When researchers at the UCSD wanted to study an experimental Alzheimer’s drug last year, they sought help from an unlikely group: people with Down syndrome.  Alzheimer’s researchers are increasingly interested in people like McCowan because “people with Down syndrome represent the world’s largest population of individuals predisposed to getting Alzheimer’s disease,” says Michael Rafii, director of the Memory Disorders Clinic at UCSD. Down syndrome is a genetic disorder that’s best known for causing intellectual disability. But it also causes Alzheimer’s. “By the age of 40, 100 percent of all individuals with Down syndrome have the pathology of Alzheimer’s in their brain,” Rafii says.

Researchers find that drinking coffee, which is a source of antioxidants, appears to curb tooth loss due to gum disease.

OHSU doctor: Many C-sections unnecessary

Posted by: Administrator in News |

http://bcove.me/pbsxsf44

Some health experts now believe it's because doctors are using an outdated definition of labor and many of those C-sections are not necessary. Dr. Aaron Caughey is the chair of obstetrics and gynecology at Oregon Health & Science University. "In the old data you'd say, 'Gosh, you're 4 centimeters. If you're not 5 centimeters by a couple hours from now we're going to throw in the towel,'" Caughey explained. "Where now we say it could take four, five, six hours to go from 4 to 5 centimeters." Caughey says many midwives are already practicing the newer ways of letting the woman "push" for longer. But he says many in the medical field are still using the old methods. "We need to change practices," he said.

That dreaded moment your hard drive crashes. Do you know where to turn? Consumer Reports can tell you the best places to fix a failed computer, after surveying more than 4,400 computer owners about their experiences with tech support. PC owners told Consumer Reports that they were very dissatisfied with the support they got. That was regardless of whether they went on the phone for support, or went online. The survey found another good bet for tech support is independent computer stores. When it comes to troubleshooting.

USU researchers hack self-driving cars to foresee future risk

While companies like Google and Ford show off their designs for futuristic, self-driving cars, Associate Professor of Engineering Ryan Gerdes wants to know how to break the vehicles. "Autonomous vehicles will be hacked in the future," Gerdes said. "We really want to avoid the where you ever hear about somebody hacking into a vehicle and causing an accident." Gerdes, and a team of engineering students at Utah State University, will work to improve the security of autonomous vehicles before they ever hit the consumer market.While Gerdes says his team could never create a hack-proof system, their focus is to make sure cars can adjust safely if a malicious vehicle is on the road or if someone tries manipulate information or traffic data the cars would receive.

Peeing in the ocean: Is it OK?

http://www.cbc.ca/player/News/Canada/BC/ID/2493929506/

Go ahead and pee, says a new video from the American Chemical Society, an association of professional chemists and chemical engineers. The video points out that urine is almost entirely made of water, sodium and chloride, which are already found in large quantities in the ocean. Pee does contain a tiny bit of the waste product urea, but the amount is minuscule compared to the 350 quintillion liters of water in the Atlantic Ocean alone. Besides, the video suggests, the urea may be good for the environment: "Urea contains a lot of nitrogen. Nitrogen combines with water to produce ammonium which feeds ocean plant life."

Good Neighbors Are Good for Your Health

A study published recently in the Journal of Epidemiology & Community Health suggests your community matters in matters of the heart. Researchers tracked the cardiovascular health of more than 5,000 seniors with no known heart problems over four years. In 2006, participants in the Health and Retirements Study were asked how much they felt a part of their neighborhood, if they had neighbors who would help them, whether they trusted people in the area and if their neighbors were friendly. During the study period, 148 of the participants had a heart attack. Researchers found people who reported feeling more "social cohesion" were less at risk. Tight-knit local communities may help to reinforce and encourage certain types of behaviors that protect against cardiovascular damage, the study authors say.

How Long Do CDs Last? It Depends, But Definitely Not Forever

Posted by: Administrator in Science & Technology |

http://www.npr.org/blogs/alltechconsidered/2014/08/18/340716269/how-long-do-cds-last-it-depends-but-definitely-not-forever

Many institutions have their archives stored on CDs — but the discs aren't as stable as once thought. There is no average life span for a CD, says preservationist Michele Youket, "because there is no average disc." Back in the 1990s, historical societies, museums and symphonies across the country began transferring all kinds of information onto what was thought to be a very durable medium: the compact disc. Now, preservationists are worried that a lot of key information stored on CDs — from sound recordings to public records — is going to disappear. Some of those little silver discs are degrading, and researchers at the Library of Congress are trying to figure out why.

Traveling to enrich your life (Video)

The younger generation is choosing extended, meaningful travel experiences over standard vacations. They are redefining what travel looks like. Sarah Spagnolo, a special correspondent and new media editor at Travel + Leisure magazine, says that while young people traveling internationally is not a new trend, how they're doing it has evolved. "They're traveling internationally; they're spending more in many cases. They're looking to connect with locals and they're looking to enrich themselves," Spagnolo said. "What's new and different is this emphasis on the DIY experience, so these millennials are more accustomed to finding their own experiences online -- whether that's connecting, booking a trip, booking a restaurant reservation -- and they are taking that to the next level, so connecting with locals in different destinations."
