The wonderful world of epigenetics
Genes are the instructions that tell our cells what to do, but how do different types of cells know which genes to switch on or off at the right time? The solution lies in epigenetics - the molecular bells and whistles that act on top of our DNA to control gene activity. Plus, a new gene involved in severe obesity, and a mythical gene of the month.

More people are starting to talk about epigenetics, but what's it all about? To find out I spoke to Robin Allshire from Edinburgh University
Researchers at Imperial College have tracked down a new gene involved in severe obesity and type 2 diabetes. Alex Blakemore tells the story.
People who inherit the same versions of certain genes from mum and dad, are shorter and do less well at school. Peter Joshi explains more.
Researchers are finding more and more roles in cells for small fragments of RNA, as Cold Spring Harbor's Rob Martienssen explains.
Itís time for our mythical Gene of the Month - and this time itís Ariadne.
