evidence: The chair of Harvard University’s chemistry department has been arrested for concealing his affiliation with the Wuhan University of Technology (WUT) in China – worth millions of dollars – from his university and the US government agencies that funded his work. On 28 January, the US Department of Justice charged Charles Lieber, a pioneer in nanoscience and nanoelectronics, with one count of making ‘a materially false, fictitious and fraudulent statement’. [...] ‘The charges brought by the US government against Professor Lieber are extremely serious. Harvard is cooperating with federal authorities, including the National Institutes of Health, and is conducting its own review of the alleged misconduct,’ Harvard said in a statement. On multiple occasions Lieber ‘misled Harvard regarding his associations with WUT and Thousand Talents plan’, the university added. [...] On the same day as Lieber’s arrest, Chinese national Yanqing Ye was charged with one count of visa fraud, making false statements, acting as an agent of a foreign government and conspiracy. Ye, who is actually a lieutenant in the Chinese army and is currently in China, falsely identified herself as a student on her visa application and lied about her ongoing military service, according to the US Justice Department.
