Crystallization usually starts with an impurity, like a tiny speck of dust, something for crystals to grow from and build upon (also known as nucleation). [Then,] ice freezes from the outside in because the tray and surface of the water are exposed to colder temperatures. [And finally,] crystallization pushes away impurities (such as dissolved minerals and gases), therefore in the case of ice cubes, these impurities are pushed to the center of the ice cubes.

Artificial intelligence isn’t creating fake photos and videos — it can do fake voices, too. Up until now, these voices have been noticeably stilted and robotic, but researchers from AI startup Dessa have created what is by far the most convincing voice clone we’ve ever heard — perfectly mimicking the sound of MMA-commentator-turned-podcaster Joe Rogan. Listen to clips of Dessa’s AI Rogan below, or take a quiz on the company’s site to see if you can spot the difference between real Rogan and faux Rogan. (It’s surprisingly hard!)

My friend April, adventurous sailor and world traveler, had told me of Moonhole not long after we sailed our boats to the Caribbean island of Bequia. The story was one that captured my attention and drew me in instantly. It was a story of an American — Tom Johnston — who dreamed of living a life at one with nature, a life of peacefulness without the trappings of society, without electricity or technology. A story of how that same American, in 1964, founded a community of homes that were built with materials only found on the small island of Bequia — whale bones, rocks, shells, concrete, discarded anchor chains, etc.

In the shadow of World War II, modern capitalism was beginning to take shape. Manufacturing was booming. Consumerism was on the rise. Modern ideas about worker productivity were starting to take shape. In 1953, a British designer named Robert Francis Wilson published a book describing how color could make work–and workers–happier. Bright, colorful workspaces make employees healthier, Wilson explained. Drab, gray, messy offices and factories “promote the feeling of depression.” His ideas about color, and how it could transform work, held up a mirror to emerging ideas about labor and the workplace. In theory, color is simple–as empirical as mathematics or chemistry. There’s only so much of the spectrum that’s visible to our human eyeballs, as Newton realized 300 years ago. But the simplicity begins and ends there. The way people perceive color is nearly as social and as dynamic as language itself. As historian and author Alexandra Loske puts it in her new book, “The order of color, both practically and conceptually, is a mirror of its time as well as the person who created it.” In other words, color has a secret social history that tends to go unnoticed–the premise of Loske’s Color: A Visual History From Newton to Modern Color Matching Guides, a weighty new tome that collects hundreds of years of guides to color and the wildly diverse authors behind them, from chemists to architects to Jesuit priests-slash-entomologists. In the book, Loske looks at dozens of these color wheels, systems, and guides, beginning with Newton’s groundbreaking 1704 treatise Opticks, which identified the colors that human eyes could see. Maybe it’s no surprise that the Enlightenment, an era obsessed with rationality and empiricism, was also fixated on color. As Loske explains, scientists, artists, writers, and naturalists of all sorts published their own treatises on color, inspired by Newton, giving rise to what she calls “the eighteenth century color revolution.”

Thirty-nine years ago today, on August 30, 1974, at least one and probably two grisly murders occurred in one of the most faraway locales on planet Earth–a small Pacific atoll called Palmyra, a thousand miles south of Hawaii, which has no permanent human population. The one victim that we know of was Eleanor Graham, called Muff, but her husband, Malcolm “Mac” Graham III, age 43, vanished. The married couple were yachting around the Pacific on their impressive sailboat called the Sea Wind, and they had unfortunately chosen the wrong island to camp on. The killer was Buck Duane Walker, also known as Wesley G. Walker, a tough ex-convict and noted con artist, who had also sailed to Palmyra that summer with his girlfriend, Stephanie Stearns. The Grahams were upper-crust people, pretty conservative and reserved. Walker and Stearns were thought of by the Grahams as “hippies,” free-spirited, but Walker certainly had a dark side. Their boats were anchored in a lagoon near each other, and the couples inevitably came into conflict. Stearns was pretty easy to get along with so most of the conflict came from Walker. On August 30, according to Stephanie Stearns, Buck Walker told her that the Grahams had invited the two of them over for dinner aboard the Sea Wind. They showed up at 6:30 PM but the Grahams weren’t there. Walker told his girlfriend that they had told them they were to “make themselves at home” if they (the Grahams) weren’t back yet from fishing. Dark came, no sign of them. In the morning they began searching and found an overturned boat on the shore of the lagoon. Walker and Stearns concluded that the Grahams had a fishing accident.

Christian LeBlanc’s plan was to graduate business school and work full-time at one of Canada’s largest accounting firms. But in his last year of university, the Vancouver resident did an exchange program in Bangkok, Thailand and started making videos of his travels for his family and friends and posting them on YouTube for fun. He came back to Canada to work long hours and lots of weekends at a job he didn’t like. So, at age 22, he decided to quit accounting, sell everything he owned and scrape together “just enough money for a one-way ticket” back to Bangkok. He lived like a “broke backpacker” for a year before his YouTube business took off.
