Summary
The self-supporting structures that snap into place, and how a ban on fossil-fuel funding could entrench poverty in sub-Saharan Africa.
In this episode:
00:45 Self-supporting, foldable structures
Drawing inspiration from the art of origami, a team of researchers have demonstrated a way to design self-supporting structures that lock into place after being inflated. The team hope that this technique could be used to create arches and emergency shelters that can be quickly unfolded from flat with minimal input.

09:55 Banning fossil-fuel funding will not alleviate poverty
A ban by wealthy nations on the funding of overseas fossil-fuel projects would do little to reduce the world’s climate emissions and much to entrench poverty in sub-Saharan Africa, argues economist Vijaya Ramachandran.
