A mussel-inspired glue for more sustainable sticking

In this episode:00:46 A sustainably-sourced, super-strong adhesiveThe 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.Research article: Westerman et al.07:43 Research HighlightsWhy 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.Research Highlight: Wood component yields useful plastics — without the health risksResearch Highlight: A historic solar flare’s huge intensity is revealed by new tools10:08 New insights into childhood stunting and wastingAround 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.Research article: Benjamin-Chung et al.Research article: Mertens et a...
