Published A key to the future of robots could be hiding in liquid crystals



Robots and cameras of the future could be made of liquid crystals, thanks to a new discovery that significantly expands the potential of the chemicals already common in computer displays and digital watches. The findings are a simple and inexpensive way to manipulate the molecular properties of liquid crystals with light exposure.
Published New dressing robot can 'mimic' the actions of care-workers



Scientists have developed a new robot that can 'mimic' the two-handed movements of care-workers as they dress an individual.
Published A model for the evolution of intelligence



When certain species of wild birds and primates discover new ways of finding food in the wild, it can serve to measure their flexibility and intelligence. In the largest experimental study ever conducted on this topic, researchers have shown that foraging problems requiring overcoming obstacles, such as removing the lid off a container of food, are the only predictors of brain size and innovative behavior in the wild.
Published Study results show 25% of pregnant people are not getting enough omega-3 fatty acids from their diet or dietary supplements



Results from a new US nationwide cohort study show that, despite strong recommendations in favor of consuming omega-3 fatty acids for optimal pregnancy outcomes and offspring health, 25% of participants reported rarely, or never eating fish during pregnancy, with fewer taking omega-3 supplements.
Published AI outperforms humans in standardized tests of creative potential



In a recent study, 151 human participants were pitted against ChatGPT-4 in three tests designed to measure divergent thinking, which is considered to be an indicator of creative thought.
Published AI-enabled atomic robotic probe to advance quantum material manufacturing



Scientists have pioneered a new methodology of fabricating carbon-based quantum materials at the atomic scale by integrating scanning probe microscopy techniques and deep neural networks. This breakthrough highlights the potential of implementing artificial intelligence at the sub-angstrom scale for enhanced control over atomic manufacturing, benefiting both fundamental research and future applications.
Published Shining a light on the effects of habituation and neural adaptation on the evolution of animal signals



A new paper examines the possible effects of two properties of receiver playing fields documented in studies of animal psychology -- habituation and neural adaptation -- on the efficacy of mate choice signals.
Published Scientists discover 18 new species of gut microbes in search for origins of antibiotic resistance



Researchers have discovered 18 new species of Enterococcus type bacteria from soil samples collected from all corners of the globe, which may offer new clues to the origins of antibiotic-resistant infections in hospitals.
Published Building bionic jellyfish for ocean exploration



Researchers show how biohybrid robots based on jellyfish could be used to gather climate science data from deep in the Earth's oceans.
Published Slimming down a colossal fossil whale



A 30 million year-old fossil whale may not be the heaviest animal of all time after all, according to a new analysis by paleontologists. The new analysis puts Perucetus colossus back in the same weight range as modern whales and smaller than the largest blue whales ever recorded.
Published Small dietary changes can cut your carbon footprint by 25%



New research provides compelling evidence that partially substituting animal with plant protein foods can increase life expectancy and decrease greenhouse gas emissions. Importantly, it also suggests that benefits depend on the type of animal protein being replaced. The study drew data from a national nutrition survey to analyze Canadians' dietary records. The study modeled partial replacements (25% and 50%) of either red and processed meat or dairy with plant protein foods like nuts, seeds, legumes, tofu, and fortified soy beverages, on a combination of nutrition, health, and climate outcomes.
Published Uncertainty in measuring biodiversity change could hinder progress towards global targets for nature



More than ever before, there is a growing interest in dedicating resources to stop the loss of biodiversity, as recently exemplified by the Kunming-Montreal Global Biodiversity Framework (GBF) decided at COP15 in December 2022. The GBF focuses on understanding why biodiversity is declining and what actions are needed to reverse this trend. However, according to researchers, implementing the plan is challenging because information about biodiversity changes is not evenly available everywhere, and is uncertain in many places.
Published The Golgi organelle's ribbon structure is not exclusive to vertebrates, contrary to previous consensus



Researchers report that the Golgi ribbon, an organelle structure previously thought to be exclusive to vertebrates, is also present in animal taxa, including mollusks, earthworms, and sea urchins. The function of the Golgi ribbon is still enigmatic, but its presence in diverse animal lineages indicates that its function is not vertebrate specific, as previously thought. The team also showed Golgi ribbons form at a specific timepoint during embryogenesis, which suggests that they might play a role in cell differentiation.
Published The veil varies more than the threat: Predator selection on variability in camouflage and warning signals



Researchers leveraged open-access digital collections to validate an age-old hypothesis in evolutionary ecology. The classic hypothesis proposes that predators select for a great variety of camouflage and a limited variety of warning signals, but the idea has never been tested on natural prey.
Published Older African elephants will be most severely affected by the changing climate



Older elephants in East Africa will be most severely impacted by climate change, threatening the long-term survival of this vulnerable African mammal, according to a new study.
Published Avian influenza virus is adapting to spread to marine mammals



Avian influenza virus H5N1 has adapted to spread between birds and marine mammals, finds a new study.
Published New AI model could streamline operations in a robotic warehouse



Researchers applied deep-learning approaches from vehicle routing to streamline planning trajectories for robots in an e-commerce warehouse. Their method breaks the problem down into smaller chunks and then predicts the best chunks to solve with traditional algorithms.
Published Climate change shrinking fish



Fish weight in the western North Pacific Ocean dipped in the 2010s due to warmer water limiting food supplies, according to a new study. Researchers analyzed the individual weight and overall biomass of 13 species of fish. In the 1980s and 2010s, the fish were lighter. They attributed the first period of weight loss to greater numbers of Japanese sardine, which increased competition with other species for food. During the 2010s, while the number of Japanese sardine and chub mackerel moderately increased, the effect of climate change warming the ocean appears to have resulted in more competition for food, as cooler, nutrient-dense water could not easily rise to the surface. These results have implications for fisheries and policymakers trying to manage ocean resources under future climate change scenarios.
Published First metamaterial developed to enable real-time shape and property control



Engineers have unveiled an encodable multifunctional material that can dynamically tune its shape and mechanical properties in real time.
Published Researchers are first to see at-risk bat flying over open ocean



On a research cruise focused on marine mammals and seabirds, scientists earned an unexpected bonus: The first-ever documented sighting of a hoary bat flying over the open ocean.
