1. 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 a different picture: she was most likely a local woman from Roman Britain.

2. A lost disease emerges from 5,500-year-old human remains

   A 5,500-year-old skeleton from Colombia has revealed the oldest known genome of the bacterium linked to syphilis and related diseases. The ancient strain doesn’t fit neatly into modern categories, hinting at a forgotten form that split off early in the pathogen’s evolution. This pushes the history of treponemal diseases in the Americas back by millennia and shows they were already diversifying long before written records.

3. Ancient people carried a wild potato across the American Southwest

   Long before farming took hold, ancient Indigenous peoples of the American Southwest were already shaping the future of a wild potato. New evidence shows that this small, hardy plant was deliberately carried across the Four Corners region more than 10,000 years ago, helping it spread far beyond its natural range.

4. Forty years of forest data reveal a changing Amazon

   After analyzing 40 years of tree records across the Andes and Amazon, researchers found that climate change is reshaping tropical forests in uneven ways. Some regions are steadily losing tree species, especially where conditions are hotter and drier, while others are seeing gains. Rainfall patterns turned out to be just as important as rising temperatures.

5. This small soil upgrade cut locust damage and doubled yields

   Locust swarms can wipe out crops across entire regions, threatening food supplies and livelihoods. Now, scientists working with farmers in Senegal have shown that improving soil health can dramatically reduce locust damage. By enriching soil with nitrogen, crops become less appealing to the insects, leading to fewer locusts, less plant damage, and harvests that doubled in size.
