[thedoc (OP)]

This week, we uncover an ideal anti-freeze for ice-cream, find out how scientists grew a new heart in a dish and hear how four simple lifestyle changes could make you live fourteen years longer.  Also, we find out about the technology of the future, the tropical Paris of the past and the crystal secret behind the silvery sheen on fish scales.  Plus, we asked for your questions and the floodgates opened!  Why isn't your urine affected by coloured drinks and what does it mean if it's frothy?  What happens when a lake is struck by lightning, and do you weigh less at the equator?  Meanwhile, in Kitchen Science, we also show you how to make an Oboe out of a drinking straw!
