Evolution![Figure][1] CREDIT: OYSTEIN WIIG, UNIVERSITY OF OSLO Polar bears are adapted to living in one of the harshest environments on earth, their range being determined by the extent of Arctic polar sea ice. They arose from the brown bear lineage and are most closely related to a group of genetically distinct brown bears that inhabit the ...

Gender & Society, 2005
Bears comprise a subculture of gay men who valorize the larger, hirsute body. This research interrogates Bear culture as a gendered strategy for repudiating effeminacy that simultaneously challenges and reproduces norms of hegemonic masculinity. In this research, the author situates his ethnographic study of a major metropolitan Bear community in its ...

Global Change Biology
Brown bears across Europe are responding to the human footprint, with space use and movement behaviour strongly influenced by limited habitat connectivity. While natural food availability and habitat suitability remain important for bears, growing human pressure is increasingly constraining their ecological role. The picture was drawn by Andrea Gazzola.

Powder Metallurgy, 1969
The first suggestion that the porous products of powder metallurgy could be used as self-lubricating bearings appears to have been made sometime in the early 1920s. The idea probably originated from attempts to overcome the heat conductivity limitation of oil-soaked wooden bearings.
