Global Technology – April 2014

Next, let's focus on this month's most important advances in technology, starting with a significant breakthrough in tissue engineering.

The ability to govern the movement of a mass of living cells has great utility as a scientific tool.  Instead of manipulating one cell at a time, researchers could develop a few simple design rules that would provide a global cue to control a collection of cells.

As documented recently in the journal Nature Materials, researchers at UC Berkeley have discovered that an electrical curren.....
