Scientists from the Canadian Museum of Nature have announced the discovery and description of an extinct rhinoceros from the Canadian High Arctic. The nearly complete fossil skeleton of the new species was recovered from the fossil-rich lake deposits in Haughton Crater on Devon Island, Nunavut and is the most northerly rhino species known. Rhinoceroses have an evolutionary history that spanned over 40 million years, encompassing all continents except South America and Antarctica. The “Arctic rhino” lived about 23 million years ago, during the Early Miocene and is most closely related to other rhino species that thrived in Europe millions of years earlier. The paper also describes that the new Arctic species migrated to North America across a land bridge that may have been a passage for terrestrial-mammal dispersal millions of years later than previous evidence suggests.

The EU-funded SpongeBoost project invites both organisations and private individuals, aimed at restoring sponge landscapes across Europe, to apply for the "SpongeBooster of the Year 2026" award. The winning project will receive recognition and visibility for its work during a field trip to its research area.

A study led by researchers from the University of Sydney and the University of Adelaide has revealed how the breakup of an ancient supercontinent about 1.5 billion years ago transformed Earth’s surface environments, triggering the conditions that supported oxygen-rich oceans and the appearance of the first eukaryotes, the ancestors of all complex life.

Sporadic-E is a phenomenon that occurs in the ionosphere that can disrupt radio communications. Through simulations, researchers have found that rising CO₂ levels in our atmosphere could lead to sporadic-E becoming stronger, occur at lower altitudes, and persist longer at night.

Egyptian paleontologists have discovered the earliest known member of Dyrosauridae — a group of long-snouted, coastal and marine Crocodyliforms— in the Western Desert of Egypt. The new species, Wadisuchus kassabi, lived around 80 million years ago and bridges a crucial fossil gap in the early evolution of marine crocs. The well-preserved skull and jaws, described in The Zoological Journal of the Linnean Society, reveal transitional features in the development of the dyrosaurid snout and skull adaptations. The findings point to North Africa — particularly Egypt’s Quseir Formation — as the birthplace of Dyrosauridae before their global expansion following the dinosaur extinction.
