"A Swiss study appears to have uncovered what anti-capitalist activists have been claiming for years -- that the global economy is controlled by a small group of deeply interconnected entities. But don't grab a pitchfork and head to the nearest Occupy protest just yet. Systems researchers say this isn't the result of an Illuminati-type global conspiracy, but rather a natural force to be expected. "Such structures are common in nature," complex systems expert George Sudihara told NewScientist."

A new biologic logic gate based on proteins can perform binary calculations, serving as the first "cellular calculator," researchers say. Various combinations of components can be arranged into circuit elements, leading to specific metabolic processes inside a cell. The setup can answer mathematical questions in a similar fashion to a computer. Bioengineers led by Martin Fussenegger at ETH Zurich built a molecular logic gate using two substances as the transistor elements: the molecule phloretin, which is used to activate nerve fibers and comes from apples, and the widely used antibiotic erythromycin. The substances work as Boolean switches.
