Granted $100,000 for ground-breaking study

BEIJING - The idea sounds not so complicated: make a virus in a lab that could kill HIV, the cause of the deadly AIDS, to finally cure the currently incurable disease that is a major killer worldwide.

That, surprisingly, helped Liu Chang, a 28-year-old instructor at the medical school of the Tianjin-based Nankai University, distinguish himself from more than 2,000 applicants worldwide to land a $100,000 research grant in the fourth round of the Grand Challenges Explorations.
