Sen. Bernie Sanders' presidential campaign said this week that he will participate in the next Democratic primary debate on Oct. 15 in Westerville, Ohio, after spending 3 nights in a Las Vegas hospital following a heart attack, per the New York Times.

What's happening: The 78-year-old, released from the hospital on Friday, underwent a medical procedure after a blockage was found in one of his arteries. Senior campaign adviser Jeff Weaver said all upcoming campaign events are suspended "until further notice." His wife, Jane Sanders, released a statement during his hospitalization on Thursday saying there is no need for further procedures.

“After two and a half days in the hospital, I feel great, and after taking a short time off, I look forward to getting back to work."
— Sanders' statement on Friday
"Bernie is up and about. Yesterday, he spent much of the day talking with staff about policies, cracking jokes with the nurses and doctors, and speaking with his family on the phone. His doctors are pleased with his progress, and there has been no need for any additional procedures. We expect Bernie will be discharged and on a plane back to Burlington before the end of the weekend. He'll take a few days to rest, but he's ready to get back out there and is looking forward to the October debate."
— Jane Sanders' statement on Thursday

Prior coronavirus infections may not protect well against Omicron

Illustration: Aïda Amer/Axios

New data from South Africa suggests the Omicron variant spreads more than twice as quickly as the Delta variant, and that immunity from prior infection doesn't appear to protect a person very well against Omicron variant.

Why it matters: The findings are extremely preliminary, and there are still many open questions about how well vaccines work against the variant. But these initial breadcrumbs of data are helping the world begin to understand what it's up against.

AI could end foreign-language subtitles

AI companies are developing methods to translate and synthesize voices in ads, movies and TV.

Why it matters: The advances in voice synthesis could help fix bad movie dubbing — and they come as international content is becoming increasingly important to studios and streaming platforms as part of the globalization of entertainment.

A dark view of the future of autonomous weapons

A still from the video "If Human: Kill ( )." Image: Future of Life Institute

A new short film warns of the coming risks posed by the development and proliferation of lethal autonomous weapons.

Why it matters: Drones with the ability to autonomously target and kill without the assistance of a human operator are reportedly already being used on battlefields, and time is running out to craft a global ban of what could be a destabilizing and terrifying new class of weapon.
