• Thousands of Chinese researchers and scientists are leaving top jobs in leading US universities and companies, to take positions in China.
• The Cambridge area of Massachusetts is home to Harvard, MIT, and scores of leading companies, and was the number one source of returning Chinese research and engineering talent.
• In second place is the Palo Alto-Berkeley cluster, which includes Stanford, University of California, and Silicon Valley.
• The migration of top scientific and engineering talent back to China is accelerating, but began nearly a decade ago. And while the political situation between China and the United States certainly is a major motivation for many scientists to return, more important is the quality of the education systems.
• Chinese universities are now claiming the top spots across all the hard science disciplines, while American colleges are tumbling.
