Moore’s Law and Wright’s Law — offer superior approximations of the pace of technological progress. The new research is the first to directly compare the different approaches in a quantitative way, using an extensive database of past performance from many different industries. |
