The Promise of Solid Lubricants for a Sustainable Future

open access: yesAdvanced Materials, EarlyView.
Lubricants are vital for technology, saving energy and resources. The industry seeks sustainable solutions beyond fossil fuels. Solid lubricants offer extremely low friction and reduce environmental impact, especially in harsh conditions. Can these solids truly replace liquid lubricants, or are they limited to extreme applications?

Laboratory Study of Dust Mobilization on Airless Planetary Bodies in the Solar Wind Plasma

open access: yesThe Planetary Science Journal
Dust charging, and the subsequent mobilization and transport, have been suggested to explain a number of unresolved and unusual features observed on airless planetary surfaces.

Tumor‐Derived CDC37 Inhibits Antigen Cross‐Presentation in Dendritic Cells and Impairs Anti‐Tumor Immunity in Breast Cancer

open access: yesAdvanced Science, EarlyView.
Extracellular vesicle (EV)‐packaged CDC37 are released from TMBhiCTLlo breast cancer cells with high CDC37 expression, and internalized into endo/phagosomes of dendritic cells (DCs). Within these compartments, CDC37 locked HSP90–antigen complex, preventing antigen release into the cytosol.

Cosmic Dust as a Prerequisite for the Formation of Complex Organic Molecules in Space?

open access: yesThe Astrophysical Journal
In cold, dense astrophysical environments dust grains are mixed with molecular ices. Chemistry in those dust/ice mixtures is determined by diffusion and reaction of molecules and radicals.

Study of the Extraterrestrial Materials in Antarctica (VI) : Cosmic Dust Collected from the Glacier Ice of the Meteorite Ice Field, Yamato Mountains

open access: yesAntarctic Record, 1976
Black spherical microparticles, glassy microparticles and other irregular-shaped particles were collected from the glacier ice, sampled in December 1974, of the Meteorite Ice Field, Yamato Mountains.

A Multi‐Purpose Heliophysics L4 Mission

open access: yesSpace Weather, 2021
The Earth‐Sun Lagrangian point 4 is a meta‐stable location at 1 AU from the Sun, 60° ahead of Earth's orbit. It has an uninterrupted view of the solar photosphere centered on W60, the Earth's nominal magnetic field connection to the Sun.

ARL3 Enhances ERα Stability via USP10 Deubiquitination to Promote Endocrine Resistance and Drive Mitochondrial Metabolic Reprogramming in HR+ Breast Cancer

open access: yesAdvanced Science, EarlyView.
This study identifies ADP‐ribosylation factor‐like protein 3 (ARL3) as a novel chaperone that stabilizes estrogen receptor α (ERα) in breast cancer. ARL3 promotes tumor growth by recruiting USP10 to remove ubiquitin chains from ERα, preventing its degradation.

Effect of Silicon‐Based Electrolyte Additive on the Solid‐Electrolyte Interphase of Rechargeable Mg Batteries

open access: yesAdvanced Science, EarlyView.
In this work, a silicon‐based electrolyte additive is introduced to condition the interfaces through an activation process. Symmetric cell studies with the additive show a five‐fold decrease in interfacial resistance and over 1200 h of stable Mg plating/stripping overpotential. The full cells with Mo6S8 cathodes exhibit excellent cycling stability over

The cosmic dust rate across the Universe [PDF]

open access: yes, 2017
We investigate the evolution of interstellar dust in the Universe by means of chemical evolution models of galaxies of different morphological types, reproducing the main observed features of present-day galaxies.

Red Blood Cell‐Derived Exosomal miR‐93‐5p Promotes Lung Cancer Progression through PTEN Suppression

open access: yesAdvanced Science, EarlyView.
Red blood cell (RBC)‐derived exosomal miR‐93‐5p is elevated in lung cancer patients and correlates with poor outcomes. Exosomal miR‐93‐5p suppresses PTEN in cancer cells, enhancing proliferation, migration, and invasion. In mouse models, therapeutic inhibition with ASO‐miR‐93 5p reduces tumor growth, highlighting a bidirectional tumor‐RBC‐tumor axis ...
