From specialized motors to the use of machine-learning algorithms, Turkey's billion-dollar hair-transplant industry is the result of a constant process of innovation. The astounding growth of the hair-transplant industry in Turkey is not just a medical tourism success story; it's also a tale of "hacked" medical equipment and algorithmic craftsmanship. From a biological and evolutionary perspective, human hair is often viewed as an unremarkable mass of keratin that still plays some important functions--protecting our scalps from the sun's harmful ultraviolet rays and regulating our body temperatures--but, for the most part, is no longer essential to our survival. Yet, since ancient times, our subconscious perceptions of whether another person is healthy, young, or fertile have been based on visual cues such as skin radiance, the integrity of teeth, and hair density. Deep within our perceptions, hair has become one of the most powerful representations of our identity and self-confidence. Today, the global hair-transplant and restoration industry, which has evolved around this deep psychological and evolutionary need, has grown into a massive, multibillion-dollar industry. Various research firms have estimated the total size of the global hair-transplant market as sitting somewhere between $7.33 billion and $11.61 billion in 2024. And those figures don't include the underground economy.

Keychron's K2 HE Concrete Edition sounds like a cute gimmick, but as I discovered, there's a really solid keyboard beyond the absurd choice of materials. Concrete case has significant tradeoffs in weight and practicality. In-browser customization requires physical connection. Yes, Keychron made a . The cause of scraped knees, bike-tire skid marks, and finger-painted signatures is now the foundation of a keyboard.

Dads are traditionally tough to shop for--let me help with these handpicked gift ideas for fathers with great taste. The only Father's Day gift I can recall my own dad getting was a plate of fried sardines. It was prepared by my mother, his ex-wife, who knew how gratefully he'd receive a dish he grew up with in the Italian neighborhood of a steel town dying with such theatrical flair that Bruce Springsteen named a song after it. We lived in a nearby city that had plenty of red-sauce restaurants, but they weren't serving tinned fish in those days. As my father had only the most limited of food preparation skills and didn't date the kind of women who could cook, this was the only way he'd ever taste that flavor again. As Father's Day gifts go, being united with a long-lost recipe from childhood is pretty good.

Soon-to-be-laid-off Meta contractors say they're being treated differently than Mark Zuckerberg's full-time employees, who stand to receive more generous severance packages. Now we're being left behind," chanted a horde of contract workers who gathered outside Meta's offices in Dublin, Ireland, on Friday afternoon. Waving flags, brandishing signs, and armed with whistles and vuvuzelas, they were out to protest a round of planned layoffs. The workers are employed by Dublin-based company Covalen, which handles content moderation and data labeling services that help Meta to fine-tune its AI products. In April, Covalen told 700 employees that their jobs were at risk, citing "reduced demand," WIRED reported . A large swath of the affected workers won't receive any severance because they've been employed for less than two years. The rest are being offered the minimum payout required under local labor laws--two weeks' pay for every year of employment--according to the Communications Workers' Union (CWU), whose members include Covalen employees. "We're just getting the crumbs here," Aadel Obaid, a team manager at Covalen who is part of the planned layoffs, tells WIRED. "Give us a little bit of the pie." To try to compel Covalen into revising the severance package, workers voted to strike outside the company's corporate office, before marching to Meta's nearby European headquarters. According to John Bohan, an organizer at the CWU, Meta could use its leverage as an anchor client to pressure Covalen into offering its employees an enhanced severance package. The workers are asking for double what's currently being offered--and at least some form of payment for workers who don't meet the two-year threshold. The company could also release Covalen workers from a "cooldown period" preventing them from working on another Meta account for six months after being laid off, Bohan says. At 1 pm local time on Friday, the striking workers began to gather outside Covalen's corporate headquarters, a red-brick office building on an otherwise largely residential street in the heart of Dublin. The protests began with a wall of sound: the workers beat drums, booed, whistled, shouted, and catcalled. Then came a volley of call-and-response chants led by a worker with a megaphone. The building's security guard watched, bemused, from inside the lobby, hands on his hips. Two hours later, the group--now more than 150 people--began to march down the center of the mile-long stretch of road to Meta's campus, slowing the trailing traffic to a crawl. Dubliners enjoying the early onset of summer stopped to gawp; some applauded. When the protesters arrived at Meta's complex, two security guards stood with crossed arms, blocking the way. The group set up at the gates and began another round of chants: "We scrub the feed.

When Pope Leo XIV presented his first encyclical on artificial intelligence at the Vatican on Monday, he invited Christopher Olah, cofounder of Anthropic, to speak. The move signaled an unprecedented alliance between the Catholic church and Silicon Valley. But to understand how this partnership came about, we need to go back to Anthropic's founding. Anthropic launched in 2021 after a group of OpenAI researchers, including Dario and Daniela Amodei, left to form a rival lab. They did so with a clear conviction: Artificial intelligence models were becoming too powerful to be developed exclusively according to the logic of competition and speed.

The individual pieces create a kind of illusion. When a horse trots, is there a moment when its four feet are in the air simultaneously? In the 1870s, Leland Stanford, the railroad magnate and benefactor of the university that bears his name, funded an effort to find out. The answer shocked many equestrian experts and artists: The horse's feet leave the ground together, but not when outstretched as commonly depicted in paintings and carousels; the feet do so when they reach inward, toward the horse's belly. Surprisingly, this discovery about a horse's gait sheds light on a much more modern debate--whether A.I. is on a path to consciousness.

These Robots Are Making Meals for a Nonprofit in San Francisco's Tenderloin A nonprofit in the city's most troubled district has turned to robotic meal prep tech to make up for a dearth of human volunteers. Project Open Hand, a nonprofit founded in 1985 by local grandmother and HIV-awareness advocate Ruth Brinker, prepares and packages meals to meet the diverse nutritional requirements of people who need them. The effort began in response to the AIDS crisis, but the nonprofit has since expanded the meals it makes for people with conditions such as heart disease, diabetes, or chronic kidney disease. But it takes many people to make these meals, and Project Open Hand has struggled to entice volunteers to help fill the meal kits. The organization is housed in a four-story building in San Francisco's Tenderloin district.

Don't miss these vacuum deals happening over the holiday weekend. Shopping for a Dyson vacuum is an experience. There are many models to navigate and serious price tags on most of them. As someone who tests vacuums for a living, I have to admit that a Dyson blows most other vacuums away. There are a few cheaper models I'll still grab (check out my full guide to cordless and robot vacuums for more recommendations), but if you're dreaming of a Dyson, this weekend is a great time to buy.
