Calcium Solubility of Bridgmanite in Subducted Basalt in Earth's Lower Mantle

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The calcium solubility in bridgmanite and the resulting abundance of davemaoite under lower‐mantle pressure‐temperature conditions have been under debate following a recent report of extensive calcium dissolution in bridgmanite. We experimentally investigated the calcium solubility in bridgmanite in a basaltic composition at pressures up to ...

Electrical Conductivity of Hydrous Ultramafic Melts With Implications for Origin of Low Velocity Layer Atop of the 410 km Seismic Discontinuity

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Low‐velocity layers (LVLs) above the 410‐km discontinuity are commonly attributed to partial melt generated by dehydration melting when hydrous mantle transition‐zone material rises into the upper mantle, where water solubility in nominally anhydrous minerals decreases.

Light Element Exsolution in Fe‐Si‐C‐(H) System: A Mechanism for Powering Mercury's Early Core Dynamo

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Mercury is one of the few terrestrial planets in the solar system with a magnetic field, yet the energy source to power its core dynamo remains unclear to date. Si, C, and possibly H are the top candidate light elements for its liquid core. Here, we showed experimentally that Si, C, and H in Fe‐Si‐C and Fe‐Si‐C‐H liquids share a simultaneous ...

Estimating Uncertainty of PMW‐Based Convective Fraction Product

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract Convective precipitation plays a crucial role in the Earth's hydrological cycle, vertical thermodynamic transport, and natural weather hazards. While satellite passive microwave (PMW) observations offer broad spatial coverage essential for global precipitation monitoring, uncertainties in PMW‐derived precipitation class (i.e., regime) remain ...

Development of the Human Incus With Special Reference to the Detachment From the Chondrocranium to be Transferred into the Middle Ear [PDF]

Anatomical Record, 2018
The mammalian middle ear represents one of the most fundamental features defining this class of vertebrates. However, the origin and the developmental process of the incus in the human remains controversial. The present study seeks to demonstrate all the

A new technique to find the facial nerve and recess by using the short process of the incus and the spine of Henle as landmarks: incus-spine angle [PDF]

Acta Oto-Laryngologica, 2018
Precise techniques to find the facial nerve (FN) and recess are lacking. We aimed to define incus-spine and incus-FN angles which can be used to localize the FN and recess during mastoidectomy. Thirty adult cadaveric temporal bones were studied.

Early development of the malleus and incus in humans [PDF]

Journal of Anatomy, 2016
It is widely accepted by developmental biologists that the malleus and incus of the mammalian middle ear are first pharyngeal arch derivatives, a contention based originally on classical embryology that has now been backed up by molecular evidence from ...
