[quick news] the latest natural index annual list on June 21, 2019: 17 Chinese institutions have entered the top 100, and CAS ranks first in the world

The latest annual list of natural index: 17 Chinese institutions are among the top 100 According to the 2019 annual list of natural index released recently by the Chinese Academy of Sciences, the United States, China and Germany are ranked in the top three countries, while the Chinese Academy of Sciences, Harvard University and the German Max Planck Institute are ranked in the top three 43 American institutions and 17 Chinese institutions are among the top 100 in the world According to the nature index, only China and Australia in the top 10 countries achieved positive growth in scientific research output according to the adjusted 2018 score measurement Among them, ten leading scientific research institutions in China are: Chinese Academy of Sciences (No.1), Peking University (No.10), Tsinghua University (No.13), Nanjing University (No.15), China University of science and Technology (No.17), University of Chinese Academy of Sciences (No.24), Zhejiang University (No.27), Fudan University (No.34), Shanghai Jiaotong University (No.41), Nankai University (No 51 ）。
Https:// new regulations for the first doctor of University of science and technology of China A new rule has recently been set up in the optical engineering doctoral program of University of science and technology of China: starting from the doctoral students who enter this year, they must send a Chinese article or thesis to graduate, even if they send a popular science article or even a science and technology news report in the media or magazine, but you can't do without it No matter how many good English papers you send out, you can't Han Zhengfu, Professor of the Key Laboratory of quantum information, Chinese Academy of Sciences, University of science and technology of China, said that they didn't make this decision on the spur of the moment, but because "the Chinese writing ability of current college students, especially science and engineering students, is really poor Some students may be better at English, but Chinese articles are too cumbersome, there are too many wrong words, and some even write a debit note, which is hard to see."

Div = - 1 Australia's latest research: looking down at the screen causes bone spurs on the human skull base Australian researchers found that many people are used to looking down at electronic devices such as mobile phones and tablet computers for a long time, resulting in bone spurs on the skull base Bone spur is also called hyperosteogeny Researchers have found that more and more people are now experiencing an increase in external occipital protrusion at the base of their skull as a result of looking down at their cell phones for a long time So they analyzed head scans of more than 1000 subjects aged 18 to 86 The researchers found that this type of hyperosteogeny was most common in people between the ages of 18 and 30, compared to older people The researchers say that the increase in the number of people with extra occipital protrusion at the base of the skull is related to the long time of looking down at the screen in modern people An adult's head weighs an average of about five kilograms Looking down at the screen will make the previously less used neck muscles bear more pressure In order to support the head, the muscles will become larger and stronger, which will further stimulate the expansion of the occipital external bulge of the skull base Https://baijiahao.baidu.com/s?

She said the team was working with relevant companies to bring the technology to market https://
