DNA-based Data Storage Here to Stay | The Scientist Magazine®

DNA-based Data Storage Here to Stay | The Scientist Magazine® | Plant health | Scoop.it
The second example of storing digital data in DNA affirms its potential as a long-term storage medium.

Researchers have done it again—encoding 5.2 million bits of digital data in strings of DNA and demonstrating the feasibility of using DNA as a long-term, data-dense storage medium for massive amounts of information. In the new study released today (January 23) in Nature, researchers encoded one color photograph, 26 seconds of Martin Luther King Jr.’s “I Have a Dream” speech, and all 154 of Shakespeare’s known sonnets into DNA.

 

The researchers calculated that 1 gram of DNA could hold more than 2 million megabytes of information, though encoding information on this scale will involve reducing the synthesis error rate even further.

Knapco's insight:

The original article is not brand new, but it is worth mentioning: N. Goldman et al., “Towards practical, high-capacity, low-maintenance information storage in synthesized DNA,” Nature, doi: 10.1038/nature.11875, 2013.

This revolutionary experiment could develop into a new option for archival data storage, wherein DNA is not thought of as a biological molecule, but as a straightforward non-living data storage medium...

Evolution in Four Dimensions - videolectures.net

Evolution in Four Dimensions - videolectures.net | Plant health | Scoop.it

Ideas about heredity and evolution are undergoing a revolutionary change. New findings in molecular biology challenge the gene-centered version of Darwinian theory according to which adaptation occurs only through natural selection of chance DNA variations. In Evolution in Four Dimensions, Eva Jablonka and Marion Lamb argue that there is more to heredity than genes. They trace four "dimensions" in evolution—four inheritance systems that play a role in evolution: genetic, epigenetic (or non-DNA cellular transmission of traits), behavioral, and symbolic (transmission through language and other forms of symbolic communication). These systems, they argue, can all provide variations on which natural selection can act. Evolution in Four Dimensions offers a richer, more complex view of evolution than the gene-based, one-dimensional view held by many today. The new synthesis advanced by Jablonka and Lamb makes clear that induced and acquired changes also play a role in evolution.

Knapco's insight:

Cellular epigenetic inheritance is explained by many cases from plant, animal and other organisms' world. Eva Jablonka and Marion Lamb argue that there is more to heredity than genes. What determines an organism are “five mothers”: the provider of DNA resources, the provider of non-DNA part of the egg (nuclear and cytoplasmatic), the provider of early nourishment (womb & milk), the provider of home and care and the provider of social education. After this lecture one can start  understanding heredity and evolution on different way, as well as how stress and food can influence generations.
