Researchers analysed 163 ant genomes spanning most living subfamilies and reconstructed the insects' evolutionary history over the past 100 million years. The study found periods of rapid species diversification coinciding with increased activity of transposable elements, the mobile DNA sequences that can shuffle through genomes. The findings suggest genome dynamics played a role in driving the extraordinary diversification of ants, one of the most successful groups in the natural world.

Researchers have published a high-resolution genome-wide association study of roughly 600,000 people with East Asian ancestry, aiming to decompose population-level differences in type 2 diabetes risk. The work, appearing in Nature, identifies ancestry-specific genetic factors that may explain why diabetes patterns differ between East Asian and European populations, with potential implications for risk prediction and treatment across populations.

The Human RNome Project Consortium, an international research collaboration, is working to publish the first-ever complete sequence of RNA across the human body. Building on the legacy of the Human Genome Project, the effort would map the full range of RNA molecules, which play key roles in how genes are expressed. The announcement is drawing attention from the scientific community as a potential milestone in genomics and biomedical research.
