Ancient RNA recovery reveals gene activity in Ice Age mammoths
Berlin, Germany (SPX) Nov 15, 2025 Researchers from Stockholm University have isolated and sequenced RNA molecules from the tissue of woolly mammoths that lived nearly 40,000 years ago. The study, published in Cell, provides evidence that RNA can be preserved in permafrost over extensive periods and drives new research into the biological history of extinct species. "With RNA, we can obtain direct evidence of which genes are 'turned on', offering a glimpse into the final moments of life of a mammoth that walked the Earth during the ... read more |

Scientists probe Tajik glacier for clues to climate resistanceKon Chukurbashi, Tajikistan (AFP) Oct 13, 2025 Greenland is melting, the Alps are melting and the Himalayas are melting - yet in one vast mountain region, huge glaciers have remained stable, or even gained mass, in recent decades. Can it last? ... more 
UK spearheads polar climate change research as US draws backHarwich, United Kingdom (AFP) Oct 12, 2025 Britain's flagship polar research vessel heads to Antarctica next week to help advance dozens of climate change-linked science projects, as Western nations spearhead studies there while the United States withdraws. ... more 
North American ice sheets caused majority of post-Ice Age sea-level riseNew Orleans LA (SPX) Oct 11, 2025 Melting ice sheets in North America were the primary cause of a dramatic global sea-level rise at the end of the last ice age, according to new research led by Tulane University and published in Nat ... more 
Patagonian ice sheet followed its own climatic rhythmBerlin, Germany (SPX) Oct 15, 2025 Patagonia's immense ice fields, stretching hundreds of kilometers along the Andes, are relics of a vast ice sheet that once blanketed southern South America. New research from the University of Brem ... more 
Researchers wake up microbes trapped in permafrost for thousands of yearsBoulder CO (SPX) Oct 06, 2025 In a new study, a team of geologists and biologists led by CU Boulder resurrected ancient microbes that had been trapped in ice - in some cases for around 40,000 years. The study is a showca ... more |

Carbon feedback loops could plunge Earth into deep freeze
Bremen, Germany (SPX) Oct 01, 2025 Until now, the slow weathering of silicate rocks has been considered the planet's primary climate regulator. Rain absorbs atmospheric carbon dioxide (CO2), dissolves exposed rocks, and carries dissolved calcium and captured carbon to the sea. There, mussels, corals, and other organisms use it to form shells and reefs, trapping the carbon in sediments for millions of years. "When the planet warms, rocks weather faster and absorb more CO2, allowing the Earth to cool down again," explains Dominik Hulse. ... read more
