art/sci update February 2013: Researcher seeks to understand why hip and knee replacements fail

Posted on February 15, 2013


Researcher seeks to understand why replacement hips and knees fail

Anna C. Samia, an assistant professor in the Department of Chemistry, is leading a study investigating why artificial joints deteriorate. Each year, 40,000 Americans undergo surgery to have worn-out knee or hip implants replaced.

Samia, who specializes in metallic nanostructures, has been awarded a five-year, $600,000 National Science Foundation-CAREER grant to create new materials and equipment to test the plastic used to make artificial joints. By imbedding magnetic nanoparticles in the implants, her research team will be able to image them and monitor their degradation over time. Read more.

Astronomers find new galaxy, possible protogalaxy

A team of researchers led by Chris Mihos, chair of the Department of Astronomy, has found a faint dwarf galaxy and what may be one of the first known protogalaxies. Surveying galaxy M101 and gas clouds that surround it, the astronomers found what may be the first starless gas cloud that is not associated with a larger galaxy. If confirmed, it would be a true protogalaxy—one that might not develop stars for millions or billions of years.

The findings, reported in two papers published in the Astrophysical Journal, were made possible by reconfiguring the university’s Burrell Schmidt wide-field telescope. Read more.

Study finds online connectivity benefits older adults

Psychologist T. J. McCallum reports that older adults who learn to surf the Internet, email, post pictures and use technology to stay connected feel uplifted and generally more fulfilled.

In his study “The Impact of Tablet Usage on Social Engagement among Older Adults,” 25 senior citizens with no prior technology experience received a computer tablet and training. After three months of use, the group showed improvements in problem solving, computer-driven social engagement and optimism as compared to a control group. Read more.

Is it possible to create an artistic work whose impact never fades?

What if every time you heard a song or read a book, it felt like the first time? Of course, that may not be possible; repeating an experience tends to dull its impact.

Michael W. Clune, assistant professor in the Department of English, writes about artists who hope to achieve immortality by creating works that provide “unfading freshness.” An essay adapted from his recently published book, Writing Against Time, appears in The Chronicle of Higher Education.

Undergraduate student works to aid Zambian girls’ education

Last summer, senior Mai Segawa traveled to Zambia and the UN Refugee Agency’s Meheba Refugee Camp, where she saw the safety and inequality issues that prevent young women from receiving their education.

Now, in hopes of building a girls’ study center in Zambia, she’s entered Dell’s Social Innovation Challenge. Read more and learn how you can help her effort before the Feb. 18 deadline.
