Differential responses of soil C, N, and P ecological stoichiometric characteristics to different configurations of edge-locked forests in the Kubuqi Desert

open access: yesFrontiers in Plant Science
As a vital component of the desert ecological protection system, the edge-locked forests of the Kubuqi Desert play a crucial role in mitigating wind erosion, stabilizing sand, maintaining soil and water, and restricting desert expansion.

A Two‐Protein Chemoreceptor Complex Regulates Oxygen Thresholds in Bacterial Magneto‐Aerotaxis

open access: yesAdvanced Science, EarlyView.
Magnetotactic bacteria align with Earth's magnetic field, helping them migrate toward low‐oxygen environments. This study reveals how Magnetospirillum gryphiswaldense uses a specialized flavin adenine dinucleotide (FAD)‐dependent chemoreceptor, composed of two interacting proteins, for precise navigation in oxygen gradients.

Integrative Single‐Cell Analysis Reveals Iron Overload‐Induced Senescence and Metabolic Reprogramming in Ovarian Endometriosis‐Associated Infertility

open access: yesAdvanced Science, EarlyView.
Iron overload in ovarian endometriosis (OE) disrupts follicular function and contributes to infertility. This study maps iron‐induced cellular changes using single‐cell and spatial transcriptomics, revealing senescence phenotypes in OE patients and mouse models. Similar patterns are observed in aging ovaries, highlighting iron metabolism as a potential

Restoring arid ecosystems: the synergistic benefits of fly ash and bentonite soil amendments

open access: yesFrontiers in Environmental Science
Fly ash and bentonite, two abundant industrial by-products in China, offer promising potential for ecological restoration in arid regions. In this study, we conducted a factorial pot experiment with 24 treatment combinations (6 fly ash levels: F0–F5 = 0 ...

Hosts and Commensal Bacteria Synergistically Antagonize Opportunistic Pathogens at the Single‐Cell Resolution

open access: yesAdvanced Science, EarlyView.
In the tripartite‐species model, Drosophila larvae stimulate lactate production through excreting digestion enzymes. S. marcescens population senses a cue of lactate and tends to diverge into virulent and reduced virulence subclusters with remarkable heterogeneity to metabolize carbon metabolism and counter colonization resistance, giving a fitness ...
