Ukrainian President Volodymyr Zelenskyy has accused Vladimir Putin of "playing games" after the Russian leader proposed a three-day unilateral ceasefire to coincide with Moscow's Victory Day commemorations. "This is more of a theatrical performance on his part. Because in two or three days, it is impossible to develop a plan for the next steps to end the war," Zelenskyy told a small group of journalists on Friday, in remarks embargoed until Saturday. Russia announced a 72-hour halt in hostilities beginning May 8, but has so far rejected an unconditional 30-day ceasefire pushed by Ukraine and the United States, which is trying to broker an end to the three-year war. Zelenskyy said Ukraine would not be "playing games to create a pleasant atmosphere to allow for Putin's exit from isolation on May 9" when some foreign leaders are due in Moscow for Russia's World War II commemorations.

A few years ago, I had the chance to check out the prototype of a reengineered robot vacuum called Matic. The founders, Mehul Nariyawala and Navneet Dalal, had one key insight: People don't care about super-powerful robot vacuums with cool tricks, incredible suction power, and huge docking stations, especially if it means that the vacuum is noisy, loud, or annoying to operate. For a robot vacuum to clean well, it has to be able to navigate a home like a human. That prompted a switch to the Nvidia Jetson Orin chip, which means the vacuum learns how to clean your house on its own. Combined with the fundamentally different hardware design, the result is a game-changing robot vacuum.

Alpha School co-founder Mackenzie Price and a junior at the school Elle Kristine join'Fox & Friends' to discuss the benefits of incorporating artificial intelligence into the classroom. Alpha School uses AI-powered software and devices like these to deliver personalized instruction in just two hours of classroom time per day. TOP OF THE CLASS: At a time when many American students are struggling to keep up, a private school in Texas is doing more with less, much less. At Alpha School, students spend just two hours a day in class, guided by an Artificial Intelligence (AI) tutor. But results are impressive: students are testing in the top 1 to 2% nationally.

Designing concept cars seems kind of like being back in grade school, when kids are encouraged to dream up things like a bedroom with a bouncy-house floor or a spaceship with an ice cream machine on board. At least concept cars have a chance of making it to production at some point, even if that timeline is a long way off. At Kia's EV Day in Barcelona, Spain in March, the brand unveiled a new modular electric van it's calling the Platform Beyond Vehicle (PBV). The PV5 is the first in the automaker's plan, with four variants: Cargo, Passenger, Crew, and a Wheelchair Access Vehicle option. The designers pushed that a little further with the PV5 WKNDR concept, an EV made for camping and overlanding.

Shokz has crept up the wireless audio ranks to become a trendsetter in the sporty earbuds category. Releases like the OpenFit 2 and OpenFit Air were complementary pieces to the brand's excellent bone-conduction headphones. Now, it's taking a page out of Anker's and Bose's playbooks by transitioning into the clip-on earbuds game with the recently launched OpenDots One. These awesome-looking earpieces are built for outdoor runners who want to enjoy music with the full openness of their environment. The OpenDots One clearly find inspiration from the Bose Ultra Open Earbuds, adopting the same earring cuff-like appearance.

The future of law enforcement is here, and it's wearing a robotic face. Around the globe, police forces are integrating artificial intelligence-powered robots into public safety strategies, blending advanced surveillance with real-time threat detection. Thailand has emerged as a key player in this shift, deploying its first AI police robot during the chaotic Songkran festival, a move that raises critical questions about safety, privacy and the role of technology in society. Join the FREE CyberGuy Report: Get my expert tech tips, critical security alerts, and exclusive deals -- plus instant access to my free Ultimate Scam Survival Guide when you sign up! During the Songkran festival, Thailand unveiled AI Police Cyborg 1.0, a stationary robot stationed at Nakhon Pathom's Tonson Road venue.

I feel a troubling kind of opacity in my brain lately--as if reality were becoming illegible, as if language were a vessel with holes in the bottom and meaning was leaking all over the floor. I sometimes look up words after I write them: does "illegible" still mean too messy to read? The day after Donald Trump's second Inauguration, my verbal cognition kept glitching: I got an e-mail from the children's-clothing company Hanna Andersson and read the name as "Hamas"; on the street, I thought "hot yoga" was "hot dogs"; on the subway, a theatre poster advertising "Jan. Ticketing" said "Jia Tolentino" to me. Even the words that I might use to more precisely describe the sensation of "losing it" elude me.

If scientists had a time machine, having a conversation with a Brit from even just 250 years ago could be very confusing. Although they'd be speaking the same language as us, the meaning of many English words have dramatically changed. In fact, the mention of things like'fudge', 'meat', 'pink', 'stripe', 'flirt' and'artificial' in a certain context could send our 18th century ancestors into a muddle. Lynne Cahill, a linguistics professor at the University of Sussex, said some words change their meanings and others don't because'there are lots of things going on'. 'As our lives change, we need words for different things, so some meanings go out of use (think of different types of horse-drawn carriage) and new ones come in (think of technology, like mobile phones and computers),' she told MailOnline. 'Languages deal with these things in different ways, sometimes using existing words with related meanings to refer to new things.' MailOnline has scoured the historical records and dictionaries to find more than 40 words that once had a very different definition.
