Muscle Can Turn A Deaf Ear To Nerve, Study Finds
When nerves vie to be the only life-long partner of a muscle fiber, the fiber listens to one suitor, ignoring the others, which soon depart. If cells in the central nervous system behave this way, the finding could help explain how memories are soldered into the brain

NY Metropolitan Museum Of Art, Sandia National Laboratories Work Together To Preserve Statues And Infrastructure
Marble statues, the nation's bridges and tunnels, and cement blocks that entomb radioactive wastes share a common problem: limestone ingredients make them vulnerable to pitting from acid rain and spall- ing from freeze-thaw cycles that may follow. Sandia National Laboratories and the NY Metropolitan Museum of Art together are developing a coating to prolong the lives of these objects
