Those facts seem to point to an environmental factor, probably the change to a Western diet. In a test of that conjecture, researchers at Sloan-Kettering, led by Dr. William Fair and pharmacologist Warren Heston, discovered that tumors grew more rapidly in mice fed a high-fat diet than in those on a low-fat diet. And when the animals on high-fat diets were switched to low-fat ones, the growth of their tumors slowed...
...less melatonin as it grows older to make extravagant claims about its antiaging properties. They write that ingesting small amounts of melatonin will allow people to turn back the clock and live 120 years or more. Their evidence? An experiment in which Pierpaoli transplanted the pineal glands of old mice into young ones, and vice versa. The glands of the younger animals seemed to rejuvenate the older ones. The younger mice who had received the old glands, by contrast, aged rapidly and died prematurely...
There's only one problem with that explanation, according to Turek. The strains of mice used in those studies do not produce melatonin. So whatever rejuvenated the aging rodents, it wasn't melatonin. "We didn't measure melatonin in the animals," Regelson concedes. "We didn't have the equipment at the time." Still, he dismisses Turek's objections, arguing, "If it isn't melatonin, what...
...BABE The three years that Chris Noonan put into directing real and animatronic dogs, mice and sheep and one adorable pig were well worth the effort. Babe is no lumbering effects movie; there's a fairy-tale soul in this machine...
...LEAN PROTEIN Researchers, knowing that a defective gene causes mice to grow fat, purified the protein produced by the normal gene, injected it into plump mice and turned them into trim little rodents. Now scientists want to know if that compound, called leptin, will work on people...
