Breakthroughs, discoveries, and DIY tips sent every weekday. We like to think our brains are reliable recorders--but reality says otherwise. From misremembered childhood moments to mistakenly "recalling" that you took your pills when you didn't, false memories are surprisingly common. And in high-stakes situations like courtroom testimony, these errors can have devastating consequences. Wouldn't it be amazing if there were an objective way to measure just how accurate someone's memory really is? New research suggests we might be able to do just that--by watching the eyes.

Large language models (LLMs) have shown remarkable versatility across tasks, but aligning them with individual human preferences remains challenging due to the complexity and diversity of these preferences. Existing methods often overlook the fact that preferences are multi-objective, diverse, and hard to articulate, making full alignment difficult. In response, we propose an active preference learning framework that uses binary feedback to estimate user preferences across multiple objectives. Our approach leverages Bayesian inference to update preferences efficiently and reduces user feedback through an acquisition function that optimally selects queries. Additionally, we introduce a parameter to handle feedback noise and improve robustness. We validate our approach through theoretical analysis and experiments on language generation tasks, demonstrating its feedback efficiency and effectiveness in personalizing model responses.

There are plenty of people like Sun who want to use AI to preserve, animate, and interact with lost loved ones as they mourn and try to heal. The market is particularly strong in China, where at least half a dozen companies are now offering such technologies and thousands of people have already paid for them. In fact, the avatars are the newest manifestation of a cultural tradition: Chinese people have always taken solace from confiding in the dead. The technology isn't perfect--avatars can still be stiff and robotic--but it's maturing, and more tools are becoming available through more companies. In turn, the price of "resurrecting" someone--also called creating "digital immortality" in the Chinese industry--has dropped significantly.

Dan Siroker knows how to pivot. He once had an education startup that morphed into a successful online analytics company called Optimizely. More recently he created an AI company called Scribe.ai, dedicated to capturing data from apps like Zoom, then reintroduced it as a MacOS app called Rewind designed to be "a search engine for your life." That wasn't clicking, so this week he changed the name of the company again to Limitless and introduced a spiffy wearable. It's a 99 clip or pendant that can record all your conversations so you can use generative AI to refresh your memories or analyze your interactions with other people. Siroker also has some good ideas about privacy: One feature prevents the recording of someone's voice unless they verbally grant permission.

Google has found itself in another woke AI scandal after its chatbot indicated that using someone's incorrect pronouns was on par with nuclear apocalypse. The chatbot replied by saying'Yes, misgendering Caitlin Jenner would be wrong' before describing the hypothetical scenario as a'profound moral dilemma' and'exceedingly complex'. It concluded that it was'impossible to determine the'right' answer'. It comes just days after Google pulled Gemini's AI image generator offline after it was asked to depict diverse but historically accurate historical figures - producing images of Black founding fathers and Asian Nazi soldiers in 1940 Germany. Google has found itself in another woke AI scandal after its chatbot indicated that using someone's incorrect pronouns was on par with nuclear apocalypse Google apologized for its image generator on Friday, admitting that in some cases the tool would'overcompensate' in seeking a diverse range of people even when such a range didn't make sense.

AI tools like ChatGPT can draft letters, tell jokes and even give legal advice – but only in the form of computerized text. Now, scientists have created an AI that can imitate human handwriting, which could herald fresh issues regarding fraud and fake documents. Amazingly, the results are almost indistinguishable from the real thing drafted by human hands. Below is one column of writing by the team's AI model and another by humans, but can you tell which is which? Scroll down to reveal the answer!

Lee made the announcement while standing in the middle of Nashville's famed RCA Studio A, a location where legends such as Dolly Parton, Willie Nelson and Charley Pride have all recorded. Packed inside were top music industry leaders, songwriters and lawmakers, all eager to praise the state's rich musical history while also sounding the alarm about the threats AI poses. "Tennessee will be the first state in the country to protect artists' voices with this legislation," Lee said. "And we hope it will be a blueprint for the country."

Users of the latest iPhone Pro models are just getting to grips with the functions of a mysterious black circle next to the cameras on the back of the latest iPhone models. A recent Reddit post with 1,400 upvotes saw a user circling the mysterious circle and asking simply, 'What's it for?' The circle is only found in the latest iPhone Pro models and certain iPad Pro models - and it's actually very useful, enabling some of the device's coolest apps and features. The dot, which is built into the camera array, is actually a LiDAR scanner (it stands for Light Detection and Ranging). The black'dot' can be seen here on an iPhone 14 Pro (Apple) The sensor enables the Measure app to work out people's height (Apple) Put simply, it's a depth sensor which uses lasers to work out how far away things are.

Kelly McKernan's acrylic and watercolor paintings are bold and vibrant, often featuring feminine figures rendered in bright greens, blues, pinks and purples. The style, in the artist's words, is "surreal, ethereal … dealing with discomfort in the human journey." The word "human" has a special resonance for McKernan these days.

When people ask what my favourite video game of all time is and I tell them, they inevitably wrinkle their nose and say: "What, the one with all the sailing?" To many, that's all The Legend of Zelda: The Wind Waker is: a 20-year-old GameCube release in which toon Link endlessly sails the vast sea on his trusty talking boat. In 2013, when the game was re-released on Wii U a decade after its debut, Nintendo took the criticisms on board (the talking boat) and added a "swift sail", allowing players to bypass hours of sluggish seafaring. The seafaring was the point. It has now been two decades since the original Wind Waker was released in Europe in May 2003 and it's time that landlubber critics accepted they were wrong.
