Submission + - The brain is actually two completely separate organs (stanford.edu)

Beeftopia writes: From Stanford Medicine:

"For centuries, scientists have thought of the brain as a single, unified organ. But new research led by Stanford Medicine reveals that what we call the brain is two distinct organs that evolved independently over hundreds of millions of years."

The adult brain has three main regions: the forebrain, midbrain and hindbrain. Scientists could never create hindbrain neurons.

"Previous attempts to make hindbrain neurons likely tried to coax forebrain and midbrain progenitors into hindbrain cells, which our study shows is not possible,” said researcher Rayyan Jokhai.

"The researchers’ breakthrough came from studying the earliest moments of embryonic development, during a stage called gastrulation when the body first takes shape. Jokhai and Dundes discovered that the hindbrain follows a separate developmental path, running in parallel to — rather than branching off from — the pathway that creates the forebrain and midbrain."

With this knowledge, researchers were able to create hindbrain neurons.

we've not even seen a hint of AGI. I am sure the LLM's will get better and faster, but will they ever be intuitive ? They are already great at taking huge amounts of data and making direct connections. When they can include the mystery factor that is free-will matched with stupidity, we might have something to worry about. I am an old man now so I worry less for me than for my 14 year old nephew. Luckily he reads, and plays pen and paper RPG's.

that is actually the truth. We remove the "dangerous" elements to protect the rest. The problem lies when the worst distill into absolute anarchy. Do you believe in capital punishment ? That is truly the only way to remove the worst elements from society. While in theory I support it. I would not want to be the one deciding who gets the "final solution". Things like that seldom work out :(.

Only if we allow private equity to run for profit prisons. We tried it in Arizona. It went badly. The federal government now runs our prisons because our state legislators will not pay for or hire Dr's in prisons. We allowed a company to run them. They did, right into the ground and criminal proceedings.

Google went nuts on me yesterday when I tried to log into Civitai using my Google account. It had no problem with me logging into YouTube, or Gmail, or Reddit, but it kept throwing demands for 2FA codes (which then did not work) when I tried to use the same account for Civitai, all because my machine had rebooted after the latest Patch Tuesday. At this point I'm not even sure which thing I did that made it get unstuck.

This is why I say AI is alien intelligence. Not like "outer space" alien, but something fundamentally different in the way it was constructed. It doesn't have billions of years of evolutionary baggage. It has never been hungry. It has never dealt with the gaze of a larger, hungrier creature. We designed them to interact with us in the ways that they do. However, it does seem like they've developed the capacity to "have" emotions to a first approximation, because it is quite helpful to model the way those emotions would affect the people who wrote their training data.

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

Comment Back to the days of anagrams. (Score 1) 97

Historically, when someone was afraid of being "scooped" on an announcement they hadn't adequately polished, they would instead write a quick and dirty (and usually long-winded, because editing takes time) summary of their work—and then release an anagram of said summary. That way they could prove later that they had, in fact, gotten there first. Nowadays I expect we would use a hash function instead of an anagram, but the same idea applies. Put your idea in tangible form, even if the description sucks. Maybe you won't have to release it, but if someone else then tries to undercut you by throwing millions of dollars of tokens at the same problem, you can still show that you got there first.

It's unfortunate that it has come to this, but it's not a novel problem. Annoying and unsatisfactory solutions already exist.

The problem here is that when you turned on the TV for the first time and clicked the 'I accept' button, you agreed to the recording, and probably agreed that you'd be responsible for letting anybody else who might be in range of the TV know that they're subject to recording.

Is that going to hold up in court? Who knows, but can you afford to spend the money to find out? Somebody eventually will, and you'll get a coupon for twenty bucks off of a new TV as the settlement.

you imply some importance to social media that I just don't understand. It is a service, if you don't like it go else where or do without. I don't see anywhere a right to Facebook and endless selfies. I don't see FB entitled to anything, they are earning their profit hand over foot because morons just seem to want to give them money and tell them everything about themselves. We're at a point where we need to decide some personal responsibility. Sadly most of our race needs a guardian entity looking out for them. If our recent generations were responsible for colonizing America , we'd all still be in WV taking selfies.
