The Kuroshio regulates the air-sea exchange of PCBs
Air-sea diffusion flux is the main source of PCBs in the open ocean (Jurado et al., 2007). The oceanic biological pump, current advection, and eddy diffusion affect the distribution of PCBs in the...
View ArticleExperimental constraints on the oxidation state of early magma on the Earth
The link between a planetary interior and its surface is a key to understanding the formation process of the surface environment of the planet. The distribution of ferrous (Fe2+) and ferric (Fe3+) iron...
View ArticleHighly oxidizing magma of the early Earth
Elucidating the atmosphere and surface environment of the early Earth, especially before the origin of life, is a key to understanding the habitability of the Earth. The atmosphere of terrestrial...
View ArticleExperimental constraints on the viscosity of the Earth’s inner core
Although many geodynamical mechanisms have been proposed regarding the origin of the observed complex structure of Earth’s inner core, no clear consensus has been reached. This is partly owing to the...
View ArticleEndocrine disruption in seals by environmental contaminants
In this study, the ability of bisphenols (BPs) and hydroxylated polychlorinated biphenyls (OH-PCBs) to activate estrogen receptor α and β subtypes (bsERα and bsERβ) in Baikal seals (Pusa sibirica) was...
View ArticleOrganohalogen contamination impact on the health of Baltic Atlantic salmon
The Baltic Sea Atlantic salmon (Salmo salar) consists of both wild and hatchery-reared fish. As these salmon forage for food, they migrate through various areas of the Baltic Sea and are exposed to a...
View ArticleOrganophosphorus flame retardants induce malformations in avian embryos
Tris(2-chloroisopropyl) phosphate (TCIPP) is one of the organophosphorus flame retardants that has been detected in the environment, and in the eggs, feathers, and liver of birds. Early developmental...
View ArticleA new approach to predicting the binding properties of forever chemicals...
Per- and polyfluoroalkyl substances (PFAS) are widely used in various products as water-repellents and stain-resistant coatings. PFAS are called “Forever chemicals” due to their exceptional thermal and...
View ArticleInternational publication of scientific book on the status of coral reefs in...
Coral reef ecosystems are among the highest biodiverse and productive ecosystems on the Earth. It is reported that 500 million people worldwide benefit from coral reef ecosystems in terms of food,...

A spherically shaped particle of synthetic hectorite (denoted as Na-HEC) was ion-exchanged with a divalent Cu(II) complex, [Cu(SS-oxa)]2+ (SS-oxa = SS-2,2′-isopropylidene-bis(4-phenyl-2-oxazoline))....
View ArticleOlivine unlocks the secrets of the Moon’s interior
Olivine is the earliest mineral to crystallize from basaltic magma, and accurate knowledge of olivine/melt partition coefficients (DOl-melt) for first-transition row elements (FTREs) Ga and Ge, is...
View ArticleTransient creep in olivine controls post-seismic deformation
Geodetic observations reveal that the deformation of the crust and upper mantle after a great earthquake continues for decades (Fig.1). Viscosities of the upper mantle estimated from early post-seismic...
View ArticleHigh-pressure silica mineral in the deep Earth is anhydrous
In the Earth’s subduction zones, water is transported into the deep mantle by nominally anhydrous minerals (NAMs) and water-bearing minerals in oceanic plates that react with seawater. Therefore,...
View ArticleA Garnet-rich Lunar Mantle?
Our present-day Moon has an interior structure containing a central metallic core, overlain by a mantle comprised of minerals such as olivine and pyroxene (e.g. Ol+Px mantle) underneath a shell of...
View ArticleFirst-principles investigations of the polysomatism of antigorite under pressure
Antigorite is a type of serpentine, which is the most abundant hydrated mineral on the Earth. It is widely believed that this mineral is the main carrier of water deep into the Earth in subducting...
View ArticleChlorinated flame retardants affect avian embryonic development
Short-chain chlorinated paraffins (SCCPs) were listed under the category of globally controlled persistent organic pollutants (POPs) by the Stockholm Convention in 2017. However, SCCPs toxicity,...
View ArticleGrain boundaries weaken in planetary interiors
Mantle convection and associated plate tectonics of planets like the Earth are governed by the deformation of mantle rocks. This deformation occurs through the motion of defects in the crystal lattices...
View ArticleAccurately estimating the mass of meso- and microplastic particles
Plastic particles, which are known as “transport vectors” of toxic chemicals, have leaked from land to the ocean. In particular, mesoscale (5-25 mm) and microscale (<5 mm) plastic (MMP) particles...
View ArticleWater delivered to the mantle by aluminum enriched hydrated slabs?
Dense Hydrous Magnesium Silicates (DHMSs) are generally considered as primary water carriers from the shallow lithosphere to the deep mantle transition region (MTR; 410–660 km in depth). Among DHMSs,...
View ArticleGlobal Anthropogenic Fingerprints Suggest the Anthropocene Began in the 1950s
Based on stratigraphic records, there have been attempts to identify when the first fundamental changes brought about by humans appeared in the Earth system, but researchers have been divided on the...
