Partial ageing reversal in mice http://www.physorg.com/news/2010-11-partial-reversal-aging-mice.html Although it is not quite that neat. The mice were modified not to express telomerase, so they had a form of premature ageing that doesn't quite correspond to real ageing. When they got telomerase they got better, which is somewhat unsurprising. But it is a nice building block, and telomerase control will likely be a key part of most eventual anti-ageing therapies (and perhaps cancer therapies - you don't want to overdo telomerase since then a lot of micro-cancers will not be stopped). In EP all these problems have long been solved. Any modern biomorph can be designed to be non-ageing, but I expect that for many morphs it is simply not worth the effort. They would have a long lifespan on their own, but are fully expected to be obsolete within a few years anyway. So why add all the infrastructure, occasional nanotherapies and monitoring when you just make one that lasts at least a decade with perfect health and then - who knows? Not as bad as planned obsolescence, but a bit of blade runner syndrome. The people who care about rejuvenation therapies are of course the remaining flats, people in bioconservative regimes (where they are often illegal) and the oligarchs that have a reason to keep original bodies. As an aside, here is my top 10 list of other ways of making transmice: http://www.aleph.se/andart/archives/2007/11/top_10_genetic_enhancements.... Slightly old now, but it is fun to consider how these correspond to morph enhancements. Anybody up for a brainbow menton? With diamond skull, so you can see how cool the brain looks?
