Toribio Rodríguez de Mendoza National University researchers conducted a genomic analysis of fine aroma cocoa from northern Peru, uncovering genetic divergence and evolutionary patterns within Theobroma cacao.
There is a trial of strength at the cellular level. Cells are in constant competition with each other and so eliminate diseased or unwanted cells. Cell competition is therefore a central principle for maintaining the health ...
