And then another. They're bubbles of methane, a potent heat-trapping gas made from decomposing plants and animals that had once been stuck in Alaska's frigid permafrost. But that frozen ground is thawing because the Arctic is warming four times faster than the rest of the globe. For thousands of years that frozen ground stored dead plants and animals, but the accelerating thaw is allowing them to decay into methane and carbon dioxide. https://phys.org/news/2026-10-gas-frozen-arctic-ground-slowly.html Environment Sun, 04 Oct 2026 12:20:01 EDT news710069106 Researchers at the University of Kentucky Martin-Gatton College of Agriculture, Food and Environment (CAFE) have discovered that a fungus living inside a common Kentucky woodland grass produces a rare combination of chemicals that likely helps protect the plant from hungry insects. https://phys.org/news/2026-09-fungus-kentucky-forest-grass-rare.html Ecology Tue, 29 Sep 2026 13:40:01 EDT news709895762 At the end of the last ice age, early humans crisscrossed the Americas following seasons, rivers and game, often with a trusty spear in hand. Nearly 13,000 years later, archaeologists are using those spearheads to study how America's first inhabitants understood risk. https://phys.org/news/2026-09-ancient-spearheads-reveal-ice-age.html Archaeology Mon, 28 Sep 2026 17:20:05 EDT news709824662 When an abstract-looking ivory artifact emerged from the Hohle Fels cave in southern Germany in 2015, archaeologists didn't know quite what to make of it. Previously, the same cave had yielded what may be the world's oldest musical flutes, as well as one of humanity's earliest pieces of figurative art, the iconic Venus of Hohle Fels. At first glance, this strange new discovery—a 20-centimeter (8-inch) rod perforated with four small holes—seemed comparatively unspectacular. https://phys.org/news/2026-09-rope-twine-thread-invisible-technologies.html Archaeology Tue, 22 Sep 2026 09:20:04 EDT news709286574 Intricate designs engraved across the surface of 18,000-year-old female figurines carved from mammoth ivory were inspired by the distinctive growth patterns visible in the tusks, a new study published in the journal npj Heritage Science has revealed. https://phys.org/news/2026-09-ice-age-carvers-mammoth-tusk.html Archaeology Wed, 16 Sep 2026 12:40:02 EDT news708770524 African wild dogs (Lycaon pictus) travel incredibly long distances to search for a mate and new places to breed.

Previous genetic studies had left open the question of whether their genetic diversity emerged in high-latitude areas, like that of woolly mammoths, but a new analysis of ancient DNA and habitat models covering the past 500,000 years has revealed a different story. https://phys.org/news/2026-09-history-woolly-rhinos-werent-creatures.html Evolution Mon, 14 Sep 2026 11:30:01 EDT news708600903 Deep within an ancient sinkhole lie the remains of dozens of mammoths, prehistoric wanderers who waded into the warm springs to their deaths. These deaths had long been accepted as having occurred roughly 26,000 years ago, but new dates published in the journal Quaternary Research suggest these ice-age giants were more than 160,000 years old. https://phys.org/news/2026-09-luminescence-dating-age-south-dakota.html Plants & Animals Sun, 13 Sep 2026 12:40:02 EDT news708253643 With their slender bodies and long front legs, Miracinonyx trumani—often nicknamed the "American cheetah"—was long thought to be a North American analog of the African big cat. But in a new study published in the journal Current Biology, researchers reveal that the extinct cat was more closely related to pumas. Some populations living near the Arctic preyed almost exclusively on fish, challenging the long-held assumption that these "cheetahs" chased fast-running prey, such as pronghorns. https://phys.org/news/2026-09-extinct-american-cheetah.html Evolution Sun, 06 Sep 2026 11:00:01 EDT news707573172 As climate change makes extreme weather more frequent and intense, floods, heat waves, droughts, wildfires and storms are increasingly disrupting roads, railways, airports and waterways.

The results of the study, published in Current Biology, show that, in contrast to the sex ratio among naturally occurring woolly mammoth remains, large bone accumulations associated with ancient human activity are dominated by females. https://phys.org/news/2026-07-ancient-dna-reveals-ice-age.html Paleontology & Fossils Thu, 30 Jul 2026 11:00:09 EDT news704463301 Excavations at Hohle Fels Cave in the UNESCO World Heritage area of the Swabian Jura in southwestern Germany have again yielded two spectacular 40,000-year-old depictions of birds carved from mammoth ivory. The two figurines are the smallest discovered so far and are the size of a thumbnail, while still including many details. These remarkable finds come from the rich Aurignacian layers at Hohle Fels, which have produced some of the oldest figurative art known and date to the initial arrival of modern humans in the Upper Danube region. https://phys.org/news/2026-07-ice-age-artists-thumbnail-size.html Archaeology Wed, 29 Jul 2026 17:40:01 EDT news704550903 SpaceX's mammoth Starship rocket blasted off Friday on another test flight stretching halfway around the world, this time releasing 20 of the most advanced Starlinks. https://phys.org/news/2026-07-spacex-starship-flight-advanced-starlinks.html Space Exploration Sat, 25 Jul 2026 13:15:07 EDT news704204084 With their ability to use tools, remember faces and even learn how to communicate with humans through sign language, nonhuman primates are considered to be among the smartest creatures on Earth. However, some concepts—geometry, for instance—have traditionally been thought of as beyond the abilities of humanity's closest cousins. https://phys.org/news/2026-07-children-monkeys-common-geometry.html Plants & Animals Mon, 20 Jul 2026 15:00:11 EDT news703766521 Permafrost usually hits the news as a hazard, a planetary risk. When this ice-rich ground thaws, it damages roads and building foundations. It drains lakes and tips trees into drunken forests. It releases greenhouse gases that have been locked in carbon-rich soils for thousands of years, amplifying warming and driving further thaw. https://phys.org/news/2026-07-earth-deep-memory-arctic-permafrost.html Earth Sciences Thu, 09 Jul 2026 14:40:01 EDT news702820801 When Dolly the sheep—the first cloned mammal—was born 30 years ago, she became one of the most famous animals in science history. Her arrival sparked predictions of a sci-fi future filled with cloned pets, cloned humans and even resurrected extinct animals like the wooly mammoth. But the reality of cloning has turned out to be much more complicated. https://phys.org/news/2026-07-years-dolly-sheep-born-cloning.html Biotechnology Wed, 08 Jul 2026 09:20:01 EDT news702720661 New research led by a University of Alaska Fairbanks archaeologist reveals that the earliest Native Americans had highly specialized diets, primarily hunting the largest animals on the landscape, and they targeted these megafauna consistently from Alaska to South America. https://phys.org/news/2026-07-earliest-americans-specialized-megafauna-alaska.html Archaeology Wed, 01 Jul 2026 19:20:04 EDT news702144361 There are currently 15 well-documented Late Pleistocene localities in North America in which Clovis points are found associated with proboscidean remains (of mammoth, mastodon and gomphothere). Archaeologists routinely assume these localities represent evidence that Clovis people hunted these multi-ton animals, and in turn invoke that evidence to claim humans had a role in the extinction of these large mammals. https://phys.org/news/2026-06-clovis-foragers-late-pleistocene-north.html Archaeology Wed, 01 Jul 2026 09:00:04 EDT news702027121 Archaeologists have long pictured prehistoric hunters taking down mammoths and other megafauna using the atlatl, a handheld spear-throwing device that uses leverage to achieve greater velocity and force when throwing darts. In particular, use of the atlatl was thought to be common in the Clovis culture in North America, which occurred roughly between 13,340 and 12,710 years ago. However, new research, published in the journal Proceedings of the National Academy of Sciences, suggests that the atlatl probably didn't exist in the region until much later. https://phys.org/news/2026-06-iconic-spear-device-wasnt-prehistoric.html Archaeology Tue, 30 Jun 2026 11:20:04 EDT news702033159 Roughly 27,500 years ago, a 15-year-old boy was brutally mauled by a bear in Arene Candide in what is now Liguria, Italy.
