inquiSTR: New Toolkit Enables Rapid, Accurate Analysis of Tandem Repeats Across Populations
Researchers have developed inquiSTR, a command-line toolkit that can genotype nearly 1.78 million tandem repeat loci in under two minutes using long-read sequencing data. Tandem repeats are highly mutable DNA segments linked to human traits and diseases, and efficient tools for analyzing them at population scale have been lacking. The toolkit's speed and accuracy improvements could accelerate research into how these genomic elements contribute to human variation and disease susceptibility.
inquiSTR is a new computational toolkit designed to rapidly and accurately profile tandem repeats—short DNA sequences repeated multiple times in the genome—from large-scale sequencing datasets. The tool leverages efficient parallel processing and low-memory streaming algorithms to genotype a comprehensive catalog of 1.78 million tandem repeat loci in less than two minutes, representing a significant performance improvement over existing methods. Benchmarking against truth sets demonstrates both high accuracy and substantially faster performance compared to alternative tools. Beyond genotyping, inquiSTR provides downstream analytical capabilities including population structure inference, association testing, and outlier detection, making it a comprehensive platform for tandem repeat research.
What's missing
The preprint does not specify availability details (code repository, installation instructions, or publication timeline for peer review), nor does it discuss potential limitations in detecting repeats in highly repetitive genomic regions or with specific sequencing technologies.

Study finds cerebral blood vessel oscillations are self-generated, not driven by systemic blood pressure
Researchers observed that rhythmic oscillations in brain blood vessel diameter persist during cardiopulmonary bypass surgery when systemic blood pressure oscillations are absent, suggesting the brain generates these oscillations independently. The study involved 14 surgical patients and measured vaso-oscillations at approximately 0.1 Hz frequency. This finding challenges the understanding of how blood flow and fluid transport are regulated in the brain.
New Framework Addresses Missing Data in Space Biology Research Using NASA RR9 Mission Data
Researchers have developed a systematic four-stage imputation framework to handle incomplete datasets from space biology experiments, demonstrated using retinal imaging and omics data from NASA's RR9 mission. Space biology studies are inherently limited by small sample sizes and logistical constraints, making missing data a significant obstacle to building reliable computational models of how the human body responds to spaceflight. The framework is important because it provides practical guidance for preserving biological signals while quantifying trade-offs, though it reveals that imputation can simultaneously improve predictive performance and obscure subtle biological patterns.
OMIO: New Python Library Standardizes Microscopy Image Data Handling
Researchers have developed OMIO, a Python library that standardizes how microscopy images and their metadata are read and processed across different file formats and microscope systems. The tool addresses a longstanding problem in microscopy workflows where different file formats and reader software often introduce errors, metadata loss, or require custom workaround code. This standardization could improve reproducibility and reduce errors in microscopy-based research across biology, medicine, and materials science.
