When I was in High School one of my classmates decided to do his annual science fair project on cryogenics. It was a relatively new science in the mid 1980’s and a subject of the pop science of the time. He studied this subject by freezing goldfish in liquid nitrogen (surprisingly easy to acquire it turns out) and attempting to thaw them in the microwave – hoping to return them to life.
Needless to say this didn’t work – as I remember from his conclusion (a key part of the science fair project) largely because the fish cracked. QED.
However now comes word (courtesy of PBS’ Nova) that, while it is unlikely he would have ever succeeded with fish, had he used the common wood frog he would have indeed been able to freeze the frog and return it to life. As you can see on their web site, this frog has the uncanny ability to let itself freeze completely in the winter, only to come back with the spring thaw.
Life truly is amazing.
