Long‐Term Radiogenic Heating by Abortively Erupted Basalts Triggers 120 Ma Lunar Volcanism
Abstract The mantle source and formation mechanism of the recently discovered ∼120 Ma lunar volcanic glass beads (VGBs) in Chang'e‐5 samples remain elusive. By systematically comparing the compositions of ∼120 Ma VGBs with those of ancient Apollo VGBs, we propose a distinctive metasomatized mantle source characterized by low‐Ti but enriched in Na2O ...

A double click‐strategy combining copper‐catalyzed azide‐alkyne cycloaddition with (thia‐)Diels‐Alder reactions involving a reactive s‐cis‐constrained diene is reported. Three different one‐pot protocols (i.e., sequential or three‐component reactions) are proposed and offer valuable guidance for future applications.

The State of High‐Resolution Imaging of the Human Inner Ear: A Look Into the Black Box
High‐resolution imaging of the cochlea is challenged by numerous unique aspects of this organ, where sensorineural cells, crucial for hearing, are too small for conventional modalities like magnetic resonance imaging and computed tomography. This article reviews current imaging techniques, emerging technologies, and innovations aimed at improving ...

Algal community dynamics recorded by traditional monitoring and paleogenetic analysis of sediment DNA archives of experimentally fertilised and unmanipulated lakes in the IISD Experimental Lakes Area exposed synergistic effects of eutrophication and climate warming. ABSTRACT Lake ecosystems are increasingly impacted by eutrophication and climate change.

Thinking like a mountain: A land ethical approach to healthcare resource allocation
Abstract Human activity is now having a defining influence on global systems. The Anthropocene epoch requires revisiting our ethical presuppositions to understand our relationship to the earth's life support systems. The Land Ethic of Aldo Leopold proposes an ethic that is diachronic, holistic, and biocentric, in contrast to the synchronic ...

Phosphate elution from anion‐exchange membranes in soil analysis
Abstract Resin‐extractable phosphate (PO4‐P) is a widespread sink‐based measure of soil bioavailable phosphorus (P) used in biogeochemistry and soil fertility. However, acid elution of P may hydrolyze organic P and thus compromise measurement of PO4‐P. We evaluated sodium bicarbonate (NaHCO3) as an alternative to sulfuric acid (H2SO4) for PO4‐P elution.

By applying ecological niche theory, our work illustrates the foundational principles for understanding pathogen coinfection via the lens of resource and immune (apparent) competition. Coinfection, that is, within‐host species coexistence, necessitates a competition‐resistance trade‐off and that each parasite primarily affects the niche factor to which

Diurnal Regulation of SOS Pathway and Sodium Excretion Underlying Salinity Tolerance of Vigna marina
ABSTRACT Vigna marina (Barm.) Merr. is adapted to tropical marine beaches and has an outstanding tolerance to salt stress. Given there are growing demands for cultivating crops in saline soil or with saline water, it is important to understand how halophytic species are adapted to the saline environments.

From data to discovery: leveraging big data in plant natural products biosynthesis research
SUMMARY Plant natural products or specialized metabolites play a vital role in drug discovery and development, with many clinically important derivatives such as the anticancer drugs topotecan (derived from the natural alkaloid camptothecin) and etoposide (derived from the natural polyphenol podophyllotoxin).
