Invasive Species Eradicated in Record Time: How Japan's Kume Island Defeated the Sweet Potato Weevil Twice

The sweet potato weevil, first eradicated from Japan's Kume Island in 2012 using the world's first successful sterile insect technique on beetles, reinvaded in 2021. A Gifu University-led team verified that rapid response with 3 million sterile insects achieved re-eradication in record time, proving the power of Early Detection and Rapid Response (EDRR) for global pest management.

Great Pyramid of Giza: 25,000 Years Old? New Erosion-Based Dating Method Challenges Archaeological Consensus

Italian engineer Alberto Donini's "Relative Erosion Method" suggests the Great Pyramid of Giza may have been built around 25,000 years ago — far older than the accepted 4,600-year timeline. Was Pharaoh Khufu merely a renovator? We explore the controversial findings, mainstream archaeological pushback, and what this means for ancient history.

Cave Lions in Ancient Japan: DNA Analysis Overturns Long-Held Tiger Fossil Theory

A joint research team from SOKENDAI and Peking University has revealed that cave lions (Panthera spelaea) roamed widely across the Japanese archipelago tens of thousands of years ago. DNA analysis of fossils previously thought to be tigers confirmed their true identity, unveiling a lost ecosystem where lions coexisted with Naumann's elephants and giant deer.
