Strobel admits that his frustration with the maze of federal rules and the often lengthy EPA approval process led him to start the elm test last June. Geneticist Duane Jeffery of Brigham Young University likens Strobel's actions to Oliver North's, contending that the scientist knew the rules and pulled the idealistic stunt "in the name of service to humanity." Strobel is a recognized expert on plant pathogens who once wrote that his career choice "was brought on by a desire as a teenager to understand why the chestnut trees had died in my home state of Ohio...
Armand Hammer's memoir of his 88 tumultuous years begins near the end, with accounts of his part in 1986 negotiations to clear the way for U.S. physicians to help Chernobyl's victims, and then in freeing hostage U.S. Journalist Nicholas Daniloff and a would-be Soviet emigre, Geneticist David Goldfarb. These incidents demonstrate his unusual role as a back-channel conduit between U.S. and Soviet officials. They also reflect the pragmatic approach Hammer takes toward the Soviets, his business partners on and off since the early 1920s. Readers will search in vain for indignation about the Soviet record...
Doctors diagnose Fragile X by using a microscope to examine X chromosomes isolated from white blood cells. The defective site is often clearly visible at the end of one of the chromosome's arms. Last year a more accurate diagnostic test was devised by Geneticist W. Ted Brown, of the New York State Institute for Basic Research in Developmental Disabilities (IBR) on Staten Island. Brown's team uses a technique in which snippets of DNA taken from the X chromosomes of people suspected of having the condition are compared with snippets from their normal relatives...
...test involves comparing the DNA of blood, semen or hair roots found at the scene with the DNA of a suspect. What makes it virtually foolproof is that no two people (other than identical twins) have the same genetic characteristics. While considering this fact in 1983, Alec Jeffreys, a geneticist at the University of Leicester in England, realized it might be the basis for an important new tool in criminal investigations. Using restriction enzymes as "scissors," he cut the DNA taken from several people into segments and arranged them into patterns that somewhat resemble the bar codes found on supermarket...
...rather oblique direction. UCSD Biochemist Marlene DeLuca has been investigating for 20 years how the firefly protein -- in this case, an enzyme called luciferase -- produces light. But the process of collecting and grinding up fireflies to extract the enzyme was laborious and costly. She and Donald Helinski, a molecular geneticist, decided to isolate the luciferase gene, cloning exact copies of it and splicing it into the genetic machinery of the common bacterium E. coli. The E. coli could then massproduce luciferase by the vat. DeLuca and Helinski accomplished this task by using standard recombinant DNA techniques developed over the past...
