Episode notes

Scientists experiment with compounds like epoxidized soy oil and catacol proteins to create a glue that mimics the adhesive properties of mussels and oysters, with comparable bond strengths to superglue and epoxy. The chapter explores the potential environmental benefits and challenges of this sustainable adhesive system, including the need for high heat and the quest for a reversible bond.

In this episode:

00:46 A sustainably-sourced, super-strong adhesive

The modern world is held together by adhesives, but these fossil-fuel derived materials come at an environmental cost. To overcome this, a team have developed a soya-oil based adhesive, which also takes inspiration from the proteins that marine animals like mussels use to stick firmly to rocks. The researchers say their glue is strong, reversible, and less carbon intensive to produce than existing adhesives.

07:43 Research Highlights

Why chemicals derived from wood could be sustainable alternatives to a common plastic building block, and how historical accounts helped researchers estimate the brightness of a 1859 solar flare.

10:08 New insights into childhood stunting and wasting

Around the world, millions of children are affected by malnutrition, which can result in stunting or wasting, both associated with serious health issues. Despite a widespread recognition of the seriousness of stunting and wasting, there are still questions about their extent, causes and consequences. To answer these, a team have pooled data from previous studies, and show that nutritional interventions targeting the earliest years of life could have the greatest impact.
