Rendezvous in Space: Tech Diplomacy and the Commercial Space Era—A Study of Rendezvous and Docking Technologies and Space Exploration Co‐Operation Since the Cold War

Global Policy, EarlyView.
ABSTRACT On‐orbit rendezvous and docking constitute one of the most technically challenging activities in the history of space activities. As space endeavours mature to crewed missions, space rendezous and docking technologies (RDT) emerge as an area of technological innovation critical to advances in future crewed space exploration.

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 ...

Lunar Impact Optimization

Natural celestial collision processes are rich in nonlinear dynamical characteristics and energy distribution patterns. In particular, the complex geomorphic phenomena produced by asteroid impacts on the Moon, such as crater formation, multi-ring basin structures, ejecta distribution patterns, and energy transfer at different scales, provide unique ...

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

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.

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.

Precious metal enrichment during impacts on the Moon

Communications Earth & Environment
Any sustained space exploration is likely to depend on the Moon and its resources. Understanding lunar mineral deposit potential, particularly for precious metals including Os, Ir, Ru, Rh, Pt, Pd, and Au (the platinum group elements, or PGE) and their ...

A fractal pattern of hierarchical genetic population structure in mixed stocks across fish segregated by dams revealed by genomic resources for curimba Prochilodus lineatus

Journal of Fish Biology, EarlyView.
Abstract Genomic resources, new microsatellite markers and a novel observation of a fractal pattern in the genetic population structure are presented for curimba, Prochilodus lineatus, a freshwater migratory model species of South America. Our main goals were to investigate the presence of mixed fish stocks and the effects of damming‐induced ...
