Highlight:“as revealed in a new paper in Science, colonies of bacteria have been converted into information-storing critters – or, to put it another way, biological hard drives…this new technique is able to encode roughly 100 bytes of data, a 73-fold increase in storage capacity…Rather than synthesizing DNA and cutting it into a living cell, the study wanted to know if it was possible to use nature’s own methods to write directly onto the genome of a bacterial cell…This way, if the bacterium replicated as it normally would, the information would be copied down through the generation. When this data is stored in a hard drive that could theoretically keep increasing in size over time, scientists could read it by examining its genome any time they wished, using any of the bacteria in the colony…”

Insight: The future of storage lies in biological systems and a good reason for that relies on the fact that we are reaching physical capacity of many materials currently in use for storage devices. This means that we can no longer (or at least not much longer) miniaturize and/or improve storage capacity due to the properties of the elements.

A recent study came up with the chocking discovery that we could store the entire human data generated to date (and that is a lot of information) in a single drop of fluid containing strands of DNA! If we put this point into the current context of the hundreds or thousands of major data centers around the world and the enormous amount of energy being used to power them, well that offers a lot of hope not just in terms of storage capacity but also sustainable development.

There is only so much that conventional technology can achieve towards improving current systems and many of them are heading towards their limits. It appears evident that natural systems are an unavoidable part of the solutions going forward in what could be seen as a fifth revolution…

What is Biomimetics: the field of gaining inspiration from nature first to solve some of our most difficult challenges. Instead of coming up with our own solutions to a problematic, the odds are that species or natural systems on the planet already offer an ultimate solution. This simple fact is also another strong case to preserve species at all cost as the intellectual heritage contained within or through the study of species is both irreplaceable and invaluable…
