Answer the question at the end by quoting:

Crowded House are a rock band formed in Melbourne, Australia, in 1985. The founding members were New Zealander Neil Finn (vocalist, guitarist, primary songwriter) and Australians Paul Hester (drums) and Nick Seymour (bass). Later band members included Neil Finn's brother, Tim Finn, and Americans Mark Hart and Matt Sherrod. Originally active from 1985 to 1996, the band had consistent commercial and critical success in Australia and New Zealand and international chart success in two phases, beginning with their self-titled debut album, which reached number twelve on the US Album Chart in 1987 and provided the Top Ten hits
Crowded House were midway through a US tour when Paul Hester quit the band on 15 April 1994. He flew home to Melbourne to await the birth of his first child and indicated that he required more time with his family. Wally Ingram, drummer for support act Sheryl Crow, temporarily filled in until a replacement, Peter Jones (ex-Harem Scarem, Vince Jones, Kate Ceberano's Septet) was found. After the tour, the Finn Brothers released their album Finn in November 1995. In June 1996, at a press conference to announce the release of their greatest hits album Recurring Dream, Neil revealed that Crowded House were to disband. The June 1996 concerts in Europe and Canada were to be their final performances.  Recurring Dream contained four songs from each of the band's studio albums, along with three new songs. The album debuted at number one in Australia, New Zealand and the UK in July 1996. Early copies included a bonus CD of live material. The album's three new songs, which were released as singles, were "Instinct", "Not the Girl You Think You Are" and "Everything Is Good for You", which featured backing vocals from Pearl Jam's Eddie Vedder. Paul Hester returned to the band to play drums on the three new tracks.  Worried that their goodbye had been too low-key and had disregarded their home fans, the band performed the Farewell to the World concert on the steps of the Sydney Opera House on 24 November 1996, which raised funds for the Sydney Children's Hospital. The concert featured the line-up of Neil Finn, Nick Seymour, Mark Hart and Paul Hester. Tim Finn and Peter Jones both made guest appearances. Support bands on the day were Custard, Powderfinger and You Am I. The concert had one of the highest live audiences in Australian history with the crowd being estimated at between 120,000 and 250,000 people. Farewell to the World was released on VHS in December 1996. In 2007, a double CD and a DVD were issued as to commemorate the concert's tenth anniversary. The DVD featured newly recorded audio commentary by Finn, Hart and Seymour and other new bonus material.

IN: 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.

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.
