World leaders are expected to adopt a new agreement on artificial intelligence when they gather virtually Tuesday to discuss AI's potential risks but also ways to promote its benefits and innovation.

The AI Seoul Summit is a follow-up to November's inaugural AI Safety Summit at Bletchley Park in the United Kingdom, where participating countries agreed to work together to contain the potentially "catastrophic" risks posed by galloping advances in AI.

The European Union opened fresh investigations Thursday into Facebook and Instagram over suspicions that they're failing to protect children online, in violation of the bloc's strict digital regulations for social media platforms.

It's the latest round of scrutiny for parent company Meta Platforms under the 27-nation EU's Digital Services Act, a sweeping set of regulations that took effect last year with the goal of cleaning up online platforms and protecting internet users.

Some social media users are calling out celebrities for what they say is inaction in the face of a humanitarian crisis in Gaza — and they've taken to a "blockout" to pressure the stars to take a stand.

For the blockout, users put a block on seeing any and all content from the accounts of certain celebrities on social media platforms including X, TikTok and Instagram. Some have posted about the celebrities they've blocked, using a hashtag such as #blockout, #blockout2024, or #celebrityblockout, while others have shared posts from users lambasting attendees of high-glamour events like the Met Gala and contrasting it with the situation in Gaza.
