Quick Summary

Singapore has constructed the most precise atomic clock to date after a ten-year effort. The clock uses a single ion of lutetium, achieving accuracy such that it would lose one second every 260 billion years, nearly twenty times the age of the universe. This surpasses the previous record held by China's calcium-ion clock and the aluminum-ion clock developed in the United States.

Story summary

Singapore has built the most accurate atomic clock ever, which loses just one second every 260 billion years, more than 19 times longer than the age of the universe. This decade-long project surpasses previous records set by clocks from the US National Institute of Standards and Technology and a team at the Chinese Academy of Sciences in Wuhan, making it about four times as precise as both. The new clock, constructed with a single ion of lutetium, could potentially lead to a redefinition of the second, according to researchers' claims published in a recent paper.

🔮 Chinese astronomers find planets that somehow avoided death by red giant stars Study suggests the long-term fate of the solar system, including Earth, ‘may be far more complicated than predicted’, according to scientist When a star like our sun grows old, it puffs up into a red giant that can gobble up its nearest planets.
🔮 At the ceremony, Qian said he would also work on “virtual cells” – computer models that mimic real cells so scientists can test how they might respond to drugs or disease without lab experiments.
🔮 China-US astronomy team may have found possible relic of a recent ‘gold factory’ Mystery glow seen in the Milky Way could be the result of a violent collision between two orbiting neutron stars, according to scientists The violent smash spewed out atoms and a flood of neutrons, which the atoms soaked up to form some of the universe’s heaviest elements, such as gold, platinum and uranium, while the wreckage collapsed into a black hole.
🔮 According to the latest papers, the Beijing scientists also showed that two crystals grown separately kept the same time – a sign such clocks could be reliably reproduced, they said.

🔮 That made it impossible for ground controllers to intervene in real time, wrote researchers from the China Academy of Space Technology – the country’s main spacecraft manufacturer – in a paper that will be published in the Journal of Deep Space Exploration.
🔮 China uses 100,000 home-grown AI chips to build leading weather forecast system The Sugon 8,000 system can predict weather 10 days in advance, bringing the country closer to its ambitious forecasting goals China said it can now predict weather 10 days in advance at a cutting-edge resolution of 5km (3.1 miles), finer than most major systems in routine use around the world.
🔮 The project will involve partners from at least five other countries as they track the development of space weather China has started an international project to build a three-dimensional satellite network between Earth and the moon that will track solar activity and study some of the universe’s most powerful explosions.
