Key driver for treatment of deadly brain cancer Posted: 08 Jan 2016 05:09 PM PST A factor in how malignant tumors spread may also be a key to treatment.

New brief recommends increased insurance coverage for exercise programming for individuals with mental illness Posted: 08 Jan 2016 10:50 AM PST A new statement supporting increased coverage of exercise programming by health plans for individuals with mental illnesses has been released. The brief includes an assessment of current policies and recommends policy actions to state and federal policy makers, allied health professionals and state and federal mental health administrators.

Bite-mark analysis can lead to false convictions, landmark research shows Posted: 08 Jan 2016 10:49 AM PST Forensic science is a vital crime-fighting tool in today's criminal justice system. But it can also lead to false convictions, according to an expert, whose study proves that bite-mark analysis is "far from an exact science."

Retinal cells work with little reserve energy; may explain vulnerability to eye diseases Posted: 08 Jan 2016 10:48 AM PST Our eyes are especially demanding when it comes to energy: along with our brain, they require a substantial amount of power to keep them functioning and healthy. Now a new study suggests that because of their high-energy demands, our eyes function at high efficiency and with little reserve capacity, which scientists say may explain why they become vulnerable to degenerative diseases.

Research reveals advice given on internet health forums may not be as dangerous as often assumed Posted: 08 Jan 2016 10:46 AM PST New research suggests that medical advice given on internet health forums may be of better quality than people tend to assume.

Researchers reveal mechanisms of how body remembers, fights infections Posted: 08 Jan 2016 10:43 AM PST Scientists have found a potential way to influence long-term memory formation in the immune system.

Turning on the thyroid Posted: 08 Jan 2016 10:42 AM PST Despite the prevalence of thyroid disease and its sometimes serious effects, researchers have struggled to answer a pretty basic question about the hormone-producing gland: What turns it on? A new study provides an answer, and that answer was found within the gland itself.

How copper makes organic light-emitting diodes more efficient Posted: 08 Jan 2016 05:44 AM PST Use of copper as a fluorescent material allows for the manufacture of inexpensive and environmentally compatible organic light-emitting diodes (OLEDs). Thermally activated delayed fuorescence (TADF) ensures high light yield. Scientists of Karlsruhe Institute of Technology (KIT), CYNORA, and the University of St Andrews have now measured the underlying quantum mechanics phenomenon of intersystem crossing in a copper complex. The results of this fundamental work are reported in the Science Advances journal and contribute to enhancing the energy efficiency of OLEDs.

Low-cost 3-D printer-based organ model production technique reveals complicated interior organ structure Posted: 08 Jan 2016 05:39 AM PST Researchers in Japan have successfully developed a low-cost human organ model production technique for use with 3-D printers that helps reveal complicated interior organ structure.

Biofilter made from peanut shell degrades air pollutants Posted: 08 Jan 2016 05:39 AM PST In order to clean the air of pollutants such as methanol and solvents used in various industries, a biotechnology expert designed a biofilter that uses microorganisms living in the shell of the peanut.

Having more children slows down aging process Posted: 08 Jan 2016 05:37 AM PST Researchers suggest the number of children born to a woman influences the rate at which her body ages. Health sciences researchers found women who give birth to more surviving children exhibited longer telomeres. Telomeres are the protective tips at the end of each DNA strand and are indicative of cellular aging. Longer telomeres are integral to cell replication and associated with longevity.

Ebola medical team develops guidelines for treating infected children Posted: 08 Jan 2016 05:34 AM PST When the Ebola virus outbreak erupted in West Africa in 2014, children infected with the virus -- particularly those under age 5 -- faced a high risk of death. Researchers involved in their treatment have since developed a set of guidelines aimed at improving how they're treated. They suggest an aggressive approach that includes giving children fluids intravenously; treating other possible infections; feeding them highly fortified food; and increasing the amount of bedside care they receive.

Genome-wide study in Labradors reveals a modifier gene for copper toxicosis Posted: 08 Jan 2016 05:34 AM PST In Wilson disease, copper accumulates to toxic levels in tissues, causing neurological symptoms and liver disease. Diagnosis is challenging because symptoms can vary widely across patients, and the mechanisms underlying this clinical heterogeneity are unclear. Using a genome-wide approach in a new dog model for copper toxicosis, researchers have now revealed that mutations in a copper transporter gene, ATP7A, can ameliorate symptoms. This finding could pave the way for early detection and treatment of hereditary copper metabolism disorders.

Confident body, confident child: Breakthrough parent training program shows promise in promoting body satisfaction and healthy eating Posted: 07 Jan 2016 03:55 PM PST A new study has demonstrated positive results in reducing potential vulnerabilities for disordered eating and promoting body satisfaction, healthy eating and weight management among young children through a novel intervention for parents.

Study aims to lower blood pressure among adults in rural southeast asia Posted: 07 Jan 2016 03:54 PM PST Researchers are launching a study to find cost-effective ways of lowering blood pressure in adults living in rural in South Asia. Hypertension, or high blood pressure, is a major risk factor for heart attack, stroke, and other vascular diseases that are often under-recognized in developing countries. Lowering blood pressure is thought to be the single most important way to reduce deaths and disabilities from heart attacks and strokes.

Study finds gaps in patient knowledge of breast reconstruction surgery, complications Posted: 07 Jan 2016 03:52 PM PST Breast cancer patients surveyed about their knowledge of breast reconstruction were only moderately informed about the procedure, and their knowledge of complications was low, a new study has demonstrated.
