Does'America First' make the US weaker? Who is Marjorie Taylor Greene? Former United States Treasury Secretary Larry Summers has resigned from the OpenAI board, days after US President Donald Trump ordered the Justice Department to investigate his and other prominent Democrats' ties to convicted sex offender Jeffrey Epstein. The outlet Axios first reported the resignation on Wednesday. Anthropic's AI hacking claims divide experts We appreciate his many contributions and the perspective he brought to the Board," OpenAI's board of directors said in a statement. The move comes one day after the Republican-controlled US Congress voted almost unanimously to force the release of Department of Justice files on Epstein, an outcome Trump had fought for months before ending his opposition. He has served on the OpenAI board since late 2023, following the brief removal of the ChatGPT maker's CEO, Sam Altman. Other prominent companies with ties to Summers include edu-tech firm Skillsoft, where he has been a board member since 2021, and Santander, where he chairs the bank's international advisory board. He was also a former president of Harvard University. The resignation comes after Summers announced that he would step back from all other public commitments to "rebuild trust and repair relationships with the people closest to me". "Everyone in Washington has known who Larry Summers is for decades.

My parents didn't go to college, but his father was a pediatrician, Jewish American. His mother was an artist that still is an artist, and she's African American. So he is Black and Jewish parentage. He is dyslexic, and that's a big part of his identity. And when we talked about going to Central High School, which is kind of a magnet school, it's all academic, and it draws from all over the city.

The grand challenge facing global agriculture today is the need to increase food production to feed a rapidly growing population, amid diminishing natural and human resources and climate pressures. With the global population expected to exceed 9.5 billion by 2050, and with several key resources being depleted (see sidebar), the agricultural community is turning to a digital revolution to secure the future of our food production. Touted Agriculture 4.0, this new movement is deploying digital technologies at scale, including field and aerial sensing, automation, and other smart devices to monitor and track resources and to improve operational efficiency. Artificial intelligence (AI) technologies are playing a central role in driving this revolution: enabling real-time decision support using spatiotemporal data collected on farms, augmenting human labor with automated decision making and robotics, estimating and forecasting risks due to extreme weather, and aiding in longer-term planning under climate-imposed uncertainties. To propel the development and deployment of AI tools and technologies for U.S. agriculture, since 2020 the U.S. Department of Agriculture's National Institute of Food and Agriculture (USDA NIFA) has made a strategic investment in five AI institutes.

Why quasicrystals shouldn't exist but are turning up in strange places Matter with "forbidden" symmetries was once thought to be confined to lab experiments, but is now being found in some of the world's most extreme environments In autumn 1945, Lincoln LaPaz crouched over a patch of scorched ground in the Jornada del Muerto desert of New Mexico. LaPaz, an astronomer, was out hunting for meteorites. He had spotted something in the dust: a strange, glittering crust of blood-red glass. This was no meteorite, but it was striking enough that he held onto it. It wasn't until decades later that anyone would realise quite how special LaPaz's chance find was.

How generative AI in Arc Raiders started a scrap over the gaming industry's future Don't get Pushing Buttons delivered to your inbox? A rc Raiders is, by all accounts, a late game-of-the-year contender. Dropped into a multiplayer world overrun with hostile drones and military robots, every human player is at the mercy of the machines - and each other. Can you trust the other raider you've spotted on your way back to humanity's safe haven underground, or will they shoot you and take everything you've just scavenged? Perhaps surprisingly, humanity is (mostly) choosing to band together, according to most people I've talked to about this game.

The hot spot seemed the perfect place for Yuletide-loving royalists. But, as with the Eiffel Tower in Beijing and some of the most picturesque windmills in the Netherlands, there was much less to it than first met the eye ... Yes: broad paths lined with wooden huts, festooned with lights and Christmas trees, "a beautiful winter wonderland atmosphere" - all within the forecourt of the royal palace. It sounds almost too good to be true. But look at the picture! Where are all those lights hanging from?

In the face of heavy travel restrictions imposed by the Trump administration, the United States announced that World Cup ticket holders will get expedited processing for their visas. Gianni Infantino, the president of FIFA, visited the White House this week to announce with an initiative with Donald Trump that would give priority to World Cup ticket holders next year to process a US visa. This initiative is called "FIFA Pass." "FIFA Pass is a prioritized appointment scheduling system," Infantino said from the Oval Office. "So if you have a ticket for the World Cup, you can have a prioritized appointment to get your visa. Because, you said it the first time we met, Mr. President, America welcomes the world."
