Published Phytoplankton blooms offer insight into impacts of climate change
(via sciencedaily.com) The first study into the biological response of the upper ocean in the wake of South Pacific cyclones could help predict the impact of warming ocean temperatures, researchers believe.
Published Robot caterpillar demonstrates new approach to locomotion for soft robotics
(via sciencedaily.com) Researchers have demonstrated a caterpillar-like soft robot that can move forward, backward and dip under narrow spaces. The caterpillar-bot's movement is driven by a novel pattern of silver nanowires that use heat to control the way the robot bends, allowing users to steer the robot in either direction.
Published Biodegradable artificial muscles: Going green in the field of soft robotics
(via sciencedaily.com) Scientists have developed fully biodegradable, high-performance artificial muscles. Their research project marks another step towards green technology becoming a lasting trend in the field of soft robotics.
Published Photosynthesis 'hack' could lead to new ways of generating renewable energy
(via sciencedaily.com) Researchers have 'hacked' the earliest stages of photosynthesis, the natural machine that powers the vast majority of life on Earth, and discovered new ways to extract energy from the process, a finding that could lead to new ways of generating clean fuel and renewable energy.
Published Simulated terrible drivers cut the time and cost of AV testing by a factor of one thousand
(via sciencedaily.com) The push toward truly autonomous vehicles has been hindered by the cost and time associated with safety testing, but a new system shows that artificial intelligence can reduce the testing miles required by 99.99%.
Published Forest growing season in eastern U.S. has increased by a month
(via sciencedaily.com) The growing period of hardwood forests in eastern North America has increased by an average of one month over the past century as temperatures have steadily risen, a new study has found.
Published Douglas-fir in Klamath Mountains are in 'decline spiral'
(via sciencedaily.com) Increases in mortality among Douglas-fir in the Klamath Mountains are the result of multiple factors that have the iconic tree in a 'decline spiral' in parts of the region.
Published Head-worn device can control mobile manipulators
(via sciencedaily.com) New research aims to increase autonomy for individuals with such motor impairments by introducing a head-worn device that will help them control a mobile manipulator. Teleoperated mobile manipulators can aid individuals in completing daily activities, but many existing technologies like hand-operated joysticks or web interfaces require a user to have substantial fine motor skills to effectively control them. Research led by robotics Ph.D. student Akhil Padmanabha offers a new device equipped with a hands-free microphone and head-worn sensor that allows users to control a mobile robot via head motion and speech recognition.
Published Genome research: Origin and evolution of vine
(via sciencedaily.com) Cultivation and growth of grapevines have strongly influenced European civilizations, but where the grapevine comes from and how it has spread across the globe has been highly disputed so far. In an extensive genome project, researchers have determined its origin and evolution from the wild vine to today's cultivar by analyzing thousands of vine genomes collected along the Silk Road from China to Western Europe.
Published Mind-control robots a reality?
(via sciencedaily.com) Researchers have developed biosensor technology that will allow you to operate devices, such as robots and machines, solely through thought control.
Published A sowing, pruning, and harvesting robot for SynecocultureTM farming
(via sciencedaily.com) Synecoculture, a new farming method, involves growing mixed plant species together in high density. However, it requires complex operation since varying species with different growing seasons and growing speeds are planted on the same land. To address this need, researchers have developed a robot that can sow, prune, and harvest plants in dense vegetation growth. Its small, flexible body will help large-scale Synecoculture. This is an important step towards achieving sustainable farming and carbon neutrality.
Published 3D-printed revolving devices can sense how they are moving
(via sciencedaily.com) Researchers created a system that enables makers to incorporate sensors directly into rotational mechanisms with only one pass in a 3D printer. This gives rotational mechanisms like gearboxes the ability to sense their angular position, rotation speed, and direction of rotation.
Published An elegant new orchid hiding in plain sight
(via sciencedaily.com) It is extremely rare for a new plant species to be discovered in Japan, a nation where flora has been extensively studied and documented. Nevertheless, botanists recently uncovered a stunning new species of orchid whose rosy pink petals bear a striking resemblance to glasswork. Interestingly, it can be found in familiar environments such as lawns and parks, and even in private gardens and on balconies. This research suggests that other new species may be hiding in common places.
Published How can we tackle the biggest challenges? Ask a plant
(via sciencedaily.com) Without plants, we'd have no air to breathe or food to eat, yet plant science lingers in the shadowy wings while other fields take center stage. With the goal of shining the spotlight on plants, a new study presents the field's top 100 most pressing questions for research to address the greatest challenges facing humanity.
Published Electronic skin as flexible as crocodile skin
(via sciencedaily.com) A research team has developed a crocodile-skin-inspired omnidirectionally stretchable pressure sensor.
Published Compressive stress shapes the symmetry of Arabidopsis root vascular tissue
(via sciencedaily.com) A cytokinin-mediated, proliferation-based mechanism is involved in the generation and maintenance of cell-type specific tissue boundaries during vascular development in Arabidopsis roots. Specifically, the HANABA-TARANU transcription factor forms a feed-forward loop to cytokinin signaling, which in turn regulates the position and frequency of cell proliferation of proto-vascular cells such that mechanical stress of the surrounding tissues guides growth in an apical-oriented manor, maintaining cell patterning throughout the tissue section.
Published Bigger flowers, greater rewards: Plants adapt to climate disruptions to lure pollinators
(via sciencedaily.com) There's been a well-documented shift toward earlier springtime flowering in many plants as the world warms. The trend alarms biologists because it has the potential to disrupt carefully choreographed interactions between plants and the creatures -- butterflies, bees, birds, bats and others -- that pollinate them.
Published Resilient bug-sized robots keep flying even after wing damage
(via sciencedaily.com) Researchers have developed resilient artificial muscles that can enable insect-scale aerial robots to effectively recover flight performance after suffering severe damage.
Published Researchers control the degree of twist in nanostructured particles
(via sciencedaily.com) Micron-sized 'bow ties,' self-assembled from nanoparticles, form a variety of different curling shapes that can be precisely controlled, a research team has shown.
Published Mix-and-match kit could enable astronauts to build a menagerie of lunar exploration bots
(via sciencedaily.com) The Walking Oligomeric Robotic Mobility System, or WORMS, is a reconfigurable, modular, multiagent robotics architecture for extreme lunar terrain mobility. The system could be used to assemble autonomous worm-like parts into larger biomimetic robots that could explore lava tubes, steep slopes, and the moon's permanently shadowed regions.
