President Amy Gutmann is cited as the chair of the Presidential Commission for the Study of Bioethical Issues.
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?

(This is the second in a series about University of Pennsylvania students who took their arguments in support of federal student financial aid to Washington this summer in a project organized by the Office of Student Registration and Financial Services. Other profiles feature students Kristin Thomas and Mounica Gummadi.)
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.
