14+ hour, 40+ min ago  (681+ words) Ancient DNA and protein analysis reveal that modern Old Irish Goats are closely related to Bronze Age populations. This continuity highlights both their historical importance and the need for conservation. New findings show that the Old Irish Goat is genetically…...

1+ day, 4+ hour ago  (849+ words) Researchers are uncovering how underground water systems sustain the Grand Canyon and how they are changing over time. All of that water originates from a single source: Roaring Springs, a cave-fed spring located on the North Rim. It can be…...

1+ day, 23+ hour ago  (348+ words) A new geological study reshapes the timeline of a major tectonic collision that helped form the Andes, suggesting key events occurred earlier than long assumed. The work, led by Victor Piedrahita (first author) and J. Li (corresponding author), focuses on rocks…...

2+ day, 53+ min ago  (526+ words) A new geodynamic model is reshaping how scientists understand supervolcanoes, revealing that their magma systems may be far more diffuse and dynamic than previously believed. Supervolcanoes'those that have produced supereruptions in the geological record'are often thought to contain long-lived, liquid-rich…...

2+ day, 15+ hour ago  (255+ words) A small fossil snake may hold outsized clues about snake evolution, behavior, and an ancient ecosystem that looked nothing like today's. A newly identified fossil snake from Wyoming is rewriting scientists' understanding of snake evolution. The species, named Hibernophis breithaupti,…...

2+ day, 15+ hour ago  (796+ words) A chance discovery inside a long-overlooked fossil has revealed an unexpected chapter in pterosaur evolution. Around 110 million years ago, two small pterosaurs about the size of modern seagulls were flying over a lake or river, likely searching for food or…...

5+ day, 6+ hour ago  (545+ words) Genetic changes enabled animals to repeatedly adapt from water to land, reshaping life on Earth. The question of how life first moved from water onto land continues to fascinate scientists. Early organisms would have faced entirely new environmental pressures outside…...

1+ week, 3+ day ago  (707+ words) Ancient fossils from South China reveal the earliest bony fishes and shed new light on how jaws, teeth, and key vertebrate features evolved before the major fish lineages diverged. A research team led by Profs. Min Zhu, Jing Lu, and…...

1+ week, 6+ day ago  (485+ words) New research may have solved a long-standing geological mystery in the United States that has puzzled scientists for more than 150 years. Scientists have spent more than a century trying to understand how the Green River, the largest tributary of the…...

1+ week, 6+ day ago  (795+ words) A new analysis of meteorite isotopes challenges long-held ideas about Earth's origins, suggesting our planet may have formed almost entirely from nearby material rather than distant sources. Planetary scientists have long debated the origin of the material that formed Earth....
