Complex logic circuit made from bacterial genes Posted: 13 Oct 2012 02:43 PM PDT An engineer has assembled the most complex logic circuit yet assembled in a single bacterium. The logic circuit, in which genes and the molecules that turn the genes on or off function as logic gates, the simple devices that form the basis for electronic circuits, is one step in an effort to make programmable bacteria that make biofuels, degrade pollutants, or attack cancer or infections.

Scientists identify mammal model of bladder regeneration Posted: 13 Oct 2012 02:41 PM PDT While it is well known that starfish, zebrafish and salamanders can re-grow damaged limbs, scientists understand very little about the regenerative capabilities of mammals. Now, researchers report on the regenerative process that enables rats to re-grow their bladders within eight weeks.
