EventScientists recovered DNA from ground‑squirrel droppings in Yukon’s Klondike Yedoma sediments that includes plants, parasites, megafauna and 30‑kyr‑old antibiotic‑resistance genes such as vancomycin. The warming permafrost threatens to erase this genetic archive before it can be fully studied, urging emissions cuts and cold storage.
Permafrost thaw in Yukon’s Klondike goldfields is erasing a unique molecular archive, including DNA from extinct megafauna and 30‑kyr old antibiotic‑resistance genes, underscoring the need to reduce emissions and preserve remaining records.
Scientists recovered ancient DNA from ground‑squirrel droppings in Yukon’s Klondike permafrost, revealing a 14‑k to 700‑k year record of plants, parasites, and megafauna. The find underscores how thawing permafrost is erasing a unique archive that could illuminate past ecosystems and antibiotic resistance.
Scientists recovered 30‑year‑old permafrost DNA in Yukon that reveals plant, parasite, mammoth, horse and bison remains from 14,000‑to‑700,000‑year span. The warming Arctic threatens to erase this genetic archive before we can fully study it.
