Episode notes

Researchers used soiled nappies to test the strength of concrete. They found they could replace up to 40% of the sand that would have gone in with this shredded nappy mix. If you've got a sort of weight bearing structural component, like the columns and beams, those would need a much lower proportion - around 9%.

00:45 Tree islands bring biodiversity benefits for oil-palm plantation

Global demand for palm oil has resulted in huge expansion of the palm plantations needed to produce it, causing widespread tropical deforestation and species loss. To address this, researchers planted islands of native trees among the palms in a large plantation, and showed that this approach increases ecosystem health, without affecting crop yields. The team say that while protecting existing tropical rainforests should remain a priority, tree islands represent a promising way to restore ecosystems.
