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.
