    According to the latest nature index, "2018 nature index - focus on China", the supplement of nature published on December 13, China's most powerful chemical industry, China's contribution to the nature index increased by 75% from 2012 to 2017, significantly exceeding that of many leading countries, such as the United States, Germany, the United Kingdom and Japan China's share of global scientific research output in the natural index also rose from 9% to 16% According to the natural index, chemistry is the most powerful discipline in China, and one-half of all natural index papers in China involve chemistry From 2012 to 2017, China's output of chemical papers in the natural index increased by 84%, ranking the second in the world and behind the United States A series of monographic articles have been published in this issue to analyze China's scientific research performance and leading position in such advantageous fields as chemistry, plant biology, astronomy and space science, biomedical engineering and nanoscience Https:// "nature" calls for the ethical consideration of the relevant research on human stem cell-derived embryo model In the laboratory, the use of stem cells to make mouse and human embryo model is developing rapidly At the same time, it also brings profound legal and ethical issues In view of this, the British journal Nature recently published a review article, calling on the international community to discuss, pointing out the direction for this fast-growing research field In this paper, scientists have raised several issues that need to be discussed publicly, including whether the embryo like entities in the laboratory should be regarded as human embryos now or in the future, and how to set the limits for cultivating complete human embryos They urged funding agencies and scientific and medical communities to take the lead in discussions There has been a huge debate on whether to regard embryoid bodies as human embryos Some scholars believe that although human embryos have the potential to develop into complete human beings, there is still a difference between human beings with potential and those who actually exist However, the opposite view holds that human embryos should be regarded as having the ability to develop into adults from the beginning of fertilization Https:// China's innovation index has reached a new high recently According to the 2017 China innovation index calculation results released by the National Bureau of statistics, China's innovation index in 2017 was 196.3, an increase of 6.8% over the previous year, a new high since 2005 2017 was a fruitful year for China's innovation output, with an innovation output index of 236.5, ranking first in four sub sectors, up 13.2 points or 5.9% over the previous year In 2017, the number of patent applications and authorizations in China was 1.721 million, an increase of 5.6% over the previous year, including 327000 invention patents, an increase of 8.2% over the previous year 1.7 million scientific and technological papers were published throughout the year, an increase of 3.0% At the same time, China's technology market is also developing rapidly In 2017, the contract value of China's technology market was 1342.42 billion yuan, an increase of 17.7% over the previous year Http://finance.people.com.cn/n1/2018/1213/c1004-30463005.html Heilongjiang Science and technology award applicants won the first prize of natural science with one paper on December 13, and the results of 2018 Heilongjiang Science and technology award were newly published The most outstanding highlight is that the project "molecular mechanism of HIV Vif 'hijacking' human CBF β and cul5e3 ligase complex" undertaken by Professor Huang Zhiwei's team of Harbin University of technology won the first prize of natural science of Heilongjiang Province When submitting the evaluation materials, the project only submitted one high-quality paper published in the journal Nature, and submitted eight representative papers as required Professor Huang Zhiwei, who was brought back from Harvard University, became the first scientific researcher in Heilongjiang history to win the first prize of natural science of Heilongjiang Province with one paper He has also become the first person to benefit from Heilongjiang's new principle of "not only quantity, but also quality" This is a significant breakthrough in the history of science and technology awards in Heilongjiang Province Http://digitalpaper.stdaily.com/http_ HTM? Div = - 1 In the past five years, scientists have invented sunscreen smart tattoos, and wearable technology has developed rapidly Scientists have developed a permanent tattoo ink that is sensitive to ultraviolet light and appears only when the skin is overexposed to the sun Once the sunscreen is reapplied, it will disappear immediately Many research projects regard bioengineered tattoo ink as the future of "wearable" health technology Among the researches on smart tattoos, some claim to detect cancer, while others claim to reduce blood sugar Tattoo designers are also optimizing tattoo ink to make it a diagnostic tool to help doctors identify diseases or changes in blood composition Scientists hope that one day smart tattoos will help doctors diagnose diseases https://
