Published Captivating blue-colored ant discovered in India's remote Siang Valley
(via sciencedaily.com) Original source A new species of blue ant was discovered in Yingku village in Arunachal Pradesh, Northeastern India. It was named Paraparatrechina neela, after the word 'neela' which means blue in various Indian languages. Its unique blue coloration makes it stand out among other ant species.
Published A greener, more effective way to kill termites
(via sciencedaily.com) Original source Scientists have discovered a highly effective, nontoxic, and less expensive way to lure hungry termites to their doom.
Published Trout in mine-polluted rivers are genetically 'isolated'
(via sciencedaily.com) Original source Trout living in rivers polluted by metal from old mines across the British Isles are genetically 'isolated' from other trout, new research shows.
Published 'Ugly' fossil places extinct saber-toothed cat on Texas coast
(via sciencedaily.com) Original source This fossil looks like a lumpy, rounded rock with a couple of exposed teeth that are a little worse for wear, having been submerged and tumbled along the floor of the Gulf of Mexico for thousands of years before washing up on a beach. But when it was X-rayed a doctoral student saw there was more to the fossil that met the eye: a hidden canine tooth that had not yet erupted from the jaw bone. It was just what researchers needed to identify the fossil as belonging to a Homotherium, a genus of large cat that roamed much of the Earth for millions of years.
Published Novel virus identified in zebrafish from the pet trade causes disease in laboratory fish
(via sciencedaily.com) Original source Zebrafish in the pet trade are asymptomatic carriers of previously undescribed microbes, including a novel virus that causes hemorrhaging in infected laboratory fish, researchers report.
Published Origins of 'Welsh dragons' finally exposed by experts
(via sciencedaily.com) Original source A large fossil discovery has helped shed light on the history of dinosaurs in Wales.
Published Musankwa sanyatiensis, a new dinosaur from Zimbabwe
(via sciencedaily.com) Original source Fossils found on the shoreline of Lake Kariba in Zimbabwe represent a completely new dinosaur species. This remarkable find, named Musankwa sanyatiensis, marks only the fourth dinosaur species named from Zimbabwe.
Published Tracing the evolution of ferns' surprisingly sweet defense strategy
(via sciencedaily.com) Original source 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 strategy in ferns.
Published Antibiotic pollution disrupts the gut microbiome and blocks memory in aquatic snails
(via sciencedaily.com) Original source Antibiotics prevent snails from forming new memories by disrupting their gut microbiome -- the community of beneficial bacteria found in their guts.
Published Acute sense of touch helps hummingbirds hover near a flower without bumping into it
(via sciencedaily.com) Original source Hummingbird flight mechanics have been well studied but far less is known about how their sense of touch helps them sip nectar from a flower without bumping into it. Most of what scientists know about how touch is processed in the brain comes from studies on mammals, but bird brains are very different from mammal brains. New research shows that touch and air pressure on the wings and legs activate specific clusters of neurons in two regions of the forebrain to create a map of their body, which may help hummingbirds make nuanced adjustments to flight.
Published Researchers improve satellite surveillance of emperor penguins
(via sciencedaily.com) Original source New phenological and behavioral models will help scientists collect more accurate counts of emperor penguins. Emperor penguins are at the top of the food web. They are a reflection of how lower levels of the marine food web are being impacted by climate change. Systematic data collection on the biological component of ecosystems is still in its infancy, especially in harsh environments, in which consistent and repeatable research is particularly hard to achieve.
Published Slugs and snails love the city, unlike other animals
(via sciencedaily.com) Original source Most native species avoid more urbanized areas of Los Angeles, but slugs and snails may actually prefer these environments, according to a new study.
Published Bird flu: Diverse range of vaccines platforms 'crucial' for enhancing human pandemic preparedness
(via sciencedaily.com) Original source Review of research to-date suggests vaccination remains the most effective strategy for avian influenza prevention and control in humans, despite varying vaccine efficacy across strains.
Published Marine Protected Areas don't line up with core habitats of rare migratory fish, finds new research
(via sciencedaily.com) Original source 62% of Marine Protected Areas (MPAs) designated to protect rare migratory fish species are outside of their core habitats, according to a new modeling study.
Published Bringing back an ancient bird
(via sciencedaily.com) Original source Using ancient DNA extracted from the toe bone of a museum specimen, biologists have sequenced the genome of an extinct, flightless bird called the little bush moa, shedding light into an unknown corner of avian genetic history. The work is the first complete genetic map of the turkey-sized bird whose distant living cousins include the ostrich, emu, and kiwi.
Published Tracking animals without markers in the wild
(via sciencedaily.com) Original source Researchers developed a computer vision framework for posture estimation and identity tracking which they can use in indoor environments as well as in the wild. They have thus taken an important step towards markerless tracking of animals in the wild using computer vision and machine learning.
Published Global activity of seafloor biodiversity mapped
(via sciencedaily.com) Original source A team of scientists has used artificial intelligence (AI) to map the activities of seafloor invertebrate animals, such as worms, clams and shrimps, across all the oceans of the world.
Published Secrets of sargassum: Scientists advance knowledge of seaweed causing chaos in the Caribbean and West Africa
(via sciencedaily.com) Original source A research team tracked and studied floating sargassum in order to unlock its potential to be used to produce sustainable products.
Published On repeat: Biologists observe recurring evolutionary changes, over time, in stick insects
(via sciencedaily.com) Original source An evolutionary biologist reports evidence of repeatable evolution in populations of stick insects.
Published Entomologist sheds light on 250-year-old mystery of the German cockroach
(via sciencedaily.com) Original source Entomologists have solved the 250-year-old origin puzzle of the most prevalent indoor urban pest insect on the planet: the German cockroach. The team's research findings, representing the genomic analyses of over 280 specimens from 17 countries and six continents, show that this species evolved some 2,100 years ago from an outdoor-living species in Asia.
