Analysis finds likely U.S. voters rank health care second most important issue in presidential choice Posted: 10 Oct 2012 02:22 PM PDT A new analysis of 37 national opinion polls conducted by 17 survey organizations finds that health care is the second most important issue for likely voters in deciding their 2012 presidential vote. This is the highest that health care has been ranked as a presidential election issue since 1992.

Testosterone increases honesty, study suggests Posted: 10 Oct 2012 02:22 PM PDT Testosterone is considered the most important male hormone, associated with aggression and posturing. Researchers have now been able to demonstrate that this sex hormone surprisingly also fosters social behavior. In play situations, subjects who had received testosterone clearly lied less frequently than individuals who had only received a placebo.

First whole genome sequencing of multiple pancreatic cancer patients has been outlined Posted: 10 Oct 2012 02:21 PM PDT Whole genome sequencing -- spelling all 3 billion letters in the human genome -- "is an obvious and powerful method for advancing our understanding of pancreatic cancer," according to a new study.

Singing mice show signs of learning Posted: 10 Oct 2012 02:21 PM PDT Guys who imitate Luciano Pavarotti or Justin Bieber to get the girls aren't alone. Male mice may do a similar trick, matching the pitch of other males' ultrasonic serenades. The mice also have certain brain features, somewhat similar to humans and song-learning birds, which they may use to change their sounds, according to a new study.

Negative news stories affect women's stress levels but not men's Posted: 10 Oct 2012 02:21 PM PDT Bad news articles in the media increase women's sensitivity to stressful situations, but do not have a similar effect on men, according to a new study.

Nerve and muscle activity vary across menstrual cycle Posted: 10 Oct 2012 02:19 PM PDT Nerve fibers, and the muscles they control, behave differently at different points along the menstrual cycle, potentially making women more vulnerable to knee injuries.

High Levels of Blood-Based Protein Specific to Mesothelioma Posted: 10 Oct 2012 02:19 PM PDT Researchers have discovered the protein product of a little-known gene may one day prove useful in identifying and monitoring the development of mesothelioma in early stages, when aggressive treatment can have an impact on the progression of disease and patient prognosis.

Older adults tend not to stick with their meds following heart attacks Posted: 10 Oct 2012 02:19 PM PDT A new study of Medicare patients after heart attacks revealed an overall low exposure to the four medication classes.

Exercise could fortify immune system against future cancers Posted: 10 Oct 2012 01:18 PM PDT A small pilot study suggests that T cells become more responsive in exercising cancer survivors weeks after chemo ends.

Minutes of hard exercise can lead to all-day calorie burn Posted: 10 Oct 2012 01:18 PM PDT Time spent in the drudgery of strenuous exercise is a well-documented turn-off for many people who want to get in better shape. In a new study, researchers show that exercisers can burn as many as 200 extra calories in as little as 2.5 minutes of concentrated effort a day -- as long as they intersperse longer periods of easy recovery in a practice known as sprint interval training.

Scientists pinpoint gene variations linked to higher risk of bipolar disorder Posted: 10 Oct 2012 12:14 PM PDT Scientists have identified small variations in a number of genes that are closely linked to an increased risk of bipolar disorder, a mental illness that affects nearly six million Americans.

Neuroimaging technique captures cocaine's devastating effect on brain blood flow Posted: 10 Oct 2012 12:12 PM PDT Researchers have developed a high-resolution, 3D optical Doppler imaging tomography technique that captures the effects of cocaine restricting the blood supply in vessels of the brain.

Gene signature predicts prostate cancer survival Posted: 10 Oct 2012 12:12 PM PDT Researchers have identified a six-gene signature that can be used in a test to predict survival in men with aggressive prostate cancer.

Human neural stem cells study offers new hope for children with fatal brain diseases Posted: 10 Oct 2012 11:14 AM PDT Physician-scientists have demonstrated for the first time that banked human neural stem cells can survive and make functional myelin in mice with severe symptoms of myelin loss. Myelin is the critical fatty insulation, or sheath, surrounding new nerve fibers and is essential for normal brain function.

Melanoma: The wolf in sheep’s clothing Posted: 10 Oct 2012 11:11 AM PDT Melanoma is so dangerous because it tends to metastasize early on. New treatment approaches utilize, among other things, the ability of the immune defense to search out and destroy malignant cells. Yet this strategy is often only temporarily effective. A research team has discovered why this is the case: In the inflammatory reaction caused by the treatment, the tumor cells temporarily alter their external characteristics and thus become invisible to defense cells. This knowledge forms an important foundation for the improvement of combination therapies.

Squeezing ovarian cancer cells to predict metastatic potential: Cell stiffness as possible biomarker Posted: 10 Oct 2012 10:15 AM PDT New research shows that cell stiffness could be a valuable clue for doctors as they search for and treat cancerous cells before they're able to spread. The findings found that highly metastatic ovarian cancer cells are several times softer than less metastatic ovarian cancer cells.

RNA-based therapy brings new hope for an incurable blood cancer Posted: 10 Oct 2012 10:15 AM PDT A new class of drugs that interfere with the aggressive over-production of a protein related to Mantle Cell Lymphoma is being developed. The drugs have the ability to kill off the mutated protein and stop the over-proliferation of cells.

More about spatial memory problems associated with Alzheimer's revealed Posted: 10 Oct 2012 10:15 AM PDT Researchers have created a mouse model that reproduces some of the chemical changes in the brain that occur with Alzheimer's, shedding new light on this devastating disease.

Applying information theory to linguistics Posted: 10 Oct 2012 10:15 AM PDT Researchers believe that information theory -- the discipline that gave us digital communication -- can explain differences between human languages.

How the body uses vitamin B to recognize bacterial infection Posted: 10 Oct 2012 10:14 AM PDT An Australian research team has discovered how specialized immune cells recognize products of vitamin B synthesis that are unique to bacteria and yeast, triggering the body to fight infection.

Detailed view of brain protein structure; Results may help improve drugs for neurological disorders Posted: 10 Oct 2012 10:14 AM PDT Researchers have published the first highly detailed description of how neurotensin, a neuropeptide hormone which modulates nerve cell activity in the brain, interacts with its receptor. Their results suggest that neuropeptide hormones use a novel binding mechanism to activate a class of receptors called G-protein coupled receptors.

Zinc fingers: A new tool in the fight against Huntington's disease Posted: 10 Oct 2012 10:13 AM PDT Huntington's disease (HD) is an inherited genetic disorder caused by the multiple repetition of a DNA sequence (the nucleotides CAG) in the gene encoding a protein called "Huntingtin". People who do not suffer from the disease have this sequence repeated 10 to 29 times. But in an affected person, the triplet is present more than 35 times. New research provides positive results reducing the chromosomal expression of the mutant gene, which would prevent the development of disease.

Living near livestock may increase risk of acquiring MRSA Posted: 10 Oct 2012 10:13 AM PDT New study finds regional density of livestock is an important risk factor for nasal carriage of livestock-associated MRSA for persons with and without direct contact with livestock.

3-D model for lung cancer mimics the real thing Posted: 10 Oct 2012 10:13 AM PDT A new technique that allows scientists to grow lung cancer cells in three dimensions could accelerate discoveries for a type of cancer that has benefited little from scientific research over the last several decades. The model uses biological matter to form miniature lungs.

Does immune dysfunction contribute to schizophrenia? Genetic findings from new study Posted: 10 Oct 2012 07:20 AM PDT A new study reinforces the finding that a region of the genome involved in immune system function, called the major histocompatibility complex (MHC), is involved in the genetic susceptibility to schizophrenia.

Satiation hormone could increase risk of diabetes, heart attack and breast cancer in women Posted: 10 Oct 2012 06:28 AM PDT One of the body's satiation hormones, neurotensin, could raise women's risk of suffering one of three common and serious conditions: diabetes, cardiovascular disease and breast cancer. There is also a connection between the hormone and premature death in women, especially from cardiovascular disease.

Diabetic foot ulcers linked with higher risk of death, heart attack and stroke Posted: 10 Oct 2012 05:42 AM PDT People with diabetes who develop foot ulcers are at more risk of dying prematurely than those without the complication, finds a new large-scale study. The researchers say the findings highlight the potential need for improved detection and management of those with diabetes and foot ulcers.

HPV vaccination does not lead to an increase in sex, study suggests Posted: 10 Oct 2012 05:42 AM PDT Contrary to recent discussions, the HPV vaccination does not increase sexual activity in adolescent girls, new research shows. There have been claims recently that the HPV (Human papillomavirus) vaccination increases sexual activity in adolescent girls as it effectively gives them a 'green light' to have sex because of a perceived protection against sexually transmitted infections.

Nobel Prize in Chemistry 2012: Smart receptors on cell surfaces Posted: 10 Oct 2012 05:19 AM PDT Your body is a fine-tuned system of interactions between billions of cells. Each cell has tiny receptors that enable it to sense its environment, so it can adapt to new situtations. Robert Lefkowitz and Brian Kobilka have been awarded the 2012 Nobel Prize in Chemistry for groundbreaking discoveries that reveal the inner workings of an important family of such receptors: G-protein-coupled receptors.

HRT taken for 10 years significantly reduces risk of heart failure and heart attack, study suggests Posted: 09 Oct 2012 04:26 PM PDT Women who take HRT for 10 years following menopause have a significantly reduced risk of mortality, heart failure and heart attack without any increased risk of cancer, DVT or stroke, a new study suggests.

Rare genetic disorder points to molecules that may play role in schizophrenia Posted: 09 Oct 2012 02:14 PM PDT Scientists studying a rare genetic disorder have identified a molecular pathway that may play a role in schizophrenia, according to new research. The findings may one day guide researchers to new treatment options for people with schizophrenia -- a devastating disease that affects approximately 1% of the world's population.

Preterm labor powerhouse therapy offers promise for inflammatory diseases Posted: 09 Oct 2012 09:11 AM PDT Researchers recently discovered the mechanism by which magnesium reduces the production of cytokines. Cytokines are molecules responsible for regulating inflammation; they play a key role conditions, such as diabetes, obesity, atherosclerosis, asthma, and alcoholic liver disease and cirrhosis.
