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

Submitted by fjo3
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.

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

Submitted by theodp
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."

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

Submitted by fahrbot-bot
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.

Even if they don't pollute all the time, consider when a "power emergency" will be most likely. One common situation is when there is a stagnant heat dome sitting on the area forcing everyone to crank up their A/C.

Then the data centers will fire up their gas and diesel generators with short exhaust stacks, and with no wind all those fumes will just linger in the general vicinity.

Gee, if a counterfeit lithium ion battery peddled by Amazon burns your house down, you get to sort it out in small claims court.

Or else let some guy whose salary ultimately comes from Amazon decide whether they're liable.

If 1,000 Kilowatts only costs "about $5", that puts each Kilowatt at about 1/2 cent? Seems kind low...

Time to turn in your geek card. A "watt" is a unit of *power*. People pay for *energy*. Energy = power X time.

Electricity is often sold in energy units called kWh (which is 3.6 megajoules). At a retail price of 20 cents/kWh, five dollars of electric ital energy is 25 kWh.

With a power consumption rate of 1000 kW, that amount of energy is used in 90 seconds. Presumably, the 1MW peak power rate was only used briefly, just like a car with a 300hp peak power engine usually cruises around only generating a couple of dozen hp.

It's not a remotely level playing field. One soldier who took part in the Venezuela raid basically had orders in hand when he placed multiple bets on the timing of the raid, netting a ton of money. There have been many other examples of inside information being used to stack the odds.

Unless you're a C-level employee, specifically working in M&A, or maybe as the lead on a truly revolutionary new product (no, your company's Facebook wannabe or thinly disguised open source ripoff ain't it) - You have no insider information to trade on. Sincere belief that your employer's cool new toys are going to change the world ain't it - every company has cool new toys in the pipeline, and most of them are going to flop or at best be just another branded widget.

This is absolutely not true. There are plenty of people in the financial side of a business that have information that is material but non-public, and trading based on that knowledge is illegal, including sudden cuts in spending, audit results prior to publication, and more. HR will be aware of major layoffs. Facilities might be aware of impending site closures before they're announced. All these things can be used for insider trading.

Lower-level people aren't usually pursued because they're small enough to fly under the radar. But that doesn't mean it's not illegal, and it doesn't mean it never happens.

You're overthinking this.

Submission + - China-free batteries made from salt are finally here (msn.com)

Submitted by fjo3
fjo3 writes: U.S. startups are finally delivering something researchers have been working on for decades: a battery in which rare, hard-to-get elements are replaced with the same stuff found in ordinary table salt.

This tech has the potential to help every country on earth break its dependence on China for batteries, and the critical minerals that go into them.

Like any other battery, sodium-ion cells can store and release energy. They are initially being deployed where they’re needed most, in America’s power grid and fast-expanding crop of data centers. As in our homes, giving the grid or other infrastructure the ability to stockpile energy when it is cheap and plentiful, and discharge it when it is scarce, can increase reliability and lower the cost of electricity.
