Potentially reduced fusogenicity of syncytin‐2 in New World monkeys

FEBS Open Bio, 2023
Syncytin‐2 is a membrane fusion protein involved in placenta development that is derived from the endogenous retrovirus envelope gene acquired in the common ancestral lineage of New World and Old World monkeys (OWMs).

Extracting phylogenetic dimensions of coevolution reveals hidden functional signals

Scientific Reports, 2022
Despite the structural and functional information contained in the statistical coupling between pairs of residues in a protein, coevolution associated with function is often obscured by artifactual signals such as genetic drift, which shapes a protein’s ...

Sluggish thermochemical basal mantle structures support their long-lived stability

Nature Communications
Large low shear-wave velocity provinces (LLSVPs) in the lowermost mantle are the largest geological structures on Earth, but their origin and age remain highly enigmatic.

The role of land weathering in carbon consumption and its impact on global carbon cycling since the Last Interglacial period

Scientific Reports
Atmospheric CO2 variations across glacial-interglacial cycles are tightly linked to oceanic and terrestrial carbon reservoirs, but the contribution of weathering remains poorly constrained.

Chang’e-6 farside anorthosites indicate hemispherically comparable magma ocean solidification

Nature Communications
Ferroan anorthosites (FANs) reflect the nature of the Moon’s crust formed during the late-stage lunar magma ocean (LMO). Remote sensing suggests a hemispheric dichotomy in crustal composition, with the farside anorthositic highlands being more magnesian ...

Refined weathering CO2 budget of the Tibetan Plateau strongly modulated by sulphide oxidation

Nature Communications
Estimation of net CO2 consumption by weathering in orogen is complicated as high erosion rate promotes competing processes of CO2 consumption (silicate weathering) and releasing (sulfuric acid (H2SO4) dissolution of carbonate).

The Influence of Reservoirs on Landslide Erosion

Remote Sensing
The evolution of the landslide erosion of bank slopes in reservoir regions is crucial for disaster prevention and mitigation in hydropower projects, and it is also an important topic to investigate the impact of anthropogenic activities on the ...

Long‐Term Radiogenic Heating by Abortively Erupted Basalts Triggers 120 Ma Lunar Volcanism

Geophysical Research Letters
The mantle source and formation mechanism of the recently discovered ∼120 Ma lunar volcanic glass beads (VGBs) in Chang'e‐5 samples remain elusive. By systematically comparing the compositions of ∼120 Ma VGBs with those of ancient Apollo VGBs, we propose
