This charging iPad mount turns your car into a mobile movie theater – Kuxiu X97 [Hands-on]

Early last year, Kuxiu released its X33 Pro Max iPad stand. It was the first stand to incorporate pin connectors into a magnetic stand to be able to charge your iPad. It was a fantastic idea. As a stand, it’s built very well, is high quality, does everything you need a stand to do, and gets the job done, but the fact that it also instantly charges the iPad was a game-changer for my setups. But now, they’ve brought the same tech but into your car with a mountable, magnetically charging iPad stand

Is Climate Change an Existential Threat?

If a 60-mile-wide (100-kilometer-wide) asteroid slammed into Earth tomorrow, it would render the planet inhospitable to nearly all life forms, save for the hardiest extremophiles. This mass extinction event would wipe humanity off the face of the Earth—there would be no survivors. To some experts, this is the true definition of an “existential threat.” Traditionalists will say this term describes a risk that endangers the very existence of something—in this case, the human species. In recent ye

This Simple Strategy Could Curb One of Semaglutide’s Worst Side Effects

Semaglutide’s ability to help people lose weight is legendary, but so are the side effects. The active ingredient in medications Wegovy and Ozempic, semaglutide is renowned for causing severe nausea in some people, sometimes to the extent that they stop treatment. But new research published in the journal Diabetes Care suggests there may be a simple way to combat that effect. Led by a team in Israel, the researchers found that giving people more time and flexibility to ramp up to the recommende

Xi Jinping warns against China's overinvestment in EVs and AI

Chinese President Xi Jinping has bluntly questioned a nationwide rush of investment into the AI and EV industries. As deflation anxiety grows and Trump’s trade war with China ramps up, the world’s second largest economy is turning to fast-growth tech industries to remain competitive. But Xi appears to think that the strategy is flawed. As reported by the Financial Times , China's President sent out a pointed message about over-investment at the two-day Central Urban Work Conference in Beijing.

Perplexity’s Comet is the AI browser Google wants

Perplexity sees India as a shortcut in its race against OpenAI

While OpenAI has cemented its lead in the U.S., Perplexity is taking a different route — quietly expanding into India to compete in the next phase of AI adoption. The search-focused AI startup is rapidly adding millions of users in the world’s second-largest internet and smartphone market, positioning itself for mass-market scale. This week, Perplexity partnered with Bharti Airtel, India’s second-largest telecom operator after Reliance Jio, to offer a free 12-month Perplexity Pro subscription —

Uber Is Going All-in on Robotaxis

By the end of this decade, your next Uber ride might not have a driver at all. At least, that’s what Uber wants you (and its investors on Wall Street to believe.) Uber announced a new partnership today with luxury electric vehicle maker Lucid and the robotics company Nuro. Under the agreement, Uber plans to deploy a fleet of at least 20,000 Lucid Gravity SUVs equipped with Nuro’s self-driving technology over the next six years. The robotaxi service is expected to launch in a yet unnamed major U

Uber’s partnership with EV manufacturer Lucid will see it deploy at least 20,000 of the Newark-based company’s vehicles over a period of six years. These will be equipped with the AI-powered Nuro Driver autonomous technology. The vehicles will be owned and operated by Uber or one of its third-party partners, and the service

Uber inks six-year robotaxi deal with Lucid, invests $300 million in EV company

Uber on Thursday announced a partnership to deploy more than 20,000 robotaxis over the next six years as demand for driverless cars kicks into high gear.

5 reasons why I still prefer Perplexity over every other AI chatbot

Stefani Reynolds/Bloomberg via Getty Images I've been working with artificial intelligence (AI) since the 1970s, when Lisp was state-of-the-art. Lately, like everyone else, I've been looking at AI a lot more closely. While it's nifty and getting genuinely useful, it can still blunder, like the time Google's AI Overviews recommended users to eat "at least one small rock per day." AI can also lose its mind, such as when Grok went totally MechnaHitler. Even when I tell J. Random Chatbot to summari

Bank Warns That Robotaxi Companies May Have Overlooked Severe Obstacles to Actually Making Money

Bank Warns That Robotaxi Companies May Have Overlooked Severe Obstacles to Actually Making Money They're not convinced. Cost Benefit As Elon Musk's Tesla triples down on an autonomous ridehailing service, analysts are ringing the alarm bells, warning that even if the technology were swiftly perfected, it could take many years for robotaxis to become profitable. As Business Insider reports, analysts at HSBC warn that the market for driverless taxis — if there even is one — is being "widely ov

Dozens of ‘Ghost Galaxies’ Are Orbiting the Milky Way, Astronomers Suspect

The Lambda Cold Dark Matter (LCDM) theory suggests that most galaxies are low-mass dwarf galaxies, many of which orbit larger galaxies like the Milky Way. More broadly, the LCDM represents our best understanding of how the universe works. But there’s a problem. According to the theory, the Milky Way should have significantly more satellite galaxies than scientists have observed with telescopes and predicted with computer simulations. By combining the highest-resolution supercomputer simulations

AI leadership development platform Praxis Labs sells to Torch

Praxis Labs, a learning development platform, announced its acquisition on Thursday for an undisclosed amount by the leadership and coaching enterprise Torch. “As a small company with fewer than 20 people serving companies as large as Amazon, we knew we needed to build powerful partnerships, across product and go-to-market, to reach more companies,” co-founder and CEO of Praxis Labs, Elise Smith, told TechCrunch about the reason for the sale. She and her co-founder, Heather Shen, met Torch CEO

The Switch 2 Pro Controller does not seem easy to repair at all

The Switch 2 is in many ways a more premium and powerful version of the original Switch, but its sleek design seems to have come at a cost. Not only is the console itself difficult to repair, but a new iFixit teardown video shows that the Switch 2 Pro Controller isn't any easier. Based on iFixit's teardown, you have to completely disassemble the Switch 2 Pro Controller to access the parts you'll likely need to fix first. Accessing the joysticks and battery requires removing an adhesive-secured
