Illuminating the Arctic: Unveiling seabird responses to artificial light during polar darkness through citizen science and remote sensing

Remote Sensing in Ecology and Conservation, EarlyView.
Artificial light at night (ALAN) has global impacts on animals, yet its effects in polar regions remain underexplored. In this study, we analyzed a decade of citizen science data on seabird occurrences in Longyearbyen, using remote sensing data to assess the impact of ALAN during the polar night.

Update on the German and Australasian Optical Ground Station Networks

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT Networks of ground stations designed to transmit and receive at visible and infra‐red wavelengths through the atmosphere offer an opportunity to provide on‐demand, high‐bandwidth, secure communications with spacecraft in Earth orbit and beyond. This work describes the operation and activities of current free space optical communications (FSOC)

Balancing Immediate Relief and Resilience: Centring Local Voices for Disaster Aid and Capacity Building in Climate‐Conflict Vulnerable Communities

Sustainable Development, EarlyView.
ABSTRACT Climate change exacerbates fragility and security risks; however, the intersectional vulnerabilities arising from climate and conflict in fragile regions remain insufficiently studied, particularly from local perspectives. While development practices have increasingly shifted towards capacity‐building approaches, traditional aid distribution ...

Differences in the suitability of published honey bee (Apis mellifera) reference genes between the African subspecies Apis mellifera scutellata and European derived Apis mellifera

Molecular Ecology, EarlyView., 2023
Abstract Quantitative real‐time polymerase chain reaction (qPCR) is a method widely used to determine changes and differences in gene expression. As target gene expression is most often quantified relative to the expression of reference genes, the validation of suitable reference genes is of critical importance.

EnEx-RANGE - Robust autonomous Acoustic Navigation in Glacial icE

EPJ Web of Conferences, 2017
Within the Enceladus Explorer Initiative of the DLR Space Administration navigation technologies for a future space mission are in development. Those technologies are the basis for the search for extraterrestrial life on the Saturn moon Enceladus.

Space Economy and Sustainability: A Systematic Review

Sustainable Development, EarlyView.
ABSTRACT The space economy is booming thanks to the increasing investment of government agencies, private companies, and venture capitalists. From the beginning of the New Space era, the array of actors involved in the development of technologies for extra‐terrestrial activities has increased, as well as the downstream applications that foster ...

A Simplified Model for the Forced Libration of Icy Moons with Subsurface Oceans: Application to Enceladus and Mimas [PDF]

arXiv
In this work, we investigate a minimalist model capable of accurately replicating the forced librations of an icy moon with a subsurface ocean. The model holds potential to predict the presence of a subsurface ocean through analysis of longitudinal librations.

Viability of the Early JUICE Flyby Trajectories to Confirm Ocean Existence at Ganymede

The Planetary Science Journal
Ganymede is the largest moon in our solar system, and unique in producing its own magnetic field, as well as possibly possessing a subsurface ocean. The data analysis from the Galileo spacecraft provided two models for the internal field—a dipole and ...

Science Triggers and Situational Interest in Everyday Family Life

Journal of Research in Science Teaching, EarlyView.
ABSTRACT Interest in science is critical for science learning. The family plays a major role in supporting the development of children's interest in science by eliciting and fostering interest and engagement with science content and practice. This study characterizes triggers for interest in science in everyday family life and measures the duration of ...
