The less older adults sleep, the faster their brains age, new study suggests
Researchers have found evidence that the less older adults sleep, the faster their brains age. These findings, relevant in the context of a rapidly ageing society, pave the way for future work on sleep loss and its contribution to cognitive decline, including dementia.
Exercise is the best medicine, study shows
Women would benefit from being prescribed exercise as medicine, according to a study that revealed moderate to high intensity activity is essential to reducing the risk of death in older women. “What we are saying is that high-intensity exercise is not only good for your physical health but also your brain health. Doctors should be developing exercise programs that are home-based and easy to incorporate as part of everyday activities,” authors say.
Do women perceive other women in red as more sexually receptive?
Women are more likely to wear a red shirt when they are expecting to meet an attractive man, relative to an unattractive man or a woman. But do women view other women in red as being more sexually receptive? And would that result in a woman guarding her mate against a woman in red? A study has sought to answer these questions.
High stress, hostility, depression linked with increased stroke risk
Higher levels of stress, hostility and depressive symptoms are associated with significantly increased risk of stroke or transient ischemic attack (TIA) in middle-age and older adults, according to new research. A TIA is a stroke caused by a temporary blockage of blood flow to the brain.
Young adults’ privacy potentially jeopardized by insurance plans, researchers report
Violations of privacy are increasing as more adolescents and young adults gain coverage on their parents’ health insurance plans, according to a new health policy report. Under the Affordable Care Act (ACA), adult children now can stay on their parents’ health insurance plans until they reach age 26. But because they are dependents on their parents’ health insurance, they are not afforded the same confidentiality protections as if they had individual plans.
Harmful hookahs: Many young smokers aren’t aware of danger
Despite warnings that hookah smoking can be just as dangerous as cigarettes, many young adults believe that using the water pipes is not harmful to their health, according to a study. “With hookah smoking on the rise, particularly among young adults, our goal was to identify factors influencing perceptions, attitudes and preferences toward hookah smoking,” said the lead researcher.
How to make a clarinet out of a carrot
An Australian musician walked into a TEDx Talk with a drill, a carrot, a mouthpiece and a funnel — then succeeded in stunning the audience by using these items to create something “awesome.” In five mere minutes, Linsey Pollak transformed the ordinary carrot into a real-sounding clarinet and played it live. Watch the construction and the mini “carrot concert” that’s fun for the whole family.
Squid sucker ring teeth material could aid reconstructive surgery, serve as eco-packaging
Squid tentacles are loaded with hundreds of suction cups, or suckers, and each sucker has a ring of razor-sharp ‘teeth’ that help these mighty predators latch onto and take down prey. Researchers report that the proteins in these teeth could form the basis for a new generation of strong, but malleable, materials that could someday be used for reconstructive surgery, eco-friendly packaging and many other applications.
Red wine with or without alcohol and wine with grape seed extract were the most effective at getting rid of the bacteria. Observing: “almost complete and early degradation … when incubating biofilms with the red wine extract,” the study authors submit that: “this is the first study of antimicrobial properties of wine in an oral biofilm model.”
Omega-3s Reduce Deadly Blood Clot Risks
A diet abundant in fish, combined with omega-3 fatty acid supplementation, may reduce the risk of venous thromboembolism by nearly 50%
Fitness in 50s Is An Anti-Aging Essential
Poor physical ability in your 50s may raise your risk of an early death.
Lack of Sleep Compromises the Brain
After a night of no sleep, even a healthy brain has elevated levels of amyloid-beta, the protein that characterizes Alzheimer’s Disease.
Sitting too much, not just lack of exercise, is detrimental to cardiovascular health
Cardiologists have found that sedentary behaviors may lower cardiorespiratory fitness levels. New evidence suggests that two hours of sedentary behavior can be just as harmful as 20 minutes of exercise is beneficial.
Less exercise, not more calories, responsible for expanding waistlines
Sedentary lifestyle and not caloric intake may be to blame for increased obesity in the US, according to a new analysis. A study reveals that in the past 20 years there has been a sharp decrease in physical exercise and an increase in average body mass index (BMI), while caloric intake has remained steady. Investigators theorized that a nationwide drop in leisure-time physical activity, especially among young women, may be responsible for the upward trend in obesity rates.
Vitamin D ups bowel cancer survival odds, study finds
Bowel cancer patients with high levels of vitamin D in their blood are more likely to survive the disease, a study shows. Patients with the highest levels of vitamin D have half the risk of dying compared with those with the lowest levels, the findings reveal. The study is the first to correlate total blood levels of vitamin D in bowel cancer patients after their diagnosis — which includes that produced after exposure to sunlight and that obtained from dietary sources — with their long term survival prospects.
Number of registered nurses grows as professionals delay retirement
Between 1969 and 1990, about 47 percent of nurses still worked by age 62 and 9 percent still worked at age 69. However those percentages increased from 1991 to 2012, with 74 percent of nurses working at 62 and 24 percent working at age 69, according to the study. This could create a problem for new nursing grads, who may struggle more than their past counterparts to find a job, Auerbach said.
Slow walking speed, memory complaints can predict dementia
A study involving nearly 27,000 older adults on five continents found that nearly 1 in 10 met criteria for pre-dementia based on a simple test that measures how fast people walk and whether they have cognitive complaints. People who tested positive for pre-dementia were twice as likely as others to develop dementia within 12 years.
Does responsiveness increase sexual desire in the other person? Do men perceive responsive women as more attractive, and does the same hold true for women’s perceptions of men? A recent study undertook to answer those questions.
Total darkness at night key to success of breast cancer therapy, study shows
Exposure to light at night, which shuts off nighttime production of the hormone melatonin, renders breast cancer completely resistant to tamoxifen, a widely used breast cancer drug, says a new study. Melatonin by itself delayed the formation of tumors and significantly slowed their growth, researchers report, but tamoxifen caused a dramatic regression of tumors in animals with either high nighttime levels of melatonin during complete darkness or those receiving melatonin supplementation during dim light at night exposure.
