OF THE
TIMES

In a statement published after this article's publication, the GSA blamed the Galileo outage on "a technical incident related to its ground infrastructure." The agency said that the search and rescue (SAR) feature -- used for locating and helping people in distress situations for example at sea or mountains -- remained operational during the outage, which impacted only navigational and satellite-based timing services.

[T]he goldfish (and its cousin the common carp) went through a "whole genome duplication" after evolutionarily "splitting off" from zebrafish. Now, having four copies of every gene instead of two allows for one copy to change and evolve without harming the fish. This can result in lost genes or new functions for genes. This is a natural complement to "knockout" laboratory studies.
Add in the common carp genome with its own ornamental varieties (known as koi), and there are plenty of avenues of comparison to provide researchers with a window into how genes change during evolution. [Emphasis added.]
