PHILADELPHIA — As the world’s accessible oil reserves dwindle, natural gas has become an increasing important energy source. The primary component of natural gas is methane, which has the advantage of releasing less carbon dioxide when it’s burned than do many other hydrocarbon fuels. But because of the very stable structure of the methane molecule, it can be difficult to access the energy stored within.
PHILADELPHIA – Charles L. Kane of the University of Pennsylvania is among three who have been awarded the 2012 Dirac Medal and Prize by the Abdus Salam International Centre for Theoretical Physics.
PHILADELPHIA — Many recent advances in microtechnology and nanotechnology depend on microscopic spherical particles self-assembling into large-scale aggregates to form a relatively limited range of crystalline structures. Directed assembly is a new branch of this field, where scientists figure out how to make particles assemble to form a broad range of structures at given locations.

PHILADELPHIA — Human diversity in Africa is greater than any place else on Earth. Differing food sources, geographies, diseases and climates offered many targets for natural selection to exert powerful forces on Africans to change and adapt to their local environments. The individuals who adapted best were the most likely to reproduce and pass on their genomes to the generations who followed.
Many Protected Areas Face Threats in Sustaining Biodiversity, Penn’s Daniel Janzen and Colleagues Report
PHILADELPHIA — Establishing protection over a swath of land seems like a good way to conserve its species and its ecosystems. But in a new study, University of Pennsylvania biologist Daniel Janzen joins more than 200 colleagues to report that protected areas are still vulnerable to damaging encroachment, and many are suffering from biodiversity loss.
