The coldest erupting lava in the world is the natrocarbonatite lava of the volcano Oldoinyo Lengai, Tanzania that erupts at temperatures of 500-600°C (930-1,110 °F). Common basaltic lavas erupt at temperatures between 1,100 and 1,200°C (2,010-2,190 °F). Oldoinyo Lengai is the only active carbonatite volcano on Earth. The bizarre carbonatite lavas look rather like molten chocolate upon eruption. It is extremely runny and has the lowest viscosity of any lava. Upon cooling it turns white in colour.

In Tanzania, Africa, rats are being trained by a Dutch Non Governmental Organisation (APOPO) to sniff out landmines, having already been used successfully in Mozambique for this purpose. Out of nearly 2,000 species in the order of rodents, the Giant African Pouched Rat (Cricetomys gambianus), is the favoured animal, as it is found everywhere in sub-Saharan Africa and is resilient to most tropical diseases. They are a cost effective and efficient way of undertaking what is otherwise a highly dangerous task for human operatives. The Continue reading →
