●Since the beginning of this year, in the special rectification of apps that infringe on user rights and interests carried out by the Ministry of Industry and Information Technology, 9 products under Tencent have violated regulations, and a total of 4 batches have been publicly reported, violating the relevant requirements for the rectification of the work style of the information and communication industry in 2021. In accordance with the relevant arrangements, the Ministry of Industry and Information Technology has taken transitional administrative guidance measures against Tencent, requiring that new apps to be released soon, as well as updated versions of existing apps, must be technically tested by the Ministry of Industry and Information Technology before they can be put on the shelves, and can be put on the shelves normally after passing the test.

●According to a paper published in the journal Nature Chemistry on the 22nd, American researchers successfully used genetically engineered bacteria to convert glucose into fatty acids, and then into olefins (a type of hydrocarbon, one of the molecules that make up gasoline). This marks new progress in scientists' research on sustainable biofuels. (Source: Science and Technology Daily)

●Recently, researchers at the University of Cambridge in the UK have developed a new soft and resilient material, 80% of which is water. It looks like soft jelly, but can withstand the weight of an elephant standing on it. When compressed, it is like a piece of super-hard, shatterproof glass; after the pressure is released, it can return to its original shape. (Source: Science and Technology Daily)

●A proof-of-concept study was published on the 23rd in the British journal Nature Communications, in which a US research team reported an advanced microbial ink made from genetically modified E. coli that can be used to print 3D materials with functional and programmable properties. The study also demonstrated the potential applications of this technology, such as isolating toxic chemicals such as bisphenol A that appear in the environment.

●A planetary science research paper was recently published in Nature Communications. Researchers used seismic data collected by NASA's InSight Mars exploration mission to analyze and obtain subsurface images of the Elysium Planitia at a depth of about 200 meters. It can be seen that there is a shallow sedimentary layer between the lava flows. The results of this study will enhance our understanding of the geological history of Mars.
