Chinese scientists say they can create a ‘storm eye' for PLA forces in electronic warfare
Chinese scientists have developed an advanced electronic warfare technique that can create a zone of electromagnetic calm, similar to the eye of a storm at the heart of an intense signal jamming environment. Advertisement 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. Advertisement 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.

Could franchise model be way forward for rugby 7s? A new club-based event hopes to find out
With the HSBC SVNS Series undergoing another change in format and some unions cutting their rugby sevens programmes entirely, the sport has been facing an uncertain future. Tom Burwell, a former executive director of the Emirates Dubai 7s with 20 years' involvement in the sport, is the driving force behind a new professional sevens tournament based on seven franchises playing over the summer that will launch in 2026. With early seasons expected to be based in Europe before going global, Burwell, who is CEO of Bia Sports Group, which owns English Premier League side Sunderland, tells Josh Ball why the franchise model is the way forward and why some of the world's best players are already signing up to take part. Sevens tournaments are typically played over three days, but yours would be four hours once a week. Are shorter events the answer? 'The sport has often been challenged to be relevant week on week. During my time in Dubai, our interest was, how do we build the most successful three days possible here in the desert, and the important role we played within what was the HSBC World Rugby Sevens Series. 'But I don't think a huge number of fans were totally dialled into what would then happen in Cape Town the following week.
