Genomic divergence of hatchery- and natural-origin Chinook salmon (Oncorhynchus tshawytscha) in two supplemented populations
Captive propagation is widely used for the conservation of imperiled populations. There have been concerns about the genetic effects of such propagation, but few studies have measured this directly at a genomi...

A tortoise approach for US nuclear research and development
In Aesop’s fable, a swift hare races with a deliberate tortoise. In the end, the tortoise wins by taking a slow and steady approach. We argue that, given the economic constraints on US deployment of nuclear po...

Competition of van der Waals and chemical forces on gold–sulfur surfaces and nanoparticles
Chemists generally believe that covalent and ionic bonds form much stronger links between atoms than the van der Waals force does. However, this is not always so. We present cases in which van der Waals disper...
