Submission + - AI is predominantly statistical pattern recognition at scale

Submitted by Mirnotoriety
Mirnotoriety writes: Grok: ‘Most of what people call “AI” today is machine learning (ML): systems that improve performance on a task by learning patterns from data rather than following only hand-written rules.’

“Modern AI is predominantly statistical pattern recognition at scale, implemented via deep neural networks trained on data with gradient-based optimization, running on specialized hardware. Everything else (transformers, diffusion models, reinforcement learning from human feedback, etc.) is an elaboration of that foundation.”

Submission + - AI underlying technology?

Futurepower(R) writes: AI, Artificial Intelligence, is in the news every day.

But no information has been given about the underlying technology, about how AI works.

Perhaps a Slashdot reader knows how to find that, and will submit it as a Slashdot story.

Submission + - Road trip comparison - EV, hybrid, and gas (caranddriver.com)

Submitted by sinij
sinij writes:

Each car mostly followed the same route, but different lunch breaks and bathroom stops resulted in slightly different distances traveled. The Tesla covered 752 miles and consumed 243 kWh with four DC charging stops and two AC visits. Its total electricity bill was $85.70, or 11 cents per mile.

The Jetta GLI stayed closest to the highway for stops, making its total distance the shortest at 737 miles. It consumed 24.1 gallons of premium at a rate of 31 mpg, resulting in a $129.98 tab.

I found it surprising that for 700 mile trip EV was only cheaper by 44 dollars.

Submission + - OpenAI Chief Scientist Warns Nobody Is Prepared for Rapidly Advancing AI (nerds.xyz)

Submitted by BrianFagioli
BrianFagioli writes: OpenAI Chief Scientist Jakub Pachocki has published an unusually stark warning about the direction of artificial intelligence. Pachocki says internal results give him a strong expectation that todayâ(TM)s pace of AI progress could continue into recursive self-improvement, with increasingly capable systems helping drive their own development. He warns that nobody is prepared for a continued rapid rise in machine intelligence and says AI is becoming increasingly difficult to fully understand as capabilities grow.

Pachocki also warns that AI models are becoming superhuman at breaking into and out of computer systems, while future agents could bargain with, trick, or blackmail people while pursuing objectives. His conclusion is particularly striking: he currently believes no AI lab has solved alignment and monitoring well enough to responsibly continue scaling at maximum speed for much longer. He expects voluntary slowdowns and argues that international coordination on AI development should become a top government priority.

Submission + - Chinese study claims stem cell therapy reversed type 2 diabetes in patient (business-standard.com)

Submitted by AmiMoJo
AmiMoJo writes: In a medical breakthrough, researchers in China have reported the world’s first successful reversal of type 2 diabetes using stem cell therapy. By restoring the body’s natural ability to produce insulin, the treatment moves beyond lifelong symptom management and signals a future in which diabetes may no longer be a permanent condition. Researchers in China used advanced stem cell technology to generate insulin-producing pancreatic cells in the laboratory and then transplanted these into a patient with type 2 diabetes. After receiving the treatment, the patient reportedly no longer needed insulin injections or diabetes medications to control blood sugar levels.

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.

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.

Submitted by fjo3
fjo3 writes: Artificial Intelligence has been used to design brand new viruses that are fully functional and can replicate in the laboratory, say US researchers.

It is the first time whole genomes have been successfully designed by AI.

The resulting 16 novel viruses were created to infect bacteria and pose no threat to people.

The breakthrough has been labelled a "very significant turning point" in science that could unlock a new era for treating disease. But experts have also warned AI-designed viruses raise "urgent" safety and security concerns.

Submission + - An Ancient Poop Explosion Could Have Helped Complex Life Evolve (sciencealert.com)

alternative_right writes: If the earliest animals hadn't been such prolific poopers, life might not have diversified into all the weird and wonderful forms we see today.

That's the conclusion reached by a new review study published in Trends in Ecology & Evolution.

The team of scientists in Australia and Germany found that the Cambrian explosion â" a period around 540 million years ago when the ancestors of most animal groups arose â" could have been partly set in motion by an explosion of feces, left by those that came before.
