Bioethics, Volume 40, Issue 6, Page 558-564, July 2026.ABSTRACT Classical bioethics examines moral issues in terrestrial medicine and the life sciences. According to Konrad Szocik, space bioethics merely relocates those questions to harsher environments. We argue that this view is incomplete: space bioethics is a genuinely original domain.

A Proposal for Enhancing Technosignature Search toward the Galactic Center
The Astrophysical JournalWe discuss the possibility of enhancing intelligent life searches toward the Galactic center. From the clockwork orbital motions of stars around the Sgr A* black hole, we can determine the distance to the Galactic center at an exceptional accuracy ...

SEARCHING FOR ANOTHER EARTH: THE RECENT HISTORY OF THE DISCOVERY OF EXOPLANETS
Zygon, 2016 The discovery of exoplanets is a small part of the array of scientific arguments for and against the existence of extraterrestrial intelligence. Yet the recent stunning achievement of this program of observational astronomy has had a significant effect ...

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 ...

The Astrophysical Journal LettersThe LTT 3780 system hosts two known exoplanets—LTT 3780 b, a rocky super-Earth, and LTT 3780 c, a temperate sub-Neptune—orbiting a nearby M dwarf on opposite sides of the radius valley. LTT 3780 c has been proposed as a candidate Hycean world, making the

Disasters, Volume 50, Issue 3, July 2026.Abstract This study investigates the claim that women are disproportionately more likely to die in disasters by reviewing existing data sources and compiling new datasets on sex‐differentiated disaster fatalities in the twenty‐first century. The analysis is structured by disaster type, covering geophysical, meteorological, climatological, hydrological,

Exo–IPM Scattering as a Hidden Gatekeeper of Narrowband Technosignatures
The Astrophysical JournalNarrowband radio technosignatures can be significantly modulated by the host star’s exoplanetary interplanetary medium (Exo-IPM), where turbulence in stellar winds and coronal mass ejections (CMEs) imprint spectral broadening.

Multibeam SETI Observations Toward Nearby M Dwarfs with FAST
The Astronomical JournalThe search for extraterrestrial intelligence (SETI) targeted searches aim to observe specific areas and objects to find possible technosignatures. Many SETI researches have focused on nearby stars and their planets in recent years.
