In 2019, the Nobel Prize in physiology or medicine was announced, and the "cell sensing oxygen pathway" won the title at 17:30 on October 7, 2019 Beijing time In 2019, the Nobel Prize in physiology or medicine was announced, and the winners were William g kaelin Jr, Peter J Ratcliffe and Gregg L Semenza The reason for the award was that "they discovered how cells perceive and adapt to oxygen supply" William g kaelin Jr., an American physician and professor of medicine at Harvard University, is committed to studying the role of p53 and other tumor suppressor genes in the development of cancer He won the Lasker prize for basic medical research in 2016 Peter J Ratcliffe, British cell and molecular biologist, clinician, head of Clinical Medicine Department of Oxford University, mainly studies cell response under hypoxia, and won the Lasker prize for basic medical research in 2016 Gregg L Semenza, a professor at Johns Hopkins University School of medicine, found that HIF-1, which adapts cancer cells to hypoxia, won the Lasker prize for basic medical research in 2016 Https://www.nobelprize.org/prices/medicine/2019/summary/ "immunodrugs + targeted drugs" strong combination of advanced lung cancer control rate of 100% Recently, at the world lung cancer conference, Shanghai Chest Hospital released two research results of new domestic lung cancer drugs, which significantly improved the efficacy compared with the traditional treatment methods After the results were published, it triggered strong repercussions, marking the breakthrough of China's independent innovation of anti-cancer drugs Relevant leading experts said that in the near future, we will further expand the scope of clinical research and strive to benefit more patients as soon as possible The two studies were led by Professor Han Baohui, director of respiratory department of Chest Hospital, on "the efficacy and safety of cindilimab combined with androtinib as the first-line treatment for advanced non-small cell lung cancer", and Professor Lu Shun, director of Oncology Department of Chest Hospital, led by "the third generation of EGFR-TKI ometinib, the first / second generation of egfrtki, the first-generation new drug in China" Application in the treatment of advanced non-small cell lung cancer patients after drug resistance Two research results of domestic immune and targeted drugs not only mean better therapeutic effect, but also can reduce the economic burden for countless patients suffering from advanced lung cancer Http://dzb.whb.cn/2019-10-07/7/detail-654822.html new forms of matter help speed up quantum computing According to the recent report of the organization network of physicists, American physicists have found a new form of matter topological superconductive state This breakthrough is expected to improve the storage capacity of electronic devices and enhance the capacity of quantum computing Quantum computing is a much faster method than traditional methods The traditional computer processes digital bits in the form of 0 and 1, while the quantum bits of the quantum computer can be any value between 0 and 1 or even the superposition of both, so it can improve the data processing ability and speed in an exponential way In the new study, the team analyzed the transition of quantum state from traditional state to a new topological state, measured the energy barrier between these States, and directly measured the characteristics of the transition The newly discovered topological superconducting state on the two-dimensional platform paves the way for the construction of scalable topological quantum bits, which can not only store quantum information, but also manipulate the quantum state without errors Http://digitalpaper.stdaily.com/http_www.kjrb.com/kjrb/html/2019-08/19/content_.htm? Div = - 1 the team of HKUST revealed the mechanism by which cyanobacteria were killed by the virus, helping to slow down global warming A team from the Hong Kong University of science and technology recently revealed the mechanism by which green bacteria, cyanobacteria, are killed by a virus called phytophagosome The new discovery is expected to improve the ability of cyanobacteria to absorb carbon dioxide, which will help slow down global warming in the future More than 20% of the earth's carbon dioxide is absorbed by cyanobacteria, which carry out photosynthesis in the ocean to provide oxygen for marine organisms, according to researchers at HKUST However, nearly half of the world's cyanobacteria die every day due to predation or virus infection Among them, phagocytosis virus kills about one fifth of the world's total cyanobacteria every day The research team led by Zeng Qinglu, an associate professor in the Department of marine science at the University of science and technology, spent five years studying the phytophagosome cultured in the laboratory The results showed that the energy produced by photosynthesis of cyanobacteria became the fuel for the phagosome to infect cyanobacteria, which made the phagosome complete all the infection processes that could destroy the cell structure of cyanobacteria in the daytime, leading to the breakdown of cyanobacteria at night This is the first time scientists have found that the virus has a circadian rhythm Http://www.xinhuanet.com/tech/2019-10/06/c_.htm luminescent nanoparticles control beating of heart cells fluorescent materials will release photons when excited by external photons Generally, the energy of the light emitted is lower than that of the excitation light, but the photons emitted by the materials called the conversion fluorescent materials are larger than those excited by them However, the material proved to be difficult to manufacture The team at the National University of Singapore has developed a converted nanoparticles that emit red or green light depending on the wavelength of infrared radiation used to excite them The team invented nanoparticles that are easy to produce They are composed of an erbium rich nucleus surrounded by layers of materials rich in ytterbium and neodymium The outer layer can capture the incoming energy and transmit it to erbium rich nuclei The wavelength of the incident light determines the exact path of the energy, which determines whether the red or green light is emitted by erbium The team uses the particles to control the beating of heart cells, which adjust to different colors: red light slows the beating of heart cells, green light makes it faster http://news.sciencenet.cn/sbhtmlnews/2019/10/349989.shtm
