Week Three, Day One
Mar. 14th, 2006 10:52 pmIt was good to get my blood moving after sitting at my computer all day, but now I'm unusually tired. Don't think I'll be staying up til 1 a.m. or thereabouts tonight.
I read a squib on Instapundit today that reminded me--again--that I'm living in the future. Allow me to quote:
Nanotechnology has restored the sight of blind rodents, a new study shows.
Scientists mimicked the effect of a traumatic brain injury by severing the optical nerve tract in hamsters, causing the animals to lose vision.
After injecting the hamsters with a solution containing nanoparticles, the nerves re-grew and sight returned.
The researchers injected the blind hamsters at the site of their injury with a solution containing synthetically made peptides - miniscule molecules measuring just five nanometres long.
Once inside the hamster's brain, the peptides spontaneously arranged into a scaffold-like criss-cross of nanofibres, which bridged the gap between the severed nerves.
The scientists discovered that brain tissue in the hamsters knitted together across the molecular scaffold, while also preventing scar tissue from forming.
Importantly, the newly formed brain tissue enabled the brain nerves to re-grow, restoring vision in the injured hamsters.
That is just too cool for words. Now if they'll just get busy on anti-aging drugs. I'm not getting any younger here, you know.
But still no flying cars, dammit.
