Sparsity In Everything: Non-Junk DNA

Tyler Cowen, an econ professor, pretty often provides in his blog, sigthings of Markets in different areas of human endeavors. He calls that series "Market in Everything". Similarly, I really would like to start a similar series with a subject in relation to Compressive Sensing by starting a Sparsity in Everything series. Let us start this series with a good candidate: Non-Junk DNA.

Even though it looks like the numbers are decreasing, about 95% of DNA is said to be currently non-coding, i.e junk, it serves non known purpose. Only 5 percent of the DNA serves a purpose. I'd say it's sparse...for the moment.

If anybody has another example, just send it to me, I'll feature it and give proper credit as usual. In particular, the example does not need to be from your own area of research.
