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.
Student Andrea Spaeth of the School of Arts and Sciences is quoted about her research on the connection between sleep duration and weight gain.
The inner workings of a cell involve hundreds of thousands of discrete molecules, engaged in a repeating cycle of interactions that sustain life.
The University of Pennsylvania has been named a project site for the Undergraduate STEM Education Initiative, a multiyear, multimillion dollar project that aims to improve the quality of education in science, technology, engineering and mathematics.
