Published Artificial intelligence speeds up heart scans, saving doctors' time, and could lead to better treatment for heart conditions
(via sciencedaily.com) Original source Researchers have developed a groundbreaking method for analysing heart MRI scans with the help of artificial intelligence, which could save valuable time and resources, as well as improve care for patients.
Published A stealth fungus has decimated North American bats but scientists may be a step closer to treating white-nose syndrome
(via sciencedaily.com) Original source An invasive fungus that colonizes the skin of hibernating bats with deadly consequences is a stealthy invader that uses multiple strategies to slip into the small mammals' skin cells and quietly manipulate them to aid its own survival. The fungus, which causes the disease white-nose syndrome, has devastated several North American species over the last 18 years.
Published Muscle machine: How water controls the speed of muscle contraction
(via sciencedaily.com) Original source The flow of water within a muscle fiber may dictate how quickly muscle can contract, according to a new study.
Published Hatcheries can boost wild salmon numbers but reduce diversity, studies find
(via sciencedaily.com) Original source The ability of salmon hatcheries to increase wild salmon abundance may come at the cost of reduced diversity among wild salmon, according to a new study.
Published Introducing co-cultures: When co-habiting animal species share culture
(via sciencedaily.com) Original source Cooperative hunting, resource sharing, and using the same signals to communicate the same information -- these are all examples of cultural sharing that have been observed between distinct animal species. In a new article, researchers introduce the term 'co-culture' to describe cultural sharing between animal species. These relationships are mutual and go beyond one species watching and mimicking another species' behavior -- in co-cultures, both species influence each other in substantial ways.
Published Mapping the world's fungi from air samples
(via sciencedaily.com) Original source Researchers have found that the key to a quick and cost-effective mapping of biodiversity has been right in front of our eyes all along, but at the same time invisible -- i.e., in the air that surrounds us.
Published Blood fat profiles confirm health benefits of replacing butter with high-quality plant oils
(via sciencedaily.com) Original source Switching from a diet high in saturated animal fats to one rich in plant-based unsaturated fats affects the fat composition in the blood, which in turn influences long-term disease risk. A study shows that it is possible to accurately measure diet-related fat changes in the blood and directly link them to the risk of developing cardiovascular disease and type 2 diabetes.
Published Air pollution harms pollinators more than pests, study finds
(via sciencedaily.com) Original source Pollinators experienced a 39-percent decline in foraging efficiency after being exposed to elevated air pollution levels. In contrast, plant-eating aphids and other pests were not significantly impacted.
Published Urban seagulls still prefer seafood
(via sciencedaily.com) Original source Seagull chicks raised on an 'urban' diet still prefer seafood.
Published A new species of extinct crocodile relative rewrites life on the Triassic coastline
(via sciencedaily.com) Original source The surprising discovery of a new species of extinct crocodile relative from the Triassic Favret Formation of Nevada, USA, rewrites the story of life along the coasts during the first act of the Age of Dinosaurs. The new species Benggwigwishingasuchus eremicarminis reveals that while giant ichthyosaurs ruled the oceans, the ancient crocodile kin known as pseudosuchian archosaurs ruled the shores across the Middle Triassic globe between 247.2 and 237 million years ago.
Published Researchers customize AI tools for digital pathology
(via sciencedaily.com) Original source Scientists developed and tested new artificial intelligence (AI) tools tailored to digital pathology--a rapidly growing field that uses high-resolution digital images created from tissue samples to help diagnose disease and guide treatment.
Published Researchers listen to the hearts of bats in flight
(via sciencedaily.com) Original source Unique recordings show that bats can ramp up heart rate from 6 to 900 b.p.m within minutes.
Published Researchers introduce generative AI for databases
(via sciencedaily.com) Original source Researchers have developed an easy-to-use tool that enables someone to perform complicated statistical analyses on tabular data using just a few keystrokes. Their method combines probabilistic AI models with the programming language SQL to provide faster and more accurate results than other methods.
Published Global database reveals large gaps in our knowledge of four-footed animals
(via sciencedaily.com) Original source Researchers developed TetrapodTraits -- a global database of animals with four feet -- which can now be applied for better ecology, evolution and conservation research.
Published Groundbreaking study reveals oceanic seabirds chase tropical cyclones
(via sciencedaily.com) Original source A new study reveals that the rare Desertas Petrels (Pterodroma deserta), a wide-ranging seabird in the North Atlantic, exhibit unique foraging behaviors during hurricane season. Contrary to other pelagic seabirds, these petrels do not avoid intense tropical cyclones but instead exploit the dynamic conditions for their benefit, providing new insights into the impact of cyclones on open ocean marine life.
Published Cracking open a tasty menu for captive marsupials to sink their teeth into
(via sciencedaily.com) Original source From sifting through topsoil for native truffles to cracking open hard shells of seeds and nuts to munch on the tasty kernels, Australia bettongs and potoroos are described as 'ecosystem engineers' in a two-way relationship between their rich diet and environmental health. However, with native ecosystems and potoroid marsupial numbers in decline, ecology and evolution experts are working to understand how difficult it is to bite into the foods these leading foragers seek out.
Published Life underground suited newly discovered dinosaur fine
(via sciencedaily.com) Original source A newly discovered ancestor of Thescelosaurus shows evidence that these animals spent at least part of their time in underground burrows. The new species contributes to a fuller understanding of life during the mid-Cretaceous -- both above and below ground.
Published Study projects major changes in North Atlantic and Arctic marine ecosystems due to climate change
(via sciencedaily.com) Original source New research predicts significant shifts in marine fish communities in the North Atlantic and Arctic Oceans as a result of climate warming.
Published Scientists discover how to improve vaccine responses to potentially deadly bacterium
(via sciencedaily.com) Original source Researchers have taken a leap forward in understanding how we might fight back against the potentially deadly MRSA bacterium. They have shown in an animal model that targeting a key suppressive immune molecule (IL-10) during the delivery of a vaccine improves the ability of the vaccine to protect against infection.
Published Restored oyster sanctuaries host more marine life
(via sciencedaily.com) Original source Oysters sanctuaries in Chesapeake Bay are working for more than just oysters. Compared to nearby harvest areas, sanctuaries contain more abundant populations of oysters and other animal life--and the presence of two common parasites isn't preventing that.
