Published The secret sex life of coral revealed
(via sciencedaily.com) Original source Corals play an essential role in ocean ecosystems, and like many organisms, they are under threat from climate change and other human activities. To better protect coral, it's first necessary to understand them, in particular their reproductive life cycle, which only happens once a year. For the first time, researchers have produced a model for coral spawning, based on various environmental factors. They achieved this by tapping an often overlooked source of aquatic knowledge, an aquarium.
Published Why do Dyeing poison frogs tap dance?
(via sciencedaily.com) Original source The toe tapping behavior of various amphibians has long attracted attention from researchers and pet owners. Despite being widely documented, the underlying functional role is poorly understood. In a new paper, researchers demonstrate that Dyeing poison frogs modulate their taps based on specific stimuli.
Published 'The magic of making electricity from metals and air' The vexing carbonate has achieved it!
(via sciencedaily.com) Original source Team develops a high-energy, high-efficiency all-solid-state Na-air battery platform.
Published How killifish embryos use suspended animation to survive over 8 months of drought
(via sciencedaily.com) Original source The African turquoise killifish lives in ephemeral ponds in Zimbabwe and Mozambique. To survive the annual dry season, the fish's embryos enter a state of extreme suspended animation or 'diapause' for approximately 8 months. Now, researchers have uncovered the mechanisms that enabled the killifish to evolve this extreme survival state.
Published Florida fossil porcupine solves a prickly dilemma 10-million years in the making
(via sciencedaily.com) Original source An exceptionally rare fossilized porcupine skeleton discovered in Florida has allowed researchers to trace the evolutionary history for one of North America's rarest mammals.
Published Echidnapus identified from an 'Age of Monotremes'
(via sciencedaily.com) Original source Australian researchers have found evidence of the oldest known platypus and a new species, dubbed 'echidnapus', which has a platypus-like anatomy alongside features that more closely resemble an echidna.
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.
Published Caterpillars can detect their predators by the static electricity they emit
(via sciencedaily.com) Original source Caterpillars respond defensively to electric fields similar to those emitted by their natural predators, scientists have found.
Published Renewable grid: Recovering electricity from heat storage hits 44% efficiency
(via sciencedaily.com) Original source Closing in on the theoretical maximum efficiency, devices for turning heat into electricity are edging closer to being practical for use on the grid, according to new research.
Published Key role of plant-bacteria communication for the assembly of a healthy plant microbiome supporting sustainable plant nutrition
(via sciencedaily.com) Original source In an interdisciplinary study, researchers discovered that symbiotic bacteria communicate with legume plants through specific molecules and that this communication influences which bacteria grow near the plant roots. The findings provide insights into how plants and soil bacteria form beneficial partnerships for nutrient uptake and resilience. These results are a step towards understanding how communication between plants and soil bacteria can lead to specific beneficial associations providing plants with nutrients.
Published Psychedelic drug-induced hyperconnectivity in the brain helps clarify altered subjective experiences
(via sciencedaily.com) Original source A new study shows that the use of psilocybin, a compound found in the widely known 'magic mushrooms,' initiates a pattern of hyperconnectivity in the brain linked to the ego-modifying effects and feelings of oceanic boundlessness. The findings help explain the so-called mystical experiences people report during the use of psychedelics and are pertinent to the psychotherapeutic applications of psychedelic drugs to treat psychiatric disorders such as depression.
Published Iron could be key to less expensive, greener lithium-ion batteries, research finds
(via sciencedaily.com) Original source Chemistry researchers are hoping to spark a green battery revolution by showing that iron instead of cobalt and nickel can be used as a cathode material in lithium-ion batteries.
Published New milestone for lithium metal batteries
(via sciencedaily.com) Original source Scientists develop a porous structures for lithium metal batteries.
Published Bigger is better: Male proboscis monkeys' enhanced noses evolved to attract mates
(via sciencedaily.com) Original source When it comes to the animal kingdom, bigger is better. Well, at least for proboscis monkeys, famously known for their long, large and droopy noses. Researchers have provided a world-first explanation for why male proboscis monkeys have larger and 'enhanced' nasal structures.
Published Foraging ants navigate more efficiently when given energy-drink-like doses of caffeine
(via sciencedaily.com) Original source Ants who receive a caffeine-laced sugary reward become more efficient at navigating back to the reward's location compared to ants that only receive sugar. Caffeinated ants move toward the reward via a more direct path but do not increase their speed, suggesting that caffeine improved their ability to learn. The study was conducted on Argentine ants (Linepithema humile), a globally invasive species, and the researchers say that incorporating caffeine into ant baits could aid efforts to control the ants by improving bait uptake.
Published Sexual parasitism helped anglerfish invade the deep sea during a time of global warming
(via sciencedaily.com) Original source Members of the vertebrate group including anglerfishes are unique in possessing a characteristic known as sexual parasitism, in which males temporarily attach or permanently fuse with females to mate. Now, researchers show that sexual parasitism arose during a time of major global warming and rapid transition for anglerfishes from the ocean floor to the deep, open sea.
Published Australian study proves 'humans are planet's most frightening predator'
(via sciencedaily.com) Original source A new study demonstrates that kangaroos, wallabies and other Australian marsupials fear humans far more than any other predator.
Published New AI accurately predicts fly behavior
(via sciencedaily.com) Original source Researchers trained an AI model to accurately predict male fruit flies' courtship behavior in response to any sight of a female. This breakthrough offers new insight into how the brain processes visual data and may someday pave the way for artificial vision technology.
Published Cuddled cows who work as therapy animals showed a strong preference for women compared to men, study finds
(via sciencedaily.com) Original source A new study reveals that cows who are cuddled as therapy animals showed a strong preference for interactions with women when compared to men. In turn, the research, which opens a new era on whether some therapies may be initially stronger based upon gender and not procedure, highlighted that the women also reported greater attachment behaviors towards the steers.
Published Study finds widespread 'cell cannibalism,' related phenomena across tree of life
(via sciencedaily.com) Original source Researchers describe cell-in-cell phenomena in which one cell engulfs and sometimes consumes another. The study shows that cases of this behavior, including cell cannibalism, are widespread across the tree of life. The findings challenge the common perception that cell-in-cell events are largely restricted to cancer cells. Rather, these events appear to be common across diverse organisms, from single-celled amoebas to complex multicellular animals.
