It is published by the Society for Science, a nonprofit 501(c)(3) membership organization dedicated to public engagement in scientific research and education. An ancient diamond found in Botswana contains a never-before-seen mineral that came from deep inside Earth. Scientists can only speculate right now what the source was for the extra potassium, but this unexpected composition hints that the lower mantle may be a more motley mix than thought, with complexity difficult to predict from lab studies alone. In short, botho can be referred to as a yardstick for good behaviour, which is consistent with the expectations and cultural norms of Setswana society. Questions or comments on this article?
