After 128 years of exploration, fossil excavation and investigation, Flinders University researchers have finally uncovered the skull of Australia’s own giant and charismatic megafauna bird—Genyornis newtoni. The only previously known skull for this species, reported in 1913, was heavily damaged and with little of the original bone remaining, not much could be deduced about the … Read more
A groundbreaking discovery by a team of paleontologists has unearthed the fossil of a colossal flying reptile from the Jurassic period, boasting an impressive wingspan exceeding three meters. This extraordinary find, unearthed in a gravel pit near Abingdon-on-Thames in Oxfordshire, ranks among the largest pterosaurs from that era ever discovered. The fossil, which comprises part … Read more
Small birds exhibit a remarkable range of flight styles, from the hovering maneuvers of hummingbirds to the bounding flight of sparrows and the soaring patterns of swifts and swallows. A recent study conducted by Cornell University researchers provides new insights into why these variations occur, suggesting that the structural evolution of wing bones in smaller … Read more
Trematodes, also known as flukes, are a class of parasitic flatworms with intricate lifecycles. This makes them interesting to scientists, but they are also significant to both human health and wildlife conservation. Trematodes can cause infection in humans when people eat food the flatworms have contaminated, including raw fish, crustaceans and vegetables. Though this is … Read more
Thousands of years ago, early hunter-gatherers returned regularly to Tagua Tagua Lake in Chile to hunt ancient elephants and take advantage of other local resources, according to a study published May 22 in the open-access journal PLOS ONE by Rafael Labarca of the Pontifical Catholic University of Chile and colleagues. Multiple archaeological sites are known … Read more
A team of evolutionary biologists at Harvard University, in collaboration with researchers from the Max Planck Institute for Biological Intelligence, East Carolina University, Osaka University, and the University of Toronto, has successfully reconstructed the genome of an extinct flightless bird known as the little bush moa. This significant breakthrough, published in the journal Science Advances, … Read more
In a behavioral experiment, crows were able to learn to produce a set number of calls. This involves them planning in advance. From the sound of the first call in a numerical sequence, it is possible to predict how many calls the crows will make. A research team consisting of Dr. Diana A. Liao, Dr. … Read more
Aquatic biology is a branch of biology that focuses on the study of life in water environments, encompassing a wide range of organisms, ecosystems, and processes that thrive in aquatic habitats. From the smallest microorganisms to the largest marine mammals, aquatic biology explores the diversity, adaptations, interactions, and ecological dynamics of aquatic life across freshwater, … Read more
Comparative anatomy is a branch of biology that involves the study of anatomical structures and systems across different species to understand evolutionary relationships, adaptations, functional morphology, and biological diversity. By comparing the anatomy of organisms from various taxonomic groups, researchers can gain insights into evolutionary patterns, developmental processes, physiological functions, and ecological adaptations that have … Read more
Animal ecology is a branch of biology that focuses on the study of animals in their natural habitats, examining their behaviors, interactions, adaptations, and population dynamics within ecological systems. By understanding how animals interact with their environment and with each other, animal ecologists gain insights into the ecological processes that shape ecosystems and influence biodiversity. … Read more
Zoology is the branch of biology that focuses on the study of animals, their behavior, physiology, classification, evolution, and distribution. It encompasses a vast array of organisms, from microscopic protozoa to large mammals, and explores the diversity of life on Earth. Zoologists investigate the structure, function, ecology, and behavior of animals in order to understand … Read more
The history of life on Earth spans billions of years, from the formation of our planet to the evolution of diverse life forms. This epic tale of biological evolution is intertwined with geological events, environmental changes, extinction events, and the emergence of complex organisms. The story of life on Earth is a testament to the … Read more
Animal physiology is the branch of biology that focuses on understanding the biological functions and adaptations of animals, ranging from microscopic organisms to complex multicellular organisms. It encompasses a wide range of topics, including cellular processes, organ systems, homeostasis, metabolism, reproduction, behavior, and adaptations to diverse environments. By studying animal physiology, scientists gain insights into … Read more
Botany, the scientific study of plants, encompasses a vast array of topics ranging from plant structure and function to their evolutionary history, ecological interactions, and economic importance. Plants are essential for life on Earth, serving as the primary producers in ecosystems, providing oxygen, food, shelter, and numerous other resources for humans and other organisms. The … Read more
Seagull species that have bigger brains are more likely to nest on coastal cliffs and may also be better adapted to breed in urban environments such as on the roofs of buildings. New research has found that more than half of cliff-nesting gull species have been recorded as nesting in towns and cities, compared to … Read more
When hunting for mice in winter, red and Arctic fox are known to plunge headfirst at speeds of 2–4 meters per second, but their sharp noses reduce the impact force in snow and protect them from injury, according to a new Cornell University study. The fundamental research sheds light on the biomechanics of the unique … Read more
Evolutionary theory, anchored in Charles Darwin’s seminal work “On the Origin of Species,” represents one of the most profound and influential concepts in the history of biology. Darwin’s theory revolutionized our understanding of the natural world, providing a unifying framework for explaining the diversity of life, the mechanisms of evolutionary change, and the interconnectedness of … Read more
Researchers Kazuaki Takasan and Kyogo Kawaguchi of the University of Tokyo with Kyosuke Adachi of RIKEN, Japan, have demonstrated that ferromagnetism, an ordered state of atoms, can be induced by increasing particle motility and that repulsive forces between atoms are sufficient to maintain it. The discovery not only extends the concept of active matter to … Read more
What can be done when one threatened animal kills another? Scientists studying critically endangered lemurs in Madagascar confronted this difficult reality when they witnessed attacks on lemurs by another vulnerable species, a carnivore called a fosa. This dynamic can be particularly complex when the predation occurs in an isolated or poor-quality habitat, according to research … Read more
