Submission + - Flock Has a Powerful New AI Tool for Police. We Got Its Code (archive.ph) 1

Submitted by fjo3
fjo3 writes: Vehicle surveillance giant Flock Safety has told the public for years that its technology “cannot recognize, identify, or track individuals.” It has now built a system that does both, an artificial intelligence tool for police that can identify drivers and track vehicles by their patterns of movement alone, WIRED has learned.

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

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.

Fixed cameras are easily avoided by someone looking to commit a crime. It's not hard to map out the cameras and calculate blind spots, or to disguise yourself such that the captured footage is useless for identifying you.

A live guard can move around, and will also easily identify someone who's taken measures to obscure their face.

A current robot is somewhere between, it's basically a mobile camera so it's less predictable/avoidable than a fixed camera, but not as good as a live guard. They're limited by laws currently, otherwise you could build a terminator/robocop style robot that was armed. Now that absolutely would deter/stop crime.

They do not do network level OS fingerprinting. If you were to do that then you would find the vast majority of hosts are linux - because very few windows systems are not behind a firewall, and most firewalls are linux based.

They are reading the user-agent header from web browsers.

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.

Submission + - Artificial Intelligence used to design brand new viruses (bbc.com)

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.
