Trump announces an energy truce that neither Russia nor Ukraine confirms, and diesel passes $6

World

Donald Trump blamed the Russia-Ukraine war for most of the rise in US diesel prices, while analysts said the war with Iran did more of the damage. Syria's government raised the price of diesel by 40%, and people blocked roads in protest.

The world's main oil price rose as much as 5% on Monday, to $109.80 a barrel. Buyers are paying far more for oil they can have now than for oil delivered in the coming months.

Food

US diesel averaged $6.05 a gallon on Friday, in the middle of the corn and soybean harvest. Farmers are paying more just to bring the crop in.

Climate

A barrel of oil has gone from about $72 in February to over $100. China is likely to reach its goal of 70% electric car sales early, because high oil prices are pushing buyers to switch.

Dario Amodei, head of the AI company Anthropic, wrote that AI should get more capable more slowly. The heads of OpenAI and Google DeepMind backed him within hours.

An index of US chipmaker shares fell 5.9% after the bosses of big AI companies called for slower development.

Tech

Anthropic did not let Britain's government testers check its newest model before release, the Financial Times reported. Microsoft wrote rules for the AI models it builds, and named no outside body to check them.

Biotech

The US health department is backing projects in which AI programs diagnose patients and prescribe treatment. Some of its own officials worry there is too little evidence that this is safe.

Mind & body

Blocking small arteries in the knee eased pain no more than a fake procedure after 12 months. A fresh look at a major trial for glaucoma, an eye disease that slowly blinds, found its benefit vanished once every eye was counted.

Biotech

AstraZeneca, a big drugmaker, tested its new breast cancer pill added to a common drug. It did not hold the cancer back significantly longer than the usual pair of drugs.
