I don't get it. How are you going to get enough oxygen (trapped in pockets of) a 3cc lipid injection to stay functioning? I breathe 10x that amount of air in a second. Even if I only get 1/10 of that as oxygen into my blood stream,... what that 3cc delivers is still practically nothing.

Liquids are much denser than gases.

This is VERY early reporting of a finding that needs more work in an animal model before anyone can try it with human patients. Searching on the investigator's name turned up a more informative article http://www.technologyreview.com/fromthelabs/428871/injectabl... that indicates some of the development steps that are still necessary.

Thanks for the necessary groundwork.

The OP is a terrifying vision of the future of journalism. A warmed-over rewrite of some press release, with no links to the original material, tarted up with an array of unrelated links so huge that they even creep into the author's byline:

I thought Ghostery would have a stroke. I'm just going to flag this.

So how long before this becomes the standard safety kit for moon/mars colonials?

When 30 minutes of additional breathing are enough time to bring a crew back to Earth or a space station. That is to say, in 340 years, give or take 5 years. By then they'll also bring condoms, because we will have realized that space isn't much good for a whole lot, except to have sex in it.

Living on mars without a helmet? :D

The pressure difference because of lack of atmosphere would cause strange effects (I don't know what might be, I'm no physicist).

I saw it in a movie. I think it was called Total Recall :)

It's a tabloid, nothing to fear for the future over.

Especially since this is two month old news.

Earlier quoted context omitted.

I think since the moon doesn't have an atmosphere, the vacuum will quickly tear you apart from liquid evaporation anyway.

Not so. Your skin is actually more than strong enough to prevent your blood from boiling. And without an atmosphere, radiative cooling is really slow. Exposure to vacuum (or just really low atmospheric pressure) kills you by anoxia after a couple of minutes; less than a minutes of exposure tends to do no lasting damage, unless you try to hold your breath and end up rupturing alveoli.

I think you make it seem slightly more harmless than it is..

http://wiki.answers.com/Q/What_will_happen_to_a_person_witho...

After about ten seconds a victim will experience loss of vision and impaired judgement, and the cooling effect of evaporation will lower the temperature in the victim's mouth and nose to near-freezing. Unconsciousness and convulsions would follow several seconds later, and a blue discoloration of the skin called cyanosis would become evident.

At this point the victim would be floating in a blue, bloated, unresponsive stupor, but their brain would remain undamaged and their heart would continue to beat. If pressurized oxygen is administered within about one and a half minutes, a person in such a state is likely make a complete recovery with only minor injuries, though the hypoxia-induced blindness may not pass for some time. Without intervention in those first ninety seconds, the blood pressure would fall sufficiently that the blood itself would begin to boil, and the heart would stop beating. There are no recorded instances of successful resuscitation beyond that threshold.

The technique in the article is small bubbles filled with gas.

How do you remove carbon dioxide?

Indeed! So now you've got 30 minutes worth of CO2 hanging around in your blood... Surely that's going to cause some issues? Anyone with some biology smarts able to explain if this would be a problem?

That aside, I wonder what the nano-med applications are for this. For example an implant for high-risk patients that injects a dose upon respiratory failure etc. Heck if it were feasible such would be handy for anyone to have.
