Orbit design for future SpaceChip swarm missions in a planetary atmosphere [PDF]

, 2012
The effect of solar radiation pressure and atmospheric drag on the orbital dynamics of satellites-on-a-chip (SpaceChips) is exploited to design equatorial long-lived orbits about the oblate Earth.

Amphibole's Influence on Mid‐Lithosphere Discontinuity: Insights From Electrical Conductivity

Geophysical Research Letters
The potential role of metasomatism‐induced hydrated layers, such as amphibole, in causing the mid‐lithospheric discontinuities (MLDs) has been widely debated.

Experimental study on influences of surface surcharge on existing shield tunnels buried in soft and hard soils

Yantu gongcheng xuebao, 2019
To explore the influences of surface surcharge on the existing shield tunnels buried in soft and hard soil strata, the scaled model tests on the interaction between shield tunnels and strata are carried out, and the tunnel deformation, earth pressure and

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

A diamond-bearing core-mantle boundary on Mercury

Nature Communications
Abundant carbon was identified on Mercury by MESSENGER, which is interpreted as the remnant of a primordial graphite flotation crust, suggesting that the magma ocean and core were saturated in carbon.

The human gut microbiome across the life course

FEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

FEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

High-pressure and temperature investigation of silicic acid ± water with implications for the ice polymorphism, lunar moganite and diamonds growth media

Progress in Earth and Planetary Science
The polymorphism of ice has been widely investigated over the last decades, and the results were found to be applicable over a wide range of terrestrial and extraterrestrial environments with recent findings also among the mineral inclusions entrapped in

Adsorption behavior of H2 in quartz silt-pores at high temperature and pressure

AIP Advances, 2023
To understand the storage and transport of H2 in the Earth’s interior, the adsorption behaviors of H2 in the slit-like pore of quartz under different conditions were calculated by the grand canonical Monte Carlo method.
