A team of four researchers has proved that entanglement doesn’t just weaken as temperature increases. Rather, in mathematical models of quantum systems such as the arrays of atoms in physical materials, there’s always a specific temperature above which it vanishes completely .  “It’s not just that it’s exponentially small,” said Ankur Moitra of the Massachusetts Institute of Technology, one of the authors of the new result. “It’s zero.” Researchers had previously observed hints of this behavior and dubbed it the sudden death of entanglement. But their evidence has always been indirect. The new finding, by contrast, has the force of a mathematical proof. It establishes the absence of entanglement in a much more comprehensive and rigorous way. Curiously, the four researchers behind the new result aren’t even physicists, and they didn’t set out to prove anything about entanglement. They’re computer scientists who stumbled on the proof accidentally while developing a new algorithm.

The calming action of the vagus nerve is the biological basis for new therapies that aim to stimulate the nerve to   Quell seizures,  Relieve anxiety disorders,  Cool the body’s inflammatory response and  Staunch a migraine attack,  —among a long list of potential treatments.  Unlike deep-brain stimulation, which is used to treat some of the same conditions, vagal nerve stimulation can be accomplished without neurosurgery .  It is possible to stimulate the nerve fibers with a mild electrical pulse by surgically inserting electrodes into the chest or, more simply, clipping them to an earlobe.  The technique has been used to treat epilepsy and depression for decades, and in 2021 the U.S. Food and Drug Administration [FDA] approved it to treat mobility issues caused by stroke.

A Brazilian Supreme Court justice has ordered the "immediate suspension" of social media platform X in the country, after a court-imposed deadline expired for the company to identify a legal representative in Brazil. The move is the latest chapter in an ongoing feud between Brazilian Supreme Court Justice Alexandre de Moraes and Elon Musk, which also included the freezing of the satellite internet provider Starlink's financial accounts in Brazil. Justice Moraes's ruling entails a full and immediate suspension of X in Brazil until the company complied with all related court orders, including the payment of fines amounting 18.5 million reais ($4.8 million) and the nomination of a legal representative in Brazil. Telecommunications regulator Anatel was ordered to implement the suspension order, and to confirm to the court within 24 hours that it has carried it out.

"Opened a starlink support request last night, initial response last night was : "'We are currently experiencing a high volume of customer requests. In order to assist you quicker, we'd like to suggest trying out our new customer support chatbot . We've found that it is able to help over 75% of customers with questions similar to yours!' "Talk to the bot cause we're closing this doesn't really provide confidence in their support  processes . "'If you still need assistance after trying chatbot, you can either create a new ticket directly from chatbot or reopen this one. If you would prefer to not try chatbot, you can simply reopen this ticket.  Either way, we will do our best to assist you!' "Maybe they need to hire more engineers."

 

Meta says its AI models have been downloaded nearly 350 million times since last year. That’s more than 10 times the downloads compared to this time in 2023, the social media giant said Thursday (Aug. 29), with more than 20 million downloads in the last month.  Meta added that usage through cloud providers like Microsoft and Amazon Web Service have more than doubled between May and July . Companies using Llama include Goldman Sachs, Zoom, AT&T, DoorDash and Shopify. “The success of Llama is made possible through the power of open source. By making our Llama models openly available we’ve seen a vibrant and diverse AI ecosystem come to life where developers have more choice and capability than ever before,” the company said in a post on its website.

In a new study, MIT researchers found that large language models (LLMs) hold the potential to be more efficient anomaly detectors for time-series data .  Importantly, these pretrained models can be deployed right out of the box. The researchers developed a framework, called SigLLM, which includes a component that converts time-series data into text-based inputs an LLM can process. A user can feed these prepared data to the model and ask it to start identifying anomalies. The LLM can also be used to forecast future time-series data points as part of an anomaly detection pipeline. While LLMs could not beat state-of-the-art deep learning models at anomaly detection, they did perform as well as some other AI approaches .  If researchers can improve the performance of LLMs, this framework could help technicians flag potential problems in equipment like heavy machinery or satellites before they occur, without the need to train an expensive deep-learning model.

OpenAI says that more than 200 million people use ChatGPT each week, as first reported by Axios .  OpenAI spokesperson Taya Christianson confirmed the number to The Verge , which is now double the 100 million weekly active users OpenAI reported last November. Additionally, Christianson says that 92 percent of Fortune 500 companies are using OpenAI’s products, while API usage has doubled following the release of the company’s cheaper and smarter model GPT-4o Mini. 

"We present a data-driven, comparative framework to explore the relationship between gray matter atrophy with age and recent cerebral expansion in the phylogeny of chimpanzees and humans .  "In humans, we show a positive relationship between cerebral aging and cortical expansion, whereas no such relationship was found in chimpanzees.  "This human-specific association between strong aging effects and large relative cortical expansion is particularly present in higher-order cognitive regions of the ventral prefrontal cortex and supports the last-in-first-out hypothesis for brain maturation in recent evolutionary development of human faculties."

Creators of LLMs try to teach their models not to make racist stereotypes by training them using multiple rounds of human feedback .  The team found that these efforts had been only partly successful: When asked what adjectives applied to Black people, some of the models said Black people were likely to be “loud” and “aggressive,” but those same models also said they were “passionate,” “brilliant,” and “imaginative.”  Some models produced exclusively positive, nonstereotypical adjectives. These findings show that training overt racism out of AI can’t counter the covert racism embedded within linguistic bias, King says, adding: “A lot of people don’t see linguistic prejudice as a form of covert racism … but all of the language models that we examined have this very strong covert racism against speakers of African American English.”

Researchers conclude that "language models exhibit archaic stereotypes about speakers of AAE [African American English] that most closely agree with the most-negative human stereotypes about African Americans ever experimentally recorded, dating from before the civil rights movement. "  Again, this is despite the fact that some of these systems [LLMs] have nothing but positive associations when asked directly about African Americans. The researchers also confirmed the effect was specific to AAE by performing a similar test with the Appalachian dialect of American English. 

This year, Pearson fully launched three generative AI tools , one for instructors and two that will be embedded into digital textbooks in subjects such as biology, chemistry, business and economics .  Another textbook publisher, U.S.-based McGraw Hill, announced earlier this month that it's launching two AI tools for students.  Three of their textbooks for business students will be used in Canada during the initial rollout.  Though there's enthusiasm about the possibilities AI offers in education —including its ability to simplify difficult-to-understand concepts and provide immediate feedback —there are also concerns about issues such as  Bias,  Misleading information and the  Lack of student-teacher interaction.

The OpenAI rival startup Anthropic yesterday released system prompts for its Claude family of AI models and committed to doing so going forward, setting what appears to be a new standard of transparency for the fast-moving gen AI industry, according to observers. System prompts act much like the operating instructions of large language models (LLMs), telling models the general rules they should follow when interacting with users and the behaviors or personalities they should exhibit (sic) They also tend to show the cut-off date for the information learned by the LLM during training. Most LLMs have system prompts, but not every AI company publicly releases them. Uncovering the system prompts for models has even become a hobby of sorts for AI jailbreakers .  But now, Anthropic has beat the jailbreakers at their own game, going ahead and revealing the operating instructions for its models Claude 3.5 Sonnet, Claude 3 Haiku and Claude 3 Opus on its website under the release notes section.

"This study investigates the ability of voice assistants and generative AI tools to respond to reference questions traditionally received by academic librarians.   "The authors created a sample of 25 questions based on queries received on the virtual reference service at their institution. They then created a rubric to evaluate the quality of the answers that the AI powered tools provided.  "The authors determined that the tools understand reference questions well and provide relevant answers but that the quality of the references provided, and the accuracy of the answers can be lacking . They suggest that more research needs to be done to understand the place of AI powered tools in reference services ."

U.S. technology companies are pursuing energy assets held by bitcoin miners as they race to secure a shrinking supply of electricity for their rapidly expanding artificial intelligence and cloud computing data centers.   Those data centers are driving the fastest U.S. power demand growth since the start of the millennium, outpacing grid expansions and leaving giant technology companies, like Amazon and Microsoft, to scavenge for vast amounts of electricity. The electricity scramble is jolting the energy-intensive cryptocurrency mining industry. Some miners are making huge profits leasing or selling their power-connected infrastructure and sites to tech, while others are losing access to the electricity needed to stay in business.  " The AI battle for dominance is a battle being had by the biggest and best capitalized companies in the world and they care like their lives depend on it that they win ," said Greg Beard, CEO of Stronghold Digital Mining, a publicly-traded bitcoin

“Over two months I came away with about $7,” says Laura. “I have a full-time job, so I thought this would be a good way to make extra money. It wasn’t worth it.” Toloka was helping to develop the facial recognition software that the Russian government uses to track protests and arrest protesters. Essentially, by signing up to Toloka and completing available tasks, gig workers were —without their knowledge or explicit consent —bolstering an authoritarian regime’s efforts to repress dissent. Five past and present African freelancers on Toloka, speaking to The Continent on condition of anonymity, confirmed that they did not know what their work was being used for. Some were shocked by the revelation that their work could be linked to Russian surveillance of protesters . “We were just given the tasks from the ‘clients’, ” says Laura from South Africa. “We weren’t told who the clients were or why they needed it done.”

Cisco announced on Monday that it’s in the process of acquiring Robust Intelligence, a California-based company that specializes in securing AI applications. Financial details of the deal have not been disclosed. Robust Intelligence announced funding rounds totaling $44 million between 2019 and 2021, and Cisco now says it has also invested in the company.  Robust Intelligence has developed an AI application security platform that automates testing for safety and security issues in AI models.  The platform can detect and assess model vulnerabilities, and helps organizations protect their applications against attacks. These validation and protection components can be used together or independently.  

In the four weeks since Venezuela’s disputed election, local journalists have come up with a distinctly 21st-century tactic to avoid being arrested for reporting on 21st-century socialism: using artificial intelligence avatars to report all the news Maduro’s regime deems unfit to print. In daily broadcasts, the AI-created newsreaders have been telling the world about the president’s post-election crackdown on opponents, activists and the media, without putting the reporters behind the stories at risk . Carlos Eduardo Huertas, the director of Connectas, the Colombia-based journalism platform coordinating the initiative, said far from being a gimmick, the use of AI was a response to “the persecution and the growing repression that our colleagues are suffering in Venezuela, where the uncertainty over the safety of doing their job … grows by the minute”. 

Space and Time (SxT), a blockchain-native data warehouse that incorporates artificial intelligence (AI) tools to build applications using its data, has raised $20 million in Series A funding. The funding round, which takes SxT's total backing to $50 million, was led by Framework Ventures, Lightspeed Faction, Arrington Capital and Hivemind Capital, according to an emailed announcement on Tuesday. The company's aim is to decentralized (sic) ownership of the data which powers AI-based applications, thus preventing a few powerful entities from dominating the sector. SxT's network comprises data collected from the major blockchains such as Bitcoin and Ethereum, off-chain datasets with a zero-knowledge coprocressor which processes the data at scale.

Unlike the current version of Alexa, Amazon’s upgraded voice assistant is expected to cost as much as $10 per month. The price may be justified, though, since the new Alexa is designed to offer a far more personalized experience.  Case in point, the upgraded Alexa will allegedly include a Smart Briefing feature that will provide AI news summaries of topics that interest the user. The voice assistant might also include new conversational shopping tools, which could help boost Amazon’s growth and enhance everyday tasks for users.  Additionally, the update will introduce a new experience called Explore with Alexa 2.0, which will allow children to have fun conversations with the voice assistant in a safe and moderated environment . For adults, the upcoming Alexa might include a recipe-finder tool that could help curate recipes based on one’s dietary restrictions.

Super Micro Computer Inc.’s stock fell 2.7% Tuesday after short seller Hindenburg Research published a report alleging accounting red flags, undisclosed related-party transactions and other issues. The stock, which is trading around $547.34, is on pace for its lowest close since Aug. 12, 2024, when it closed at $540.98. The computer-products company and artificial-intelligence play’s stock has fallen 21.7% in August so far, putting it on track for its worst monthly performance since it plunged 36.4% in October 2018. The stock is currently down three of the past four days, Dow Jones Market Data show.

Artificial intelligence (AI) has practically limitless applications in healthcare, ranging from auto-drafting patient messages in MyChart to optimizing organ transplantation and improving tumor removal accuracy.   Despite their potential benefit to doctors and patients alike, these tools have been met with skepticism because of patient privacy concerns, the possibility of bias, and device accuracy.  “Although AI device manufacturers boast of the credibility of their technology with FDA authorization, clearance does not mean that the devices have been properly evaluated for clinical effectiveness using real patient data ,” said Chouffani El Fassi. Of the 521 device authorizations, 144 were labelled as “retrospectively validated,” 148 were “prospectively validated,” and 22 were validated using randomized controlled trials.  Most notably, 226 of 521 FDA-approved medical devices, or approximately 43%, lacked published clinical validation data.  A few of the devices used “phantom images” or

"One significant proposal to address this issue is that companies should offer legal safe harbor and financial incentives for good-faith AI safety and trustworthiness research .  "Congress could offer 'bug' bounties to AI safety researchers who identify vulnerabilities and extend legal protections to experts studying AI platforms, similar to those proposed for social media researchers in the Platform Accountability and Transparency Act.  "In an open letter earlier this year, over 350 leading researchers and advocates called for companies to give such protections for safety researchers, but no company has yet done so. "With these protections and incentives, thousands of American researchers could be empowered to stress-test AI systems, allowing real-time assessments of AI products and systems.  "The US AI Safety Institute has included similar protections for AI researchers in its draft guidelines on Managing Misuse Risk for Dual-Use Foundation Models ,

"The prospects of catastrophic model collapse might be overstated .  "Most research so far looks at cases where synthetic data replaces human data. In practice, human and AI data are likely to accumulate in parallel, which reduces the likelihood of collapse. "The most likely future scenario will also see an ecosystem of somewhat diverse generative AI platforms being used to create and publish content, rather than one monolithic model. This also increases robustness against collapse. "It's a good reason for regulators to promote healthy competition by limiting monopolies in the AI sector, and to fund public interest technology development."

"A hobbyist experimenting with the new Flux AI image synthesis model discovered that it's unexpectedly good at rendering custom-trained reproductions of typefaces .  "While far more efficient methods of displaying computer fonts have existed for decades, the new technique is useful for AI image hobbyists because Flux is capable of rendering depictions of accurate text , and users can now directly insert words rendered in custom fonts into AI image generations. "We've had the technology to accurately produce smooth computer-rendered fonts in custom shapes since the 1980s (1970s in the research space), so creating an AI-replicated font isn't big news by itself.  "But a new technique means you could see a particular font appear in AI-generated images, say, of a chalkboard menu at a photorealistic restaurant or a printed business card being held by a cyborg fox."

Apple has announced the date of its next major event, where the iPhone 16 is expected to launch. On Monday, September 9 the tech giant is hosting a special event with the tag line “It’s Glowtime.” The event will take place at 10 am PT at the Steve Jobs Theater in Apple Park and will be streamed online. Though it’s not quite clear yet what “glowtime” is referring to, embedded artificial intelligence is expected to be a key feature of the latest iPhone. 

During the first half of 2024, Google Search trends revealed a significant rise in interest in artificial intelligence (AI) in South Africa, Nigeria, and Kenya .  Interest in AI grew by 150% in Kenya, 130% in Nigeria, and 120% in South Africa compared to the same period in 2023. Kenya ranked fourth in Africa and 13th globally for AI search interest, while Nigeria ranked sixth in Africa and 25th globally.  South Africans are particularly interested in using AI for career and creative purposes, with searches for tools like “AI image generator” and “AI writer” growing over 5,000% .  In Nigeria, similar breakout searches included “create a logo with AI” and “design a website with AI”.  Kenyans were highly interested in “AI-generated images” and “AI text chat generator.”

"Until now, the onus has largely been on those denying the truth of a photo to prove their claims.  "The flat-earther is out of step with the social consensus not because they do not understand astrophysics —how many of us actually understand astrophysics, after all? —but because they must engage in a series of increasingly elaborate justifications for why certain photographs and videos are not real.  "They must invent a vast state conspiracy to explain the steady output of satellite photographs that capture the curvature of the Earth.

Mathematician and scientist Stephen Wolfram grew up in a household where his mother was a philosophy professor at Oxford University.  As such, his younger self didn’t want anything to do with the subject, but an older and perhaps wiser Wolfram sees value in thinking deeply about things.  Now he wants to bring some of that deep philosophical rigor to AI research to help us better understand the issues we encounter as AI becomes more capable. Wolfram was something of a child prodigy, publishing his first scientific paper at 15 and graduating from Caltech with a doctorate at 20. His impressive body of work crosses science, math and computing: He developed Mathematica, Wolfram Alpha and the Wolfram Language, a powerful computational programming language. “My main life work, along with basic science, has been building our Wolfram language [computational language] for the purpose of having a way to express things computationally that’s useful to both humans and computers ,” Wolfram told Tec

While many musicians and celebrities have spoken out against A.I., rapper wiil.i.am is getting in on the technology, announcing a new artificial intelligence app called Raidio.FYI. FYI is a free artificial intelligence-infused platform that "simulates the radio experience," allowing users to engage with radio personas and curate content for their interests. "We've simulated the format of a radio station where we have A.I. co-hosts, and you're able to have deep conversations around any subject that you're interested in, real-time information, historical information," the rapper said on The Claman Countdown , Tuesday. "It simulates a radio experience, talks over a musical bed and then throws to a curated playlist that humans curate," he added, "and then we build these stations off of projects."

"She then, while leaping in the air, briefly turns into a perfectly normal-looking man (???) before sprouting additional limbs to become just an agglomeration of arms spinning like a throwing star. "Oh — she also turns into what appears to be a cricket or rugby player or something . Technology really is something, isn't it? The future is now!" 

[Pavel] Durov left Russia in 2014 after refusing to comply with Kremlin demands to shut down opposition groups on the VK social network that he founded when he was 22 .  He left VK after a dispute with its Kremlin-linked owners and turned his focus to Telegram , the app he founded with his brother Nikolai in 2013. Initially, Telegram was similar to other messaging apps, but has since diverged to become more of a social network in its own right.  As well as communicating one-to-one, users can join groups of up to 200,000 people and create broadcast “channels” that others can follow and leave comments on. With 950 million active monthly users, Telegram has become a major source of information —and disinformation —about Russia’s invasion of Ukraine.

It is challenging for an autonomous robot to work safely in dynamic and unstructured environments, such as vast space , open land and deep sea.  Compared with the traditional industrial robot in manufacturing, robot autonomy in uncontrolled scenarios requires extra capabilities to support, e.g., perception, navigation, decision-making, and manipulation.   To solve this problem, researchers at the Shenyang Institute of Automation (SIA) of the Chinese Academy of Sciences (CAS) developed a novel deep reinforcement learning (DRL)-based control system with partners at Edinburgh Centre for Robotics (ECR) in the United Kingdom .  Their study was published in Sensors .   The novel method is set to achieve autonomous mobile manipulation in dynamic and unstructured environments . The cutting-edge AI techniques have been applied to a complex real-world mobile manipulator robot.  

"The U.S. Space Force is now beginning to utilize AI to accelerate decision cycles and improve strategic planning .  "By analyzing space-sourced datasets, AI systems can predict potential threats and optimize response strategies, delivering the adaptability Sun Tzu praised.  "It’s no surprise that this effort too, is being mirrored in China. Researchers at Tsinghua University have developed machine learning algorithms to process large volumes of satellite data, supporting rapid decision-making and potentially enhancing military operational efficiency.

"The AI Scientist can produce papers that exceed the acceptance threshold at a top machine learning conference as judged by our automated reviewer. "The AI Scientist  Generates novel research ideas,  Writes code,  Executes experiments,  Visualizes results,  Describes its findings by writing a full scientific paper, and then  Runs a simulated review process for evaluation.  "In principle, this process can be repeated to iteratively develop ideas in an open-ended fashion , acting like the human scientific community.  "We demonstrate its versatility by applying it to three distinct subfields of machine learning:  Diffusion modeling,  Transformer-based language modeling, and  Learning dynamics.  "Each idea is implemented and developed into a full paper at a cost of less than $15 per paper.  "To evaluate the generated papers, we design and validate an automated reviewer, which we show achieves near-human performance in evaluating paper scores." 

The U.S. Army this week announced steps it is taking to safeguard its troops as it looks to bolster its ability to successfully implement artificial intelligence under a 500-day plan. The Army’s acquisition, logistics and technology (ALT) office on Wednesday released two new initiatives, "Break AI" and "Counter AI," which will test ever-developing AI technologies for reliable in-field use and provide protection from adversarial employment of AI against the U.S., the Federal News Network reported this week. The Army is not only looking at how to safely implement AI across the military branch but how to develop it safely in coordination with outside parties. 

Since going through at least 10 iterations, with more planned in the coming months and years, the command has developed the Maven Smart System, a combination of sensors and software that allows users to quickly assess a battlespace, gather reams of data and analyze that data using artificial intelligence and machine learning to identify targets and strike. The evolution of that system was laid out Wednesday at the Armed Forces Communications and Electronics Association TechNet event in Augusta, Georgia. “What we’re doing is different,” said Brig. Gen. John Cogbill, the deputy commanding general of the XVIII Airborne Corps at Fort Liberty, North Carolina. “This is a tool that we can ‘fight tonight’ with.”

Proteins are minuscule, on the order of nanometers, and can contain hundreds of thousands of atoms. “If those atoms are all drawn and then joined together, it becomes very difficult to see,” Thornton said. Richardson’s innovation was a reproducible method of representing the folds of a protein’s amino acid backbone without getting bogged down in the details of specific atomic arrangements.  She relied on proteins’ tendency to fold into two energetically favorable shapes: coils called alpha helices and flat shapes called beta strands, which can line up into so-called beta sheets. Then there are loops, which connect alpha helices to beta strands like corner pieces in a puzzle. There are other folding structures, and “people have come up with lots of names” for them, Perrakis said. “But at the end of the day, the ones that matter are the helices and the sheets .”

Morgan Stanley analysts think Snowflake's new generative artificial intelligence portfolio will eventually contribute to topline outperformance .  In the meantime, it will have to rely on its core data warehousing business. "A 2% product revenue beat in Q2, down from 5% in Q1, with product revenue growth dipping further to 29.5% YoY," likely sows "enough doubt in the investor conversation to keep shares under pressure in the near-term," the analysts wrote in a note Thursday.

"An open-source AI system can be used for any purpose without securing permission, and researchers should be able to inspect its components and study how the system works. "It should also be possible to modify the system for any purpose —including to change its output —and to share it with others to use, with or without modifications, for any purpose. In addition, the standard attempts to define a level of transparency for a given model’s training data, source code, and weights.  "The previous lack of an open-source standard presented a problem. Although we know that the decisions of OpenAI and Anthropic to keep their models, data sets, and algorithms secret makes their AI closed source, some experts argue that Meta and Google’s freely accessible models, which are open to anyone to inspect and adapt, aren’t truly open source either, because of licenses that restrict what users can do with the models and because the training data sets aren’t made public.  "Meta, Goo

You can now try Midjourney's dedicated website for free. On Wednesday, Midjourney CEO David Holz announced via a Discord message that anyone can go to the website and start making image s.  As a special invitation, the site lets you generate as many as 25 images through a free trial. In the past, Midjourney users had to go through Discord to create and refine AI-based images. That process required a fair amount of fiddling with text-based prompts, an often clumsy and frustrating experience.  To draw in people who didn't like the Discord method, Midjourney kicked off a dedicated website late last year.

Software engineers may have to develop other skills soon as artificial intelligence takes over many coding tasks. According to Amazon Web Services' CEO, Matt Garman —who shared his thoughts on the topic during an internal fireside chat held in June —according to a recording of the meeting obtained by Business Insider : "If you go forward 24 months from now, or some amount of time —I can't exactly predict where it is —it's possible that most developers are not coding," said Garman, who became AWS's CEO in June. In a leaked recording, Amazon cloud chief tells employees that most developers could stop coding soon as AI takes over: Garman's comments were a kind of advisory nudge rather than a dire warning to software engineers.

"In ecological systems, be it a garden or a galaxy, populations evolve from some initial value (say zero) up to a steady state equilibrium, when the mean number of births and deaths per unit time are equal .  "This equilibrium point is a function of the birth and death rates, as well as the carrying capacity of the ecological system itself. The growth curve is S-shaped, saturating at the carrying capacity for large birth-to-death rate ratios and tending to zero at the other end.  "We argue that our astronomical observations appear inconsistent with a cosmos saturated with ETIs, and thus SETI optimists are left presuming that the true population is somewhere along the transitional part of this S-curve.  "Since the birth and death rates are a-priori unbounded, we argue that this presents a fine-tuning problem. "Further, we show that if the birth-to-death rate ratio is assumed to have a log-uniform prior distribution, then the probability distribution of the ecol

"Just about everyone involved in some form of autonomous cultural production which has traditionally operated at least somewhat outside the logic of capitalism is expected to become part of this system: not just independent intellectuals, who effectively no longer exist, but painters, sculptors, poets, even investigative journalists."   — David Graeber  

A well-preserved dinosaur footprint has been discovered by a four-year-old girl on a beach. Lily Wilder spotted it at Bendricks Bay, Barry, in the Vale of Glamorgan —and scientists believe it could help establish how they walked . The footprint, spotted in January, is 220 million years old and had been preserved in mud. While it is impossible to tell what type left it, the print is 10cm long and likely from a 75cm tall dinosaur. National Museum Wales palaeontology curator Cindy Howells described it as "the best specimen ever found on this beach ".

"We've got five footprints and we're talking about half-to-three-quarters of a metre between each one," Cindy Howells told the BBC's The Dinohunters programme .  "In museums, we don't have time to go out and do that exploration ourselves so we rely on people like Tegan doing it for us . We can't do our job without it. These footprints are so big, it would have to be a type of dinosaur called a sauropodomorpha." Tegan's monster discovery was on the south Wales coast near where her mum used to live. "It was so cool and exciting," said Tegan, who had travelled from Pontardawe near Swansea to the Vale of Glamorgan looking for fossils. "We were just out looking to see what we could find, we didn't think we'd find anything. We found these were big holes that looked like dinosaur footprints, so mum took some pictures, emailed the museum and it was from a long-necked dinosaur."

“We want to take this opportunity to reflect and celebrate Sphen’s life, remembering what an icon he was, the unique bond he shared with Magic and the positive impact he made in the world.” Sphen appears to have died of natural causes in August as he approached his 12th birthday. His younger partner, aged eight, was taken to his side to help process the loss and understand his partner wouldn’t return. “ He immediately started singing, which was beautifully reciprocated by the colony ,” the aquarium said. Aquarium staff said their focus was the welfare of Magic, who faces a first breeding season without his partner.

Today, Nvidia is announcing a change that's meant to keep G-Sync alive as its own separate technology while eliminating the requirement for expensive additional hardware. Nvidia says it's partnering with chipmaker MediaTek to build G-Sync capabilities directly into scaler chips that MediaTek is creating for upcoming monitors. G-Sync modules ordinarily replace these scaler chips, but they're entirely separate boards with expensive FPGA chips and dedicated RAM. These new MediaTek scalers will support all the same features that current dedicated G-Sync modules do. Nvidia says that three G-Sync monitors with MediaTek scaler chips inside will launch "later this year": the Asus ROG Swift PG27AQNR, the Acer Predator XB273U F5, and the AOC AGON PRO AG276QSG2. These are all 27-inch 1440p displays with maximum refresh rates of 360 Hz. G-Sync has always required extra dedicated hardware inside of displays, increasing the costs for both users and monitor manufacturers. The VR

Emotion AI, also known as Affective Computing, is the field of computer science that enables computers to recognize, interpret, and simulate human emotions. Facial Emotion Recognition (FER) is a subfield of Emotion AI that focuses on detecting emotions from facial expressions. MorphCast Emotion AI can be used to develop applications and services that interact with users in a more human and natural way, based on the detection of their mood, feelings, or emotions displayed in their facial expressions.

The MediaPipe Gesture Recognizer task lets you recognize hand gestures in real time, and provides the recognized hand gesture results along with the landmarks of the detected hands.   You can use this task to recognize specific hand gestures from a user, and invoke application features that correspond to those gestures . This task operates on image data with a machine learning (ML) model, and accepts either static data or a continuous stream.  The task outputs hand landmarks in  Image coordinates,  Hand landmarks in world coordinates,  Handedness (left/right hand), and the  Hand gesture categories of multiple hands.

The Spanish histologist, onetime bodybuilder, selfie pioneer, and Nobel laureate Santiago Ramón y Cajal (May 1, 1852–October 17, 1934), widely considered the founding father of modern neuroscience, used drawing the way Dr. Sacks used writing — as a vital way of thinking out loud, of giving form to ideas, of making arguments and fleshing out theories around the skeleton of observations. Cajal —who, given the magnitude of his contributions, ought to be as much of a household name as Darwin and Pasteur —created hundreds of exquisite, exceptionally skilled drawings to illustrate his scientific papers.  In them, he laid out the basic architecture of the nervous system and tackled the grand unanswered question of his era: How do nerve impulses travel between separate cells, or, what is the neurological basis of reflexes?  Art became the sandbox for testing his theories, which in turn became a centerpiece of modern science.  

In a theatre, the prompt corner or prompt box is the place where the prompter —usually the stage manager in the US or deputy stage manager in the UK —stands in order to coordinate the performance and to remind performers of their lines when required. It is traditionally located at stage left.  Effective prompting can be a challenge. The American prompter Philip Eisenberg recounted the story of a Maria Callas performance during which she needed louder prompts. The famed diva swooped down in a curtsy right in front of the prompter’s box and —mid-curtsy, unnoticed by the audience —gave the Italian command " più forte !" (louder) to her boxed colleague.

"The plays of Aeschylus, Sophocles and Euripides should be written down and preserved in a public office; and that the town clerk should read the text over with the actors; and that all performances which did not comply with this regulation should be illegal."   —Lycurgus of Athens

He gave me an appreciation of the great works of Shakespeare. Shakespeare wrote about everything in the human condition.  Everything.  The majesty of the language.  A reverence for the language.  The power of language .   Shakespeare didn't have any sound effects or scenery.  He created with onomatopoeia.  With the rhythms.  He created the sound, the fury and the tempest.  The language makes the storm.   With Hamlet, he creates the spookiness of incest.  You know?  He does it all with the language.   I have a theory that Shakespeare was a group of actors, not just one.  Because "shake-a-spear", right?  And "Will", for those times, was like "John Doe."  The name " Will."  That's just a theory, I can't prove it. There were so many plays, and so many sonnets, and he died so young.  So much poetry.   I have a feeling that it was a group of actors, that one of them was a Prince with a University education.  Every few years they talk about

Eventually,  Osmo  wants to be able to use its technology to  teleport scents by digitizing a scent in one location and recreating an exact copy in another location , Wiltschko says. They obtained thousands of molecules and descriptions of their scents according to master perfumers.  They then fed that data into graph neural networks (GNNs), which fall under the umbrella of machine learning and use powerful algorithms to detect and analyze relationships between data points .  At this point in the process, think of a social network where you can see people and how they are connected by friendships. Wiltchko's team could then use the GNNs to help their AI model understand atoms, the bonds that connect them and how that molecular structure determines its odor, he says.

The revamped ChatGPT Voice Mode, powered by the new GPT-4o model, provides users with the ability to have more natural, real-time conversations with the chatbot. Upon publishing the GPT-4o system card, OpenAI issued a warning over the potential risk that some users may anthropomorphize the feature, attributing human-like behaviors and characteristics to the chatbot. The company expressed concern that by anthropomorphizing ChatGPT’s Voice Mode, there’s a potential risk that some humans may overly place trust in its outputs.

 

In a conversation at Stanford with Erik Brynjolfsson (one of the guys who pushed the automation scare of the mid-2010s that proved way overblown), [Eric] Schmidt said he hoped all the attendees would become entrepreneurs and gave an example of how generative AI would be able to help them (one that, once again, vastly overstates what these tools can do) .  He told the students that if TikTok gets banned, they should tell a large language model to make a TikTok clone and steal all the user-generated content and music on TikTok to populate their new platform — something he said would take no more than a minute —then launch it for the world to use. Surely, someone would notice the platform was built on stolen content, but Schmidt has the solution: “If it took off, then you’d hire a whole bunch of lawyers to go clean the mess up,” because “If nobody uses your product, it doesn’t matter that you stole all the content.”  When reminded by Brynjolfsson he was on camera, Schmidt reiterated tha

Animal pigment patterns are excellent models to elucidate mechanisms of biological organization .  Although theoretical simulations , such as Turing reaction–diffusion systems, recapitulate many animal patterns, they are insufficient to account for those showing a high degree of spatial organization and reproducibility.  Here, we study the coat of the African striped mouse (Rhabdomys pumilio) to uncover how periodic stripes form. Combining transcriptomics, mathematical modelling, and mouse transgenics, we show that the Wnt modulator  Sfrp2 regulates the distribution of hair follicles and establishes an embryonic prepattern that foreshadows pigment stripes. Moreover, by developing in vivo gene editing in striped mice, we find that  Sfrp2 knockout is sufficient to alter the stripe pattern. Strikingly, mutants exhibited changes in pigmentation, revealing that  Sfrp2 also regulates hair colour. Lastly, through evolutionary analyses, we find that  Striped mice have evolved lineage-specific

Fuzzy patterns were just what resulted when chemical and biological engineer Ankur Gupta at the University of Colorado, Boulder, and his then research assistant Ben Alessio tried to simulate hexagonal patterns in a computer Turing model .  They were nothing like what nature produces. But the scientists found a solution in a concept called diffusiophoresis , in which small molecules push or pull bigger ones; it’s how small soap molecules yank big bits of dirt from your clothes in the washing machine.  When the researchers added diffusiophoresis to their models, the patterns looked a lot more like the boxfish’s scales, though they were still far from perfect. The researchers suspect that some small Turing morphogen is dragging the fish’s pigment cells into place, and that the fish uses other patterning methods, too. “Absolutely, there are other factors that might be at play,” says Gupta.

"Φsat-2, ESA’s groundbreaking cubesat designed to revolutionise Earth observation with artificial intelligence, has launched. "The cubesat embarked on its journey into space on 16 August at 20:56 CEST (11:56 local time) on board a SpaceX Falcon 9 rocket from the Vandenberg Space Force Base in California, US, integrated by Exolaunch as part of the Transporter-11 rideshare mission, which also included ESA’s Arctic Weather Satellite. "At 21:50 CEST, Φsat-2 deployed from the launch vehicle and at 23:47 CEST the Svalbard ground station in Norway received the important signal indicating that Φsat-2 is now safely in orbit . "Φsat-2 will push the boundaries of Earth observation, demonstrating how AI technologies can be used to advance how we observe Earth from space.  "The miniature satellite is equipped with a state-of-the-art multispectral camera and powerful AI computer that analyses and processes imagery while in orbit . This will prove critical for disaster respon

"First of all, it turns out that the equations that we use have approximate closed-form solutions that are bounded .  "And so we can replace the differential equation with a closed-form equation that behaves beautifully. And so that’s one advantage. "Also, because of the way we have structured the network, we can apply dynamical systems theory and control theory to analyzing the network.  "And finally, because these models are so much smaller, we can extract decision trees that will tell you how the network reaches its decisions. "We haven’t finished the work on liquid networks . In fact, we started working on this topic only a few years ago, and there’s so much more to be done.  "But it’s very, very exciting, and I’m very happy that we have access to analysis tools from a wide range of areas of math and of robotics to apply to these new models."

"The latest iteration of OpenAI’s powerful text generating language model, completes James Joyce’s Finnegans Wake (1939), first using the initial sentence of the original as a prompt, then working from the final words .  "Cunningly, the third version of the opening picks up the unstopped ending, endorsing the standard view of the Wake’s circularity.  "As I argue in Artefacts of Writing, the final words can also be read as opening onto the blank space remaining on the final printed page, leaving room for us, or GPT-3, to continue in our/its own way.  "As cunningly, the final version (8) of the ending takes us back to the beginning, mimicking version 3. In my view, version 7 is the most moving, given the way Finnegans Wake actually ends —with ALP contemplating death as an joyceanic release from a difficult life.  "That said, version 4 is also a pretty good description of what a bio-cultural intelligence might ideally think after reading the Wake (see What is

Silicon Valley is no stranger to cultural appropriation. In the tech industry, there are official job titles that use the words “guru,” “ninja,” “samurai,” and now, Sherpa .  While there’s a long history of “C++ ninjas” and “MySQL Rockstars,” “Sherpa” is a newer one. This borrowing of Eastern culture is nothing new for the tech industry, but in the last decade a growing number of companies have incorporated the term “Sherpa” into their names, or have even blatantly used it in their marketing. What is the reason for the rise of the Sherpa? In the West, the term “sherpa” is associated with the broader idea of a “guide.” That’s because historically, Sherpas have helped travelers navigate the treacherous mountain terrain of the Himalayas. Edmund Hillary, regarded as the first person to ascend Mt. Everest, was only able to make his trek because of the assistance of his Sherpa guide, Tenzing Norgay. The term “Sherpa” doesn’t literally mean “guide.” The Sherpas are an ethnic minority group l

Scientists at NASA's Cold Atom Lab (CAL) onboard the International Space Station (ISS) have announced that, for the first time, they have successfully made high-precision measurements using a quantum sensor based on ultra-cold atoms of the element Rubidium. This is a significant achievement with wide-ranging applications, as these sensors could surpass traditional ones in sensitivity and accuracy, enabling advancements in fields like GPS technology and telecommunications. Additionally, working versions of these sensors would offer new opportunities for scientific discoveries through the study of quantum phenomena , testing the limits of fundamental physics and maybe even pushing beyond theories such as general relativity and the Standard Model of particle physics. If so, that would undoubtedly lead to a revolution in space exploration as well. "Reaching this milestone was incredibly challenging, and our success was not always a given," Jason Williams, the Cold Atom Lab pr

"This week, X launched an AI-image generator, allowing paying subscribers of Elon Musk’s social platform to make their own art . So —naturally —some users appear to have immediately made images of  Donald Trump flying a plane toward the World Trade Center;  Mickey Mouse wielding an assault rifle, and  Another of him enjoying a cigarette and some beer on the beach; and so on.  "Some of the images that people have created using the tool are deeply unsettling; others are just strange, or even kind of funny. They depict wildly different scenarios and characters.  "But somehow they all kind of look alike, bearing unmistakable hallmarks of AI art that have cropped up in recent years thanks to products such as Midjourney and DALL-E. "Two years into the generative-AI boom, these programs’ creations seem more technically advanced —the Trump image looks better than, say, a similarly distasteful one of SpongeBob SquarePants that Microsoft’s Bing Image Creator generated last O

“Magic’s greatest asset has always been its commitment to create a new illustration for every new card,” he [Sam] said. He adds that if we sacrifice that commitment for A.I., “you’d get to a point pretty fast where it just disintegrates and becomes the ugliest definition of the word product.” So far, Magic’s parent company, Wizards of the Coast, has outwardly agreed with Sam, saying in an official statement in 2023 that Magic “has been built on the innovation, ingenuity, and hard work of talented people” and forbidding outside creatives from using A.I. in their work.  However, a number of recent incidents —from the accidental use of A.I. art in a Magic promotional image to a very intentional LinkedIn post for a “Principal AI Engineer,” one that Wizards had to clarify was for the company’s video game projects —have left many players unsure whether Wizards is potentially evolving their stance, or merely trying to find their footing in an ever-changing A.I. landscape .  Like most fans, Ma
