The Vatican has the world’s highest Pope density: 2.27 Popes/km². May not sound like much, but scaled to the size of Russia, we’d end up with c. 38 M Popes. At this point, running the Catholic Church might become quite complex. (Yes!, you guessed it. Today I'm "working" from home).

A biodiversidade brasileira está sendo cada vez mais registrada! 🌿📊  Entre 2022 e 2025, o número de registros de espécies no país cresceu 65,49%, chegando a 37,5 milhões. Os dados fazem parte da nova Avaliação da Biodiversidade do IBGE.

“Units of the NIH are privately directing grantees to request permission in advance for any co-authorship with a scholar affiliated with a foreign institution, even if all the work was done in the United States.” Grantees also told to remove papers with foreign authors from progress reports.

Diplozoon paradoxum Members of the genus Diplozoon are a striking group of monogenean parasites, typically found on the gills of freshwater and marine fish. They begin as separate, free-living juveniles, who later physically interlock with a partner to form a lifelong union ❤️

Our PhD student Kennedy Orwa, who studies applications of AI to health care, was hastily deported today to Kenya along with his 13-year-old son without opportunity to speak to legal counsel. King 5 reports that he held a valid visa that was rescinded without explanation.

ChatBot: Do you think AI-generated encyclopedias can eventually match the reliability of human-curated ones, or is the "human in the loop" essential for truth? Me: I'm just a humble human reluctant to give my opinion to an AI-driven chatbot. ChatBot: Fair point! I’ll tip my digital hat to that.

Natural history museums are important biodiversity repositories for future generations. IMPACT will contribute specimens to European museum collections.

The fish louse Argulus coregoni, possibly one of the cutest freshwater parasites there is! This parasitic crustacean lives on freshwater fish where they feed on skin and mucus. Most commonly seen by trout anglers in late summer and autumn. Image: Arnstein Staverløkk Instagram @naturogbilde

Parasites of freshwater fish come in all shapes and sizes. IMPACT invites you to get to know some of the fascinating parasite species we know and love 🥰

El nou projecte MAReA de la #UV i la UIB estudiarà com es dispersen els patògens marins en entorns aqüícoles. 🧪 També combinarà ADN ambiental, anàlisi morfològica i dades oceanogràfiques per identificar reservoris i desenvolupar eines d’alerta primerenca.
