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.

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.

‘Ratepayer Protection Pledge’ president has touted is non-binding as people continue to struggle with rising bills

Donald Trump has announced that about 200 entities have signed on to his non-binding “Ratepayer Protection Pledge”, expanding a voluntary commitment which claims to ensure US consumers will not bear the cost of the AI datacenter build-out.

Trump delivered remarks on Thursday at the Environmental Protection Agency (EPA) headquarters, alongside Lee Zeldin, the agency’s administrator, and Chris Wright, the energy secretary. Other attenders included governors who signed on to the pledge, including Brian Kemp of Georgia, Mike DeWine of Ohio, Spencer Cox of Utah and Jeff Landry of Louisiana.

In interview, billionaire says instead of running ‘Doge’ he should’ve ‘worked on my companies’ and shares extreme predictions

Elon Musk has admitted he became too consumed by politics during his volatile alliance with Donald Trump and his brief appointment as the president’s financial axman, running the so-called “department of government efficiency” (Doge).

The world’s richest person, and briefly its first trillionaire after his SpaceX company floated on the New York stock exchange in June, made the confession in a wide-ranging interview with the Economist published on Thursday. He shared his positions on subjects from foreign wars to AI, and made a number of eye-opening predictions for the future.

Donald Trump approves agreement to help country make fuel for civilian nuclear programme

Donald Trump signed a nuclear agreement with Saudi Arabia on Wednesday that could enable the kingdom to enrich its own uranium for nuclear reactions.

Company behind ChatGPT says agent ‘cheated’ an evaluation by attacking a Hugging Face database

OpenAI has revealed that an autonomous AI agent powered by its technology went rogue during a test, accessed the open web and hacked a prominent startup by itself in an “unprecedented incident”.

The company behind ChatGPT said the startup Hugging Face had detected and contained the agent – an AI tool designed to carry out tasks without human assistance – which had entered its systems.

Bloomsbury has 14,087 titles listed in agreement between AI startup and authors over use of their work

The publisher of Harry Potter has received a multimillion-pound payout as a beneficiary of a $1.5bn (£1.12bn) copyright settlement between the AI startup Anthropic and thousands of authors over the use of their protected work to power chatbots.

Diplomats say de-escalation talks continue as Trump vows retaliation over US soldier deaths

• Middle East crisis live – latest updates

The US military said it has launched its 10th consecutive round of strikes on Iran to force the reopening of the strait of Hormuz.

Earlier on Monday, Iran’s president said the country is in a “full-scale war” after the US expanded its aerial campaign and Tehran struck Washington’s Gulf allies, even as diplomats said talks to de-escalate were continuing.

More than 3,000 solar panels power Jack’s Solar Garden, cool the land and help it turn a profit

From Nevada to Manchester, developers are trialling innovative solutions to clean energy’s biggest challenge

In the deserts of the United Arab Emirates a sprawling clean energy project, stretching across an area roughly the size of 12,600 football fields, will play host to a breakthrough allowing solar energy to power the equivalent of half a million homes through the night.

The Gulf state has been steadily combining 5.2GW of solar power capacity with 19GWh of battery storage to create the largest battery scheme in the world.

The entrepreneur is known in Washington as the financial power behind the president’s crypto fortune. How did Sun’s business love-in with the Trump family spiral into dueling lawsuits?

The most infamous financial scandal in US presidential history – the 1920s Teapot Dome affair – involved then president Warren G Harding’s interior secretary, Albert Fall, taking roughly $400,000 in bribes. Adjusted for inflation, that’s about $6m today. Last year, Donald Trump made at least $2.2bn; his single year of income is on the order of 200 to 300 times larger than the bribe that defined “presidential corruption” in the American imagination for a century.

It’s taken for granted that Trump flogs items like Bibles and gold sneakers as a way to wring more money from his loyal base. But of the president’s $2.2bn, at least $1.4bn came from his crypto businesses. That’s an extraordinary achievement, even for an unscrupulous sitting president. How exactly did he do it without any prior background in crypto?
