US vice-president’s comments come as former Anthropic researcher revisits recent claim AI could destroy humanity

The US vice-president has dismissed calls for global regulation of AI safety risks, telling companies creating the most advanced models: “If you’re building Frankenstein, stop.”

In remarks addressed towards Dario Amodei, the co-founder of Anthropic who has called on Washington DC to coordinate control of AI systems, including with China, JD Vance said: “If you’re gonna create Frankenstein, don’t come to the government and say we need regulation.”

Firms manage $7.3tn in assets and could afford to transition away from fossil fuels yet invest in natural gas and coal-fired plants to power datacenters

The energy portfolios of 20 private equity firms produce 1.5bn tons of greenhouse gases a year, more than the annual emissions of any country except China, the US, India and Russia, according to a new report.

Together, these firms manage $7.3tn in assets of all kinds, affording them the ability to shape the pace of the transition away from fossil fuels. However their energy investments include significant fossil fuel assets including natural gas and coal-fired power plants to provide electricity to datacenters.

Trump’s EPA strips itself of regulating ability, gutting Clean Air Act in what experts say is a gift to planet polluters

On the heels of the hottest summer ever recorded in the US, the Trump administration has said it will erase any limits on emissions from coal and gas plants that are dangerously heating up our planet.

The US Environmental Protection Agency said it will strip itself of its ability to regulate greenhouse gas emissions coming from power plants under the Clean Air Act, removing a key tool to address the climate crisis.

The subversive bacchanal for San Francisco’s eccentric underground is ageing out amid an influx of the super-rich

Burning Man, the infamous arts festival in the Nevada desert, turned 40 this year, and it’s showing some distinct signs of middle age.

It’s not just the tech billionaires who show up to party, the chartered flights straight to the desert or the HBO documentary about behind-the-scenes power struggles. The tens of thousands of people who assemble each year to create a tent city in the wilderness appear to be growing older, and it doesn’t seem that they’re being replaced by as many younger “burners”, as festival participants are called.

Trump’s toga | Reform UK donations | Ben Delo | Word watch | Andy Burnham | The name game

Octavian (later Emperor Augustus), following his victorious battles of Illyricum and Actium, announced he would give 400 sesterces to adult male citizens. Will we see the US president wearing an emperor’s purple and gold toga soon (Trump promise of $5,000 for US citizens after midterms decried as ‘bribery’, 10 September)?

• Can we assume that the donations to Reform UK from the billionaires Christopher Harborne and Ben Delo (Report, 12 September) will be followed by some sort of cash offer for every adult in the UK should Mr Farage win the next election?

Silicosis sufferers are getting younger as Trump and the coal mining industry push back on protections

Silicosis is one of the oldest workplace hazards and public health experts have known for decades how to prevent it. Yet a new wave of workers, from Appalachian coalminers to Latino countertop fabrication workers, are developing and dying from the disease as industry fights new protections and regulators fail to defend the rules that could protect them.

John Robinson’s grandfather developed black lung back when coalminers could spend decades in the mines before being diagnosed with the disease, often dying in their 60s, 70s and 80s. But Robinson, who mined for coal in south-west Virginia, was diagnosed when he was 47. He’s part of a trend that has grown over the past two decades in central Appalachia, where more coalminers are developing black lung disease at younger ages.

Michigan case is one of several legal disputes as Trump administration uses emergency powers to force a half-dozen coal-fired plants from closing

In a defeat for the Trump administration, a federal court on Friday ruled that the energy department exceeded its authority when it forced a Michigan coal-fired power plant to stay open past its scheduled retirement date last year.

The energy secretary, Chris Wright, had said the 64-year-old JH Campbell Generating plant was needed to ensure reliable electricity in the region, and he used emergency powers to keep it operating. Environmental groups and three states – Michigan, Illinois and Minnesota – went to court to try to overturn orders keeping the plant online.
