The world's fair in Dubai, a tech-saturated site teeming with talking robots and solar canopies, sought to be the future.

Now, it's history.

Bruce Willis is stepping away from acting after a diagnosis of aphasia, a condition that causes loss of the ability to understand or express speech, his family said.

In a statement posted on Willis' Instagram page, the 67-year-old actor's family announced that Willis was recently diagnosed with aphasia and that it is impacting his cognitive abilities.

Chris Rock received several standing ovations before he told one joke Wednesday at his first comedy show since Will Smith slapped him in the face onstage at the Oscars.

Rock only briefly addressed the slap to the sold out crowd in Boston, saying he was "still kind of processing what happened."

Starting out with funny videos and chat over Mario Kart racing games, two Ukrainian brothers have added a somber tone to their YouTube channel popular with young Japanese with updates from their country that bring the harsh realities of war closer to Japan.

The Russian invasion of Ukraine began just after the duo, Sava Tkachov, 26, and his younger brother Yan, 20, celebrated the second anniversary of their YouTube debut with subscribers exceeding 2 million for their Sawayan Channel and Sawayan Games that Sava hosts.

Will Smith's slap seen 'round the world at the Oscars was clearly a crime, legal experts say, but the chances of prosecution are slim and even if convicted he'd likely face little more than a slap of his own — on the wrist.

Smith left millions of witnesses stunned Sunday when he marched onto the stage of the Dolby Theatre and smacked Chris Rock in the face after the comedian made a joke about his wife, Jada Pinkett Smith, who was sitting with the actor in the front row.

Foo Fighters have canceled all upcoming concert dates following the death of the band's drummer, Taylor Hawkins.

The rockers had been scheduled to play at the Grammy Awards in Las Vegas on Sunday as well as spring dates at the Beale Street Music Festival; the New Orleans Jazz & Heritage Festival; Columbia, Maryland; Raleigh, North Carolina; Daytona Beach, Florida; Charlotte, North Carolina; the Boston Calling Music Festival; and summer dates in Germany, Italy, Spain, Portugal, France and the UK.

Elton John has added 11 new dates on the North American leg of his farewell tour, including concerts in New Jersey, Massachusetts, California, Arizona and Washington state.

John begins his final run of dates in North America in Philadelphia on July 15, finishing with a three-night engagement at Dodger Stadium in Los Angeles on Nov. 17, 19 and 20.

Television ratings for the Oscars rebounded somewhat from last year's record low, but the event clearly doesn't have the appeal to viewers that it once had.

Sunday's ceremony reached an estimated 15.36 million viewers, according to preliminary Nielsen company numbers released by ABC. A more detailed estimate is expected Tuesday, with elements like out-of-home viewing added.

The day after slapping Chris Rock on the Oscars stage and upending the 94th Academy Awards, Will Smith issued an apology to the comedian, to the academy and to viewers at home, saying he was "out of line" and that his actions are "not indicative of the man I want to be."

The fallout from Smith's actions during Sunday's ceremony continued Monday as Hollywood and the public continued to wrestle with a moment that stunned the Dolby Theatre crowd and viewers at home. The Academy of Motion Pictures Arts and Sciences condemned Smith striking Rock, who had made a joke about his wife, Jada Pinkett Smith, and said it would launch an inquiry.

For 30 seconds, the Oscars went silent for Ukraine.

A tribute that started with words from the Ukrainian-born Mila Kunis ended with the Academy Awards fading to black about midway through Sunday's show from Los Angeles, with a plea for anyone watching to do whatever possible to send help to those in the war-torn nation.
