Scholar retracts paper A group led by Chinese scholar Han Chunyu has decided to retract their controversial paper about a new gene-editing technique, according to a retraction statement of the journal Nature Biotechnology released last week. Han from Hebei University of Science and Technology, and his team published a paper in Nature Biotechnology last May. In their latest statement, the authors said despite the efforts of many laboratories, an independent replication of the results in their paper has not been reported. Mayor jumps into river Li Zhonghua, mayor of Yongcheng City in Henan Province, jumped into the city’s Huchenghe River last week to test the anti-pollution efforts of local authorities. In recent years, with increasing garbage and heavy pollution, the river was silted up and the water flowed slowly, fueling a spasm of public complaints. The city took a variety of measures to strengthen the mud river bed with rocks and concrete planks and raised fish. The latest data showed the water quality has reached the national level of Grade III, suitable for aquaculture and swimming.(SD-Agencies) ? |
