Researchers have identified a group of traders consistently able to outperform the market, even during the credit crisis. The study by John Coates and Lionel Page of the University of Cambridge offers a rare glimpse into how biology, experience and compensation schemes work together to make a profitable and – crucially – a prudent risk taker.

By playing the video game Rock Band for an hour, Kansas State University students were able to help a pair of psychology professors with their research to understand how people can achieve flow while at work or while performing skilled tasks.
Clive Fullagar, a professor, and Patrick Knight, an associate professor, found that -- like Goldilocks -- most people achieve flow with work that is neither too easy nor too hard but just right.
Stents that keep weakened and flabby arteries from collapsing have been true life-savers. But after six months, those stents are no longer needed -- once the arteries are strengthened, they become unnecessary. Previously, doctors had no choice but to leave them in place.
Prof. Meital Zilberman of Tel Aviv University's Department of Biomedical Engineering has developed a new patent-pending fiber platform that carries drugs where they're needed, then dissolves.
Universitat Autònoma de Barcelona (UAB) researchers have confirmed that a diet rich in polyphenols and polyunsaturated fatty acids, patented as an LMN diet, helps boost the production of the brain's stem cells -neurogenesis- and strengthens their differentiation in different types of neuron cells. The research revealed that mice fed an LMN diet, when compared to those fed a control diet, have more cell proliferation in the two areas of the brain where neurogenesis is produced, the olfactory bulb and the hippocampus, both of which are greatly damaged in patients with Alzheimer's disease.
People with Multiple Sclerosis (MS) feel more than twice as much withheld anger as the general population and this could have an adverse effect on their relationships and health, according to a study published in the December issue of the European Journal of Neurology.
Italian researchers assessed 195 patients with MS, using a range of scales that measure anger, depression and anxiety, and then compared them with the general population.
Outrageous prices may not be the only thing causing anger at the petrol pumps. A new study, published in the open access journal BMC Physiology, has shown that rats exposed to fumes from leaded and unleaded gasoline become more aggressive.
Farmington, CT – Current research suggests that a common oral bacterium may exacerbate autoimmune disease. The related report by Nichols et al, "Unique Lipids from a Common Human Bacterium Represent a New Class of TLR2 Ligands Capable of Enhancing Autoimmunity," appears in the December 2009 issue of The American Journal of Pathology.
Evidence of cardiovascular risks associated with taking Vioxx, the popular, nonsteroidal anti-inflammatory drug (rofecoxib), could have been identified nearly four years before its manufacturer, Merck & Co. Inc., voluntarily pulled the drug from the market.
Alzheimer's disease is caused by the build-up of a brain peptide called amyloid-beta. That's why eliminating the protein has been the focus of almost all drug research pursuing a cure for the devastating neurodegenerative condition.
But that may be counterproductive, says Dr. Inna Slutsky of Tel Aviv University's Department of Physiology and Pharmacology, Sackler Faculty of Medicine. Her recent research demonstrates that amyloid-beta is also necessary to maintain proper brain functioning.
These findings may shake the foundations of Alzheimer's research.
Women who store fat on their waist in middle age are more than twice as likely to develop dementia when they get older, reveals a new study from the Sahlgrenska Academy.
The study has just been published in the scientific journal Neurology.
"Anyone carrying a lot of fat around the middle is at greater risk of dying prematurely due to a heart attack or stroke," says Deborah Gustafson, senior lecturer at the Sahlgrenska Academy. "If they nevertheless manage to live beyond 70, they run a greater risk of dementia."
The generation of new nerve cells in the brain is regulated by a peptide known as C3a, which directly affects the stem cells' maturation into nerve cells and is also important for the migration of new nerve cells through the brain tissue, reveals new research from the Sahlgrenska Academy published in the journal Stem Cells.
Although the research has been carried out using mice and cultured cells, it could lead to a new medicine for human beings, which could be given to patients who have had a stroke or other disorders that damage or destroy the nerve cells.
Cambridge, MA – November 23, 2009 – Agios Pharmaceuticals today announced that its scientists have established, for the first time, that the mutated IDH1 gene has a novel enzyme activity consistent with a cancer-causing gene, or oncogene. This breakthrough discovery shows that the mutated form of IDH1 produces a metabolite, 2-hydroxyglutarate (2HG), which may contribute to the formation and malignant progression of gliomas, the most common type of brain cancers. This discovery appears to reverse the previously held belief that IDH1 was non functional for cancer-causing activity.
Scientists at the Brain Research Centre, a partnership of the University of British Columbia Faculty of Medicine and Vancouver Coastal Health Research Institute, have uncovered new information about the mechanism by which brain cells die following a stroke, as well as a possible way to mitigate that damage. The results of the study were recently published online in Nature Medicine.
Treatment that includes medication plus a structured training program for parents reduces serious behavioral problems in children with autism and related conditions, according to a study funded by the National Institute of Mental Health (NIMH). The study, which was part of the NIMH Research Units on Pediatric Psychopharmacology (RUPP) Autism Network, was published in the December 2009 issue of the Journal of the American Academy of Child and Adolescent Psychiatry.
Long durations of exposure to formaldehyde used for embalming in the funeral industry were associated with an increased risk of death from myeloid leukemia, according to a new study published online November 20 in the Journal of the National Cancer Institute.
Previous studies have shown excess mortality from lymphohematopoietic malignancies and brain cancer in anatomists, pathologists, and funeral industry workers, all of whom may have worked with formaldehyde.
