Ferociously attacking with its sting and its jaws simultaneously, the bulldog ant Myrmecia pyriformis holds the world record for “most dangerous ant.” And in the dry forests of eastern Australia, the ants are the mortal enemies of the social huntsman spider, Delena cancerides. The two species forage at the same time -- starting around twilight and lasting throughout the night -- in the same places.
Genetically modified (GM) crops have been used to feed livestock since 1996, and it now makes up to 90% of all animal feed in the United States. Since this introduction, there has been massive controversy surrounding the safety of this practice. Unfortunately, the validity of the conversation has been sullied by anecdotal evidence and “studies” in journals not subjected to peer review that claim GM food causes a host of physical ailments, including cancer.

Roughly 75 million years ago during the Late Cretaceous, Rhinorex condrupus lived out its days eating plants in what is now Utah.

While Rhinorex didn’t have the decorative crest, it did have a defining facial feature: an extremely large, hook-shaped nose.

Their advanced cognition allows them to live in complex, dynamic social environments, according to a new study published in The Auk: Ornithological Advances.
