Optimal Design of High-Power Density Medium-Voltage Direct Current Bipolar Power Cables for Lunar Power Transmission

Aerospace
Power systems on the lunar surface require power lines of varying lengths and capacities to connect generation, storage, and load facilities. These lines must be designed to perform efficiently in the harsh lunar environment, considering factors such as ...

Pervasive impact modification of pristine lunar clasts

Nature Communications
Lunar rock fragments, particularly those deemed pristine, have long been considered vital records of the Moon's formation and magmatic evolution. These fragments were thought to have largely escaped the Moon's intense impact history, offering a window into the early lunar crust. However, the concept of "pristine" is increasingly debated, as traditional

Spectrum of Hypogonadism and Its Management in Adolescents With Prader‐Willi Syndrome: A Retrospective Cohort Study Over 35 Years

Clinical Endocrinology, EarlyView.
ABSTRACT Context Adult data indicate that hypogonadism is underdiagnosed and undertreated in Prader‐Willi Syndrome (PWS). Objectives We aimed to describe the spectrum of pubertal development, and the diagnosis and treatment of hypogonadism in paediatric/adolescent patients with PWS. Design/Patients A retrospective cohort study of patients with PWS aged

Advancing conservation breeding programs for marine invertebrates

Conservation Biology, EarlyView.
Abstract In the face of ecosystem change and biodiversity loss caused by climate change and other stressors, conservation breeding, or captive breeding, with the aim of reintroduction for wild population recovery, is an emerging tool for preventing species’ extinction and rehabilitating ecosystems.

Micrometeoroid Impacts: Dual Pathways for Iron Reduction and Oxidation on Lunar and Asteroidal Surfaces

The Astrophysical Journal
Nanophase metallic iron (npFe ^0 ) is a key indicator of space weathering on the lunar surface, primarily attributed to solar wind irradiation and micrometeoroid impacts.

Analysis of Sea Turtle Bycatch by Andalusia Pelagic Longline Fleet in the Northeast Atlantic

Fisheries Oceanography, EarlyView.
ABSTRACT The Northeast Atlantic is one of the most crucial foraging grounds for juvenile loggerhead (Caretta caretta) and leatherback turtles (Dermochelys coriacea), while also serving as an important fishing area for the Andalusia surface longline fishery. The main aim of present study is to assess the sea turtle interaction with the Andalusia pelagic

Ejecta Blankets at Small Craters on the Moon

The Planetary Science Journal
Impact-derived ejecta covers most of the lunar surface, originating from recent impacts through to the beginning of the geologic record. Despite how common ejecta is, accurate measurements of ejecta thickness are difficult to obtain, and existing ...

Mapping Escolar (Lepidocybium flavobrunneum) in Motion: Oceanographic Forces Shaping Its Habitat in the Southwestern South Atlantic, With Insights From Fishers' Perceptions

Fisheries Oceanography, EarlyView.
ABSTRACT Lepidocybium flavobrunneum [Smith, 1843], commonly known as escolar, is a large pelagic species, important for global and local fisheries, particularly in the southwestern South Atlantic Ocean (SWAO), where it constitutes a significant portion of the catch.
