What Is Space Bioethics?

Bioethics, EarlyView.
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.

Out There No One Has a Right to Die

Bioethics, EarlyView.
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 ...

How to Imagine Educational AI: The Filling of a Pail or the Lighting of a Fire?

Educational Theory, EarlyView.
Abstract Recent advances in artificial intelligence (e.g., machine learning, generative AI) have led to increased interest in its application in educational settings. AI companies hope to revolutionize teaching and learning by tailoring material to the individual needs of students, automating parts of teachers' jobs, or analyzing educational data to ...

Molecular Precursors of the RNA-World in Space: New Nitriles in the G+0.693−0.027 Molecular Cloud

Frontiers in Astronomy and Space Sciences, 2022
Nitriles play a key role as molecular precursors in prebiotic experiments based on the RNA-world scenario for the origin of life. These chemical compounds could have been partially delivered to the young Earth from extraterrestrial objects, stressing the

The interstellar object significance scale (Loeb Scale): astronomical classification of interstellar objects

International Journal of Astrobiology
Abstract The Vera C. Rubin Observatory is expected to increase interstellar object (ISO) detections from a few over the past decade to potentially one per few months, demanding a systematic classification scheme. We present the Interstellar Object Significance Scale (IOSS), also known in the literature as the Loeb Scale, a 0–10 ...

Architect of the Image: Argumentation, Economy and Translation in Gregory of Nyssa’s On the Human Image

International Journal of Systematic Theology, EarlyView.
Abstract In this contribution to a book symposium on Gregory of Nyssa’s On the Human Image, Morwenna Ludlow reflects on John Behr’s attention to the literary structure and argumentative flow of the book, its interplay with the similarly structured Timaeus of Plato and the difficulties of translating a work of such rhetorical and pastoral sophistication

An Upper Limit on the Interstellar Meteoroid Flux at Video Sizes from the Global Meteor Network

The Astrophysical Journal
Material arriving at our solar system from the Galaxy may be detected on Earth in the form of meteors ablating in our atmosphere. Here, we report on a search for interstellar meteors within the highest-quality events in the Global Meteor Network (GMN ...

Model Calculations for Cosmogenic Nuclides in Meteorites and the Lunar Surface. 1. Long‐lived Radionuclides

Meteoritics &Planetary Science, EarlyView.
Abstract Production rates for the cosmogenic radionuclides 10Be, 14C, 26Al, 36Cl, 41Ca, 53Mn, and 60Fe in a large variety of meteorites, that is, ordinary chondrites (H, L, LL), carbonaceous chondrites, HED meteorites, ureilites, Martian meteorites, and iron meteorites and in the uppermost ~2 m of the lunar surface are modeled.
