Commander Peary's Expedition to the North Pole

The North Ecliptic Pole Supercluster

We have used the ROSAT All-Sky Survey to detect a known supercluster at z = 0.087 in the North Ecliptic Pole region. The X-ray data greatly improve our understanding of this supercluster’s characteristics, approximately doubling our knowledge of the structure’s spatial extent and tripling the cluster/group membership compared to the optical discovery data. The supercluster is a rich structure c...

Sleep profiles and mood states during an expedition to the South Pole.

OBJECTIVE To study sleep parameters and mood profiles of a female explorer traveling solo and unaided to the South Pole during the winter.

From 'third pole' to north pole: a Himalayan origin for the arctic fox.

The 'third pole' of the world is a fitting metaphor for the Himalayan-Tibetan Plateau, in allusion to its vast frozen terrain, rivalling the Arctic and Antarctic, at high altitude but low latitude. Living Tibetan and arctic mammals share adaptations to freezing temperatures such as long and thick winter fur in arctic muskox and Tibetan yak, and for carnivorans, a more predatory niche. Here, we ...
