This article investigates human–nature relations in the light of the recent call for degrowth, a radical reduction of matter–energy throughput in over-producing and over-consuming cultures. It outlines a culturally sensitive response to a (conceived) paradox where humans embedded in nature experience alienation and estrangement from it. The article finds that if nature has a core, then the experienced distance makes sense. To describe the core of nature, three temporal lenses are employed: the core of nature as ‘the past’, ‘the future’, and ‘the present’. It is proposed that while the degrowth movement should be inclusive of temporal perspectives, the lens of the present should be emphasised to balance out the prevailing romanticism and futurism in the theory and practice of degrowth.

Recent studies of polymers in solution and in bulk by energy transfer between two fluorescent labels are reviewed. Such studies are concerned with the equilibrium and dynamics of polymer chain expansion, molecular cluster formation in solution, the miscibility of polymers in bulk, and the interdiffusion of polymer latex particles.
