Navigating challenges in prosthodontic rehabilitation after long‐term delay following fibula free flap reconstruction with a unique overlay removable prosthesis and large vertical dimension increase

Journal of Prosthodontics, EarlyView.
Abstract This case report highlights the experience of one maxillofacial surgical patient who delayed prosthodontic treatment for 7 years as they saved to self‐fund access to a subsidized prosthodontic service. Without the benefit of a restored opposing dentition for a prolonged period of time, maxillary occlusal plane disruption occurred as a ...

Visible, near‐, and thermal infrared spectra of asteroid Bennu samples: Relationship to and implications for remote sensing of carbonaceous asteroids

Meteoritics &Planetary Science, EarlyView.
Abstract Remote spectroscopy is used to characterize the mineralogy and infer the history of planetary bodies. Carbonaceous asteroids, such as B‐type (101955) Bennu, represent the earliest stages of planet formation. B types have a blue (negative) spectral slope and comprise <5% of asteroids.

Nanoscale space weathering features in mature lunar soil revealed by TEM and APT

Meteoritics &Planetary Science, EarlyView.
Abstract Space weathering significantly alters the optical, chemical, and structural properties of lunar regolith at micro‐ and nanoscales; yet detailed nanoscale variability within individual soils remains underexplored. Here we apply transmission electron microscopy (TEM) and atom probe tomography to four mineral grains (olivine, ilmenite, and two ...

ATHLETIC: An exoskeleton countermeasure exercise device for resistive and plyometric training in deep‐space missions

Experimental Physiology, EarlyView.
Abstract Prolonged exposure to weightlessness leads to loss of muscle and bone mass. Therefore, astronauts on board the International Space Station (ISS) currently perform mandatory daily exercises. ISS missions usually last 6 months, and future missions will become significantly longer when going, for example, to Mars.

A Century Later: Taxonomic Review of the Neotropical Genus Hyptiocheta Becker, 1922 (Diptera: Dolichopodidae), With Description of Three New Andean Species

Austral Entomology, Volume 65, Issue 3, August 2026.
ABSTRACT The previously monotypic Neotropical genus Hyptiocheta Becker, 1922 is reviewed. Hyptiocheta convexa Becker, 1922 is redescribed, and three new species are described and illustrated from South America: H. archaeoptera Quevedo, Soares & Lamas sp. nov. (Ecuador), H. chuspi Quevedo, Soares & Gutiérrez‐Bustamante sp. nov. (Peru) and H.
