An obvious step later in this research is to be able to transplant these photoreceptors into someone other than the donor. Additionally, taking a look at the atricle's final quote
"This technique gives us new insights in repairing damage to the retina and possibly other parts of the central nervous system,"
lends to the thought that some combination of implantation procedure, possibly along with something like anti-oxidant therapy , may be feasible therapy for rebuilding other disrupted nerve pathways as well.
Sorry, have to point out a few things, though I'll generalize just a little bit: at the cellular level, metabolism references the processing of energy which is almost wholly seperate (and outside of the nucleus) from the machinery that engages in the correction of dna replication errors. All cells die, whether it's by "old age" or apoptosis (programmed, organized cell death brought on by problems detected at checkpoints during the cell cycle--as opposed to necrosis due to an injury which we'll ignore for this discussion) and these are actually good things for the organism (us humans in this case). Replication errors happen, but our cells are VERY good at detecting and correcting it...it actually takes much more to go from an error in the cell to a cancer within a human (6 things actually): self-sufficiency in growth signals, insensitivity to anti-growth signals, evasion of the aforementioned apoptosis, unlimited replicatability, sustained angiogenesis, tissue invasion and metastasis. It is these that a potential tumor cell must overcome in order become cancer as we commonly know it.
To tie all this into TFA, they were dealing with one aspect of avoiding anti-growth signals; beating aging through this route while still keeping a lid on uncontrolled (cancerous) growth is not necessarily impossible. As for the knockout mouse model used, just look at them wrong and a tumor pops up...
Thier not hoodlums genius, i live like 20 minutes away from them. thier both straight a students with alot of computer expertise but were using thier skills in the wrong way and tried to make some illegal money off of myspace. Some people need to drop the "everyone from new york is a gangster" stereotype just like they tell us to drop the "anyone not from ny is a redneck" stereotype."

And, with that eloquent statement, how could I say any more about my edukation dollars at work here in New Yawk. Please don't bother flamebaiting by blaming upstate.
Self-mod: -1 finish making your point, stupid.
Just wanted to point out that military hardware deals are as much politics as anything else, with posturing on both sides of the aisle.
Obviously, this is not a *new* issue.

Some info for you on transgenic mouse models...

I'm not real good with ages, but I don't think the author of TFA is 16...18 maybe.

If America can so easily *switch off* the software, why should we worry about any further 3rd party transfers? google cache
