IOWA CITY, Iowa (AP) — Responding to a major case of research misconduct, federal prosecutors are taking a rare step by filing charges against a scientist after he admitted falsifying data while researching an HIV vaccine.

Authorities say former Iowa State University laboratory manager Dong-Pyou Han has confessed to manipulating data that helped his team get millions in grants and increased hopes of a major breakthrough in AIDS research.

Experts say the misconduct was particularly brazen, and charges are rare in part because less money is usually involved. The National Institutes of Health is reviewing the case’s impact on research it funds.

Han resigned from the university last fall. He was indicted last week and could face prison time if convicted. He’s free on bond but didn’t respond to a message seeking comment Tuesday.

YORK, Neb. (AP) — A September trial has been scheduled for a man accused of having a sexual relationship with an inmate at the women’s prison in York.

Michael Weichman, of Bradshaw, pleaded not guilty on Monday to a charge of sexually assaulting an inmate. The 47-year-old Weichman was a staff maintenance employee at the prison. He resigned last month.

Investigators say another inmate tipped prison officials that Weichman and the other inmate were having sex. Under Nebraska law, any prison or jail worker who has sex with an inmate has committed sexual assault.

A court document says Weichman described his relationship with the inmate as playful but not sexual. She’d been assigned to do maintenance work while serving time for child abuse resulting in death.
