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 ...

Dissimilatory phosphite oxidation (DPO), a microbial metabolism by which phosphite (HPO 32−) is oxidized to phosphate (PO 43−), is the most energetically favorable chemotrophic electron-donating ...

Root development is tightly controlled by light, and the response is thought to depend on signal transmission from the shoot. Here, we show that the root apical meristem perceives light independently ...

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 ...

The brain is a complex system operating out of equilibrium with time-irreversible dynamics. Existing measures of irreversibility cannot identify which multivariate interactions display particularly ...

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 ...

This study changes our view of Alzheimer’s disease (AD) initiation and progression. Mutations promoting cerebral beta-amyloid (Aβ) deposition guarantee rare genetic forms of AD. Thus, the prevailing ...

Arbuscular mycorrhiza (AM) is a mutualistic symbiosis formed between land plants and fungi of the phylum glomeromycotina (1, 2). A hallmark of this alliance is the reciprocal exchange of nutrients: ...

Biomass-burning organic aerosol (s) (BBOA) not only significantly impact Earth’s climate by absorbing solar radiation but also generate excited triplet states (3 BBOA *) that react with other ...
