The Front‐End of Circular Innovation in Incumbent Firms
Journal of Product Innovation Management, EarlyView.ABSTRACT The Circular Economy introduces ambiguity and complexity when developing products and services, by using materials and resources differently; innovations and related business models thus deviate markedly from those evident in the “linear economy”.

Meteoritics &Planetary Science, EarlyView.Abstract Since the discovery of nine meteorites near the Yamato mountains in 1969, Antarctica has been recognized as a superb location for meteorite recovery. While Antarctic recovery expeditions prioritize meteorite preservation for mineralogical and planetary studies, meteorites are not typically collected for biological applications.

Out There No One Has a Right to Die
Bioethics, Volume 40, Issue 6, Page 565-572, July 2026.ABSTRACT The eventual goal of space exploration is to colonize exoplanets and their moons outside our solar system. This is a dangerous and immoral endeavour. The extraterrestrial life forms encountered would be hostile, vulnerable or both, and the descendants of the original pioneers would be involuntarily exposed to hazardous conditions and ...
