Kepler's Supernova came from young, metal-rich star, researchers discover
The supernova observed by Johannes Kepler in 1604, known as “Kepler’s supernova,” came from a relatively young star that was rich in metals, according to research published by The Astrophysical Journal Letters and co-authored by Sangwook Park, assistant professor of physics.
The new work expands upon what’s already known about Type Ia supernovae—stellar explosions used to calibrate theories about the expansion of our universe. The study is featured on the NASA website.
Dr. Park along with Carles Badenes, an assistant professor of physics and astronomy at the University of Pittsburgh, and their collaborators set out to use X-ray observation data from the Japanese/United States Suzaku Observatory to further explore Type Ia progenitors and how they explode.
“Even with all that is known about the universe and its expansion, there are still some systematic uncertainties in the way Type Ia supernovae are used,” Park says. “If we can get a better idea about those uncertainties, it will make a significant contribution to improve the accuracy of the distance measurements for galaxies far away from our own Milky Way Galaxy. It also would likely contribute to the understanding of the acceleration of the universe’s expansion and the role of dark energy.”

Motor skills research good news for middle-aged
People in their 20s don’t have much on their middle-aged counterparts when it comes to some fine motor movements, according to Priscila Caçola, assistant professor of kinesiology.
In a simple finger-tapping exercise, study participants’ speed declined only slightly with age until a marked drop in ability with participants in their mid-60s.
Dr. Caçola hopes the new work will help clinicians identify abnormal loss of function in their patients. Though motor ability in older adults has been studied widely, little research has focused on when deficits begin, she says.
The journal Brain and Cognition will include the study in its June 2013 issue. It is already available online.
“We have this so-called age decline, everybody knows that. I wanted to see if that was a gradual process,” Caçola says. “It’s good news really because I didn’t see differences between the young and middle-aged people.”
Co-authors on the paper are Jerroed Roberson, kinesiology senior, and Carl Gabbard, a professor in the Texas A&M University Department of Health and Kinesiology.

University to offer online programs in Latin America
Beginning in May, UT Arlington will offer five certificate programs to Latin American, post-secondary students, including a new Certificate in Public Health, in partnership with the Ilumno Network.

Enrollment is open through May 12 at hechoparaliderar.com.
“Our Public Health certificate program is specifically designed to be culturally relevant and to address community health needs in Latin America,” says Elizabeth C. Poster, dean of the College of Nursing. “The courses are designed to improve community health outcomes and to provide our students knowledge that is important for social mobility.”
The Ilumno Network is composed of 10 higher education institutions in Argentina, Brazil, Chile, Colombia, Costa Rica, Panama, Paraguay, and Peru with more than 260,000 students and alumni. Students enrolled in the certificate programs will complete four five-week courses using UT Arlington certificate curricula delivered in Spanish, with permanent instructional support from Ilumno Network faculty.
