If you have a subscription to Scientific American, make sure you check out Carl Zimmer's discussion of the question "What is a species?".  It's a good introduction to a long-running conundrum in biology.  Don't expect an answer, however -- not because Carl doesn't know, but because one does not currently exist.

In one of my snarkier moments, I coined the term "Dog's Ass Plot" (DAP) in reference to

A graphical representation of data in any field that, through a lack of clear axis labels, selective inclusion/exclusion of data, visual presentation style, and/or other questionable characteristics, generates a misleading interpretation of the data in the viewer, especially by implying an illusory pattern that is not supported by the available data.

This was based on a figure that purported to demonstrate a relationship between non-coding DNA and complexity.

 

Perhaps you struggle with crafting elegant and effective prose. Fear not, gentle reader! Some simple guidelines are available to assist you.

 

HOW TO WRITE GOOD

1. Avoid alliteration. Always.

2. Prepositions are not words to end sentences with.

3. Avoid clichés like the plague.

4. Eschew ampersands & abbreviations, etc., and don’t use contractions.

5. Parenthetical remarks (however relevant) are to be avoided.

6. Remember that it is wrong to ever split an infinitive.

7. Foreign words and phrases, though en vogue, are not apropos.

8. One should never generalize.

Over on Sandwalk, Larry Moran reports on a survey revealing that about 1/4 of Canadians do not believe in God, and that among those under 25 this figure is about 1/3. What he didn't mention was the actual population sampled:

 

One copy of the human genome is more than 3 billion nucleotides in length, and weighs in at about 3.5 picograms (pg, or trillionths of a gram). Only about 1.5% of this is composed of our 20,000 or so protein-coding genes, though other data suggest that at least 5% has been conserved by natural selection, suggesting that a notable portion of the non-coding majority is also functional. On the other hand, it is now apparent that much of the genome residing in our cells is made up of sequences like transposable elements -- "parasites" of the genome that can move about wwithin and be copied independently of the "host" genome -- and especially their extinct remnants. One such element, Alu, is present in more than one million copies.

I am sure that most readers are familiar with programs like the Nobel Prize winning Doctors Without Borders (i.e., Médecins Sans Frontières) and its spin-offs. Now the New York Academy of Sciences has initiated Scientists Without Borders, which is a project aimed at "mobilizing science, improving lives".

If you're a scientist, get over there and maybe see what you can do.
