Animal internal organs, artificial skin to mobile phone These scientific breakthroughs are changing your future

Human organs are cultivated from sheep. The next form of mobile phone is artificial skin. The idea of “taking things from space” has been realized The global epidemic situation is severe, but it can not stop the pace of scientific exploration. At the 2020 Tencent science we conference held a few days ago, seven top scientists from six countries gathered online to share the latest exploration and research in various fields, from artificial skin to xenogeneic organs, from brain computer interface to the universe. < / P > < p > “in 2020, the outbreak of the new crown epidemic, in the face of difficulties, our actions will probably rewrite this era.” Dawei, chief exploration website of Tencent, said in his opening speech that cutting-edge scientific breakthroughs can help us prepare to embrace the future. Therefore, we should deeply understand the challenges facing the world, and it can further stimulate our enthusiasm to become a positive force for good. In August this year, Shen Xiangyang, chairman of Xiaobing company, predicted that in the near future, the number of human-computer interaction may reach one trillion times. As the main medium of human-computer interaction, the screen means that the larger the proportion of screen, the more interactive ports. So, what is the way out for smart phones after full screen and folding screen? ‘< / P > < p > “we put forward a bold idea a few years ago, that is, the functions of mobile phones will be integrated into the clothes we wear, the electronic devices we attach to our bodies and the electronic devices we plant in our bodies.” Professor Bao Zhenan, director of the Department of chemical engineering at Stanford University, brought the design concept and practice process of “electronic skin”. She believes that there will be a big change in the electronic industry in the future. People will communicate with electronic devices like artificial skin. < p > < p > Bao Zhenan revealed that “electronic skin” has been implanted into the body of small mice, which can exercise normally and live normally, proving that these “artificial skin” are indeed compatible with biological systems. < p > < p > in Bao’s opinion, there are still three problems to be solved when “electronic skin” is applied to people. First, the electronic materials used in “electronic skin” can no longer be rigid. They must be made as soft as skin, stretch like skin, and even self repair and biodegradable. Second, these materials need to be able to really feel different objects. Third, the signals from “artificial skin” need to be able to be combined with the human body, and the human brain should be able to process the signals from the “artificial skin”. < / P > < p > “with artificial skin, you can now make a continuous, blood pressure measuring device that can be gently attached to a small baby.” Bao hopes that disabled people with prosthetic limbs and loss of touch can perceive the world through artificial skin in this way. Nowadays, many patients with advanced organ failure need artificial or mechanical “life extension”. However, there is a serious shortage of “donated organs”, and there are also many problems such as rejection of transplanted organs. How can we solve these problems? < / P > < p > at the we conference, stem cell biologist, Professor Nakai Nakai of Stanford University and Tokyo University shared the idea of cultivating transplantable and fully functional human organs in animals. In his speech, Nakai Nakai made a hypothesis in his speech: when a patient with advanced heart failure needs heart transplantation, he can generate the patient’s induced pluripotent stem cells, and then inject them into the blastocyst of pig embryos with organ formation disorders, and then produce adult pig chimera. When the chimeric pig grows to a certain extent, the heart can be taken out for human transplantation. < / P > < p > “if the research is successful and can provide patients with autologous organs, it can save many patients’ lives or improve their quality of life, and greatly reduce medical costs.” In his speech, Mr. Nakai shared the challenge project of “xenogeneic cultivation of human organs”, trying to cultivate fully functional transplantable human organs in animals, so as to solve the problems of lack of donation and immune rejection. It is reported that in July last year, he was approved for the first time to carry out animal embryo experiments containing human cells.
