More schools are starting classes later to let students sleep

More schools are starting classes later to let students sleep

Health
The Seattle school district joined dozens of school districts around the country in the fall of 2016 by delaying the start of school. Under the new rules, instead of beginning at 7:50 a.m., they began at 8:45 a.m. This gave researchers at the University of Washington an opportunity to determine just how much teens need sleep. In a new study, they used activity monitors to study a group of high school sophomores before and after the changes were implemented and found that with later start times, students were not only getting an extra half-hour of sleep, their grades had improved by nearly 5 percentage points too. Sleep is important for everyone, but even more so for teens, who are constantly losing sleep because of their busy schedules. Here’s why they need it even more: Studi...
Breastfeeding linked to reduced risk of stroke later in life

Breastfeeding linked to reduced risk of stroke later in life

Health
Stroke is the third-leading cause of death for women, according to the Centers for Disease Control and Prevention (CDC). A new study from the American Heart Association (AHA) says breastfeeding may be added to the list of ways to reduce the risk of stroke later in life. Several risk factors (such as diabetes, high blood pressure, and smoking) and protective factors (such as controlling blood sugar and blood pressure and exercising), have been identified for stroke by the American Stroke Association. To find this new protective factor, researchers from the University of Kansas looked at data from 80,191 women from The Women’s Health Initiative Observational Study, which tracked the health habits and medical outcomes for women between 1993 and 1998. At this time, the average age of ...

World
Two men surfing off the western coast of Australia are lucky to be alive after getting attacked by sharks. Australia’s 9News reported that Jason Longrass, 41, and Alejandro Travaglini, 37, were attacked in two separate incidents less than a mile from each other on Monday in Gracetown. In dramatic video posted on 9News, Travaglini is seen being taken care of by friends before he was flown by helicopter to Perth Royal Hospital for emergency surgery. "He was punching the shark, and, like, there was three attacks, three different attacks in 20 seconds," Mikel Basanies told 9News. The Australian media station reported the Argentinian-born surfer was bit on both legs at just before 8:30 a.m. He was stable after surgery, according to 9News. Just hours later, another attack by what Longrass

Omega-3 fatty acids—DHA in particular—contribute to a healthy brain. “The brain’s membranes use these fats to improve cellular structure and brain signaling, which translates into better cognitive function,” says Vasanti Malik, ScD, a research scientist in the Department of Nutrition at the Harvard T.H. Chan School of Public Health. DHA also quells chronic inflammation that can harm brain cells and lead to cognitive decline.Fish is the top source: Eating fatty fish (like salmon, sardines, mackerel, or trout) once a week can help slow cognitive decline and reduce Alzheimer’s risk, research suggests. You can also get omega-3s from walnuts, chia seeds, flaxseed, and hempseed.Let's block ads! (Why?) Food - Health.com
Twice-dead star explodes 50 years later

Twice-dead star explodes 50 years later

Science
Nov. 8 (UPI) -- It's the star that keeps on dying -- astronomers have discovered a star that's exploded several times over the last half-century.Scientists first noted supernova iPTF14hls in September 2014. The fresh explosion seemed like the average type II-P supernova. The glow of such explosions usually last for 100 days. This supernova remained bright for 600 days.When researchers examined archival observations of this specific spot in the sky, they found a 1954 explosion in the very same location.Apparently, the star suffered a fiery near-death explosion, survived, and then exploded again five decades later."This supernova breaks everything we thought we knew about how they work," Iair Arcavi, an astronomer at the University of California Santa Barbara and Las Cumbres Observatory, sai...
