[quick news] science and nature were released on April 17, 2019! Former Cambridge University scholars were investigated for data fraud

"Science" and "nature" are all removed! The former Cambridge University scholar was investigated for data fraud Recently, science and nature both withdrew a paper on DNA repair process because of data fraud It is worth noting that in these two papers, the author of the "crime" is the same The author, Abderrahmane Kaidi, was a cancer researcher at the University of Cambridge before 2013 He not only cheated the top journals and reviewers, but also because of his academic misconduct in the field of DNA repair research Information from the database dimensions shows that Kaidi's research has been cited hundreds of times Even many scientists use Kaidi's paper published in nature to understand the DNA repair process mediated by kat5 Previously, Cambridge University has completed a survey of Kaidi's research misconduct and found that it has distorted and falsified data in both papers The University said in a statement that Kaidi is fully and solely responsible for these actions, and the investigation did not find problems with its partners Http://news.scienceet.cn/htmlnews/2019/4/425304.shtm "the state of global air 2019" report released: every year, the number of people who die of air pollution exceeds that of traffic accidents, the U.S Institute of health effects is jointly funded and established by the U.S Environmental Protection Agency, industry, foundation and Development Bank, and it is an internationally authoritative air pollution health research institution Air pollution ranks fifth among all the world's health risk factors, behind diet risk, high blood pressure, smoking and high fasting blood sugar, according to its latest report "the state of global air 2019" In China, air pollution ranks fourth in the health risk factors, followed by diet risk, hypertension and smoking It's worth noting that air pollution causes more deaths than many well-known health risk factors, such as malnutrition, drinking and lack of exercise, said Aaron Cohen, chief scientist of the American Institute of health effects More people die each year from air pollution related diseases than from traffic accidents or malaria Http://digitalpaper.stdaily.com/http_www.kjrb.com/kjrb/html/2019-04/17/content_.htm? Div = - 1 the world's first all carbon electronic device with atomic precision Professor Hong Wenjing and Professor Xie Suyuan, the State Key Laboratory of solid surface physics and chemistry, Xiamen University, and the innovation platform of energy and graphene, cooperated with Colin Lambert of Lancaster University in the United Kingdom to prepare the all carbon electronic device with single fullerene as the core unit and graphene as the electrode for the first time in the world, which was realized by molecular engineering of fullerene The control of the electronic properties of the all carbon device provides a new way to break through the performance and size limits of the silicon-based electronic device and develop the all carbon electronic device The research results were published online on the 15th in the journal Nature communication This interdisciplinary cooperation has pioneered the preparation technology of all carbon electronic devices with atomic level regular structure in the world, thus pushing the carbon based electronic devices to the limit size of sub nanometer, which is of great significance for the development of all carbon electronics and is expected to develop into the core materials and devices of the next generation of carbon based chip technology Https://www.nature.com/articles/s41467-019-09793-8 Israeli researchers said 3D printing out the world's first "complete" heart, researchers from Tel Aviv University in Israel announced on the 15th that they have successfully used the patient's own tissue as raw material, 3D Printing out the world's first "complete" heart with cells, blood vessels, ventricles and atria is the first in the world They first extracted fat tissue from a patient, separated cells and extracellular matrix, and then transformed them into stem cells by means of genetic modification, allowing these stem cells to differentiate into cardiomyocytes and vascular producing cells, and then mixing these cells with the hydrogel made from extracellular matrix to form "bio ink", which was eventually loaded into 3D The printer prints Tulle Deville, a professor at Tel Aviv University who led the research project, said that in the past, researchers only succeeded in 3D printing out the "simple" heart without blood vessels, but this time they used the patient's own tissue and blood vessels to print out the "complete" heart with cells, blood vessels, ventricles and atria Http://www.xinhuanet.com/science/2019-04/17/c_.htm Chinese and foreign scientific research teams have developed "band aid" for heart repair Yang Lei, a professor of Suzhou University (now working in Hebei University of Technology), sun Ning, a professor of Fudan University, and Gao Huajian, a professor of Brown University, worked together to develop a viscoelastic self-adhesive myocardial patch for myocardial infarction treatment The results were published online in nature biomedical engineering on the 15th The team first built a finite element model of the ventricle to accurately and quantitatively describe the mechanical environment of the infarcted and non infarcted regions Next, the researchers studied what kind of mechanical constraints should be applied to the infarcted area to reconstruct its mechanical function and eliminate the mechanical differences between the two areas through numerical simulation According to the best mechanical reconstruction strategy, they developed a mechanical self-adaptive self-adhesive patch GPAP with "gel point" rheological properties This study shows the advantages of interdisciplinary cooperation in medicine, physics and materials science, reveals the mechanism of mechanical action in the treatment of myocardial infarction, and develops a kind of myocardial patch with independent intellectual property rights, which is expected to be effective in the treatment of myocardial infarction https://www.nature.com/articles/s41551-019-0380-9
