  Artificial intelligence chipmaker Nvidia's quarterly results surpassed Wall Street's expectations once again , fueled by massive demand for its high-end AI chips. The company said Wednesday it earned $58.32 billion, or $2.39 per share, in the February-April period, up from $18.78 billion, or 76 cents per share, in the same period a year earlier. Excluding one-time items, Nvidia earned $1.76 per share. Revenue jumped 85% to $81.62 billion from $44.01 billion. Analysts, on average, were expecting earnings of $1.75 per share and revenue of $78.91 billion, according to a poll by FactSet. Nvidia's results have exceeded the analyst projections that shape investors’ perceptions since Nvidia’s high-end chips emerged as AI’s best building blocks three years ago. “The buildout of AI factories — the largest infrastructure expansion in human history — is accelerating at extraordinary speed,” said CEO Jensen Huang in a statement. Along with higher profit and revenue, however, Nvidia...

  NEW YORK (AP) — Elon Musk announced plans Wednesday for one of the biggest stock sales ever by taking public a space company that is currently losing billions of dollars a year. A filing shows that his SpaceX lost $2.6 billion from operations last year on $18.7 billion in revenue, and the losses kept piling up at the start of this year, too. The prospectus did not put a dollar figure on the amount Musk hopes to raise, but various reports have put it at $75 billion or so. An offering of that size would easily surpass the current title holder, Saudi Aramco, the oil giant that went public seven years ago and raised $26 billion. SpaceX, formally known as Space Exploration Technologies Corp., has said the money will help finance projects to put people on the moon and Mars in its quest to make humans an intergalactic species as they face existential threats that could wipe out civilization. “We do not want humans to have the same fate as dinosaurs,” the filing states. The prospectus re...

  A BBC investigation revealed a simple way AI chatbots are being made to spit out misinformation to the public. Google and other AI companies are now trying to fix the problem. I did something stupid back in February. I heard there was an easy way to poison AI chatbots and make them spread lies on your behalf. After some digging, I learned unscrupulous companies are abusing the problem on a massive scale. So I decided to try it myself. We uncovered examples where ChatGPT, Gemini and the AI Overviews at the top of Google Search were being manipulated to dole out biased answers on topics as serious as your health and personal finances. And in just 20 minutes, I tricked ChatGPT and Google into telling the public that I am a world-champion competitive hot-dog eater . The joke was dumb. The problem is serious. But the gimmick worked. Our investigation and the work of researchers who've been monitoring this issue sparked widespread criticism. Now Google has updated its policies to addr...

  The University of Kent will be taking robots to the pub on Wednesday for a research project into human socialisation. School of Computing researchers are letting two robots meet the public at The Foundry in Canterbury as part of the international Pint of Science Festival. Dr Giovanni Masala, senior lecturer in computer science, explains: "The aim of the festival is to make the science understandable for all. Robots have had bad advertising in the movies, so we will try to explain their benefit." The research team says it hopes to bring new opportunities to develop robots which can support dementia care, learning, and assisted independent living at home. The robots, which usually reside within the Cognitive Robotics and Autonomous Systems Lab on the Canterbury campus, are designed to help older adults with daily tasks, memory, and companionship, all using everyday language. Buddy is a wheeled companion robot with a large, expressive facial screen to mimic human emotions for ...

  Crypto companies spent years monetizing volatility, but now, they’re trying to survive without it. First-quarter earnings underscored that crypto’s era of easy moonshots and hype-driven returns is fading. As lower bitcoin  and ether  prices drained speculative demand – and investors pulled back from risk assets broadly amid macro uncertainty – trading activity across exchanges cooled and retail participation faded. The slowdown showed up in public companies’ quarterly updates, with exchanges, brokers and crypto financial firms reporting weaker transaction and staking revenue and softer client activity. It’s nothing new to Coinbase  and Robinhood , for whom trading was once the lifeblood of their platforms. Both have been working for years on diversifying revenue by expanding their suite of financial services. But even non-trading businesses still operate in an industry shaped by crypto’s boom-and-bust cycles. And first-quarter earnings – particularly from the batch...
