What is Iran's Pickaxe Mountain? Crude oil and natural gas supplies have been disrupted worldwide by the United States-Israel war on Iran, but one energy sector appears to be cashing in - coal. This week, South Africa's thermal coal producer Thungela Resources said it had doubled its half-year profits as the war has forced more countries to buy the fuel. Mining it causes water pollution, and burning it releases enormous amounts of carbon into the atmosphere, which contributes to global warming. In recent months, several countries, especially in Asia, have reversed or delayed promises to scale back on coal production.

Is the war entering a new phase? A drone strike close to the Zaporizhzhia Nuclear Power Plant in occupied southeastern Ukraine has killed one nuclear specialist and wounded 17, according to Russian reports. Moscow asserted on Tuesday that the drone was launched by Ukraine. The security of Europe's biggest nuclear plant has provoked significant global concern amid the full-scale war on Ukraine that Russia launched in February 2022. Most of those injured by the strike were employees of the plant, according to a Telegram update by the Russian management of the nuclear facility.

Long-term borrowing costs across some of the word's biggest economies hit fresh highs because of concerns over inflation, government debt levels and spending on Artificial Intelligence (AI). The interest rate on US borrowing over 30 years hit 5.33% on Tuesday, the highest since June 2007, meanwhile UK long-term debt reached 5.85%. There were similar moves in Germany and Japan. Interest rates on bonds - which are a type of debt - are known as yields and can directly affect the borrowing costs consumers pay on mortgages, car loans and credit cards. Rising oil prices are the main driver behind this recent surge in bond yields, as investors fear inflation could spike again. If that happens, central banks may choose to raise interest rates to cool inflation.

The Download: how people really use AI, and Flock's design choices Plus: a child privacy trial starting today could change Meta forever. We still don't know how people are really using AI AI companies like Anthropic and OpenAI regularly publish reports on how people are using their products. But they only release the data they want us to see, AI researchers say, and there's no independent source to corroborate it. A new research project called the AI Observatory aims to fill in the gap. Its analysis shows many more sensitive behaviors than are captured in reports from major AI companies, which focus more on work than on personal use. The researchers also found significant differences between models.

Improving energy performance can effectively extend the time a robot can operate and reduce battery load, enabling lighter, more flexible, and more durable robotic systems. Nature has evolved optimal energy-saving locomotion strategies through billions of years of natural selection, providing unparalleled blueprints for robotic optimization. Among diverse modes of aquatic locomotion, intermittent swimming, also called bout-and-glide swimming, is a widespread adaptive behavior in aquatic organisms of a wide range of sizes, including larval zebrafish, red-nose tetra, koi carp, and even whales. This natural bout-and-glide gait features alternating motion phases: short periods of active body and tail undulation for propulsion, followed by passive gliding with a streamlined, straight body posture. It is widely recognized that this intermittent swimming gait is closely associated with optimizing biological energy, making it of great research value to transplant and explore such natural motion mechanisms into robotic control systems.
