...human life produces oxygen radicals, unstable compounds that when combined with just about anything, have toxic effects on cells. Add to that the weakening over time of the immune system, which leads the body's fight against disease, and decline is inevitable. Biologists are now experimenting on rats and rhesus monkeys to see if restricting the intake of calories (while maintaining healthy nutrient levels) will slow the metabolic rate, producing a lower body temperature that in turn will decrease oxygen consumption. A lower rate of metabolism equals fewer radicals equals longer life...
...more about the health hazards of anal sex than oral. Everybody knows, after all, that it's much easier for the virus that causes AIDS to cross the lining of the rectum than to infect someone through the mouth. Or is it? The surprising results of a study on rhesus monkeys published last week in Science not only suggest otherwise but also underscore how little scientists know about how, at the microscopic level, HIV spreads from one person to the next...
Just as four-year-olds have an insight that three-year-olds lack, chimps have an advantage over lesser primates. When Povinelli tried his experiment with rhesus macaques, the monkeys proved unable to distinguish between the human who knew where the food was and the one who didn't -- even after 600 attempts...
...Four rhesus monkeys were injected with the altered SIV and remained healthy. After two years and three months, the monkeys resisted a low dose injection of live unaltered...
...many species, particularly among mammals, homosexual-like activity is an integral part of social interaction. As any cattle rancher can attest, cows frequently mount each other. Apparently this ensures that all the females coordinate their reproductive cycles and then produce their calves at the same time. Female rhesus monkeys mount other females as a way of establishing a dominant rank in their troop's hierarchy...
