Problem: Background: The Moody Blues are an English rock band formed in Birmingham, England in 1964. They first came to prominence playing rhythm and blues music, but their second album, Days of Future Passed, which was released in 1967, was a fusion of rock with classical music and established them as pioneers in the development of art rock and progressive rock. It has been described as a "landmark" and "one of the first successful concept albums". The band became known internationally with singles including "Go Now", "Nights in White Satin", "Tuesday Afternoon", and "Question".
Context: For their next two albums, Every Good Boy Deserves Favour (1971) - from which Hayward's "The Story in Your Eyes" was taken as a US charting single (No. 23) - and Seventh Sojourn (1972) (which reached No. 1 in the US), the band returned to their signature orchestral sound which, while difficult to reproduce in concert, had become their trademark. The title "Every Good Boy Deserves Favour" was borrowed, tongue-in-cheek, from a mnemonic used to remember the musical notes that form the lines of the treble clef: EGBDF. The opening track "Procession" was the only item composed by all five band members, a fascinating track depicting the "evolution" of music, leading into Hayward's "Story in Your Eyes". Thomas's reflective "Our Guessing Game" and whimsical "Nice To Be Here" offset the deeper drama of Hayward's "You Can Never Go Home", Lodge's "One More Time To Live" and Pinder's "My Song". Edge, the long-standing drummer-poet, started writing lyrics intended to be sung, rather than verses to be spoken - his "After You Came" (1971) featured each of the four lead singers taking a vocal section. Then in 1972, Lodge's songs "Isn't Life Strange?" (No. 13) and "I'm Just a Singer (In a Rock and Roll Band)" (No. 36) were lifted from Seventh Sojourn as charting UK singles. Sojourn also saw Pinder using the new Chamberlin instrument in place of the mellotron and Edge using an electronic drum kit. Pinder's stirring lament "Lost in a Lost World" opened this last "Core Seven" outing, while his sympathetic ode to Timothy Leary "When You're a Free Man", Thomas's romantic "For My Lady", and Hayward's serene "New Horizons" all stood out. In an interview following the release of Seventh Sojourn, Graeme Edge told Rolling Stone: "We've got two Christians, one Mystic, one Pedantic and one Mess, and we all get on a treat." By this time, other bands were picking up their work. Pinder's songs "A Simple Game" (1968) and "So Deep Within You" (1969) were successfully covered by the Four Tops, Pinder winning an Ivor Novello Award for "A Simple Game", Elkie Brooks later covered Hayward's "Nights in White Satin". Pinder also appeared on John Lennon's "Imagine" album in 1971, providing additional percussion on "I Don't Wanna Be a Soldier (I Don't Want to Die)". The 1968 to 1972 album sleeves, plus several solo sets up to Ray Thomas's "Hopes, Wishes & Dreams" in 1976, were characterised by striking surreal scenic sleeve artwork (mostly gatefold sleeves) by artist Phil Travers. In late 1972, a re-issue of the five-year-old "Nights in White Satin" became the Moody Blues' biggest US hit, soaring to number two on the Billboard Hot 100 and becoming a certified million-seller; the song had "bubbled under" the Hot 100 charts on its original release. The song also returned to the UK charts, reaching No. 9, ten places higher than its original release in 1967.

Background: Henrietta Lacks (born Loretta Pleasant; August 1, 1920 - October 4, 1951) was an African-American woman whose cancer cells are the source of the HeLa cell line, the first immortalized cell line and one of the most important cell lines in medical research. An immortalized cell line will reproduce indefinitely under specific conditions, and the HeLa cell line continues to be a source of invaluable medical data to the present day. Lacks was the unwitting source of these cells from a tumor biopsied during treatment for cervical cancer at Johns Hopkins Hospital in Baltimore, Maryland, U.S., in 1951. These cells were then cultured by George Otto Gey who created the cell line known as HeLa, which is still used for medical research.
Context: George Otto Gey, the first researcher to study Lacks's cancerous cells, observed that her cells were unique in that they reproduced at a very high rate and could be kept alive long enough to allow more in-depth examination. Until then, cells cultured for laboratory studies survived for only a few days at most, which wasn't long enough to perform a variety of different tests on the same sample. Lacks's cells were the first to be observed that could be divided multiple times without dying, which is why they became known as "immortal." After Lacks' death, Gey had Mary Kubicek, his lab assistant, took further HeLa samples while Henrietta's body was at Johns Hopkins' autopsy facility. The roller-tube technique was the method used to culture the cells obtained from the samples that Kubicek collected. Gey was able to start a cell line from Lacks's sample by isolating one specific cell and repeatedly dividing it, meaning that the same cell could then be used for conducting many experiments. They became known as HeLa cells, because Gey's standard method for labeling samples was to use the first two letters of the patient's first and last names. The ability to rapidly reproduce HeLa cells in a laboratory setting has led to many important breakthroughs in biomedical research. For example, by 1954, Jonas Salk was using HeLa cells in his research to develop the polio vaccine. To test his new vaccine, the cells were mass-produced in the first-ever cell production factory. Additionally, Chester M. Southam, a leading virologist, injected HeLa cells into cancer patients, prison inmates, and healthy individuals in order to observe whether cancer could be transmitted as well as to examine if one could become immune to cancer by developing an acquired immune response. HeLa cells were in high demand and put into mass production. They were mailed to scientists around the globe for "research into cancer, AIDS, the effects of radiation and toxic substances, gene mapping, and countless other scientific pursuits". HeLa cells were the first human cells successfully cloned in 1955, and have since been used to test human sensitivity to tape, glue, cosmetics, and many other products. Since the 1950s, scientists have grown 20 tons of her cells, and there are almost 11,000 patents involving HeLa cells. In the early 1970s, a large portion of other cell cultures became contaminated by HeLa cells. As a result, members of Henrietta Lacks's family received solicitations for blood samples from researchers hoping to learn about the family's genetics in order to differentiate between HeLa cells and other cell lines. Alarmed and confused, several family members began questioning why they were receiving so many telephone calls requesting blood samples. In 1975, the family also learned through a chance dinner-party conversation that material originating in Henrietta Lacks was continuing to be used for medical research. The family had never discussed Henrietta's illness and death among themselves in the intervening years but with the increased curiosity about their mother and her genetics, they now began to ask questions.
