"For me science isn't a subject, it's a perspective. There are fascinating scientific aspects to everything from ancient history to the latest gadgets, outer space to interior decorating; and each week on The Material World we try to reflect the excitement, ideas, uncertainties, collisions and collaborations as science continues its never-ending voyage into the unknown".

Quentin Cooper talks to Alison Benjamin amateur beekeeper and co-author of 鈥淎 World Without Bees鈥 and Dr Nigel Raine, bee ecologist from Queen Mary University in London to find out.

But 100 years later scientists are yet to find an impact crater or tell-tale meteorite remains.
So what happened?
Quentin is joined by Dr Phil Bland and Gareth Collins from Imperial College London to find out.
