A Chinese boycott of the “World Cup of mathematics” this year could be decisive, according to a co-organiser of a petition calling for the event to be moved out of the United States this year. Ila Varma, a University of Toronto mathematician and boycott co-organiser, said the country was “uniquely situated” to act – both as a target of US restrictions and as a major scientific powerhouse. “The Chinese government does not apply sanctions to US universities the way the US government does to...
The Process of Uranium Enrichment
Yellowstone is the world’s largest active volcanic systems – whose eruption is hundreds of times more powerful than Vesuvius’ blast and ash could blanket half the US – and yet scientists could not agree on what drives its underground magma system. But a new finding detailed by Chinese researchers could settle the dispute. They declared that Yellowstone’s magma channels were not blasted open by magma forcing its way upward. Instead, tectonic forces tore the lithosphere apart first and only then...
An international research team in China has developed a microscopic “predator-like” material capable of swimming through water and hunting uranium ions, a breakthrough that could open new possibilities for nuclear fuel extraction and cleaning up radioactive pollution. The light-powered material, a metal-organic framework (MOF) micromotor created by researchers at the Chinese Academy of Sciences’ Qinghai Institute of Salt Lakes, can autonomously move through water while capturing uranium ions....
Their study highlights how understanding nanoscale molecular behaviour can influence the design of next-generation functional materials
Chinese scientists say they have developed a wafer-scale 2D semiconductor growth method with 1,000 times faster growth, paving the way for industry advances. The surging demand for high‑performance, low‑power chips driven by AI and large-language models has intensified the search for next‑generation semiconductor technologies. Moore’s Law predicted a doubling of semiconductor capacity every two years but as chip dimensions continue to shrink, physical limitations make further performance scaling...
Scientists in Xinjiang have created the world’s first crystal that can produce the ultraviolet light needed for future thorium nuclear clocks, which could one day guide submarines and deep-space probes without GPS. The fluorinated borate compound could push laser light to a record 145.2 nanometres (nm) – a wavelength short enough to meet a key requirement for these ultra-precise, portable clocks being developed in the United States, China and elsewhere, the team reported in Advanced Materials in...

Unless material development keeps pace, integrating new materials into systems will become increasingly challenging, the DRDO chief said
Chinese researchers unveiled a gravity detector with world-leading precision last month, potentially expanding the military applications of the technology. It uses a superconducting quantum interference device (SQUID) to detect objects by measuring tiny changes in gravity. The team that developed the instrument says it can be used for scientific research and finding underground resources. It also brings the country one step closer to being able to spot patrolling nuclear submarines. According to...
Challenging six decades of convention, Chinese scientists have proposed a new composite material manufacturing method that could improve the strength and reliability of structures used in drones, aircraft and spacecraft. By introducing an advance in the so-called balanced lay-up approach – a method of stacking fibre layers symmetrically and in opposing angles to minimise internal stresses – the research team reported strength gains of up to 26 per cent. It also led to a 13 per cent improvement...
