Decoding our inner voice, and hunting for life on Mars

This week, we're taking on your science brainteasers! We find out why toothpaste ruins other flavours, whether humans have a mating season and why food goes in multicoloured, but comes out brown... Plus, fighting Fido's fleas with fungus, stressed men take more risks, and predicting if hepatitis B will lead to liver cancer. In Kitchen Science, we make a fruity fireball with orange peel.

This week we dig into into the science of farming and food production. We find out how transgenic plants can help us dispense with the need for chemical pesticides and how giant greenhouses at the shoreline can be home to super-efficient farms of their own. We explore the problems faced by our sweet honey bee and in Kitchen Science we do some plant modification of our own - no transgenics knowledge needed, just food colouring... Like this podcast?
