American logistics expert reports from China video: Top Chinese scientists leave the US sinking ship in huge numbers flee Boston area as Harvard, MIT fall in rankings ; Silicon Valley also impact. 美國物流專家在中國視訊報導：中國頂尖科學家離開美國這條沉船大批逃離波士頓地區，哈佛、麻省理工學院排名下滑；矽谷也受影響.

Thousands of Chinese researchers and scientists are leaving top jobs in leading US universities and companies, to take posts 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.
