Background: Michael John Kells Fleetwood was born in Redruth, second child to John Joseph Kells Fleetwood and Bridget Maureen (nee Brereton) Fleetwood. His elder sister Susan Fleetwood, who died of cancer in 1995, became an actress. In early childhood Fleetwood and his family followed his father, a Royal Air Force fighter pilot, to Egypt. After about six years, they moved to Norway where his father was posted on a NATO deployment.
Context: In November 1977 Fleetwood and Nicks began having an affair. It would continue sporadically for the next two years during the fallout from the end of Fleetwood's relationship with Boyd, until the pair mutually decided to end the affair. "Never in a million years could you have told me that [her affair with Fleetwood] would happen," Nicks later stated. "Everybody was angry, because Mick was married to a wonderful girl and had two wonderful children. I was horrified. I loved these people. I loved his family. So it couldn't possibly work out. And it didn't. I just couldn't." Boyd and Fleetwood had in fact begun living together once more in 1976, and would remarry temporarily to assist their children with emigration to the United States. However they quickly divorced for the second time some months later. In November 1978 Fleetwood moved into a Bel Air home with Sara Recor, mutual friend of Fleetwood and Nicks who was at the time married to another music producer. Meanwhile, Fleetwood began working on a charity project to get Fleetwood Mac to tour the Soviet Union, however the Soviet War in Afghanistan later made the tour untenable.  Tusk, Fleetwood Mac's 12th studio album, was released in 1979. The work represented a more experimental direction taken by Buckingham. Fleetwood, recently diagnosed as having diabetes after suffering recurring bouts of hypoglycemia during several live shows, was again instrumental in maintaining the band's cohesion. He placated Buckingham over feelings of creative claustrophobia and discomfort playing alongside Nicks. On the issue of Buckingham taking creative control away from the other members of the group for the creation of Tusk, Fleetwood recounts that his three-day discussion with Buckingham culminated in him telling the latter that "if it's good, then go ahead." Though the nature of the album strained relationships again within the band - particularly John McVie, a long-established blues musician who disliked the experimental nature of the album - Fleetwood himself rates the album as his favourite by Fleetwood Mac, and cites the freedom of creative expression allotted to each band member as integral to the survival of the group. The album sold four million copies worldwide, a return noticeably poorer than Rumours. Though Buckingham was blamed by the record labels, Fleetwood linked the album's relative failure to the RKO radio chain playing the album in its entirety prior to release, thus allowing mass home taping.  Later that year, Fleetwood Mac embarked on a lengthy tour that brought them across America, Canada, Australia, New Zealand, Japan, France, Germany, Switzerland, Belgium, the Netherlands, and the UK. The tour lasted from October 1979 to September 1980, consisting of 113 concerts.

Background: Tu Youyou (Chinese: Tu You You ; pinyin: Tu Youyou; born 30 December 1930) is a Chinese pharmaceutical chemist and educator. She is best known for discovering artemisinin (also known as qinghaosu) and dihydroartemisinin, used to treat malaria, which has saved millions of lives.
Context: Tu Youyou carried on her work in the 1960s and 70s during China's Cultural Revolution, when scientists were denigrated as one of the nine black categories in society according to Maoist theory (or possibly that of the Gang of Four).  In 1967, during the Vietnam War, Ho Chi Minh, the leader of North Vietnam, which was at war against South Vietnam and the United States, asked Chinese Premier Zhou Enlai for help in developing a malaria treatment for his soldiers trooping down the Ho Chi Minh trail, where a majority came down with a form of malaria which is resistant to chloroquine. Because malaria was also a major cause of death in China's southern provinces including Hainan, Yunnan, Guangxi, and Guangdong, Zhou Enlai convinced Mao Zedong to set up a secret drug discovery project, named Project 523 after its starting date, 23 May 1967. Upon joining the project unit, Tu was initially sent to Hainan where she studied patients who had been infected with the disease. During the time she spent there, her husband was banished to the countryside, meaning that her daughter had to be entrusted to a nursery in Beijing.  Scientists worldwide had screened over 240,000 compounds without success. In 1969, Tu Youyou, then 39 years old, had an idea of screening Chinese herbs. She first investigated the Chinese medical classics in history, visiting practitioners of traditional Chinese medicine all over the country on her own. She gathered her findings in a notebook called A Collection of Single Practical Prescriptions for Anti-Malaria. Her notebook summarized 640 prescriptions. Her team also screened over 2,000 traditional Chinese recipes and made 380 herbal extracts, which were tested on mice.  One compound was effective, sweet wormwood (Artemisia annua), which was used for "intermittent fevers," a hallmark of malaria. As Tu also presented at the project seminar, its preparation was described in a 1,600-year-old text, in a recipe titled, "Emergency Prescriptions Kept Up One's Sleeve". At first, it didn't work, because they extracted it with traditional boiling water. Tu Youyou discovered that a low-temperature extraction process could be used to isolate an effective antimalarial substance from the plant; Tu says she was influenced by a traditional Chinese herbal medicine source, The Handbook of Prescriptions for Emergency Treatments, written in 340 by Ge Hong, which states that this herb should be steeped in cold water. This book contained the useful reference to the herb: "A handful of qinghao immersed with two litres of water, wring out the juice and drink it all." After rereading the recipe, Tu realised the hot water had already damaged the active ingredient in the plant; therefore she proposed a method using low-temperature ether to extract the effective compound instead. The animal tests showed it was completely effective in mice and monkeys.  Furthermore, Tu volunteered to be the first human subject. "As head of this research group, I had the responsibility" she said. It was safe, so she conducted successful clinical trials with human patients. Her work was published anonymously in 1977. In 1981, she presented the findings relating to artemisinin at a meeting with the World Health Organization.
