A startup hopes to challenge Nvidia, AMD, and Intel with a chip that wrangles probabilities rather than ones and zeros. Extropic claims its exotic new chip, called XTR-0, could be thousands of times more energy efficient than existing chips when scaled up. Extropic, a startup developing an exotic new kind of computer chip that handles probabilistic bits, has produced its first working hardware along with proof that more advanced systems will tackle useful tasks in artificial intelligence and scientific research. The startup's chips work in a fundamentally different way to chips from Nvidia, AMD, and others, and promise to be thousands of times more energy efficient when scaled up. With AI companies pouring billions of dollars into building datacenters, a completely new approach could offer a far less costly alternative to vast arrays of conventional chips.

We'll let you decide if that justifies its sky-high price tag. "Set it and forget it" is something of a moving target in the world of robotic pool cleaners. While a few models have exceptional battery life--a bit more than six hours being about the best I've seen--many die after just a couple of hours in the water, requiring immediate retrieval and recharging.

Is the US eyeing its next Latin American target? Why is Trump tearing down parts of the White House? Nvidia has become the first company to reach $5 trillion in market value amid a global artificial intelligence arms race. The chipmaker surge on Wednesday came only three months after the company topped the $4 trillion mark . Since the launch of ChatGPT in 2022, Nvidia's shares have climbed 12-fold as the AI frenzy propelled the S&P 500 to record highs, igniting a debate on whether frothy tech valuations could lead to the next big bubble.

Nvidia has hit a new milestone, becoming the first company in the world to reach a market value of $5tn (£3.8tn). The US chip-maker has rapidly climbed from a niche graphics-chip manufacturer to an AI titan, as euphoria about the potential of artificial intelligence keeps driving demand for its chips and propelling its stock to record highs. The company reached a market value of $1tn for the first time in June 2023 and hit the $4tn valuation mark just three months ago . Shares in the chip-maker rose as much as 5.6% to more than $212 on Wednesday morning, boosted by investor optimism about Nvidia's sales in China, which has been a geopolitical flashpoint. The world's most valuable company - the biggest winner in the AI spending spree - has soared past its rivals in the technology sector.

When Sam Altman arrived at Helion Energy's small Redmond, Wash., office in early 2014, nuclear-fusion textbooks tucked under his arm, the company was focusing its efforts on research and development. By the time he left, several days later, he had persuaded the fusion-energy startup to chart a more aggressive path toward deployment, CEO David Kirtley recalls. A year later, Altman, who was co-founding OpenAI around the same time, invested $9.5 million in Helion, taking the role of chairman.

A deepfake video of Nvidia's CEO sent thousands of viewers to a crypto scam Reportedly, the fake video had almost 100,000 live YouTube viewers at one point--far more than the real keynote stream hosted by Nvidia. Nvidia's GPU Technology Conference isn't making many waves for gamer or PC hardware crowds this year, perhaps because it seems to be exclusively interested in boosting hardware for "AI" and data centers. So it's almost ironic that a phony version of the keynote livestream reportedly relied on generative "AI" to fake CEO Jensen Huang and send viewers to a cryptocurrency scam. A YouTube channel calling itself "NVIDIA LIVE" started a livestream shortly after the real Nvidia event began, which users on Twitter reported was a deepfake video of the CEO promoting a "crypto mass adoption event."

Character.AI bans users under 18 after being sued over child's suicide Move comes as lawmakers move to bar minors from using AI companions and require companies to verify users' age The chatbot company Character.AI will ban users 18 and under from conversing with its virtual companions beginning in late November after months of legal scrutiny. The announced change comes after the company, which enables its users to create characters with which they can have open-ended conversations, faced tough questions over how these AI companions can affect teen and general mental health, including a lawsuit over a child's suicide and a proposed bill that would ban minors from conversing with AI companions. "We're making these changes to our under-18 platform in light of the evolving landscape around AI and teens," the company wrote in its announcement. "We have seen recent news reports raising questions, and have received questions from regulators, about the content teens may encounter when chatting with AI and about how open-ended AI chat in general might affect teens, even when content controls work perfectly." Last year, the company was sued by the family of 14-year-old Sewell Setzer III, who took his own life after allegedly developing an emotional attachment to a character he created on Character.AI.

Their antibodies may combat venom from some of the world's deadliest species. There are over 300,000 venomous snakebites reported in sub-Saharan Africa every year. Breakthroughs, discoveries, and DIY tips sent every weekday. Most of today's snakebite antivenoms are far from perfect. Typically manufactured from animal blood plasma, the antidotes often remain expensive, inconsistent, and difficult to scale across multiple snake species .

Crowd control Asses.Masses played by a live audience. Crowd control Asses.Masses played by a live audience. T his weekend, I spent more than eight hours in a theatre playing a video game about donkeys, reincarnation and organised labour with about 70 other people. Political, unpredictable and replete with ass puns, Asses.Masses is, on the one hand, a fairly rudimentary-looking video game made by Canadian artists Patrick Blenkarn and Milton Lim with a small team of collaborators. But the setting - in a theatre, surrounded by others, everybody shouting advice and opinions and working together on puzzles - transforms it into a piece of collective performance art.

Is Trump losing patience with Putin? Will sanctions against Russian oil giants hurt Putin? How much of Europe's oil still comes from Russia? Russia strikes children's hospital in Ukraine as Kyiv hits energy sites A Russian strike on a children's hospital in southern Ukraine has wounded at least nine people, authorities have said, shortly after Kyiv targeted Russian energy sites with drones. Four children were injured in Russia's strike on the medical facility in Kherson on Wednesday, which Ukrainian President Volodymyr Zelenskyy described as a "deliberate" attack that shows Moscow does not want peace.
