Published 'Lost' birds list will aid in protecting species
(via sciencedaily.com) Original source A group of scientists has released the first comprehensive list of birds that haven't been documented with sound or video in more than a decade.
Published Research into structures of ape hearts provide insight into human evolution
(via sciencedaily.com) Original source Researchers have discovered new insights into the human heart's structure, revealing its evolutionary history. This study enhances understanding of heart development and its implications for treating heart disease.
Published Researchers use large language models to help robots navigate
(via sciencedaily.com) Original source A technique can plan a trajectory for a robot using only language-based inputs. While it can't outperform vision-based approaches, it could be useful in settings that lack visual data to use for training.
Published Early Homo sapiens facilitated the establishment of the Bonelli's eagle in the Mediterranean 50,000 years ago
(via sciencedaily.com) Original source Scientists have unraveled the ancestral history of one of the most iconic birds of prey in the current Iberian fauna: the Bonelli's eagle (Aquila fasciata). The study combines evidence from several disciplines, including palaeontology, genetics and ecology, to answer questions about when and why the Bonelli's eagle, a species primarily found in tropical and subtropical areas, colonized the Mediterranean Basin.
Published Self-assembling and disassembling swarm molecular robots via DNA molecular controller
(via sciencedaily.com) Original source Researchers have succeeded in developing a DNA-based molecular controller. Crucially, this controller enables the autonomous assembly and disassembly of molecular robots, as opposed to manually directing it.
Published Sharks have depleted functional diversity compared to the last 66 million years
(via sciencedaily.com) Original source New research has found that sharks retained high levels of functional diversity for most of the last 66 million years, before steadily declining over the last 10 million years to its lowest value in the present day.
Published A conservation market could incentivize global ocean protection
(via sciencedaily.com) Original source Thirty-by-thirty: protect 30% of the planet by 2030. While conservation is popular in principle, the costs of actually enacting it often stall even the most earnest efforts. Researchers have now proposed a market-based approach to achieving the 30x30 targets in the ocean.
Published Scientists unravel drivers of the global zinc cycle in our oceans, with implications for a changing climate
(via sciencedaily.com) Original source The understanding of the global zinc cycle in our oceans has important implications in the context of warming oceans. A warmer climate increases erosion, leading to more dust in the atmosphere and consequently more dust being deposited into the oceans. More dust means more scavenging of zinc particles, leading to less zinc being available to sustain phytoplankton and other marine life, thereby diminishing the oceans' ability to absorb carbon.
Published Paleontology: New fossil fish genus discovered
(via sciencedaily.com) Original source Paleontologists have identified a new genus of fossil goby, revealing evolutionary secrets of a lineage that stretches back millions of years.
Published New technique improves AI ability to map 3D space with 2D cameras
(via sciencedaily.com) Original source Researchers have developed a technique that allows artificial intelligence (AI) programs to better map three-dimensional spaces using two-dimensional images captured by multiple cameras. Because the technique works effectively with limited computational resources, it holds promise for improving the navigation of autonomous vehicles.
Published Marine heatwaves devastate red gorgonians in the Medes Islands
(via sciencedaily.com) Original source The increase in the frequency and intensity of marine heatwaves in recent decades is one of the effects of global climate change. A study shows that the extreme heatwave of 2022 caused an 'unprecedented' increase in mortality of the red gorgonian Paramuricea clavata, affecting 70% of the colonies located in the Montgr Natural Park, the Medes Islands and the Baix Ter. According to the researchers, these results are 'alarming and threaten the viability' of this species of great value for the biodiversity of benthic ecosystems, since it is considered to be an inhabitant-forming species.
Published Robot radiotherapy could improve treatments for eye disease
(via sciencedaily.com) Original source Researchers have successfully used a new robot system to improve treatment for debilitating eye disease.
Published Towards a new era in flexible piezoelectric sensors for both humans and robots
(via sciencedaily.com) Original source Flexible piezoelectric sensors are essential to monitor the motions of both humans and humanoid robots. However, existing designs are either are costly or have limited sensitivity. In a recent study, researchers tackled these issues by developing a novel piezoelectric composite material made from electrospun polyvinylidene fluoride nanofibers combined with dopamine. Sensors made from this material showed significant performance and stability improvements at a low cost, promising advancements in medicine, healthcare, and robotics.
Published Cocaine trafficking threatens critical bird habitats
(via sciencedaily.com) Original source In addition to its human consequences, cocaine trafficking harms the environment and threatens habitats important to dozens of species of migratory birds, according to a new study.
Published Humans are the elephant in the room where conservation is debated
(via sciencedaily.com) Original source Studies working to map conservation historically have left humans out of the equation. This study proposes ways to build in the outsized footprint created by people in wild places.
Published AI-powered simulation training improves human performance in robotic exoskeletons
(via sciencedaily.com) Original source Researchers have demonstrated a new method that leverages artificial intelligence (AI) and computer simulations to train robotic exoskeletons to autonomously help users save energy while walking, running and climbing stairs.
Published Female AI 'teammate' generates more participation from women
(via sciencedaily.com) Original source An artificial intelligence-powered virtual teammate with a female voice boosts participation and productivity among women on teams dominated by men, according to new research.
Published 3D-printed mini-actuators can move small soft robots, lock them into new shapes
(via sciencedaily.com) Original source Researchers have demonstrated miniature soft hydraulic actuators that can be used to control the deformation and motion of soft robots that are less than a millimeter thick. The researchers have also demonstrated that this technique works with shape memory materials, allowing users to repeatedly lock the soft robots into a desired shape and return to the original shape as needed.
Published Specialist and migratory birds at greater risk under climate change
(via sciencedaily.com) Original source Following decades of decline, even fewer birds will darken North American skies by the end of the century, according to a new analysis. The study examines the long-term effects of climate change on the abundance and diversity of bird groups across the continent as a whole while accounting for additional factors that put birds at risk.
Published Researchers harness AI for autonomous discovery and optimization of materials
(via sciencedaily.com) Original source Today, researchers are developing ways to accelerate discovery by combining automated experiments, artificial intelligence and high-performance computing. A novel tool that leverages those technologies has demonstrated that AI can influence materials synthesis and conduct associated experiments without human supervision.
