Bacteria stored in 25% glycerol can be deep-frozen for years and still be able to divide after thawing. More complex organisms cannot be revived after freezing because glycerol cannot permeate their cells quickly enough, and doesn't prevent the ice crystals forming inside to rupture the cells. Moreover, freezing disrupts certain biochemical pathways that cannot be restarted in more complexely organized cells.

Yes, we routinely freeze bacteria at -80C then revive them years later. Some reptiles can freeze and then revive when the temperature increases after winter. Also frozen embryos are routinely used in IVF clinics. The human egg is fertilized then frozen in liquid nitrogen. It can be stored for many years this way. The embryo is then thawed and inplanted into a woman's womb to so that it can develop into a baby.

BActeria (e.coli)can be frozen up to -40C (that I know about) and then thawed in a heat block, placed in a media rich in sugars and will begin reproducing immediately. Some that I worked with were frozen for many (>10) years before being used.

You can do that with lobster. In fact, I saw a program on Food Channel that shows a company selling lobsters on the internet, arrived frozen but you can revive. But I don't think it lasts a year, though.

Nope, yet people still get themselves cryogenically frozen with hopes that this may one day become a possibility. Among the most famous of these optimists is baseball player Ted Williams (currently frozen).

Not yet. When you freeze human tissue, the water in the cells expands and forms crystals, rupturing the cell walls. Science needs to find a way around that first.

Been trying for a long time and so far no. No telling how many living creatures were frozen alive to try and find out.

yes, it works on certain animals that aren't hugely water based, like crustaceans, crabs, lobsters. It works with some amphibians also. Animals that are water/carbon based, our blood and water will expand when frozen, which causes things to become severely warped internally.

Bacteria. A moth got in my freezer, and came back to life days later when I took it out and let it sit.

Without the proper equipment & training....I don't think so.
