Today is Monday, August 5, 2024, the second day of the seventh lunar month
The Hainan Provincial Science and Technology Department announced that the first batch of 16 somatic cell cloned pigs have been successfully bred through advanced cell cloning technology. This achievement marks the recovery of the white five-fingered mountain pig population, which has been hit hard by African swine fever. The birth of cloned pigs not only helps to protect rare pig breeds that are on the verge of extinction, but also provides valuable experimental materials for biomedical research.
Halfway through the Paris 2024 Olympic Games, the Chinese sports delegation has shown strong competitive strength, and the overall performance is in line with expectations. According to Zhang Xin, secretary general of the Chinese sports delegation, as of the eighth day of the Paris Olympic Games, the Chinese delegation has achieved excellent results in a number of events, winning a total of 16 gold, 12 silver and 9 bronze, with a total of 37 medals. The Chinese delegation has also made breakthroughs in basic and emerging sports, such as swimming and track and field.
The research group of Hongzhi Wang, Jinfu Nie and Bo Hong from Hefei Cancer Hospital, Chinese Academy of Sciences, together with the biobank team of Shanxi Hospital (Shanxi Cancer Hospital) of the Cancer Hospital of the Chinese Academy of Medical Sciences, has successfully developed an early non-invasive detection technology for gastric cancer based on blood cell-free DNA (cfDNA) methylation and artificial intelligence (AI) identification technology. In this study, cell-free DNA methylation immunoprecipitation and high-throughput sequencing methods were used to perform genome-wide methylation analysis of cfDNA and identify 21 methylation-specific regions of gastric cancer using a variety of AI algorithms. The clinical validation results showed that the sensitivity and specificity of the newly discovered 21 methylation regions for the early detection of gastric cancer reached 88.38% and 94.23%, respectively, bringing new hope for the early detection of gastric cancer.
Many places in the mainland ushered in extremely hot weather, and the temperature approached 44°C. According to the forecast of the meteorological department, the high temperature will last for a long time, forming an "ultra-long standby" mode, and Jiangsu, Zhejiang and Shanghai have become the key affected areas, with high temperature lasting for a long time, high intensity, and a certain degree of extremeness. Among them, Hangzhou and other places have broken the record of the highest temperature in the history of observation. In addition, parts of the north will also experience unusually high temperatures, with high temperatures in northeastern Mongolia and northwestern Heilongjiang continuing until the end of this week, and the intensity is also very strong.
A team from the Yunnan Astronomical Observatory of the Chinese Academy of Sciences (CAS) has successfully captured the "shock wave breakthrough signal" in a supernova explosion based on observations of the supernova SN 2024ggi, which is located in the NGC3621 galaxy, about 20 million light-years from Earth. Using advanced equipment such as the Lijiang 2.4-meter telescope at the Yunnan Astronomical Observatory and the 10-meter Very Large Telescope at the European Southern Observatory, the research team carried out high-frequency spectral monitoring within the first few dozen hours of the explosion and successfully captured the shock wave breakthrough signal.
Panzhihua City, Sichuan Province, took the lead in launching a childcare subsidy policy in the country. From September 1, 2024, Panzhihua City will issue childcare subsidy coupons of 200 yuan/person/month to infants and toddlers aged 0 to 3 who are enrolled in inclusive childcare institutions (including kindergartens for children aged 2 to 3) in the city. This policy aims to reduce the cost of family childcare, encourage more families to choose formal childcare services, and further promote the long-term balanced development of the population. Panzhihua City has previously taken the lead in the country to launch a childcare subsidy policy, giving eligible families a childcare subsidy of 500 yuan per month until the child is 3 years old. The introduction of the childcare subsidy policy is another important measure of Panzhihua City in optimizing the fertility policy and building a comprehensive childcare support system.
A research report on the online consumption of minors at the county level was recently released, revealing the phenomenon that minors in the county generally spend a long time online, and pointed out that the situation of borrowing names for authentication is serious. The report, released by the Beijing Juvenile Legal Aid and Research Center, conducted an in-depth survey of 1,108 juveniles in six provinces, including Hebei and Guizhou, through questionnaires and interviews. The report found that nearly half of the minors spent more than three hours a day online during the school day, and nearly 80 percent of the minors spent more than three hours a day on weekends and holidays. At the same time, the survey also shows that the popularity of the real-name system for minors in the county is extremely low, with only 23% of minors using their own information for real-name authentication, and more than half of them using their parents' information for real-name authentication.
According to the latest data released by the Ministry of Civil Affairs, the number of marriage registration pairs nationwide in the first half of 2024 will only be 3.43 million, a decrease of 498,000 pairs from the same period last year, a significant decrease. If extrapolated according to the pattern of previous years, it is expected that the number of marriage registrations in 2024 may be about 6.6 million, which will be the lowest since 1980. Demographers point out that this trend is closely related to the decline in the number of young people, the changing concept of marriage and childbearing, and economic pressures such as high housing prices and an unstable employment environment.
Shandong Museum held a special exhibition - "Remembering History - The First Sino-Japanese Naval Battle and the Underwater Archaeology of the First Sino-Japanese Shipwreck Exhibition", which exhibited more than 300 pieces (sets) of precious cultural relics of the underwater archaeology of the First Sino-Japanese Shipwreck. These cultural relics were salvaged from battleships sunk in the First Sino-Japanese War, including the wreckage of rusty battleships and the weapons and equipment used by soldiers, and they silently tell the tragic history. The curatorial idea of this exhibition is unique, pioneering the model of "revolutionary cultural relics + underwater archaeology", allowing the audience to understand the history of the First Sino-Japanese Naval War and the progress of underwater archaeology on the mainland in an all-round way through physical displays, pictures, videos and other forms.
