Integrated MCDM framework for sustainable pharmacy supplier selection using pioneering criteria with fuzzy TOPSIS SVR and GRA
Abstract Supplier selection is indispensable across diverse industries, particularly in the pharmaceutical sector, due to its direct impact on health and safety. This underscores the necessity for the timely availability of high-quality products. This research aims to elevate the sustainability of pharmaceutical inventory management by introducing pioneering criteria for supplier evaluation. A groundbreaking methodology is proposed by seamlessly integrating TOPSIS-GRA within a fuzzy environment for sustainable supplier selection. The CFCS algorithm ensures precise defuzzification, addressing uncertainties in data representation. Additionally, SVR improves criteria weighting by capturing complex data patterns. This integrated approach enables a comprehensive supplier assessment, offering valuable insights to pharmaceutical decision-makers. Ultimately, it provides a robust framework for selecting suppliers aligned with sustainability principles and optimizing procurement practices.

Timing the escape of a photoexcited electron from a molecular cage
Abstract Charge transfer is fundamentally dependent on the overlap of the orbitals comprising the transport pathway. This has key implications for molecular, nanoscale, and quantum technologies, for which delocalization (and decoherence) rates are essential figures of merit. Here, we apply the core hole clock technique—an energy-domain variant of ultrafast spectroscopy—to probe the delocalization of a photoexcited electron inside a closed molecular cage, namely the Ar 2p 54s 1 state of Ar@C60. Despite marginal frontier orbital mixing in the ground configuration, almost 80% of the excited state density is found outside the buckyball due to the formation of a markedly diffuse hybrid orbital. Far from isolating the intracage excitation, the surrounding fullerene is instead a remarkably efficient conduit for electron transfer: we measure characteristic delocalization times of 6.6 ± 0.3 fs and ≲ 500 attoseconds, respectively, for a 3D Ar@C60 film and a 2D monolayer on Ag(111).

Wetland fragmentation associated with large populations across Africa
Abstract Wetlands provide essential ecosystem services in Africa, yet their extent and fragmentation remain poorly understood. Here we classify African wetlands at 10 m resolution, using seasonal composite imagery and a random forest algorithm. We estimate a total wetland area of 947,750 km² (10% of global wetlands), comprising 46% marshes, 25% swamps, 22% peatlands, 5% seasonal wetlands, and 2% mangroves. Wetland fragmentation is strongly associated with high population densities in countries such as Nigeria, Liberia, Guinea, Egypt, Algeria, and Kenya. African wetlands store an estimated 54 ± 11 Gt of carbon, surpassing Europe’s 12–31 Gt. If drained, they could release 260 MtC yr−¹, nearly ten times the carbon sequestration of pristine wetlands (27 MtC yr−¹). These findings provide a crucial foundation for sustainable wetland management and policy development.

Lipid Dysregulation in Sepsis: A Prognostic Marker for Mortality and Organ Dysfunction
Eomesodermin in conjunction with the BAF complex promotes expansion and invasion of the trophectoderm lineage
Abstract The T-box transcription factor (TF) Eomesodermin/Tbr2 (Eomes) is essential for maintenance of the trophectoderm (TE) lineage, but the molecular mechanisms underlying this critical role remain obscure. Here, we show in trophoblast stem cells (TSCs) that Eomes partners with several TE-specific TFs as well as chromatin remodellers, including Brg1 and other subunits of the BAF complex. Degron-mediated Eomes protein depletion results in genome-wide loss of chromatin accessibility at TSC-specific loci. These overlap with a subset of sites that lose accessibility following Brg1 inhibition, suggesting that Eomes acts as a “doorstop” controlling TSC chromatin accessibility. Eomes depletion also causes transcriptional misregulation of TSC maintenance and early differentiation markers. An additional subset of Eomes-dependent genes encode intercellular/matricellular interaction and cytoskeletal components, likely explaining the implantation defects of Eomes-null embryos. Thus, Eomes promotes TE lineage maintenance by sustaining trophectoderm-specific chromatin accessibility, while promoting the gene regulatory networks that modulate expansion and cell behaviour during implantation.

Photochemical synthesis of natural lipids in artificial and living cells
Abstract Lipid synthesis plays a central role in cell structure, signaling, and metabolism. A general method for the abiogenesis of natural lipids could transform the development of lifelike artificial cells and unlock new ways to explore lipid functions in living cells. Here, we demonstrate the abiotic formation of natural lipids in water using visible-light-driven photoredox chemistry. Radical-mediated coupling of hydrocarbon tails to polar single-chain precursors yields lipids identical to those enzymatically formed. Spatiotemporally controlled lipid generation promotes de novo vesicle formation, growth, and division. Lipid synthesis can be driven by RNA aptamers that specifically bind and activate photocatalysts, establishing a direct link between abiotic lipid metabolism and nucleic acid sequence. Light-mediated assembly of bioactive lipids can take place in living cells, triggering signaling events such as apoptosis and protein kinase C (PKC) activation. Our finding that photochemical lipid synthesis can be driven by simple genetic elements could be the starting point for developing protocells capable of Darwinian evolution. Additionally, the ability to generate specific membrane lipids in living cells with precise spatiotemporal control will advance studies on how lipid structure influences cellular function.
