Unbeknownst to patients partaking in NIH studies, 900 hundred current and former scientists at the National Institutes of Health legally collected millions in royalties for drugs and inventions they developed while working for the government, the Associated Press reported. The doctors did so legally because until recently, they were not required by NIH to disclose such information to patients. According to the AP, NIH even went so far as to block several scientists' attempts to disclose the royalty information.
