LONDON — Sadiq Khan, the Labour Party’s mayor of London, romped to victory Saturday, securing a record third straight term at City Hall, on another hugely disappointing day for the U.

In the past few days, you may have noticed something new inside Meta’s apps, including Instagram, Messenger and WhatsApp: an artificially intelligent chatbot. Within those apps, you can chat with Meta AI and type in questions and requests like “What’s the weather this week in New York?” or “Write a poem about two dogs living in San Francisco.” The assistant will come up with responses immediately, such as “The corgi was short, with a butt so wide, the lab was tall, with a tongue that would glide.” You can also instruct Meta AI to produce pictures — like an illustration of a family watching fireworks. This is Meta’s response to OpenAI’s ChatGPT, the chatbot that upended the tech industry in 2022, and similar bots including Google’s Gemini and Microsoft’s Bing AI.

RIYADH, Saudi Arabia — On a Monday morning last month, tech executives, engineers and sales representatives from Amazon, Google, TikTok and other companies endured a three-hour traffic jam as their cars crawled toward a mammoth conference at an event space in the desert, 50 miles outside Riyadh, Saudi Arabia. The lure: billions of dollars in Saudi money as the kingdom seeks to build a tech industry to complement its oil dominance. To bypass the congestion, frustrated eventgoers drove onto the highway shoulder, kicking up plumes of desert sand as they sped past those following traffic rules.

For more than 50 years, the National Sports Center for the Disabled has been a world leader in adaptive snow sports at Winter Park, helping people with disabilities become active outdoors, offering competitive programs and producing paralympic athletes. Now it’s poised to expand its programs in the Front Range with a spacious new facility at the Jefferson County Fairgrounds. The NSCD Adaptive Program Center opened Wednesday with a field day for 100 special needs students from Aurora Public Schools.

A high school athletic director in Maryland has been accused of using artificial intelligence to impersonate a principal on an audio recording that included racist and antisemitic comments, authorities said last month. Authorities said the case appears to be among the first of its kind in the country and called for new laws to guard against the technology.
