Arrest of professors exposes graft in academia

The arrest of four professors has raised public concern over corruption in China's scientific research system.

The four were arrested for misappropriation of State research funds through false research projects, the anti-corruption watchdog said on Friday.

Li Ning, a professor at the Chinese University of Agriculture and member of the elite Chinese Academy of Engineering, is among them. Li is noted for trans-gene research and was the first in China to clone a rare cattle species in 2002.
