Scientists from London's Imperial Cancer Research Fund studied DNA from four men with an abnormal set of chromosomes: each bore an XX pairing that had a small piece of Y attached to one of the chromosomes. Segments of DNA cloned from the Y fragment were compared with genetic material from a wide range of male and female mammals, from chimps to tigers. Only one segment, which contained the SRY gene, was present in all the males and absent in all the females. Working with the ICRF team, London's Medical Research Council scientists showed that XY mice, which...
...working to produce new editions of both Talmudic texts, a feat no scholar has ever attempted, and, at age 50, is well along on the monumental task. This summer his Institute for Talmudic Publications will print Volume XX of the Babylonian Talmud, the halfway point, with completion expected in 15 years. To date, nearly 1 million of the various books have been sold, and an English translation is planned. Last month the long-awaited first volume of the Steinsaltz Jerusalem Talmud was issued. The first printing sold out in a matter of days; a second appeared last week...
...find out how sexual differentiation works, Page and his team decided in 1981 to study the sex chromosomes of people who are genetically abnormal: men with two X chromosomes and women with an X and a Y. Despite the genetic reversal, the XX men and XY women, although infertile, appeared normal. The scientists showed that one X chromosome in these men always had a tiny bit of Y attached, while the women's Y chromosomes always lacked that same tiny bit. The TDF gene, they figured, must be contained in that fragment, which sometimes breaks off from...
Harvard was the big favorite in The Game. And the Crimson fell behind. But the people around me didn't care. The passed around the bottle. "Go, Harvard," I yelled at one point. My words fluttered down to row XX and got smothered on some woman's hat. After that, I remained quiet...

With parts from The Tempest, a romance, and several history plays, McKellen covers all the theatrical bases from tragedy to low comedy. He even throws in Sonnet XX, for poetic justice...
