PHILADELPHIA — The University of Pennsylvania’s Laboratory for Research on the Structure of Matter has been awarded a six-year, $21.7 million center grant from the National Science Foundation to support LRSM’s work in cutting-edge materials.
PHILADELPHIA -- A research team led by Marija Drndić of the University of Pennsylvania has been awarded a three-year, $1.5 million grant to apply nanotechnology and materials science to the development of “third generation” techniques for DNA sequencing and to lower the cost of sequencing.
The grant was made by the National Human Genome Research Institute, part of the National Institutes of Health.
PHILADELPHIA — In an effort to better understand sea-level rise and flooding from hurricanes along the Atlantic and Gulf coasts, the National Oceanic and Atmospheric Administration has awarded a three-year, $1.5 million grant to a research team led by the University of Pennsylvania’s Benjamin Horton. The study aims to provide predictive models and reports that can be used both by environmental scientists and coastal communities.
Rob Kurzban of the School of Arts and Sciences comments on the Dunning-Kruger effect.
PHILADELPHIA — In solid materials with regular atomic structures, figuring out weak points where the material will break under stress is relatively easy. But for disordered solids, like glass or sand, their disordered nature makes such predictions much more daunting tasks.
Arjun Yodh and student Peter Yunker of the School of Arts and Sciences discuss the “coffee ring effect.”
PHILADELPHIA — It is helpful — even life-saving — to have a warning sign before a structural system fails, but, when the system is only a few nanometers in size, having a sign that’s easy to read is a challenge. Now, thanks to a clever bit of molecular design by University of Pennsylvania and Duke University bioengineers and chemists, such warning can come in the form of a simple color change.
