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 + - A fundamental flaw leaves LLMs strikingly vulnerable to attack (technologyreview.com)

Submitted by joshuark
joshuark writes: It is impossible to make large language models fully secure against hacks because of a fundamental flaw in how they work, a team of researchers argue in a paper presented at the International Conference on Machine Learning, a top AI conference, this month. The claim has huge implications for the safety of this technology.

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.”

Submission + - AI Companies Destroying Books At Scale (futurism.com)

nightflameauto writes: AI companies are purchasing books from pre-AI times. The claim is that those books are free from the defects of AI generated text, and therefore more valuable for ingestion into AI datasets. In order to accomplish this, they are tearing the books down to be scanned, then destroying them as the scans are completed. This includes rare and out-of-print books that may be some of the few copies of any given published work left in existence.

Submission + - Is Mark Zuckerberg Actually TRYING to Destroy Meta? (futurism.com)

Submitted by fjo3
fjo3 writes: Lately, it almost feels like Zuckerberg is trying to destroy his own company. He’s burning through mountains of cash in a desperate attempt to keep up in the AI race. Yet despite the untold billions it’s spent so far, it’s being destroyed by OpenAI and Anthropic. Its employees have even resorted to using AI models made by its competitors, a humiliating reality check for how far behind Zuckerberg’s efforts have fallen.

It’s also a financial nightmare. Capital expenditures have risen dramatically, erasing any appetite for Meta on Wall Street. Its stock price “has been dead money for more than a year,” as Yahoo Finance notes, as investors continue to debate whether Zuckerberg is chasing the AI industry as it careens off a cliff — or edging ever closer to an AI-fueled industrial revolution.

Submission + - Your Brain Can Rewire Itself to Allow True Multitasking (sciencealert.com)

Submitted by alternative_right
alternative_right writes: Our daily lives are built on multitasking, but are our brains actually doing two things at once, or just switching very quickly between them?

Well, it depends. The science shows it's the latter, for cognitively demanding work.

But in a new study published in the Journal of Cognitive Neuroscience, researchers from Georgetown University Medical Center in the US have revealed that we can put certain tasks on autopilot in a way that enables something closer to true multitasking.

Driving is the perfect example: When you take your test, your entire mental and physical energy is concentrated on executing the right combinations of movements and thoughts.

After a decade behind the wheel, the brain is no longer consciously thinking everything through in great detail.

Submission + - How Microsoft's "Little Workaround" Created a Major Pentagon Threat (propublica.org)

Submitted by joshuark
joshuark writes: ProPublica Reporter Renee Dudley heard Microsoft was running tech support for the U.S. Defense Department through China, the country’s biggest cybersecurity adversary.

The arrangement was called “digital escorting.” She thought it sounded like a conspiracy theory — until she started looking into it. This is the story of what she found and how her investigation changed government policy.

Microsoft is using engineers in China to help maintain the Defense Department’s computer systems — with minimal supervision by U.S. personnel — leaving some of the nation’s most sensitive data vulnerable to hacking from its leading cyber adversary, a ProPublica investigation has found.

The arrangement, which was critical to Microsoft winning the federal government’s cloud computing business a decade ago, relies on U.S. citizens with security clearances to oversee the work and serve as a barrier against espionage and sabotage.

National security and cybersecurity experts in the Trump administration contacted by ProPublica were also surprised to learn that such an arrangement was in place, especially at a time when the U.S. intelligence community and leading members of Congress and the Trump administration view China’s digital prowess as a top threat to the country.

Microsoft uses the escort system to handle the government’s most sensitive information that falls below “classified.” According to the government, this “high impact level” category includes “data that involves the protection of life and financial ruin.” The “loss of confidentiality, integrity, or availability” of this information “could be expected to have a severe or catastrophic adverse effect” on operations, assets and individuals, the government has said. In the Defense Department, the data is categorized as “Impact Level” 4 and 5 and includes materials that directly support military operations.

“If someone ran a script called ‘fix_servers.sh’ but it actually did something malicious then [escorts] would have no idea,” a former Microsoft engineer who worked on the escort system, told ProPublica in an email. That said, he maintained that the “scope of systems they could disrupt” is limited.

In an emailed statement, the Defense Information Systems Agency said that cloud service providers “are required to establish and maintain controls for vetting and using qualified specialists,” but the agency did not respond to ProPublica’s questions regarding the digital escorts’ qualifications.

It’s unclear whether other cloud providers to the federal government use digital escorts as part of their tech support. Amazon Web Services and Google Cloud declined to comment on the record for this article. Oracle did not respond to requests for comment.

A spokesperson for the inspector general — whose office is supposed to operate independently in order to investigate potential waste, fraud and abuse — told ProPublica they were not authorized to speak about the issue and directed questions to DISA public affairs.
