A fuzzy concept: Scientists turned to nature to solve a high-tech problem.

Instrumental: Computer scientist Pedro Lopes integrates technology with anatomy to reimagine the role of “human” in human-computer interaction.

By the dozens: Microbiologist Maurice Hilleman, PhD’44, and his feathered friends.

A wider scope: Nancy Grace Roman, PhD’49, didn’t get tenure. She changed the course of astronomy instead.

Data mind: Computer scientists Heather Zheng, Ben Zhao, and Blase Ur mine data to study behavior and expose security flaws.

The other one: Twins Laurie and Lynne Butler—one a UChicago chemistry professor, the other a double alumna—discuss math, horses, and a college boyfriend who never got them confused.
