The carbon isotopic composition of atmospheric CH 4 (δ13 C CH4) is a powerful tool for tracking the sources and sinks of atmospheric CH 4. Different CH 4 sources have distinctive δ 13 C CH4 values: ...

Many cities seek to alleviate extreme heat via planting trees. However, the cooling achieved by such programs is debated because previous analyses address scales much smaller than the whole-city scale ...

The multiple challenges of managing large-scale PV wastes demand a proactive approach; the costs of being underprepared or unprepared far outweigh those of early preparation. We must anticipate the ...

Understanding how ecosystems respond to ubiquitous microplastic (MP) pollution is crucial for ensuring global food security. Here, we conduct a multiecosystem meta-analysis of 3,286 data points and ...

The apical hook protects cotyledons and shoot apical meristem from injuries during seedling emergence from the soil. Auxin plays a key regulatory role in hook formation. Recently, a noncanonical auxin ...

Growing evidence has highlighted the role of small RNAs (sRNA) as trafficking effectors for cross-kingdom RNA interference (RNAi) between interacting organisms. Yet, it remains unknown whether ...

During arbuscular mycorrhiza (AM) symbiosis AM fungi form tree-shaped structures called arbuscules in root cortex cells of host plants. Arbuscules and their host cells are central for reciprocal ...

Quantum amplification enables the enhancement of weak signals and is of great importance for precision measurements, such as biomedical science and tests of fundamental symmetries. Here, we observe a ...

Ecological divergence without geographic isolation, as an early speciation process that may lead finally to reproductive isolation through natural selection, remains a captivating topic in ...

Sexual dimorphism in immune responses is well documented, but the underlying mechanisms remain incompletely understood. Here, we identified a subset of corticotropin-releasing hormone (CRH) neurons ...

Genome integrity is paramount for gametes. Paradoxically, during the production of gametes, programmed DNA double-strand breaks (DSBs) are generated in the meiotic prophase and are repaired to ...

Protein fatty acylation, along with other types of protein lipidation (e.g., cysteine prenylation), dramatically alters protein hydrophobicity and behavior, regulating trafficking, localization, as ...
