Designer babies, the end of diseases, genetically modified humans that never age. Outrageous things that used to be science fiction are suddenly becoming reality. The only thing we know for sure is that things will change irreversibly.
It may seem that rabbits that walk with their hind legs over their head--like an acrobat walking on her hands--belong in a circus, but this breed spends almost all the time in a lab. By comparing these sauteur d’Alfort with run-of-the-mill breeds, researchers are learning what it takes to move limbs in a coordinated way. Now, they have pinned down the single genetic mutation that likely causes this peculiar form of locomotion.WATCH NOW
