Submission + - Scientists Turn Plastic Waste Into Edible Cookies (futurism.com)

fjo3 writes: In the event we turn all arable land on this planet into a barren heath incapable of growing food, humankind may have to resort to reaping what we sowed by eating our own plastic pollution.

A team of researchers at Southern Illinois University Carbondale just demonstrated that this was possible by using specially engineered yeast to create tasty — and yes, edible — cookies which they 3D printed out of plastic waste.

The yeast breaks down the components of plastic compounds and agricultural byproducts like discarded plant stalks into proteins, fats, acids, and flavorings that we can eat. When these are combined together, the mixture is fed into a 3D printer that spits out cookies of any desired shape.

A year's delay?

It's August 24th right now. "February or March" is around 5 months away. Which is not a year.

For weather?

Due to weather, yes, plausibly. This is literally rocket science and weather can absolutely merit a scrub.

And lighting on the moon.

Again, this is rocket science. The rocket scientists seem to think that visible light is somehow helpful to the landing's odds of success. It passes the sniff test to me; voluntarily sacrificing such a useful spectrum seems unwise to me.

Really?

Indeed, yes. Do you have some grounds for your doubt?

'They were against AI, and I'm like, 'OK, you sound like the person that would have been against the drum machine when it came out.' Or synthesizers, right?"'

Yup. I prefer music made by humans, preferably with analog instruments mostly made out of wood and metal.

Nothing wrong with music made by machines if you like that sort of thing, and if you're trancing out on the dance floor it might be perfect. But that's the problem for me, it's too perfect.

Humans on analog instruments make tiny variations in rhythm, pitch, timbre, etc., that usually correspond to the emotion or intent behind the music. This creates music that breathes, that hits you on more levels than just the beat and the melody.

Yes, you can imitate that with programming or AI, but a real musician gives you a sense of the personality and mood of the performer. To me that's the good stuff.

That's interesting but drum machines and synths are still instruments in a human's hands. Think about some of Pink Floyd's early works where they used tape loops and whatnot. The automation became an instrument to incredibly ground-breaking effect. Think about the entirety of Depeche Mode's discography. Huge amounts of artificial instruments but the arrangement can be very good, and they have made new arrangements throughout the decades when touring, just like purely accoustic bands. Then there's Michael Cretu's band, Enigma, which is literally a portable sound studio, yet his stuff is quite influential and complex.

The difference in my mind is that AI isn't any of those things. It's recombinant, not creative. It will never invent... until true AI in the sense we used to use the term exists.

Submission + - OpenAI and Google Move Into K-12 Classrooms with New Kid-Friendly AI Offerings

theodp writes: "OpenAI announced on Tuesday 'ChatGPT for Teens'", the NY Times reports, "a new mode in which the chatbot automatically limits some conversations to better protect young users, as scrutiny grows over the harmful effects of artificial intelligence." OpenAI added that it's also teaming with tech-backed nonprofit CodeAI to 'prepare the first AI generation', announcing a 'signature partnership' that it says will "give students and educators access to tools and resources that will help them learn how to use and benefit from AI [...] helping teens understand how AI works, direct it, question it, and create with it—with teachers playing a meaningful role in shaping how AI enters the classroom." Separately, CodeAI said it and OpenAI will be "helping students build foundational AI literacy" via the Hour of AI, through which it said "OpenAI and CodeAI will introduce millions of students to the basics of using AI thoughtfully and responsibly."

OpenAI's ChatGPT for Teens announcement came just days after the NY Times reported that Google turned on Gemini AI for K-12 students using its Google Classroom, a learning management system for posting assignments and turning in schoolwork that's used by 150+ million students and teachers worldwide. A new Gemini tab within Classroom will allow students of all ages to seek AI help on math problems and writing assignments. They can also generate course aids like study guides, quizzes and flashcards, as well as produce images. Last September, Google CEO Sundar Pichai briefed the White House on the tech giant's efforts to get Gemini for Education in 'every high school in America', which he noted "includes $3 million to Code.org [since rebranded as CodeAI] to transform its [K-12] curriculum and integrate new AI features." And in December, Google.org kicked off the inaugural 'Hour of AI' by announcing "over $5 million in new Google.org funding to bolster computer science teaching in the age of AI." The 5-day event during CS Education Week saw 13+ million schoolkids take AI tutorials, including Google's AI Quests offering.

The moves by Google and OpenAI in advance of children's return to classrooms for the 2026-27 school year further escalate the race among U.S. tech giants to train students on their AI tools. They also come just ahead of next month's release of NYT journalist Natasha Singer's Coding Kids: Big Tech's Battle to Remake Public Schools, "the inside story of how Big Tech catalyzed, co-opted, and ultimately came to capture computer science and AI education in America."

Task Manager is for application performance. It tells you what resources a given task/PID/application is using. It tells you what memory usage is, CPU usage is, GPU usage is, per application. Extending this to NPU hardware is very much the purview of Task Manager.

Dumb answer. Perfect shouldn't be the enemy of good enough, and a 0.02% failure rate is good enough *provided the application of additional checks and balances makes that failure rate have no consequence to the end users*

There's no such thing as perfect.

I never demanded perfection.

Worse, your qualification is meaningless. A 100% failure rate would be good enough provided additional measures that compensate for it.

This thing screws up one in every 5,000 visitors. Look up Sainsbury's. Three million customers per day. That's 600 failures per day. With around 1,500 locations, that's an average failure at every location every two to three days. Maybe that's happening when your best manager is on-hand to take a look and conclude "huh, well, this looks a lot like the known shoplifter but... well... maybe not". Or maybe that's happening in the middle of the night when your minimum-wage student decides to not serve a lawyer, doctor, or garbageman who deserves it.

A screwup once a year per location would be high. Once or twice a year for the entire chain... maybe. Maybe acceptable. But you go ahead and set your personal bar wherever you want. Until you get the cops called on you.

"Sainsbury's head office apologised to Arnold the next day and has paused use of its AI-assisted Facewatch technology in the store while an investigation takes place."

What investigation? It has a 0.02% failure rate, which is very, very high. End of investigation. Discard the tech.

"The incident was caused by human error, not the facial recognition technology. Customers can be reassured that the Facewatch system has a 99.98% accuracy rate, and every match is reviewed by a trained manager."

Every match may or may not be reviewed by a trained manager, but customers cannot be assured of anything except that they - per factual evidence - be wrongfully accused of wrongdoing. The incident would not have occurred had the facial recognition technology incorrectly targeted the wrong individual. The technology is the only place where blame should be assigned except for the executives who authorized its use and continue to make excuses for it.

"A Facewatch spokesperson said their technology was not at fault in this case. 'A correct alert was sent to the retailer, but was subsequently subject to human error in the way it was handled in store,' they said."

Facewatch is incorrect. Again. An incorrect alert was sent to the retailer... unless they are insisting Matt Arnold is in fact a shoplifter. There is no human error if there is no incorrect alert.

I do understand that lacking this technology, we would be solely relying on humans to notice things like repeat offenders. Same for automated license plate readers... we'd be solely relying on humans to spot, recognize, and act on suspect vehicles. But the sheer bulk of hits makes all the difference in the world. Humans will rely on the machine's judgement and the onus then shifts to the target to try to override that. If a store manager just randomly mistakes a legitimate customer for a shoplifter, it's much easier to convince them they've made a mistake.

Submission + - New Gel Regrows Tooth Enamel (sciencedaily.com) 2

fahrbot-bot writes: ScienceDaily is reporting that researchers have developed a fluoride-free gel that could help rebuild damaged tooth enamel, something the body cannot naturally replace once it is lost. Inspired by the proteins that guide enamel formation in infancy, the gel fills microscopic cracks, acting as as a framework, and draws calcium and phosphate from saliva to grow a new mineral layer that closely matches healthy enamel.

The material draws calcium and phosphate ions from saliva and uses them to guide the controlled formation of new mineral crystals. This process is known as epitaxial mineralization. In simple terms, the new crystals grow in alignment with the tooth's existing structure, allowing them to connect with the natural tissue beneath them rather than forming a separate, poorly organized coating.

According to the researchers, this organized growth helps the repaired surface recover both the microscopic architecture and the physical properties of healthy enamel.

In addition, when applied to exposed dentine, the gel can grow an enamel like mineral layer over the surface. This could help reduce tooth sensitivity while also creating a stronger surface for dental restorations to bond to.

The researchers tested the regenerated material under conditions intended to reproduce the stresses teeth experience in daily life. These included repeated brushing, chewing forces, and contact with acidic foods that can gradually dissolve enamel.

The results showed that the restored tissue displayed mechanical behavior similar to that of healthy natural enamel, suggesting it may be durable enough for practical dental use.

In lab tests on human teeth using human saliva, the process took about 24 hours for the initial crystallization, reaching 80% of the enamel's original strength in 2 weeks. Human trials have recently begun.

The study is published in Nature and also discussed on Instagram.

I don't think my omission or your list of new features, actually makes a significant difference.

All of the new "feature" you mention, had functional equivalents back in 1998. Why should Win98 support IPv6 when that standard wasn't even released until 1998, and nobody was using it? I'd say the same for your other "more" functionality. Yes, in a pedantic way. In a practical way, those things weren't included for the same reason TVs didn't support 4K back then.

Riiiiight. New features aren't new because they didn't exist before they existed. Sure.

Windows 98, 28 years ago, cost $209. https://news.microsoft.com/sou... Accounting for inflation, that would be $428 in today's dollars.

The summary doesn't mention this, but the article says the price of the home version of Windows 11 now costs $139. Maybe that's up from what it was, but way, way down from a long-term perspective.

Yup. A little Google tells us an OEM Win11 home is between $120 and $140 US today. An OEM Win 98 license in 1998 was between $50 and $70 USD. That's between $100 and $143 in today's dollars.

So yeah, the average price has crept up a bit. But we also can't ignore that you got less functionality in the box with Win98, even if we don't necessarily like some of what's in Win11.

So this plane flew for 27 minutes 1,100 feet above the ground? Why not higher?

I'd go with "because your first flight is a proof-of-viability experiment not a test-to-destruction flight".

(Because it's safer to fall out of the sky at 1,100 feet than at 30,000, LOL?)

Literally, yes. You'd want to test things like gear retraction and extension and confirm general flight-worthiness before you're testing cabin pressurization.

I wonder how practical it is extrapolate real flight times from such a low-flying example?

You probably wouldn't. That kind of information comes from airframe modeling, I'm sure. This kind of flight is about confirming you don't have obvious mechanical defects and a little bit of confirming performance values you already know.

Do you burn same energy at 30,000 feet as 1,100?

No. Less. There's less resistance at altitude which is exactly why long-range aircraft do it.

How much energy would have been consumed trying to get this plane up to 30,000 feet compared to 1,100 feet?

Don't know. Sorry.

Seems like they want to treat a very special test case (aloft 27 minutes) with an actual, practical flight, or are EV airplanes going to fly at 1,100 feet?

Maiden flight on a demonstrator aircraft. I have no idea what the production airframes expected five years from now are going to be doing but I'm almost positive they won't be that low. A random single-engine Cesna cruises upwards of 10x that.
