Elon Musk said a third person has received an implant from his brain-computer interface company Neuralink, one of many groups working to connect the nervous system to machines.

"We've got ... three humans with Neuralinks and all are working well," he said during a wide-ranging interview at a Las Vegas event streamed on his social media platform X.

President-elect Donald Trump has expressed frustration that flags will be flying at half-staff when he takes office later this month.

It's an action put in place by President Joe Biden to honor the late President Jimmy Carter, who died last month at 100. It's not a timeline that Trump can do anything about — until after he takes office — although a large U.S. flag at Trump's home in Florida has been raised to full height following Carter's burial.

U.S. wholesale inflation rose last month on higher energy prices.

The Labor Department reported Tuesday that its producer price index — which tracks inflation before it hits consumers — rose 0.2% last month from November, down from a 0.4% gain the month before. Compared to a year earlier, producer prices rose 3.3%, biggest jump since February 2023 and up from a 3% gain in November.

U.S. President Donald Trump will take part virtually in the World Economic Forum's annual meeting in Davos just days after his inauguration, the forum president said Tuesday.

Børge Brende, a former Norwegian foreign minister who heads the Geneva-based organization, noted that Trump had twice attended the elite gathering of business and government leaders in-person during his first term.

Spain is planning a raft of measures to address its brewing housing crisis, including an up to 100% tax on properties bought by non-European Union residents.

Spanish Prime Minister Pedro Sánchez announced the plan this week to tackle housing affordability and high rents in the Southern European nation. He said that the overall goal was to provide "more housing, better regulation and greater aid."

Secretary of State Antony Blinken is set to make a last-minute case Tuesday for a plan for the post-war reconstruction and governance of Gaza as a ceasefire between Israel and Hamas appears tantalizingly close to completion.

Blinken will tout the proposal, which has been in the works for a year, and discuss the importance of ensuring its success after the Biden administration leaves office in a speech to the Atlantic Council, a Washington-based think tank, according to a U.S. official, who spoke on condition of anonymity to preview the speech.

Lebanon's new prime minister pledged Tuesday to extend state authority over all Lebanese soil after a November ceasefire ended a war between Hezbollah and Israel.

Nawaf Salam, in his first speech, said he would "extend the authority of the Lebanese state across all its territory" and "work seriously to completely implement U.N. resolution 1701" calling for Hezbollah to withdraw from south Lebanon.

Hamas has accepted a draft agreement for a ceasefire in the Gaza Strip and the release of dozens of hostages, two officials involved in the talks said Tuesday. Mediator Qatar said the negotiations were at the "closest point" yet to sealing a deal.

The Associated Press obtained a copy of the proposed agreement, and an Egyptian official and a Hamas official confirmed its authenticity. An Israeli official said progress has been made, but the details are being finalized. The plan would need to be submitted to the Israeli Cabinet for final approval.

Palestinian activists and residents have planted a grove of 250 olive trees in a northern West Bank town in memory of the late U.S. President Jimmy Carter, describing him as a staunch supporter of the Palestinian cause.

The former president's legacy is "rooted" among Palestinians and across the globe, said Abbas Melhem, executive manager of the Palestinian Farmers Union. Carter was one of the few world leaders who "stood firmly supporting the struggle of the Palestinians for independence and for freedom," he said.

The defense ministers of Europe's five top military spenders have said they want to continue increasing their investments in defense but described meeting President-elect Donald Trump's challenge for them to raise spending to 5% of their overall economic output as complicated.

The defense ministers of Germany, France, Britain, Italy and Poland came together Monday near Warsaw for a meeting in a new format that they established after Trump was re-elected last year. Their first meeting in this format of five NATO members was held in Berlin in late November.
