...Harrison’s breakthrough is the similarity between HIV and SIV, or simian immunodeficiency virus, and “noticing that this particular construct derived from SIV is stable” enough to yield crystals, whereas “standard HIV constructs are not stable,” said Harrison...
...face of it, therefore, Monday’s decision by the U.N. Economic and Social Council to approve America’s uncontested reentry onto the human rights commission seems reassuring. Sichan Siv, U.S. ambassador to the Economic and Social Council, commented that he was “very pleased” at the outcome. “Human rights,” he said, “is a cornerstone of U.S. foreign policy...
...fatal bounce enabled Hawk sophomore Anika Michaels to score the game-winning goal in the 87th minute. Hartford forward Siv Skard dribbled by two Crimson defenders and blasted the ball by Crimson goalie Cheryl Gunther, striking the post. The ball then took a Hawk bounce, ricocheting into the possession of Michaels. She put it by Gunther, who had made 3 saves on the day, for the game winner...
...colleagues, including Feng Gao, husband George Shaw and Paul Sharp, set about amplifying, sequencing and analyzing Marilyn's virus. Except in the rarest cases, chimps like the sooty mangabeys never show AIDS-like symptoms. Even so, when the researchers compared the viral DNA with the three known types of SIV (simian immunodeficiency virus), they found it had a substantially different genetic makeup. And when they compared Marilyn's genetic makeup with that of other chimps, they determined that she belonged to a different subspecies than the chimps that harbor the other SIV strains; those kindred chimps live farther east...
...what do these findings have to say about people? Exact correlations are impossible to make. SIV and HIV, although similar in many respects, are different viruses. And the scientists did not try to create the tiny tears in the lining of the rectum like those that are produced during anal sex and that increase the chance of HIV infection in humans. But generally speaking, the results support the idea that the number of HIV particles found in an infected man's semen--though not in the saliva--is sufficient to be passed on through the mouth or throat. One likely...
