Here’s what I am reading today:
“After 31-year-old Zac Vawter lost part of his leg in a motorcycle accident, a team of doctors set out to create a new kind of prosthetic limb: one whose motions he could manipulate with his mind, by “flexing” a foot that was no longer there. The method is similar to one already tried in people who have lost an arm: The doctors at Northwestern University and the Rehabilitation Institute of Chicago removed nerves from damaged muscle in Vawter’s amputated leg and connected them to hamstring muscle in his thigh, which had been left intact.”
“”The study underscores that obesity and other eating disorders have a neurological basis,” said senior study author Garret Stuber, PhD, assistant professor in the department of psychiatry and department of cell biology and physiology. He’s also a member of the UNC Neuroscience Center. “With further study, we could figure out how to regulate the activity of cells in a specific region of the brain and develop treatments.”"
“Thousands of North Texans are asking, “What are those long, silky strings floating in the air?” Turns out they’re the webs of spiders in their annual migration to better hunting grounds, and surprising a lot of people.
“I thought it was weird; I’d never seen it before,” said Myrna Olivas, who first noticed it driving in her car;”
“One theory about autism is that it may start in the gut, because some children with the disorder also suffer from gastrointestinal problems. Many are put on strict gluten-free diets in the hopes that avoiding wheat proteins will improve their behavior.
“Studies have not really shown that this works, but it is a common belief,” said Dr. Daniel Coury, chief of developmental-behavioral pediatrics at Nationwide Children’s Hospital in Columbus, Ohio.
The new study, which was published online Sept. 25 in the journal JAMA Psychiatry, offers the most definitive proof yet that many autistic kids don’t benefit from restrictive, wheat-free diets.”
“University of Sussex neuroscientists took fMRI scans of champion ‘mental calculator’ Yusnier Viera during arithmetical tasks that were either familiar or unfamiliar to him and found that his brain did not behave in an extraordinary or unusual way.
The paper, published this week (23 September 2013) in PloS One, provides scientific evidence that some calculation abilities are a matter of practice. Co-author Dr Natasha Sigala says: “This is a message of hope for all of us. Experts are made, not born.”"
““I also shattered illusions of my immortality. I was paralyzed from here”—she hold her hands at her hips—“down. No movement and no sensation.” That life changed radically for her right then is difficult to dispute. But Boxtel eventually embraced a road to recovery. “It took time to turn wounds into wisdom. It took guts. This is a cruel injury. It is so much more than not being able to walk,” she tells us.”
“Peter Turchin, a population dynamicist at the University of Connecticut in Storrs, and his colleagues set out to understand why social institutions came about when they were costly for individuals to build and maintain. “Our model says they spread because they helped societies compete against each other,” says Turchin. The results are published in the Proceedings of the National Academy of Sciences1.”
