Amanda Randles wants to copy your body. If the computer scientist had her way, she’d have enough data — and processing power — to effectively clone you on her computer, run the clock forward, and see what your coronary arteries or red blood cells might do in a week. Fully personalized medical simulations, or “digital twins,” are still beyond our abilities, but Randles has pioneered computer models...

The phrase “hand-wavy” is a favorite, and if she mentions “meaning” or “reasoning,” it’ll often come with conspicuous air quotes. This is just Pavlick’s way of keeping herself honest. As a computer scientist studying language...

In Cassandra Extavour’s office at Harvard University hangs a placard with a painted rainbow flag and a friendly invitation. “You are welcome here,” it reads. “I have it up because I think it’s important to let people see your identities, especially when those identities are not well represented,” explained Extavour, an evolutionary geneticist who in 2014 became the first Black woman to win tenure...
