From Wai Wong, Melbourne, Australia
The techniques involved in the futuristic “nose job” you imagined could have better uses than smell augmentation. Implanting programmed stem cells and reconnecting neurons could restore normal function to all sorts of organs, eliminating diabetes, paralysis, anosmia, blindness, hearing loss and more. Increased neuroplasticity could help with stroke, dementia and intellectual training. The nose job itself, however, sounds risky without the original sense of smell to fall back on. Better to leave smelling work to trained animals (15 March, p 22).
