New tool to save salmon: Isotope tracking

A cross-section of a salmon otolith, also known as a fish ear stone or fish ear bone. By measuring strontium isotope ratios in different layers of otoliths from salmon caught at sea, researchers from the universities of Utah, Washington and Alaska Fairbanks and the U.S. Geological Survey were able to determine not just the watershed, but a set of streams where the salmon hatched and grew before migrating downstream to the ocean. The new fish-tracking method may help pinpoint critical habitats for fish threatened by climate change, industrial development and overfishing.Salmon carry a strontium chemical signature in their "ear bones" that lets scientists identify specific streams where the fish hatched and lived before they were caught at sea. The new...

Caltech astronomers observe a supernova colliding with its companion star

This is a still from a simulation of a Type Ia supernova. In the simulation, a Type Ia supernova 
explodes (dark brown color). The supernova material is ejected outwards at a velocity of
about 10,000 km/s. The ejected material slams into its companion star (light blue). Such a
violent collision produces an ultraviolet pulse which is emitted from the conical hole carved out by the companion star.Type Ia supernovae, one of the most dazzling phenomena in the universe, are produced when small dense stars called white dwarfs explode with ferocious intensity. At their peak, these supernovae...
