An anonymous reader quotes a report from Ars Technica: A team of researchers at the Italian Institute of Technology (IIT) in Milan recently created a fully rechargeable battery using nontoxic edible components. This is probably the world's first battery that is safe to ingest and entirely made of food-grade materials. "Given the level of safety of these batteries, they could be used in children's toys, where there is a high risk of ingestion," said Mario Caironi, a senior researcher at IIT. However, this isn't the only solution the edible battery could provide. Apart from serving as an alternative to conventional toxic toy batteries, the edible battery from IIT could also play a key role in making health care applications safer than ever. For instance, doctors have to be cautious regarding the use of miniature electronic devices (such as drug-delivery robots, biosensors, etc.) inside the human body, as they come equipped with batteries made of toxic substances. An edible battery could solve this problem. There are also more mundane applications, like replacing batteries in pet toys.

Ivan K. Ilic, first author of the study and a postdoctoral researcher at IIT, told Ars Technica, "Two main ways a battery damages human tissue when it's inside the body is by doing water electrolysis and by the toxicity of its materials. Water electrolysis is a phenomenon where electricity with a voltage higher than 1.2 V (virtually all commercial batteries) breaks water into oxygen and hydrogen (an explosive gas), and it is very dangerous if it occurs in the stomach. Our battery is way below this voltage, around 0.65 V, so water electrolysis cannot occur. On the other hand, we used only food materials, so nothing is toxic!" Before the battery is useful, however, the researchers will need to first enhance the battery's power capacity. Currently, the edible battery can supply 48 microamperes of current for a bit over 10 minutes. So it can easily meet the power demand of a miniature medical device or a small LED. "These batteries are no competition to ordinary batteries -- they will not power electric cars -- but they are meant to power edible electronics and maybe some other niche applications, so their main advantage is non-toxicity," said Ilic. Here's a list of what makes these edible batteries work, as mentioned by Ars:

- "Quercetin, a pigment found in almonds and capers, serves as the battery cathode, whereas riboflavin (vitamin B2) makes up the battery anode.
- The researchers used nori (edible seaweed that is used in the wrapping of sushi rolls) as the separator and a water-based solution (aqueous NaHSO4) as the electrolyte.
- Activated charcoal is employed to achieve high electrical conductivity in the battery.
The battery electrodes come covered in beeswax and connect to a gold foil (used to cover pastries) that laminates a supporting structure made of ethyl cellulose."

The research has been published in the journal Advanced Materials.

Spotify has removed tens of thousands of songs from artificial intelligence music start-up Boomy, ramping up policing of its platform amid complaints of fraud and clutter across streaming services. From a report: In recent months the music industry has been confronting the rise of AI-generated songs and, more broadly, the growing number of tracks inundating streaming platforms daily. Spotify, the largest audio streaming business, recently took down about 7 per cent of the tracks that had been uploaded by Boomy, the equivalent of "tens of thousands" of songs, according to a person familiar with the matter. Recording giant Universal Music had flagged to all the main streaming platforms that it saw suspicious streaming activity on Boomy tracks, according to another person close to the situation.

The Boomy songs were removed because of suspected "artificial streaming" -- online bots posing as human listeners to inflate the audience numbers for certain songs. AI has made this type of activity easier because it allows someone to instantly generate many music tracks, which can then be uploaded online and streamed. Boomy, which was launched two years ago, allows users to choose various styles or descriptors, such as "rap beats" or "rainy nights," to create a machine-generated track. Users can then release the music to streaming services, where they will generate royalty payments. California-based Boomy says its users have created more than 14mn songs.

Amazon CTO Werner Vogels, writes in a blog post: Software architectures are not like the architectures of bridges and houses. After a bridge is constructed, it is hard, if not impossible, to change the way it was built. Software is quite different, once we are running our software, we may get insights about our workloads that we did not have when it was designed. And, if we had realized this at the start, and we chose an evolvable architecture, we could change components without impacting the customer experience. My rule of thumb has been that with every order of magnitude of growth you should revisit your architecture, and determine whether it can still support the next order level of growth.

A great example can be found in two insightful blog posts written by Prime Video's engineering teams. The first describes how Thursday Night Football live streaming is built around a distributed workflow architecture. The second is a recent post that dives into the architecture of their stream monitoring tool, and how their experience and analysis drove them to implement it as a monolithic architecture. There is no one-size-fits-all. We always urge our engineers to find the best solution, and no particular architectural style is mandated. If you hire the best engineers, you should trust them to make the best decisions.

I always urge builders to consider the evolution of their systems over time and make sure the foundation is such that you can change and expand them with the minimum number of dependencies. Event-driven architectures (EDA) and microservices are a good match for that. However, if there are a set of services that always contribute to the response, have the exact same scaling and performance requirements, same security vectors, and most importantly, are managed by a single team, it is a worthwhile effort to see if combining them simplifies your architecture.

Evolvable architectures are something that we've taken to heart at Amazon from the very start. Re-evaluating and re-architecting our systems to meet the ever-increasing demands of our customers. You can go all the way back to 1998, when a group of senior engineers penned the Distributed Computing Manifesto, which put the wheels in motion to move Amazon from a monolith to a service-oriented architecture. In the decades since, things have continued to evolve, as we moved to microservices, then microservices on shared infrastructure, and as I spoke about at re:Invent, EDA.

Textbooks giant Pearson is currently taking legal action over the use of its intellectual property to train AI models, chief executive Andy Bird revealed today as the firm laid out its plans for its own artificial intelligence-powered products. From a report: The firm laid out its plans on how it would use AI a week after its share price tumbled by 15% as American rival Chegg said its own business had been hurt by the rise of ChatGPT. Those plans would include AI-powered summaries of Pearson educational videos, to be rolled out this month for Pearson+ members, as well as AI-generated multiple choice questions for areas where a student might need more help. Bird said Pearson had an advantage as its AI products would use Pearson content for training, which he said would make it more reliable. However, he also added that the business was also monitoring the situation regarding other businesses using Pearson content to train its AI. He said Pearson had already sent out a cease-and-desist letter, though did not say who it was addressed to.

Anthropic, an artificial intelligence startup backed by Google owner Alphabet, on Tuesday disclosed the set of written moral values that it used to train and make safe Claude, its rival to the technology behind OpenAI's ChatGPT. From a report: The moral values guidelines, which Anthropic calls Claude's constitution, draw from several sources, including the United Nations Declaration on Human Rights and even Apple's data privacy rules. Anthropic was founded by former executives from Microsoft-backed OpenAI to focus on creating safe AI systems that will not, for example, tell users how to build a weapon or use racially biased language. Co-founder Dario Amodei was one of several AI executives who met with Biden last week to discuss potential dangers of AI.

Most AI chatbot systems rely on getting feedback from real humans during their training to decide what responses might be harmful or offensive. But those systems have a hard time anticipating everything people might ask, so they tend to avoid some potentially contentious topics like politics and race altogether, making them less useful. Anthropic takes a different approach, giving its Open AI competitor Claude a set of written moral values to read and learn from as it makes decisions on how to respond to questions. Those values include "choose the response that most discourages and opposes torture, slavery, cruelty, and inhuman or degrading treatment," Anthropic said in a blog post on Tuesday.

Meta has announced a new open-source AI model that links together multiple streams of data, including text, audio, visual data, temperature, and movement readings. From a report: The model is only a research project at this point, with no immediate consumer or practical applications, but it points to a future of generative AI systems that can create immersive, multisensory experiences and shows that Meta continues to share AI research at a time when rivals like OpenAI and Google have become increasingly secretive. The core concept of the research is linking together multiple types of data into a single multidimensional index (or "embedding space," to use AI parlance). This idea may seem a little abstract, but it's this same concept that underpins the recent boom in generative AI.

Apple is bringing Final Cut Pro and Logic Pro to the iPad. Both apps will be available for $4.99 per month or $49 per year on iPad starting on May 23rd. For comparison, buying Logic Pro on a Mac costs $199.99, and buying Final Cut Pro normally costs $299.99. From a report: The video and music editing apps will come with enhancements specifically for iPads. Final Cut Pro, for example, will come with a new jog wheel that's supposed to make the editing process "easier than ever," allowing you to navigate the magnetic timeline, move clips, and perform edits using just your finger and multi-touch gestures. There's also a new feature called Live Drawing that lets you use your Apple Pencil to draw and write directly on top of video content. If you have an iPad Pro with an M2 chip, you can use the Apple Pencil's hover feature to skim and preview footage without even touching the screen.

IBM on Tuesday launched watsonx, a new artificial intelligence and data platform to help companies integrate AI in their business. From a report: The new AI platform launch comes over a decade after IBM's software called Watson got attention for winning the game show Jeopardy. IBM at the time said Watson could "learn" and process human language. But Watson's high cost at the time made it a challenge for companies to use, according to Reuters reporting. Fast forward a decade, chatbot ChatGPT's overnight success is making AI adoption at companies a focus, and IBM is looking to grab new business. This time, the lower cost of implementing the large language AI models means the chances of success are high, IBM CEO Arvind Krishna told Reuters ahead of the company's annual Think conference.

"When something becomes 100 times cheaper, it really sets up an attraction that's very, very different," said Krishna. "The first barrier to create the model is high, but once you've done that, to adapt that model for a hundred or a thousand different tasks is very easy and can be done by a non-expert." Krishna said AI could reduce certain back office jobs at IBM in the coming years. "That doesn't mean the total employment decreases," he said about some media reports talking about IBM pausing hiring for thousands of jobs that AI could replace. "That gives the ability to plow a lot more investment into value-creating activities...We hired more people than were let go because we're hiring into areas where there is a lot more demand from our clients."

A vulnerability in the "Advanced Custom Fields" plugin for WordPress is putting more than two million users at risk of cyberattacks, warns Patchstack researcher Rafie Muhammad. The Register reports: A warning from Patchstack about the flaw claimed there are more than two million active installs of the Advanced Custom Fields and Advanced Custom Fields Pro versions of the plugins, which are used to give site operators greater control of their content and data, such as edit screens and custom field data. Patchstack researcher Rafie Muhammad uncovered the vulnerability on February 5, and reported it to Advanced Custom Fields' vendor Delicious Brains, which took over the software last year from developer Elliot Condon. On May 5, a month after a patched version of the plugins was released by Delicious Brains, Patchstack published details of the flaw. It's recommended users update their plugin to at least version 6.1.6.

The flaw, tracked as CVE-2023-30777 and with a CVSS score of 6.1 out of 10 in severity, leaves sites vulnerable to reflected XSS attacks, which involve miscreants injecting malicious code into webpages. The code is then "reflected" back and executed within the browser of a visitor. Essentially, it allows someone to run JavaScript within another person's view of a page, allowing the attacker to do things like steal information from the page, perform actions as the user, and so on. That's a big problem if the visitor is a logged-in administrative user, as their account could be hijacked to take over the website.

"This vulnerability allows any unauthenticated user [to steal] sensitive information to, in this case, privilege escalation on the WordPress site by tricking the privileged user to visit the crafted URL path," Patchstack wrote in its report. The outfit added that "this vulnerability could be triggered on a default installation or configuration of Advanced Custom Fields plugin. The XSS also could only be triggered from logged-in users that have access to the Advanced Custom Fields plugin."

According to the Wall Street Journal (paywalled), the New York Times is getting around $100 million from Google over the next three years as part of a deal that allows Google to feature Times content on some of its platforms. Reuters reports: The deal includes the Times' participation in Google News Showcase, a product that pays publishers to feature their content on Google News and some other Google platforms, according to the report, which cited people familiar with the matter. The Times in February announced an expansion of its agreement with Google that included content distribution and subscriptions.

At its annual Google I/O developers conference on Wednesday, Google is planning to announce a number of generative AI updates, including launching a general-use large language model (LLM) called PaLM 2. CNBC reports: According to internal documents about Google I/O viewed by CNBC, the company will unveil PaLM 2, its most recent and advanced LLM. PaLM 2 includes more than 100 languages and has been operating under the internal codename "Unified Language Model." It's also performed a broad range of coding and math tests as well as creative writing tests and analysis. At the event, Google will make announcements on the theme of how AI is "helping people reach their full potential," including "generative experiences" to Bard and Search, the documents show. Pichai will be speaking to a live crowd of developers as he pitches his company's AI advancements.

Google first announced the PaLM language model in April of 2022. In March of this year, the company launched an API for PaLM alongside a number of AI enterprise tools it says will help businesses "generate text, images, code, videos, audio, and more from simple natural language prompts." Last month, Google said its medical LLM called "Med-PaLM 2" can answer medical exam questions at an "expert doctor level" and is accurate 85% of the time.

Facebook says it is not dead. Facebook also wants you to know that it is not just for "old people," as young people have been saying for years. From a report: Now, with the biggest thorn in its side -- TikTok -- facing heightened government scrutiny amid growing tensions between the U.S. and China, Facebook could, perhaps, position itself as a viable, domestic-bred alternative. There's just one problem: young adults like Devin Walsh (anecdote in the story) have moved on. [...] Today, 3 billion people check it each month. That's more than a third of the world's population. And 2 billion log in every day. Yet it still finds itself in a battle for relevancy, and its future, after two decades of existence. For younger generations -- those who signed up in middle school, or those who are now in middle school, it's decidedly not the place to be. Without this trend-setting demographic, Facebook, still the main source of revenue for parent company Meta, risks fading into the background -- utilitarian but boring, like email.

Windows 11's Settings panel has been seen with a number of adverts in test builds of the OS, in what's becoming a sadly familiar theme for preview builds of late. From a report: As spotted by German tech site Deskmodder, this was flagged up by a respected source for Microsoft leaks, Albacore, on Twitter. Albacore shared some screenshots of the new home page for the Settings app, as uncovered by digging into a Windows 11 preview from the Canary channel (the earliest test builds). The first screen grab (on the left in the above tweet) shows an ad for Microsoft 365 at the top of the panel, telling users what they get with the service and that they can try it for free (for a trial period). Under that, there's a prompt to 'finish setting up your account,' which refers to completing the setup of your Microsoft Account. The other screenshots also have prompts relating to the Microsoft Account, this time urging users to sign into the account, one of which is shown on the Settings home page and another in the Accounts section. In the latter, users are told to 'Sign in to get the most out of Windows.'

Singapore's government is taking the first steps toward codifying a new internet safety law that would grant it wide-ranging powers over content, access and communication online. From a report: The Online Criminal Harms Bill, introduced for a first reading in parliament on Monday, is aimed at cracking down on illicit activities like scams, misinformation, cybercrime drug trafficking and the spread of exploitative images. It is part of a wider "suite of legislation" to protect Singaporeans online, the Ministry of Home Affairs said in a statement. The bill is likely to pass into law without strong opposition, as most proposed legislation does in the city-state's parliament. It would grant the government broad powers to restrict content online: from blocking the communication of certain material or web addresses to removing apps from mobile stores or restricting accounts on social networks. It further advocates a proactive approach to preventing malicious cyber activity, allowing those powers to be used on the suspicion that a given website or account may be used in such acts. The bill also includes a provision for service providers to appeal the government's directives.

Truecaller will soon start making its caller identification service available over WhatsApp and other messaging apps to help users spot potential spam calls over the internet, the company told Reuters on Monday. From a report: The feature, currently in beta phase, will be rolled out globally later in May, Truecaller Chief Executive Alan Mamedi said. Telemarketing and scamming calls have been on the rise in countries like India, where users gets about 17 spam calls per month on average, according to a 2021 report by Truecaller. "Over the last two weeks, we have seen a spike in user reports from India about spam calls over WhatsApp," Mamedi said, noting that telemarketers switching to internet calling was fairly new to the market.

Amid broader venture-capital doldrums, it is boom times for startups touting generative artificial intelligence tech. From a report: Before their startup had customers, a business plan or even a formal name, former Google AI researchers Niki Parmar and Ashish Vaswani were fielding interest from investors eager to back the next big thing in artificial intelligence. At Google, Ms. Parmar and Mr. Vaswani were among the co-authors of a seminal 2017 paper that helped pave the way for the boom in so-called generative AI. Earlier this year, only weeks after striking out on their own, they raised funds that valued their fledgling company -- now called Essential AI -- at around $50 million, people familiar with the company said. While most of Silicon Valley's venture-capital ecosystem remains in the doldrums, investors this year have been pouring funds into companies like Essential specializing in generative AI systems that can create humanlike conversation, imagery and computer code. Many of the companies getting backing are new and unproven.

Analysts at research firm PitchBook predict that venture investment in generative AI companies will easily be several times last year's level of $4.5 billion. That is driven in part by Microsoft's $10 billion investment in January into OpenAI, the startup behind the wildly popular ChatGPT bot. In comparison, such investment totaled $408 million in 2018, the year OpenAI released the initial version of the language model powering ChatGPT. Entrepreneurs and their backers are hoping generative AI will change business activities from movie production to customer service to grocery delivery. PitchBook estimates the market for such AI applications in enterprise technology alone will rise to $98 billion in 2026 from nearly $43 billion this year. As with the recently ended bull run of broader startup investing, though, investors often are jumping into AI startups even when it isn't clear how they will make a profit -- especially since the computational power required to train AI services can sometimes amount to tens of millions of dollars a year or more. The sudden influx of capital is also encouraging many AI researchers, some without management or operations experience, to start their own companies, adding to competition.

An anonymous reader shares a report: In the age of large language models (LLMs) and ChatGPT, AI is poised to make a weird internet even weirder -- turning the content-driven social media apps, news sites and media platforms of today into future uncanny valleys that blur the line between man and machine. As advances in AI make it more difficult to discern bots from humans, Sam Altman, the co-founder of Open AI -- the company behind ChatGPT -- thinks blockchains can help. Altman's crypto project, Worldcoin, rose to prominence last year with a controversial, Silicon Valley vision for a universal basic income (UBI): a crypto token that can be distributed in equal quantity to everyone in the world.

Worldcoin is back again this week with a new launch -- this one poised to be its biggest yet. World App, Worldcoin's crypto wallet, built on the Ethereum sidechain Polygon, is the first product from the elusive identity upstart that anyone, anywhere will be able to download. The new app is one part minimalist crypto wallet, and one part passport for the AI era. It's Worldcoin's biggest swing yet to redefine itself in the eyes of consumers.

Slack sees the future: Imagine if every time you hop into a channel, you'll be able to get up to speed on unread Slack messages in one click — whether you're jumping in midway through a project or catching up from being out of the office. In the future, with generative AI built seamlessly into the user experience, conversation summaries will be there when you need them, the moment you start scrolling through a channel.

With AI assistance built natively into Slack's message composer and canvas, a new surface for curating information, Slack GPT could also help you tweak your drafts until the words are just right. In a few clicks, you'll be able to distill content, adjust the tone, and more, right from where you're already writing.
In fact, Slack "previewed generative AI tools on Thursday," reports the Register, "currently under development and bundled under the banner Slack GPT." Customers will be able to use large language models like Anthropic's Claude as well as OpenAI's GPT to instruct the chatbots to perform other tasks, like search or answering questions.

Slack is also working on Workflow Builder — a no-code automation tool that will enable users to add generative prompts to automatically perform tasks for them, like setting up alerts or writing and sharing documents... Other tools, like its forthcoming Einstein GPT app, are aimed at supporting existing Salesforce services in its CRM software. Users of Salesforce Customer 360 data and Data Cloud — like customer service agents, sales reps, or marketers — can access language models to generate leads, write emails, schedule meetings, or draft plans. Einstein GPT will also be able to handle code, so developers can ask chatbots to write short programs or fix bugs.

It's not clear when Slack GPT or Einstein GPT will be generally available. Integration with Anthropic's Claude, however, is available now, whilst integration with ChatGPT is currently in beta. Workflow Builder is scheduled to be released in summer this year.
From Slack's announcement: Say you have a workflow that alerts you when a new lead comes in from Sales Cloud, ensuring sales reps can quickly respond. Imagine if ChatGPT could take your workflow a few steps further, using CRM data from a sales lead to draft a personalized prospecting email for you? Put it in a document, share it in a channel, and every sales rep now has a head start when they follow up on the lead.

A Norwegian company named ENRX "wants to inductively charge electric vehicles with 200 kW while driving on a section of highway in Florida," according to the "electric mobility industry" news site electrive.com.

"A one-mile section of a four-lane highway near Orlando is to be electrified." ENRX has teamed up with the Central Florida Expressway Authority and the Aspire Engineering Research Center for an initiative to build a one-mile (1.6-kilometre) section on a four-lane highway near Orlando that will inductively charge the batteries of moving electric vehicles at 200 kW.

The principle is clear: the electric vehicle batteries are fitted with a special receiver pad and charged as they drive over the coils embedded in the road. In the process, the energy is transferred from these coils to the receiver pad mounted on the vehicle floor, which according to ENRX should provide "a safe, wireless power supply" even at motorway speeds. Advantages of the 'Next Generation Electric Roadway system' mentioned include interoperability, different output power levels for different vehicle and battery types, or user-defined distance between the ground and the vehicle. In addition, the system (on the infrastructure side) is supposed to be maintenance-free after installation...

"When you can charge while driving, range anxiety and frequent charging stops will be a thing of the past," says ENRX CEO Bjørn Eldar Petersen... "Dynamic charging can reduce the need for large battery capacities, allowing cars to be equipped with lighter and more affordable battery packs."
Thanks to long-time Slashdot reader aduxorth for sharing the news.

Slashdot reader indominabledemon shared this article from TechSpot: Games today use highly-detailed textures that can quickly fill the frame buffer on many graphics cards, leading to stuttering and game crashes in recent AAA titles for many gamers... [T]he most promising development in this direction so far comes from Nvidia — neural texture compression could reduce system requirements for future AAA titles, at least when it comes to VRAM and storage.... In a research paper published this week, the company details a new algorithm for texture compression that is supposedly better than both traditional block compression (BC) methods as well as other advanced compression techniques such as AVIF and JPEG-XL.

The new algorithm is simply called neural texture compression (NTC), and as the name suggests it uses a neural network designed specifically for material textures. To make this fast enough for practical use, Nvidia researchers built several small neural networks optimized for each material... [T]extures compressed with NTC preserve a lot more detail while also being significantly smaller than even these same textures compressed with BC techniques to a quarter of the original resolution... Researchers explain the idea behind their approach is to compress all these maps along with their mipmap chain into a single file, and then have them be decompressed in real time with the same random access as traditional block texture compression...

However, NTC does have some limitations that may limit its appeal. First, as with any lossy compression, it can introduce visual degradation at low bitrates. Researchers observed mild blurring, the removal of fine details, color banding, color shifts, and features leaking between texture channels. Furthermore, game artists won't be able to optimize textures in all the same ways they do today, for instance, by lowering the resolution of certain texture maps for less important objects or NPCs. Nvidia says all maps need to be the same size before compression, which is bound to complicate workflows. This sounds even worse when you consider that the benefits of NTC don't apply at larger camera distances.

Perhaps the biggest disadvantages of NTC have to do with texture filtering. As we've seen with technologies like DLSS, there is potential for image flickering and other visual artifacts when using textures compressed through NTC. And while games can utilize anisotropic filtering to improve the appearance of textures in the distance at a minimal performance cost, the same isn't possible with Nvidia's NTC at this point.
