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 ...

Challenges and Opportunities for Strengthening Bottom‐Tow Fisheries Sustainability
Fish and Fisheries, Volume 27, Issue 4, Page 987-1005, July 2026.ABSTRACT Bottom‐tow gear fisheries (trawls and dredges) produce ~24 million mt of harvest annually, representing a globally important animal‐sourced food system. While many are currently sustainably managed, growing concern over the potential for ecosystem impacts from bottom‐tow gears has increased pressure to improve these fisheries.
