[quick news] on January 17, 2020, scientists developed "living brick"

Scientists have developed "living bricks" Now researchers have made a kind of biological concrete, and as long as the correct information is input, one brick can become two, two into four, four into eight Although the new material will not be able to build self-assembled houses in a short period of time, it may soon be able to make components that can be repaired after damage The "live" concrete could even provide a way for astronauts on their way to Mars to build houses with local materials and dangerous microbes Http://news.scienceet.cn/htmlnews/2020/1/434920.shtm liver can live 7 days without human body! This is the latest technology breakthrough, during which it can also repair the injury The perfusion machine newly developed by Zurich University Hospital uses the latest cardiopulmonary bypass technology to make the human liver leave the body for another seven days! Not only for seven days, the damaged liver can also be repaired The research is published in the Nature journal The research project is liver4life, funded by the Zurich Institute in Switzerland The researchers were from the University of Zurich hospital, the Federal Institute of technology and the University of Zurich The project was launched in 2015 and initially the liver could only survive on the machine for 12 hours Https:// scientists have found that Ginkgo biloba is a gymnosperms, often referred to as living fossil, which is the only existing species of gymnosperms, Ginkgo biloba The research team of Yangzhou University found that the plant tissue of Ginkgo biloba can grow continuously for hundreds or even thousands of years Chinese scientists analyzed the cambium of Ginkgo biloba (i.e the tissue containing meristem cells, which can ensure plant growth and ring formation), determined the level and activity of genes related to disease resistance and transcription factors involved in cell death Http://sputniknews.cn/science/202001161030467605/mathematical model can predict the success or failure of antibiotic therapy A team of Israeli biophysicists and doctors has said they have developed a mathematical model that can predict the success or failure of certain antibiotic therapies, so as to help doctors accurately select antibiotics for patients' conditions and improve the cure rate and survival rate of patients The research was published recently in the journal Science In the long run, Balaban believes that studying the development and evolution of antibiotic tolerance and drug resistance of bacteria may play a role in cancer treatment and be used to guide cancer treatment Http://digitalpaper.stdaily.com/http_ HTM? Div = - 1 the new neutron semiconductor detector can be put into the pocket US researchers recently published a research report in the journal Nature, saying that they have developed a small neutron semiconductor detector that can be put into the pocket by using a new lithium rich semiconducting material This detector is highly efficient and stable It can be used as a portable device for on-site inspection, or as a super large detection device It is expected to become a new generation of neutron detector The researchers point out that small neutron detectors have great application space in various fields Their research results will stimulate scientists' interest in the research of neutron semiconductor detector, and make it possible for the semiconductor detector to replace the 3He proportional counter http://digitalpaper.stdaily.com/http_
