The new data from the Sick Kids and Harvard groups revealed 255 regions (comprising more than 0.1 per cent) of the genome where large chunks of DNA are present in different copy numbers between individuals. Over 50 per cent of these alterations lead to changes in gene numbers and at least 14 regions ...Independent research groups have discovered novel therapeutic targets in the battle of the bulge.

In studying the way groups of cells are patterned or arranged to form segments in the developing embryo, researchers have identified a developmental "rule" followed by centipedes and thereby helped to solve a well-known evolutionary puzzle.
