Air Force Treating Wounds With Lasers and Nanotech 92
An anonymous reader passes along a piece up on Wired's Danger Room about advanced medical tech that's being used in the military, but is not available generally due to the lack of FDA approval. "Forget stitches and old-school sutures. The Air Force is funding scientists who are using nanotechnology and lasers to seal up wounds at a molecular level. It might sound like Star Trek tech, but it's actually the latest in a series of ambitious Pentagon efforts to create faster, more effective methods of treating war-zone injuries. ... Instead of being sealed up with a needle and thread, a patient's wound would be coated in a dye, then exposed to green light for 2-3 minutes. The dye absorbs the light and catalyzes molecular bonds between the tissue's collagen. The bonds instantly create a seal that's watertight, which prevents inflammation or risk of infection, and speeds up the formation of scar tissue."

this sounds better than quick-clot (which is probably still the first-step treatment) in that it cauterizes and dis-infects. Qick-clot isn't a "permanent" treatment, and it doesn't replace stitches/staples/glue

There is no anti-aging pill (except maybe more Vitamin D than you're probably getting).
There is, though, an aging pill. It's called a "donut."

If you can, with the right technology, make it so that anybody who can handle a syringe full of glue, basic aseptic technique, and a flashlight can swiftly close superficial wounds, you can probably reduce the mean-time-to-treatment for the lightly to moderately wounded, reduce the number of gross, scar-tastic rushed suture jobs, and preserve the time and attention of the most skilled medics for the more serious injuries.
Assuming the light source can be shrunk and hardened(which given the impressive performance of modern solid state lighting and diode lasers is a definite possibility), you could probably get the whole system down to something that consists of a funny looking flashlight and some disposable tubes of glue, suitable for forward operating use by anybody who has had cursory training...

Yup. Remember that an injured soldier typically takes three soldiers to remove him/her, whereas a dead soldier takes one. Injured soldiers are a real drain on tactical effectiveness, unless one accepts the premise that it is best to just let them die or "put them out of their misery" so the mission can continue with the least loss of effectiveness. I submit that that may be tactically effective, but (a) unacceptably brutal, and (b) strategically ineffective unless one can sustain a war of attrition.
Rapid treatment not only saves lives (and provides a soldier to live to fight another day), but helps minimize the "expense" of triage and evac.

it's the possibility of damaging DNA that would be trouble
Risk/reward. What if there's a .00000001 chance of getting a melanoma from it? How does that stack up to post-surgical infection risk?
We're pretty good at DNA repair. Humans can take a 3 Rem exposure without much change in outcomes. Diet Coke contains mitochondrial DNA mutagens.
Given the choice at my local hospital, I'd take the chance and not have a big scar. My existing scar tissue has more problems than normal skin, so there are other risks down the line to consider as well.
