Graphene Membranes May Lead To Enhanced Natural Gas Production, Less CO2 Pollution, Says CU Study

Engineering faculty and students at the University of Colorado Boulder have produced the first experimental results showing that atomically thin graphene membranes with tiny pores can effectively and efficiently separate gas molecules through size-selective sieving.

The findings are a significant step toward the realization of more energy-efficient membranes for natural gas production and for reducing carbon dioxide emissions from power plant exhaust pipes.

Mechanical engineering professors Scott Bunch and John Pellegrino co-authored a paper in Nature Nanotechnology with graduate students Steven Koenig and Luda Wang detailing the experiments. The paper was published Oct. 7 in the journal’s online edition. (more…)

Armchair Astronomers Find Planet in Four-Star System

A joint effort of citizen scientists and professional astronomers has led to the first reported case of a planet orbiting twin suns that in turn is orbited by a second distant pair of stars.

Aided by volunteers using the Planethunters.org website, a Yale-led international team of astronomers identified and confirmed discovery of the phenomenon, called a circumbinary planet in a four-star system.

Only six planets are known to orbit two stars, according to researchers, and none of these are orbited by distant stellar companions. (more…)

Fingerprints for Financing: Removing Some Risk from Lending in Africa

ANN ARBOR — Some called it “witchcraft.” Others just watched in awe as their scanned fingerprints were used to pull up their records on a computer.

They were paprika farmers in Malawi participating in a new study that shows fingerprinting can help encourage borrowers to repay their loans.

Like many impoverished countries, Malawi lacks a national identification system. Most of the population lives in rural areas with few government services. Even ID as basic as a birth certificate is rare in the southeastern African nation. (more…)

Gold Nanoparticle Prostate Cancer Treatment Found Safe in Dogs, MU Study Shows

New treatment may have fewer side effects than traditional cancer therapy

COLUMBIA, Mo. ­— Currently, large doses of chemotherapy are required when treating certain forms of cancer, resulting in toxic side effects. The chemicals enter the body and work to destroy or shrink the tumor, but also harm vital organs and drastically affect bodily functions. Now, scientists at the University of Missouri have proven that a new form of prostate cancer treatment that uses radioactive gold nanoparticles, and was developed at MU, is safe to use in dogs. Sandra Axiak-Bechtel, an assistant professor in oncology at the MU College of Veterinary Medicine, says that this is a big step for gold nanoparticle research.

“Proving that gold nanoparticles are safe to use in the treatment of prostate cancer in dogs is a big step toward gaining approval for clinical trials in men,” Axiak-Bechtel said. “Dogs develop prostate cancer naturally in a very similar way as humans, so the gold nanoparticle treatment has a great chance to translate well to human patients.” (more…)

Meet Xbox Music, Microsoft’s New All-in-One Music Service

Xbox Music is Microsoft’s brand new all-in-one music service that enables users to listen to music how, when, where and on what device they want. It is included in a rolling update to Xbox LIVE that starts Tuesday and will be expanded when Windows 8 launches.

REDMOND, Wash. Oct. 14, 2012 — If music makes the people come together, as Madonna says, the new Xbox Music gives people all the music they love, every way they want it.

Xbox Music, Microsoft’s new all-in-one music service, specially designed to let users listen to music in exactly the way they want, begins rolling out to millions of people around the world Oct. 16 on the Xbox 360, then to the masses with Windows 8 on Oct. 26. (more…)

UA Study Examines How News Spreads on Twitter

A study of the Twitter activity of 12 major news agencies shows varying levels of success for the social network as a news-sharing tool, based on factors like article lifespan and number of retweets

Nearly every major news organization has a Twitter account these days, but just how effective is the microblogging website at spreading news? That’s the question University of Arizona professor Sudha Ram set out to answer in a recent study of a dozen major news organizations that use the social media website as one tool for sharing their content.

Football Scores a Health Hat Trick for Hypertensive Men

Playing football (soccer) could be the best way for people with high blood pressure, known as hypertension, to improve their fitness, normalise their blood pressure and reduce their risk of stroke, according to research published today (Monday 15 October 2012) in the journal Medicine and Science in Sports and Exercise.

Research from Universities of Exeter and Copenhagen, and Gentofte University Hospital in Denmark suggests football training prevents cardiovascular disease in middle-aged men with hypertension and is more effective than healthy lifestyle advice currently prescribed by GPs.

After six months of football training, three out of four men in this study had blood pressure within the normal, healthy range. (more…)

Engineered Flies Spill Secret of Seizures

Scientists have observed the neurological mechanism behind temperature-dependent — febrile — seizures by genetically engineering fruit flies to harbor a mutation analogous to one that causes epileptic seizures in people. In addition to contributing the insight on epilepsy, their new study highlights the first use of genetic engineering to swap a human genetic disease mutation into a directly analogous gene in a fly.

PROVIDENCE, R.I. [Brown University] — In a newly reported set of experiments that show the value of a particularly precise but difficult genetic engineering technique, researchers at Brown University and the University of California–Irvine have created a Drosophila fruit fly model of epilepsy to discern the mechanism by which temperature-dependent seizures happen.
