Using laboratory skills that were unheard of a generation ago, scientists have isolated, put together and manipulated genes, and have come close to creating life itself. In 1967 Stanford University's Arthur Kornberg synthesized in a test tube a single strand of DNA that was actually able to make a duplicate of itself. Kornberg's "creation" was only a copy of a virus, a coated bit of genetic material that occupies a twilight zone between the living and inanimate. But many scientists have become convinced that they may eventually be able to create functioning, living cells...
...second letter, they described that mechanism: how the DNA molecule unwinds and unzips itself right down the middle during cell division, its base pairs breaking apart at their hydrogen bonds. Then by drawing on the free-floating material surrounding them in the nucleus of the cell, the two separated strands link up with complementary base-and-strand units along their entire length, forming two exact copies of the original double helix. Thus DNA faithfully passes its genetic information on to new cells and to future generations...
Sargent painted a portrait of Belle Gardner that stirred up quite a few waves along the Charles River: Mrs. Jack was pictured with a black dress wrapped quite tightly for a Boston matron, a V-cut neckline with a single strand of pearls reiterating the circular lines of her tiny waist and a single red ruby dropping from the pearls; the portrait was not nearly as risque as others that Sargent was painting at the time, but when Jack Gardner heard the comments about the picture, he forbid its public exhibition. The gossip was that, "Sargent had painted Mrs. Gardner...
...catgut substitute, which is trade-named Dexon, chemists tested 225 synthetic compounds before they hit upon polyglycolic acid, a polymer or long-chain molecule that is chemically compatible with the human body. They spent four years taming the polymer and learning how to braid it into a multiple-strand yarn of suture size...
...deployment of musical means that suits Lennon's soul-baring mood perfectly. / Found Out ("There ain't no Jesus gonna come from the sky/ Now that I found out I know I can cry") relies for much of its effect on the simple, choked sound of a single guitar strand. Elsewhere Lennon mourns the death of his mother twelve years ago, defines love (as feeling, reaching, needing, freedom) and finally, in God, Lennon says farewell to the Beatles...
