Two of the most significant science events of 2007 occurred within the space of a fortnight. The first was when scientists announced that they had been able to clone dozens of embryos from an adult monkey â?? a technical feat that had eluded researchers since the announcement on cloning Dolly the sheep back in 1997. The second breakthrough happened when researchers showed that it was possible to convert human skin cells into the equivalent of embryonic stem cells, which could then be used to make beating heart-muscle and brain cells in the test tube.
