PHILADELPHIA — Though churning smokestacks, cud-chewing cows and gasoline-burning vehicles are contributing constantly to greenhouse gas emissions, there are also many processes that do the reverse, pulling molecules like carbon dioxide out of the atmosphere. One of these is chemical weathering, which occurs when rock turns into soil.
PHILADELPHIA — Directed assembly is a growing field of research in nanotechnology in which scientists and engineers aim to manufacture structures on the smallest scales without having to individually manipulate each component. Rather, they set out precisely defined starting conditions and let the physics and chemistry that govern those components do the rest.
La’Toya Latney’s grandmother has a photo from when Latney was about 5 years old. In it, she is sitting in front of the television, transfixed by a nature program on grizzly bears hunting salmon swimming upstream. “At that time she said she knew I was going to be a veterinarian, so it’s been a long time coming for me,” says Latney.
Liquid crystals have become a workhorse of technology; they are the standard for television and computer displays. In fact, there is a good chance you are looking at some liquid crystals right now.
PHILADELPHIA — The field of metamaterials involves augmenting materials with specially designed patterns, enabling those materials to manipulate electromagnetic waves and fields in previously impossible ways.
PHILADELPHIA — Learning calculus is no easy feat.
PHILADELPHIA — In the waning days of 2012, two words have dominated the post-election discourse: “fiscal cliff.” The cliff is a combination of impending budgetary measures that will take effect in January if a legislative compromise is not reached.
PHILADELPHIA — Periodontitis, a form of chronic gum disease that affects nearly half of the U.S. adult population, results when the bacterial community in the mouth becomes unbalanced, leading to inflammation and eventually bone loss. In its most severe form, which affects 8.5 percent of U.S. adults, periodontitis can impact systemic health.
PHILADELPHIA – Five faculty members at the University of Pennsylvania have been named Fellows of the American Association for the Advancement of Science. Two are from Penn’s Perelman School of Medicine, two are from its School of Arts and Sciences
