[quick news] the first case in China on January 25, 2019: daughter transplanting mother's uterus to give birth to "Tiangong baby"

The first case in China: the mother of daughter transplantation gave birth to "Tiangong baby" recently, Yang Hua (pseudonym), the first patient in China who received human uterus transplantation, gave birth to a baby boy safely, which is the first case in China and the 14th "Tiangong baby" in the world On November 20, 2015, a team of experts from Xijing Hospital of Air Force Military Medical University successfully transplanted the mother's uterus to Yang Hua, 22-year-old daughter of "congenital absence of uterus", and helped Yang Hua form 14 frozen embryos with assisted reproductive technology On June 13, 2018, frozen embryos were implanted After 14 days, the resuscitated embryo was implanted and Yang Hua was pregnant successfully This is the fifth attempt In order to avoid the pressure of the full-term fetus on the transplanted uterus, the expert team carried out cesarean section at 33 + 6 weeks of Yang Hua's pregnancy The operation was successful and the new born baby's body indexes were normal Http://digitalpaper.stdaily.com/http_www.kjrb.com/kjrb/html/2019-01 / 24 / content_ HTM? Div = - 1 India will build aligo to detect gravitational waves India plans to start building its own LIGO (laser interference gravitational wave observatory) - Advanced LIGO (aligo), and the site has been finally approved The $177 million Observatory is expected to be completed in 2024, when it is expected to improve the sensitivity and accuracy of gravitational wave detection The head of gravitational wave science and data analysis of aligo project said that aligo will help scientists achieve three main goals: to determine the source of gravitational wave with accuracy 5-10 times higher than the existing findings; to accurately calculate the size of black holes; and to better understand the expansion speed of the universe Https://www.nature.com/articles/d41586-019-00184-z new magnetic materials show quantum spin liquid more than 40 years ago, Nobel Prize winner Philip Anderson proposed quantum spin liquid theoretically According to the theory, in quantum spin liquid, the "behavior" of magnetic moment is like that of liquid, which will not freeze even at absolute zero, thus producing some special material properties Recently, an international research team has used advanced experimental techniques such as inelastic neutron scattering and muon spectroscopy to prove that tbino 3, a perovskite related metal oxide, exhibits a quantum spin liquid state This is a form of matter that scientists have been searching for for a long time, and it is expected to be used in quantum computing and other fields Https://www.nature.com/articles/s41567-018-0407-2 The more social media is used, the more likely it is to feel lonely According to a survey published in the United States recently, excessive addiction to social media is not a good thing Negative experience of social media will increase loneliness The more social media is used, the more likely it is for users to feel lonely The causal relationship between loneliness and the negative experience of social media use is not clear, but the researchers pointed out that loneliness is a bad psychological state, which is related to diseases such as hypertension, heart disease and depression When social media is widely used, we should educate the public on how to treat and use social media, and break the vicious circle of negative experience and loneliness Https://journals.sagepub.com/doi/full/10.1177/0890117118824196 Japanese researchers developed a crosstalk robot that can say crosstalk automatically It can improvise the story and shake the burden with the help of artificial intelligence technology, and successfully brought laughter to patients in the trial performance in the hospital The crosstalk robots "Xiaoai" and "Quantai" are about 1 meter and 50 cm high respectively, which are developed by Jianan University and other institutions The crosstalk robot can analyze the audience's expression image, judge whether the audience laugh or not, and find the topic in time The researchers said they hope that cross talk robots can bring happiness to hospital patients, and expect that such robots can be more used in the field of medical care http://www.xinhuanet.com/2019-01/22/c_1124024478.htm
