Generating and navigating single cell dynamics via a geodesic bridge between nonlinear transcriptional and linear latent manifolds

The paper introduces GeoBridge, a framework that models cellular dynamics as geodesic trajectories to transform sparse, nonlinear single-cell RNA sequencing data into a continuous, linear latent manifold, thereby enabling the reconstruction of unobserved intermediate states, the inference of pseudo-temporal trajectories, and the controlled navigation between distinct cellular phenotypes.

Benchmarking Heritability Estimation Strategies Across 86 Configurations and Their Downstream Effect on Polygenic Risk Score Performance

This study systematically benchmarks 86 SNP heritability estimation configurations across six tool families and ten method groups, revealing that while heritability estimates vary substantially based on algorithmic choices and standardization, this upstream variability has minimal impact on downstream polygenic risk score performance, suggesting heritability should be treated as a configuration-sensitive parameter rather than a stable scalar.

SEGUID v2: Extending SEGUID checksums for circular, linear, single- and double-stranded biological sequences

This paper introduces SEGUID v2, an enhanced checksum system that extends the original SEGUID to generate orientation- and rotation-invariant identifiers for circular, linear, single-stranded, and double-stranded biological sequences while adopting Base64url encoding for improved compatibility with filenames and URLs.

High-throughput prediction of protein-protein interactions uncovers hidden molecular networks in biosynthetic gene clusters

This study presents a high-throughput pipeline that leverages AlphaFold3 and MMSeqs2 to systematically predict protein-protein interactions across nearly 500,000 pairs in biosynthetic gene clusters, successfully uncovering hidden molecular networks and functional enzyme complexes involving previously uncharacterized proteins.

Adaptive Cluster-Count Autoencoders with Dirichlet Process Priors for Geometry-Aware Single-Cell Representation Learning

This study introduces Adaptive Cluster-Count Autoencoders with Dirichlet Process Priors, which significantly enhance the geometric compactness and separation of single-cell latent spaces at a modest cost to label-recovery accuracy, thereby establishing a task-dependent trade-off where nonparametric priors are optimal for trajectory analysis and manifold visualization rather than strict cluster counting.

Simplex-Constrained Neural Topic VAEs with Flow Refinement for Interpretable Single-Cell Gene-Program Discovery

The paper introduces Topic-FM, a novel family of neural topic VAEs that enforces simplex constraints via a logistic-normal Dirichlet prior and employs a conditional optimal-transport flow to simultaneously enhance clustering performance, supervised discrimination, and biological interpretability of gene programs across diverse single-cell RNA sequencing datasets.
