Published Pseudoscorpions of Israel: Two new family records discovered
(via sciencedaily.com) Original source A recent study has unveiled two previously undiscovered families of Pseudoscorpions in Israel. Positioned at the convergence of three continents, Israel's distinct biodiversity has undergone systematic revision, resulting in an updated checklist featuring 61 pseudoscorpion species across 28 genera and fourteen families. This pioneering research includes the introduction of the first illustrated identification key, based on morphological characters, accompanied by distribution maps. Notably, the study highlights the discovery of two new family records in Israel -- Syarinidae and Cheiridiidae -- both with a cosmopolitan distribution, including in the Mediterranean region. The findings significantly enhance our comprehension of regional biodiversity, offering crucial resources for forthcoming ecological, taxonomical and conservation endeavors. Furthermore, several undescribed species identified in this paper will be comprehensively described in separate publications, further advancing the field of pseudoscorpion taxonomy.
Published New scientific study reveals the crucial role of herbivorous fishes and sea urchins in restoring Caribbean coral reefs
(via sciencedaily.com) Original source A new study presents crucial findings on the feeding preferences of herbivorous fishes and the sea urchin Diadema antillarum in Little Cayman. The study sheds new light on the dynamics of these herbivores and their impact on the resilience of Caribbean coral reefs.
Published Surveilling wetlands for infectious bird flu -- and finding it
(via sciencedaily.com) Original source Recently, morning omelets and holiday dinners have gotten more expensive. One likely cause is bird flu, outbreaks of which led to the deaths of millions of chickens and turkeys from infection or culling in 2022, according to the U.S. Department of Agriculture, and which still demands rigorous monitoring of wild populations. Now, researchers have developed a method that detected infectious bird flu virus in wetlands frequented by waterfowl.
Published Colliding ribosomes activate RNA repair
(via sciencedaily.com) Original source Researchers discover how ribosomes contribute to the recognition and removal of RNA crosslinking damage.
Published Unexpected discovery opens bioengineering opportunities for human and plant health
(via sciencedaily.com) Original source An unexpected genetic discovery in wheat has led to opportunities for metabolic engineering of versatile compounds with potential to improve its nutritional qualities and resilience to disease.
Published Genetic discovery promises high-iron vegetables and cereals
(via sciencedaily.com) Original source A genetic breakthrough has opened new opportunities for iron-fortified vegetables and cereal crops to help address the global health issue of anemia.
Published Novel C. diff structures are required for infection, offer new therapeutic targets
(via sciencedaily.com) Original source Newly discovered iron storage 'ferrosomes' inside the bacterium C. diff -- the leading cause of hospital-acquired infections -- are important for infection in an animal model and could offer new targets for antibacterial drugs. They also represent a rare demonstration of a membrane-bound structure inside a pathogenic bacterium, upsetting the biological dogma that bacteria do not contain organelles.
Published New deep learning AI tool helps ecologists monitor rare birds through their songs
(via sciencedaily.com) Original source Researchers have developed a new deep learning AI tool that generates life-like birdsongs to train bird identification tools, helping ecologists to monitor rare species in the wild.
Published Previously unknown luminescence revealed in ten deep sea species and an order of sea cucumbers
(via sciencedaily.com) Original source Researchers present evidence of previously unknown luminosity in 10 deep-sea species, suggesting underestimated diversity. These new discoveries include a member of the order Molpadia, which was previously thought not to be luminescent. The authors stress the importance of considering the ecological role of bioluminesence and the need for conservation.
Published Dangerous bee virus less deadly in at least one US forest
(via sciencedaily.com) Original source Researchers have found that the deadly deformed wing virus (DMV) in bees may have evolved to be less deadly in at least one U.S. forest. The findings could have implications for preventing or treating the virus in managed colonies, researchers said.
Published Geese 'keep calm and carry on' after deaths in the flock
(via sciencedaily.com) Original source Canada geese strengthen existing friendships and forge a few new connections after losing close associates from their flock, new research shows.
Published Non-native species likely to continue spreading in North America, Australia and Europe
(via sciencedaily.com) Original source Naturalized species, which are not native but have established themselves in new locations, have the potential to spread even further to suitable habitats in many parts of the world, reports a new study.
Published Shedding new light on sugars, the 'dark matter' of cellular biology
(via sciencedaily.com) Original source Chemists have developed a new tool for detecting interactions between sugars and lectins, a discovery that could help in the fight against diseases like cancer.
Published Forecasting microbiomes for sustainability and health
(via sciencedaily.com) Original source Microbial communities, or microbiomes, are essential for safeguarding human and environmental health through the most widely used biotechnological process on our planet: biological wastewater treatment. However, the process itself is subject to constant changes, difficult to sustain over long periods of time and emits significant amounts of greenhouse gases.
Published Research provides crucial insights into moss growth under elevated CO2 levels that may benefit climate change models
(via sciencedaily.com) Original source Approximately 12,000 species of mosses exist and cover close to four million square miles of earth, equivalent to the size of Canada, and are ecologically and evolutionarily important. Mosses play an essential role in rainwater retention, decreasing plant pathogens and increasing carbon sequestration in soil, thus improving the overall soil health. Mosses also protect long-term carbon storage systems, such as bogs and permafrost.
Published How tiny hinges bend the infection-spreading spikes of a coronavirus
(via sciencedaily.com) Original source Far from being stiff and pointy, a coronavirus's infectious spikes are shaped like chicken drumsticks with the meaty part facing out, and the meaty part can tilt every which way on its slender stalk. A new study suggests that disabling those hinges could block infection.
Published A tale of two proteins: Fundamental research could make growing better crops like clockwork
(via sciencedaily.com) Original source Rhomboid-like protein 10, or RBL10, is thought to be an enzyme that degrades other proteins in the chloroplast membrane, but its function is largely unknown. Researchers are studying how RBL10 affects photosynthetic membrane lipid metabolism, an essential process in photosynthesis.
Published Hormonal contraceptives in teens may alter risk assessment, rat study suggests
(via sciencedaily.com) Original source Hormonal contraceptives taken by adolescents may influence development of the brain in a way that alters the recognition of risks, a new study in rats suggests.
Published Evolution of taste: Early sharks were able to perceive bitter substances
(via sciencedaily.com) Original source New genetic data show that humans and sharks share bitter taste receptors, even though their evolutionary pathways separated nearly 500 million years ago.
