Scientists have fabricated an artificial protein in the laboratory and examined the surprising ways living cells respond to it.

Liquid crystal research may lead to creation of new materials that can be actively controlled

Posted: 27 Dec 2012 08:08 AM PST

Contributing geometric and topological analyses of micro-materials, mathematicians aided experimental physicists by successfully explaining the observed "beautiful and complex patterns revealed" in three-dimensional liquid crystal experiments. The work is expected to lead to creation of new materials that can be actively controlled.

Evidence contradicts idea that starvation caused saber-tooth cat extinction
