Midlife physical activity is associated with better cognition in old age Posted: 09 Sep 2016 06:50 AM PDT Moderately vigorous physical activity -- for example, more strenuous than walking -- has been found to be associated with better cognition in a 25-year follow-up, a new study of 3050 twins finds.

Novel heart valve replacement offers hope for thousands with rheumatic heart disease Posted: 09 Sep 2016 06:48 AM PDT A novel heart valve replacement method offers hope for the thousands of patients with rheumatic heart disease who need the procedure each year, say experts.

Researchers outline barriers to treating fear, anxiety Posted: 09 Sep 2016 06:48 AM PDT A misunderstanding of how the certain parts of the brain function has hampered the creation of pharmaceuticals to effectively address fear and anxiety disorders, a pair of researchers has concluded.

Three in four don't know obesity causes cancer Posted: 08 Sep 2016 05:39 PM PDT Three out of four people in the United Kingdom are unaware of the link between obesity and cancer, according to a new report. The nationwide survey found that people from lower socioeconomic backgrounds are less likely to know about the link. And men are less likely than women to be aware of the increased risk of cancer caused by obesity.

Major review to help doctors, patients and public make informed decisions about the use of statins Posted: 08 Sep 2016 05:39 PM PDT A major review of the available evidence on the safety and efficacy of statin therapy intends to help doctors, patients and the public make informed decisions about the use of the drugs. The authors warn that the benefits of statin therapy have been underestimated, and the harms exaggerated, because of a failure to acknowledge properly both the wealth of evidence from randomized trials and the limitations of other types of studies.

New strategy may help prevent kidney failure in patients with diabetes Posted: 08 Sep 2016 05:38 PM PDT A new strategy may help halt the progression of kidney disease in patients with diabetes. The approach addresses a common and serious complication of diabetes.

Linking RNA structure and function Posted: 08 Sep 2016 01:49 PM PDT Several years ago, biologists discovered a new type of genetic material known as long noncoding RNA. This RNA does not code for proteins and is copied from sections of the genome once believed to be "junk DNA." Now, in a related study, biologists have discovered how an enigmatic type of RNA helps to control cell fate.

Newly discovered infectious prion structure shines light on mad cow disease Posted: 08 Sep 2016 12:12 PM PDT Groundbreaking research has identified the structure of the infectious prion protein, the cause of 'mad cow disease' or BSE, chronic wasting disease in deer and elk and Creutzfeldt-Jakob disease in humans, which has long remained a mystery.

Study looks at how parents use newborn screening results Posted: 08 Sep 2016 12:11 PM PDT Parents say they want to know everything that turns up in newborn screening tests, but then don't use the information or use it inappropriately, new research indicates.

Scientists film bacteria's maneuvers as they become impervious to drugs Posted: 08 Sep 2016 12:09 PM PDT In a creative stroke inspired by Hollywood wizardry, scientists have designed a simple way to observe how bacteria move as they become impervious to drugs.

Chronic sinusitis associated with certain rare head and neck cancers among elderly Posted: 08 Sep 2016 08:57 AM PDT The associations of chronic sinusitis with subsequent head and neck cancer in an elderly population have been evaluated in a new study. Acute sinusitis is a common inflammatory condition of the sinuses often caused by viral or bacterial infections. The condition is considered chronic when the episode persists longer than 12 weeks.

Robotic surrogates help chronically ill kids maintain social, academic ties at school Posted: 07 Sep 2016 01:06 PM PDT Chronically ill, homebound children who use robotic surrogates to "attend" school feel more socially connected with their peers and more involved academically, according to a first-of-its-kind study.

RNA test detects bacterial infections in infants with fever Posted: 07 Sep 2016 01:06 PM PDT A blood test used to measure patterns of ribonucleic acid (RNA) expression can help determine if fever in infants under 2 months old is caused by bacterial or viral infection, according to a preliminary study.
