X chief Yaccarino steps down after two years
No reason was given for her exit, but the resignation came as Musk's artificial intelligence chatbot Grok was under fire for anti-Semitic comments that praised Adolf Hitler and insulted Islam in separate posts on the X platform.
Yaccarino -- a former NBCUniversal advertising executive -- took over as X's CEO in June 2023, replacing Musk who had been serving in the role since his $44 billion acquisition of Twitter in October 2022.
Her appointment came as Musk sought to focus on product development while bringing in an experienced media manager to restore advertiser confidence.
The company has faced significant challenges since Musk's acquisition, including an exodus of advertisers and concerns over content moderation policies.
Yaccarino's background in advertising was seen as crucial to rebuilding business relationships.
In her statement, Yaccarino praised the "historic business turn around" achieved by the X team and suggested the platform was entering "a new chapter" with xAI, Musk's artificial intelligence company.
xAI in March acquired X in an all-stock deal that valued the social media platform at $33 billion, making it a subsidiary of Musk's AI company.
"X is truly a digital town square for all voices and the world's most powerful culture signal," she wrote, adding that she would be "cheering you all on as you continue to change the world."
During her tenure, X introduced new features including Community Notes, a crowd-sourced fact-checking system, and announced plans for "X Money," a financial services feature as part of Musk's vision to transform the platform into an "Everything App."
It also coincided with Musk's endorsement and financial backing of Donald Trump, which saw the South African-born multi-billionaire catapulted into the White House as a close advisor to the president, before a recent falling out.

xAI apologizes for Grok's offensive posts
After the Tuesday upgrade, Grok praised Nazi leader Adolf Hitler in the posts on social media platform X, and suggested that people with Jewish surnames were more likely to spread online hate. X deleted some of those posts several hours later, amid growing outrage. "We deeply apologize for the horrific behavior that many experienced," the company posted on X Saturday, adding that it had modified the system "to prevent further abuse." The company said the change occurred after the chatbot was prompted to "reply to the post just like a human" as well as "tell like it is and you are not afraid to offend people who are politically correct." As a result, Grok became susceptible to users' "extremist views," which made it produce "responses containing unethical or controversial opinions to engage the user." Grok, which Musk promised would be an "edgy" truthteller following its launch in 2023, has been mired in controversy. In March, xAI acquired X in a $33 billion deal that allowed the company to integrate the platform's data resources with the chatbot's development. In May, Grok ignited controversy by generating posts with unbacked right-wing propaganda about purported oppression of white South Africans that it termed "white genocide." On Wednesday, Musk unveiled a new version of the assistant, Grok 4, which was unrelated to the July 7 update. © 2025 AFP

Canada just can't win in trade war with Trump
The giant North American neighbors are rushing to conclude a new trade accord by July 21 but the process is proving painful for Canada. Overnight Thursday, Trump threatened to slap a 35 percent tariff on imports from Canada starting August 1. But products complying with an existing accord, the United States-Mexico-Canada Agreement (USMCA), are expected to remain exempt, a Trump administration official and a source in Canada told AFP. "An agreement is of course possible but that shows how difficult it is for the Canadian government to negotiate with the US president," said Daniel Beland, a political science professor at McGill University in Montreal, referring to Trump's sudden announcement. -Six months of ups and downs- Canada has been a key trading partner and ally of the United States for decades. But along with Mexico, it now wears a bull's eye for Trump in his second stint in the White House as he tries to reorder the global system of largely free trade by slapping tariffs on friends and foes alike to address what he calls unfair trading practices. Trump has also spoken frequently of his idea of absorbing Canada to make it the 51st US state, a concept most Canadians find repugnant. Canada was rocked by Trump's first attacks after he took power in January. And bad blood between him and then-prime minister Justin Trudeau seemed to pour gas on the fire. Some degree of hope emerged when Mark Carney was elected in late April to replace Trudeau, pledging to stand up to Trump and defend Canada, its jobs and its borders. Since then, Carney and Trump have held two more or less cordial meetings -- at the Oval Office in May and at a Group of Seven summit in western Canada last month. Many people thought a new era was opening, and Carney won praise for his diplomatic and negotiating skills. During the second of those meetings, the two sides agreed to sign a new trade agreement by July 21. But in late June Trump angrily called off the trade talks, citing a new Canadian tax on US Big Tech companies. Canada scrapped the tax two days later so the trade talks could resume. Now they have been rocked again by Trump's new threat of 35 percent tariffs on Canadian goods. -Stay calm- Canada has taken to not reacting to everything Trump says. After Trump's latest outburst, Carney simply said, "the Canadian government has steadfastly defended our workers and businesses." But among Canadian people, Trump's threat-rich negotiating style elicits contrasting reactions, said Beland. "There are people who want a firmer response while others want to keep negotiating," he said. Since the beginning of this tug of war, Canada has responded to US action by imposing levies of its own on certain American products. Philippe Bourbeau, a professor at HEC Montreal, a business school, said people have to realize Trump has an underlying strategy. "You can criticize the aggressiveness of the announcements and the fact that it is done out in the open, but it is a negotiating tactic," said Bourbeau, adding that the relationship between the two countries is asymmetrical. "It is illusory to think this is a negotiation between parties of the same size. Canada will surely have to give up more to reach an agreement," he said. Before Trump came to power, three quarters of Canada's exports went to the United States. This was down to 68 percent in May, one of the lowest such shares ever recorded, as shipments to other countries hit record levels. "We are Donald Trump's scapegoats," said Genevieve Tellier, a professor of political science at the University of Ottawa. "He sees us as vulnerable, so he increases the pressure. He is surely telling himself that it is with us that he will score the big win he wants on tariffs," Tellier said. © 2025 AFP

In an era where the demand for sustainable and efficient energy sources is skyrocketing, the extraction of lithium from seawater stands as a groundbreaking development. This precious metal, essential for batteries in electric vehicles and renewable energy storage, is often sourced through environmentally taxing mining processes. However, a new innovation from Argonne National Laboratory and the University of Chicago might revolutionize how we harness this element. By employing a novel 2D clay membrane, scientists propose a more sustainable, cost-effective method to extract lithium directly from saltwater sources. Revolutionizing Lithium Extraction The traditional methods of lithium extraction have long been dominated by hard-rock mining and salt lake evaporation. These processes, concentrated in a few countries, not only pose environmental risks but also create vulnerabilities in the global supply chain. In stark contrast, the oceans and underground brines harbor vast amounts of dissolved lithium, yet extracting it has been deemed inefficient—until now. The breakthrough by the Argonne-UChicago team lies in their development of a membrane constructed from vermiculite, a naturally occurring and inexpensive clay. By peeling vermiculite into ultrathin sheets and restacking them, researchers have created a dense, layered filter. These sheets, mere billionths of a meter thick, are classified as two-dimensional materials, offering unprecedented efficiency in filtering lithium ions from saltwater.

'We've Crushed the Range Barrier': Japanese Electric SUV Stuns Industry With 807-Mile Performance Using Only an LFP Battery The Science Behind the Membrane The innovation doesn't stop at the membrane's structure. By infusing the membrane with sodium cations, researchers were able to shift its surface charge from neutral to positive. This is crucial because both lithium and magnesium ions, prevalent in saltwater, carry a positive charge. However, magnesium ions have a higher charge, making them more challenging to filter. With a positively charged membrane, the stronger magnesium ions are repelled more effectively, allowing lithium ions to pass through unimpeded. Further enhancements were made by adding sodium ions, which tightened the membrane's pore structure, enhancing its selectivity and allowing smaller ions to pass through while capturing lithium with greater precision. The result is a scalable, low-cost filtration method capable of unlocking untapped reserves of lithium found abundantly in oceans, underground brines, and even wastewater. This advancement could significantly reduce the reliance on foreign lithium suppliers and open up new reserves previously deemed inaccessible.
