Episode notes

Shumney is happy this week cause i have dinosars. No, no, i feel about dinosaus. How many t rexes were there? I'm in a te company indi just ask me to work out how many t rexes, what that ever lived. And i'll show my workings on the podgast if you want a i mean, i imagine, i mean, we have some fossils,. but that's not all of the fossils. If it was ther'd only be a, what, 12 teranasars wrecks that ever lived. A team from university of california at berkeley basically done that in a paper in science. They concluded

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.
