Peter Dodson of the School of Veterinary Medicine is quoted about studying species that were misclassified.
Daniel Janzen and Winnie Hallwachs of the School of Arts and Sciences are highlighted for their insect research and collecting in Costa Rica.
Both basic scientists and clinicians have an interest in how the cells of our body move. Cells must be mobile in order for organisms to grow, to heal, to transmit information internally, to mount immune responses and to conduct a host of other activities necessary for survival.
A new analysis of dinosaur fossils by University of Pennsylvania researchers has revealed that a number of specimens of the genus Psittacosaurus — once believed to represent three different species — are all members of a single species.
Arjun Yodh of the School of Arts and Sciences co-authors a blog post about studying stuttering.
When University of Pennsylvania nanoscientists created beautiful, tiled patterns with flat nanocrystals, they were left with a mystery: why did some sets of crystals arrange themselves in an alternating, herringbone style, even though it wasn’t the simplest pattern?

Physicist Charlie Johnson connects the biological to the digital, using graphene and carbon nanotubes to turn chemical interactions into electrical signals. Johnson will explain how attaching biological structures, such as antibodies, to these flat or rolled-up lattices of carbon atoms has enabled him and his colleagues to build new kinds of sensors, detecting things like Lyme disease bacteria.
Catalysts are everywhere. They make chemical reactions that normally occur at extremely high temperatures and pressures possible within factories, cars and the comparatively balmy conditions within the human body. Developing better catalysts, however, is mainly a hit-or-miss process.
