It has been a long time since the threat of using nuclear weapons has been brandished so openly by a world leader, but Vladimir Putin has just done it, warning in a speech that he has the weapons available if anyone dares to use military means to try to stop Russia's takeover of Ukraine.

The threat may have been empty, a mere baring of fangs by the Russian president, but it was noticed. It kindled visions of a nightmarish outcome in which Putin's ambitions in Ukraine could lead to a nuclear war through accident or miscalculation.

Dubai will open the doors Friday to an architecturally stunning building housing the new Museum of the Future, a seven-story structure that envisions a dreamlike world powered by solar energy and the Gulf Arab state's frenetic quest to develop.

The torus-shaped museum is a design marvel that forgoes support columns, relying instead on a network of diagonal beams. It is enveloped in windows carved by Arabic calligraphy, adding another eye-popping design element to Dubai's piercingly modern skyline that shimmers with the world's tallest tower, the Burj Khalifa.

The husband of a cinematographer shot and killed on the set of the film "Rust" says it's "absurd" that Alec Baldwin believes he's not to blame for the shooting and he was "so angry" when Baldwin didn't accept responsibility.

The remarks made in excerpts from an interview with the "Today" show are the first public words from Matt Hutchins on the Oct. 21 death of his wife Halyna Hutchins.

To say Naomi Watts is the only star in "The Desperate Hour" is a little misleading. She's pretty much the only person in the film, that's true. But you could make the case that she has a co-star in her iPhone.

Watts spends most of "The Desperate Hour" furiously typing, listening, consulting, pleading or otherwise glued to her smartphone as it takes on an outsized importance. Alone and lost in the woods, it's her only lifeline to the world.

The logo of Russian state-owned energy giant Gazprom is being removed from the jerseys of German soccer team Schalke following Russia's wide-ranging attack on Ukraine on Thursday.

Schalke said the logo will be replaced by lettering reading "Schalke 04" instead following what it called "recent developments."

Four-time Formula One champion Sebastian Vettel says he will not race in the Russian Grand Prix in September after Russia launched a wide-ranging attack on Ukraine earlier Thursday, hitting cities and bases with airstrikes or shelling.

After President Vladimir Putin defiantly announced he was launching a military operation, Ukraine's government said Russian tanks and troops rolled across the border.

UEFA will no longer host the Champions League final in St. Petersburg after Russia launched a wide-ranging attack on Ukraine on Thursday, the Associated Press has learned.

An extraordinary meeting of the UEFA executive committee will be held on Friday to discuss the geopolitical crisis and when officials are set to confirm taking the May 28 showpiece game out of Russia, a person with knowledge of the process said on Thursday. The person spoke on condition of anonymity to discuss private talks.

Just what a vulnerable world economy didn't need — a conflict that accelerates inflation, rattles markets and portends trouble for everyone from European consumers to indebted Chinese developers and families in Africa that face soaring food prices.

Russia's attack on Ukraine and retaliatory sanctions from the West may not portend another global recession. The two countries together account for less than 2% of the world's gross domestic product. And many regional economies remain in solid shape, having rebounded swiftly from the pandemic recession.

With California entering the third year of severe drought, federal officials said Wednesday they won't deliver any water to farmers in the state's major agricultural region — a decision that will force many to plant fewer crops in the fertile soil that yields the bulk of the nation's fruits, nuts and vegetables.

"It's devastating to the agricultural economy and to those people that rely on it," said Ernest Conant, regional director for the U.S. Bureau of Reclamation. "But unfortunately we can't make it rain."

In the coal fields of eastern Montana, climate change is forcing a stark choice: halt mining that helped build everything from schools to senior centers or risk astronomical future damage as fossil fuel emissions warm the planet and increase disasters, crop losses and premature deaths.

One of the largest mines in this arid region straddling the Wyoming border is Spring Creek -- a gaping hole among sagebrush hills where house-sized mechanical shovels dig up millions of tons of coal annually, much of it shipped overseas and burned in Asian power plants.
