Published Public have no difficulty getting to grips with an extra thumb, study finds
(via sciencedaily.com) Original source Researchers have shown that members of the public have little trouble in learning very quickly how to use a third thumb -- a controllable, prosthetic extra thumb -- to pick up and manipulate objects. The team tested the robotic device on a diverse range of participants, which they say is essential for ensuring new technologies are inclusive and can work for everyone.
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 What are the risks of hydrogen vehicles in tunnels?
(via sciencedaily.com) Original source A team has analyzed the risk and damage potential of hydrogen vehicles in tunnels and derived recommendations. Their conclusion? Any damage would be extensive, but its occurrence is unlikely.
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 Close to 1 in 2 surveyed say they would use air taxis in the future
(via sciencedaily.com) Original source Through a study of 1,002 participants, scientists have found that almost half (45.7 per cent) say they intend to use air taxis when they become available, with over one-third (36.2 per cent) planning to do so regularly. According to the findings, the intention to take autonomous air taxis is associated with factors such as trust in the AI technology deployed in air taxis, hedonic motivation (the fun or pleasure derived from using technology), performance expectancy (the degree to which users expect that using the system will benefit them), and news media attention (the amount of attention paid to news about air taxis).
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 AI headphones let wearer listen to a single person in a crowd, by looking at them just once
(via sciencedaily.com) Original source Engineers have developed an artificial intelligence system that lets someone wearing headphones look at a person speaking for three to five seconds to 'enroll' them. The system then plays just the enrolled speaker's voice in real time, even as the pair move around in noisy environments.
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 Imperceptible sensors made from 'electronic spider silk' can be printed directly on human skin
(via sciencedaily.com) Original source Researchers have developed a method to make adaptive and eco-friendly sensors that can be directly and imperceptibly printed onto a wide range of biological surfaces, whether that's a finger or a flower petal.
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 Birth of universe's earliest galaxies observed for first time
(via sciencedaily.com) Original source Researchers have now seen the formation of three of the earliest galaxies in the universe, more than 13 billion years ago. The sensational discovery contributes important knowledge about the universe.
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 Intriguing nearby world sized between Earth, Venus
(via sciencedaily.com) Original source Astronomers have discovered a planet between the sizes of Earth and Venus only 40 light-years away.
Published Planet hunters unveil massive catalog of strange worlds
(via sciencedaily.com) Original source While thousands of planets have been discovered around other stars, relatively little is known about them. A NASA catalog featuring 126 exotic, newly discovered worlds includes detailed measurements that allow for comparisons with our own solar system.
Published First pictures from Euclid satellite reveal billions of orphan stars
(via sciencedaily.com) Original source The first scientific pictures from the Euclid satellite mission have revealed more than 1,500 billion orphan stars scattered throughout the Perseus cluster of galaxies.
Published Potentially habitable 'exo-Venus' with Earth-like temperature discovered
(via sciencedaily.com) Original source Astronomers have made the rare and tantalizing discovery of an Earth-like exoplanet 40 light-years away that may be just a little warmer than our own world. The potentially-habitable planet, named Gliese 12 b, orbits its host star every 12.8 days, is comparable in size to Venus -- so slightly smaller than Earth -- and has an estimated surface temperature of 42 C (107 F), which is lower than most of the 5,000-odd exoplanets confirmed so far. That is assuming it has no atmosphere, however, which is the crucial next step to establishing if it is habitable.
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.
