A study published in PLOS ONE found that adults rely more on top-down processing when viewing Van Gogh's paintings, focusing on less noticeable features after hearing descriptions. In contrast, children initially focus on standout features before being influenced by prior knowledge, making their attention shift to more subtle details.
Adult female praying mantises in the newly identified genus Hondurantemna chespiritoi have evolved to mimic a leaf by changing color to green and developing larger forewings. This unique camouflage strategy is distinct from that of males, which retain their brown coloration and stick-like body configuration.
Researchers at WMG University of Warwick used CT scanning technology to reveal five previously unseen teeth in the Megalosaurus jawbone, challenging previous restoration work. The scans also showed the extent of repairs, suggesting at least two phases of repair using different types of plaster.

Researchers discover Ruby Seadragons lack ornate leaf-like appendages, a feature previously considered distinguishing to all seadragon species. They also found that the fish have prehensile, curled tails, similar to those of seahorses and pipefish, which may aid in holding on to objects in high-surge waters.
Researchers have discovered a new species of ruby seadragon in the wild, showcasing its intense red color and distinctive features. The fish lives at depths of over 50 meters, beyond recreational diving limits, and relies on its red color for effective camouflage.

A new species of ground beetle, Bryanites graeffii, has been described from a 147-year-old specimen found in the Muséum national d'Histoire naturelle in Paris. The discovery sheds light on the impact of human activity on ecosystems and highlights the extinction of native insect species due to colonization by non-native species.
Research on dinosaur embryos shows that non-avian dinosaurs took 3-6 months to hatch, similar to reptiles. This finding suggests prolonged incubation may have affected their ability to compete with rapidly evolving bird populations, contributing to the mass extinction event.
Scientists have discovered a new species of coral-reef fish, Tosanoides obama, that lives exclusively within the Papahānaumokuākea Marine National Monument. The fish is special because it is the only known species of coral-reef fish endemic to the Monument.
