Taking B vitamins won't prevent Alzheimer's disease Posted: 15 Jul 2014 06:55 AM PDT Taking B vitamins doesn't slow mental decline as we age, nor is it likely to prevent Alzheimer's disease, conclude researchers who have assembled all the best clinical trial data involving 22,000 people to offer a final answer on this debate. When looking at measures of global cognitive function -- or scores for specific mental processes such as memory, speed or executive function -- there was no difference between those on B vitamins and those receiving placebo to a high degree of accuracy.

SIDS risks vary by infant age: Bed sharing remains greatest risk factor for sleep related infant deaths Posted: 14 Jul 2014 06:39 PM PDT Sudden infant death syndrome and other sleep-related causes of infant mortality have several known risk factors, but little is known if these factors change for different age groups.

Study: Young women with sexy social media photos seen as less competent Posted: 14 Jul 2014 03:24 PM PDT Girls and young women who post sexy or revealing photos on social media sites are viewed by their female peers as less attractive and less competent to perform tasks, a new study indicates. One researcher's advice for girls and young women is to select social media photos that showcase their identity rather than her appearance, such as one from a trip or one that highlights participation in a sport or hobby.

Older adults nearly twice as likely to have memories affected by distractions Posted: 14 Jul 2014 03:24 PM PDT Older people are nearly twice as likely as their younger counterparts to have their memory and cognitive processes impaired by environmental distractions.

Genome-wide analysis reveals genetic similarities among friends: Study finds truth to 'friends are the family you choose' Posted: 14 Jul 2014 12:23 PM PDT If you consider your friends family, you may be on to something. A new study finds that friends who are not biologically related still resemble each other genetically.

Months before their first words, babies' brains rehearse speech mechanics Posted: 14 Jul 2014 12:23 PM PDT New research in 7- and 11-month-old infants shows that speech sounds stimulate areas of the brain that coordinate and plan motor movements for speech. The study suggests that baby brains start laying down the groundwork of how to form words long before they actually begin to speak.

Say 'no' to interruptions, 'yes' to better work Posted: 14 Jul 2014 09:26 AM PDT Modern office workers are expected to multitask regularly, often juggling multiple projects and priorities over the course of a day. Studies have shown that the typical employee in an office environment is interrupted up to six times per hour, but how does that impact the finished product? New research evaluates how ongoing interruptions can negatively affect the quality of work.

Physical fitness associated with less pronounced effect of sedentary behavior Posted: 14 Jul 2014 07:40 AM PDT Physical fitness may buffer some of the adverse health effects of too much sitting, according to a new study. Sedentary behavior has been linked to an increase risk of obesity, metabolic syndrome, type 2 diabetes mellitus, cardiovascular disease, some cancers, and premature death. But previous studies of the association have not taken into account the protective impact of fitness, a strong predictor of cardiovascular disease incidence and mortality.
