Penn Researchers Show New Level of Control Over Liquid Crystals

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 Cares for the Feathered, the Scaly, the Slimy and the Furry at Penn Vet

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.

Penn-Led Research Suggests a New Strategy to Prevent or Halt Periodontal Disease

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.
