The original version of this story appeared in Quanta Magazine.Hard problems are usually not a welcome sight. But cryptographers love them. That’s because certain hard math problems underpin the security of modern encryption. Any clever trick for solving them will doom most forms of cryptography.Several years ago, researchers found a radically new approach to encryption that lacks this potential weak spot. The approach exploits the peculiar features of quantum physics. But unlike earlier quantum encryption schemes, which only work for a few special tasks, the new approach can accomplish a much wider range of tasks. And it could work even…

“Wake Up Dead Man: A Knives Out Mystery” is an enticingly clever and droll, nearly pitch-perfect piece of murder-mystery fun — a gothic whodunit that lives up to the expectations set six years ago by “Knives Out,” which offered its own perfect revival of the Agatha Christie spirit, with a tasty frosting of meta cheekiness. (It invited you to watch yourself watching yourself try to solve a deviously orchestrated crime.)

The Chinese have discovered a massive deposit of lithium in Liberia. Yet to many of us that news is bittersweet. Why? Because we’ve seen this story before. Foreign companies swoop in, dig up our land, carry off our wealth, destroy our ecosystems, then leave us with nothing but holes in the ground. A few politicians line their pockets while ordinary Liberians remain dirt poor. That’s business as usual. But lithium is no ordinary mineral. It powers the future — electric cars, cell phones, robots. The world is hungry for it, and Liberia is sitting on billions of dollars’ worth. The…

This year’s Sundance saw the real-life couple Dave Franco and Alison Brie play with the grotesque reality of being literally stuck to one another in the body horror Together, a wincingly effective lark that turned codependency into a curse. It didn’t really find its audience upon too-wide release this summer, a campaign that couldn’t succinctly explain the plot or convey a tone that went from horror to comedy and back again.At Toronto, YouTuber turned film-maker Curry Barker’s similarly themed Obsession should be an easier sell when it gets swiftly bought and packaged (it’s entering the festival as a sure-to-be-fought-over sales…
