Though you couldn't tell from the picture, these particular headphones incorporated a miniature fakir's bed of soft plastic spikes above each ear, pressing gently into the skull and delivering pulses of electric current to the brain. Made by a Silicon Valley startup called Halo Neuroscience, the headphones promise to "accelerate gains in strength, explosiveness, and dexterity" through a proprietary technique called neuropriming. "Thanks to @HaloNeuro for letting me and my teammates try these out!" McAdoo tweeted. On Thursday night, McAdoo and his teammates will seek the eighty-ninth and final win of their record-breaking season, as they defend their National Basketball Association title in Game 6 of the final series against LeBron James's Cleveland Cavaliers. The headphones' apparent results, in other words, have been impressive.
The following was delivered as the commencement address at the California Institute of Technology, on Friday, June 10th. If this place has done its job--and I suspect it has--you're all scientists now. Sorry, English and history graduates, even you are, too. Science is not a major or a career. It is a commitment to a systematic way of thinking, an allegiance to a way of building knowledge and explaining the universe through testing and factual observation.
On June 6, 2015, Kalief Browder took his own life at his home, in the Bronx. He was twenty-two years old. He had been released from Rikers Island two years earlier, ending an ordeal that had begun on a spring night in 2010, when he had been arrested for robbery, at sixteen. He spent the next three years in jail trying to prove his innocence, and, for about two of those years, he was held in solitary confinement, where he attempted suicide several times. The charges against him were eventually dropped.
On a bitter, soul-shivering, damp, biting gray February day in Cleveland--that is to say, on a February day in Cleveland--a handless man is handling a nonexistent ball. Igor Spetic lost his right hand when his forearm was pulped in an industrial accident six years ago and had to be amputated. In an operation four years ago, a team of surgeons implanted a set of small translucent "interfaces" into the neural circuits of his upper arm. This afternoon, in a basement lab at a Veterans Administration hospital, the wires are hooked up directly to a prosthetic hand--plastic, flesh-colored, five-fingered, and articulated--that is affixed to what remains of his arm. The hand has more than a dozen pressure sensors within it, and their signals can be transformed by a computer into electric waves like those natural to the nervous system.
In the winter of 2012, I travelled from New Delhi, where I grew up, to Calcutta to visit my cousin Moni. My father accompanied me as a guide and companion, but he was a sullen and brooding presence, lost in a private anguish. He is the youngest of five brothers, and Moni is his firstborn nephew--the eldest brother's son. Since 2004, Moni, now fifty-two, has been confined to an institution for the mentally ill (a "lunatic home," as my father calls it), with a diagnosis of schizophrenia. He is kept awash in antipsychotics and sedatives, and an attendant watches, bathes, and feeds him through the day.
"Smarter Faster Better: The Secrets of Being Productive in Life and Business" (Random House) is Charles Duhigg's follow-up to his best-selling "The Power of Habit: Why We Do What We Do in Life and Business," which was published in 2012. The new book, like its predecessor, has a format that's familiar in contemporary nonfiction: exemplary tales interpolated with a little social and cognitive science. The purpose of the tales is to create entertaining human-interest narratives; the purpose of the science is to help the author pick out a replicable feature of those narratives for readers to emulate. What enabled the pilot to land the badly damaged plane? How did the academic dropout with anxiety disorder become a champion poker player?
