Let’s say your relationship is on the rocks. You’ve been trying to work things out together in couples’ counselling, but ultimately, you want to know if it is worth the effort. Will things get better, or are they doomed to fall apart?

These are dark days for supplements. Although they are a $30-plus billion market in the United States alone, vitamin A, vitamin C, vitamin E, selenium, beta-carotene, glucosamine, chondroitin, and fish oil have now flopped in study after study. If there was one supplement that seemed sure to survive the rigorous tests, it was vitamin D. People with low levels of vitamin D in their blood have significantly higher rates of virtually every disease and disorder you can think of: cancer, diabetes, obesity, osteoporosis, heart attack, stroke, depression, cognitive impairment, autoimmune conditions, and more.

The box office king and Trump golf antagonist beat a crack addiction to build a film career unrivaled in modern stardom, and the 70-year-old 'Glass' actor aims to work well into his 80s — if Marvel and the rest of Hollywood can afford him: "I'm a gunslinger now."

The long read: Five years after his last taste of alcohol, William Leith tries to understand its powerful magic

Truly revolutionary political transformations are naturally of great interest to historians, and the French Revolution at the end of the 18th century is widely regarded as one of the most influential, serving as a model for building other European democracies. A paper published last summer in the Proceedings of the National Academy of Sciences, offers new insight into how the members of the first National Constituent Assembly hammered out the details of this new type of governance.

This month, we are all tentatively dipping our toes into the New Year, wondering what horrors and highlights might await us in 2019 — the year that served as a setting, you may remember, for Blade Runner, Akira, and Running Man, three of the most iconic future-casting movies ever made and now divergent choose-your-own-dystopia visions of the years ahead (perhaps some more plausible than others).

When she was in cosmetology school, Tracy Lozano had a love-hate relationship with weekday mornings. Those predawn moments were the only time she saw her infant daughter awake, and she savored them. When the time came to hand the baby to her own mother, she said in a recent interview, she would stifle her tears, letting them roll only when she had closed the door behind her.

Is there any hope on climate change, or are we just screwed? I hear this question all the time. When people find out what I do for a living, it is generally the first thing they ask. I never have a straightforward or satisfying answer, so I usually dodge it, but in recent years it has come up more and more often. So let’s tackle it head on. In this post, I will lay out the case for pessimism and the case for (cautious) optimism, pivoting off a new series of papers from leading climate economists.

There's nothing like the prospect of being hanged in the morning to focus the mind." Eben Upton is describing the weight of public expectation that fell on his shoulders after the prototype of the $35 Raspberry Pi computer he co-created was revealed online in May 2011. After five years of tinkering with the board's design in relative anonymity, suddenly the number of people aware of the project exploded, with the YouTube video of the early Pi racking up 600,000 views in just two days.

“I do not believe that I have ever written a children’s book,” the great Maurice Sendak once said in an interview. “I don’t write for children,” he told Colbert. “I write — and somebody says, ‘That’s for children!’” This sentiment — the idea that designating certain types of literature as “children’s” is a choice entirely arbitrary and entirely made by adults — has since been eloquently echoed by Neil Gaiman, but isn’t, in fact, a new idea.

It was just before closing time at a Verizon store in Bushwick, New York last May when I burst through the door, sweaty and exasperated. I had just sprinted—okay I walked, but briskly—from another Verizon outlet a few blocks away in the hopes I’d make it before they closed shop for the night. I was looking for a SIM card that would fit a refurbished 2012 Samsung Galaxy S3 that I had recently purchased on eBay, but the previous three Verizon stores I visited didn’t have any chips that would fit such an old model.

Julia Rohrer wants to create a radical new culture for social scientists. A personality psychologist at the Max Planck Institute for Human Development, Rohrer is trying to get her peers to publicly, willingly admit it when they are wrong. To do this, she, along with some colleagues, started up something called the Loss of Confidence Project. It’s designed to be an academic safe space for researchers to declare for all to see that they no longer believe in the accuracy of one of their previous findings. The effort recently yielded a paper that includes six admissions of no confidence. And it’s accepting submissions until January 31.

“Are we ready to open the doors?” an event producer in a skintight catsuit asked into a headset. As EDM blasted over a PA system, hundreds flooded into the ballroom of San Diego’s Town & Country resort: tanned-and-toned millennials, a group of friends from Venezuela, an engineer from Lagos, Botoxed retirees, and elderly couples pushing Zimmer frames. They took their seats, awaiting the good news:

The future book was meant to be interactive, moving, alive. Its pages were supposed to be lush with whirling doodads, responsive, hands-on. The old paperback Zork choose-your-own-adventures were just the start. The Future Book would change depending on where you were, how you were feeling. It would incorporate your very environment into its story—the name of the coffee shop you were sitting at, your best friend’s birthday. It would be sly, maybe a little creepy.

On a late-summer day in Los Angeles, I plan to meet Terry Crews at the Getty Museum because, in addition to everything else Crews does—which, seriously, is everything—he’s a hugely talented visual artist. I figure we’ll go deep on the photography exhibit. I’ll ask: “Terry, what’s the inner monologue of the person in this picture?” Really get my Barbara Walters on. What happens instead is that we get nine steps into the Getty Center, turn to one another, and talk for five solid hours—about toxic masculinity...

When Johansson gets punched in the face, Heidi Moneymaker takes the hit. When Elizabeth Olsen crashes through a window, it's C.C. Ice who ends up with scratches. Hollywood's most unsung behind-the-scenes heroes star in a Hollywood Reporter photo portfolio.

Self restraint is necessary to reach goals. But the modern world constantly tests our willpower and hinders our productivity–whether with social media, chatty colleagues, or old-fashioned daydreaming. And people with better self restraint are more successful than those with less. So how can you increase your self restraint and build the willpower to more successfully complete your goals?

Investors all over the world fell for the schemes of the man who called himself Khalid bin al-Saud. But the truth turned out to be more incredible than the lie.

The 33 special agents assigned to the Investigative Services Branch handle the most complex crimes committed on NPS land. When a day hike in Rocky Mountain National Park ended in a grisly death, ISB veteran Beth Shott hit the trail, where she began unraveling a harrowing case.

On August 5, 2013, Dutch scientist Mark Post presented to the world the first lab-grown burger ever created. The event took place in London, the burger was cooked by chef Richard McGeown, and only Hanni Ruetzler and Josh Schonwald – two food critics – could taste it. Hanni Ruetzler said that it tasted like meat, “just not as juicy.”

On the new triangle trade, and the surprising connection between modern slavery and ecological disaster.

Soya, almond, oat... Whether for health issues, animal welfare or the future of the planet, ‘alt-milks’ have never been more popular. Are we approaching dairy’s final days? A couple of weeks ago, some eye-catching billboards began appearing around central and east London. Entire tunnels of the underground were plastered with the adverts; the sides of large buildings were covered.

Nearly every measurement of weight you’ve ever made, from peeking at your bathroom scale to measuring out flour for a recipe, can be traced back to just a single object: a metal kilogram made of platinum and iridium that resides under lock and key in an underground vault in Paris. It’s called the International Prototype Kilogram, or IPK, and since its creation in 1889 it has been the standard by which the world’s weights are defined. But not for much longer.

Gas station hotdogs don't take breaks. You may pull into a rest stop, refill your car’s tank, empty your own, grab some snacks, and peel out again. The whole time, the dogs will have been rotating, slowly, on their shiny metal rollers. When you finally turn in for the night, they may be turning still.

When it comes to events in space, 2019 is going to be an extraordinary year. That’s not to say 2018 will be an easy act to follow. After all, SpaceX debuted the world’s most powerful operational launch system (called Falcon Heavy), sent a car beyond Mars, and helped lift off more orbital rockets than in any year since 1990.

Juan Sanchez grew up along the Mexican border in a two-bedroom house so crowded with children that he didn’t have a bed. But he fought his way to another life. He earned three degrees, including a doctorate in education from Harvard, before starting a nonprofit in his Texas hometown. Mr. Sanchez has built an empire on the back of a crisis.

In 1985, a premature baby was born in Maryland who needed surgery to tie off a dangerous blood vessel near his heart. The newborn, Jeffrey, died weeks after the procedure. His family learned afterwards that none of the procedures had been performed with analgesics; the only drug administered was a muscle relaxant. The press ran with the story, alerting Americans to the grim realization that hospitals in the United States routinely operated on critically ill premature babies without giving them painkillers.

Soon after I set out to write a book about psychedelics, it became obvious what I would have to do: Trip, and then write about what it was like. True, I could have relied on the testimony of others, but that seemed less than satisfying. Ever since the 11-year-old me read George Plimpton’s account of playing football in “Paper Lion” (1966), I’ve believed that the most absorbing way to convey an experience is to have it yourself and then try to describe it from the inside. Best of all is to have it yourself for the first time, which is the only time the comprehensive wonder of any experience is available to us.

The Incas left no doubt that theirs was a sophisticated, technologically savvy civilisation. At its height in the 15th century, it was the largest empire in the Americas, extending almost 5000 kilometres from modern-day Ecuador to Chile. These were the people who built Machu Picchu, a royal estate perched in the clouds, and an extensive network of paved roads complete with suspension bridges crafted from woven grass. But the paradox of the Incas is that despite all this sophistication they never learned to write.

“The world isn’t short of water, it’s just in the wrong place, and too salty," says Charlie Paton – so he's spent the past 24 years building the technology to prove it
