Electronic health records slow the rise of healthcare costs Posted: 15 Jul 2013 05:24 PM PDT Use of electronic health records can reduce the costs of outpatient care by roughly 3 percent, compared to relying on traditional paper records.

New insights on cancer cell signaling Posted: 15 Jul 2013 01:49 PM PDT A pair of studies sheds light on a biological process which is activated across a vast range of malignancies.

Fear factor: Missing brain enzyme leads to abnormal levels of fear in mice, new research reveals Posted: 15 Jul 2013 01:48 PM PDT A little bit of learned fear is a good thing, keeping us from making risky, stupid decisions or falling over and over again into the same trap. But new research from neuroscientists and molecular biologists shows that a missing brain protein may be the culprit in cases of severe over-worry, where the fear perseveres even when there's nothing of which to be afraid.

Music decreases perceived pain for kids in pediatric ER Posted: 15 Jul 2013 01:48 PM PDT Medical researches have provided more evidence that music decreases children's perceived sense of pain.

Researchers generate long-lasting blood vessels from reprogrammed human cells Posted: 15 Jul 2013 01:48 PM PDT Researchers have used vascular precursor cells derived from human induced pluripotent stem cells to generate, in an animal model, functional blood vessels that lasted as long as nine months.

Elevated blood pressure increasing among children, adolescents Posted: 15 Jul 2013 01:47 PM PDT The risk of elevated blood pressure among children and adolescents rose 27 percent during a 13-year period, according to new research. Higher body mass, larger waistlines and eating excess sodium may be the reasons for the elevated blood pressure readings, researchers said.

Chinese people may be at higher risk for stroke than Caucasians Posted: 15 Jul 2013 01:47 PM PDT A new study suggests that Chinese people may be at higher risk for stroke than Caucasians.

Common autism supplement affects endocrine system Posted: 15 Jul 2013 12:11 PM PDT Plant-based diets are healthy. Plants are high in flavonoids. So flavonoids are healthy. At least that's the reasoning of many manufacturers of flavonoid-based nutritional supplements. But a new study shows that may not be the case. Flavonoids tested in the study affected the endocrine system in ways that in one case promoted cancer and in another repressed it.

Chemical compound shows promise as alternative to opioid pain relievers Posted: 15 Jul 2013 12:11 PM PDT A drug targeting a protein complex containing two different types of opioid receptors may be an effective alternative to morphine and other opioid pain medications, without any of the side effects or risk of dependence, according to new research.

CSI-style DNA fingerprinting tracks down cause of cancer spread Posted: 15 Jul 2013 12:11 PM PDT How do stationary cancer cells get the mutations that allow them to travel through the body to seed metastasis? Do they just grow these mutations themselves? Study shows that cancer cells fuse with blood cells -- which already can travel! -- to create a hybrid, metastatic cancer cell.

Comprehensive list of gene variants developed for cancer cells from nine tissue types Posted: 15 Jul 2013 12:11 PM PDT Scientists have developed a comprehensive list of genetic variants for each of the types of cells that comprise what is known as the NCI-60 cell line collection. This new list adds depth to the most frequently studied human tumor cell lines in cancer research, molecular pharmacology, and drug discovery.

In children with fever, researchers distinguish bacterial from viral infections Posted: 15 Jul 2013 12:10 PM PDT Many children develop fevers without an obvious cause. Now, researchers have shown they can tell whether a child has a viral or bacterial infection by profiling the activity of genes in a blood sample.

Scientists construct visual of intracellular 'zip code' signaling linked to learning, memory Posted: 15 Jul 2013 11:18 AM PDT New research provides a rare "picture" of the activity taking place at the single molecular level: visual evidence of the mechanisms involved when a cell transports mRNA (or messenger RNA) to where a protein is needed to perform a cellular function.

Lunar cycle affects cardiac patients undergoing acute aortic dissection: Waning and full moon cycles impact length of stay, mortality Posted: 15 Jul 2013 11:18 AM PDT If you need cardiac surgery in the future, aortic dissection in particular, reach for the moon. Or at least try to schedule your surgery around its cycle. A new study found that acute aortic dissection repair performed in the waning full moon appears to reduce the odds of death, and a full moon was associated with shorter length of stay.

Chew more to retain more energy Posted: 15 Jul 2013 10:46 AM PDT Almonds may still be considered one of the highest energy food sources but it's not about how much you bite off, instead it's about how much you chew, according to new research.

Spicing up food can make up for missing fat Posted: 15 Jul 2013 10:46 AM PDT Adding just a small amount of everyday herbs and spices to vegetables and reduced-calorie meals may make those foods more appetizing to consumers, which could ultimately help Americans cut down on dietary fat and choose more foods in line with the Dietary Guidelines for Americans.

Solving DNA puzzles is overwhelming computer systems, researchers warn Posted: 15 Jul 2013 08:46 AM PDT Scientists in the fast-growing field of computational genomics are getting lots of data but lack the computer power needed to analyze it quickly.

How cranberries impact infection-causing bacteria Posted: 15 Jul 2013 08:46 AM PDT Researchers are shedding light on the biological mechanisms by which cranberries may impart protective properties against urinary tract and other infections.

Brain discovery could help schizophrenics Posted: 15 Jul 2013 07:56 AM PDT The discovery of brain impairment in mice may eventually lead to better therapies for people with schizophrenia and major depression.

Path of plaque buildup in brain shows promise as early biomarker for Alzheimer's disease Posted: 15 Jul 2013 07:51 AM PDT The trajectory of amyloid plaque buildup —- clumps of abnormal proteins in the brain linked to Alzheimer's disease —- may serve as a more powerful biomarker for early detection of cognitive decline rather than using the total amount to gauge risk, researchers suggest in a new study.

Neural origins of hot flashes identified in menopausal women Posted: 15 Jul 2013 07:51 AM PDT A new study from neuroscientists provides the first novel insights into the neural origins of hot flashes in menopausal women in years. The study may inform and eventually lead to new treatments for those who experience the sudden but temporary episodes of body warmth, flushing and sweating.

Drug shows dramatic reduction in seizures in patients with tuberous sclerosis complex Posted: 15 Jul 2013 07:51 AM PDT A drug originally developed to prevent the rejection of transplanted organs has now been shown to dramatically reduce seizures in patients with tuberous sclerosis complex (TSC) -- a genetic disease characterized by benign tumors on multiple organ systems. TSC is estimated to affect more than a million individuals throughout the world.

Cancer researchers discover how BRCA mutation starts breast, ovarian cancers Posted: 15 Jul 2013 07:51 AM PDT Scientists have solved a key piece in the puzzle of how BRCA1 gene mutations specifically predispose women to breast and ovarian cancers.

Surprise finding reveals how adaptive our immune systems can be Posted: 15 Jul 2013 06:12 AM PDT Studies of patients with immunodeficiencies involving single gene mutations can reveal a great deal about our immune systems, especially when actual symptoms do not accord with clinical expectations. Australian scientists acknowledge such a gap between expectation and reality in a new study, which examines people with "Autosomal Dominant Hyper IgE Syndrome."

Black-legged ticks linked to encephalitis in New York state Posted: 15 Jul 2013 06:12 AM PDT The number of tick-borne illnesses reported to the U.S. Centers for Disease Control and Prevention is on the rise. Lyme disease leads the pack, with some 35,000 cases reported annually. In the Northeast, the black-legged ticks that spread Lyme disease also infect people with other maladies, among them anaplasmosis, babesiosis, and -- now -- Powassan encephalitis.

Findings offer alternative approach to creating a universal influenza vaccine Posted: 15 Jul 2013 06:12 AM PDT Scientists have determined that it might be possible to stimulate the immune system against multiple strains of influenza virus by sequentially vaccinating individuals with distinct influenza strains isolated over the last century. It represents a different approach to creating a "universal" flu vaccine. Their results also suggest that world health experts might need to re-evaluate standard tests used for surveillance of novel influenza strains.

Physicists offer novel insight into experimental cancer treatment Posted: 15 Jul 2013 04:03 AM PDT Physicists have carried out new research into how the heating effect of an experimental cancer treatment works.

Very preterm babies show bonding difficulties despite parental sensitivity Posted: 15 Jul 2013 04:03 AM PDT A new study suggests that some very preterm babies have trouble bonding with their care-givers due to neurological impairments and not to the way their parents interact with them.
