●Recently, the China Manned Space Engineering Office officially solicited scientific and technological experiments and application projects based on the Tianzhou series cargo spacecraft platform. This solicitation is mainly for scientific research institutes, educational institutions, enterprises, industry organizations, etc., and the deadline is January 15, 2022. This public solicitation is the first time in the history of China's manned space program that cargo spacecraft resources are open to the public. (Source: Science and Technology Daily)

●A new study published in the Proceedings of the Royal Society B on November 24 found that due to global warming, the divorce rate of albatrosses, which are loyal to monogamy, has increased. The study said that in years with higher sea temperatures, the divorce rate of albatrosses in the Falkland Islands in the South Atlantic has increased from an average of less than 4% to nearly 8%.

●Recently, the research groups of Li Chuanfeng and Liu Biheng, members of the team led by Academician Guo Guangcan of the University of Science and Technology of China, have worked together to achieve the optimal detection of high-dimensional quantum entangled states for the first time. This achievement solves the problem of detecting two-body high-dimensional entangled states, laying an important foundation for realizing various high-dimensional quantum information processes and studying basic quantum physics problems in high-dimensional systems. The relevant results were published in the internationally renowned journal Physical Review Letters. (Source: Science and Technology Daily)

●Recently, the archaeological team of Shandong University published "Analysis of Tea Remains in Tomb No. 1 of the Warring States Period in Xigang Cemetery, the Ancient City of Zhu State in Zoucheng, Shandong" in "Archaeology and Cultural Relics", officially announcing that the tea samples unearthed in the original porcelain bowl buried with the No. 1 Warring States Tomb in Xigang Cemetery were boiled (soaked) tea residues, which is the earliest known tea remains in the world. This discovery has advanced the physical evidence of the origin of the world's tea culture by at least 300 years. (Source: Science and Technology Daily)

●Recently, Gou Huiyang, a researcher at the Beijing High Pressure Science Research Center, and others synthesized a new form of diamond, Paracrystalline diamond, under high temperature and high pressure conditions, filling the missing link in the atomic arrangement scale between amorphous and crystalline structures, and providing a key to a deeper understanding of the complex structure of amorphous materials. The results were published online in the journal Nature on November 25. (Source: China Science Daily)

●A Japanese research team has developed a new type of lithium-ion battery that uses water instead of flammable organic solvent materials and nano-scale molybdenum oxides as the negative electrode. Since this battery has no risk of fire and can be charged quickly, even if it is repeatedly charged and discharged 2,000 times, the battery capacity will only decrease by less than 30%, so it is expected to be used in energy storage batteries or short-distance electric vehicles. The relevant research paper was published in the latest issue of the Proceedings of the National Academy of Sciences of the United States. (Source: Xinhua News Agency)
