Nature Communications, Published online: 15 June 2026; doi:10.1038/s41467-026-73847-x Here the authors generate a new genome and the first embryonic methylomes of an Australian marsupial to show that the embryo retains high DNA methylation while the trophectoderm undergoes erasure, suggesting placental epigenetic reprogramming is ancestral to therians.

Larger leaves, bigger cells, and faster vegetative growth are familiar advantages of triploid poplars, but the molecular logic behind these traits has remained difficult to explain. A new study identifies a feed-forward loop (FFL) involving PpnGATA8, PpnGRF5, and PagXTH9 that helps convert polyploid gene dosage into enlarged leaf cells and improved photosynthetic performance.

Pepper growers often face a practical challenge: the same lateral branches that support fruit production can also increase pruning demands and production costs. A new study uncovers a molecular control point behind this balance, showing how one transcription factor promotes branch growth while an interacting energy-related protein restrains it.

Plant scientists are searching for faster, more flexible ways to rewrite crop genomes without relying on slow and difficult transformation pipelines. A new study shows that plant viruses from the potyvirus group can act as delivery vehicles for genome-editing instructions in plants that express Cas12a.

What if the origins of human language were hidden in a tiny piece of DNA all along? Researchers have identified a genetic link that traces back deep into prehistory.

Nature Immunology, Published online: 15 June 2026; doi:10.1038/s41590-026-02563-x Here, the authors conduct integrated multiomics analysis of B cell activation, differentiation and diversification responses to malaria infection and provide a graphical user interface for readers to mine these data.

Researchers used genome editing to block the production of red pigments in lettuce, causing other beneficial plant compounds to build up instead. The lettuce continued to grow normally, pointing toward a new way to create crops with customized nutritional profiles.

Meet Andrea Ganna, new Senior Group Leader in the Health Data Science Research Centre. His research integrates genetics, electronic health records, national health registries and population-scale biobanks to improve the early detection of common diseases and support more effective public health interventions. The post Introducing Andrea Ganna appeared first on Human Technopole .

Scientific Reports, Published online: 15 June 2026; doi:10.1038/s41598-026-58118-5 Whole-genome sequencing and analysis of the endophytic fungus Alternaria alternata Y-2 from Leymus chinensis

Nature Communications, Published online: 15 June 2026; doi:10.1038/s41467-026-74420-2 Lampreys use variable lymphocyte receptors (VLRs) for adaptive immunity, but the cellular organization of VLR diversity is unknown. This study reveals an invariant VLR-like receptor in lamprey T-like cells that coordinates with diversified VLRC, defining a distinct T-like sub-population in lamprey.

Nature Communications, Published online: 15 June 2026; doi:10.1038/s41467-026-74204-8 Small cell carcinoma of the ovary, hypercalcemic type, is a rare, aggressive cancer caused by SMARCA4 inactivation and features wild-type p53. Here, the authors suggest that loss of SMARCA4 alters chromatin and reprograms p300 binding, undermining p53’s transcriptional repression and promoting cancer growth.

New research to be presented today (Monday) at the annual conference of the European Society of Human Genetics shows that a cancer patient's genetic ancestry can have a significant effect both on how their disease progresses and their survival. In the largest study of its kind, researchers examined nearly 1,900 specific genetic changes in tumors in order to measure whether certain mutations were …

Scientific Data, Published online: 15 June 2026; doi:10.1038/s41597-026-07359-0 The first telomere-to-telomere genome assembly of a freshwater bivalve: Gibbosula rochechouartii

A new test provides a much more complete picture of DNA than current standard diagnostics and leads to a diagnosis more often. The test can replace 15 other tests, making it faster and more efficient. Researchers from Radboud university medical center recommend in the New England Journal of Medicine that this test be adopted everywhere […]

Do genes dictate academic success? A new study of European twins shows the answer depends on where you live. Different school systems and family backgrounds can actually change how much a student's natural ability matters in the classroom.

For the first time, researchers connected a person's overall genetic risk for ADHD to specific irregularities in how their brain coordinates attention. The finding bridges the gap between inherited DNA and observable neurological changes.
