’RECENTLY AT THE Laboratory for Laser Energetics in Brighton, New York, one of the world’s most powerful lasers blasted a droplet of water, creating a shock wave that raised the water’s pressure to millions of atmospheres and its temperature to thousands of degrees. X-rays that beamed through the droplet in the same fraction of a second offered humanity’s first glimpse of water under those extreme conditions.

The X-rays revealed that the water inside the shock wave didn’t become a superheated liquid or gas. Paradoxically—but just as physicists squinting at screens in an adjacent room had expected—the atoms froze solid, forming crystalline ice…

The findings, published this week in Nature, confirm the existence of “superionic ice,” a new phase of water with bizarre properties. Unlike the familiar ice found in your freezer or at the north pole, superionic ice is black and hot. A cube of it would weigh four times as much as a normal one. It was first theoretically predicted more than 30 years ago, and although it has never been seen until now, scientists think it might be among the most abundant forms of water in the universe.

Across the solar system, at least, more water probably exists as superionic ice—filling the interiors of Uranus and Neptune—than in any other phase, including the liquid form sloshing in oceans on Earth, Europa and Enceladus. The discovery of superionic ice potentially solves decades-old puzzles about the composition of these “ice giant” worlds.…’

How to do nothing: resisting the attention economy:

’In 2015, Jenny Odell started an organization she called The Bureau of Suspended Objects. Odell was then an artist-in-residence at a waste operating station in San Francisco. As the sole employee of her bureau, she photographed things that had been thrown out and learned about their histories. (A bird-watcher, Odell is friendly with a pair of crows that sit outside her apartment window; given her talent for scavenging, you wonder whether they’ve shared tips.)

Odell’s first book, “How to Do Nothing: Resisting the Attention Economy,” echoes the approach she took with her bureau, creating a collage (or maybe it’s a compost heap) of ideas about detaching from life online, built out of scraps collected from artists, writers, critics and philosophers. In the book’s first chapter, she remarks that she finds things that already exist “infinitely more interesting than anything I could possibly make.” Then, summoning the ideas of others, she goes on to construct a complex, smart and ambitious book that at first reads like a self-help manual, then blossoms into a wide-ranging political manifesto.…’

’“Prohibitionist strategy is unsustainable,” reads the policy plan…. The five-year policy plan calls for prescribing treatment programs instead of punishments to drug users. It’s unclear what effects the laws would have on Mexican cartels, which make the bulk of their money selling drugs in the U.S.…’
