Asuka 12236 more primitive than Paris: Clues given by their Infrared and Raman micro‐spectroscopy signatures

open access: yesMeteoritics &Planetary Science, Volume 60, Issue 8, Page 1851-1860, August 2025.
Abstract Carbonaceous chondrites are meteorites originating from undifferentiated objects of the Solar System, which may retain signatures of primitive matter. Here, we present a comparative study between two CM chondrites Asuka 12236 and Paris, both considered among the most primitive in the carbonaceous chondrite meteorite collection.

Seismic Velocities of Subducted Serpentinites Through the Lizardite‐Antigorite Transition

open access: yesGeophysical Research Letters, Volume 52, Issue 13, 16 July 2025.
Abstract The mineralogical transition (lizardite to antigorite) occurring in serpentinites dragged down in subduction zones depends on the metamorphic pressure and temperature conditions. The seismic Vp/Vs ratio is useful for distinguishing serpentinites from other mantle rocks. To understand the effects of the metamorphic conditions and the associated

The Global Health Dimensions of Asbestos and Asbestos-Related Diseases

open access: yesAnnals of Global Health, 2016
The Collegium Ramazzini (CR) reaffirms its long-standing position that responsible public health action is to ban all extraction and use of asbestos, including chrysotile. This current statement updates earlier statements by the CR with a focus on global

Estimating past inhalation exposure to asbestos: a tool for risk attribution and disease screening [PDF]

open access: yes, 2017
Introduction: Late presentation is common in mesothelioma. Reliable assessment of past exposure to asbestos is a necessary first step for risk attribution and for the development of a future screening programme. Such a programme could maximise access

Seismicity to the South of the Louisville Ridge‐Tonga Trench Collision Zone: New Insight Into Processes Controlling Seismic Gaps and Subduction Erosion

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 7, July 2025.
Abstract The Louisville seismic gap associated with the subduction of the Louisville Ridge (LR) along the Tonga‐Kermadec trench is a globally prominent feature. Due to the lack of near‐field seismic monitoring, the earthquake potential and seismic behavior in this region have long been an enigma.

Dose-Response Relationships in Expression of Biomarkers of Cell Proliferation in Assays and Inhalation Experiments

open access: yesDose-Response, 2004
Asbestos is a group of naturally occurring mineral fibers which are associated in occupational settings with increased risks of malignant mesothelioma (MM), lung cancers, and pulmonary fibrosis (asbestosis).
