Here is the news.An international medical journal's retraction of 107 research papers from China, many of them by clinical doctors, has reignited concerns over academic credibility in the country. Tumor Biology, a journal published by Springer Nature, announced a couple weeks ago that it had retracted the papers after an investigation showed the peer review process had been compromised. Peter Butler, editorial director for cell biology and biochemistry at Springer Nature, said the articles were submitted with reviewer suggestions, which had real researcher names but fabricated email addresses.Butler told Shanghai-based news website The Paper that the editors thought the articles were being sent to genuine reviewers in the discipline. Following investigation and communication with the real reviewers, they confirmed they did not conduct the peer review. Peer review is an evaluation of work by one or more people of similar competence to those who produce the work, which helps validate research. The online notice about the retraction lists all 107 articles and 524 authors, nearly all of whom are clinical cancer specialists from China. The hospitals named are all top public institutions.

China's air quality monitoring network is to be expanded to cover a wider area, especially at the grassroots level, to facilitate scientific and effective control of airborne pollution. By March, more than 5,000 monitoring stations had been built across China. They are managed by the environmental monitoring authorities at four levels, namely State, provincial, city and county levels.The China National Environmental Monitoring Center operates 1,500 State-level monitoring stations nationwide. The center ensures that the data collected are independent of local government oversight to prevent interference and guaranteeing accuracy and authenticity. The 5,000-plus monitoring stations test for six "criteria" of airborne pollutants, including PM2.5, PM10 and sulfur dioxide, across different regions and locations.

For example, over the Tomb Sweeping Day holiday last month, paths at a local park became seriously clogged with bikes, while careless parking of the bikes often blocks traffic as well.The police are partnering with bike-sharing companies to monitor the number of bikes in d
