It's still time for another BIG and BRILLIANT adventure into the world of science on this week’s Science Quest!

In Science in the News, could an elephant foot bone discovered in  Spain be evidence of Hannibal’s legendary war elephants? A teacher in Wales has an ancient crocodile species named after him by a former pupil, and Saturday 21st February is World Pangolin Day, and to celebrate, Dan chats with Jessie Schrauger from the Pangolin Conservation and Research Foundation about the vital work being done to protect the world’s most trafficked mammals.

It’s time for your questions too. Isabel wants to know how lenses in glasses help us see clearly, and Luke Gaskill from Scout Adventures answers Marcus’ burning question: why is there smoke when there is a fire?

Dangerous Dan introduces the strange and subterranean purple frog.

And in Battle of the Sciences, Ian Mills makes the case for dentistry and the science behind keeping our teeth strong.

Plus, in Professor Hallux’s Map of Medicine, we investigate toothache and discover what really happens if you forget to brush.

What we learn about:

• Why fire creates smoke

• How lenses in glasses bend light

• Why brushing your teeth prevents cavities

• Possible evidence of Hannibal’s war elephants

• How pangolins are being protected

• The unusual purple frog

• What causes toothache

All that and more on this week’s Science Quest!
