This energy thread follows nuclear through original research, public projects, and source reports. Read the evidence below to see which developments are represented in SYMTRI’s archive.
SYMTRI organizes observations from public sources into a living map. Connections reflect shared subject matter; they do not establish causation or endorse a source.
Open in the map ↗59 classified signals in the fourteen-day window. These counts include signals awaiting readable evidence.
Earlier sources
Up to ten sources with readable evidence, ordered by their feed timestamp. These archive sources can be older than the live fourteen-day window. This list is a sample, not a measure of total activity. Dates distinguish paper publication, repository creation, model/dataset activity, Hacker News posts, and KEV catalog additions. “First archived” records when SYMTRI first stored the signal.

ZC3H14 phosphorylation is required for nuclear speckle assembly during zygotic splicing activation in mice ↗
Following zygotic genome activation (ZGA) in embryos, nuclear speckles, which are subnuclear domains where pre-mRNA undergoes splicing, are reassembled in a process called zygotic splicing activation (ZSA). ZSA is vital for early development, but its regulation is poorly understood. This study identifies the RNA-binding protein ZC3H14 as a key promoter of nuclear speckle formation during ZSA. Although viable, Zc3h14 knockout mice exhibit reduced female fertility. Most embryos from these females arrest during the 1-cell to 2-cell transition, and the remaining embryos arrest at the 2-cell stage,…

A nuclear clock synchronized to 229Th ↗
Abstract Atomic clocks have made time and frequency the most precisely measured quantities in physics, progressing from microwave standards that realize the SI second 1 to optical clocks with unprecedented precision 2 . A nuclear clock transfers the frequency reference from an electronic to a nuclear transition and the uniquely low-lying, laser-accessible, isomeric transition in 229 Th currently offers the most practical route to compact, robust timekeeping and sensitive tests of fundamental physics 3–8 . Realizing such a clock requires turning spectroscopy of the 229 Th nuclear resonance 9–17…

Recognized but displaced: Uranium mill tailings and the sustainability accounting of nuclear energy ↗
Nuclear-energy sustainability is usually debated through reactor performance, carbon intensity, fuel availability, operational safety and spent-fuel disposal. Less visible are the front-end residues generated by uranium production, especially uranium mill tailings (UMT), likely the nuclear fuel cycle's largest long-lived radioactive residue stream by volume. This Perspective argues that UMT are not merely neglected; they are recognized and displaced through nested governance boundaries. It develops the concept of volume-based leniency and identifies three linked mechanisms: classification disp…

Nuclear–Electronic Orbital Coupled Cluster Theory with the Nuclear Hartree Product Representation for Multiple Quantum Nuclei and Application to Geometric Isotope Effects ↗
Abstract Nuclear–electronic orbital (NEO) methods treat specified nuclei, typically protons, quantum mechanically on the same level as electrons within quantum chemical calculations. This approach allows the computationally efficient inclusion of nuclear quantum effects such as nuclear delocalization, anharmonic zero-point energy, and tunneling into energy calculations, geometry optimizations, and dynamics. NEO coupled cluster (NEO-CC) methods recover correlation to an extent that enables prediction of accurate ground-state properties for moderately sized systems. Herein, NEO-CCSD(T), which in…

Genetic Background of the Hetian Rose Inferred from SNPs in Single-Copy Nuclear Loci and Plastid Genomes ↗
Background/Objectives: The Hetian Rose (Rosa ‘Hetian’) is a locally important oil-bearing rose cultivar grown in Hetian, Xinjiang, China, but its genetic origin remains unclear. Methods: To clarify its genetic background, we sampled R. ‘Hetian’ together with 35 related Rosa species and cultivars and performed phylogenetic and genetic-structure analyses using 7478 SNPs in 1851 single-copy nuclear loci. We also reconstructed a plastid genome phylogeny to assess its maternal-lineage affinity. Results: In the nuclear SNP phylogeny, R. ‘Hetian’ was associated with European rose lineages rather than…

Inverse relationship between mitochondrial and non-coding nuclear DNA content in free-living kinetoplastids ↗
The evolution of genome size and eukaryotic genome organisation has puzzled evolutionary biologists for decades. Are differences in DNA content and protein-coding capacity of eukaryotic genomes a result of natural selection, or neutral processes? If they were shaped by natural selection, which features might be connected with these differences: cell volume, ecological strategy, availability of nutrients, etc.? Kinetoplastids are protists with compact nuclear genomes that almost entirely lack introns, but whose mitochondrial DNA content (kDNA) can rival that of their nuclei. We hypothesised tha

Chromatin-associated intronic RNAs from long genes form introsomes that shape nuclear architecture in neuronal cells ↗
Abstract Cell differentiation towards neurons is accompanied by widespread changes in three-dimensional (3D) genome organization and gene expression. Chromatin-associated RNAs have been proposed to be important regulators of such changes; however, the type, abundance, and role of these RNAs during neuronal differentiation remain largely unexplored. Here, we integrate multi-omic data generated in the frame of the Functional ANnoTation Of the Mammalian genome (FANTOM6) to chart 3D genome, RNA-DNA contactome, and transcriptome changes occurring during in vitro differentiation of human induced plu

Burnup-dependent nuclear safeguards and security assessment of HALEU-Fueled sodium-cooled fast reactors ↗
This study presents a burnup- and cooling-time-dependent assessment of safeguards- and security-relevant characteristics of spent fuel from high-assay low-enriched uranium (HALEU)-fueled sodium-cooled fast reactors (SFRs). A physics-based framework is adopted to evaluate spent fuel in terms of three functions: material attractiveness, self-protection, and monitorability. Within this framework, decay heat, photon emission rate, spontaneous fission rate, and external dose rate are treated as key spent-fuel attributes that collectively determine safeguards and security functions. Burnup-dependent…

Estrogen Receptor Beta Isoforms Interplay Integrates Nuclear and Extra‐Nuclear Signaling to Modulate Human Granulosa Cell Growth ↗
Estradiol (E2) regulates ovarian follicular development and granulosa cell (GC) function primarily through estrogen receptor β (ERβ). Human GCs express several ERβ isoforms, including ERβ1, ERβ2, ERβ4, and ERβ5, but how their relative abundance modulates estrogen signaling remains unclear. Here, we investigated the contribution of nuclear and extra-nuclear ERβ signaling to human GC growth and function. HGrC1 granulosa cells lacking endogenous estrogen receptors were engineered to stably express individual or combined ERβ isoforms. Functional analyses showed that ERβ1 and ERβ4 inhibited GC prol…

How to assess evidence about Nuclear
Check each original source for its methods, release status, limitations, and supporting data. A repository announcement, a preprint, and a published study provide different kinds of evidence. SYMTRI’s subject classification helps discovery; it does not independently validate the source’s claims.
