This amazing creature has a fittingly amazing name: the psychedelic earth tiger, also known as the Indian rainbow . It appears on Fauna & Flora’s 10 species to watch in 2026, a list of animals the conservation charity is hoping to protect. The list also includes extremely venomous vipers, a highly prized falcon and a guitarfish which looks like it has been sewn together from two different species in a “misguided scientific experiment.”

"Whether or not we realize or acknowledge it, our memories can have considerable impact on us, perhaps even going so far as to define our character and drive our motivations, for better or worse. This is especially true when it comes to significantly powerful recollections, the kind that leave a profound, lasting impression on us and our psyche."

"But are these remembrances fixed and unalterable, essentially representing unshakable, infallible records of past experiences? Or can they shift over time, despite perpetual reinforcement that makes them seem like they're fundamentally unchangeable? And how does that affect us in terms of our character, perspective and actions?"

From a review of We Shall Not Be Moved

The U.S. military maintains a permanent presence at Pituffik air base in northwest Greenland under a 1951 agreement granting freedom to build bases with Danish and Greenlandic notification. Denmark has historically accommodated the U.S. presence because Copenhagen does not have the capability to defend Greenland and benefits from U.S. security guarantees through NATO.
