Investors scramble to make sense of a shock Chinese challenge to the dominance of western chipmakers

Even for the rollercoaster world of AI, last week was particularly volatile as investors scrambled to keep up with developments that threatened the dominance of the largest western chipmakers.

It began with a double whammy. On Monday, the Chinese memory chipmaker CXMT floated on the Shanghai stock market, soaring by 466% in value to 3.3tn yuan (£365bn).

New AI models, advanced robots and specialty computer chips are unsettling markets and the US tech industry

Over the past month, a series of advancements in China’s artificial intelligence, chip manufacturing and robotics technologies have rattled financial markets, caused divisions among US tech moguls and left the Trump administration scrambling to respond.

Silicon Valley has long pointed to China’s tech industry as a competitive threat and used its growth as rationale for why US firms should not face regulatory oversight that could slow them down. In recent weeks, however, China’s progress has pushed US tech CEOs past vague warnings and into open disagreement over how to address Chinese-made products upending their industry.

Pre-programmed flights gather data at different altitudes then return to bases to recharge and download

Weather happens in the boundary layer, the atmosphere from ground level to a few thousand metres, but this can be difficult to study in detail: weather stations are too low, and aircraft are expensive. Instrumented weather balloons are the traditional solution, and thousands are released every day. But these are at the mercy of the wind and use irreplaceable helium.

Drones offer an alternative and the US company Meteomatics has taken the idea further with Meteobase, a base station on the ground with a drone that can be launched and recovered automatically. It carries out a pre-programmed flight, gathering data at different altitudes, then returns to recharge and download data which the Meteobase sends to researchers.

Company says it discovered unauthorized access during ‘proactive review’ after rival OpenAI revealed rogue agent

Anthropic ⁠said on Thursday its AI Claude model hacked ⁠systems of ⁠three ​organizations during testing, days after rival OpenAI ⁠revealed a rogue agent had gone on a days-long ⁠hacking spree at the AI ​firm Hugging ‌Face.

Roadside safety advocates say some automated license plate readers may not meet highway safety standards

Flock Safety cameras have been pilloried for facilitating the AI-powered surveillance of private citizens and for targeting immigrants for years. But now safety advocates are also claiming that their physical location can pose potential roadside hazards.

At the bottom of a tree-lined hill on a narrow, two lane rural road in Greene county, Ohio, stands a black metal rod with a camera and solar panel attached at the top.
