...Angeles District attorney's office, which prosecuted Simpson during his criminal trial. Her replacement, an Asian-American computer programmer, joins a jury that probably won't deliver a verdict any time soon. After spending 14 hours over the past three days poring over Bruno Magli photos and DNA evidence, Fujisaki has told jurors to start their deliberations again from scratch. Earlier speculation had been that Fujisaki would dismiss members over a letter sent to two jurors' homes that recommended an entertainment agent's services, but TIME's Elaine Lafferty reports the two incidents were not linked. The letter, written...
...virus out of the body in two to three years, according to Perelson's latest mathematical models. Because treatment began so early, the men's immune systems should be able to replace any lost defensive cells. There is still a chance that bits of the virus, called proviral dna, are lodged in the chromosomes, beyond the reach of even the most powerful drugs. Ho has studied these vestigial snippets of genetic information and believes they are defective and cannot give rise to a new generation of HIV. Other scientists are not so sure. The only way to find...
...looking at the structures and positions of exons and introns, Gilbert found that introns, and exons line up in a non-random way in the DNA of most living things, both primitive and modern...
Gilbert hoped to convince fellow scientists that introns--inactive DNA segments--made genes susceptible to a type of DNA recombination that randomly reshuffled exons, or active DNA segments. Gilbert believed that random reshuffling weakens the gene and lessens its chance for survival...
...phrase ignores is that basic research provides much of the knowledge for cures today. In the very same section of Time that depreciates basic research, the Telomere theory is described, a new theory of aging. This theory suggests that aging is a result of the progressive shortening of DNA within the body's cells. Now this theory could hardly be possible without the discovery of DNA itself, a result of basic research. When Francis and Crick searched for DNA, they had no idea of the possibilities ahead. However, without their discovery, bacteriophages and insertion of human genes into bacteria would...
