About a third of US adults don’t get enough sleep. Unfortunately, sleep deprivation has serious consequences for your brain and body. Many people think they can get by on less than seven to nine hours per night – the amount of sleep doctors recommend for most adults – or say they need to sleep less because of work or family obligations. Tesla and SpaceX CEO Elon Musk recently acknowledged in an interview with the New York Times that his long work hours are taking a toll on his well-being and raising concerns among his friends. That prompted Ariana Huffington to post an open letter to Musk about his sleep schedule, telling him that he was “demonstrating a wildly outdated, anti-scientific and horribly inefficient way of using human energy.” Musk posted his response on Twitter at 2:30 a.m.: “I just got home from the factory. You think this is an option. It is not.” Musk seems to understand that working 120-hour weeks … [Read more...] about Sleep deprivation can kill you — here’s what sleeping less than 7 hours per night does to your body and brain
How does chronic inflammation cause cancer
Imagine Dragons frontman Dan Reynolds leads what most people consider a dream life: He's a rock star with a happy family and a Grammy under his belt. But what most fans might not know is that Reynolds has ankylosing spondylitis, an inflammatory disease that once caused the singer crippling amounts of pain. Reynolds is partnering with the Spondylitis Association of America and pharmaceutical company Novartis to speak about life with A.S. Q: What was your inspiration for "Next to Me"? A: It's a very personal song and the music video was definitely one of the most intense shoots I've ever done. It really pushed me to a different place, but I'm grateful for that. I love the song; it has a lot of meaning and I hope people like it. There's a lot of emotional weight to the video and I had to go to a really raw place to shoot it and the director really pushed us and put me in an uncomfortable place for a lot of it, which I'm grateful for. Q: You live with A.S. and you're a working … [Read more...] about Imagine Dragons’ Dan Reynolds on living with inflammatory disease A.S.
Could the no-calorie sweetener you rely on to replace sugar in your diet actually cause weight gain instead of the weight loss you were expecting?The answer may be yes, according to a new study."Artificial sweeteners are not risk-free," said Brian Hoffmann, assistant professor in the Department of Biomedical Engineering at the Medical College of Wisconsin and Marquette University, and a lead author of the study. "They are a very controversial topic when it comes to health and nutrition ... but they're so prevalent in society that I think we owe it to ourselves to try and figure out what's actually going on."Hoffmann presented his new research Sunday at the annual Experimental Biology meeting in San Diego. Relying on rats and human cell cultures, his team identified a number of pathways linking artificial sweeteners with metabolic changes at the genetic level that could lead to diabetes and obesity. Specifically, the researchers found that three weeks of exposure to … [Read more...] about Artificial sweeteners: Where do we stand?
By Stephen S. HallApr. 19, 2018 , 12:15 PM Nick Henry first experienced the symptoms of kidney disease in 2004, shortly after the 19-year-old had a severe reaction to a spider bite. "I woke up one morning, and I was just swollen from head to toe," he recalls. But doctors managed Henry's disease, allowing him to return to his unusually active lifestyle—including baseball, softball, basketball, flag football, golf, and fishing—in his northeast Louisiana hometown of West Monroe. Shortly after he witnessed the death of his mother in a motor scooter accident in 2012, however, Henry's renal health took a dramatic turn for the worse. "It's almost as if my body went into shock," he says. "Within a couple months, boom, I started swelling up again." That swelling was a sign that his kidneys were no longer working normally. A biopsy confirmed that he had focal segmental glomerulosclerosis (FSGS), a severe form of kidney disease. In FSGS, the kidney's glomeruli—the microscopic … [Read more...] about What’s your risk of kidney disease, heart attack, or diabetes? A single molecule can tell
By Mitch LeslieMar. 29, 2018 , 2:00 PM About 12 years ago, Gary Glick and his wife noticed something wrong with their son, Jeremy. He seemed to be lagging behind his twin sister, recalls the immunologist and chemical biologist at the University of Michigan in Ann Arbor. "They were growing in unison, and he sort of stopped." Jeremy, who was 9 or 10 at the time, also looked sickly and pale and began complaining of nagging pains in his stomach and elsewhere. Rachel Lipson Glick, a physician, was stumped by their son's mysterious ailment. So were other doctors. It took about 3 years to rule out myriad cancers, endocrine malfunctions, and other potential causes and to determine that Jeremy had Crohn disease, an inflammation of the digestive tract stoked by misbehaving immune cells. The diagnosis made life harder for Jeremy, now 22 and a senior at college. To control the symptoms, he injects the antibody drug adalimumab (Humira). He will likely need it, or another immune-inhibiting … [Read more...] about To treat some diseases, researchers are putting immune cells on a diet
