Explorer, paleoanthropologist and evolutionary biologist Ella Al-Shamahi joins us this week to chat about where we may see the earth in 7 years time and her defying new show Our Changing Planet! 

In Science in the News we hear about the Mars Rovers latest progress in its expedition and we answer your questions, this week we find out why we get sore throats and why the sky is blue!

We also catch up with Professor Hallux and Nurse Nanobot in their Map of Medicine series, and today we better sit up straight as its all about back pain and posture! In our new Deep Space High Series we are looking back on the earth to find out about gravity!
