Recognition Mechanism of Serotonin by a G‐Quadruplex–Duplex Hybrid Aptamer

ABSTRACT Serotonin is a key neurotransmitter, and aptamer‐based tools using the 44‐nt Apt44 have been successfully developed for its in vitro and in vivo detection. Nevertheless, the structural basis of recognition by this aptamer remains unclear. Here, we report high‐resolution...

Topology‐Dependent Iso ‐Propanol Dehydration Pathway Over Zeolites

ABSTRACT The zeolite‐catalyzed dehydration of low‐carbon alcohols is a crucial step in the conversion of biomass‐derived compounds. Compared to methanol and ethanol, the propanol dehydration mechanism remains poorly understood. The core challenge lies in the high reactivity and s...

Global non-selfsimilar Riemann solutions for multi-dimensional scalar conservation laws with time-dependent nonlinear source terms

In this paper, we are concerned with the global non-selfsimilar Riemann solutions for the multi-dimensional scalar conservation law with a time-dependent nonlinear source term 𝑔 ⁡ ( 𝑡 , 𝑢 ) , where the Riemann-type initial data consist of two constant states separated by a curved...

ZIF‐8 Film Coatings Render Polymeric Device Surfaces Addressable by 1 H/ 129 Xe MRI

ABSTRACT Metal‐organic framework (MOF) films synergize molecular‐scale porosity with conformal surface chemistry on polymer substrates. We report a spectrally selective coating in which a ZIF‐8 film, seeded by a Zn(II)‐polydopamine (Zn‐PDA) interlayer on polytetrafluoroethylene (...

In-orbit test of the weak equivalence principle with atom interferometry

The weak equivalence principle (WEP) is a central pillar of general relativity. Its precise test with quantum systems in space offers a unique window onto new physics. Here, we report an in-orbit quantum test of the WEP. A dual-species ( 85 Rb/ 87 Rb) atom interferometer is reali...

High–spatiotemporal resolution deuterium metabolic imaging enables in vivo phenotyping of intra- and intertumoral heterogeneity

Intra- and intertumoral heterogeneities raise fundamental biological questions and have important implications for accurate cancer diagnosis, prognosis, and treatment. These heterogeneities reflect tumor complexity, including a pronounced diversity in metabolic phenotypes and pro...

Global Boundedness Induced by Asymptotically Non‐Degenerate Motility in a Fully Parabolic Chemotaxis Model with Local Sensing

ABSTRACT A fully parabolic chemotaxis model of Keller–Segel type with local sensing is considered. The system features a signal‐dependent asymptotically non‐degenerate motility function, which accounts for a repulsion‐dominated chemotaxis. Global boundedness of classical solution...

Keystone microbial isozyme enhances crustacean growth by utilizing L-citrulline

Under standardized rearing conditions, the genetically uniform “Keyong No. 1” swimming crab exhibits pronounced inter-individual variability in growth performance. While the gut microbiota is recognized contributors to crustacean growth, the specific microbes and mechanistic path...
