Submission + - New Gel Regrows Tooth Enamel (sciencedaily.com) 1
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.

...to make new factories.
Like imagine if it were possible to create new semiconductor factories, making chips en masse, -- you could perhaps do it in a BIIIG state with a lot of land. You could have a factory with like 100 million square feet. Wouldn't that be something?
Maybe we should have more factories.
If only there were a price incentive to do so.
Submission + - China-free batteries made from salt are finally here (msn.com)
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.

Aren't most of the stories written around these three rules about ambiguities and loopholes
Yes, and the point you quoted still stands, they are a starting point.
The always relevant XKCD comic explains it well enough: those laws in that order are essential as the starting point. Different order or missing entirely is guaranteed bad. But as pointed out through all kinds of science fiction writing, there are many ways we can understand they are insufficient.
Right now I'd agree they're exactly backwards, or as the XKCD comic described, on track to become a "killbot hellscape". We need even more rules and regulations than that, but as a set of fairly obvious first steps penned 80 years ago, they're pretty blatantly an essential first draft of baseline rules that are missing today.

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.

Yes but also no.
The regulation isn't about "taking a cut", but primarily about financial crimes like money laundering and insider trading. Generally there are age requirements, as minors can't buy stocks or enter into futures contracts, though custodial accounts where the minor is authorized to use it are allowed. Every transaction is also associated with registered brokerage companies, every transaction tied to a taxpayer ID and account information. To participate the government requires documentation with a full legal name and government issued ID, and assorted other information to verify the person's identity.
In regulated markets every step has a paper trail can be tied back to a responsible human, the person who could potentially be jailed or fined for financial crimes.
Submission + - A fundamental flaw leaves LLMs strikingly vulnerable to attack (technologyreview.com)
By taking advantage of this flaw, which concerns how LLMs identify who or what is giving them instructions, the researchers were able to make popular LLMs spit out information they had been trained not to provide, such as how to synthesize cocaine and how to sabotage a commercial aircraft’s navigation system.
“There’s a real probability that this is going to be a problem that’s fundamentally unsolvable,” says Charles Ye, an independent researcher and coauthor of the ICML paper.
Companies will typically hire teams of human testers to try to come up with novel attacks that break existing guardrails, a process known as red-teaming. Model makers also use LLM super-hackers (such as OpenAI’s GPT-Red) that find and exploit weaknesses in other models to automate parts of this process. The goal is then to take those attacks and train a new model to resist them and anything that looks like them.
The problem, says Jasmine Cui, another independent researcher and coauthor of the paper, is that the approach amounts to giving the models a list of things they shouldn’t do. But no list is exhaustive. “It’s like watching The Simpsons and they have Bart writing ‘I will not say something inappropriate to my teacher’ a hundred times,” she says. “And he still does things that are pretty crass anyway.”
The ICML paper describes attacks against several of OpenAI’s models, but Cui and Ye say that they have since seen similar results with models made by Anthropic, Alibaba, and DeepSeek.
Cui and her colleagues wanted to find out why an attack like chain-of-thought forgery was so effective. They suspected it had something to do with the mechanism that LLMs use to keep track of where their instructions are coming from.
But what Cui and her colleagues discovered is that LLMs are in fact very bad at keeping track of different roles. In a series of experiments that looked at what was going on inside a handful of different models, the researchers found that LLMs seem to identify the role of a specific chunk of text not by the tags around it but by the style of that text and the words it contains.
The upshot, the researchers claim, is that all an attacker needs to do to hack an LLM is write text that spoofs a certain role. And because roles are a fundamental part of how LLMs work, no amount of training will fully solve the problem.
Ye is worried that nobody is ready for what’s coming. “There’s going to be a huge economic incentive for people to do jailbreaks and prompt injections,” he says. The best defense could be to expect the worst. Organizations shouldn’t trust LLMs, and they should expect that anything done by agents could be unsafe, he says: “That’s not a great solution, but it just might be what we have to do.”
“It’s really incredible that these things are being deployed everywhere to control super-critical systems,” he adds. “There’s been no study of the fundamental science here. We’re all doing it ad hoc.”
