[quick news] China University student employment report 2019 / 6 / 14: chemistry major has become a "red card major" for employment

2019 employment report of Chinese college students: chemistry major has become a "red card specialty" for employment The 2019 employment report of Chinese college students (Blue Book of employment) lists the 2019 green card specialty and red card specialty Green card specialty refers to the specialty with small unemployment, high employment rate, salary and employment satisfaction, which is demand growth specialty Red card major refers to the major with large unemployment and low employment rate, salary and employment satisfaction In 2019, the undergraduate employment green card majors include: information security, software engineering, network engineering, Internet of things engineering, digital media technology, communication engineering, and digital media art Among them, information security, software engineering, network engineering, communication engineering and digital media art have been green cards for three consecutive times In 2019, the red card majors include painting, history, applied psychology, music performance, chemistry and law Among them, history, music performance and law were three consecutive red cards Http://edu.people.com.cn/n1/2019/0613/c1053-31134703.html is microbial resistance "drug free"? Listen to experts how to say that the news of clinical infection of Candida in the United States has attracted public attention recently, and the topic of antimicrobial drug resistance has also increased Why is microbial drug resistance frequent? Is this really going to make people "drug free"? What are the human response measures? Experts said that the decline of immunity brought about by the aging of the population led to the increase of diseases and the increase of drug resistance The spread of drug resistance was exacerbated by the reasons such as the dense population and the developed traffic network However, people's lack of awareness and the abuse of anti microbial drugs in people, livestock and poultry make this problem more prominent Experts said the use of anti microbial drugs, to avoid "children and bath water together pour out." "Not zero use, but rational use." Chen Junshi, academician of the Chinese Academy of engineering and general consultant of the national food safety risk assessment center, for example, said that to abandon the use of antibiotics to promote the growth of livestock and poultry, and to prevent livestock and poultry diseases, we should not rely on antibiotics, but need to increase investment to establish a healthy and good environment for livestock and poultry Http:// a new drug found in the United States can enhance the effect of cancer chemotherapy The latest animal experiment of American researchers found that a small molecular compound can enhance the effect of cisplatin, a cancer chemotherapy drug, and prevent the evolution of drug resistance of cancer cells Many chemotherapy drugs, including cisplatin, kill cancer cells by destroying their DNA Previous studies have found that "cross injury synthesis" is one of the main strategies for cancer cells to repair DNA damage and survive under drug attack They screened about 10000 compounds and found that this small molecular compound, jh-re-06, can interfere with "cross injury synthesis" and greatly reduce the ability of cancer cells to "resist" Cell culture experiments showed that the compound could enhance the killing effect of cisplatin on a variety of human cancer cells In animal experiments, researchers also found that mice with melanoma, a human skin cancer, had a much larger tumor reduction and a longer survival time than mice treated with cisplatin alone Affected by the compound, cancer cells that survived chemotherapy had a lower degree of mutation, the researchers said A large number of mutations are the basis for the development of drug resistance in cancer cells Inhibition of mutations can reduce the possibility of drug resistance Https:// new discovery: artemisinin is helpful for the treatment of congenital deafness The artemisinin discovered by Chinese scientists according to the literature of traditional Chinese medicine has become an "anti malaria star" In addition to treating malaria, artemisinin may also help treat congenital deafness caused by mutations in specific genes, a new study has found The researchers took zebrafish with this gene mutation as the experimental object, and found that artemisinin can help reconstruct the function of the inner ear's auditory cells It can make zebrafish produce more useful proteins in the inner ear, and help hair cells to re-establish the auditory connection Artemisinin is expected to be used to reduce deafness caused by specific genetic variation in humans and other sensory disorders caused by genetic problems in the future, the researchers said Http:// transparent film for recyclable food packaging Scientists from Oxford University have developed a completely recyclable and very safe transparent film, which can even replace the existing metal coating composite materials for food packaging The film adopts a new environmental protection manufacturing process, which is easier to recycle than the current materials used in the industry The film, made by the research team, is composed of layered double hydroxides (an inorganic material) The production process is cheap and green, and the materials needed are water and amino acids The film is transparent, which can insulate oxygen and water vapor as metal coating, and it is relatively strong As the film is synthesized, its composition is completely controllable, which greatly improves the safety of its contact with food https://
