Scientists have revived a worm that was frozen 46,000 years ago — at a time when woolly mammoths, sabre-toothed tigers and giant elks still roamed the Earth. A worm has been revived after 46,000 ...
In 2023, it was reported that nematodes of the previously undescribed Panagrolaimus kolymaensis were revived after 46,000 years in cryptobiosis. [2] [3] However, a number of scientists expressed skepticism regarding the accuracy of the age analysis for these worms. [1] Phylogenetic analysis and genome comparison with C. elegans revealed that ...
Once thawed and hydrated, the worms bounced back to life, eating bacteria and producing offspring, researchers said. 46,000-year-old worms discovered on Arctic expedition. Now they’re being revived

Various claims have been made about reviving bacterial spores to active metabolism after millions of years of dormancy. Spores preserved in amber have been revived after 40 million years, [10] and spores from salt deposits in New Mexico have been revived after 250 million years, making these bacteria by far the longest-living organisms ever ...
Nematodes are very small, slender worms. Most are free-living, often less than 2.5 mm long and some only about 1 mm. Many nematodes are microscopic. Some soil nematodes can reach up to 7 mm in length, and some marine species can reach up to 5 cm. Some are parasitic and can reach lengths of 50 cm or more. [42]

Between 1963 and 1991, archaeologists discovered Judean date seeds in excavation sites. Through radiocarbon dating, they were determined to be between 1,900 and 2,300 years old. In 2008, researchers at the Arava Institute for Environmental Studies began to germinate the seeds. [2] As of 2023, 7 Judean date palms have successfully germinated. In ...
