Vast underground water system helps drive Antarctica’s glaciers

Lake Whillans is a strange body of water, starting with the fact that there is liquid to fill it at all. Though buried under more than 2,000 feet of Antarctic ice, its temperatures climb to just shy of 0° Celsius, thanks to a combination of geothermal warmth, intense friction from ice scraping rock, and that thick glacial blanket protecting it from the polar air. Given the immense pressure down there, that’s just balmy enough to keep the lake’s water watery. Stranger still, Lake Whillans is also teeming with life. One survey a decade ago found thousands of varieties of microscopic critters, thought to be feeding on nutrients left by seawater that sloshed into the basin several millennia ago, when the glaciers last pulled back.

More recently, Chloe Gustafson, a geophysicist at Scripps Institution of Oceanography, arrived on the remote stretch of ice above Lake Whillans with a different mystery in mind: What’s happening underneath that lake? Antarctic researchers had long suspected the plumbing below the glacier went much deeper than they could see. Any groundwater beneath the lake would have implications for how the ice up above moves oceanward, and thus for how quickly it might contribute to rising seas. But they couldn’t definitively prove what groundwater was there. It was too deep, too ice-covered to map with the traditional tools of glaciology, like bouncing radar signals off the ice or setting off explosives and listening to the shockwaves.

Review: Moon Knight takes its troubled protagonist on classic voyage of the hero

Can anything good ever come of gods interfering in the affairs of men? That’s the underlying conundrum posed in Moon Knight, the latest spinoff series in the MCU’s Phase Four, and in the case of the series, the answer is a resounding yes. Starring Oscar Isaac as a tormented man with dissociative identity disorder (DID), the series has more in common with the Netflix Defenders series than with recent Marvel fare like WandaVision, The Falcon and the Winter Soldier, and Loki. But instead of taking place in New York City’s Hell’s Kitchen, it’s telling a unique superhero origin story rich in symbolism drawn from Egyptian mythology.

(Some spoilers below for the comics and the TV series. Any major reveals are at the very end, and we’ll give you a heads-up when we get there.)

As I’ve written previously, in the comics, Marc Spector (aka Moon Knight) is the son of a rabbi, marked at a young age by the Egyptian moon-god Khonshu to be the god’s avatar on Earth. But Khonshu is a supernatural entity with many aspects to his nature—and also exists out of phase with normal time and space—so forging a psychic connection with the human Marc harms the man’s mental health.

CDC reports 109 cases of puzzling hepatitis cases in kids, 5 deaths

The Centers for Disease Control and Prevention is now investigating 109 cases of unexplained liver inflammation—hepatitis—in young children from 25 states over the past seven months. Of the 109 affected children, five have died, and 15 (14 percent) required liver transplants. The children were all under the age of 10, and 90 percent were hospitalized.

The CDC’s announcement Friday marks a dramatic uptick in the US’s reported cases, which was limited to nine confirmed cases in Alabama just three weeks ago. The cases also add to a mounting global tally, which reached upward of 300 cases from more than two dozen countries.

But, despite the boom in cases, CDC and international health investigators are still puzzled about the cause of the illnesses. Severe hepatitis is rare in young children, and unexplained cases of severe hepatitis are rarer.

How Apple, Google, and Microsoft will kill passwords and phishing in one stroke

How Apple, Google, and Microsoft will kill passwords and phishing in one stroke

For more than a decade, we’ve been promised that a world without passwords is just around the corner, and yet year after year, this security nirvana proves out of reach. Now, for the first time, a workable form of passwordless authentication is about to become available to the masses in the form of a standard adopted by Apple, Google, and Microsoft that allows for cross-platform and cross-service passkeys.

Password-killing schemes pushed in the past suffered from a host of problems. A key shortcoming was the lack of a viable recovery mechanism when someone lost control of phone numbers or physical tokens and phones tied to an account. Another limitation was that most solutions ultimately failed to be, in fact, truly passwordless. Instead, they gave users options to log in with a face scan or fingerprint, but these systems ultimately fell back on a password, and that meant that phishing, password reuse, and forgotten passcodes—all the reasons we hated passwords to begin with—didn’t go away.

A new approach

What’s different this time is that Apple, Google, and Microsoft all seem to be on board with the same well-defined solution. Not only that, but the solution is easier than ever for users, and it’s less costly for big services like Github and Facebook to roll out. It has also been painstakingly devised and peer-reviewed by experts in authentication and security.
