Mark Devlin of the School of Arts and Sciences is interviewed about astronomy and new documentary “B.L.A.S.T.!”
PHILADELPHIA -- A new mathematical model developed by researchers at the University of Pennsylvania has offered even more evidence of the correctness of evolutionary theory.
Herbert Wilf, Penn’s Thomas A. Scott Emeritus Professor of Mathematics, and Warren Ewens, emeritus professor of biology, say their model directly challenges the long-standing contention among some doubters that evolution couldn't have happened because the small changes in species outlined by the theory simply would have taken too much time to be completed.
PHILADELPHIA –- A new instrument designed, built and operated by a collaboration including University of Pennsylvania astronomer James Aguirre and scientists at the California Institute of Technology, the Jet Propulsion Laboratory, the University of Colorado and Japan's Institute of Space and Astronautical Science, is helping to open new views on a vital epoch of star formation in the early universe, using a convenient natural phenomenon called gravitatio
PHILADELPHIA – Christopher S. Chen has been named the recipient of the 2010-11 George H. Heilmeier Faculty Award for Excellence in Research in the School of Engineering and Applied Science at the University of Pennsylvania.
Chen is the Skirkanich Professor of Innovation in the Department of Bioengineering. He is also a faculty member of the Cell Biology and Physiology Program as well as the Cell Growth and Cancer Program, director of the Tissue Microfabrication Laboratory and founding director of the Center for Engineering Cells and Regeneration.
PHILADELPHIA –- Researchers at the University of Pennsylvania report that a new test for measuring the ability of gravity to bend light seen from distant stars around large objects like black holes may offer proof of the existence of extra dimensions in the universe.
PHILADELPHIA -– Researchers at the University of Pennsylvania have developed a new electronic method for detecting microRNA isolated from living cells. MicroRNAs are a class of small biomolecules that control gene expression into proteins, the “workers” of the cell. MicroRNAs act by binding to specific messenger RNAs that code for proteins, and, by doing so, inhibit protein synthesis.
PHILADELPHIA –- A fossil found more than 150 years ago has now been identified as the remains of a new species of dinosaur, the herbivore Kukufeldia tigatensis. The study was led by University of Pennsylvania graduate student Andrew McDonald and paleontologists from the Natural History Museum, London.
