Published Deep-sea mining and warming trigger stress in a midwater jellies
(via sciencedaily.com) Original source The deep sea is home to one of the largest animal communities on earth which is increasingly exposed to environmental pressures. However, our knowledge of its inhabitants and their response to human-induced stressors is still limited. A new study now provides first insights into the stress response of a pelagic deep-sea jellyfish to ocean warming and sediment plumes caused by deep-sea mining.
Published Long in the Bluetooth: Scientists develop a more efficient way to transmit data between our devices
(via sciencedaily.com) Original source Researchers have developed a more energy efficient way of connecting our personal devices. New technology consumes less power than Bluetooth and can improve battery life of tech accessories, including earbuds and fitness trackers. Future applications could see us unlocking a door by touching its handle or shaking hands to exchange phone numbers.
Published Innovative aquaculture system turns waste wood into nutritious seafood
(via sciencedaily.com) Original source Innovative aquaculture system turns waste wood into nutritious seafood. Researchers hoping to rebrand a marine pest as a nutritious food have developed the world's first system of farming shipworms, which they have renamed 'Naked Clams'.
Published Microbiome development: Bacteria lay the foundations for their descendants
(via sciencedaily.com) Original source The microbiome (the symbiotic community of microbial organisms of a host) is of existential importance for the functioning of every plant and animal, including human beings. A research team has now used the example of the sea anemone Nematostella vectenis to investigate how the microbiome develops together with the host. The researchers describe that the bacterial community is primarily controlled by the host organism during the early stages of life, while bacteria-bacteria interactions play the lead role in subsequent development.
Published Researchers develop comprehensive genetic map for bison, discover gene responsible for albinism
(via sciencedaily.com) Original source Researchers have determined the gene mutation responsible for an observable trait in bison -- albinism.
Published Idai vs. Impalas: New study shows in real-time what helps mammals survive a natural disaster
(via sciencedaily.com) Original source After a massive cyclone transformed the ecosystem of Gorongosa National Park, researchers studied the immediate and knock-on impacts to garner lessons for wildlife managers around the world.
Published A deep-sea fish inspired researchers to develop supramolecular light-driven machinery
(via sciencedaily.com) Original source Chemists have developed a bioinspired supramolecular approach to convert photo-switchable molecules from their stable state into metastable one with low-energy red light. Their work enables fast, highly selective, and efficient switching, providing new tools for energy storage, activation of drugs with light, and sensing applications.
Published Scientists have solved the damselfly color mystery
(via sciencedaily.com) Original source For over 20 years, a research team has studied the common bluetail damselfly. Females occur in three different color forms -- one with a male-like appearance, something that protects them from mating harassment. In a new study, an international research team found that this genetic color variation that is shared between several species arose through changes in a specific genomic region at least five million years ago.
Published Like the phoenix, Australia's giant birds of prey rise again from limestone caves
(via sciencedaily.com) Original source Australia's only vulture, and a fearsome extinct eagle, are among the earliest recorded birds of prey from the Pleistocene period more than 50,000 years ago -- and now researchers are bringing them to 'life' again. Along with new scientific information, a bold new pictorial reconstruction of a newly named eagle and the only known Australian vulture will be unveiled at the World Heritage-listed Naracoorte Caves in South Australia's Limestone Coast this month.
Published Nature photographers posting to social media help with protecting biodiversity
(via sciencedaily.com) Original source Nature photographers posting to social media are helping improve biodiversity conservation mapping in South Asia, and the method could go global.
Published Novel measurement technique for fluid mixing phenomena using selective color imaging method
(via sciencedaily.com) Original source A novel measurement technique has been developed to visualize the fluid flow and distribution within two droplets levitated and coalesced in space using fluorescence-emitting particles. This technique enabled the estimation of fluid motion within each droplet, thereby revealing the internal flow caused by surface vibration when the droplet merging promotes fluid mixing.
Published Temperature variability reduces nesting success
(via sciencedaily.com) Original source Many songbirds are nesting earlier in spring because of warmer temperatures brought about by climate change. But the shift brings another danger that is especially deadly for nestlings: greater exposure to temperature variability in the form of cold snaps and heat waves.
Published Birds set foot near South Pole in Early Cretaceous, Australian tracks show
(via sciencedaily.com) Original source The discovery of 27 avian footprints on the southern Australia coast -- dating back to the Early Cretaceous when Australia was still connected to Antarctica -- opens another window onto early avian evolution and possible migratory behavior.
Published Forget social distancing: House finches become more social when sick
(via sciencedaily.com) Original source Social distancing when sick has become second nature to many of us in the past few years, but some sick animals appear to take a different approach. A new study of house finches uncovered a surprising result. Unlike other social animals who passively or actively isolate themselves when sick, this gregarious backyard bird species gravitates toward healthy flock mates when they are sick, even more so than healthy birds do.
Published Researchers discover way to boost shelter dog adoptions
(via sciencedaily.com) Original source Researchers are working to help more shelter dogs experience this kind of love, safety, and happiness in an adoptive home. The research team found that implementing shorter-term fostering programs at animal shelters vastly improves adoptions for our canine friends.
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 New laser setup probes metamaterial structures with ultrafast pulses
(via sciencedaily.com) Original source A new technique offers a safe, reliable, and high-throughput way to dynamically characterize microscale metamaterials. The method could speed up the development of acoustic lenses, impact-resistant films, and other futuristic materials.
Published Roaming seabirds need ocean-wide protection
(via sciencedaily.com) Original source Seabirds roam far and wide in the Indian Ocean -- so they need ocean-wide protection, new research shows.
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 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.
