As presented at the ESMO Congress 2025: Results of the phase 2/3 AGITG DYNAMIC-III trial show that de-escalated chemotherapy based on ctDNA-negative status in patients with stage III colon cancer did not meet non-inferiority for 3-year recurrence-free survival when compared to standard of care, although it enables better informed treatment decisions.

An analysis of 24,202 critical cases of COVID-19 identifies potentially druggable targets in inflammatory signalling (JAK1), monocyte–macrophage activation and endothelial permeability (PDE4A), immunometabolism (SLC2A5 and AK5), and host factors required for viral entry and replication (TMPRSS2 and RAB2A).

A global network of researchers was formed to investigate the role of human genetics in SARS-CoV-2 infection and COVID-19 severity; this paper reports 13 genome-wide significant loci and potentially actionable mechanisms in response to infection.

NAFLD prevalence in most regions of Asia is increasing. This Review presents emerging data on genetic polymorphisms that predispose Asian people to NAFLD, NASH and cirrhosis, and discusses the clinical and pathological outcomes of these diseases.

Analyses of 2,658 whole genomes across 38 types of cancer identify the contribution of non-coding point mutations and structural variants to driving cancer.

In somatic cells the mechanisms maintaining the chromosome ends are normally inactivated; however, cancer cells can re-activate these pathways to support continuous growth. Here, the authors characterize the telomeric landscapes across tumour types and identify genomic alterations associated with different telomere maintenance mechanisms.

Whole-genome sequencing data from more than 2,500 cancers of 38 tumour types reveal 16 signatures that can be used to classify somatic structural variants, highlighting the diversity of genomic rearrangements in cancer.

Genome-wide ancient DNA data from individuals from the Middle Bronze Age to Iron Age documents large-scale movement of people from the European continent between 1300 and 800 bc that was probably responsible for spreading early Celtic languages to Britain.

A pan-cancer genomic analysis reports the effects of structural variations on chromatin domains (TADs). Most TAD disruptions do not result in appreciable changes in expression of nearby genes.

An analysis of 2,954 genomes from 38 cancer subtypes identified 19,166 retrotransposition events in 35% of samples. Aberrant LINE-1 retrotranspositions can lead to the deletion of tumor-suppressor genes as well as the amplification of oncogenes.

In this study the authors consider the structural variants (SVs) present within cancer cases of the ICGC/TCGA Pan-Cancer Analysis of Whole Genomes (PCAWG) Consortium. They report hundreds of genes, including known cancer-associated genes for which the nearby presence of a SV breakpoint is associated with altered expression.

Cancers evolve as they progress under differing selective pressures. Here, as part of the ICGC/TCGA Pan-Cancer Analysis of Whole Genomes (PCAWG) Consortium, the authors present the method TrackSig the estimates evolutionary trajectories of somatic mutational processes from single bulk tumour data.

Zheng et al. developed LLM4SD, a framework using large language models to predict molecular properties. The method leverages the ability of large language models to synthesize knowledge from literature and to reason about scientific data with domain expertise.

Cull plan splits farmers, conservationists — and scientists.

In the wake of Columbia's loss, NASA's efforts to replace its ageing shuttle fleet are coming under fresh scrutiny. Geoff Brumfiel uncovers a tale of high hopes, false starts and immense technical hurdles.

The ages and geochemical compositions of inclusions of sublithospheric diamonds indicate additions to the mantle keel of Gondwana by the underplating of buoyant subducted material, originating from 300–700-km depth, which may have contributed to supercontinent stability during long-distance migration.

The authors identify copy number signatures from shallow whole-genome sequencing of high-grade serous ovarian cancer (HGSOC) cases. HGSOC comprises a continuum of genomes shaped by multiple mutational processes that result in genomic aberration.

Collaborations between Western researchers and former Soviet bioweapons scientists could benefit both parties. But mistrust and bureaucracy are getting in the way, says Geoff Brumfiel.

Parity induces an accumulation of CD8⁺ T cells, including cells with a tissue-resident-memory-like phenotype within human normal breast tissue, offering long-term protection against triple-negative breast cancer.

Multimode ultrastrong coupling between 3D photonic-crystal cavity modes and the cyclotron resonance of a 2D electron gas reveals distinct coupling scenarios governed by the cavity’s spatial profile and potential intermode ground-state correlations.

Whole-genome sequencing, transcriptome-wide association and fine-mapping analyses in over 7,000 individuals with critical COVID-19 are used to identify 16 independent variants that are associated with severe illness in COVID-19.

Mary Relling and colleagues explore the effects of ancestry on the pharmacogenomics of relapse in acute lymphoblastic leukemia. They found that Native American ancestry was associated with risk of relapse but that differences in relapse risk were abrogated by the addition of a single extra phase of chemotherapy.

Some cancer patients first present with metastases where the location of the primary is unidentified; these are difficult to treat. In this study, using machine learning, the authors develop a method to determine the tissue of origin of a cancer based on whole sequencing data.

A case–control study investigating the causes of recent cases of acute hepatitis of unknown aetiology in 32 children identifies an association between adeno-associated virus infection and host genetics in disease susceptibility.

Typhoid fever is caused by Salmonella enterica serovar Typhi (S. Typhi). This study examines ∼2,000 clinical isolates of S. Typhi to show highly structured/geographically restricted genomes except rapidly disseminating H58 subclade, and design a genotyping framework for tracking the disease.

Understanding deregulation of biological pathways in cancer can provide insight into disease etiology and potential therapies. Here, as part of the PanCancer Analysis of Whole Genomes (PCAWG) consortium, the authors present pathway and network analysis of 2583 whole cancer genomes from 27 tumour types.
