Smoking in US Declines to All-Time Low
Cigarette smoking has hit the lowest point ever among American adults, a new report finds. The percentage of U.S. adults who smoke cigarettes was 17.8 percent in 2013, a drop from 20.9 percent in 2005, and the lowest rate of smoking since researchers began tracking this figure in 1965, according to the report from the U.S. Centers for Disease Control and Prevention (CDC).
Many People with Dementia May Go Unscreened, Untreated
The majority of people with dementia in the United States may have never seen a doctor about their memory and thinking problems, according to a new study of older adults. The researchers found that 55 percent of patients screened for dementia as part of the University of Michigan Health and Retirement Study had never been evaluated prior to participating in this study, despite showing a clear cognitive decline. Although the study was small — it included 845 people — the results imply that upwards of 1.8 million Americans ages 70 and older with dementia also have either never been screened, or are not receiving treatment. "Early evaluation and identification of people with dementia may help them receive care earlier" and help reduce societal costs, said Dr. Vikas Kotagal, lead author on the paper and assistant professor of neurology at the University of Michigan Health System in Ann Arbor.
Welcoming the Era of In-Space Manufacturing
Mike Snyder, lead engineer for the company Made In Space, which designed and built the 3D printer currently aboard the International Space Station, contributed this article to Space.com's Expert Voices: Op-Ed & Insights. At this moment, if the space station absolutely needs a part that the 3D printer can build, I can start producing the part onboard the ISS within minutes — from my chair in California. The 3D printer can build files that are created after launch and sent to orbit when needed. Our printer is part of the NASA-funded 3D Printing in Zero-G Technology Demonstration, which is setting out to characterize the performance and demonstrate the functions of additive manufacturing in orbit.

Thanksgiving Nor'easter Seen from Space (Photos, Video)
The National Oceanic and Atmospheric Administration's weather satellites captured the beginning of the nor'easter that is expected to wreak havoc for Thanksgiving travelers today (Nov. 26) with rain and snow. The video shows another group of clouds blowing over the Northeast on Sunday (Nov. 23) and Monday, but the Thanksgiving storm starts to take shape farther south, following a curved path that dips all the way down to Mexico. The National Weather Association said in a statement that this will be a rapidly moving storm, and that most of the precipitation will fall in a 12-hour time frame. The storm is already dropping rain on Florida and will reach Canada's eastern provinces by Thanksgiving morning (Nov. 27).
Ultra-strong graphene's weak spot could be key to fuel cells
By Kate Kelland LONDON (Reuters) - In a discovery that experts say could revolutionize fuel cell technology, scientists in Britain have found that graphene, the world's thinnest, strongest and most impermeable material, can allow protons to pass through it. The researchers, led by the Nobel prize winner and discoverer of graphene Andre Geim of Manchester University, said their finding also raised the possibility that, in future, graphene membranes could be used to "sieve" hydrogen gas from the atmosphere to then generate electricity. ...
Exclusive: First gene therapy drug sets million-euro price record
By Ludwig Burger and Ben Hirschler FRANKFURT/LONDON (Reuters) - The Western world's first gene therapy drug is set to go on sale in Germany with a 1.1 million euro ($1.4 million) price tag, a new record for a medicine to treat a rare disease. The sky-high cost of Glybera, from Dutch biotech firm UniQure and its unlisted Italian marketing partner Chiesi, shows how single curative therapies to fix faulty genes may upend the conventional pharmaceutical business model. ...
Gut check: how vultures dine on rotting flesh, and like it
By Will Dunham WASHINGTON (Reuters) - They snack on danger and dine on death, merrily munching on rotting flesh that would certainly sicken or kill any person and most other animals. But how do vultures do it? These feathery scavengers have one of the toughest guts on the planet, that is how. Scientists said on Tuesday that their analysis of two species of North American vultures showed that the birds possess a ferociously acidic digestive system and intestines loaded with two fiendish kinds of bacteria. ...
Thanksgiving Science: Why Gratitude Is Good for You
Thanksgiving may be the only major American holiday focused on giving thanks for all of life's blessings, but gratitude isn't just a good excuse for chowing down on turkey and pumpkin pie; it's also a way to promote good health and well-being, experts say.
One for every leg: scientists map centipede genome
LONDON (Reuters) - An international team of more than 100 researchers has mapped the genome of the centipede and found that, while it easily outpaces humans on number of legs, it falls short when it comes to genes. Sequencing the genome of Strigamia maritima, a northern European centipede, the 106-strong team found it has around 15,000 genes - some 7,000 fewer than a human. ...
