Plants and the animals that eat them have evolved together in fascinating ways, creating a dynamic interplay of survival strategies. Many plants have developed physical and chemical defenses to fend off herbivores. A well-known strategy in flowering plants is to produce nectar to attract “ant bodyguards.” Recent research explores the evolution of this same defense … Read more
Primates, including humans, have notably larger brains compared to most other mammals. For decades, scientists have speculated that diet, particularly the consumption of fruit, played a crucial role in the evolution of these larger brains. A groundbreaking study from the Max Planck Institute of Animal Behavior and the Smithsonian Tropical Research Institute now suggests that … 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
Published today in the Alcheringa: An Australasian Journal of Palaeontology, a groundbreaking study has unveiled evidence of an “Age of Monotremes” in Australia, unearthed by a collaborative team from the Australian Museum (AM), Museums Victoria, and the Australian Opal Centre. This discovery, spearheaded by Professor Tim Flannery, Honorary Associate of the Australian Museum, and Professor … 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
A team of paleontologists from the Museo Argentino de Ciencias Naturales Bernardino Rivadavia, Consejo Nacional de Investigaciones Científicas y Técnicas, and The Chinese University of Hong Kong has identified a new species of abelisauroid dinosaur. The species has been named Koleken inakayali. This groundbreaking discovery is published in the journal Cladistics. The fossilized remains of … 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
Bioenergy sorghum is an important resource for the production of biofuels and bioproducts and a critical component of a sustainable agricultural future. Researchers have been working hard to make this tall, drought-tolerant plant even more productive and resilient to harsh environmental conditions. But those efforts are hampered by a lack of knowledge about the inner … 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
Decision-making in social contexts is typically explained through psychological, social, and political lenses. However, groundbreaking research by Hilke Plassmann and her team from the Paris Brain Institute and the University of Bonn suggests that our gut microbiota might also play a crucial role. Their findings, published in the journal PNAS Nexus, reveal that changes in … Read more
An international team of scientists has uncovered toxic metals in mineral phosphate fertilizers worldwide by using a new tool to identify the spread and impact of such contaminants on soil, water resources, and food supply. “While mineral phosphate fertilizers are critical to boost global sustainable agriculture and food security, we found high levels of toxic … Read more
Proteins are molecular machines, with flexible pieces and moving parts. Understanding how these parts move helps scientists unravel the function a protein plays in living things—and potentially how to change its effects. Biochemists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory and colleagues at DOE’s Pacific Northwest National Laboratory (PNNL) have published a … Read more
Scattered across the Penobscot Experimental Forest are veritable treasure troves for its denizens, each containing riches beyond comprehension. These caches do not contain gold or jewels—they’re filled with eastern white pine seeds and were placed by a team of researchers at the University of Maine for one purpose: to catch furry thieves red-handed. Brigit Humphreys, … Read more
Bats, as the main predator of night-flying insects, create a selective pressure that has led many of their prey to evolve an early warning system of sorts: ears uniquely tuned to high-frequency bat echolocation. To date, scientists have found at least six orders of insects—including moths, beetles, crickets and grasshoppers—that have evolved ears capable of … Read more
Cellulose, which helps give plant cell walls their rigid structure, holds promise as a renewable raw material for biofuels—if researchers can accelerate the production process. Compared to the breakdown of other biofuel materials like corn, breaking down cellulose is slow and inefficient but could avoid concerns around using a food source while taking advantage of … Read more
Insects and microorganisms that feed on plants, cut up leaves, modify leaf tissue or produce leaf spots and other kinds of damage, are usually known as pests and considered harmful, yet interactions between plants and their natural enemies are important sources of biodiversity. In tropical forests, for example, these “pests” are part of large ecological … Read more
Chimpanzees continue to learn and hone their skills well into adulthood, a capacity that might be essential for the evolution of complex and varied tool use, according to a study published May 7 in the open-access journal PLOS Biology by Mathieu Malherbe of the Institute of Cognitive Sciences, France and colleagues. Humans have the capacity … Read more
Animal development, also known as embryonic development, encompasses the complex processes through which a single fertilized egg cell transforms into a multicellular organism with distinct tissues, organs, and body structures. This intricate journey involves cellular differentiation, tissue organization, morphogenetic movements, and regulatory mechanisms that orchestrate the formation of body axes, germ layers, organ systems, and … Read more
Microbial genetics is a specialized field within genetics that focuses on the study of genetic mechanisms in bacteria and archaea, collectively referred to as microorganisms or microbes. These single-celled organisms play crucial roles in various ecosystems, contributing to nutrient cycling, biogeochemical processes, symbiotic relationships, and human health. Microbial genetics explores the diversity, evolution, regulation, and … Read more
Systems biology is an interdisciplinary field that seeks to understand biological systems as integrated networks of components, processes, and interactions, rather than isolated parts. It combines principles from biology, mathematics, computer science, engineering, and other disciplines to analyze complex biological phenomena at multiple scales, from molecular and cellular levels to tissues, organs, organisms, populations, and … Read more
