Caloric restriction (CR) has long been known to increase longevity (often dramatically) in a number of eukaryotic models, including yeast, fruit flies, nematodes, mice, and rhesus monkeys. It's also well established that protein restriction can reduce cancer incidence and/or increase longevity in many organisms, independently of calorie intake.
Research into the health effects of cannabis have yielded a mixed bag (so to speak) of results. Predictably, studies that have looked for harmful effects have found them. But there are also beneficial effects, the most surprising of which involve the ability of cannabinoids to combat cancer.
Biologists are, by and large, painfully aware of evolutionary theory's shortcomings.
Like many others, I watched the recent debate between Bill Nye and Ken Ham with a queer mixture of awe and déjà vu. Who knew that 89 years later, we'd still be litigating the Scopes trial? As someone trained in the sciences, I find it horrifying that there are college-educated people in the U.S. (and around the world) who believe the earth is 6,000 years old; and yet at the same time, I have a certain amount of discomfort, myself, with evolutionary theory—not because it demeans the nobility of man or denies the Bible, or anything of that sort, but because it's such an incomplete and unsatisfying theory on purely scientific grounds. (Many physicists feel much the same way about quantum theory.)
