●On the 15th, Hangzhou Railway Station and Hangzhou Airport announced that Hangzhou's railway and air travel policies will be adjusted from now on. In terms of railways, passengers traveling outside the province must hold a negative nucleic acid test certificate within 48 hours before they can enter the station and board the train; passengers arriving in Hangzhou from other places must provide a negative nucleic acid test report within 48 hours when entering Hangzhou. In terms of civil aviation, domestic inbound and outbound passengers at Hangzhou Airport must provide a negative nucleic acid test report within 48 hours before they can board or leave the station. Both paper and electronic reports can be used. (Source: China News Service)

●On the 15th, the Hainan Provincial Meteorological Department announced that this year's 22nd typhoon "Lei" had strengthened from a strong tropical storm to a typhoon on the morning of the 15th. At 8:00 on the 15th, its center was located on the northwest Pacific Ocean about 1,390 kilometers east-southeast of Manila, Philippines. The maximum wind force near the center was 12 (35 meters/second), the radius of the level 7 wind circle was 200 to 320 kilometers, and the radius of the level 10 wind circle was 80 kilometers.

●Recently, Ruan Changshun, Pan Haobo from the Institute of Medicine, Shenzhen Institute of Advanced Technology, Chinese Academy of Sciences, and Harbin Institute of Technology collaborated to propose a bone tissue engineering scaffold construction strategy that can be used for extrusion 3D printing to mimic natural bone tissue "cancellous bone-cortical bone" radial continuous pore regulation. The fractal theory is combined with the biomanufacturing of bone tissue engineering scaffolds to overcome the difficulty of traditional extrusion 3D printing technology in achieving radial gradient pore structure. The relevant results have been published in "Research". (Source: Shenzhen Institute of Advanced Technology, Chinese Academy of Sciences)

●Recently, the Molecular Systems Pharmacology Research Group of the State Key Laboratory of Phytochemistry and Sustainable Utilization of Western Plant Resources, Kunming Institute of Botany, Chinese Academy of Sciences, screened out functional genes significantly associated with ischemic cardiomyopathy through the transcriptional profiles of left ventricular biopsy samples from 313 patients with ischemic cardiomyopathy, using weighted gene co-expression and protein-protein interaction (PPI) network analysis. The research results have been published in the International Journal of Molecular Sciences. (Source: Kunming Institute of Botany, Chinese Academy of Sciences)
