When Simone Manuel received the gold for the women’s 100-meter freestyle swim at the Rio Olympics in early August, the win represented more than just the culmination of Manuel’s many years of training and a victory for her country. It was a triumph over long-held racist stereotypes that black people are poor swimmers. Manuel was […]

A couple years ago, I was part of the team that discovered the first Earth-sized planet, Kepler-186f, rotating comfortably in its star’s “habitable zone,” where water can be liquid. Its sun, Kepler 186, is faint and far away from us—and a little colder than we’d like if we were to settle there—but it does have […]

There is a church in Argentina called Iglesia Maradona. In this church, God is football—soccer—and its prophet is the renowned player Diego Armando Maradona. Founded in 1998, the year after the star’s retirement, the Church of Iglesia Maradona now has some 120,000 members worldwide, who bear its insignia D10S—a portmanteau of Dios, the Spanish word […]

In a world where only 1 in 5 American adults meet the minimum daily exercise requirements, exercise addiction can seem like the opposite of a problem. Don’t let that fool you, says Marilyn Freimuth, a clinical psychologist at Fielding Graduate University, in Santa Barbara. “Exercise addiction can completely take over someone’s life.

Ever since ancient Greek Olympians downed exotic meats, “magic” potions, and animal hearts and testicles, athletes have tried to improve their performances by consuming special substances. Such behavior wasn’t considered cheating back in ancient times, and this attitude continued into the modern revival of the games. When a runner named Thomas Hicks famously won the 1904 […]

Last month a long thread evolved on Hacker News, a popular discussion forum, in response to my Nautilus article, “We Should Not Accept Scientific Results That Have Not Been Repeated.” Much to my delight, it generated a rich conversation involving scientists and non-scientists alike. That’s fitting, since our inability to independently replicate our results, I […]

On the second day of the Rio Olympics, American swimmer Michael Phelps won his 19th gold medal (he would go on to win four more), becoming the world’s most decorated Olympic athlete. The next day, Phelps revealed that he also has what may be the world’s best game face. While waiting for a semifinal race, […]

I bet when you woke up this morning, even before you opened your eyes, you knew where all of your limbs were. You didn’t have to look at, or try moving them, to feel their presence. This is because you have the power of proprioception (it’s also sometimes called “kinesthesis”). Because it’s a sense, just […]

When San Francisco Giants pitcher Madison Bumgarner stands on the mound, he looks as if he’s stalking the batter at the plate. The first part of his wind-up seems deliberate, almost prayer-like. From the stretch, he brings his glove, on his right hand, up slowly, so that it’s just under his chin as he eyes […]

It happened in an instant: a resounding crack and the bottom half of French gymnast Samir Ait Said’s leg was dangling like a marionette’s, his face contorted in pain. At the Rio Olympics, Said had just performed a thrilling triple backflip on the vault. When he landed, his leg snapped on impact. Said’s shot at […]
