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.

GET IT TOGETHER
In the beginning was the mob, and the mob was bad. In Gibbon’s 1776 “Decline and Fall of the Roman Empire,” the Roman mob makes regular appearances, usually at the instigation of a demagogue, loudly demanding to be placated with free food and entertainment (“bread and circuses”), and, though they don’t get to rule, they sometimes get to choose who will.
