Automated Mineral Identification and Rock‐Type Classification of Lunar Mare Basalts Using SEM Images

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract We present an automated system for identifying minerals and classifying rock types in Apollo lunar mare basalts using scanning electron microscopy (SEM) imagery. Mineral segmentation is based on a U‐Net architecture, supplemented by two scale‐aware models designed to incorporate pixel size information.

Falling Forward : The Fermi paradox, supermassive black holes, and the likely flight of extraterrestrial intelligence toward extreme time dilation.

, 2023
It is argued that an advanced extraterrestrial intelligence has an overwhelming incentive to permanently occupy a reference frame where time is greatly slowed by relativistic effects.

Contemporary disasters may not kill more women than men: an empirical inquiry into sex‐differentiated fatalities in the twenty‐first century

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,

The Local Galactic Transient Survey Applied to an Optical Search for Directed Intelligence

The Astrophysical Journal
We discuss our transient search for directed energy systems in local galaxies, with calculations indicating the ability of modest searches to detect optical Search for Extraterrestrial Intelligence sources in the closest galaxies. Our analysis follows P.

A Search for Extraterrestrial Technosignatures in Archival FAST Survey Data Using a New Procedure

The Astronomical Journal, 2023
The search for extraterrestrial intelligence (SETI) commensal surveys aim to scan the sky to find possible technosignatures from an extraterrestrial intelligence (ETI). The mitigation of radio frequency interference (RFI) is an important step, especially

Proton‐Radiation Hardening of High‐Speed Ge/Si Integrated Photodetectors for Space Applications

Nanophotonics, Volume 15, Issue 12, 25 June 2026.
Hydrogen loading is demonstrated as a radiation‐hardening strategy for high‐speed Ge/Si integrated photodetectors under broadband proton irradiation. By suppressing irradiation‐induced leakage‐current growth and mitigating bandwidth degradation, hydrogen‐loaded devices maintain high‐speed operation and improved stability, providing a practical route ...

Using Anomaly Detection to Search for Technosignatures in Breakthrough Listen Observations

The Astronomical Journal
We implement a machine learning algorithm to search for extraterrestrial technosignatures in radio observations of several hundred nearby stars, obtained with the Parkes and Green Bank Telescopes by the Breakthrough Listen collaboration.
