Answer the question at the end by quoting:

Sean John Combs was born on November 4, 1969 in Manhattan's Harlem neighborhood in New York City, and was raised in Mount Vernon, New York. His mother, Janice (Smalls), was a model and teacher's assistant, and his father, Melvin Earl Combs, served in the U.S. Air Force and was an associate of convicted New York drug dealer Frank Lucas. At age 33, Melvin was shot to death while sitting in his car on Central Park West, when Combs was 2 years old. Combs graduated from the Roman Catholic Mount Saint Michael Academy in 1987.
In 1998, Combs started a clothing line, Sean John. It was nominated for the Council of Fashion Designers of America (CFDA) award for Menswear Designer of the Year in 2000, and won in 2004. California billionaire Ronald Burkle invested $100 million into the company in 2003. Also in 2003, the National Labor Committee revealed that factories producing the clothing in Honduras were violating Honduran labor laws. Among the accusations were that workers were subjected to body searches and involuntary pregnancy tests. Bathrooms were locked and access tightly controlled. Employees were forced to work overtime and were paid sweatshop wages. Charles Kernaghan of the National Labor Committee told The New York Times that "Sean Puff Daddy obviously has a lot of clout, he can literally do a lot overnight to help these workers." Combs responded with an extensive investigation, telling reporters "I'm as pro-worker as they get". On February 14, 2004, Kernaghan announced that improvements had been implemented at the factory, including adding air conditioning and water purification systems, firing the most abusive supervisors, and allowing the formation of a labor union. In late 2006, the department store Macy's removed Sean John jackets from their shelves when they discovered that the clothing was made using raccoon dog fur. Combs had not known the jackets were made with dog fur, but as soon as he was alerted, he had production stopped. In November 2008, Combs added a men's perfume called "I Am King" to the Sean John brand. The fragrance, dedicated to Barack Obama, Muhammad Ali, and Martin Luther King, featured model Bar Refaeli in its advertisements. In early 2016, Sean John introduced the brand's GIRLS collection.

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.

What did she discover in her studies?
