Four satellites of the BeiDou Navigation Satellite System (BDS) have recently passed tests in orbit and started operation in the network. The four satellites include the 41st, 49th, 50th and 51st satellites of the BDS family. The 50th and the 51st BDS satellites, launched on Nov. 23, 2019, are operating in medium Earth orbit, and were developed by the Innovation Academy for Microsatellites of the Chinese Academy of Sciences.
A Chinese research team has realized entanglement of two quantum memories via fibers over 50 km, making a breakthrough in the field of quantum communication. The experiment was jointly conducted by researchers with the University of Science and Technology of China (USTC), Jinan Institute of Quantum Technology, and Shanghai Institute of Microsystem and Information Technology of the Chinese Academy of Sciences.
A study showed that the compound hot extremes increase by about one day every 10 years on average during that period, and the temperature increases by 0.28 degrees centigrade every 10 years. Statistical analysis revealed that the increase is mainly caused by greenhouse gas emissions.
The oceans' great continent-wrapping currents, each one moving as much water as all the world's rivers combined, can rightly be considered the planet’s circulatory system. And this circulation, it appears, has started to thump faster: For nearly 25 years the currents have been rapidly speeding up, partly because of global warming.
Dr. Oluwarotimi Williams SAMUEL obtained a Ph.D. degree in Pattern Recognition and Intelligent Systems from the University of Chinese Academy of Sciences, Beijing in 2018 courtesy of the CAS-TWAS president's fellowship, receiving several distinguished honors and awards during the program. And this is his story in China.
Quentin Montardy, gained CAS PIFI program at 2017, and became an assistant research fellow of the Shenzhen Institutes of Advanced Technology of the Chinese Academy of Sciences. Between Europe and China, he has lots of experiences and thoughts to share with you.
Laurent Pitre is a Researcher at the French Metrology Organization LNE-CNAM since 2000. He holds a Phd in Low Temperature Thermometry - below 1 Kelvin (1999), and has started his career with the European project “Ultra Low Temperature”. He has worked for two years at the National Institute of Standards and Technology (NIST), Washington D.C. as a Guest Researcher, where he has started to conceive and develop a quasi spherical resonator applied for low temperature thermometry (2003-2005).
