Solvent constraints for biopolymer folding and evolution in extraterrestrial environments

open access: yesProceedings of the National Academy of Sciences
We propose that spontaneous folding and molecular evolution of biopolymers are two universal aspects that must concur for life to happen. These aspects are fundamentally related to the chemical composition of biopolymers and crucially depend on the solvent in which they are embedded. We show that molecular information theory and energy landscape theory

The Moral Status of Extraterrestrial Life

open access: yes, 2012
If we eventually discover extraterrestrial life, do we have any moral obligations for how to treat the life-forms we find; does it matter whether they are intelligent, sentient, or just microbial-and does it matter that they are extraterrestrial? In this

The truth is out there: the structure of beliefs about extraterrestrial life among Austrian and British respondents

open access: yes, 2009
Previous investigators of extraterrestrial beliefs have relied on single-item scales, which limit the researchers' understanding of such beliefs. The present authors report responses to a 37-item scale about extraterrestrial beliefs from 320 participants

Effect of Laboratory Reagents for Cleaning Modern Contamination on the δ15N Integrity of Nitrogen‐Poor Samples

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 19, 15 October 2026.
ABSTRACT Rationale Nitrogen isotope values have been widely used for tracing ancient biogeochemical processes, but contaminant‐sensitive materials, such as Precambrian sedimentary rocks, meteorites, or returned extraterrestrial samples, often have low nitrogen levels and are thus vulnerable to modern organic contamination.
