On Our Cosmic (In)significance

open access: yesRatio, EarlyView.
ABSTRACT This article discusses three interpretations of cosmic significance, all of which reveal something important about the notion of significance. Along the way, it proposes a unified view of significance by combining elements of each of the views.

Who Is Most Vulnerable to Conspiracist Ideation? Mapping Conspiracy Belief Profiles and the Psychological Characteristics That Differentiate Them

open access: yesScandinavian Journal of Psychology, EarlyView.
ABSTRACT Conspiracy beliefs are consequential for politics, public health, and trust in science, yet less is known about the psychosocial characteristics associated with different patterns of endorsement across conspiracy domains. The aim was to identify latent profiles of conspiracy belief and test whether profiles differ on psychosocial ...

Photosynthesis and Photo-Stability of Nucleic Acids in Prebiotic Extraterrestrial Environments [PDF]

open access: yes, 2014
Laboratory experiments have shown that the UV photo-irradiation of low-temperature ices of astrophysical interest leads to the formation of organic molecules, including molecules important for biology such as amino acids, quinones, and amphiphiles. When pyrimidine is introduced into these ices, the products of irradiation include the nucleobases uracil,

Triton as an archetype for icy ocean worlds: Key scientific drivers for future exploration

open access: yesFundamental Research
Ocean worlds (a subset of icy satellites) are among the most promising targets in the search for extraterrestrial habitability and biosignatures. Triton stands out due to its capture from the Kuiper Belt, geological activity, and potential subsurface ...

Extraterrestrial Sources of Prebiotic Molecules

open access: yes, 2009
The talk discusses the following questions (i) what are prebiotic molecules, (ii) which possible sources of these molecules do we know, (iii) which prebiotic molecules could be extraterrestrial, (iv) how can we verify their origin, and (v) are they ...

Extraterrestrial [PDF]

open access: yes, 2014
Electrochemical sensors, especially ion-selective electrodes, are ideally suited for analyses of extraterrestrial environments where comparatively little is known about the chemistry: they have remarkably high sensitivity over a wide dynamic range and ...

Multi‐Timescale Drought Evolution in Greece (1960–2022) From Station‐Based SPI and SPEI

open access: yesInternational Journal of Climatology, Volume 46, Issue 13, 15 November 2026.
Using homogenized data from 67 HNMS stations in Greece (1960–2022), we calculated SPI and SPEI at 1–12‐month scales to characterize meteorological to hydrological drought. We quantified the network‐based spatial extent of drought, compared SPI and SPEI drought signals, and tested changes with autocorrelation‐robust Mann–Kendall trends and Pettitt ...
