The aging of star clusters is linked more with their lifestyle than with how old they actually are, according to a new NASA/ESA Hubble Space Telescope study coauthored by Steinn Sigurdsson, professor of astronomy and astrophysics at Penn State. "Our observations of star clusters have shown us that, although they all formed over ten billion years ago, some of them are still young at heart," Sigurdsson said.

The discovery that hundreds of stars are rapidly moving together in long, looping orbits around the center of our Galaxy has been announced by a team of scientists including a Penn State University astronomer and others collaborating in the Sloan Digital Sky Survey III (SDSS-III). "The stars near the nucleus of the Milky Way appear to form a bar-like structure thousands of light years in size," said Donald Schneider, a Distinguished Professor of Astronomy and Astrophysics at Penn State and a coauthor of the study. "In this investigation, we were able to accurately measure the motions of a set of stars located in the Galaxy's bar and to gain some insight into the dynamics of the central, dense regions of the Milky Way." Schneider is the Survey Coordinator and Scientific Publications Coordinator for the SDSS-III.
"Your Genes: How they contribute to who you are" is the theme of the 2013 Penn State Lectures on the Frontiers of Science, which will take place in January and February 2012.
Aleksandra Slavkovic, an associate professor of statistics and public health sciences at Penn State University, has been honored with membership in the International Statistical Institute. Members are elected "by virtue of their distinguished contributions to the development or application of statistical methods, or to the administration of statistical services, or the development and improvement of statistical education."
Yingwei Mao, an assistant professor of biology at Penn State University, has been honored with a National Scientist Development Grant from the American Heart Association. The grant supports highly promising beginning scientists in their progress toward independence by encouraging and adequately funding research projects that can bridge the gap between completion of research training and readiness for successful competition as an independent investigator.
Andrew F. Read, the Alumni Professor in the Biological Sciences and a professor of entomology at Penn State University, has been named a Fellow of the American Association for the Advancement of Science (AAAS). Election as an AAAS Fellow is an honor bestowed by peers upon members of the AAAS, the world's largest general scientific society and the publisher of the journal Science.
Peter J. Hudson, the Willaman Chair in Biology at Penn State University, has been named a Fellow of the American Association for the Advancement of Science (AAAS). Election as an AAAS Fellow is an honor bestowed by peers upon members of the AAAS, the world's largest general scientific society and the publisher of the journal Science.
Nitin Samarth, a professor of physics at Penn State University and the George A. and Margaret M. Downsbrough Head of the Department of Physics, has been named a Fellow of the American Association for the Advancement of Science (AAAS). Election as an AAAS Fellow is an honor bestowed by peers upon members of the AAAS, the world's largest general scientific society and the publisher of the journal Science.
For the first time, a silicon-based optical fiber with solar-cell capabilities has been developed that has been shown to be scalable to many meters in length. The research opens the door to the possibility of weaving together solar-cell silicon wires to create flexible, curved, or twisted solar fabrics. The findings by an international team of chemists, physicists, and engineers, led by John Badding, a professor of chemistry at Penn State University, will be posted by the journal Advanced Materials in an early online edition on 6 December 2012 and will be published on a future date in the journal's print edition.
Yingwei Mao, an assistant professor of biology at Penn State University, has been honored with a NARSAD Young Investigator Grant. The award provides support for the most promising young scientists conducting neurobiological research.
A new paradigm for understanding the earliest eras in the history of the universe has been developed by scientists at Penn State University. Using techniques from an area of modern physics called loop quantum cosmology, developed at Penn State, the scientists now have extended analyses that include quantum physics farther back in time than ever before -- all the way to the beginning.
Penn State University Waller Professor of Plant Biology and past President of the American Society of Plant Biologists Sarah M. Assmann is the invited author of the inaugural Coulter Review article to be published in the January 2013 issue of the International Journal of Plant Sciences. A world leader in the field of plant-cell signal transduction, Assmann studies plant genetics and how plants receive and respond to stimuli from the environment.
By examining art printed from woodblocks spanning five centuries, Blair Hedges, a professor of biology at Penn State University, has identified the species responsible for making the ever-present wormholes in European printed art since the Renaissance. The hole-makers, two species of wood-boring beetles, are widely distributed today, but the "wormhole record," as Hedges calls it, reveals a different pattern in the past, where the two species met along a zone across central Europe like a battle line of two armies.
The adverse side effects of certain hepatitis C medications can now be replicated and observed in Petri dishes and test tubes, thanks to a research team led by Craig Cameron, the Paul Berg Professor of Biochemistry and Molecular Biology at Penn State University. "The new method not only will help us to understand the recent failures of hepatitis C antiviral drugs in some patients in clinical trials," said Cameron. "It also could help to identify medications that eliminate all adverse effects."
Donald A. Bryant, the Ernest C. Pollard Professor of Biotechnology at Penn State University, has been elected by the Fellows of the American Academy of Microbiology (AAM) to the Board of Governors. The three-year term is an elected position that is voted upon by the membership of AAM, the honorific arm of the American Society for Microbiology.
Benjamin Lear, an assistant professor of chemistry at Penn State University, was awarded a 3M Nontenured Faculty Grant. This award, which is administered by 3M Research and Development in partnership with the Corporate Giving Program, recognizes outstanding new faculty. It is intended to help young faculty members to achieve tenure, to teach, and to conduct research.
Richard Villanti to Represent Penn State's Eberly College of Science as Student Marshal at Fall Commencement 2012
Richard Villanti of Sayre, Pennsylvania will be honored as the student marshal for the Eberly College of Science during Penn State University's fall commencement ceremonies on 22 December, 2012, at the University Park campus. Villanti's faculty escort for the commencement exercises will be Diane Henderson, a professor of mathematics.
The Great Space Coaster: Expansion of the Universe Now Measured in an Era before Dark Energy Takes Over
For the past five-billion years, the expansion of the universe has been powered by a mysterious repulsive force known as "dark energy." Now, thanks to a new technique for measuring the three-dimensional structure of the distant universe, scientists in an international team within the Sloan Digital Sky Survey (SDSS-III), including an astronomer at Penn State University, have made the first measurement of the rate of this cosmic expansion as it was just three-billion years after the Big Bang.
