New understanding about mechanism for cell death after stroke leads to possible therapy 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. Contact: Melissa Ashman Public Release: 22-Nov-2009
New cancer target for non-Hodgkin's lymphoma Physician-scientists from Weill Cornell Medical College have discovered a molecular mechanism that may prove to be a powerful target for the treatment of non-Hodgkin's lymphoma, a type of cancer that affects lymphocytes, or white blood cells. By exploiting this mechanism, researchers have been able to powerfully suppress tumor formation in lab testing and in animal models. Contact: Andrew Klein Public Release: 22-Nov-2009
Cancer metabolism discovery uncovers new role of IDH1 gene mutation in brain cancer Agios Pharmaceuticals 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. The mutated form of IDH1 produces a metabolite, 2-hydroxyglutarate, which may contribute to the formation and malignant progression of gliomas, the most common type of brain cancers, through altered metabolic activity. This discovery appears to reverse the previously held belief that IDH1 was non functional for cancer-causing activity. Contact: Kathryn Morris Public Release: 22-Nov-2009
New hydrogen-storage method discovered Scientists at the Carnegie Institution have found for the first time that high pressure can be used to make a unique hydrogen-storage material. The discovery paves the way for a new approach to the hydrogen-storage problem. The researchers found that the normally nonreactive, noble gas xenon combines with molecular hydrogen under pressure to form a previously unknown solid with unusual bonding chemistry. The discovery debuts a new family of materials, which could boost hydrogen technologies. Contact: Maddury Somayazulu Public Release: 22-Nov-2009
Butterfly proboscis to sip cells A butterfly's proboscis looks like a straw -- long, slender and used for sipping -- but it works more like a paper towel, according to Konstantin Kornev of Clemson University. He hopes to borrow the tricks of this piece of insect anatomy to make small probes that can sample the fluid inside of cells. Contact: Jason Bardi Public Release: 22-Nov-2009
Robotic clam digs in mudflats To design a lightweight anchor that can dig itself in to hold small underwater submersibles, Anette Hosoi of MIT borrowed techniques from one of nature's best diggers -- the razor clam. Contact: Jason Bardi Public Release: 22-Nov-2009
Gene mismatch influences success of bone marrow transplants A commonly inherited gene deletion can increase the likelihood of immune complications following bone marrow transplantation, an international team of researchers reports in the November 22 advance online issue of Nature Genetics. When the gene, called UGT2B17, is missing from the donor's genome but present in the recipient's, transplants have a significantly greater risk of a serious side-effect known as graft-versus-host disease, in which immune cells from the donor attack tissues in the recipient.

Surface bacteria maintain skin's healthy balance On the skin's surface, bacteria are abundant, diverse and constant, but inflammation is undesirable. Research at the University of California, San Diego School of Medicine now shows that the normal bacteria living on the skin surface trigger a pathway that prevents excessive inflammation after injury.

Generating electricity from air flow A group of researchers at the City College of New York is developing a new way to generate power for planes and automobiles based on materials known as piezoelectrics, which convert the kinetic energy of motion into electricity. They will present their concept later this month at the 62nd Annual Meeting of the American Physical Society's (APS) Division of Fluid Dynamics will take place from Nov. 22-24 at the Minneapolis Convention Center.

Aquatic creatures mix ocean water Understanding mixing in the ocean is of fundamental importance to modeling climate change or predicting the effects of an El Niņo on our weather. Modern ocean models primarily incorporate the effects of winds and tides. However, they do not generally take into account the mixing generated by swimming animals.

Nuclear weapons: Predicting the unthinkable If a nuclear weapon were detonated in a metropolitan area, how large would the affected area be? Where should first responders first go? Contact: Jason Socrates Bardi Public Release: 20-Nov-2009
Smartphone app illuminates power consumption A new application for the Android smartphone shows users and software developers how much power their applications are consuming. PowerTutor was developed by doctoral students and professors at the University of Michigan. Contact: Nicole Casal Moore Public Release: 20-Nov-2009
Effect of real-time CPR feedback reported at resuscitation science symposium The Resuscitation Outcomes Consortium is the largest clinical research network to study prehospital treatments for cardiac arrest in the United States and Canada. ROC conducted the first randomized study to assess if real-time audio-feedback, during the EMS prehospital course of care, would improve clinical outcome. Results of the study were presented on November 15 during the Resuscitation Science Symposium 2009 program. Contact: Clare Hagerty Public Release: 20-Nov-2009
Saving the single cysteine: New antioxidant system found We've all read studies about the health benefits of having a life partner. The same thing is true at the molecular level, where amino acids known as cysteines are much more vulnerable to damage when single than when paired up with other cysteines.

High blood pressure easy to miss in children with kidney disease Spot blood pressure readings in children with chronic kidney disease often fail to detect hypertension -- even during doctor's office visits -- increasing a child's risk for serious heart problems, according to research from Johns Hopkins Children's Center and other institutions. A report of the findings appears online in the Journal of American Society of Nephrology. Contact: Ekaterina Pesheva Public Release: 20-Nov-2009
It's a gas: New discovery may lead to heartier, high-yielding plants In a research report in the November 2009 journal Genetics, scientists show how a family of genes (1-aminocyclopropane-1-carboxylate synthase, or ACS genes), in the weed Arabidopsis thaliana, are responsible for production of ethylene. This gas affects many aspects of plant development, and this information, which will be applicable to other plants, lays the foundation for future genetic manipulation that could make plants disease resistant, able to survive and thrive in difficult terrain, and increase yields.

Older problem drinkers use more alcohol than do their younger counterparts Older adults who have alcohol dependence problems drink significantly more than do younger adults who have similar problems, a new study has found. The findings suggest that older problem drinkers may have developed a tolerance for alcohol and need to drink even more than younger abusers to achieve the effects they seek.
