Dear Science: Nazis hate trees, Chemical recycling and Allan is Einsteins biggest fan

On todays segment of Dear Science with AUT's Allan Blackman, we talk about a Nazi warship during WW2 damaging the growth of Norweigan trees using chemical smokescreens. Allan takes us into the fascinating world of chemical recycling using enzymes, bacteria and some awesome science. And finally Will thinks its Einsteins birthday anniversary but alas its the anniversary of the day he died, Allan is quite sad about this.
