Published Genetics provide key to fight crown-of-thorns starfish



Scientists are one step closer to combating coral-destroying crown-of-thorns starfish, following a study into the pest's genetics.
Published Researchers uncover what makes some chickens more water efficient than others



Research indicates a specially bred line of chickens could save growers thousands of gallons of water and thousands of pounds of food each month without sacrificing poultry health.
Published Century of statistical ecology reviewed



A special review examines highly-cited papers in statistical ecology. The review, which covers a century of research, details how models and concepts have evolved alongside increasing computational power.
Published First case of highly pathogenic avian influenza transmitted from cow to human confirmed



in March a farm worker who reported no contact with sick or dead birds, but who was in contact with dairy cattle, began showing symptoms in the eye and samples were collected by the regional health department to test for potential influenza A. Experts have now confirmed the first case of highly pathogenic avian influenza transmission from a mammal (dairy cow) to a human.
Published Cats purrfectly demonstrate what it takes to trust robots



Would you trust a robot to look after your cat? New research suggests it takes more than a carefully designed robot to care for your cat, the environment in which they operate is also vital, as well as human interaction.
Published World's largest hummingbird is actually two species



The Giant Hummingbird of western South America is not one species but two, according to an international group of researchers. The northern population stays in the high Andes year-round while the southern population migrates from sea level up to 14,000 feet for the nonbreeding months.
Published Fruit fly testes offer potential tool against harmful insects



A way to curb nagging insects has been flying under our radar -- an enzyme from fruit fly testes. The compound could control bugs that carry disease and harm crops by stunting their ability to procreate, researchers have found.
Published New work extends the thermodynamic theory of computation



Physicists and computer scientists have recently expanded the modern theory of the thermodynamics of computation. By combining approaches from statistical physics and computer science, the researchers introduce mathematical equations that reveal the minimum and maximum predicted energy cost of computational processes that depend on randomness, which is a powerful tool in modern computers.
Published New viruses that could cause epidemics on the horizon



Suddenly they appear and -- like the SARS-CoV-2 coronavirus -- can trigger major epidemics: Viruses that nobody had on their radar. They are not really new, but they have changed genetically. In particular, the exchange of genetic material between different virus species can lead to the sudden emergence of threatening pathogens with significantly altered characteristics.
Published Island birds more adaptable than previously thought



The researchers found that birds were more evolutionarily similar on smaller, more isolated islands than on larger, less remote places. The team had expected to find that forested areas had more numerous and more varied species of birds compared to farmland areas. But they were surprised to find that the opposite was true: Areas with farms and human settlements had more species of birds and greater diversity than forested areas.
Published Some varieties of annual flowers have a place in pollinator-friendly gardens



While wildflowers and perennials are a must for supporting pollinators, there's no denying the popularity of many annual flowers for their colorful, visual appeal. A new study suggests choosing the right varieties can give annual flowers a role in nourishing bees and other pollinating insects in home gardens. Researchers observed pollinators visiting the six most popular annual flower species in the U.S., finding significant variation in pollinator attractiveness between cultivars, even within the same flower species.
Published Prostate cancer study: More health benefits from plant-based diet



Men with prostate cancer could significantly reduce the chances of the disease worsening by eating more fruits, vegetables, nuts, and olive oil, according to new research.
Published New machine learning algorithm promises advances in computing



Systems controlled by next-generation computing algorithms could give rise to better and more efficient machine learning products, a new study suggests.
Published New sex-determining mechanism in African butterfly discovered



In a study of a species of African butterfly, researchers have discovered a previously undescribed molecular mechanism of how the sex of an embryo is initially specified.
Published AI advancements make the leap into 3D pathology possible



Researchers present Tripath: new, deep learning models that can use 3D pathology datasets to make clinical outcome predictions. The research team imaged curated prostate cancer specimens, using two 3D high-resolution imaging techniques. The models were then trained to predict prostate cancer recurrence risk on volumetric human tissue biopsies. By comprehensively capturing 3D morphologies from the entire tissue volume, Tripath performed better than pathologists and outperformed deep learning models that rely on 2D morphology and thin tissue slices.
Published New record holder for smallest dispersers of ingested seeds: Woodlice



Even bugs as small as woodlice can disperse seeds they eat, setting a new record for smallest animal recorded to do so. The discovery underscores the crucial yet often overlooked role that small invertebrates play in ecosystems.
Published Acceptance of animals in urban environments



How do city residents feel about animals in their immediate surroundings? A recent study shows how different the acceptance of various wild animals in urban areas is. Important factors are the places where the animals are found and their level of popularity -- squirrels and ladybugs come out on top here. The results have important implications for urban planning and nature conservation.
Published An AI leap into chemical synthesis



Scientists introduce a large language model-based AI system that revolutionizes chemistry by integrating 18 advanced tools for tasks like organic synthesis and drug discovery.
Published Emergency department packed to the gills? Someday, AI may help



Emergency departments nationwide are overcrowded and overtaxed, but a new study suggests artificial intelligence (AI) could one day help prioritize which patients need treatment most urgently.
Published Bee body mass, pathogens and local climate influence heat tolerance



How well bees tolerate temperature extremes could determine their ability to persist in a changing climate. But heat tolerance varies between and within populations, so entomologists examined bee physical traits to understand how these traits interact with environmental conditions, pathogens and other factors.
