Comment Re:'Cuz they'll stop making non-AI versions (Score 1) 108

If the toaster has good brownness and heat-bounce sensors, I'm not sure AI is needed: just turn up or down the heat cells where needed to keep it even. Statistical analysis may be needed to manage adjacent cells, but once the formulas are known via lab testing it should be predictable.

Comment Firefox has some kind of leak (Score 1) 108

on my PC. I can't see it in Task Manager, but start getting "out of memory" errors after a couple of weeks and have to reboot. Restarting Firefox alone is insufficient to clear it. I suspect it has something to do with the graphics card rather than primary RAM, and could be co-caused with some other app.

Submission + - Scientists Create a New Form of Ice at 2,357 Degrees Celsius (sciencealert.com)

fahrbot-bot writes: Science Alert is reporting that Scientists have now demonstrated one of the weirdest forms of ice yet – under preposterous pressures up to 2.3 million atmospheres, and tremendous temperatures up to 2,630 kelvins (2,357 degrees Celsius, or 4,274 degrees Fahrenheit).

This superionic water ice is a deeply odd state of matter that's neither entirely solid nor entirely liquid. Its oxygen atoms remain fixed in a rigid crystal lattice, as they would in a solid. But the hydrogen nuclei are mobile, diffusing through that lattice more like particles in a liquid.

Researchers squeezed the samples between the tips of diamonds to pressures as high as 230 gigapascals, while using lasers to heat them to thousands of degrees. That's 2.3 million times Earth's atmospheric pressure at sea level – the pressure at the center of Earth, for context, is around 360 gigapascals.

Then, using an extremely narrow beam of synchrotron X-rays, they probed for changes in the crystal structure of the ice.

What emerged was a configuration predicted theoretically but never unambiguously observed in experiments: hexagonal close-packed, or hcp, ice. As the hcp crystal was heated, its expansion also showed a signature of superionic behavior, suggesting it entered the superionic state at around 1,700 kelvins.

Superionic ice is thought to exist deep inside Uranus and Neptune, where its unusual properties may play a role in generating the planets' equally unusual magnetic fields.

The findings have been published in Physical Review Letters: Observation of Hexagonal Close-Packed Water Ice at Conditions in Ice Giant Planetary Interiors
