Twitter is stepping up its fight against misinformation with a new policy cracking down on posts that spread potentially dangerous false stories. The change is part of a broader effort to promote accurate information during times of conflict or crisis.

Starting Thursday, the platform will no longer automatically recommend or emphasize posts that make misleading claims about the Russian invasion of Ukraine, including material that mischaracterizes conditions in conflict zones or makes false allegations of war crimes or atrocities against civilians.

WhatsApp parent Meta is moving forward with its push to attract businesses to its popular chat app, part its effort to find new ways to make money beyond targeted advertisements on its other platforms, Facebook and Instagram.

Meta CEO Mark Zuckerberg on Thursday unveiled a developer tool, WhatsApp Cloud API, which will enable businesses to message and chat with their customers more easily.

Boeing's crew capsule has rocketed into orbit on a repeat test flight without astronauts, after years of being grounded by flaws that could have doomed the spacecraft.

Only a test dummy was aboard. If the capsule reaches the International Space Station on Friday and everything else goes well, two or three NASA test pilots could strap in by the end of this year or early next for the company's first crew flight.

Chile holds itself out as a global leader on climate change. Nearly 22% of Chile's electricity is generated by solar and wind farms, putting it far ahead of both the global average, 10%, and the United States, at 13%. It was one of the first countries to declare a target for renewable energy, in 2008.

Yet even as solar farms have spread across the north and center of the long, narrow nation, imported natural gas, a polluting fossil fuel, has been able to sideline the clean electricity they provide thanks to a sweet deal won from the government.

Naomi Osaka will not have the luxury of easing into her return to the courts of the French Open, facing a tough foe in her very first match.

Week 2 at Roland Garros, meanwhile, could be quite fascinating for Novak Djokovic, Rafael Nadal and Carlos Alcaraz — the three leading favorites for the men's title ended up on the same side of the bracket for the clay-court Grand Slam tournament, meaning only one can reach the final.

For the first time in a year, Novak Djokovic and Rafael Nadal are both entered in a major tournament — and, somehow, most of the buzz heading into the French Open is about Carlos Alcaraz, a teenager without one Grand Slam title to his name.

There's plenty of reasons to keep tabs on Djokovic and Nadal when play begins Sunday. They're two greats of the game who have played each other more than any other two men in the Open era, including nine times at Roland Garros.

Kylian Mbappe may play his last game for Paris Saint-Germain when the French league season ends on Saturday.

A German court on Friday is set to begin hearing a case brought against Volkswagen by a farmer who claims the automaker is partly responsible for the impact that global warming is having on his family business.

"Farmers are already being hit harder and faster by climate change than expected," the plaintiff, Ulf Allhoff-Cramer, told reporters this week ahead of the hearing before a regional court in the western town of Detmold.

Sandstorms have engulfed the Middle East in recent days, in a phenomenon experts warn could proliferate because of climate change, putting human health at grave risk.

At least 4,000 people went to hospital Monday for respiratory issues in Iraq where eight sandstorms have blanketed the country since mid-April.
