Graphene, a material that consists of a lattice of carbon atoms, one atom thick, is widely touted as being the most electrically conductive material ever studied. However, not all graphene is the same. With so few atoms comprising the entirety of the material, the arrangement of each one has an impact on its overall function.
A team of scientists and physicians at the University of Pennsylvania will lead a four-year effort worth as much as $22.5 million to develop next-generation technologies to restore memory function in people who suffer from memory loss due to disease or traumatic injury.
The Field Center for Children’s Policy, Practice & Research at the University of Pennsylvania welcomed a group of students from South Korea’s Namseoul University to campus for an inaugural three-week summer program illustrating how child welfare is practiced in the United States.
For the last century, the concept of crystals has been a mainstay of solid-state physics. Crystals are paragons of order; crystalline materials are defined by the repeating patterns their constituent atoms and molecules make.
Hosted within the Barbara and Edward Netter Center for Community Partnerships at the University of Pennsylvania, the International Consortium for Higher Education, Civic Responsibility and Democracy will play a major role in a global forum focused on democracy June 25-27 in Belfast, Nor
Angiogenesis, the sprouting of new blood vessels from pre-existing ones, is essential to the body’s development. As organs grow, vascular networks must grow with them to feed new cells and remove their waste. The same process, however, also plays a critical role in the onset and progression of many cancers, as it allows the rapid growth of tumors.
On June 24, David Hewitt, a biologist and lecturer at the University of Pennsylvania, will give a Penn Science Cafe talk titled, “Cities aren’t like ecosystems, they are ecosystems.”
Penn Science Café series lecture and discussion, “Cities aren’t like ecosystems, they are ecosystems”
Tuesday, June 24, 6-7 p.m.
World Cafe Live Upstairs, 3025 Walnut St.
During the past two years, David Hewitt has taught ecology to students of City & Regional Planning. This talk will be a "lessons learned" from that experience: about how and why one should understand cities as ecosystems — not as a metaphor, not as stretch of the imagination, but simply and clearly as ecosystems governed by ecological principles, just as other kinds of ecosystems are.
The talk is part of the Penn Science Café free public-lecture series presented by the School of Arts & Sciences and the Office of University Communications that takes science out of the lab for a night on the town. Hewitt’s presentation will be followed by an audience Q&A.
Food and beverages will be available for purchase. Seating is limited.
