Determining cellular phylogeny and migration at high resolution in spatial genomics

StarTrak infers cellular migration and phylogeny by integrating somatic variants, spatial data, and transcriptomics at single-pixel resolution in spatial genomics.

Population-scale Y chromosome assemblies reveal recurrent remodeling within constrained architectures

The paper presents a population-scale Y chromosome reference panel with 142 assemblies, revealing structural and epigenetic variation across 180,000 years of evolution.

A global view of human centromere variation and evolution

The paper assembles and characterizes 2,110 human centromeres, revealing novel haplotypes, mobile element insertions, and mutation rate variation across chromosomes.

Complex genetic variation in nearly complete human genomes

Hybrid HiFi/ultra-long ONT assemblies of 65 diverse humans yield 130 haplotypes, 1,246 complete centromeres, and a pangenome panel enabling short-read genome inference at median QV 45.

Homomorphic Encryption: An Application to Polygenic Risk Scores

This paper applies fully homomorphic encryption to compute polygenic risk scores securely, showing high accuracy and feasibility with synthetic and real data.
