Arctic Warming Accelerates: Rivers Turn Rust Red as Thaw Unlocks Iron
Overview: A Region Warms Faster Than the Global Average New findings from climate researchers underscore a troubling reality: the Arctic is warming much faster than the rest of the planet. The rapid temperature rise is not only amplifying ice loss and changing wildlife patterns, but it is also tugging iron from long-frozen soils into rivers…

Rusting Rivers: How Arctic Warming Is Transforming Rivers with Iron Fe from Permafrost
What is happening to Arctic rivers? New research shows a striking and alarming side of climate change: hundreds of rivers and streams across the Arctic are turning bright red-orange. This color change isn’t caused by pollution or a dye spill. Instead, it results from naturally occurring iron being released as the long-frozen ground thaws. Scientists…

Ancient RNA Snapshot: A Woolly Mammoth’s Life 39,000 Years Ago
The remarkable discovery in Siberia In the frozen soils of present-day Siberia, a woolly mammoth named Yuka has become a time capsule from the late Pleistocene. When a mammoth dies and encases itself in permafrost, its tissues can be preserved for tens of thousands of years. Yuka’s remains—hair, muscle, and other soft tissues—have offered scientists…

Ancient RNA Reveals Mammoth Yuka’s Life 39,000 Years Ago
Unraveling Yuka’s Life Through Ancient RNA In the frozen corridors of Siberia, a woolly mammoth named Yuka has become a molecular time capsule. While many fossils offer a snapshot of anatomy, a new approach—ancient RNA analysis—lets scientists glimpse not just what Yuka looked like, but how she lived. Preserved in permafrost, Yuka’s hair, skin, and…
