DNA computation gets logical

From PhysOrg.com:

Biomolecular computers, made of DNA and other biological molecules, only exist today in a few specialized labs, remote from the regular computer user. Nonetheless, Tom Ran and Shai Kaplan, research students in the lab of Prof. Ehud Shapiro of the Weizmann Institute's Biological Chemistry, and Computer Science and Applied Mathematics Departments have found a way to make these microscopic computing devices 'user friendly,' even while performing complex computations and answering complicated queries.

'Nanomechanical Oscillators' Could Lead to New Class of Computers

'Nanomechanical Oscillators' Could Lead to New Class of Computers from PhysOrg.com

More than 50 years ago, a graduate student in Japan conceived the “Parametron,” an electrical circuit that could form the basis for digital computers. The concept ultimately fell flat, but recently a pair of scientists gave new life to the idea, and their work could be a first step toward a nanomechanical computer that is based on mechanical rather than electrical operations.
