Lessons from extinction could help protect the bears of today. New research reveals that the now-extinct cave bear was much more adaptable than once thought yet was still made extinct when faced with the combined pressures of climate change and human competition. This offers a stark warning for modern bear conservation strategies. /news/2025-08-lessons-cave-extinction-endangered.html Plants & Animals Paleontology & Fossils Wed, 20 Aug 2025 14:43:04 EDT news674919782 An international team of scientists, led by Northwestern University astrophysicists, has detected a never-before-seen type of exploding star, or supernova, that is rich with silicon, sulfur and argon.
