Molecular path from internal clock to cells controlling rest and activity revealed Posted: 07 Feb 2012 05:28 PM PST The molecular pathway that carries time-of-day signals from the body's internal clock to ultimately guide daily behavior is like a black box, says a researcher. Now, new research is taking a peek inside, describing a molecular pathway and its inner parts that connect the well-known clock neurons to cells governing rhythms of rest and activity in fruit flies.

Drinking large amounts of soft drinks associated with asthma and COPD Posted: 07 Feb 2012 05:28 PM PST A high level of soft drink consumption is associated with asthma and/or chronic obstructive pulmonary disease, according to new research.

Scientists use old theory to discover new targets in fight against breast cancer Posted: 07 Feb 2012 05:24 PM PST Reviving a theory first proposed in the late 1800s that the development of organs in the normal embryo and the development of cancers are related, scientists have studied organ development in mice to unravel how breast cancers, and perhaps other cancers, develop in people. Their findings provide new ways to predict and personalize the diagnosis and treatment of cancer.

Discovery uses 'fracture putty' to repair broken bone in days Posted: 07 Feb 2012 04:34 PM PST Broken bones in humans and animals are painful and often take months to heal. New research shows promise to shorten healing time significantly and revolutionize the course of fracture treatment.

Ovarian cancer risk related to inherited inflammation genes Posted: 07 Feb 2012 10:38 AM PST Genes that are known to be involved in inflammation were found to be related to risk of ovarian cancer.

New diet: Top off breakfast with -- chocolate cake? Posted: 07 Feb 2012 10:37 AM PST In a study of nearly 200 clinically obese, non-diabetic adults, a researcher found that a 600-calorie breakfast that includes dessert as well as proteins and carbohydrates can help dieters lose weight and keep it off over the long term. Her research indicates that such a morning meal staves off cravings and defuses psychological addictions to sweet foods.

Vitamin D deficiency high among trauma patients Posted: 07 Feb 2012 10:37 AM PST New research has found that 77 percent of trauma patients had deficient or insufficient levels of vitamin D.

Knee replacement may lower a patient's risk for mortality and heart failure, study suggests Posted: 07 Feb 2012 10:36 AM PST New research highlights the benefits of total knee replacement.

Competitive soccer linked to increased injuries and menstrual dysfunction in girls Posted: 07 Feb 2012 10:36 AM PST In the US, there are nearly three million youth soccer players, and half of them are female. New research has found that despite reporting appropriate body perception and attitudes toward eating, elite youth soccer athletes face an increased risk for delayed or irregular menstruation.

First remote-control leg lengthening implant cleared by the FDA Posted: 07 Feb 2012 09:19 AM PST A revolutionary new limb lengthening system developed by orthopedic surgeons represents a major advancement in the treatment of limb deformities.

New anti-aging treatments make it easier to turn back the clock Posted: 07 Feb 2012 09:18 AM PST As we age, our skin undergoes a number of changes affecting its texture, volume and appearance. Fortunately, dermatologists can use fillers or lasers to correct the most notable signs of aging and can recommend skin care products with added ingredients that can further repair damaged skin.

Study of live human neurons reveals Parkinson's origins Posted: 07 Feb 2012 09:18 AM PST Parkinson's disease researchers have discovered how mutations in the parkin gene cause the disease, which afflicts at least 500,000 Americans and for which there is no cure.

Why bad immunity genes survive: Study implicates arms race between genes and germs Posted: 07 Feb 2012 09:18 AM PST Biologists have found new evidence for why mice, people and other vertebrate animals carry thousands of varieties of genes to make immune-system proteins named MHCs -- even though some of those genes make us sick.

The dark path to antisocial personality disorder Posted: 07 Feb 2012 07:00 AM PST With no lab tests to guide the clinician, psychiatric diagnostics is challenging and controversial. Antisocial personality disorder is defined as "a pervasive pattern of disregard for, and violation of, the rights of others that begins in childhood or early adolescence and continues into adulthood," according to a standard definition. But, until now, no one has studied the dimensional structure associated with the DSM antisocial personality disorder criteria.

Why the middle finger has such a slow connection Posted: 07 Feb 2012 07:00 AM PST Each part of the body has its own nerve cell area in the brain -- we therefore have a map of our bodies in our heads. The functional significance of these maps is largely unclear. What effects they can have is now shown by neuroscientists through reaction time measurements combined with learning experiments and "computational modeling." They have been able to demonstrate that inhibitory influences of neighboring "finger nerve cells" affect the reaction time of a finger.

Rapid bone loss as possible side effect of anti-obesity drug Posted: 07 Feb 2012 06:56 AM PST An endocrine hormone used in clinical trials as an anti-obesity and anti-diabetes drug causes significant and rapid bone loss in mice, raising concerns about its safe use, researchers have shown.

Smoking associated with more rapid cognitive decline in men Posted: 06 Feb 2012 01:46 PM PST Smoking in men appears to be associated with more rapid cognitive decline, according to a new report.

Sharp images from the living mouse brain Posted: 06 Feb 2012 09:24 AM PST Scientists have for the first time made finest details of nerve cells in the brain of a living mouse visible.

Zinc linked to breast cancer: Insight into body's zinc controls has implications for disease Posted: 06 Feb 2012 07:29 AM PST Zinc has long been known to play a vital part in human health. However, the mechanisms for delivering zinc into cells are not well understood. New research has identified one switch which allows zinc to flow. This has implications for a number of diseases, including aggressive types of breast cancer.

Researchers develop method of directing stem cells to increase bone formation and bone strength Posted: 06 Feb 2012 06:26 AM PST Scientists have developed a novel technique to enhance bone growth by using a molecule which, when injected into the bloodstream, directs the body's stem cells to travel to the surface of bones.

New virtual tool may provide more accurate diagnosis of genetic mutations Posted: 06 Feb 2012 06:26 AM PST DNA sequencing to detect genetic mutations can aid in the diagnosis and selection of treatment for cancer. Current methods of testing DNA samples, Sanger sequencing and pyrosequencing, occasionally produce complex results that can be difficult or impossible to interpret. Scientists have now developed a free software program, Pyromaker, that can more accurately identify such complex genetic mutations.

Dieting with the denomination, determination Posted: 03 Feb 2012 11:16 AM PST According to a new study, those starting new weight loss programs may be surprised to find out that both location and level of experience may influence their success. A recent article finds that African-American women beginning a new group weight loss program are more successful if they are less experienced with weight management and if the program meets in a church.

Holding back immunity: 'Gatekeeper' protein key to helping immune cells to sound warning Posted: 03 Feb 2012 06:08 AM PST A 'gatekeeper' protein plays a critical role in helping immune cells to sound a warning after encountering signs of tumor growth or infection, researchers report.
