Ionic liquid improves speed and efficiency of hydrogen-producing catalyst Posted: 16 Jun 2012 11:55 AM PDT The design of a nature-inspired material that can make energy-storing hydrogen gas has gone holistic. Usually, tweaking the design of this particular catalyst -- a work in progress for cheaper, better fuel cells -- results in either faster or more energy efficient production but not both. Now, researchers have found a condition that creates hydrogen faster without a loss in efficiency.

Natural antioxidant can protect against cardiovascular disease Posted: 16 Jun 2012 11:55 AM PDT Researchers have discovered an enzyme that, when found at high levels and alongside low levels of HDL (good cholesterol), can dramatically reduce the risk of cardiovascular disease.

Freud's theory of unconscious conflict linked to anxiety symptoms Posted: 16 Jun 2012 11:55 AM PDT An experiment that Sigmund Freud could never have imagined 100 years ago may help lend scientific support for one of his key theories, and help connect it with current neuroscience.

Low-dose vitamin D may not prevent fractures in healthy women –- what about higher doses? Posted: 16 Jun 2012 11:54 AM PDT Vitamin D and calcium are dietary requirements, but it's unclear how much is best for us. New draft findings conclude that for healthy, postmenopausal women, daily supplementation with low levels of vitamin D — up to 400 international units — combined with 1,000 milligrams of calcium, does not reduce fracture risk.

California physicians unprepared for electronic health record regulations Posted: 16 Jun 2012 11:54 AM PDT Electronic health records (EHRs) are used widely by California physicians, but many of their systems are not designed to meet new federal standards aimed at improving the quality of health care, according to a new report.

Inexpensive approach to preventing type 2 diabetes shows promise Posted: 16 Jun 2012 11:54 AM PDT A simple, inexpensive method for preventing type 2 diabetes that relies on calling people and educating them on the sort of lifestyle changes they could make to avoid developing the disease has proven effective in a study conducted by researchers.

Nanoparticles hold promise to improve blood cancer treatment Posted: 15 Jun 2012 05:47 PM PDT Researchers have engineered nanoparticles that show great promise for the treatment of multiple myeloma (MM), an incurable cancer of the plasma cells in bone marrow.

Answer isn't always on the 'tip of the tongue' for older adults Posted: 15 Jun 2012 05:47 PM PDT Has your memory failed you today, such as struggling to recall a word that's "on the tip of your tongue?" If so, you're not alone.

Graduated driving laws reduce teen drunk driving Posted: 15 Jun 2012 05:47 PM PDT State laws that limit driving privileges for teens have reduced the incidence of drinking and driving among the nation's youngest licensees, according to a new study. The vast majority of states now have laws that limit teen driving privileges and impose stiff penalties for driving under the influence.

Smoking-cessation 'quitlines' could help identify hazardous drinkers Posted: 15 Jun 2012 05:47 PM PDT Few if any smoking-cessation "quitlines" routinely screen and counsel callers about their alcohol use. A new study has examined drinking patterns among smokers calling the New York State Smokers' Quitline. Smokers calling the quitline who reported a hazardous drinking pattern also had lower smoking-cessation rates. Quitlines could potentially identify hazardous drinkers and perhaps provide brief alcohol interventions.

Researchers find a strong association between alcohol dependence and chromosome 5q13.2 Posted: 15 Jun 2012 05:47 PM PDT There is a strong genetic influence on the risk of developing alcohol dependence (AD). Copy number variations (CNVs) refer to a class of genetic variation that can delete and duplicate whole genes, leading to powerful genetic effects. A first-of-its-kind study has found a significant association between AD and CNVs on chromosome 5q13.2.

Scientists tie DNA repair to key cell signaling network Posted: 15 Jun 2012 11:17 AM PDT Researchers have found a surprising connection between a key DNA-repair process and a cellular signaling network linked to aging, heart disease, cancer and other chronic conditions.

Antioxidant shown to reduce blindness risk in extremely premature babies Posted: 15 Jun 2012 07:43 AM PDT A new study suggests that the antioxidant, rhSOD (recombinant human Cu/Zn superoxide dismutase), reduces the risk of developing ROP in extremely low gestational age newborns.

Musical brain patterns could help predict epileptic seizures Posted: 15 Jun 2012 07:39 AM PDT New insights into the electrical patterns of the brain reveal how brain waves with rapidly increasing frequencies, like musical 'glissandi,' could help predict when a patient is going to start an epileptic seizure.

Quantum computing? Quantum bar magnets in a transparent salt Posted: 15 Jun 2012 07:39 AM PDT Scientists have managed to switch on and off the magnetism of a new material using quantum mechanics, making the material a test bed for future quantum devices.

New finding on nerve repair Posted: 15 Jun 2012 07:39 AM PDT Researchers have furthered understanding of the mechanism by which the cells that insulate the nerve cells in the peripheral nervous system, Schwann cells, protect and repair damage caused by trauma and disease.
