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

open access: yesEcoMat, 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.

A Bayesian Analysis of Technological Intelligence in Land and Oceans

open access: yesThe Astrophysical Journal, 2023
Current research indicates that (sub)surface ocean worlds essentially devoid of subaerial landmasses (e.g., continents) are common in the Milky Way and that these worlds could host habitable conditions, thence raising the possibility that life and ...

Joint Extraction Method for Spatial Relations in Chinese Geological Texts

open access: yesEarth 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.

Multi‐Module Micro/Nanorobots for Biomedical and Environmental Remediation Applications

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 7, July 2025.
Multi‐module microrobots (MNRs) have overcome the limitations of single‐module systems by integrating components such as propeller, actuator, manipulator, and imaging modalities. They show promise in biomedical applications, such as targeted drug delivery and tissue repair, as well as in environmental remediation, including pollutant removal.

Signal coverage approach to the detection probability of hypothetical extraterrestrial emitters in the Milky Way

open access: yes, 2017
The lack of evidence for the existence of extraterrestrial life, even the simplest forms of animal life, makes it is difficult to decide whether the search for extraterrestrial intelligence (SETI) is more a high-risk, high-payoff endeavor than a futile ...

Deep Space Network Radio Science and Ground‐Based Planetary Radar in the Next Decade

open access: yesRadio Science, Volume 60, Issue 7, July 2025.
Abstract The Deep Space Network (DSN) has been a core operational element of NASA's crewed and robotic exploration of the Solar System since the early 1960s. The primary role of the DSN has been to acquire telemetry and navigation data, but over the years, its radiometric and radar capabilities have expanded to form a system for obtaining unique ...

A Proposal for Enhancing Technosignature Search toward the Galactic Center

open access: yesThe Astrophysical Journal
We discuss the possibility of enhancing intelligent life searches toward the Galactic center. From the clockwork orbital motions of stars around the Sgr A* black hole, we can determine the distance to the Galactic center at an exceptional accuracy ...

The artisanal underground: gold, subsistence, and subsurface materiality in Colombia

open access: yesJournal of the Royal Anthropological Institute, Volume 31, Issue 2, Page 353-375, June 2025.
Abstract This article focuses on subsurface materiality to explore how small‐scale gold miners in Colombia navigate formal politics. In much critical research, the underground appears as a space of great developmentalist ambition, whose resources enable corporate expansion and bureaucratic rule.
