Genetically engineered skin substitute is designed to promote wound healing
...ed. The genetically engineered skin also has high mechanical stability and is pliable, important advantages over skins made from collagen gels, which, he said, have a consistency similar to that of gelatin and therefore are much more difficult to use. Most important, Andreadis explained, the engineered tissue...Super hearing in flies may improve hearing aid technology
...ocess sound information so accurately. "Beyond the mechanical processes of the ear drum movement, we now know how the nervous system converts movement of the eardrums into information on sound direction," says Mason. The fly's ears act essentially as an extremely small, simple and sensitive directional mi...Fly on a treadmill demonstrates super directional hearing
...es are the real champions," Hoy says, describing a mechanical linkage between the fly's closely spaced eardrums as something like a playground teeter-totter, an earlier discovery made in collaboration with postdoctoral researcher Robert and Binghamton University engineer Ronald Miles.

...umber, these cells increase in size in response to mechanical load. "You remove load from the muscle and it shrinks," Dr. McNeil said. "That's an unfortunate fact of life.

"In this case, lobsters are able to make sound without relying on hard parts, and therefore they can make sound when their exoskeleton is softened and they are most vulnerable to predation." Patek said f...Scientists track down the root of cloning problems
... The Jaenisch lab also tested whether the actual mechanical process of removing a nucleus from a cell and then transplanting it into an egg somehow causes problems for developing clones. To test this, the researchers used embryonic stem cells, which are unique in that they can give rise to an entire organism ...Device liberates quadriplegic from ventilator
