A century-old Stonehenge mystery may finally be solved
Scientists have found compelling new evidence that humans, not glaciers, brought Stonehenge’s bluestones to the site. Using advanced mineral analysis, researchers searched nearby river sediments for signs glaciers once passed through the area—and found none. That missing signature strongly suggests the stones were intentionally moved by people. How they did...
Scientists finally explain Earth’s strangest fossils
The Ediacara Biota are some of the strangest fossils ever found—soft-bodied organisms preserved in remarkable detail where preservation shouldn’t be possible. Scientists now think their survival in sandstone came from unusual ancient seawater chemistry that created clay “cements” around their bodies after burial. This process captured delicate shapes that would...
In Polar Regions, Microbes are Influencing Climate Change as Frozen Ecosystems Thaw, McGill Review Finds
Microbes across Earth’s coldest regions are becoming more active as glaciers, permafrost and sea ice thaw, accelerating carbon release and potentially amplifying climate change, according to a new international review from McGill University.
Sea Levels Are Rising—But in Greenland, They Will Fall
Even as global warming causes sea levels to rise worldwide, sea levels around Greenland will likely drop, according to a new paper in Nature Communications.
New Data Show Reduced Overall PFAS Exposures in Subarctic Ocean
PFAS, or per- or polyfluoroalkyl substances, are ubiquitous in modern life. First produced at the end of World War II, these chemicals are in everything from furniture and cosmetics to food packaging, non-stick pans and clothing.
Higher Costs for Green‑Hydrogen Transport in the Nordics
Green hydrogen produced using solar and wind power would be cheaper to produce at more southerly latitudes than in the Nordic region.
40 Years of Tracking Trees Reveals How Global Change Is Impacting Amazon and Andean Forest Diversity
New research published in Nature Ecology and Evolution reveals significant recent shifts in tree diversity among the tropical forests of the Andes and Amazon, driven by global change.
Hubble Observes Ghostly Cloud Alive with Star Formation
While this eerie NASA Hubble Space Telescope image may look ghostly, it’s actually full of new life.
New DNA analysis rewrites the story of the Beachy Head Woman
A Roman-era skeleton discovered in southern England has finally given up her secrets after more than a decade of debate. Known as the Beachy Head Woman, she was once thought to have roots in sub-Saharan Africa or the Mediterranean—an idea that sparked global attention. But new, high-quality DNA analysis paints...
