• Slow loris feared extinct since 1930s rediscovered; over 90 found in Indonesia

  Wildlife rescue teams tracking nocturnal primates across Bangka island over a decade have confirmed a viable population remains despite heavy human encroachment. Encounters occurred largely in residential areas and plantations, revealing severe displacement while providing critical biological data. Conservationists now warn that long-term survival hinges on addressing major habitat loss driven by regional agriculture and resource extraction.

• Evidence of red blood cells seen in dinosaur fossil from Brazil

  Researchers examining the fossilized leg bone of a 115-million-year-old carnivorous predator discovered vascular canals containing cell-like shapes and chemical traces of heme. Found in a gypsum mine in northeastern Brazil, this specimen provides scientists with rare physical and molecular remnants of ancient biological material. The discovery pushes the boundaries of paleontology by demonstrating that certain biological markers can endure across immense geological timescales.

• Fossilised red blood cells found in 115m-year-old dinosaur’s bone, say scientists

  Researchers led by Curtin University examined the hind leg of an ancient Aratasaurus, uncovering preserved biological material inside ancient blood vessel channels. The discovery challenges established paleontological assumptions that organic compounds inevitably degrade within a million years. If confirmed, this molecular evidence could provide unprecedented insight into the metabolism, physical capabilities, and daily activity levels of predatory dinosaurs.
