Published Bot inspired by baby turtles can swim under the sand
(via sciencedaily.com) This robot can swim under the sand and dig itself out too, thanks to two front limbs that mimic the oversized flippers of turtle hatchlings. It's the only robot that is able to travel in sand at a depth of 5 inches. It can also travel at a speed of 1.2 millimeters per second--roughly 4 meters, or 13 feet, per hour. This may seem slow but is comparable to other subterranean animals like worms and clams.
Published Robotics: New skin-like sensors fit almost everywhere
(via sciencedaily.com) Researchers have developed an automatic process for making soft sensors. These universal measurement cells can be attached to almost any kind of object. Applications are envisioned especially in robotics and prosthetics.
Published Building a better forest tree with CRISPR gene editing
(via sciencedaily.com) Original source Researchers use CRISPR techniques to modify lignin levels in poplar trees.
Published Robot team on lunar exploration tour
(via sciencedaily.com) Original source Engineers are training legged robots for future lunar missions that will search for minerals and raw materials. To ensure that the robots can continue to work even if one of them malfunctions, the researchers are teaching them teamwork.
Published Pump powers soft robots, makes cocktails
(via sciencedaily.com) Over the past several years, researchers have been developing soft analogues of traditionally rigid robotic components. In fluid-driven robotic systems, pumps control the pressure or flow of the liquid that powers the robot's movement. Most pumps available today for soft robotics are either too large and rigid to fit onboard, not powerful enough for actuation or only work with specific fluids. Researchers have now developed a compact, soft pump with adjustable pressure flow versatile enough to pump a variety of fluids with varying viscosity, including gin, juice, and coconut milk, and powerful enough to power soft haptic devices and a soft robotic finger.
Published Training robots how to learn, make decisions on the fly
(via sciencedaily.com) Original source Mars rovers have teams of human experts on Earth telling them what to do. But robots on lander missions to moons orbiting Saturn or Jupiter are too far away to receive timely commands from Earth. Researchers developed a novel learning-based method so robots on extraterrestrial bodies can make decisions on their own about where and how to scoop up terrain samples.
Published Revolutionary self-sensing electric artificial muscles
(via sciencedaily.com) Researchers have made groundbreaking advancements in bionics with the development of a new electric variable-stiffness artificial muscle. This innovative technology possesses self-sensing capabilities and has the potential to revolutionize soft robotics and medical applications. The artificial muscle seamlessly transitions between soft and hard states, while also sensing forces and deformations. With flexibility and stretchability similar to natural muscle, it can be integrated into intricate soft robotic systems and adapt to various shapes. By adjusting voltages, the muscle rapidly changes its stiffness and can monitor its own deformation through resistance changes. The fabrication process is simple and reliable, making it ideal for a range of applications, including aiding individuals with disabilities or patients in rehabilitation training.
Published Forest can adapt to climate change, but not quickly enough
(via sciencedaily.com) Original source America's forests have a tough time in store for them. Climate change is increasing temperatures and decreasing moisture levels across the country, not a winning combination for trees.
Published Study reveals how a tall spruce develops defense against hungry weevils
(via sciencedaily.com) Original source A study has identified genes involved in development of stone cells -- rigid cells that can block a nibbling insect from eating budding branches of the Sitka spruce evergreen tree. The insect's attack has stunted the growth of these forest giants.
Published GPT detectors can be biased against non-native English writers
(via sciencedaily.com) Original source Researchers show that computer programs commonly used to determine if a text was written by artificial intelligence tend to falsely label articles written by non-native language speakers as AI-generated. The researchers caution against the use of such AI text detectors for their unreliability, which could have negative impacts on individuals including students and those applying for jobs.
Published AI nursing ethics: Viability of robots and artificial intelligence in nursing practice
(via sciencedaily.com) Robots and artificial intelligence (AI) are expected to play a key role in nursing practice in the future. In this regard, researchers from Japan ask whether intelligent machines can replace humans as nurses. They investigate the potential of current advancements in robotics and AI to replicate the ethical concepts attributed to nurses, including advocacy, accountability, cooperation, and caring. While these technologies hold promise in enhancing healthcare practices, their integration into nursing requires careful consideration.
Published Bees make decisions better and faster than we do, for the things that matter to them
(via sciencedaily.com) Research reveals how millions of years of evolution has engineered honey bees to make fast decisions and reduce risk.
Published Biotechnology offers holistic approach to restoration of at-risk forest tree species
(via sciencedaily.com) Original source Many at-risk forest tree species will probably need biotechnology along with traditional tree-breeding approaches to survive, according to new insights.
Published An easier way to learn quantum processes
(via sciencedaily.com) Original source Scientists show that even a few simple examples are enough for a quantum machine-learning model, the 'quantum neural networks', to learn and predict the behavior of quantum systems, bringing us closer to a new era of quantum computing.
Published Robotic glove that 'feels' lends a 'hand' to relearn playing piano after a stroke
(via sciencedaily.com) Original source A new soft robotic glove is lending a 'hand' and providing hope to piano players who have suffered a disabling stroke or other neurotrauma. Combining flexible tactile sensors, soft actuators and AI, this robotic glove is the first to 'feel' the difference between correct and incorrect versions of the same song and to combine these features into a single hand exoskeleton. Unlike prior exoskeletons, this new technology provides precise force and guidance in recovering the fine finger movements required for piano playing and other complex tasks.
Published A seed survival story: How trees keep 'friends' close and 'enemies' guessing
(via sciencedaily.com) Original source A new study that included millions of tree-year observations worldwide for the first time documents and analyzes the intricate balance between seed defense and dispersal by forest trees at a global scale.
