High resolution long-read telomere sequencing reveals dynamic mechanisms in aging and cancer

Nature Communications
Telomeres are the protective nucleoprotein structures at the end of linear eukaryotic chromosomes. Telomeres’ repetitive nature and length have traditionally challenged the precise assessment of the composition and length of individual human telomeres ...

Compound Heterozygote Friedreich Ataxia Patients With Covert Proximal FXN Gene Deletions

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT We present Friedreich ataxia patients with frataxin gene deletions. Data and records were collected at the Children's Hospital of Philadelphia from patients enrolled in the FACOMS natural history study. Patients with proximal deletions initially diagnosed with only one GAA expanded allele had more severe disease than their homozygous expansion

MethPhaser: methylation-based long-read haplotype phasing of human genomes

Nature Communications
The assignment of variants across haplotypes, phasing, is crucial for predicting the consequences, interaction, and inheritance of mutations and is a key step in improving our understanding of phenotype and disease.

Consistent ultra-long DNA sequencing with automated slow pipetting

BMC Genomics, 2021
Background Oxford Nanopore Technologies’ instruments can sequence reads of great length. Long reads improve sequence assemblies by unambiguously spanning repetitive elements of the genome.

Low‐Cost, Large‐Scale Nanoporous Metals by Mechanical Alloying, Oxide Reduction, and Dealloying of Powders

Advanced Engineering Materials, EarlyView.
Powder metal processing provides scalable advantages in nanoporous (np) metal development. Mechanical alloying is used to produce unique precursors for hybrid nanopore formation by oxide reduction and dealloying. As demonstrated in np Ag, this approach improves process efficiency while promoting smaller ligaments and larger pores, both of which are ...

Borg extrachromosomal elements of methane-oxidizing archaea have conserved and expressed genetic repertoires

Nature Communications
Borgs are huge extrachromosomal elements (ECE) of anaerobic methane-consuming “Candidatus Methanoperedens” archaea. Here, we used nanopore sequencing to validate published complete genomes curated from short reads and to reconstruct new genomes.

Evaluation of strategies for the assembly of diverse bacterial genomes using MinION long-read sequencing

BMC Genomics, 2019
Background Short-read sequencing technologies have made microbial genome sequencing cheap and accessible. However, closing genomes is often costly and assembling short reads from genomes that are repetitive and/or have extreme %GC content remains ...
