Computing has come so far in such a relatively short space of time. Beginning with comparatively basic models, which relied on arrangements of analogue circuits (such as capacitors and resistors), scientists were able to perform complex calculations, crack impenetrable cyphers, and even know how and where to deploy counter-measures against incoming missiles. And as we all know, sometimes you have to look back to the fundamentals if you want to move any farther ahead.
And that’s precisely what researchers at MIT have done with their latest innovation: an analog computer that works inside a living cell! A massive step towards a future where machinery and biology are one and the same, these “cellular computers” were not only able to perform arithmetic, but also more complex functions like taking logarithms, square roots, and even do power law scaling.
This news comes on the heels of researchers at Stanford who were able to create a biological transistor inside a cell. Relying on DNA and RNA to create a “transcriptors”, the Standford researchers were able to create a biological logic gate, and all on the microscopic scale. When combined the sorts of digital and analog circuits common to computing, this research could lead to powerful sensing and control platforms built on very small scales.
And like many recent innovations and developments made within the world of computing and biotechnology, the possibilities that this offers are startling and awesome. For one, all cells work with a certain biological clock, which regulates growth, circadian rhythms, aging, and numerous biological process. Thus far, the researchers in question have been hosting their biological computers in bacterial cells. But if they were to develop analogous circuits that operate in mammalian cells, these functions might be brought into better use.
What this means is that we could be very well seeing the beginning of biology that is enhanced and augmented by the addition of technology on the cellular level. And not in the sense of tiny machines or implants, things made of silicon and minerals that would regulate our blood flow, administer drugs or monitor or vitals. No, in this case, we would be talking about machines that are composed of self-regulating DNA and RNA and work in the same way our organic tissues do.
On top of that, we would be able to create things like flash drives and computation software from living tissue, cramming thousands of terabytes of into into a few cells worth of genetic material. Human beings would no longer need smartphones, PDAs or tablets, since they would be able to carry all the information they would ever need in their body. And the ability to do this could very well lead to the creation of AI’s that are not build, but grown, making them virtually indistinguishable from humans.
And you know what that means, don’t you? The line between biological and artificial would truly begin to dissolve, Voight-Kampff and genetic tests might have to become mandatory, and we could all be looking at robots that look something like this…
Man the future is awesome and scary!
