An assistant professor has resigned after coming clean about faked AIDS research.
The assistant professor has attempted to make it appear as if an AIDS vaccine currently under development was working better than expected.
An Iowa State spokesman confirmed on Monday that Assistant Professor Han resigned in October after admitting he'd added human blood components to rabbit blood to make it appear a vaccine was spurring animals to build defenses against HIV, the virus that causes AIDS.
The human blood was from people whose bodies had produced antibodies to HIV.
University Spokesman John McCarroll said the confession came about after people raised concerns about the ISU experiments. Research samples were tested and were found to have been "spiked."
The falsified results had prompted more funding for the vaccine effort after the seemingly promising results.
Han couldn't be reached for comment.
