FOOTNOTE."The central dogma says that there is faithful transcription of DNA into RNA. This challenges that idea on a much larger scale than was known". The work suggests that RNA editing is providing a previously unappreciated source of human genetic diversity that could affect, for instance, how vulnerable different people are to disease. The ability to edit RNA to produce 'new' protein-coding sequences could be widespread in human cells." https://lnkd.in/dvUcXWZ View in LinkedIn

CRYSTALIZATION ERRORS include etch plates, where the crystallization process falls short of perfection during self-construction. See this brilliant book on natural crystal formation. https://lnkd.in/dm7JCCz View in LinkedIn

ERROR MINIMIZATION IN BIOLOGY. "Savageau demand rule: Genes that are needed often in the natural environment tend to be regulated by activators, and rarely needed genes tend to be regulated by repressors; in both cases, sites are bound for most of the time, and errors are minimized. The fitness advantage of error minimization appears to be readily selectable." http://www.pnas.org/content/103/11/3999.full View in LinkedIn

ACTIVATORS AND REPRESSORS. "Biological regulation systems convert input signals into specified outputs. The same input–output relationship can generally be carried out by several different mechanisms." http://www.pnas.org/content/103/11/3999.full View in LinkedIn

EDITING ERRORS. "Instead of trying to avoid defects or work around them, it makes more sense to accept defects as part of the process and then correct them during and after the assembly process. This procedure is analogous to how nature deals with defects, and can be applied to the assembly of nanomaterials using biomolecules or biomimetic compounds." https://lnkd.in/dR5Ajf2 View in LinkedIn

DNA BRICKS. "In 2012, researchers demonstrated that synthetic DNA strands called “DNA bricks” could self-assemble into complicated three-dimensional equilibrium structures, including letters of the English alphabet and shapes with well-defined cavities and tunnels." https://lnkd.in/dE73DV6 View in LinkedIn

UNEXPECTED LEAP FORWARD. "The demonstration came as a great surprise to researchers in the field of DNA nanotechnology: the structures had formed from about 1000 different types of DNA brick, yet the general expectation was that large numbers of component types would be unable to assemble in an error-free way." https://lnkd.in/dE73DV6 View in LinkedIn

AUTONOMOUS ROBOTICS. "Modular self-reconfiguring robotic systems or self-reconfigurable modular robots are autonomous kinematic machines with variable morphology." Wrap your mind around that one. http://en.m.wikipedia.org/wiki/Self-Reconfiguring_Modular_Robotics View in LinkedIn

SELF-REPAIRING ROBOTS. "Beyond conventional actuation, sensing and control typically found in fixed-morphology robots, self-reconfiguring robots are also able to deliberately change their own shape by rearranging the connectivity of their parts, in order to adapt to new circumstances, perform new tasks, or recover from damage." http://en.m.wikipedia.org/wiki/Self-Reconfiguring_Modular_Robotics View in LinkedIn

SELF-REPLICATING ROBOTS. "Self reconfiguring robotic systems are potentially more robust and more adaptive than conventional systems. The reconfiguration ability allows a robot or a group of robots to disassemble and reassemble machines to form new morphologies that are better suitable for new tasks, such as changing from a legged robot to a snake robot and then to a rolling robot." http://en.m.wikipedia.org/wiki/Self-Reconfiguring_Modular_Robotics View in LinkedIn
