How elderly go from being perceived as capable consumer to 'old person' Posted: 12 Nov 2012 02:14 PM PST Many baby boomers want to improve the way people view aging, but a researcher has found they often reinforce negative stereotypes of old age when interacting with their own parents, coloring the way those seniors experience their twilight years.

Smoking parents often expose children to tobacco smoke in their cars Posted: 12 Nov 2012 02:14 PM PST A new study suggests that parents may not recognize the dangers of smoking in their cars with a child present.

Divorce costs thousands of American women health insurance coverage Posted: 12 Nov 2012 02:14 PM PST About 115,000 American women lose private health insurance every year in the wake of divorce, a study shows.

Snap judgments during speed dating Posted: 12 Nov 2012 02:13 PM PST For speed daters, first impressions are everything. But it's more than just whether someone is hot or not. Researchershave found that people make such speed-dating decisions based on a combination of two different factors that are related to activity in two distinct parts of the brain.

Jellyfish-inspired device that captures cancer cells from blood samples could enable better patient monitoring Posted: 12 Nov 2012 02:13 PM PST Tumor cells circulating in a patient's bloodstream can yield a great deal of information on how a tumor is responding to treatment and what drugs might be more effective against it. But first, these rare cells have to be captured and isolated from the many other cells found in a blood sample. Scientists are now working on microfluidic devices that can isolate circulating tumor cells.

L-DOPA therapy for Angelman syndrome may have both benefits and unanticipated effects, study suggests Posted: 12 Nov 2012 02:12 PM PST New research from the University of North Carolina provides a neurological justification for this therapeutic approach, but researchers caution there could be unanticipated effects.

Head injury and pesticide exposure leads to triple the risk of Parkinson’s disease Posted: 12 Nov 2012 02:10 PM PST A new study shows that people who have had a head injury and have lived or worked near areas where the pesticide paraquat was used may be three times more likely to develop Parkinson's disease.

Cilia guide neuronal migration in developing brain Posted: 12 Nov 2012 12:03 PM PST A new study demonstrates the dynamic role cilia play in guiding the migration of neurons in the embryonic brain. Cilia are tiny hair-like structures on the surfaces of cells, but here they are acting more like radio antennae. In developing mouse embryos, researchers were able to see cilia extending and retracting as neurons migrate. The cilia appear to be receiving signals needed for neurons to find their places.

Meditation appears to produce enduring changes in emotional processing in the brain Posted: 12 Nov 2012 12:03 PM PST A new study has found that participating in an eight-week meditation training program can have measurable effects on how the brain functions even when someone is not actively meditating. The researchers also found differences in those effects based on the specific type of meditation practiced.

Infants mimic unusual behavior when accompanied by language Posted: 12 Nov 2012 10:56 AM PST A new study shows the power of language in infants' ability to understand the intentions of others. The results, based on two experiments, show that introducing a novel word for the impending novel event had a powerful effect on the infants' tendency to imitate the behavior. Infants were more likely to imitate behavior, however unconventional, if it had been named, than if it remained unnamed, the study shows.

Genetic link between pancreatitis and alcohol consumption Posted: 12 Nov 2012 10:55 AM PST A new study reveals a genetic link between chronic pancreatitis and alcohol consumption. Researchers found a genetic variant on chromosome X near the claudin-2 gene (CLDN2) that predicts which men who are heavy drinkers are at high risk of developing chronic pancreatitis.

Humans are slowly but surely losing intellectual and emotional abilities, article suggests Posted: 12 Nov 2012 10:55 AM PST Human intelligence and behavior require optimal functioning of a large number of genes, which requires enormous evolutionary pressures to maintain. A provocative theory suggests that we are losing our intellectual and emotional capabilities because the intricate web of genes endowing us with our brain power is particularly susceptible to mutations and that these mutations are not being selected against in our modern society.

List of diseases spread by deer tick grows, including malaria-like problems and potentially fatal encephalitis Posted: 12 Nov 2012 10:55 AM PST An emerging tick-borne disease that causes symptoms similar to malaria is expanding its range in areas of the northeast where it has become well-established, according to new research.

Gene sequencing project identifies abnormal gene that launches rare childhood leukemia Posted: 12 Nov 2012 10:52 AM PST Research has identified a fusion gene responsible for almost 30 percent of a rare subtype of childhood leukemia with an extremely poor prognosis. The finding offers the first evidence of a mistake that gives rise to a significant percentage of acute megakaryoblastic leukemia (AMKL) cases in children. AMKL accounts for about 10 percent of pediatric acute myeloid leukemia (AML). The discovery paves the way for desperately needed treatment advances.

Genome sequencing of Burkitt Lymphoma reveals unique mutation Posted: 12 Nov 2012 08:31 AM PST In the first broad genetic landscape mapped of a Burkitt lymphoma tumor, scientists identified 70 mutations, including several that had not previously been associated with cancer and a new one that was unique to the disease.

New live vaccine approach for SARS and novel coronaviruses discovered Posted: 12 Nov 2012 08:31 AM PST Researchers have found that accelerating the rate of mutations in the coronavirus responsible for deadly severe acute respiratory syndrome cripples the virus's ability to cause disease in animals.

Smart drug improves survival in older patients with acute myeloid leukemia Posted: 12 Nov 2012 08:31 AM PST A new study has found acute myeloid leukemia (AML) patients given a new type of 'smart drug' in addition to chemotherapy treatment are 22 per cent less likely to relapse and around 13 per cent less likely to die from their disease.

Bringing measuring accuracy to radical treatment Posted: 12 Nov 2012 07:14 AM PST An international team of scientists has determined for the first time the absolute density of active substances called radicals found in a state of matter known as plasma, in a new study. These findings could have important implications for medicine -- for example, for stimulating tissue regeneration, or to induce a targeted antiseptic effect in vivo without affecting neighboring tissues.

Call for global monitoring of infectious diseases in dogs and cats Posted: 12 Nov 2012 07:10 AM PST Most emerging infectious diseases of humans come from animals. International health agencies monitor these diseases, but they do so only for humans and livestock, not for companion dogs and cats. A new study recommends a global system is needed to monitor infectious diseases of companion dogs and cats.

Genetic defense mechanism may offer biological clue to racial disparities in kidney disease Posted: 12 Nov 2012 06:59 AM PST Genetic changes that protected their ancestors against fly-borne parasites may partly explain why African-Americans with lupus are up to five times more likely to develop end-stage kidney disease than those of European descent.

Combination of PI3-kinase and PARP inhibitors may offer new treatment option for triple-negative breast cancers Posted: 12 Nov 2012 06:59 AM PST The simultaneous inhibition of two separate and seemingly unrelated pathways could potentially provide an effective treatment for women with triple-negative breast cancer, according to results of two new studies.

Did wild birds cause the 2010 deadly West Nile virus outbreak in Greece? Posted: 12 Nov 2012 06:05 AM PST In 2010, 35 people in Greece died from a West Nile virus (WNV) outbreak, with a further 262 laboratory-confirmed human cases. A new article examines whether wild or migratory birds could have been responsible for importing and amplifying the deadly virus.

How bacteria attack their host cells with sticky lollipops Posted: 12 Nov 2012 06:05 AM PST Yersinia enterocolitica, a pathogenic bacterium, causes fever and diarrhea. With the help of a protein anchored in its membrane, Yersinia attaches to its host cells and infects them. Scientists have determined the structure of an important component of the membrane protein and have gained insight into its biogenesis. The membrane proteins provide an interesting starting point for the development of new antibiotics against pathogens.

Helmets save lives of skiers and snowboarders, study suggests Posted: 12 Nov 2012 05:49 AM PST The use of helmets by skiers and snowboarders decreases the risk and severity of head injuries and saves lives, new research suggests. The findings debunk long-held beliefs by some that the use of helmets gives athletes a false sense of security and promotes dangerous behavior that might increase injuries.
