[quick news] new element periodic table predicts the fate of different elements on January 30, 2019

The European Chemical Society recently released a new periodic table of elements, which shows the relatively rich or scarce reserves of 90 natural elements on the earth in a distorted way The new table points out that oxygen is the most abundant element on earth and is not in danger of disappearing; but many of the elements used to make high-tech devices such as computers and smartphones are at stake For example, indium is used to make touch screens for mobile phones and computers There are only a few places in the world that supply indium If we continue to discard old equipment every few years, indium may soon dry up In addition, the fate of helium is not optimistic Helium is the second most abundant element in the universe, but because people fly party balloons too much, helium may only last for decades on earth Https:// Tsinghua master died in the Dutch fire The local university donated money to him According to the official website of Leiden University in the Netherlands, Zhang Maolin, a graduate of Tsinghua University, died on January 17, 2019 due to a local apartment fire He was only 28 years old Zhang Maolin was born in Yangtang village, Qidong, Hunan Province in 1991 He studied at Tsinghua University for his bachelor's degree, and then obtained his master's degree from Tsinghua University In 2017, he went to Leiden University in the Netherlands to study for a doctor of astronomy under the support of the State Scholarship Council In addition, Leiden University launched an activity to help Zhang Maolin's parents To help Zhang Maolin's parents build a safe and stable future, Leiden University plans to raise 45000 euros (about 35000 yuan) to support Zhang Maolin's parents' retirement for about 10 years At present, the donation amount has reached more than 58000 euros Http://epaper.ynet.com/html/2019-01/29/content_.htm? Div = - 1 Chinese scientists build a new screening method: a drop of blood makes cancer nowhere to hide Recently, sun Jiashu, a researcher of the national nano center of Chinese Academy of Sciences, built a set of cancer screening method with high "cost-effective": only 1 microliter of serum (usually 1 / 5000 of blood taken by blood vessels) ）Through the detection of extracellular vesicles, six kinds of cancer can be screened in 20 minutes, and the cancer can be classified more accurately This method is called tumor fluid biopsy According to the research team, this technology can not only be used for the early diagnosis of some types of solid tumors, but also can monitor tumor recurrence and evaluate the efficacy It has the advantages of easy access to specimens, small trauma, non-invasive and repeated collection Https:// modify the hen gene, which can produce eggs containing human protein Researchers of Edinburgh University modified the hen gene to make the eggs contain some human protein, which has found a very cheap way to produce the protein needed by human health and treat diseases The research project, funded by the UK research and Innovation Fund (ukri), was originally aimed at finding ways to produce high-quality proteins for scientific research The researchers used a new method to code the hen's genes so that the newly produced proteins were produced as part of the egg white The researchers said the modification of the hen's genes did not have an adverse effect on her body, and she was still able to lay normally Https:// two joint laboratories established by Hong Kong Polytechnic University and Chinese Academy of Sciences The "Joint Laboratory" jointly established by the Hong Kong Polytechnic University and two research institutions under the jurisdiction of the Chinese Academy of Sciences, the Academy of mathematics and Systems Sciences and the Guangzhou Institute of geochemistry, was unveiled on the campus of the Hong Kong Polytechnic University on August 28 The two laboratories are "Institute of mathematics and systems science, Chinese Academy of Sciences - Joint Laboratory of Applied Mathematics, Hong Kong University of science and technology" and "Guangzhou Institute of geochemistry, Chinese Academy of Sciences - Joint Laboratory of environmental pollution process and control, Guangdong, Hong Kong and Macao, Hong Kong University of Technology" The two joint laboratories will cooperate with each other in expanding scientific research frontier, knowledge transfer application and talent cultivation, and contribute to the future development of Guangdong, Hong Kong, Macao and the Greater Bay area and society in the fields of Applied Mathematics and environmental protection http://
