 The discovery of an 88,000-year-old human finger bone at the Al Wusta archaeological site in the Nefud Desert, Saudi Arabia, has turned this idea on its head. The age of the fossil suggests an earlier migration from Africa into Eurasia - a theory supported by other archaeological discoveries made in China that were previously met with skepticism.

 1927年 ,奥地利科学家Julius Wagner-Jauregg因发明抗疟药奎宁获得诺奖 ,这也是第一次因为药物发明而被授予诺奖。在此之前 ,有关疟疾的研究已经两次摘得诺奖 ,一次是因为发现疟原虫 ,另一次是因为发现疟原虫的作用机理。

 After the first stage, I ask them some questions about a picture with no words. They are nervous, shy and some freeze and need to be crank started or come back later. Maybe some have not talked to a foreigner and are very shy. Most didn't know the answers because they learn by rote. And they are amazing as to what they can memorise. In that confusion of question time we have to say "that's all" and some knew they were finished. But for most we had to say "bye bye" with matching hand waving for them to realise they could go. Many long goodbyes were had.

 Both sides will integrate their advantages and assets to cooperate in all areas of the logistics system, according to the announcement. They also plan to carry out further collaborations to set up a fund management platform and manage immovable assets.

 The researchers used computerized tomography - or CT - scanning to confirm the bone was human, followed by a process known as uranium series dating to narrow down its age.
