Billion-dollar coffins? New technology could make oceans transparent and Aukus submarines vulnerable

Military history is littered with the corpses of apex predators. The Gatling gun, the battleship, the tank. All once possessed unassailable power – then were undermined, in some cases wiped out, by the march of new technology. “Speed and stealth and firepower,” the head of the Australian Submarine Agency, Jonathan Mead, told the Guardian two years ago of Australia’s forthcoming fleet of nuclear submarines. “The apex predator of the oceans.” But for how much longer? In the first quarter of the 21st century, nuclear submarines have proven a formidable force:…

Taipei City council in the dog house over Chinese-made patrol robot

Taipei City council has come under fire after admitting that a robot dog it bought to help patrol city streets using surveillance cameras was made by a Chinese companylinked to the Chinese military. Hammer Lee, the deputy mayor of Taiwan’s capital, introduced a “new patrol partner” for the management and repair of pedestrian areas in a post on Facebook on Tuesday. “This robot, equipped with an optical panoramic survey system, can create 360-degree images, accurately locate facilities, and even automatically report missing items,” Lee said, noting its ability to “accumulate…

Nvidia sets fresh sales record amid fears of an AI bubble and Trump’s trade wars

Nvidia is set to report its second-quarter earnings on Wednesday, in a first test of investor appetite since last week’s mass AI-stock selloff. All eyes will be on the chipmaker’s latest financials as the company sets the tone for the rest of the AI industry after a turbulent week in the sector. Several tech stocks saw shares tumble last week amid growing questions over whether AI-driven companies are being overvalued, including an MIT report that said 95% of AI pilots fail to grow company’s revenues and statements from the OpenAI…

TikTok owner set to launch share buyback valuing company at $330bn

ByteDance, the owner of the short-video app TikTok, is set to launch a new employee share buyback that will value the Chinese technology giant at more than $330bn, driven by continued revenue growth, said three people with knowledge of the matter. The company plans to offer current employees $200.41 per share in the repurchase program, the people said, up 5.5% from $189.90 each it offered them about six months ago which valued ByteDance at roughly $315bn. The buyback is expected to be launched in the autumn. The latest buyback at…

Box, run, crash: China’s humanoid robot games show advances and limitations

A quick left hook, a front kick to the chest, a few criss-cross jabs, and the crowd cheers. But it is not kickboxing prowess that concludes the match. It is an attempted roundhouse kick that squarely misses its target, sending the kickboxer from a top university team tumbling to the floor. While traditional kickboxing comes with the risk of blood, sweat and serious head injuries, the competitors in Friday’s match at the inaugural World Humanoid Robot Games in Beijing faced a different set of challenges. Balance, battery life and a…

Trump sparks concern after suggesting he might allow sales of Nvidia’s advanced AI chips in China

Donald Trump has suggested he might allow Nvidia to sell chips in China that are more technology advanced than currently permitted, despite deep-seated fears in Washington that Beijing could harness US artificial intelligence capabilities to supercharge its military. In a briefing on Monday, the president suggested he could “make a deal” for Nvidia to sell a downgraded version of its flagship Blackwell chip in China. The move could open the door to China securing more advanced computing power from the US, even as the two countries battle for technology supremacy,…

Nvidia and AMD agree to pay 15% of China chip export revenues to US

The chipmakers Nvidia and AMD have agreed to give the US government 15% of their revenue from advanced chips sold to China in return for export licences to the key market. The unprecedented move, an apparent reversal of US national security restrictions on the chip sales, signalled an easing in the US-China trade war. Donald Trump has weaponised trade restrictions and tariffs to bring business to US shores. However, the quid pro quo arrangement, first reported by the Financial Times, is potentially unconstitutional. The arrangement will lead to Nvidia giving…

Maglev train researchers may have solved ‘tunnel boom’ shock waves

Researchers hope they may have solved the “tunnel boom” problem as they prepare to roll out China’s latest prototype magnetic levitation train. The newest version of the maglev train is capable of travelling at 600km/h (about 370mph). However, the train’s engineers have wrestled with the problem of the shock waves which occur as the train exits the mouth of a tunnel. When a high-speed train enters an enclosed space such as a tunnel, air in front is compressed, like in a piston. The resulting fluctuations in air pressure coalesce at…

Chinese carmakers led by BYD report big rises in UK sales in July

Chinese carmakers led by BYD reported big jumps in UK sales last month, despite a declining overall car market, including a 59% slump in sales from their electric vehicle rival Tesla. BYD sales quadrupled year on year to reach 3,200 in July, even as overall sales of all types of car declined by 5% to 140,000, according to data published on Tuesday by the Society of Motor Manufacturers and Traders (SMMT), a lobby group. The car industry has said it is struggling with a weak economy, which is holding back…

China calls for global AI cooperation days after Trump administration unveils low-regulation strategy

Chinese premier Li Qiang has proposed establishing an organisation to foster global cooperation on artificial intelligence, calling on countries to coordinate on the development and security of the fast-evolving technology, days after the US unveiled plans to deregulate the industry. Speaking at the annual World Artificial Intelligence Conference (WAIC) in Shanghai, Li called AI a new engine for growth, adding that governance is fragmented and emphasising the need for more coordination between countries to form a globally recognised framework for AI. Li warned Saturday that artificial intelligence development must be…
