Chinese scientists say they can create a ‘storm eye' for PLA forces in electronic warfare

This groundbreaking innovation could allow
Chinese military forces to disable enemy communications and navigation systems while protecting their own troops and allied networks from collateral disruption.
The
technology , still at an early stage with feasibility verified in computer simulations, relies on coordinated unstaffed aerial platforms that emit precisely-tuned radio frequency (RF) interference.
By adjusting the waveform, amplitude, phase and relative timing of their signals, these drones can generate a targeted null at friendly positions where jamming signals are cancelled out.
'Under the simulation condition of a 20 dB interference-to-signal ratio, electromagnetic interference at the target legitimate user can be reduced to zero,' wrote the team led by Yang Jian, a professor at the Beijing Institute of Technology, in a peer-reviewed paper published in Chinese journal Acta Electronica Sinica on July 24.

This dual capability – jamming adversaries while safeguarding allies – marks a significant evolution from traditional electronic warfare, which often relies on brute force. This usually comes in the form of omnidirectional jamming that disrupts everything within range, friend or foe, according to Yang and his collaborators from the National Key Laboratory of Wireless Communications in Chengdu, Sichuan.

Hong Kong can lead charge for yuan alternative to US stablecoin
Last month, the United States passed the Genius Act , a landmark piece of legislation that finally brings stablecoin – a cryptocurrency asset pegged to the US dollar – under a federal regulatory framework. While this may seem like a domestic achievement, the global implications are far-reaching, particularly for jurisdictions in Asia, including Hong Kong and mainland China. The Genius Act is more than just cryptocurrency regulation; it represents a digital extension of US financial influence. By legally defining stablecoins used in payment as non-securities and assigning oversight to banking regulators rather than securities regulators, the act clears the path for stablecoins like Tether and USDC to flourish globally. These tokens already dominate over 90 per cent of the stablecoin market and are set to become a default payment rail for digital transactions worldwide, especially in regions underserved by traditional banking systems. Dollar-backed stablecoins are not just technical tools; they function as a new layer of financial infrastructure. In areas with high inflation or currency instability – such as parts of Latin America or Africa – users increasingly prefer holding Tether or USDC over local currency. In decentralised finance (DeFi) and Web3 ecosystems, dollar stablecoins are the dominant medium of exchange. Even in sanctioned jurisdictions, the US government can exert influence by regulating issuers like Circle and Tether, providing Washington with a new lever of financial statecraft.

Should you use AI to plan trips? Why it doesn't mean a better holiday
By Catherine Thorbecke On a recent trip to Taiwan, I turned to ChatGPT to ask for recommendations for the best beef noodles in my area – with the very specific request that the shop had to accept credit cards, as I was running low on local currency. The chatbot immediately recommended a place that was a short walk and featured some of the most delicious, melt-in-your-mouth beef tendon I have ever had. I was pleased to be the only foreigner in the no-frills, no-air-conditioning joint that was home to a fat, orange cat taking a nap under one of the metal stools. But after my meal, I panicked when the impatient woman behind the counter had to put aside the dumplings she was folding to try and communicate in English to me that it was cash only. Even a quick Google search of the hole in the wall would have saved me from this fate, and I felt foolish for blindly trusting the AI's outputs.

In US-China battle over rare earths, developing nations are the front line
Rare earths are needed for everything from consumer electronics to electric vehicles, wind turbines and fighter jets – and China controls the supply chain. In a four-part series, we look at the race for rare earths, starting with the contest for reserves in developing countries. Former Chinese leader Deng Xiaoping once said that 'the Middle East has oil, China has rare earths'. His words carry new weight today as China's stranglehold over the rare earths supply chain gives it leverage in the trade war with the United States. China controls some 60 per cent of global mining of rare earths, over 85 per cent of their processing, and more than 90 per cent of permanent magnet production – used in everything from cars to medical devices and wind turbines. That leaves the US and other Western nations vulnerable, and many are now scrambling to diversify their supply chains away from China. Analysts say that while there are multilateral efforts under way to reduce reliance on China they are largely diplomatic, and there is a lack of investment or technical expertise to move away from Chinese supply. They also say that developing countries with rare earths are emerging as the new front line of a high-stakes contest between China and the West.
