Researchers discovered that chronic inflammation fundamentally remodels the bone marrow, allowing mutated stem cell clones to quietly gain dominance with age. Reprogrammed stromal cells and interferon-responsive T cells create a self-sustaining inflammatory loop that weakens blood production. Surprisingly, the mutant cells themselves may not be the main instigators.

Scientists confirmed that West Coast transient killer whales actually form two separate groups split between inner and outer coastal habitats. Inner-coast whales hunt smaller prey in shallow, maze-like waterways, while outer-coast orcas pursue large marine mammals in deep offshore canyons. The groups rarely interact, despite sharing a broad range along the Pacific Coast. Their contrasting lifestyles highlight the need for distinct conservation strategies. Source link
New climate modeling shows that heatwaves will keep getting hotter, longer, and more frequent for centuries—even after the world hits net-zero emissions. Delays of just a few years dramatically increase the likelihood of extreme, once-rare heat disasters, especially for countries near the equator. The research reveals that even reaching net zero by mid-century won’t reverse the trend, and some regions will continue to see worsening heatwaves for a thousand years. Source link
Scientists may finally be closing in on the origins of two colossal, mysterious structures buried nearly 1,800 miles inside Earth—hidden formations that have puzzled researchers for decades. New modeling suggests that slow leakage of elements from Earth’s core into the mantle prevented the planet from developing strong chemical layers after its primordial magma-ocean era. Source link
