Next-generation composites may monitor their own structural health

Carbon fiber composites—lightweight and strong—are great structural materials for automobiles, aircraft and other transportation vehicles. They consist of a polymer matrix, such as epoxy, into which reinforcing carbon ...

Calculus III for cells

Last year, researchers from the University of Pennsylvania revealed surprising insights into how cells respond to surface curvature. Specifically, they investigated how cells respond to cylindrical surfaces, which are common ...

Learning how muscle cells feel the pull of gravity

People can easily feel the presence - or absence - of gravity. Our individual cells actually may be able to sense gravity, too, and that ability could play a role in the loss of muscle that occurs when humans spend time in ...

Tetrapod nanocrystals light the way to stronger polymers

Fluorescent tetrapod nanocrystals could light the way to the future design of stronger polymer nanocomposites. A team of researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley ...
