A pseudoenzyme sensor of trehalose-6-phosphate directly represses the metabolic integrator SnRK1 in plants.

Trehalose-6-phosphate (T6P) is a central metabolic signal linking sugar availability to plant growth, carbon utilization, and productivity, yet its sensing and signaling mechanisms remain elusive. Using chemical biology and functional approaches, we identify the noncatalytic pseudoenzyme Class-II T6P synthase (TPS-II) as a T6P sensor in Arabidopsis. In the apo state, TPS-II dimerizes to form an autoinhibitory inter-subunit interaction. T6P binding to the N-terminal TPS-like domain triggers a con

Personalized neoantigen-targeting cancer vaccines in ovarian cancer: a phase 1 trial.

Personalized neoantigen-targeting cancer vaccines in the adjuvant setting are of increasing interest across malignancies. Here we report the results of a phase 1 clinical trial testing the feasibility and safety of personalized neoantigen-targeting cancer vaccines for high-grade epithelial ovarian cancer. 'NeoVax' consisted of pools of synthetic long peptides targeting patient-specific neoantigens admixed with the immunostimulant poly-ICLC, was combined with delayed administration of anti-PD-1 a

Talazoparib plus enzalutamide in high-volume metastatic hormone-naive prostate cancer: a randomized phase 2 trial.

Combining inhibition of poly(ADP-ribose) polymerase and androgen receptor (AR) pathway has demonstrated clinical activity in men with metastatic prostate cancer, although the extent of benefit in tumors lacking homologous recombination repair (HRR) gene alterations remains uncertain. We conducted a randomized phase 2 trial evaluating talazoparib plus enzalutamide versus enzalutamide alone in men with high-volume metastatic hormone-naive prostate cancer (mHNPC). Fifty-four patients starting andro

Engineered TYK2 dependence enables myeloid-selective IL-10 receptor agonism.

Interleukin-10 (IL-10) is a central anti-inflammatory cytokine that suppresses immune responses in myeloid cells but can also activate T cells, limiting its therapeutic use in chronic inflammatory diseases owing to narrow efficacy windows and dose-limiting toxicities 1-5 . Here we show that myeloid and T cells differ in their dependence on JAK-family kinase pairing for IL-10 signalling and function. We took advantage of this differential kinase dependence to engineer a tetravalent nanobody-based

Early tetrapod neck mobility modelled using an extant analogue.

Tetrapods arose from lobe-finned fishes with a notochord-dominated axial column 1-3 . During this transition, the skull became separated from the shoulder girdle 4-6 , giving rise to a neck region. This head-shoulder separation has generated hypotheses suggesting that neck mobility increased during the origin of tetrapods, facilitating the ecological transition towards more terrestrial habitats 4,5,7-9 . However, incompletely co-ossified vertebral components 10 have posed a challenge to mod

Sexual dimorphism in epidermal stem cell dynamics.

The epidermis is a stratified epithelium comprising proliferative basal cells and differentiated suprabasal cells that are continuously renewed throughout life. Conflicting theories have been proposed regarding the heterogeneity of the basal cell layer, with some studies proposing that all proliferative cells have self-renewal potential during homeostasis 1-5 . Meanwhile, others posit a model in which stem cell differentiation occurs through an intermediate transit-amplifying-like progenitor sta

A microexon regulatory code reveals autism-linked genetic variation.

Neuronal microexons are a highly conserved class of alternative splicing events enriched in genes with critical functions in nervous system biology 1,2 . Microexon splicing is often disrupted in the brains of autistic individuals, and mice with microexon deficiencies display autism-like phenotypes 1,3,4 . However, the full landscape of microexons is not known, and the impact of genetic variation on these exons has not been systematically investigated. Here, through extensive transcriptome profil

Educational intervention can rewire village social networks.

Social networks shape behaviour, affect information dissemination and undergird collective action. And they can be exploited in the design of interventions in these domains 1-7 . Although social networks obey fundamental principles, such as the degree distribution 8,9 , they can nevertheless evolve as ties form and break. Here, through a randomized controlled trial involving a total of 8,331 people in 110 remote Honduran villages, we evaluate the secondary effects of a 22-month public-health int

Nutrient legacies from elephant megacarcasses create coldspots of biodiversity and hotspots of ecosystem processes.

Terrestrial megafauna (animals >1,000 kg) have substantial impacts on ecosystems while alive; yet, we know little about the impacts of these ecosystem engineers after they die. Like whale carcasses in the ocean, terrestrial megacarcasses may leave ecological legacies via the nutrient pulses they create on the landscape. Here, we investigated the impact of elephant megacarcasses on savanna ecosystems in Kruger National Park, South Africa. To determine how elephant carcasses affect below- and a

Extensive glacier loss in the coterminous United States.

Glaciers populate the mountain ranges of the western conterminous United States and despite their importance to alpine hydrology, their area and volume change have never been comprehensively evaluated. Our study shows that since the mid-twentieth century about one-quarter of the glaciers have disappeared and the overall area and volume are reduced by one-third. The pattern of glacier shrinkage suggests most glaciers in the conterminous United States are largely maintained by local topographic in

The honey bee stinger: An unusual pump with collapsible double pistons.

Most stinging animals deliver venom by contracting muscles around a venom reservoir, but honey bees employ a fundamentally different strategy. The stingers of worker bees have the unique ability to autotomize, separating from the body, to continue to sting independently. Despite more than a century of anatomical descriptions, the mechanics of venom pumping have remained unresolved due to the challenges of observing them in action. We recorded high-speed videos of active, autotomized stingers, co

Ancient DNA challenges to admixture narratives: Insights from Notre-Dame Cemetery (1683-1796) in Colonial Montreal, Canada.

Historical narratives of early colonization in Quebec frequently portray French-Indigenous relations as cooperative and characterized by admixture; which are often mobilized in modern debates on false-indigeneity. These narratives have been studied through genealogical, genetic, and bioarchaeological analyses, yet individuals of African descent remain mostly absent from them, while Indigenous peoples are framed largely in relation to colonists.

Chronic cigarette smoke exposure induces distinct stem cell states driving genetic driver-specific non-small cell lung cancer subtypes.

Cigarette smoke-induced chronic inflammation (CI) potentiates development of non-small cell lung cancer (NSCLC) by mediating genetic and epigenetic events. Using normal lung organoids (LOs), we define how chronic cigarette smoke condensate (CSC) exposure drives two separate stem cell populations to evolve premalignant states harboring progressive epigenetic and linked transcriptomic abnormalities in the absence of major driver mutations.

Maternal ranging strategies facilitate offspring social play at energetic cost in the most solitary ape.

In most vertebrates, social play among peers is considered essential for behavioral development. Yet in solitary species bearing single offspring, opportunities for social play are inherently scarce. Whether mothers of such species actively facilitate play opportunities for their offspring, and at what cost, remains unknown. We used 15 y of behavioral and movement data (∼32,600 observation hours) from 31 wild Bornean orangutan ( Pongo pygmaeus wurmbii ) mother-offspring pairs to test whet

Cell identity competes with surface tension to determine stromal organization in tumor spheroids beyond the CAF shell paradigm.

Cancer-associated fibroblasts (CAFs) are often found forming a peripheral stromal barrier around tumors. Here, this paradigm is challenged using microfabricated 3D cancer-CAF spheroid models combined with quantitative magnetic force tensiometry. A surface tension atlas is established for eight cancer cell lines, three CAF populations, and heterotypic tumor-CAF assemblies, spanning nearly two orders of magnitude. Surface tension is first shown to govern spheroid morphology and modulate drug respo

Deep learning of fossil pollen morphology reveals 25,000 y of ecological change in eastern African grasslands.

Grass (Poaceae) pollen is largely overlooked in investigations of grassland evolution because the pollen of most species cannot be differentiated using traditional optical microscopy. However, the combination of superresolution microscopy and deep learning enables the capture and quantification of distinct morphological variation across the pollen of grass species.

Tyrosine phosphorylation unfolds nucleophosmin and disrupts its integration into the nucleolus.

Nucleophosmin (NPM1) is a multifunctional nucleolar protein essential for ribosome biogenesis, genome stability, and stress responses. Its integration into the nucleolus depends on its oligomerization and multivalent interactions that enable liquid-liquid phase separation (LLPS). Here, we investigate how tyrosine phosphorylation at Tyr17, Tyr29, and Tyr67 located within the interface between monomers at the N-terminal oligomerization domain regulates NPM1 structure and function.

Antiferromagnetism and tightly bound Cooper pairs induced by kinetic frustration.

Antiferromagnetism and superconductivity are often viewed as competing orders in correlated electron systems.

Evolution shapes ecosystem resilience through spatial self-organization.

Drylands are globally widespread and ecologically important but vulnerable to climate change. Many exhibit spatially self-organized vegetation patterns that enhance resilience by enabling vegetation to reorganize their patterns under drying, thereby optimizing water use and maintaining productivity. Plants can also undergo evolution in response to environmental change. Although both spatial self-organization and rapid evolution are fundamental mechanisms of resilience, their interaction remains

Continuous UV irradiation played an inconclusive role in selecting the canonical genetic alphabet.

An abundance of heterocyclic molecules analogous to canonical nucleobases (i.e., adenine, thymine, guanine, cytosine, and uracil) used as the genetic alphabet in DNA and RNA could have been present in various prebiotic environments on early Earth. However, extant biology generally uses the canonical nucleobases and nucleosides as the genetic alphabet, and not any number of possible noncanonical counterparts. Ultraviolet (UV) irradiation was likely abundant on the surface of the early Earth and h

Understanding consciousness (biological and artificial) as a society of self-schemas.

This article argues that human cognition is more than the performance of functions such as memory, decision-making, and attention. The brain also builds schematic models of those cognitive functions and uses those models to monitor, predict, and partially control them. When you introspect, your understanding of who you are and what is happening inside of you is derived from those schematic, sometimes inaccurate, but generally useful models, rather than from the actual cognitive functions that ar

Hyperfunction of PSD-95 leads to hyperexcitability and cognitive abnormalities in MEF2C haploinsufficiency.

Myocyte enhancer factor 2C (MEF2C) is a transcription factor critical for brain circuit development and cognitive behavior. The loss of one copy of MEF2C leads to MEF2C haploinsufficiency syndrome (MCHS), a neurodevelopmental disorder characterized by intellectual disability, epilepsy, and behavioral phenotypes associated with autism spectrum disorders. Given that numerous genes are regulated by MEF2C, the neuronal and behavioral deficits in MCHS are complex, and there is currently no effective
