Bijels, or bicontinuous interfacially jammed emulsion gels, are structured emulsions of oil and water that are kept separated by a layer of nanoparticles. Penn Engineering researchers will develop a way of using them to manufacture mRNA-based therapeutics. (Image: Penn Engineering Today)

In Asian American studies classrooms, “you get students from every single major, you get them from every single field, you get every class background, and you get every political background,” says David Eng. “What’s happened in the field of ethnic studies in general, is that you’ve had to create these horizontal communities among these generations of students.”

A suspension of particles of different sizes during shearing experiments conducted in the lab of Paulo Arratia, with arrows indicating particle “flow” and trajectories. In a new study published in Nature Physics, researchers detail the relationship between a disordered material’s individual particle arrangement and how it reacts to external stressors. The study also found that these materials have “memory” that can be used to predict how and when they will flow. (Image: Arratia lab)

In a controlled field experiment on Penn’s campus, biologists tracked fruit fly evolution over the course of four months, documenting some of the fastest rates of adaptation ever in animals. (Image: Seth Rudman)
