Premium Content The WHO investigation team has visited the Wuhan wet market at the heart of the first coronavirus outbreak. The market is the site of one of the first reported clusters of infections that emerged over a year ago. Members of the group of experts arrived at Huanan seafood market - which has been sealed since January last year - driving into its barricaded premises as guards quickly blocked others from entering, according to AFP journalists at the scene. The mission, which has been delayed and heavily monitored by China, is under pressure to explore how the virus jumped from animals to humans.

THE Covid outbreak started in China in October 2019 - months before Beijing alerted the world - US scientists claim.
Researchers at the Institute for Genomics and Evolutionary Medicine at Temple University in Philadelphia also claimed that the virus definitely began in China, the Mail on Sunday reported.

Studying the creation and evolution of sulfur-containing compounds in outer space is essential for understanding interstellar chemistry. CS2 is believed to be the most important molecule in comet nuclei, interstellar dust, or ice cores. CS and S2 are the photodissociation fragments of CS2.
Forty years ago, the emission spectra of only CS and S2 species, and not those of CS2 species, were observed from several comets by the International Ultraviolet Explorer satellite. The photodissociation mechanism of CS2 molecules remains unclear, and S2 fragments have not been experimentally observed before.
Recently, a team led by Prof. YUAN Kaijun from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS), in cooperation with Prof. WANG Xing an s group from the University of Science and Technology of China, observed the C+S2 product channel from CS2 photodissociation for the first time using a home-made Time-Sliced Velocity Map Ion Imaging (TS-V
Demand for transparency in research misconduct probes
A prominent scientist and president of a prestigious university investigated by Chinese authorities for alleged data falsification has been cleared of plagiarism and research fraud, but the high-profile exoneration has attracted criticism and renewed focus on China’s policing of research misconduct.
In particular, academics have called for more transparency over the workings of such high-level ethics panels investigating prominent individuals.
Immunologist Cao Xuetao, who is president of Nankai University in the port city of Tianjin, and an academician of the Chinese Academy of Engineering, came under investigation in late 2019 when San Francisco-based microbiologist Elisabeth Bik uncovered alleged problems related to ‘misused images’ in several articles authored by Cao, and then flagged up almost 60 papers by the same author regarded as problematic.

2021 JAN 27 (NewsRx) By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News New research on Artificial Intelligence is the subject of a report. According to news originating from Wuhan, People’s Republic of China, by NewsRx correspondents, research stated, “Smart grid is the new trend for clean, sustainable, efficient and reliable energy generation, delivery and use. To ensure stable and secure operation is essential for the smart grid, which needs effective stability analysis and control.”
Financial support for this research came from National Natural Science Foundation of China (NSFC).
