![]() ![]() Sometimes, we call things ‘boring’ simply because they lie outside the box we are currently in.” My work in Kenya, for example, was heavily influenced by a Christian Science Monitor article I had forced myself to read 10 years earlier. “Many things that end up” being meaningful, writes social scientist Joseph Grenny, “have come from conference workshops, articles, or online videos that began as a chore and ended with an insight. ![]() In this case, he transferred green and red proteins into other proteins in the epithelial cells in the hydra's inner and outer tissue layers, both of which adjust to create the mouth each time.Ībout a year ago, I happened upon this statement about the Monitor in the Harvard Business Review – under the charming heading of “do things that don’t interest you”: The trick, however, was finding a way to watch the cells in vivo, which no one has previously been able to do.Ĭo-author Robert Steele, from UC Irvine, created transgenic hydra years ago: hydra which include some cells transferred from another species. "We can try to understand what look like very complicated processes in the living animal with relatively simple physics," lead author Eva-Maria Collins, a biophysicist at UC San Diego, said in a press release. Their research suggests that the openings are temporarily created by changing cells' size, not rearranging them, as was previously thought. Scientists at the University of California's San Diego and Irvine campuses used color-coded, transgenic proteins to help track cells around the hydras' mouth areas for the first time. Once they're done, the opening is sealed up again with a layer of tissue. ![]() The opening on their tubular bodies isn't just closed their mouths really disappear until it's time to digest dinner, which they catch with poison-barbed tentacles. But the less than one-inch creatures do have a fearsome ability that might wow even the original Hydra: each time they eat, the tiny freshwater-dwelling hydra must rip apart and sew up their own mouths. On almost any measure, the multi-headed Hydra monster of Greek mythology is more fearsome than its real-life namesake: a genus of tiny freshwater polyps that snack on shrimp and other small invertebrates. ![]()
