Scientists have developed a vibrating pill that, when swallowed before eating, can create a feeling of fullness. The Guardian reports: The research, which has yet to be carried out in humans, shows that after 30 minutes of activity by the Vibes pill, pigs ate on average almost 40% less food in the following half hour than they did without the device, and gained weight more slowly. The Vibes name is an acronym derived from the pill’s full title — Vibrating Ingestible BioElectronic Stimulator. The work in pigs suggests the vibrations activate stretch receptors in the stomach, simulating the presence of food. This results in signals being sent to the hypothalamus in the brain via the vagus nerve, increasing levels of various hormones that give rise to a feeling of fullness and decreasing those that result in feelings of hunger.

“We envision the Vibes pill being ingested on a relatively empty stomach 20 to 30 min before anticipated meals to trigger the desired sensation of satiety early in the meal,â the team write, adding that when produced at scale, the cost of the pills is expected to be in the cents to one dollar range. The vibrations, which are powered by a battery encased in the swallowed capsule, can be triggered when stomach acid dissolves a membrane around the pill, or by a timer. The researchers say the pills, which are about the size of a large vitamin tablet, offer a non-invasive, temporary therapy, without the need for weight-loss surgery, and exit the body with other solid waste — meaning in humans they are flushed down the toilet. However they suggest it could be possible to develop pills that are implanted, or stay in the stomach, to reduce the need for people to repeatedly take them, should they require continuing therapy.

Longtime Slashdot reader FudRucker quotes a report from Study Finds: Researchers from Northwestern University, Boston College, and the Massachusetts Institute of Technology (MIT) have developed a new synaptic transistor that works just like the human brain. This advanced device, capable of both processing and storing information simultaneously, marks a notable shift from traditional machine-learning tasks to performing associative learning — similar to higher-level human cognition. This study introduces a device that operates effectively at room temperatures, a notable improvement over previous brain-like computing devices that required extremely cold conditions to keep their circuits from overheating. With its fast operation, low energy consumption, and ability to retain information without power, the new transistor is well-suited for real-world applications.

“The brain has a fundamentally different architecture than a digital computer,” says study co-author Mark Hersam, the Walter P. Murphy Professor of Materials Science and Engineering at Northwestern’s McCormick School of Engineering, in a university release. “In a digital computer, data move back and forth between a microprocessor and memory, which consumes a lot of energy and creates a bottleneck when attempting to perform multiple tasks at the same time. On the other hand, in the brain, memory and information processing are co-located and fully integrated, resulting in orders of magnitude higher energy efficiency. Our synaptic transistor similarly achieves concurrent memory and information processing functionality to more faithfully mimic the brain.”

Hersam and his team employed a novel strategy involving moire patterns, a type of geometric design formed when two patterns are overlaid. By stacking two-dimensional materials like bilayer graphene and hexagonal boron nitride and twisting them to form a moire pattern, they could manipulate the electronic properties of the graphene layers. This manipulation allowed for the creation of a synaptic transistor with enhanced neuromorphic functionality at room temperature. The device’s testing involved training it to recognize patterns and similarities, a form of associative learning. For instance, if trained to identify a pattern like “000,” the transistor could distinguish that “111” is more similar to “000” than “101,” demonstrating a higher level of cognitive function. This ability to process complex and imperfect inputs has significant implications for real-world AI applications, such as improving the reliability of self-driving vehicles in challenging conditions. The study has been published in the journal Nature.

An anonymous reader quotes a report from The Guardian: From empty glasses of sherry on the mantelpiece to sooty footprints leading to the bedroom door, evidence of Santa’s existence is clearly irrefutable. Yet most children will begin to question it at some point — and many parents anticipate this moment with dread. Now psychologists have identified the average age when Santa skepticism creeps in, and which children are at greatest risk of harboring negative feelings when it does.

While most adults have fallen for the myth that Santa doesn’t exist, many children still believe — even if the idea of a single individual visiting the homes of billions of children in a single night is at odds with their wider reasoning skills. Dr Candice Mills, a psychologist at the University of Texas in Dallas, US, and a Santa sceptic, said: “Children typically begin to distinguish fantasy from reality during the preschool years, but their belief in the existence of a singular magical Santa Claus often continues into middle childhood.” […] To better understand this shift from belief to disbelief and children’s experiences of it, Mills and her colleagues interviewed 48 six- to 15-year-olds who had stopped believing in Santa and 44 of their parents, plus a further 383 adults.

The research, which has not yet been peer reviewed, found that for most children, disbelief crept in gradually about the age of eight — although some three- or four-year-olds had convinced themselves that Santa wasn’t real, while other children believed in him until they were 15 or 16. In many cases, it was testimony from other disbelievers that finally crushed their faith. Mills said: “They may have had some skepticism based on logical reasoning — like how can Santa Claus really get around the world in one night? — but what pushes them over the edge is a classmate at school saying he’s not real.”

Apple is in negotiations with major news and publishing organizations (source paywalled; alternative source), “seeking permission to use their material in the company’s development of generative artificial intelligence systems,” reports the New York Times. From the report: The technology giant has floated multiyear deals worth at least $50 million to license the archives of news articles […]. The news organizations contacted by Apple include Conde Nast, publisher of Vogue and The New Yorker; NBC News; and IAC, which owns People, The Daily Beast and Better Homes and Gardens. The negotiations mark one of the earliest examples of how Apple is trying to catch up to rivals in the race to develop generative A.I., which allows computers to create images and chat like a human. […]

Some of the publishers contacted by Apple were lukewarm on the overture. After years of on-again-off-again commercial deals with tech companies like Meta, the owner of Facebook, publishers have grown wary of jumping into business with Silicon Valley. Several publishing executives were concerned that Apple’s terms were too expansive, according to three people familiar with the negotiations. The initial pitch covered broad licensing of publishers’ archives of published content, with publishers potentially on the hook for any legal liabilities that could stem from Apple’s use of their content.

Apple was also vague about how it intended to apply generative A.I. to the news industry, the people said, a potential competitive risk given Apple’s substantial audience for news on its devices. Still, some news executives were optimistic that Apple’s approach might eventually lead to a meaningful partnership. Two people familiar with the discussions struck a positive note on the long-term prospects of a deal, contrasting Apple’s approach of asking for permission with behavior from other artificial intelligence-enabled companies, which have been accused of seeking licensing deals with news organizations after they had already used their content to train generative models.

Longtime Slashdot reader theodp writes: Way back in September 2012, Microsoft President Brad Smith discussed the idea of “producing a crisis” to advance Microsoft’s “two-pronged” National Talent Strategy to increase K-12 CS education and the number of H-1B visas. Not long thereafter, the tech-backed nonprofit Code.org (which promotes and provides K-12 CS education and is led by Smith’s next-door neighbor) and Mark Zuckerberg’s FWD.us PAC (which lobbied for H-1B reform) were born, with Smith on board both. Over the past 10+ years, Smith has played a key role in establishing Code.org’s influence in the new K-12 CS education “grassroots” movement, including getting buy-in from three Presidential administrations — Obama, Trump, and Biden — as well as the U.S. Dept. of Education and the nation’s Governors. But after recent updates, Code.org’s Leadership page now indicates that Smith has quietly left Code.org’s Board of Directors and thanks him for his past help and advice. Since November (when archive.org indicates Smith’s photo was yanked from Code.org’s Leadership page), Smith has been in the news in conjunction with Microsoft’s relationship with another Microsoft-bankrolled nonprofit, OpenAI, which has come under scrutiny by the Feds and in the UK. Smith, who noted he and Microsoft helped OpenAI and CEO Sam Altman craft messaging ahead of a White House meeting, announced in a Dec. 8th tweet that Microsoft will be getting a non-voting OpenAI Board seat in connection with Altman’s return to power (who that non-voting Microsoft OpenAI board member will be has not been announced). OpenAI, Microsoft, and Code.org teamed up in December to provide K-12 CS+AI tutorials for this December’s AI-themed Hour of Code (the trio has also partnered with Amazon and Google on the Code.org-led TeachAI initiative). And while Smith has left Code.org’s Board, Microsoft’s influence there will live on as Microsoft CTO Kevin Scott — credited for forging Microsoft’s OpenAI partnership — remains a Code.org Board member together with execs from other Code.org Platinum Supporters ($3+ million in past 2 years) Google and Amazon.
