The landmark  success of Tu Youyou, the first Chinese woman to win a Nobel prize in science, has aroused great national pride  and hopes on the future of traditional Chinese medicine (TCM). Tu, born in 1930, shared the 2015 Nobel Prize for Physiology  or Medicine with Irish-born William Campbell and Japan's Satoshi Omura for her discoveries against malaria . She discovered Artemisinin   , a drug that has greatly reduced the death number for patients suffering from malaria. "Artemisinin is a gift for the world people from the traditional Chinese medicine. It is of great importance for curing malaria and other diseases and for protecting the health of the world people," Tu said in Beijing. " The discovery of Artemisinin is a successful example of collective research on traditional Chinese medicine. The prize winning is an honor for China's science cause  and traditional Chinese medicine." "Tu's winning the Nobel Prize shows China's great progress in science and technology. It also shows China's growing strength and rising international standing," Premier Li Keqiang said in a letter Monday evening. How old was Tu Youyou when she won the Nobel Prize?
