Dynamic principles of concentration buffering through liquid-liquid phase separation.

Living systems must maintain robust biochemical function despite fluctuations that span a wide range of timescales. Biomolecular condensates formed by liquid-liquid phase separation (LLPS) have been shown to buffer concentration fluctuations, but the principles governing their dynamic regulation remain unclear. We address this by probing the response of LLPS to oscillatory perturbations that mimic fluctuations across different timescales, establishing the first systematic frequency-domain analys

Folic acid prevention of neural tube defects requires retinoic acid produced by ALDH1L1.

Folic acid (FA) supplementation during pregnancy is the commonly accepted treatment to prevent neural tube defects. The mechanism by which FA prevents neural tube defects (NTDs) remains unclear. FA also prevents other developmental malformations, including alcohol-induced malformations in Fetal Alcohol Syndrome models. We show that FA acts through a metabolic link to retinoic acid (RA) signaling. Using a pax3 -knockdown Xenopus model of FA-rescuable NTDs, we show that RA or its precursors equall

X-linked SYTL4 missense variant disrupts RAB27A-dependent vesicle trafficking and synaptic transmission in autism.

Autism spectrum disorder (ASD) is a neurodevelopmental condition characterized by impaired social communication and repetitive behaviors, with genetic studies implicating widespread synaptic dysfunction. However, the contribution of presynaptic vesicle trafficking mechanisms to ASD pathogenesis remains incompletely understood. Here, we identify synaptotagmin-like protein 4 (SYTL4), a RAB27A effector previously characterized in secretory cells, as a regulator of presynaptic function in the mammal

Basement membrane turnover controls cell shape.

The regulation of 3D cell shape is a fundamental problem of life. In multicellular tissues, cell shape emerges through the balance of forces inside and outside the cell. In epithelia, the basement membrane (BM) is the first extracellular barrier that cells sense biochemically and mechanically. Despite this, little is known about how BM mechanical properties are regulated and how they impact cell shape. Through mathematical modeling, we show that the stress relaxation time of the BM can regulate

Dietary arginine drives codon-dependent MHC class I translation and improves immunity in colon tumorigenesis and respiratory viral infection.

Amino acid levels fluctuate across diverse pathological conditions. Whether such amino acid modulations directly shape pathophysiology by regulating host gene expression remains unknown. We found that extracellular arginine restriction, observed in cancer and infection, represses specific arginine tRNAs-directly suppressing translation of major histocompatibility complex I (MHC class I) and antigen presentation. Arginine regulation of MHC class I was codon-usage dependent, as synonymous codon mu

Initial HIV Therapy for Adults and Treatment-Associated Weight Gain: The Opti-DOR Randomized Clinical Trial.

Antiretroviral therapy (ART), particularly regimens containing tenofovir alafenamide with dolutegravir or bictegravir, is associated with substantial weight gain, potentially exacerbating cardiometabolic risk in people with HIV. To determine whether a regimen with doravirine, lamivudine, and tenofovir disoproxil fumarate results in less weight gain than a regimen with dolutegravir, emtricitabine, and tenofovir alafenamide while maintaining noninferior viral suppression. Open-label, noninferiorit

Nature's antivenom: Combinations of conserved rattlesnake serum metalloproteinase inhibitors block the lethal action of viper venoms.

Snakebite maims or kills several hundred thousand people each year. For more than a century, treatment has relied on antivenoms derived from animals immunized with whole venoms, but their efficacy, safety, and availability are highly variable, and it is often not well understood which specific venom components must be inhibited to prevent mortality and major morbidities. New therapeutic approaches are needed. Here, we take an evolutionary approach to antivenom design inspired by the longstanding

Reversing vegetable biodiversity loss to diversify diets.

Vegetables are a critical component of diets, with inadequate intake of this essential food group leading to poor dietary quality and malnutrition. Food system assessments identify insufficient production, comparatively high prices, and sociocultural barriers as key constraints to vegetable consumption. We argue that vegetable biodiversity, spanning vegetable species and their varieties, as well as their wild relative species, is a central yet underutilized lever for enhancing vegetable consumpt

PLK1-mediated phosphorylation of PHGDH reprograms serine metabolism in advanced prostate cancer.

Metabolic reprogramming is a hallmark of cancer, enabling tumor cells to meet their increased biosynthetic and energetic demands. Although cells possess the capacity for de novo serine biosynthesis, most transformed cancer cells preferentially rely on exogenous serine uptake to sustain their growth, yet the regulatory mechanisms driving this metabolic dependency remain poorly understood. Here, we uncover a mechanism by which Polo-like kinase 1 (PLK1), frequently overexpressed in prostate cancer,

When coordination is avoidable: A monotonicity analysis of organizational tasks.

Organizations devote substantial resources to coordination, yet which tasks actually require it for correctness remains unclear. The problem is acute in multiagent AI systems, where coordination cost is directly measurable and can exceed the cost of the work itself. Distributed systems theory provides a precise criterion: Coordination is required when a task specification is nonmonotonic, meaning that as histories grow, new information can invalidate prior conclusions.

Synergistic action of different molecular mechanisms causes striking levels of insecticide resistance in the malaria vector Anopheles gambiae .

Intensifying insecticide resistance in the malaria vector Anopheles gambiae poses a serious threat to the progress achieved the last decades in reducing malaria deaths in Africa.

However, we still lack a clear understanding of how each mechanism contributes to overall resistance and how highly resistant phenotypes arise. In this study, we generated a suite of transgenic An. gambiae strains carry

There is no free benchmark: An institutional view of legal AI benchmarking.

Sediment accumulation rate predicts the temporal resolution of marine fossil assemblages.

Time averaging (TA), the mixing of noncontemporaneous organisms in fossil assemblages, governs the resolution of paleontological data and determines which biological and environmental processes are recorded in the geological record.

Bivalve mollusks dominated the data,

Geometry controls momentum flux in the sprinkler problem.

Hydro- and aero-mechanical devices convert fluid flows into useful motions, force, and power. The operating principles can involve subtle and poorly understood physics, as epitomized by open questions about systems that aspirate flows through curving tubular arms.

Guanidine fuels rapid resurrection of desert cyanobacteria.

In desert ecosystems, microbial activity is driven by brief hydration pulses but is severely limited by persistent nutrient scarcity. Cyanobacteria serve as essential pioneer photoautotrophs, maintaining biogeochemical cycles and ecosystem stability in these arid landscapes. However, their ability to quickly reactivate after rehydration is critically restricted by nitrogen availability. Although the nitrogen demand can be met later by biological nitrogen fixation, it is ineffective and irrelevan

The social-class gap in negotiation: Lower-class individuals negotiate less and face more backlash.

Economic inequality has widened considerably in the United States and globally, raising pressing questions about the mechanisms that reproduce social stratification. One prominent manifestation of this inequality is the "class ceiling" in organizations: individuals from lower social classes earn less and advance more slowly than their higher-class counterparts, even with comparable credentials. We identify a crucial behavioral pathway contributing to this class ceiling: a social-class gap in the

Dynamic Coordination-Enabled Metal-Dependent Configurational Switching in a Covalent Organic Framework.

Anionic Passivation Enables Reconstruction-Free Seawater Electrolysis.

Nonoxide electrocatalysts hold great promise for high-efficiency seawater oxidation, yet their practical application is hindered by the inevitable surface reconstruction and pronounced corrosion under high anodic potentials.
