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…)

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.

The answer, according to Ram’s research, varies widely by news agency, and there may not be one universally applicable strategy for maximizing Twitter effectiveness. However, news agencies can learn a lot by looking at how their news diffuses once it is posted on Twitter, said Ram, McClelland Professor of Management Information Systems in the UA’s Eller College of Management.

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…)

Katherine Boo talks of hope and struggle in Annawadi, India

Pulitzer Prize-winning author Katherine Boo found that despite having to struggle daily to survive, the people who live in Annawadi, India, also share the common hopes, dreams and aspirations of people everywhere in seeking to better themselves and their children.

Boo, the author of Behind the Beautiful Forevers: Life, Death and Hope in a Mumbai Undercity, shared her experiences as a journalist reporting from the Mumbai slum during a 2012 University of Delaware First Year Common Reader program presentation held Wednesday, Oct. 10, in Mitchell Hall. (more…)

The Best of Both Catalytic Worlds

Berkeley Lab Researchers Develop New Technique for Heterogenizing Homogenous Nano Catalysts

Catalysts are substances that speed up the rates of chemical reactions without themselves being chemically changed. Industrial catalysts come in two main types – heterogeneous, in which the catalyst is in a different phase from the reactants; and homogeneous, in which catalyst and the reactants are in the same phase. Heterogeneous catalysts are valued for their sustainability because they can be recycled. Homogeneous catalysts are valued for their product selectivity as their properties can be easily tuned through relatively simple chemistry.

Researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) have combined the best properties of both types of industrial catalysts by encapsulating nanoclusters of a metallic heterogeneous catalyst within the branched arms of the molecules known as dendrimers.

Freezing Electrons in Flight

Using the world’s fastest laser pulses, which can freeze the ultrafast motion of electrons and atoms, UA physicists have caught the action of molecules breaking apart and electrons getting knocked out of atoms. Their research helps us better understand molecular processes and ultimately be able to control them in many possible applications.

In 1878, a now iconic series of photographs instantly solved a long-standing mystery: Does a galloping horse touch the ground at all times? (It doesn’t.) The images of Eadweard Muybridge taken alongside a racetrack marked the beginning of high-speed photography.

Approximately 134 years later, researchers in the University of Arizona department of physics have solved a similar mystery, one in which super-excited oxygen molecules have replaced the horse, and ultrafast, high-energy laser flashes have replaced Muybridge’s photo emulsion plates. (more…)

Researchers around the world are working on an efficient, reliable way to contain the plasma used in fusion reactors, potentially bringing down the cost of this promising but technically elusive energy source. A new finding from the University of Washington could help contain and stabilize the plasma using as little as 1 percent of the energy required by current methods.

“All of a sudden the current energy goes from being almost too much to almost negligible,” said lead author Thomas Jarboe, a UW professor of aeronautics and astronautics. He presents the findings this week at the International Atomic Energy Association’s 24^th annual Fusion Energy Conference in San Diego. (more…)

ANN ARBOR — One of the casualties of the 1994 Rwandan genocide was the culture’s storytelling tradition. Resurrecting it has been the mission of a project called Stories for Hope for the past four years.

Now 99 narratives—conversations between youths and elders—will go on exhibit at the newly built Rwandan National Archives, which were decimated during the violence. On Oct. 12, the archives open again for the first time in nearly two decades. (more…)
