Here’s today’s big science story – many versions of it are out there; this from Mark Henderson in The Times is one I like:
Human genome more variable than previously thought
Superimposed profiles of different human genomes reveal the magnitude of differences – green segments
showing DNA gains, red areas representing losses, and yellow portions indicating no difference.

From the page: “A revolutionary map that compared the genomes of 270 people has shown that humans are not 99.9 per cent genetically identical as assumed, but that much more of our DNA varies between one person and the next*.”
I’ll tidy up this post later!
* About 99.5% similarity between two random people’s DNA
