Immunology Is Where Intuition Goes to Die

There’s a joke about immunology, which Jessica Metcalf of Princeton recently told me. An immunologist and a cardiologist are kidnapped. The kidnappers threaten to shoot one of them, but promise to spare whoever has made the greater contribution to humanity. The cardiologist says, “Well, I’ve identified drugs that have saved the lives of millions of people.” Impressed, the kidnappers turn to the immunologist. “What have you done?” they ask. The immunologist says, “The thing is, the immune system is very complicated …” And the cardiologist says, “Just shoot me now.”

Hygiene Theater Is a Huge Waste of Time

As a covid-19 summer surge sweeps the country, deep cleans are all the rage.

National restaurants such as Applebee’s are deputizing sanitation czars to oversee the constant scrubbing of window ledges, menus, and high chairs. The gym chain Planet Fitness is boasting in ads that “there’s no surface we won’t sanitize, no machine we won’t scrub.” New York City is shutting down its subway system every night, for the first time in its 116-year history, to blast the seats, walls, and poles with a variety of antiseptic weaponry, including electrostatic disinfectant sprays. And in Wauchula, Florida, the local government gave one resident permission to spray the town with hydrogen peroxide as he saw fit. “I think every city in the damn United States needs to be doing it,” he said.

How Poverty Changes the Brain

You saw the pictures in science class—a profile view of the human brain, sectioned by function. The piece at the very front, right behind where a forehead would be if the brain were actually in someone’s head, is the pre-frontal cortex. It handles problem-solving, goal-setting, and task execution. And it works with the limbic system, which is connected and sits closer to the center of the brain. The limbic system processes emotions and triggers emotional responses, in part because of its storage of long-term memory.

Wait, So How Much of the Ocean Is Actually Fished?

How much of the world’s oceans are affected by fishing? In February 2018, a team of scientists led by David Kroodsma from the Global Fishing Watch published a paper that put the figure at 55 percent—an area four times larger than that covered by land-based agriculture. The paper was widely covered, with several outlets leading with the eye-popping stat that “half the world’s oceans [are] now fished industrially.”
