A recent study published in Scientific Reports reveals that shotgun sequencing, a favored method for measuring microbial biodiversity, is not as accurate as once thought. Amplicon sequencing, on the other hand, revealed more than twice the number of phyla and 27% more families in water samples from Brazil's major river floodplain systems.
Researchers have revised the understanding of a large group of Neotropical 'club-tailed' scorpions, revealing two new genera and three new species. The findings provide insight into the evolution and classification of these ancient arthropods, which are among the oldest living terrestrial species on Earth.
A new species of troodontid theropod has been identified and named Albertavenator curriei in honour of renowned Canadian palaeontologist Dr. Philip J. Currie. The discovery was made by ROM scientists who compared the dinosaur's skull bones to those of its close relative Troodon.
A rare fossil of Eusaurosphargis dalsassoi has revealed the animal's complete skeleton, providing a clear idea of its anatomy and probable lifestyle. The species is thought to have been adapted for life on land, contradicting earlier assumptions that it was aquatic.

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.

A new fossil discovery in New Mexico reveals that the earliest primates, known as plesiadapiforms, were adapted to living in trees. The 62-million-year-old skeleton shows flexible joints for climbing and clinging to branches, contradicting previous theories of terrestrial lifestyles.
Research on La Brea Tar Pits fossils suggests LA's climate has remained relatively stable for 50,000 years. The study analyzed ground and darkling beetle fossils using radiocarbon dating, revealing three semi-continuous age ranges that indicate a warmer and drier climate similar to today.
New research from the Smithsonian reveals that whales started bulking up around 2-3 million years ago, when increasing ice sheets concentrated prey in the oceans. This shift allowed for larger body sizes to evolve, as filter-feeding became more efficient with access to dense prey patches.
Researchers found that distractions detract from the experience of beauty, but sensuous pleasures can also be beautiful. Participants rated their experience of each object on a four-point beauty scale and reported personal meaning behind certain experiences.
A study by Florida Museum of Natural History found that noise pollution from gas compressors significantly decreases the populations of certain insects and spiders, while increasing others. This shift in arthropod communities could have larger-scale ecological consequences.

From structured monitoring to 'mass participation' projects using smartphones, citizen science is becoming increasingly popular and accessible.
A paleontologist at the Canadian Museum of Nature argues that decades of research on sex differences among dinosaurs is based on flawed data. The scientist's report highlights issues with small sample sizes and statistical analysis methods, leading to invalid conclusions about sexual dimorphism in dinosaurs.
A new study from the University of Cambridge and Natural History Museum proposes a major overhaul of the traditional dinosaur classification system. The researchers conclude that Ornithischia and Theropoda should be grouped together under the name Ornithoscelida, with dinosaurs potentially originating in the northern hemisphere.
A new study confirms that sharks arose from a group of bony fishes called acanthodians, using an extraordinarily well-preserved fossil of an ancient sharklike fish. The research identifies the fossil as an important transitional species pointing to sharks as acanthodians' living descendants.

A new study found that Stomiidae family of deep-sea fishes have a flexible connection between their first vertebra and the back of their head, allowing them to open their mouths wide for consuming large prey. This unique joint may enable fish to consume larger prey due to its additional flexibility.

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.
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.
Scientists have determined that hyoliths, extinct cone-shaped animals with mineralized external skeletons, are more closely related to brachiopods than molluscs. The discovery sheds light on the evolutionary history of these ancient creatures and their place in the tree of life.
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.
The National Endowment for the Humanities has awarded grants to University of Houston faculty members Rex Koontz and Julie Tolliver.
