...always exciting for a biologist to find an animal species for the first time, but the 1974 discovery made by Michael Tyler of the University of Adelaide was even more fascinating than usual. Searching a boulder-strewn, fast-flowing creek in an Australian rain forest, Tyler spotted a frog unlike any he'd ever encountered. While its appearance--brown back and cream-colored underside--was nothing special, its reproductive behavior proved to be downright bizarre. The female swallowed her own eggs, incubated them in her stomach and gave birth through her mouth. A single mother coughed up 21 offspring...
...that possible? How could this amphibian, christened the Australian gastric-brooding frog, carry the eggs (and then the tadpoles) inside her stomach without having the offspring digested by stomach acid? To his amazement, Tyler found that the mother frog had the ability to turn off her stomach acids while carrying her precious cargo...
...short answer is no. The slightly longer answer is definitely not. The Jurassic Park idea--amber, insects and bits of frog DNA--would not work in a million years, and it was by far the most ingenious suggestion yet made for how to find dinosaur genes. Cloning a mammoth--flash-frozen for several thousand years--might just prove feasible one day. But dinosaurs, 65 million years...
Blind and deaf frogs everywhere - and, maybe, humans - got a piece of good news this weekend when Japanese researchers announced they had successfully grown frog eyes and ears in a Tokyo laboratory. It took the sensory organs about five days to emerge from a carefully cultivated soup of the frogs' own embryonic stem cells during the groundbreaking experiment, which may provide data that will someday allow scientists to grow sensory organs for humans. The scientists who grew the frog eyes and ears claim to be the first to have done so; this team had previously transplanted lab-grown kidneys into...
...kids eight and older have a television in their bedroom, says the Kaiser report. And a third of kids ages two to seven have TVs in their room. That's way too many kids spending way too much time alone in their bedroom with only Kermit the Frog and the offspring of Aaron Spelling to keep them company. So the first thing parents should do is take the TV out of a kid's room. Like computers, televisions should be where parents can at least tell if they are being used. Even those parents who choose not to monitor their...
