You might not have to ever charge your phone again thanks to nuclear batteries
Chinese Firm developed Nuclear Battery that can Produce Power for 50 years
This Nuclear Battery the Size of a Coin Could Change Everything. Betavolt says its battery could power mobile phones that never need to be charged and drones that can fly forever
Betavolt Technology, the Beijing-based start-up, announced the successful development of the world’s first micro-atomic energy battery. In a press conference, company CEO Zhang Wei revealed they have created an innovative new power source that combines nickel-63 isotope decay and China’s first diamond semiconductor module. This integration allows the battery to be dramatically miniaturized while maintaining low production costs

[Successful Levitation Experiment of "Low Vacuum Tube Maglev Train" by China Aerospace Science and Industry Group]
On January 29, 2024, the Third Academy of Aerospace Science and Industry of China successfully completed the full-scale superconducting electric levitation/suspension test of ultra-high-speed low-vacuum tube maglev transportation system (hereinafter referred to as "high-speed flying car") at the high-speed flying car test base in Yanggao County, Datong City, Shanxi Province.
This test uses a superconducting vehicle to achieve stable suspension on the full-scale test line. This test verifies key technologies such as coupling dynamics analysis and control of "vehicle-tube-line" complex system, stable suspension of large-mass superconducting vehicles, high-power traction drive, and whole-process safety coordinated control, breaking the maximum speed record of domestic full-scale superconducting maglev, improving the overall technical maturity of the system, and laying a solid technical foundation for the subsequent higher-speed test of high-speed vehicles and the construction of the national three-dimensional transportation network.

A massive detector in China will try to find a supernova before it happens
Astronomers don’t know the finer details of how a star explodes, but observing the processes as it starts might help give some clues.

Chinese #scientists developed a wireless minimally invasive implanted #BCI technology device and implanted it into the #brain of a 54-year-old male patient who been paralyzed for 14 years in all four limbs. Three months after the operation, the patient was able to use #brainwave activity to drive an air-powered glove and drink water independently, with a decoding accuracy rate of over 90%.
