Today I went to a ‘bite-sized lunchtime lecture’ at UCL, and courtesy of Dr Sara Hillman learnt that a low birth weight child was a predictor of future diabetes in the father, and that in turn having a father who smoked was a predictor of the baby being born with a low birth weight.

And then across the road at the Wellcome Trust had a look at a set of books mapping all 23 chromosomes containing the complete human DNA sequence:


There are 3 billion letters in the books, and if you compared your own DNA to the sample in the book you’d find only a few million differences
