After 40,000 Years, Microbes Are Awakening From Thawing Permafrost
Waking the Long-Frozen Microbes: A Window into the Arctic’s Hidden Life In a discovery that blends microbiology with climate science, researchers report that microbes buried in Alaskan permafrost for tens of thousands of years are reawakening as the freezer-like ground thaws. Some of these organisms have been trapped for as long as 40,000 years, yet…

Permafrost Microbes Awake After 40,000 Years
Ancient life in thawing ground raises climate questions In a striking reminder that the Arctic is not just cold but also a living archive, researchers report that microbes trapped in Alaskan permafrost for up to 40,000 years have reawakened. The discovery comes from samples taken from a deep, dark corridor known as the Permafrost Tunnel…

Permafrost Awakening: Microbes Reignite Arctic Emissions
Ancient Life Comes Back to Life in a Modern Climate Experiment In a startling glimpse of how the Arctic may respond to a warming world, researchers have revived microbes trapped in permafrost for up to 40,000 years. The study, conducted with samples from a deep underground Permafrost Tunnel Research Facility near Alaska, shows that frozen…

Reindeer and Carbon: Finland’s Forest Carbon Stabilizers
Reindeer and the carbon cycle in Finland’s north Not all climate heroes wear capes. Some sport antlers. A recent study published in Science of the Total Environment shows that reindeer grazing in Finland’s northern forests may help stabilise the carbon stored in soil and understory vegetation. By grazing through snow-covered undergrowth, these arctic herbivores influence…

Ice-Gliding Diatoms: Arctic Motility at Record Low Temps
Across the Arctic ice, diatoms persevere in a world of brine channels and shimmering ice. Our study provides direct cellular observations of ice-dwelling diatoms within frozen matrices, revealing an unexpected capability: ice gliding. Unlike temperate diatoms, these Arctic relatives appear to navigate by gliding along icy substrates, a skill that opens access to light, nutrients,…
