Using the transit of Venus to probe the upper planetary atmosphere [PDF]

open access: yes, 2015
The atmosphere of a transiting planet shields the stellar radiation providing us with a powerful method to estimate its size and density. In particular, because of their high ionization energy, atoms with high atomic number (Z) absorb short-wavelength ...

Circulating Metabolites Treat Human TMJ‐OA by Eliminating Senescent Chondrocytes via the C1QBP/C1q/p14ARF Axis

open access: yesJournal of Extracellular Vesicles, Volume 15, Issue 2, February 2026.
ABSTRACT Temporomandibular joint osteoarthritis (TMJ‐OA) is a progressive degenerative disorder, for which therapeutic interventions remain limited. The disruption of metabolic homeostasis plays a critical role in the pathogenesis and advancement of TMJ‐OA.

Laboratory evaluation of microwave absorption properties under simulated conditions for planetary atmospheres [PDF]

open access: yes
The microwave absorbing properties of gaseous sulfuric acid (H2SO4) under Venus atmospheric conditions are investigated. The results are applied to measurements from Mariner 5, Mariner 10, and Pioneer/Venus Radio Occultation experiments, to determine ...

Raman Spectroscopic Analysis and In Situ Heating Experiments on Adranosite Minerals

open access: yesJournal of Raman Spectroscopy, Volume 57, Issue 2, Page 343-359, February 2026.
This study provides the first detailed Raman spectroscopic characterization of rare ammonium sulfates adranosite, iron‐rich adranosite, and adranosite‐(Fe) from volcanic and coal‐fire environments. Distinct spectral features reveal compositional differences and structural effects of Fe substitution.

Origin of the Bulge Topography Within Caloris Basin, Mercury

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract Caloris basin on Mercury has a massive circular bulge topography imprinted with unique fault sets. A variety of deformational processes have been proposed to have influenced their formation, including both global contraction and basin evolution, as well as the deposition and weight of the volcanic infill.

Disruption of ATP Synthase Spatiotemporal Organization, Ca2+ Dynamics, and Contractile Function in Senescent Cardiomyocytes

open access: yesAging Cell, Volume 25, Issue 2, February 2026.
Enhanced ATP hydrolysis, ΔΨm flickering, and destabilized ATP synthase dimers collectively reduce ATP availability in senescent cardiomyocytes. This energy deficit is associated with disrupted Ca2⁺ dynamics and contractility. ABSTRACT Heart disease is the leading cause of death in the elderly population.

Come from away: Reconstructing a long‐range migratory flight of spruce budworm moths to Newfoundland, Canada Venues de loin : reconstitution d'un vol migratoire de longue distance de tordeuses des bourgeons de l'épinette vers Terre‐Neuve, au Canada

open access: yesEcological Entomology, Volume 51, Issue 1, Page 41-58, February 2026.
Lagrangian atmospheric models were used in conjunction with ecophysiological factors to reconstruct the path and meteorological conditions of a long‐range migration flight of spruce budworm moths to Newfoundland, Canada. Moths travelled under high winds and warm temperatures that favoured their migratory flight until encountering cooler temperatures ...
