Fri, 08 Aug 2008 15:58:43 -0500 http://www.physorg.com/news137420024.html (PhysOrg.com) -- A cell's nucleus - home of it its most precious contents — is a delicate envelope that, without support, is barely able to withstand the forces that keep it in place. Now, researchers have discovered a network of molecules in the nuclear membrane that provide the nucleus with rigidity and also facilitate a previously undiscovered form of communication between the cell`s nucleus and its cytoplasm.
