On Saturday afternoon, while I really should have been working on other things, this happened: What’s going on here? It might be obvious if you have a background in biology, but there’s a lot of context, and science, behind that tweet. It all started last Friday, when astrophysicist and popular science personality Neil deGrasse Tyson […]

Can an organism ever become perfectly evolved? In Richard Lenski’s lab at Michigan State University, scientists are trying to see if that’s possible. The idea grew out of the lab’s Long-Term Evolution Experiment, started in 1988, with Escherichia coli; in 2010, they celebrated 50,000 generations (500 occur every 75 days). The lab has 12 populations […]

Before Josh McDermott was a neuroscientist, he was a club DJ in Boston and Minneapolis. He saw first-hand how music could unite people in sound, rhythm, and emotion. “One of the reasons it was so fun to DJ is that, by playing different pieces of music, you can transform the vibe in a roomful of […]

The animals of neuroscience research are an eclectic bunch, and for good reason. Different model organisms—like zebra fish larvae, C. elegans worms, fruit flies, and mice—give researchers the opportunity to answer specific questions. The first two, for example, have transparent bodies, which let scientists easily peer into their brains; the last two have eminently tweakable […]

On a recent Sunday, at my local Italian market, I considered the octopus. To eat the tentacle would be, in a way, like eating a brain—the eight arms of an octopus contain two-thirds of its half billion neurons. Delicious for some, yes—but for others, a jumping off point for the philosophical question of other minds. […]

The path to Ohe’o Gulch, in Maui, meanders through a short section of forest, past mango trees and pockets of bamboo, then opens onto the ocean. Palm trees of all sizes and varieties line the Pacific coast, their trunks hunched over the sand, fronds waving picturesquely in the trade winds. Though they may seem perfectly […]

The staunch atheist and essayist Christopher Hitchens once said that “the most overrated of the virtues is faith.” It’s a reasonable conclusion if you believe, as the astrophysicist Carl Sagan did, that “extraordinary claims require extraordinary evidence.”1 To believe something without evidence—or have faith—is, in their view, something to avoid (and, when called for, to […]

In May 2015, an official vote was held by the Oxford University Student Union about clothing policy. It was over whether to keep “subfusc,” a traditional uniform dating back to the mid-seventeenth century—comprised of a dark suit or skirt, black shoes, white shirt, and a white or black bow tie or ribbon—mandatory for exams. The […]

Queen ants fight dirty. With their powerful jaws, they clamp down on ­each other, ripping through exoskeleton and vital flesh—a fight to the death. The spoils of victory include the deceased’s entire colony.  The queen with the broader head and stronger jaws is most likely to win. When we think of animal weapons—antlers, tusks, horns, […]
