Only around 175 broadsides copies of the document are believed to exist. Breakthroughs, discoveries, and DIY tips sent six days a week. The Declaration of Independence is up for sale, but it will cost more than most of us can afford. Despite this, the edition offered by Goldin Auction originally printed and distributed so that colonists could read the Second Continental Congress' argument for separating from Great Britain in July 1776. The document is part of a collection of over 400 historic items scheduled for auction in May, and is set to coincide with the 250th anniversary of American independence .

Inside Story Why is the Doomsday Clock nearer to midnight than ever before? Atomic scientists raise alarm over more global conflict and new risks such as artificial intelligence. The Doomsday Clock has reached the closest ever point to midnight, according to the atomic scientists who run it. They say more wars, aggression from nuclear powers and weaker arms controls are to blame, along with climate change and risks posed by AI. So, should we be worried?

The world's first ultra-realistic robot artist Ai-Da Robot can create architectural designs using camera eyes and AI algorithms. Her Space Pod concept envisions modular housing.

Apple acquires Q.ai for a reported $2 billion Apple has acquired Israel-based startup Q.ai, a move that could provide a much-needed boost to the tech giant's capabilities in artificial intelligence. Although Apple has not disclosed terms of the deal, sources told that the arrangement is reportedly valued at nearly $2 billion. If that figure is accurate, the Q.ai acquisition marks Apple's second largest acquisition to date, followed by its purchase of Beats for $3 billion back in 2014. Johny Srouji, Apple's senior vice president of hardware technologies, said in a statement that Q.ai is a remarkable company that is pioneering new and creative ways to use imaging and machine learning. Apple hasn't shared any specifics about how it plans to leverage the startup, but its past work indicates the possibility of Apple moving deeper into AI-powered wearables.

As the world's largest companies pour hundreds of billions of dollars into large language models, San Francisco-based Logical Intelligence is trying something different in pursuit of AI that can mimic the human brain. If you ask Yann LeCun, Silicon Valley has a groupthink problem. Since leaving Meta in November, the researcher and AI luminary has taken aim at the orthodox view that large language models (LLMs) will get us to artificial general intelligence (AGI), the threshold where computers match or exceed human smarts. Everyone, he declared in a recent interview, has been "LLM-pilled." On January 21, San Francisco-based startup Logical Intelligence appointed LeCun to its board .

Immigration agencies have been flooding social media with bizarre, seemingly AI-generated content. We now know more about what might be making it. The US Department of Homeland Security is using AI video generators from Google and Adobe to make and edit content shared with the public, a new document reveals. It comes as immigration agencies have flooded social media with content to support President Trump's mass deportation agenda--some of which appears to be made with AI--and as workers in tech have put pressure on their employers to denounce the agencies' activities. The document, released on Wednesday, provides an inventory of which commercial AI tools DHS uses for tasks ranging from generating drafts of documents to managing cybersecurity. In a section about "editing images, videos or other public affairs materials using AI," it reveals for the first time that DHS is using Google's Veo 3 video generator and Adobe Firefly, estimating that the agency has between 100 and 1,000 licenses for the tools.

The number of planning applications for new homes in England is at its highest level for four years, new data shared with BBC Verify suggests. Applications for 335,000 homes outside London were lodged in 2025, up by 60% on 2024, according to Planning Portal, the service people use to request permission. But there are warnings that more needs to be done to meet Labour's target of building 1.5 million homes by 2029, as separate government data released on Thursday suggests there has been a decrease in house building. The Ministry of Housing, Communities and Local Government said it had overhauled the planning system and removed long-standing barriers that have held back housebuilding. The increase in planning applications for new homes in England follows controversial reforms introduced by Labour, which allow development on some lower-quality green belt land, known as grey belt .

As global air passenger traffic is forecast to hit 10.2 billion in 2026, a 3.9 percent year-on-year increase, investments have been pouring in to improve airport infrastructure and operational efficiency and use artificial intelligence to achieve it. Working with data released by Airport Council International, a irports are relying on the increasing use of AI to embrace the rise in demand. The use of AI-powered analytics to anticipate congestion at security, immigration and boarding points is also helping to prevent delays. Resources are being allocated to shift from reactive crowd management to predictive operations. AI-powered baggage optimisation tools and biometric processing - which would allow passengers to walk through immigration without the need to present a physical passport - are also gaining traction as airports seek to improve passenger experience while maintaining operational efficiency.

AI chat toy company Bondu left its web console almost entirely unprotected. Researchers who accessed it found nearly all the conversations children had with the company's stuffed animals. Earlier this month, Joseph Thacker's neighbor mentioned to him that she'd preordered a couple of stuffed dinosaur toys for her children. She'd chosen the toys, called Bondus, because they offered an AI chat feature that lets children talk to the toy like a kind of machine-learning-enabled imaginary friend. But she knew Thacker, a security researcher, had done work on AI risks for kids, and she was curious about his thoughts.

Climate change and pollution are making rare winter cyanobacteria blooms more common. Breakthroughs, discoveries, and DIY tips sent six days a week. In the Czech Republic, a frozen lake's emerald green ice is giving biologists an unprecedented opportunity to study a strange--and ominous--natural phenomenon. At the end of 2025, researchers at Czech Academy of Sciences traveled to Lake Lipno in South Bohemia to collect and examine samples from a rare cyanobacteria bloom in the dead of winter. Their findings could help better understand a problem that threatens both local marine life and nearby human populations.
