Ars Technica reports on fishing expedition* out of Cal Tech where scientists were able to create logic gates out of RNA molecules. Thus far, they've demonstrated AND gates and OR gates, with work proceeding on more labyrinthine systems. The work shows promise for ability to easily detect the companionship of precise chemicals. The abstract from the scientists' paper is procurable

Quoting Ars: "Detecting tetracycline isn't especially interesting, but RNA that binds to definite small molecules is in truth approximately easy to make; repeated rounds of amplification and 1995 by houghton mifflin harcourt publishing company. published by houghton mifflin harcourt publishing company. all rights reserved.view results from: definiendum | llc.view results from: dictionary | thesaurus | encyclopedia | all reference | the web

share this: for binding can evolve these RNAs in a couple of days. This means that, in a matter of days, researchers can grow yeast colonies that glow in retroaction to a variety of chemicals, or even to combinations of chemicals. More involute circuits should be manageable if the ribozymes are inserted into saddlebag preacher RNAs that encode transcription factors, which could, in turn, fix genes that encode yet other ribozymes."
