Recently, the National Development and Reform Commission officially issued the 2023 central budget investment plan, supporting the first batch of more than 100 small and medium-sized cities in 11 provinces in the central and western regions and northeast regions, and accelerating the construction of infrastructure networks such as 5G and gigabit optical networks.
●On the 23rd, the construction and commissioning of the new Xiamen North Railway Station skylight with a construction area of about 1,400 square meters was successful, marking the completion of the largest intelligent skylight in China's high-speed railway station.
△According to the past weather calculation in Xiamen, after the smart skylight is put into use, Xiamen North Railway Station is expected to save about 40 days of ventilation system operation per year, which is equivalent to reducing carbon dioxide emissions by 14.13 tons per year.
●The provincial government approved the construction of five provincial-level high-tech industrial development zones, namely Huaibin High-tech Industrial Development Zone, Zhoukou Huaiyang High-tech Industrial Development Zone, Suixian High-tech Industrial Development Zone, Kaifeng Fine Chemical High-tech Industrial Development Zone, and Qixian High-tech Industrial Development Zone. Up to now, the total number of high-tech zones in our province has increased to 44. Among them, there are 9 state-level high-tech zones, ranking second in the central region and fifth in the country; There are 35 provincial-level high-tech zones, achieving full coverage in 17 provincial-level municipalities and Jiyuan urban-rural integration demonstration zones.

●[Scientists grow electrodes in living tissue for the first time] The line between biology and technology is blurring. Researchers at Sweden's Linköping University, Lund University and the University of Gothenburg have successfully grown electrodes in living tissue for the first time using human molecules as triggers. The findings, published in the latest issue of Science, pave the way for the formation of fully integrated electronic circuits in living organisms.
Most female mammals decline in fertility with age, but naked mole rats can maintain fertility throughout their lives. In a new study, American scientists have revealed the unique process of such superfertility and reproductive longevity of naked mole rats, which is expected to improve human infertility research. The research was published in the 21st issue of Nature Communications.
Researchers in Japan and the United Kingdom interviewed 65 artificial intelligence experts and predicted that robots would take on nearly 40% of household chores in 10 years. Researchers said in a research report published in the American journal "Science Public Library General" on the 22nd that experts generally believe that after 10 years, about 39% of housework will be completed by automated processes. With the assistance of robots or artificial intelligence, people's time to buy daily necessities may be shortened by nearly 60%, house cleaning will be reduced by 46%, and caring for pets can save nearly one-third of time. However, only 28% of caregiving tasks, such as education, accompanying children, and caring for the elderly, can be automated.
In a new preclinical study, American scientists demonstrated that even moderate drinking accelerates brain atrophy and increases the number of amyloid plaques. The study was published in the latest issue of the journal Neurobiology of Disease.
●[Webb telescope's first data reveals massive galaxy group] early in the history of the universe or there are stars with hundreds of billions of solar masses, a paper published in the British journal Nature on the 22nd, reported the candidate massive galaxy group formed about 500 million to 700 million years after the Big Bang.
【What?! Allergic rhinitis may affect children's growth and development】 We all know that children's growth and development are closely related to genetics, nutrition, sleep, psychology, sports and other factors, but many parents may not know that allergic rhinitis may also affect children's growth and development, such as affecting children's height, weight, intellectual development, brain development, etc.
