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 + - Houston man arrested for threatening Gov. Abbott's office over anime (abc13.com)

alternative_right writes: A man from Houston was arrested and charged after making terroristic threats to Gov. Greg Abbott's office in July, court records show.

The court documents show that the threatening voicemail was apparently about anime and the recent Texas law requiring age verification for certain websites, such as pornographic and obscene content. The voicemail to the Governor's Constituent Communications line read in part:

"I don't know which one of you sons of (expletive) passed this (expletive) bill to get this damn (expletive) blocking my (expletive) anime, but you whole (expletive) (expletive) need to unpass this (expletive). Y'all are (expletive) ridiculous with your (expletive) (expletive). My Google account says I'm (expletive) over the age of 18, and your (expletive) is passing these (expletive) laws. I'm a (expletive) stab every (expletive) one of you (expletive). Unlock my (expletive) anime."

Submission + - Times Magazine now serves ads that only AI chatbots can see (theregister.com)

Submitted by mccalli
mccalli writes: Times Magazine has started serving adverts with 'brand messages' to AI crawlers, which are not part of its main page. The aim seems to be to influence the chatbots to talk about the brand offerings in a positive light that can't be traced back to the actual page. Notably they've excluded Google chatbots from this, likely because Google penalise companies that show different search offerings to their bots vs actual human visitors.

Submission + - Veridenz Uses Nostr To Verify That Photos Have Not Changed (nerds.xyz)

Submitted by BrianFagioli
BrianFagioli writes: Slashdot reader Brian Fagioli has released Veridenz, an iPhone app that creates a cryptographic witness for photos without uploading the original image. The app hashes the file, signs the hash using a dedicated identity stored in Apple Keychain, and publishes the witness to Nostr relays while keeping the photo inside the app unless the user chooses to export it.

Rather than trying to determine whether a scene was genuine, Veridenz answers a narrower question by verifying whether a photo file matches the one that was originally witnessed. Users do not need a Nostr account because the app creates its own signing identity, keeping private documentation separate from a public Nostr profile.

Submission + - Waymo CEO explains why Tesla's camera-only self-driving falls short (electrek.co)

Submitted by AmiMoJo
AmiMoJo writes: Waymo co-CEO Dmitri Dolgov laid out the clearest technical case yet for why cameras alone can’t take a self-driving system to full autonomy, arguing that “weak sensing” hits a safety ceiling long before it reaches superhuman performance. He never said the word Tesla. But camera-only is Tesla’s entire bet, and this was a direct shot at it.

“Humans of course can drive with just eyes, so there’s that proof of existence,” he said. “If the goal were to just approximately match human performance or to build an assist product, that’s a very reasonable way to go.” Then the catch. If you’re targeting full autonomy and strongly superhuman performance, he said, “you find that weak sensing just leads to a safety curve that flattens out way too early.”

Submission + - France: RT journalist poses a serious threat to public order

An anonymous reader writes: Who Is Xenia Fedorova? France Expels Former RT France Head Accused of Spreading Kremlin Propaganda

France has ordered the deportation of journalist Xenia Fedorova, who has been accused of spreading Russian propaganda. In 2017, shortly after his election, President Emmanuel Macron refused to acknowledge Fedorova as a journalist. Now, the country has ordered her to leave for amplifying Kremlin narratives.

The French Interior Ministry said that Fedorova's continued airtime serves to 'undermine the interests of the state' and her continued stay in the country 'constitutes a particularly senior and current threat to public order.' Fedorova is currently on house arrest and is ordered to report to a police station every day.

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.

Submission + - Trump administration drafting ban on Chinese data center devices (yahoo.com)

Submitted by schwit1
schwit1 writes: The Federal Communications Commission, which oversees the U.S. telecom industry, is working on the measure to bar imports of new Chinese optical transceivers, which allow data to travel over fiber-optic cables at the speed of light within data centers. Officials hope to publish it this year, when it would take effect.

The move, not previously reported, aims to prevent Chinese firms from stealing data, installing malware or disrupting service at U.S. data centers, which house the chips to train and run AI models.

The FCC could still modify or shelve the restriction, the sources stressed, speaking on condition of anonymity to discuss sensitive matters. But it is the latest example of the Trump administration trying to limit Chinese technological incursions into cutting-edge U.S. industries before they become embedded in the supply chain.

"Transceivers definitely pose a risk," said Divyansh Kaushik, an AI policy expert at Washington, D.C., advisory firm Beacon Global Strategies. "As the data center buildout scales up, you want to make sure the data center supply chain is secure from the get-go," he added.

A U.S. ban on new models of Chinese data center devices would likely hit China's Zhongji Innolight, one of the biggest global sellers of transceivers, which was added to the Pentagon's list of alleged Chinese military-backed companies in June. The list can be a harbinger of tougher action. Innolight did not respond to requests for comment.

A ban could also raise costs for American cloud firms such as Amazon Web Services, as it may force them to transition to other producers such as U.S.-based Coherent and Lumentum.
