Here, the authors show that SAA amplified αSyn aggregates from the CSF of a multiple system atrophy patient retain the biological and structural properties of the aggregates deposited in the brain

Results for the final phase of the 1000 Genomes Project are presented including whole-genome sequencing, targeted exome sequencing, and genotyping on high-density SNP arrays for 2,504 individuals across 26 populations, providing a global reference data set to support biomedical genetics.

Poly-ADP-ribose polymerase 1 (PARP1) plays key roles in DNA repair, transcription, and replication. Here, the authors used a single-molecule approach to reveal how PARP1 identifies DNA single-strand breaks in nucleosomes and how PARP1 activity regulates its DNA and chromatin binding kinetics.

A wealth of gene expression data is publicly available, yet is little use without additional human curation. Ma’ayan and colleagues report a crowdsourcing project involving over 70 participants to annotate and analyse thousands of human disease-related gene expression datasets.

A sequencing chemistry that separates nucleotide identification from nucleotide incorporation achieves high accuracy.

Clinical management of pancreatic cancer remains challenging. Here, the authors suggest SMARCD3 as a potential epigenetic dependency establishing the metabolic landscape in aggressive pancreatic cancer cells and as a potential therapeutic target in pancreatic cancer.

Here, the authors provide molecular insight into the remarkable ability of Tardigrades to withstand high levels of radiation by demonstrating that their Dsup protein interacts with multiple surfaces of the nucleosome to protect the genome from oxidative DNA damage.

Distal gene regulation is increasingly recognised as a major contributor to complex trait variability. Here, the authors show that a heritable, biologically interpretable transcriptome signature driven by distal regulation predicts metabolic traits across mice and humans.

Sydnor et al. developed a new tractography atlas of thalamocortical structural connections and applied it to three youth samples. They uncovered coordinated development between thalamic connectivity and hierarchical cortical plasticity in humans.

An optimal model-experiment integration for testing many complex hypotheses is still lacking. Here authors introduce improv, a modular software platform enabling real-time adaptive neuroscience experiments, orchestrating parallel data collection, modeling, and experimental control. Authors demonstrate various use cases, including online neural analysis and closed-loop optogenetics in zebrafish.

The goal of the 1000 Genomes Project is to provide in-depth information on variation in human genome sequences. In the pilot phase reported here, different strategies for genome-wide sequencing, using high-throughput sequencing platforms, were developed and compared. The resulting data set includes more than 95% of the currently accessible variants found in any individual, and can be used to inform association and functional studies.

LIG3α forms a complex with XRCC1 during single strand break and base excision repair. Here, the authors show that LIG3α displays higher affinity for nicks than XRCC1 and binds with its N-terminal ZnF domain more avidly to an undamaged nucleosome.
