The Daily Galaxy article you link it is terrible. It contains many errors, including this hilariously bad sentence:

In "Houston We Have a Problem" lingo, NASA doesn't have no clue about what this is, and they are still speculating about how this object was formed. But, its 460-foot-wide nucleus is outside the dust halo and separated from the trail -behavior which has never been seen before in a comet or any other solar-system-traversing object.

I recommend this article by the Bad Astronomer, Phil Plait, instead.

Ed Yong: "Toads are an evolutionary success story. In a relatively short span of time, they diversified into around 500 species"

Success story? Are you kidding? If toads were successful, they wouldn't have had to produce 500 species, would they? One would have sufficed. Like humans (another evolutionary success story ;)). The coelacanth, now there's an evolutionary success story.
