collections of quotes Just a FYI.. Tinyurl installs spyware/adware if
you use
it to browse...
Sorry for the crosspost, but what about snipurl.com?

Is this an occasion of there is no such thing as a free lunch? Don't want
to
use these if that is the case.

Garee's claim of tinyurl installing spyware is false. He probably went to a
tinyurl link for a site that had pop-up ads and one of those pop-up ads
attempted to install spyware.

Literally all tinyurl does is redirect the browers to the other site.
Another site that is pretty good, is http://xrl.us/

Someone got me using http://www.makeashorterlink.com and it's great.

I don't _think_ that living through anoxia is unique, anyway; the

Even people can survive what is effectively death by drowning if they
are cold enough, I believe.

Yep one guy (actually I think it was a kid) "survived" 45 minutes under freezing
water and was resuscitated without brain damage

Yes, that is true. TinyURL.com is all server side, which means there is no
processing or software on your machine. Of course they also have the TinyURL
toolbar now, that could be the source of the OP's fear.

Anaerobic bacteria ?

So can I. About 6-7 minutes.

There's some basic biology that needs to be reviewed. The first portion of
carbohydrate metabolism (glycolysis) does not require oxygen and does
produce some energy. In presence of oxygen, this continues into the Krebs
cycle and oxidative phosphorylation in the mitochondria which produces
more energy. In the absence of oxygen, this instead ends and the product
of glycolysis is converted into lactate (lactic acid) by an enzyme.

For example, human muscles can operate via anaerobic metabolism or a mix
of anaeobic and aerobic metabolism. In muscles, a limited source of energy
can be stored in resting muscles. This store is used first before
metabolic pathways (both aerobic and anaerobic) when the muscle contracts.
In intense exercise (note "intense" has an individual meaning here with
respects to the individual's conditioning), glycolysis only (anaerobic)
becomes a predominant mode of producing energy but with the side effect of
lactic acid build-up and requiring more oxygen to rebuild energy stores
after exercise. Lactic acid also contributes to muscle fatigue and can
cause metabolic acidosis (due to the higher presence of H+ ions).

A few things to note. One, energy is produced when oxygen is not present,
just not as much as when oxygen is present. Two, you get a build-up of
lactic acid using the anaerobic pathways. Three, a build-up of lactic acid
can have detrimental effects on the body as a whole. It sounds like these
fish have an additional metabolic pathway to excrete lactic acid so that
they do not get acidosis and muscle fatigue due to high lactic acid
concentrations, but I have not actually read the study.

yes but they are bacteria not animals. Do bacteria have lungs or equivalent?

Dunno... there might be anaerobic multicellurals near geothermal vents...
