● On the 27th, the "3.21" China Eastern Airlines Flight Accident National Emergency Response Command held the eighth press conference, zhu Tao, director of the Civil Aviation Safety Office of the Civil Aviation Administration, said that at about 9:20 a.m. on the 27th, fire rescue personnel searched deeply in the key area designated by the technical group, manually excavated an orange cylindrical object, and the civil aviation accident investigators who investigated the scene confirmed that it was the second black box (flight data recorder storage unit) of the "3.21" China Eastern Airlines flight accident passenger aircraft. After inspection, the other parts of the logger were seriously damaged, and the appearance of the data storage unit was relatively intact. At present, the recorder has been sent to a professional laboratory for decoding work. (Source: Xinhua News Agency)

●Recently, the Zou Changling research group of academician Guo Guangcan of the University of Science and Technology of China combined the independently designed magnetic field chip with the grating chip to realize the cold atom magneto-optical well system based on the dual chip. The results are published online in the Applied Physics Review. (Source: Science and Technology Daily)
●A few days ago, Li Chuanfeng, Xu Jinshi, Sun Kai and others from the team of academician Guo Guangcan of the University of Science and Technology of China conducted experimental research on the relationship structure of multibody quantum guidance, and for the first time observed the non-monogamous sharing relationship of multibody quantum guidance, that is, the quantum state of one party can be guided by the other two at the same time. The results of the study were published in Physical Review Letters. (Source: Science and Technology Daily)

●On the 25th, "Natural And Computational Science" published the new results of Yan Gang's team on autonomous reasoning of complex systems in the School of Physical Science and Engineering of Tongji University and the Shanghai Autonomous Intelligent Unmanned System Science Center online. In this study, the author proposes a new framework for autonomous reasoning of data-driven complex systems, which realizes robust reasoning under the scenarios of incomplete structural information and strong noise, and provides an important foundation and algorithm support for the automatic and intelligent discovery of the underlying principles of real complex systems. In particular, it is worth mentioning that this algorithm can effectively verify the early transmission behavior of global infectious diseases such as SARS. (Source: China Science Daily)

Affected by abnormally high temperatures, an ice shelf in the Antarctic region recently collapsed, an area similar to the U.S. city of Los Angeles. According to CNN reported on the 25th, the Conger Ice Shelf in the east of the Antarctic region, about 1200 square kilometers, collapsed around the 15th. Rob Rattle, a marine geophysicist at the British Antarctic Mission, said warming increased the likelihood of ice shelf disintegration. (Source: Xinhua News Agency)

● On the 26th, the Philippine Volcano seismic research institute said that the Taal Volcano, located about 60 kilometers south of the capital Manila, erupted a small-scale steam in the morning, and the relevant warning level has been raised to three. The warning level for volcanic eruptions in the Philippines is divided into five levels from low to high, and three levels mean that the volcano "may erupt within weeks or days.".
