The New Zealand Herald reports on genetic research that lays the groundwork for ambitious future medicine - regrowing lost limbs, suppressing cancers, repairing the damage caused by neurodegenerative conditions such as Parkinson's, and increasing resistance to common diseases. "Starfish can regenerate limbs. We are highly similar to starfish [compared to flies or plants]. We will come to understand aging, cancer and the regeneration of limbs." Knowledge is at the root of all modern medical progress - especially in areas like regenerative medicine, where we seek to manipulate existing cellular processes. The more we learn, the closer we come to cures for age-related conditions and the aging process itself.
