Episode notes

First test flight was just fly up for a few meters, turn round, i think, 96 degrees, and fly down. More flights are planned for the next few weeks to try and put it through more of its paces. The signal from the helicopter was beamed to the rover that was then beamed to an orbiter which was then beamed back to a big dish here on earth. It's a very, very long way away, so this was kind of autonymous.

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.

07:32 Research Highlights

Nocturnal fluctuations cause scientists to underestimate rivers’ carbon emissions, and the ‘island rule’ of animal size-change is seen around the world.

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.
