John McWhorter may be best known for his magazine and newspaper writing about race, but the Philadelphia native is at heart a dyed-in-the-wool academic whose first inkling that he would spend his life studying languages came when he was still a preschooler and heard someone speaking a fore

A digital microarray from the lab of Ken Shepard, a professor of electrical engineering, can measure individual DNA molecules, which are shown in this image. The new technology dramatically improves and simplifies genetic analysis.
Ken Shepard, a professor of electrical engineering, believes there is nowhere else in the world where he could do what he does. “Imagine a convergence of semiconductor technology and biotechnology. There is no company out there that has expertise in both,” he says.

It’s relatively simple to build a device capable of detecting wireless signals if you don’t mind making one that consumes lots of power. It’s not so easy to design energy-efficient devices that function as well as the components they replace, or to do it at the nano scale.
Jim Yardley has seen firsthand how the nanotechnology field has exploded over the past decade. “It’s extremely exciting,” says the managing director of Columbia’s Nanoscale Science and Engineering Center.
