Genetic jiggery-pokery.

It's long been known that DNA encodes information in a four-bit pattern which can be read and processed like any other bitstream. Four different nucleotides, paired two by two, arranged in one of two configurations side by side by side in a long string of letters, many times longer than the size of the cell containing the full DNA strand. Every cell in every single lifeform contains the same DNA sequence, regardless of what the cell actually does. So how, many have asked, does a cell know if it should help produce hair, or skin, or pigments, or something else …

Memristors now a viable component of electronic circuitry.

In the early 1970's an electrical component was hypothesized by Leon Chua, who was working at the University of California at Berkeley as an electrical engineer. Chua was said to be working on a mathematically rigorous foundation for the science of electronics, and during the course of his work he concluded that a fundamental component was missing. A memristor is essentially a component which remembers how much current has passed through it for a duration of time (technically, there is a relationship between the integrals over time t between current and voltage). While that doesn't seem all that interesting it …
