COSMIC’s Large-scale Search for Technosignatures during the VLA Sky Survey: Survey Description and First Results

The Astronomical Journal
Developing algorithms to search through data efficiently is a challenging part of searching for signs of technology beyond our solar system. We have built a digital signal processing system and computer cluster on the backend of the Karl G.

Current understanding of electroautotrophy and its relevance in astrobiology‐related research

mLife, Volume 4, Issue 5, Page 473-493, October 2025.
Abstract Electroautotrophy—the use of extracellular electrons as the primary energy source for autotrophic metabolism—remains understudied compared to photoautotrophy and chemoautotrophy. Its occurrence in deep‐earth and deep‐sea environments suggests profound implications for astrobiology, yet electroautotrophic microorganisms remain poorly explored ...

Sleep and Dreams as Reflected by Science Fiction Literature and Films—Anything to Learn From?

Journal of Sleep Research, Volume 34, Issue 5, October 2025.
ABSTRACT Sleep and dreams are frequent themes in science fiction (Sci‐Fi) literature and films, often used to explore questions about consciousness, reality, technology and the human experience. Sci‐Fi authors and filmmakers utilise the enigmatic nature of sleep and dreams to blur the boundaries between reality and imagination, raising philosophical ...

Detecting Biosignatures in Complex Molecular Mixtures From Pyrolysis‐Gas Chromatography‐Mass Spectrometry Data Using Machine Learning

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 3, September 2025.
Abstract Understanding how measured molecular signals can distinguish the chemistry of life from the chemistry of the nonliving world is a central focus of astrobiology and paleobiology. We train and compare several machine learning (ML) classification models on data from pyrolysis‐gas chromatography‐mass spectrometry (py‐GC‐MS)—a widely available ...

Examining the Quantification Capability of Automated Mineralogy System: A Machine Learning Approach

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 3, September 2025.
Abstract Automated mineralogy (AM) systems are a novel platform for material characterization. By analyzing the X‐rays generated from sample–electron interactions, these systems can rapidly and automatically provide mineralogical and textural descriptions of a sample.

Reports of Non‐Physical Beings Assisting in Reiki Sessions

Anthropology of Consciousness, Volume 36, Issue 2, Fall 2025.
ABSTRACT The belief in non‐physical beings playing crucial roles in illness and healing is widespread across diverse cultures. Our previous study found reports of alleged non‐physical beings during energy medicine sessions. To evaluate the perceived presence and characteristics of non‐physical beings mentioned during Reiki sessions.

A Review of Photonics‐Driven Thermal Management: Strategies for Efficient Energy Generation and Saving

EcoMat, Volume 7, Issue 8, August 2025.
Photonics plays a crucial role in thermal management by manipulating electromagnetic waves for energy production and efficiency. This review explores strategically designed photonic structures that leverage both solar absorption (UV–NIR) and thermal emission (MIR) for heating and cooling applications.

Joint Extraction Method for Spatial Relations in Chinese Geological Texts

Earth and Space Science, Volume 12, Issue 8, August 2025.
Abstract Extracting spatial relations of geological entities is an important prerequisite for achieving natural language processing tasks such as geological knowledge question answering and semantic search, and is an important means to achieve structural reconstruction of unstructured geological data.
