When Communication Enables Catastrophe: Nuclear Risk and the Short Lifetimes of Technological Civilizations

open access: yesRisk Analysis, Volume 46, Issue 9, September 2026.
ABSTRACT The Fermi paradox may partly reflect technological self‐destruction acting as a Great Filter during post‐industrial development. Because the empirical record consists of a single civilization observed over an eighty‐year nuclear age, the exercise reported here is best understood as a structured, historically anchored scenario analysis rather ...

Papaya‐Leaf‐Assisted Fermentation for Enhanced Extraction of Cassava Peel Starch and Its Application in Biodegradable Films

open access: yesStarch - Stärke, Volume 78, Issue 8, August 2026.
Papaya‐leaf‐assisted fermentation enhanced cassava‐peel starch recovery relative to fermentation without leaves and direct grinding, while lowering nitrogenous residues. Films plasticized with glycerol and acetic acid exhibited disrupted starch hydrogen bonding, loss of A‐type crystallinity, and pronounced hydrophilicity. Soil‐burial tests showed rapid,

Polarization Criterion in Targeted SETI Observation

open access: yesThe Astronomical Journal, 2023
In this paper, we propose a novel method for distinguishing extraterrestrial intelligence (ETI) signals from radio frequency interference (RFI) by leveraging polarization features.

CARGOISM AND SCIENTIFIC JUSTIFICATION IN THE SEARCH FOR EXTRATERRESTRIAL INTELLIGENCE

open access: yesZygon, 2019
This article compares justifications of the search for extraterrestrial intelligence (SETI) presented by scientists with ideational constructs associated with cargo cults in Melanesia. In focusing on similarities between cargoism and SETI, I argue that,

Habitat and Anthropogenic Determinants of Otter Presence in the Karnali River, Western Nepal

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
Despite increasing human pressures, otters persist along the Western Bend of the Karnali River. Occurrence of otters decreases with higher house density and presence of dogs. The study indicates otters tolerate some general human activity but strongly avoid settlements and dogs, highlighting the need for dog management, reduced settlement pressure, and

Alteration of Feldspar‐Rich Rocks on Ancient Mars and Its Possible Link to Ca/Fe‐Rich Carbonates

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract Feldspar‐rich rocks have increasingly been discovered on the martian surface. They may have been an important part of the ancient martian crust and may be related to Ca/Fe‐rich carbonates (one of two types of carbonates on Mars and the other being Mg‐rich carbonates), but compared to mafic rocks, their interaction with water on ancient Mars is

Thermodynamic Constraints on H2 Production and Habitability From Mg‐Rich Serpentinites as Mars Analogs

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Serpentinization produces hydrogen and methane through abiotic water‐rock interactions, potentially supporting chemotrophic life in planetary subsurface environments. Serpentine deposits in the Martian Noachian landscapes of Nili Fossae and the Southern Highlands have been considered as potential paleo‐habitable zones. However, the geochemical

Mutual Detectability: A Targeted SETI Strategy That Avoids the SETI Paradox

open access: yesThe Astronomical Journal, 2020
Abstract As our ability to undertake searches for extraterrestrial intelligence (SETI) grows, so does interest in the controversial endeavor of messaging extraterrestrial intelligence (METI). METI proponents point to the SETI Paradox—if all civilizations refrain from METI then SETI is futile.
