Scientists discovered that melting permafrost triggers a natural process that pulls carbon dioxide from the air, sometimes removing more than the greenhouse gases released. This surprising geological effect could reshape how we understand climate change in frozen regions.
Scientists in Alaska discovered 26 new microbial species in 40,000-year-old permafrost that could revolutionize cold weather protection. The tiny organisms may lead to anti-icing coatings for planes and creams that prevent frostbite.
A 14,000-year-old wolf pup preserved in Siberian permafrost had eaten woolly rhinoceros meat before it died, and scientists just used that ancient meal to piece together the extinct giant's complete DNA. This breakthrough marks the first time researchers have reconstructed an entire genome from digestive tissue.
A new study shows Canada could remove five times its annual carbon emissions by planting trees along the northern edge of its boreal forest. The strategy could sequester almost 4 gigatons of carbon by 2100 while helping stabilize methane-releasing permafrost.
Army researchers discovered 26 never-before-seen microbe species in ancient Alaskan permafrost that could lead to frostbite-preventing creams and ice-resistant coatings. These tiny survivors have stayed alive in frozen ground for 40,000 years, and scientists are unlocking their secrets.
Scientists successfully grew a flowering plant from fruit frozen in Siberian permafrost for 32,000 years, shattering the previous longevity record by more than 10 times. The ancient seeds, buried by Ice Age squirrels, bloomed into flowers with surprising differences from their modern relatives.
Scientists discovered a treasure trove of ancient DNA, including from woolly mammoths, perfectly preserved in frozen squirrel droppings in Canada's Yukon. The findings offer an unprecedented window into how life evolved over hundreds of thousands of years.
A woman's leather boot from 2,300 years ago, decorated with crystals and beads, survived frozen in Siberia's mountains. The stunning footwear reveals how skilled ancient craftspeople were and hints at how nomadic societies showed status.

Researchers studying 17th-century whaler graves in the Arctic made a surprising discovery that's spurring urgent action to preserve history. Their work reveals how climate change is threatening to erase centuries of cultural heritage before it can be documented.
A rejected doctoral student watching a dog inspired a breakthrough that lets scientists recover DNA from dirt, unlocking secrets about ancient humans without needing rare fossils. Twenty years later, his "stupid idea" has transformed how we study human origins.
Scientists just proved renewable hydrogen systems can power research stations in Antarctica's extreme conditions. This breakthrough could bring clean energy to isolated communities worldwide.
Scientists discovered that freshwater lakes in Antarctica's volcanic craters aren't isolated—they connect to the ocean and respond to tides. This finding rewrites our understanding of water systems in polar regions.
Scientists successfully revived a microscopic animal frozen in Arctic ice for 24,000 years, and it immediately began reproducing. This breakthrough reveals new possibilities for understanding how life endures extreme conditions across vast stretches of time.
Over 5,700 Arizona students turned everyday frustrations into real inventions this year, from cat toys to robotic trash collectors. Their creations competed at Arizona State University in a statewide contest teaching kids to think like entrepreneurs.
Chilean and European scientists just validated renewable hydrogen energy systems at a research station in Antarctica, proving clean energy can work in Earth's harshest conditions. The breakthrough could revolutionize power solutions for isolated communities worldwide.
Scientists just validated renewable hydrogen energy systems in Antarctica's extreme conditions, proving clean power can work anywhere. This breakthrough could transform energy access for isolated communities worldwide.
A groundbreaking study reveals that strategic tree planting across Canada's northern boreal forest could remove five times the country's annual carbon emissions by 2100. The research offers a clear roadmap for Canada to achieve carbon neutrality while restoring vital forest ecosystems.
A beaver expert who consulted on Pixar's new film Hoppers reveals the surprisingly accurate science behind the movie's adorable dam builders. From "beaver butt juice" in your vanilla flavoring to why these 110-pound engineers could never be classroom pets, the real story is just as wild as the film.
Scientists in Canada's Yukon discovered a treasure trove of DNA up to 700,000 years old preserved in frozen squirrel droppings. The genetic material from woolly mammoths, wolves, and hundreds of plants offers an unprecedented window into Earth's ancient past.
A new study shows Canada could offset five times its annual emissions by planting trees at the northern edge of its boreal forest. The ambitious plan could remove up to 19.4 gigatons of CO2 by 2100, but success depends on choosing the right locations and protecting forests from wildfires.
