There is absolutely no connection, as you imply, between the decision not to publish Professor Watson's The Double Helix at Harvard and Thomas J. Wilson's resignation as director of Harvard University Press...
Last spring, however, Pusey unexpectedly decided to get involved. He had just received outraged letters from British scientists, Francis Crick and Maurice Wilkins protesting the forthcoming publication of James D. Watson's The Double Helix, a highly personalized narrative of the discovery of the structure of DNA. Wilkins and Crick were Watson's collaborators in the Nobel Prize-winning experiments...
...historic synthesis with four off-the-shelf inert chemical compounds called nucleotides-the basic building block of the DNA molecule, which controls the hereditary characteristics of every living thing. To these they added one enzyme, DNA polymerase, that is known to promote the assembly of nucleotides into the typical helix-shaped strand that characterizes the DNA molecule, and another enzyme that closes the strand into a ring...
...pioneering work fresh in his mind, Williams flew to Manaus, Brazil, last month to fulfill a longstanding six-week commitment to serve as senior scientist aboard the Alpha Helix, a sophisticated research vessel operated by California's Scripps Institution of Oceanography. From Manaus, Williams headed the Alpha Helix upstream for the expedition's shore camp at the confluence of the Rio Negro and the Rio Branco. The Negro, at high-water level during this time of year, "looked like Chesapeake Bay," says Williams. Along the shore, trees and plants were steeped in 30 ft. of the river...
...difficult to reconstruct human life of hundreds of thousands of years ago. But the age of the dwelling has been conclusively dated from surrounding geological formations, which have been carefully studied over the past century. And corroborating evidence comes from paleontological finds, such as the presence of the Helix pareti snails, which are known to have disappeared during the Second (Mindel-Riss) Interglacial Period...
