Dinosaurs homeostasis

If dinosaurs were ectotherms how would a very large dinosaur such as a T Rex or Diplodocus ever warm itself up enough from its surroundings to move, let alone run? Bearing in mind they were huge and so had a v. large vol:SA ratio. Was it because the world's climate was much warmer then?

topical steroids

Is it possible to become 'resistant' or 'immune' to topical steroids eg hydrocortisone used for eczema? As in will their effectiveness decrease with usage?

Testing for life

A question I've been thinking about, I think it was featured in New Scientist: What would be a reasonable experiment to test whether something was alive or not? (Taking into account that we don't actually have a definition for 'life' yet!)
