When is a tree not a tree? When it’s a rock(!)
By way of an introduction to “ergastic substances” in plants, Mr P Cuttings considers calcium oxalate and carbonate. And relates this to a report that certain fig trees can sequester such inorganic carbon, potentially maintaining carbon sinks post-death. This biomineralisation could help to mitigate climate change while also benefiting soil…

When volcanology meets plant biology*
Research by Guinn et al. (2024) indicates that volcanic CO2-enhanced plant growth, is detectable via satellite using the NDVI metric. Greener vegetation can be used as a proxy for increased CO2 release from volcanoes, serving as an early warning for volcanic activity. This method can also be used to monitor…

What’s the beef with hybrid rice?
This post discusses various types of coloured rice, including black, purple, blue, yellow, red, and pink rice. It also considers a new “pink rice” created in a laboratory by integrating rice grains with animal cells. Two hopes for this hybrid food are to address concerns around climate change, and provide…

Tree planting, a hot topic…
This post discusses the significance of trees to humans, and highlights how trees provide not only physical resources but also essential ecosystem services. While tree-planting is a popular solution to mitigate climate change, it can have unintended consequences related to global warming. Addressing these issues will require thoughtful and evidence-backed…
