Chemistry team discovers new catalyst
A chemistry team at the University of Toronto has discovered environmentally-friendly iron-based nanoparticle catalysts that work as well as the expensive, toxic, metal-based catalysts that are currently in wide use by the drug, fragrance and food industry. (more…)
*Study Conducted with EXPO Shows Persuasive Elements of User-Generated Product Videos Lift Brand Affinity When Used in Tandem with Professionally-Produced Content*
NEW YORK, NY and RESTON, VA, March 28, 2012 – comScore, Inc., a leader in measuring the digital world, and EXPO, the 
first consumer network focused on creating and distributing high impact product videos to drive engagement and conversion, today released the results of a study on the synergy of professionally-produced video content and user-generated product videos in marketing campaigns. The study evaluated an actual campaign that included a combination of a professionally-produced “how to” video and a user-generated product video that was created and submitted by an actual product user. The results of the study indicate that professionally-produced video content and user-generated product videos are highly synergistic, driving higher levels of sales effectiveness when used in tandem.

Researchers at Brown University and Hasbro Children’s Hospital have traced the molecular interactions that allow the protein survivin to escape the nucleus of a breast cancer cell and prolong the cell’s life. The study may help in the development of better therapies and prognostics
PROVIDENCE, R.I. [Brown University] — If the fight against breast cancer were a criminal investigation, then the proteins survivin, HDAC6, CBP, and CRM1 would be among the shadier figures. In that vein, a study to be published in the March 30 Journal of Biological Chemistry is the police report that reveals a key moment for keeping cancer cells alive: survivin’s jailbreak from the nucleus, aided and abetted by the other proteins. The research highlights that a protein’s location in a cell affects its impact on disease, and offers clear new leads for the investigation. (more…)
Among terrorism scenarios that raise the most concern are attacks involving nuclear devices or materials. For that reason, technology that can effectively detect smuggled radioactive materials is considered vital to U.S. security. (more…)
In a study in The New England Journal of Medicine, authors including biostatisticians from Brown report that coronary computed tomographic angiography (CCTA) is a safe way to screen patients coming to the ER with chest pains who are not at high risk for acute coronary syndrome. Patients who got CCTA and tested negative were more likely to be discharged home and spend less time at the hospital.
Coronary computed tomographic angiography (CCTA), a technology for diagnostic imaging of the heart, is a safe way to assess whether patients whose risk of heart attack is not high need to be hospitalized when they arrive at the emergency room complaining of chest pains. Brown biostatisticians led by Constantine Gatsonis are part of a team of researchers who report that finding in The New England Journal of Medicine and at the American College of Cardiology Conference March 26.

Professor creates mini-musical celebrating video website
Joyce Hill Stoner, the Edward F. and Elizabeth Goodman Rosenberg Professor of Material Culture in the University of Delaware’s Department of Art Conservation, is an internationally respected scholar and paintings conservator who has a flair for showmanship as well.
Her latest entertainment production, an eight-minute musical in which the state of Delaware salutes YouTube, now is posted on that site for the world to see. Live for just a couple of days, the video already has attracted thousands of viewers. (more…)
A group of scientists from Hawaiʻi, Brazil and California has measured the diameter of the Sun with unprecedented accuracy by using a spacecraft to time the transits of the planet Mercury across the face of the Sun in 2003 and 2006.
The measurements of the Sun’s size were made by University of Hawaiʻi at Mānoa Institute for Astronomy scientists Drs. Marcelo Emilio (visiting from Ponta Grossa, Brazil), Jeff Kuhn and Isabelle Scholl in collaboration with Dr. Rock Bush of Stanford University. They used the Michelson Doppler Imager (MDI) aboard NASA’s Solar and Heliospheric Observatory (SOHO) to make the measurements. (more…)
*Youths echo findings from International Youth Foundation report, which urges actions to help young people succeed.*
REDMOND, Wash. — March 27, 2012 — The numbers are staggering: Our planet has the largest youth population ever, with more than 1 billion people aged 15 to 24, and the figure is racing to 1.5 billion by 2035, according to “Opportunity for Action,” a new report being released today from the International Youth Foundation (IYF). The report shows that while some youths are succeeding, millions of others are not because they don’t have access to the necessary education, skills and opportunities.
Microsoft commissioned the “Opportunity for Action” report to bring attention to the urgency of the global youth opportunity divide — the gap between those who have access to a good education and the technology, skills and connections to be successful, and those who do not. No region of the world escapes the unsettling picture captured by the report. In Brazil, approximately 40 percent of firms have difficulty finding qualified staff to fill job vacancies due to low-quality education. In Asia, 70 percent of working youths are engaged in the agricultural sector, where jobs are seasonal and offer no protections or access to safety nets. And in sub-Saharan Africa, youths are grossly under-employed, leaving 72 percent of young people living on less than two dollars per day. (more…)
