Published Western science catches up with First Nations' medicinal use of ant honey



Scientists have discovered the honey produced by Australian ants possesses unique anti-microbial activity against bacteria and fungi that could make the liquid useful medicinally.
Published Missing island explains how endemic species on the Miyako Islands emerged



Miyako Islands are home to various native species of snake and lizards. How these species came to call these islands home has long puzzled scientists. A group of researchers have compiled the latest geological and biological data, proposing that an island once facilitated migration between Okinawa and Miyako Islands.
Published Brown widow spiders: Invasive species prosper in favorable habitats and from a lack of local predators



Lower parasitism and predation in urban habitats may contribute to the invasion success of brown widow spiders, according to new research.
Published Why computer security advice is more confusing than it should be


If you find the computer security guidelines you get at work confusing and not very useful, you're not alone. A new study highlights a key problem with how these guidelines are created, and outlines simple steps that would improve them -- and probably make your computer safer.
Published Scientists discover new isopod species in the Florida Keys



Scientists have discovered a new species of marine cryptofauna in the Florida Keys. Cryptofauna are the tiny, hidden, organisms that make up the majority of biodiversity in the ocean. The tiny crustaceans are the first new gnathiid isopod to be discovered from the Floridian ecoregion in 100 years and are named after singer-songwriter Jimmy Buffett.
Published Miocene period fossil forest of Wataria found in Japan



An exquisitely preserved fossil forest from Japan provides missing links and helps reconstruct a whole Eurasia plant from the late Miocene epoch.
Published Hidden cameras spot wildlife returning home after 2018 megafire



Researchers analyzed more than 500,000 motion-sensor camera trap images taken at a Northern California reserve in the years before and after the Mendocino Complex Fire to understand how the blaze impacted small- and medium-sized mammals. The study is one of the first to compare wildlife observations made before and after a megafire, and is also one of a limited number of studies to focus on the impacts of megafires on California's oak woodlands.
Published Japanese beetles could spread throughout Washington state, US, in 20 years



Without intervention, the colorful but devastating Japanese beetle could make its way across the evergreen state within two decades, according to a study of their potential dispersion. The iridescent, green-and-copper beetles damage plants by 'skeletonizing' their leaves, chewing up all the soft green parts between the veins. They eat over 300 plants and pose a serious threat to Washington agriculture as some of their favorite crops include grapes, hops and cherries. The study found that Japanese beetles would most likely thrive in the dry, agriculture-rich southeastern part of the state, where the first individuals were found three years ago. If they were to escape the quarantines in place in those areas, modeling shows they would likely spread throughout the region from Yakima to the Tri-Cities and north past Moses Lake. While the Cascades are a barrier, there are large areas of Western Washington that also have highly suitable habitat for Japanese beetles.
Published Form and function of island and mainland plants



Oceanic islands provide useful models for ecology, biogeography and evolutionary research. Many ground-breaking findings -- including Darwin's theory of evolution -- have emerged from the study of species on islands and their interplay with their living and non-living environment. Now, an international research team has investigated the flora of the Canary Island of Tenerife. The results were surprising: the island's plant-life exhibits a remarkable diversity of forms. But the plants differ little from mainland plants in functional terms. However, unlike the flora of the mainland, the flora of Tenerife is dominated by slow-growing, woody shrubs with a 'low-risk' life strategy.
Published Multiple uses of tropical mosaic landscapes



Many landscapes in the tropics consist of a mosaic of different types of land use. How people make use of these different ecosystems, with their particular plant communities, was unclear until now. Researchers, many of them from Madagascar, have now investigated this. When considering biodiversity, forests often get the most attention. But this research shows that rural households use a wide range of plant species and services provided by many nearby ecosystem types.
Published Small-winged and lighter colored butterflies likely to be at greatest threat from climate change


Small-winged and lighter colored butterflies likely to be at greatest threat from climate change. The family, wing length and wing colour of tropical butterflies all influence their ability to withstand rising temperatures, say ecologists. The researchers believe this could help identify species whose survival is under threat from climate change.
Published Alien invasion: Study reveals alarming economic costs of biological invasions to the European Union



Biological invasions are a major threat to ecosystems, biodiversity, and human well-being, resulting in ecosystem degradation and causing economic costs in the multi-trillions of euros globally. A study sheds light on the stark economic cost resulting from biological invasions in the European Union (EU).
Published Using AI to save species from extinction cascades



Algorithms can predict what movies or songs you might like, but they can also predict which species a predator would most likely eat. Researchers have been using machine learning to identify species interactions, and can predict which species are most likely to go extinct, so that intervention can be planned before this happens.
Published Marine fossils are a reliable benchmark for degrading and collapsing ecosystems



Humans began altering environments long before records were kept of the things that lived in them, making it difficult for scientists to determine what healthy ecosystems should look like. Researchers show the recent fossil record preserves a reliable snapshot of marine environments as they existed before humans.
Published Caterpillar venom study reveals toxins borrowed from bacteria



Researchers have found toxins in the venom of asp caterpillars are completely different to anything they have seen before in insects. Toxins in the caterpillar venom punch holes in cells the same way as toxins produced by disease-causing bacteria such as E. coli and Salmonella. Venoms are rich sources of new molecules that could be developed into medicines of the future, pesticides, or used as scientific tools.
Published Forest can adapt to climate change, but not quickly enough



America's forests have a tough time in store for them. Climate change is increasing temperatures and decreasing moisture levels across the country, not a winning combination for trees.
Published Study reveals how a tall spruce develops defense against hungry weevils



A study has identified genes involved in development of stone cells -- rigid cells that can block a nibbling insect from eating budding branches of the Sitka spruce evergreen tree. The insect's attack has stunted the growth of these forest giants.
Published Solving rare disease mysteries ... and protecting privacy


Researchers have demonstrated a new way of linking personal records and protecting privacy. The first application is in identifying cases of rare genetic disorders. There are many other potential applications across society.
Published Stressed for a bit? Then don't click it, cybersecurity experts advise



Workers feeling a specific form of stress are more likely than others to become the victims of a phishing attack, according to a new study.
Published Evaluating cybersecurity methods



Researchers created a generic framework that enables an engineer or scientist to evaluate the effectiveness of defense schemes that seek to limit a hacker's ability to learn secret information by observing the behavior of a victim computer program.
