Research led by VladimĂ­r Sládek sheds new light on how bones age, questioning long-standing assumptions that sedentary lifestyles are the primary cause of weakening bone strength in modern humans. /news/2025-10-holocene-skeletal-samples-link-sedentary.html Other Paleontology & Fossils Fri, 10 Oct 2025 13:43:22 EDT news679322596 Hippos, today restricted to sub-Saharan Africa, survived in central Europe far longer than previously assumed. Analyses of bone finds demonstrate that hippos inhabited the Upper Rhine Graben sometime between approximately 47,000 and 31,000 years ago, well into the last ice age. An international research team led by the University of Potsdam and the Reiss-Engelhorn-Museen Mannheim with the Curt-Engelhorn-Zentrum Archäometrie have now published a study on this in the journal Current Biology. /news/2025-10-hippos-survived-europe-ice-age.html Plants & Animals Paleontology & Fossils Fri, 10 Oct 2025 11:35:04 EDT news679314902 A near-complete skeleton found on the UK's Jurassic Coast has been identified as a new and rare species of ichthyosaur—a type of prehistoric marine reptile that once ruled the ancient oceans. /news/2025-10-rare-jurassic-sword-dragon-prehistoric.html Paleontology & Fossils Fri, 10 Oct 2025 08:50:04 EDT news679305002 In the journal Childhood in the Past, Ph.D. candidate Duru YaÄźmur BaĹźaran published the results of an analysis of an over 900-year-old skeleton of a child.

VCP is a protein essential for breaking up stress granules and has been linked to neurodegenerative diseases. However, VCP has a protein partner, ASPL, whose role has been unclear until now. /news/2025-10-protein-sidekick-dual-roles-stress.html Cell & Microbiology Molecular & Computational biology Wed, 08 Oct 2025 15:56:03 EDT news679157761 During warmer periods of the Middle Pleistocene, ancient humans in Italy were in the habit of butchering elephants for meat and raw materials, according to a study published October 8, 2025 in the open-access journal PLOS One by Beniamino Mecozzi of Sapienza University of Rome, Italy and colleagues. /news/2025-10-early-humans-butchered-elephants-small.html Archaeology Wed, 08 Oct 2025 14:00:09 EDT news679070161 A pioneering liquid metal combination is shaping up as a potential secret weapon in the global fight against antimicrobial resistance, and promises to outlast existing implant materials. /news/2025-10-orthopedic-implants-aim-longer-liquid.html Bio & Medicine Nanomaterials Wed, 08 Oct 2025 11:17:03 EDT news679141021 Some colorful lizards and a mathematical formula from the finance sector have been used to build a new framework to model evolution. /news/2025-10-lizard-genetics-perspective-evolution.html Evolution Molecular & Computational biology Wed, 08 Oct 2025 04:00:01 EDT news679071461 Sometimes, the best way to achieve a big outcome is to start small.

This behavior appears to be fairly widespread among birds. What's unique about some larger bird species, like certain vultures, eagles, and falcons, is that the same nest is used for centuries if it continues to be in a safe space. Generations of birds will continue to occupy and add materials to these nests for hundreds of years. /news/2025-10-bearded-vulture-hoards-cultural-artifacts.html Ecology Paleontology & Fossils Thu, 02 Oct 2025 10:40:01 EDT news678619914 What did early humans like to eat? The answer, according to a team of archaeologists in Argentina, is extinct megafauna, such as giant sloths and giant armadillos. In a study published in the journal Science Advances, researchers demonstrate that these enormous animals were a staple food source for people in southern South America around 13,000 to 11,600 years ago. Their findings may also rewrite our understanding of how these massive creatures became extinct. /news/2025-10-early-humans-dined-giant-sloths.html Archaeology Thu, 02 Oct 2025 09:44:54 EDT news678617088 For the first time, a research team from the Senckenberg Center for Human Evolution and Paleoenvironment at the University of TĂĽbingen and the Schöningen Research Center have reconstructed the genomes of an extinct horse species, Equus mosbachensis, from the archaeological site of Schöningen in Lower Saxony, which is approximately 300,000 years old. /news/2025-10-year-genomes-history-schningen-horses.html Evolution Paleontology & Fossils Thu, 02 Oct 2025 09:10:07 EDT news678615002 Fungi are vital to natural ecosystems by breaking down dead organic material and cycling it back into the environment as nutrients.

The detectors identify muons—particles created when cosmic radiation collides with Earth's atmosphere, which penetrate the ground before losing their energy and coming to a stop. Thus, by detecting muons, archaeologists can map hidden voids such as tunnels and channels. /news/2025-09-underground-spaces-muon-technology-3d.html Archaeology Mon, 29 Sep 2025 16:10:06 EDT news678380785 Losing your baby teeth is a strange experience. The teeth gradually loosen until they're replaced by thicker, more durable and permanent ones. But humans aren't the only animals capable of shedding teeth. In fact, most mammals have two sets of teeth throughout their life.
