As the iconic striped bass population declines, the AP set out to produce a national story on what could be considered a niche subject. Combining deep
China’s chemogenetic therapy trial cuts seizures in epileps…
For people living with refractory epilepsy, the brain is like a city that can suffer a blackout any time lightning strikes. Without warning, an abnormal neural discharge can sweep through the intracranial circuits, leaving behind convulsions, loss of consciousness and years of lingering panic. Around one-third of epilepsy patients worldwide are completely unresponsive to existing medications, while traditional craniotomy resection surgery often carries the risk of irreversible neurological...
Beijing approves giant Long March 9 rocket for deep-space a…
Beijing has given the go-ahead for the Long March 9, a super heavy rocket often seen as China’s answer to SpaceX’s Starship, weeks after the American megarocket first reached orbit, according to a lecture slide circulating online. The stainless-steel giant received official approval last month, according to the slide. At 110 metres (361 feet) tall and 10.6 metres wide, it will be the most powerful and expensive launcher China has ever built. The slide, presented in the northwestern city of Xian...

Chinese space firm builds wooden rocket nose cone for cheap…
Chinese commercial space firm Light Year Explorer has manufactured a rocket fairing with a wooden outer skin as part of the company’s push for lower-cost, mass-produced launch vehicles. The design of the protective shell uses low-density plywood formed into a smooth aerodynamic curve, supported by an internal metal framework to bear loads, according to the Jiangsu-based company. “This configuration matches traditional composite fairings in key performance areas such as weight, structural...
Chinese scientists chill atoms to record low on Tiangong sp…
Chinese scientists have chilled atoms aboard the Tiangong space station to the lowest temperature ever measured, smashing US and German records and paving the way for ultra-precise space sensors that could find hidden minerals, track climate change and test Einstein’s theory of gravity. Researchers from Peking University and the Chinese Academy of Sciences brought thousands of rubidium atoms, packed into a cloud smaller than a grain of sand, to less than 10 trillionths of a degree above absolute...

Lithuania builds world’s biggest ultra-fast laser factory a…
Amid tensions with China, a small European country is anchoring itself at the centre of the global semiconductor and artificial intelligence (AI) hardware supply chain as a laser powerhouse. The latest sign of Lithuania’s growing footprint in the sector came last month, when laser maker Litilit launched a new factory in the capital, Vilnius. The company’s expansion unfolds as the Baltic nation of fewer than 3 million people navigates fraught ties with Beijing, which has targeted Lithuania with a...
China performs world-first precision laser-cutting experime…
China’s space scientists have become the first to carry out precision laser cutting in orbit, slicing a piece of “large-scale equipment” with a robotic arm fixed to the outside the Tiangong space station. The official Science and Technology Daily reported on Wednesday that millimetre-scale cuts were made by a laser maintenance device operated remotely from “hundreds of kilometres away”. Precision laser cutting involves focusing a beam of light to slice or melt material with extreme accuracy, a...
Chinese scientists make toothbrush that uses electric shock…
No matter how thoroughly you brush your teeth in the morning and evening, the battle against bacteria is almost certain to be lost. Within a few hours of brushing, it will return in force and rebuild a solid defence line on the surface of your teeth. From ancient times to now, humanity has essentially had only one way of dealing with it, whether it was using twigs and sticks or the first bristled toothbrushes, which date back to 10th century China. But even today’s most advanced electric brushes...
