Heated political rhetoric is everywhere. It sets us apart from one another and erodes what's left of civil discourse. It grinds the worthy concept of "logic" into dust. Not any more. Not when we fight back with an open source game I'm calling Logic Shrink. I'm not selling a thing. You don't need an app, a console, even a board. It's entirely your game. Play a solitary version. Play it during a get-together with your extended family. Play it with kids, especially teens. Bring it to the classroom, community center, or secret Super PAC meeting. It will entertain. Afterwards, when the lively score-keeping has ended there will be something new in the room. It may be unfamiliar at first. It's a state of being that requires no name calling, no slippery slope. It's logical thinking.

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.

"In recent years, researchers in the messy world of biology have been able to build systems that function like the clean, binary switches on computer chips-and we've covered a number of reports in this area. Unfortunately, most of these share a significant limitation: they rely on proteins from bacteria that act as switches to turn genes on and off under specific conditions. We know about only a limited number of these genetic switches, which may set a severe limit on the number of logical operations we can string together inside a cell."

VANCOUVER, British Columbia - Our digital age is all about bits, those precise ones and zeros that are the stuff of modern computer code. But a powerful new type of computer that is about to be commercially deployed by a major American military contractor is taking computing into the strange, subatomic realm of quantum mechanics. In that infinitesimal neighborhood, common sense logic no longer seems to apply. A one can be a one, or it can be a one and a zero and everything in between - all at the same time.
