It is interesting that there is a maximum amount of cold (absolute zero) whereas there is no maximum amount of hotness. Near absolute zero (or the coldest temperature in the universe) has been created on Earth only recently -- in a laboratory.
Quoted: Albert Einstein and the Indian physicist Satyendra Bose predicted in 1925 that scientists could generate such matter by subjecting atoms to temperatures approaching absolute zero. Seventy years later, Ketterle, working at M.I.T., and almost simultaneously, Carl Wieman, working at the University of Colorado at Boulder, and Eric Cornell of the National Institute of Standards and Technology in Boulder created the first Bose-Einstein condensates.

Ultimately, Ketterle, like many physicists, hopes to discover new forms of matter that could act as superconductors at room temperature, which would revolutionize how humans use energy.

Good point.
Quoted: These creatures set records for surviving in the most inhospitable places on Earth – their existence bodes well for finding alien life

Quoted: All four families have a few things in common. First, the people with Unertan syndrome are all the products of incestuous marriages. Children of closely-related people often suffer birth defects. Also, the children who walk on all fours are developmentally disabled; some are unable to talk.

Seems like an interesting development.
Quoted: People whose immune systems are resistant to the human immunodeficiency virus are causing it to mutate into a weaker form, which may improve survival odds in people with typical immune systems.

You must be Mohit's friend before you can comment on this Fave.Cold is really just the absense of heat, so a 'maximum amount of cold' is just a minimum amount of heat. They just glance over it in the article:
"To physicists, temperature is a measure of how fast atoms are moving, a reflection of their energy—and absolute zero is the point at which there is absolutely no heat energy remaining to be extracted from a substance. "
I don't know where they get off saying 'to physicists, temperature is...'. No, that is the SCIENTIFIC DEFINITION of temperature. It's not just something for physicists. Everyone should learn this.
I caught parts of this on Nova last night - several teams were able to create a Bose-Einstein condensate by cooling atoms down near absolute zero. Three people won the Nobel prize for this.
