Three people in a room with industrial equipment. Two are looking up at machines in front of them; the other is looking at the people next to him and smiling. — Curtis Hillegas (left), associate CIO of Research Computing, gave a tour of Princeton’s High-Performance Computing Research Center to formerly incarcerated students as part of a summer internship program in STEM research. Bridgett vonHoldt (center), an associate professor of ecology and evolutionary biology, directs the program; Claude McDougal (right) was one of this year’s four interns. Photos by Sameer A.

Artist rendering of biological shapes floating in a clear container — Clifford Brangwynne sees similarities between living cells and salad dressing, in which oil and vinegar separate according to the laws of physics. The idea has caught on, and now many scientists are exploring how such physical processes can play key roles in the cell’s structures, division and gene expression.
