Ah, the world! Oh, the world!
—“Moby-Dick.”
David Gruber began his almost impossibly varied career studying blue-striped grunt fish off the coast of Belize. He was an undergraduate, and his job was to track the fish at night. He navigated by the stars and slept in a tent on the beach. “It was a dream,” he recalled recently. “I didn’t know what I was doing, but I was performing what I thought a marine biologist would do.”
Gruber went on to work in Guyana, mapping forest plots, and in Florida, calculating how much water it would take to restore the Everglades. He wrote a Ph.D. thesis on carbon cycling in the oceans and became a professor of biology at the City University of New York. Along the way, he got interested in green fluorescent proteins, which are naturally synthesized by jellyfish but, with a little gene editing, can be produced by almost any living thing, including humans.
While working in the Solomon Islands, northeast of Australia, Gruber discovered dozens of species of fluorescent fish, including a fluorescent shark, which opened up new questions. What would a fluorescent shark look like to another fluorescent shark? Gruber enlisted researchers in optics to help him construct a special “shark’s eye” camera. (Sharks see only in blue and green; fluorescence, it turns out, shows up to them as greater contrast.) Meanwhile, he was also studying creatures known as comb jellies at the Mystic Aquarium, in Connecticut, trying to determine how, exactly, they manufacture the molecules that make them glow. This led him to wonder about the way that jellyfish experience the world. Gruber enlisted another set of collaborators to develop robots that could handle jellyfish with jellyfish-like delicacy.

President for Sale - A survey of today's political ads.
On a mid-October Sunday not long ago sun high, wind cool-I was in Harrisburg, Pennsylvania, for a book festival, and I took a stroll. There were few people on the streets-like the population of a lot of capital cities, Harrisburg's swells on weekdays with lawyers and lobbyists and legislative staffers, and dwindles on the weekends. But, on the façades of small businesses and in the doorways of private homes, I could see evidence of political activity. Across from the sparkling Susquehanna River, there was a row of Democratic lawn signs: Malcolm Kenyatta for auditor general, Bob Casey for U.S. Senate, and, most important, in white letters atop a periwinkle not unlike that of the sky, Kamala Harris for President.
