[quick news] on February 3, 2019, UNESCO celebrated the birth of the periodic table of chemical elements

UNESCO celebrates the birth of the periodic table of chemical elements UNESCO launched the "International Year of the periodic table of chemical elements" in Paris on the 29th A series of theme activities will be held this year to commemorate the 150th anniversary of the preparation of the periodic table of chemical elements by Russian scientist Mendeleev UNESCO launched a new education project "1001 inventions: journey from alchemy to chemistry" at the launch ceremony on the same day The project will provide schools around the world with teaching materials and scientific experiment programs to enhance young people's understanding of chemistry and its applications On December 20, 2017, the general assembly of the United Nations designated 2019 as the International Year of periodic table of chemical elements This year, a series of commemorative activities include online knowledge competition and relevant international seminars Http:// multi target toxin therapy brings hope to cure cancer According to the report of International Cancer Research Institute, there are about 18.1 million newly diagnosed cancer cases every year in the world, and cancer has become the second largest cause of death after cardiovascular disease Recently, the Israeli research team has brought good news to cancer patients: they may have found a cure for cancer for the first time - multiple target toxin (mutato) therapy The treatment uses a combination of several cancer targeting peptides and a strong peptide toxin that specifically kills cancer cells to ensure that the treatment is not affected by mutations In addition, the peptide part of multi-target toxin therapy is very small (12 amino acids long), and not rigid structure, which can enter the places that other macromolecules cannot reach Https:// blood test can diagnose fetal genetic diseases in early pregnancy American scientists have developed a new test method, which can diagnose fetal genetic diseases in early pregnancy by sequencing a small amount of fetal DNA in mother's blood The new test is aimed at 30 genes related to dominant genetic diseases Pregnant women can be tested for this genetic disease if the ultrasound shows that the fetal skeleton is abnormal or the father is relatively old If the test is positive, the pregnant woman will undergo a more invasive test to confirm the diagnosis If the test is negative, ideally, both parents need genetic counseling to better manage pregnancy All test results and follow-up tests in the study confirmed that this preliminary test for mother's blood was correct Https:// new mechanism to improve the sensitivity of infrared detector has been greatly limited in the application of infrared imaging, especially in the civil field due to its high price, low sensitivity and poor integration Recently, a new detection mechanism, ballistic avalanche, has been proposed and implemented in the two-dimensional material vertical heterojunction by Wang Xiaomu, Shi Yi and Miao Feng from the school of Electronic Science and engineering, Nanjing University Based on this mechanism, an infrared detection device has been developed This achievement not only promotes the development of high sensitive detection technology from mid infrared to single photon, but also provides a new possibility for the development of Nano Electronics in post Moore era, which is of great value for the development of new generation optoelectronic and microelectronic devices in the future The new technology of http://digitalpaper.stdaily.com/http_ Div=-1 enables autopilot to detect AI "blind spots" in driving At present, the automatic driving vehicle is still prone to make mistakes, partly because AI training can only solve some problems encountered during the driving process Microsoft and MIT have developed a model that captures "blind spots," a technology that allows AI to compare human behavior in specific situations with what a machine would have done, and change the behavior of a machine based on how well it matches For example, an autopilot does not know how to deal with an ambulance on the road AI can learn and imitate by observing the driving behavior of the surrounding car The model can also be modified in real time, and if the AI is out of control, the human driver can take over and correct the problem https://www engadget .com/2019/01/27/microsoft-and-mit-ai-blind-spots/
