Recent Tectonic Deformation of the Lunar Farside Mare and South Pole–Aitken Basin

The Planetary Science Journal
The timing and scale of lunar tectonism provide a crucial insight into the geologic evolution of Earth’s Moon. Within the nearside lunar maria, wrinkle ridges formed during and after the emplacement of the mare basalts as a result of subsidence-induced ...

A Low‐Power Radioisotope XRF Spectrometer for Detection of Light Elements on Planetary Missions

X-Ray Spectrometry, EarlyView.
ABSTRACT Current X‐ray spectrometers for in situ geochemical analysis on planetary missions typically rely either on X‐ray tubes, which demand electrical power and add mass and thermal complexity, or on alpha particle X‐ray spectrometers (APXS) that use rare 244Cm$$ {}^{244}\mathrm{Cm} $$ sources, and come with severe concerns on radiation safety and ...

Multiplying Elements of Fragmentation? Polycentrism, the Launcher Crisis and the Future of Europe in Space

Global Policy, EarlyView.
ABSTRACT This article explores the current controversies surrounding the European Ariane launcher and its implications for the future of European space governance. The Ariane program, historically a symbol of European technopolitical integration, faces mounting challenges due to delays, rising costs and increasing competition from private actors like ...

Punchline with(out) purpose: Integrating research on instructional humour and seductive details

British Journal of Educational Psychology, EarlyView.
Abstract Introduction We integrated research on instructional humour and seductive details to investigate when affiliative course‐related humour is effective or rather ineffective for learning. We assumed that instructional humour without a cognitive function (irrelevant humour) would have detrimental effects on learning performance resembling the ...

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

Planetary Soil Simulant Characterisation: NU-LHT-2M Study Case to Support Oxygen Extraction Lab Tests with a Low-Temperature Carbothermal Process

Aerospace
Since the landing on the lunar surface, the lunar regolith has begun to interact in different ways with landed elements, such as the wheels of a rover, astronaut suits, drills, and plants for extracting oxygen or manufacturing objects.

Transient Hyperparathyroidism and Severe Intrauterine Osteopenia Linked to Novel Homozygous TRPV6 Deletion

Clinical Endocrinology, EarlyView.
ABSTRACT Context Placental calcium (Ca2+) transport is essential for foetal bone mineralisation and development, as well as for Ca2+ homoeostasis. Rare mutations in transient receptor potential vanilloid (TRPV) 6 of the infant cause insufficient maternal‐foetal Ca2+ transport through the placenta.
