New glasses may help minimize peripheral vision loss Posted: 16 Dec 2016 04:22 PM PST Vision scientists may have discovered how to reduce pedestrian collisions in crowded and chaotic open space environments like bus terminals, shopping malls and city plazas involving individuals with partial blindness. Researchers have determined from which direction collisions with partially blind pedestrians are most likely to originate. This understanding will guide the development of new glasses that expand the sight of a person with limited peripheral vision.

New bioinformatics tool tests methods for finding mutant genes that ‘drive’ cancer Posted: 16 Dec 2016 11:26 AM PST Computational scientists and cancer experts have devised bioinformatics software to evaluate how well current strategies distinguish cancer-promoting mutations from benign mutations in cancer cells.

Lowering cholesterol to 'levels of a new-born baby' cuts heart attack risk Posted: 16 Dec 2016 08:43 AM PST Reducing our cholesterol levels to those of a new-born baby significantly lowers the risk of cardiovascular disease, according to new research.

Certain high blood pressure drugs block cancer invasion Posted: 16 Dec 2016 08:41 AM PST Researchers have identified a new way of blocking the spread of cancer. Calcium channel blockers, which are used to lower blood pressure, block breast and pancreatic cancer invasion by inhibiting cellular structures.

Frequent sauna bathing protects men against dementia Posted: 16 Dec 2016 08:41 AM PST Frequent sauna bathing can reduce the risk of dementia, according to a recent study. In a 20-year follow-up, men taking a sauna 4-7 times a week were 66% less likely to be diagnosed with dementia than those taking a sauna once a week. The association between sauna bathing and dementia risk has not been previously investigated.

Computer model predicts potential impact of short-course therapy against multidrug-resistant TB Posted: 15 Dec 2016 04:17 PM PST Researchers have developed a computer simulation that helps predict under which circumstances a new short-course treatment regimen for drug-resistant tuberculosis could substantially reduce the global incidence and spread of the disease.

UK soft drinks industry levy estimated to have significant health benefits, especially among children Posted: 15 Dec 2016 04:16 PM PST Reducing sugar content of high and mid sugar drinks is likely to have the greatest impact on health, with fewer cases of obesity, diabetes and tooth decay. The UK soft drinks industry levy, due to be introduced in April 2018, is estimated to have significant health benefits, especially among children, according to the first study to estimate its health impact.

Research locates absence epilepsy seizure 'choke point' in brain Posted: 15 Dec 2016 11:35 AM PST Researchers used a rodent model to discover that shifting the firing pattern of a particular set of brain cells is all it takes to initiate, or to terminate, an absence seizure.

Coping mechanism suggests new way to make cancer cells more vulnerable to chemotherapies Posted: 15 Dec 2016 09:59 AM PST The same signal that drives aggressive growth in a deadly cancer cell type also triggers coping mechanisms that make it 'notoriously' hard to kill.

Depressed children respond differently to rewards than other kids Posted: 15 Dec 2016 09:47 AM PST Adults and teenagers with depression don't respond to rewards in a normal manner. Although depression has been diagnosed in children as young as 3, it hasn't been clear whether their responses to rewards also may be blunted. So researchers studied kids ages 4 to 7 and found that, like adults, when the children were depressed, their brains were less likely to respond to rewards. The researchers say insensitivity to rewards may serve as a "red flag" for depression in young children.

Search on for drug to tame 'hyperactive' zinc transporter and lower type 2 diabetes risk Posted: 15 Dec 2016 09:47 AM PST Gene variants associated with disease are typically considered faulty, and problems arise when the proteins they make don't adequately carry out their designated role, report scientists.

Gastric cancer fueled by 'crosstalk' between nerves, cancer cells Posted: 15 Dec 2016 09:47 AM PST Gastric tumors are started by specialized cells in the stomach that signal nerves to make more acetylcholine, according to a study in mice. But blocking nerve growth factor inhibits the formation of stomach tumors.

Neurons anticipate body's response to food and water Posted: 15 Dec 2016 09:47 AM PST A new discovery offers new insight into regulation of water and food intake. Neuroscientists recorded neuronal activity in real-time in awake mice when presented with food or water, and identified anticipatory changes in neuronal activity in the seconds prior to drinking.

Psychologists analyze links between provider burnout, quality of care, patient safety Posted: 15 Dec 2016 05:59 AM PST Psychologists conducted a meta-analysis of 82 studies in the first study to systematically, quantitatively analyze the links between health care provider burnout and health care quality and safety across medical disciplines.
