...xtensive body of research has helped us understand why the sexes of particular species have evolved differences, but this sort of work has not previously been put into a broader context to understand how significant sexual dimorphism is in the grander scheme of evolutionary diversification." Found acro...Scientists identify prion's infectious secret
... with a new way to approach old questions, such as why some prion diseases can jump from one species to another but others cant. Tessier and Lindquist say it is likely that natural prions contain more than one recognition element, and recognition elements can slide into a neighboring region. Many externa...UC engineering researchers uncover factors that control ion motion in solid electrolytes
... next step in their research will be to understand why traces of water change the behavior of these electrolytes so drastically and to understand if the behavior observed here of three elastic domains is a general feature of all electrolyte glasses or is it peculiar to this very well studied material.
