Imaging quantum melting in a disordered 2D Wigner solid.

Two-dimensional strongly interacting electrons crystalize into a solid phase known as the Wigner crystal at low densities and form a Fermi liquid at high densities. At intermediate densities, the two-dimensional solid evolves into a strongly correlated liquid phase around a critical density. We observed this quantum melting of a disordered Wigner solid in bilayer molybdenum diselenide (MoSe) using a noninvasive scanning tunneling microscopy imaging technique.

District ammonium-to-nitrate ratios change soil N dynamics and shape inverse patterns of resource acquisition strategy and biomass production of four urban greening trees.

Ammonium nitrogen (NH) and nitrate nitrogen (NO), the primary soil accessible nitrogen (N) forms for most plants, can affect plant ecophysiology and biomass production in different ways. Plants typically exhibit varying capacities for uptake and assimilation of the two N forms, leading to differences in the ecological strategies and niches within ecosystem. Recently, variations in atmospheric NH/NO deposition have severely threatened plant growth and ecosystem functions, especially in urban green spaces.

Continuous Abrupt Vegetation Shifts in the Global Terrestrial Ecosystem.

Previous studies have primarily focused on single abrupt shifts; however, the actual ecosystem will experience continuous abrupt shifts (CAS), including different directions shifts (DDS) and same direction shifts (SDS). The patterns and drivers of these CAS remain unclear. We examined the patterns of the DDS and SDS by two vegetation datasets and then tested climate drivers comprising atmospheric temperature (MAT), atmospheric precipitation (MAP), soil temperature (ST) and soil water content (SW); finally, hysteresis effects were examined with reference to principal drivers.

Creating Single Atomic Coordination for Hypoxia-Resistant Pyroptosis Nano-Inducer to Boost Anti-Tumor Immunotherapy.

General synthesis and mechanical understanding of type I nano-photosensitizers are of great importance for hypoxia-resistant pyroptosis inducers. Herein, a simple solvothermal treatment is developed to convert non-photosensitive small molecules (hemin) into uniform carbon nanodots (HNCDs) with strong type I photodynamic activity and red fluorescence emission. These HNCDs inherit the single atomic Fe-N center of hemin while creating sp-hybridized carbon surroundings, which synergistically modulated the energy level and electron transfer for converting the type II photodynamic process to type I.

Association of branched-chain amino acids and risk of three urologic cancers: a Mendelian randomization study.

Background: Multiple studies suggest a plausible connection between urologic cancers and branched-chain amino acids (BCAAs) breakdown metabolic enzymes. Nevertheless, there is scarce exploration into the variations in circulating BCAAs. In our research, we utilize bidirectional, two-sample Mendelian randomization (MR) analysis to predict the link between BCAAs levels and three distinct types of urological tumors.

ERK activation dynamics in maturing oocyte controls embryonic nuclear divisions in Caenorhabditis elegans.

ERK activity oscillates between sustained activation during oocyte formation and transient inactivation during oocyte maturation, fertilization, and early embryogenesis. Consequences of ectopic ERK activity upon oocyte maturation and in early embryogenesis are unknown. We show, in Caenorhabditis elegans, that ectopic ERK activity upon oocyte maturation (metaphase I oocytes) results in embryos with abnormalities in nuclear divisions leading to embryonic death.
