My wife and I like to travel to other countries, but we always face a familiar obstacle -- how to learn the language well enough to converse with people. We've tried taking language lessons, yet we invariably run into situations where we can't find the right words to express ourselves. Now, Google has launched a trio of translation tools that could help overcome this obstacle. Also: Want a quick daily podcast based on your interests? Try Google's latest AI experiment Launched on Tuesday as Google Labs experiments, the "Little Language Lessons" are designed to assist you in specific situations, especially when you're traveling in a foreign country.

Researchers have discovered that lucid dreaming is more than just a vivid sleep state, it's actually a whole other state of consciousness. Lucid dreaming occurs when a person becomes aware they are dreaming, often gaining the ability to control the dream's events. For instance, they might fly, walk through walls, or confront fears, taking advantage of the limitless possibilities. Previously, scientists believed lucid dreams were simply more vivid or intense versions of the typical dreams that occur during REM (rapid eye movement) sleep, which is a normal phase of the sleep cycle characterized by increased brain activity. But this new study shows that brain activity patterns during a lucid dream are entirely different from those that occur during regular dreams and wakefulness.

A young man with no government experience who has yet to even complete his undergraduate degree is working for Elon Musk's so-called Department of Government Efficiency (DOGE) at the Department of Housing and Urban Development (HUD) and has been tasked with using artificial intelligence to rewrite the agency's rules and regulations. Christopher Sweet was introduced to HUD employees as being originally from San Francisco and most recently a third-year at the University of Chicago, where he was studying economics and data science, in an email sent to staffers earlier this month. "I'd like to share with you that Chris Sweet has joined the HUD DOGE team with the title of special assistant, although a better title might be'Al computer programming quant analyst,'" Scott Langmack, a DOGE staffer and chief operating officer of an AI real estate company, wrote in an email widely shared within the agency and reviewed by WIRED. "With family roots from Brazil, Chris speaks Portuguese fluently. Please join me in welcoming Chris to HUD!" Sweet's primary role appears to be leading an effort to leverage artificial intelligence to review HUD's regulations, compare them to the laws on which they are based, and identify areas where rules can be relaxed or removed altogether.

California continues to invest in its tech prowess, as Governor Gavin Newsom announces new generative AI initiatives that sick the technology onto some of the state's biggest man-power burdens. Part of the leader's executive order on AI, which directed state agencies to implement the new technology in the name of efficiency, three new agreements will see state investments in some of the industry's most popular generative AI technologies, meant to reduce highway congestion, improve roadway safety, and enhance customer service in state call centers. "GenAI is here, and it's growing in importance every day. We know that state government can be more efficient, and as the birthplace of tech it is only natural that California leads in this space," said Newsom. "In the Golden State, we know that efficiency means more than cutting services to save a buck, but instead building and refining our state government to better serve all Californians." Specifically, the California Department of Transportation (Caltrans) will use Microsoft's Azure Open AI to process and analyze traffic data in order to "reduce traffic congestion, enhance incident response, and improve transit reliability."

AI-generated computer code is rife with references to non-existent third-party libraries, creating a golden opportunity for supply-chain attacks that poison legitimate programs with malicious packages that can steal data, plant backdoors, and carry out other nefarious actions, newly published research shows. The study, which used 16 of the most widely used large language models to generate 576,000 code samples, found that 440,000 of the package dependencies they contained were "hallucinated," meaning they were non-existent. A dependency is an essential code component that a separate piece of code requires to work properly. Dependencies save developers the hassle of rewriting code and are an essential part of the modern software supply chain. These non-existent dependencies represent a threat to the software supply chain by exacerbating so-called dependency confusion attacks.

In little more than 1,600 words voicing his scepticism over net zero policies, Tony Blair this week propelled himself and his increasingly powerful institute back into the national debate. In the past eight years, the former prime minister has built a global empire employing more than 900 people across more than 40 countries, providing policy advice to monarchs, presidents and prime ministers. But while Blair's thinktank has brought him influence in his post-Downing Street career, it has also renewed scrutiny on his political views and how they are shaped by his commercial relationships. The Labour MP James Frith said on Wednesday: "I give congratulations to the marketing department at the Tony Blair Institute (TBI), who have managed to time it brilliantly to get maximum coverage." Patrick Galey, the head of fossil fuel investigations at the nongovernmental organisation Global Witness, said: "Blair's well-documented links to petrostates and oil and gas companies ought to alone be enough to disqualify this man as an independent and reliable arbiter of what's possible or commonsense in the energy transition."

Artists including Paul McCartney and Tom Stoppard have thrown their weight behind a campaign against the changes in a series of high-level interventions. The government's commitments will be made in amendments to the data bill, which has become a vehicle for campaigners against the changes and is due to return to the Commons on Wednesday next week. The move has already been dismissed by critics. Ed Newton-Rex, a the British composer and prominent campaigner against the government proposals, said there was a "ton of evidence" showing the mooted changes were "terrible for creators". He added: "We don't need an impact assessment to tell us this."

AI has transformed everyday tasks such as writing, coding -- even shopping. Now, Visa is introducing an initiative to prepare its payment network for a new era of agentic AI shopping experiences. On Wednesday, the company unveiled Visa Intelligent Commerce at the Visa Global Product Drop. According to the release, this initiative opens Visa's payment network to developers and engineers who are building agentic AI shopping experiences that find and buy products for users. Moreover, Visa Intelligent Commerce is a commercial partner program for AI platforms that includes a suite of integrated APIs developers can use to deploy Visa's AI commerce capabilities.

Meta is set to report its first quarter earnings on Wednesday after the bell, and investors will be looking for news on whether the company met its quarterly revenue goals of somewhere between 39.5bn and 41.8bn. Wall Street is projecting the company will post 41.36bn in revenue on 5.21 in earnings per share. While Meta has repeatedly beaten Wall Street expectations in the past few quarters, analysts were disappointed by the first quarter revenue outlook Meta chief executive Mark Zuckerberg shared at the end of 2024. The company is also planning on spending up to 65bn on AI infrastructure by the end of 2025. Uncertainty over Donald Trump's sweeping tariffs may yet roil ad markets, clouding the company's financial outlook for near future quarters.

Over a decade ago, I sat in my living room with a bunch of nerds, tears pricking my eyes, as I saw the Curiosity rover's first blurry selfie taken on Mars. The NASA livestream had just confirmed the wheeled robot was alive and well and ready to start doing science! We cheered and hugged and imagined a future where our solar system would be full of robotic explorers, gathering all the data we would need to safely send humans in their wake.
