Published Interactive cyber-physical human: Generating contact-rich whole-body motions
(via sciencedaily.com) Performing human-like motions that involve multiple contacts is challenging for robots. In this regard, a researcher has envisioned an interactive cyber-physical human (iCPH) platform with complementary humanoid (physical twin) and simulation (digital twin) elements. iCPH combines human measurement data, musculoskeletal analysis, and machine learning for data collection and augmentation. As a result, iCPH can understand, predict, and synthesize whole-body contact motions.
Published Robot: I'm sorry. Human: I don't care anymore!
(via sciencedaily.com) Humans are less forgiving of robots after multiple mistakes -- and the trust is difficult to get back, according to a new study.
Published Contributing to the utilization of big data! Developing new data learning methods for artificial intelligence
(via sciencedaily.com) A research group has developed a new learning method for artificial intelligence that combines classification performance for data with multiple labels with the ability to learn continually from data. Numerical experiments on real-world multi-label data indicate that the new method outperforms conventional approaches. The simplicity of this algorithm makes it easy to integrate it with other algorithms to devise new ones.
Published Deer browsing is just one of many factors shaping North American forests
(via sciencedaily.com) In a new study, a research team discovered evidence that browsing by white-tailed deer had relatively little long-term impact on two tree species in a northern forest.
Published Legged robots need more testing before real-world use
(via sciencedaily.com) When it comes to the 'evolution' of mobile robots, it may be a long time before legged robots are able to safely interact in the real world, according to a new study.
Published Autonomous steering system keeps human drivers engaged
(via sciencedaily.com) Researchers have developed an automated driving system based on the concept of 'collaborative steering', which aims to increase transportation safety, efficiency, and comfort by encouraging active interaction between autonomous vehicles and their human drivers.
Published UK's Overseas Territories at ongoing risk from wide range of invasive species
(via sciencedaily.com) A new study has for the first time predicted which invasive species could pose a future threat to the UK's ecologically unique Overseas Territories.
Published A fairy-like robot flies by the power of wind and light
(via sciencedaily.com) The loss of pollinators, such as bees, is a huge challenge for global biodiversity and affects humanity by causing problems in food production. Researchers have now developed the first passively flying robot equipped with artificial muscle. Could this artificial fairy be utilized in pollination?
Published New species of microalgae discovered
(via sciencedaily.com) A new species of microalgae was found in water from a home aquarium. While analyzing DNA samples taken from the algae, researchers discovered Medakamo hakoo, whose DNA sequence didn't match any on record. This new species is the smallest known freshwater green algae, with inherent qualities which enable it to be cultured stably at high density, meaning it could be effectively used to produce useful products for food and industry.
Published Ancestral variation guides future environmental adaptations
(via sciencedaily.com) The speed of environmental change is very challenging for wild organisms. When exposed to a new environment individual plants and animals can potentially adjust their biology to better cope with new pressures they are exposed to -- this is known as phenotypic plasticity. New research shows that early plasticity can influence the ability to subsequently evolve genetic adaptations to conquer new habitats.
Published Rapid plant evolution may make coastal regions more susceptible to flooding and sea level rise, study shows
(via sciencedaily.com) Evolution has occurred more rapidly than previously thought in the Chesapeake Bay wetlands, which may decrease the chance that coastal marshes can withstand future sea level rise, researchers at the University of Notre Dame and collaborators demonstrated in a recent publication in Science.
Published Artificial human skin paves the way to new skin cancer therapy
(via sciencedaily.com) In a new study, researchers have managed to curb skin cancer. The study was conducted on artificial human skin.
Published How salmon feed flowers and flourishing ecosystems
(via sciencedaily.com) Nutrients from salmon carcasses can substantively alter the growth and reproduction of plant species in the surrounding habitat, and even cause some flowers to grow bigger and more plentiful, researchers have found.
Published Versatile robo-dog runs through the sandy beach at 3 meters per second
(via sciencedaily.com) Meet the new addition to the robo-dog family, 'RaiBo', that can run along the sandy beach without losing balance and walk through grassy fields and back on the hard-floored tracking fields all on its own -- no further tinkering necessary.
Published Person-shaped robot can liquify and escape jail, all with the power of magnets
(via sciencedaily.com) Inspired by sea cucumbers, engineers have designed miniature robots that rapidly and reversibly shift between liquid and solid states. On top of being able to shape-shift, the robots are magnetic and can conduct electricity. The researchers put the robots through an obstacle course of mobility and shape-morphing tests.
Published Artificial photosynthesis uses sunlight to make biodegradable plastic
(via sciencedaily.com) Scientists have succeeded in synthesizing fumaric acid, a raw material for plastics, from CO2 powered by solar energy. Typically, fumaric acid is synthesized from petroleum as a raw material to make polybutylene succinate, a biodegradable plastic, but this research shows that it can be synthesized from CO2 and biomass-derived compounds using renewable energy.
Published Fish sensory organ key to improving navigational skills of underwater robots
(via sciencedaily.com) Scientists have been studying a fish sensory organ to understand cues for collective behavior which could be employed on underwater robots.
Published Economics trump environment to save big cats, say ecologists
(via sciencedaily.com) Rapid economic growth has pushed rare species of big carnivores to the brink of extinction, but ecologists have suggested our appetite to once again live alongside big cats is increasing.
Published Immense diversity and interdependence in high temp deep-sea microorganism communities
(via sciencedaily.com) A new study finds that microorganisms live in richly diverse and interdependent communities in high-temperature geothermal environments in the deep sea. By constructing genomes of 3,635 Bacteria and Archaea from 40 different rock communities, researchers discovered at least 500 new genera and have evidence for two new phyla. Samples from the deep-sea Brothers volcano were especially enriched with different kinds of microorganisms, many endemic to the volcano. The genomic data from this study also showed that many of these organisms depend on one another for survival. Some microorganisms cannot metabolize all of the nutrients they need to survive so they rely on nutrients created by other species in a process known as a 'metabolic handoff.'
Published Click beetle-inspired robots jump using elastic energy
(via sciencedaily.com) Researchers have made a significant leap forward in developing insect-sized jumping robots capable of performing tasks in the small spaces often found in mechanical, agricultural and search-and-rescue settings. A new study demonstrates a series of click beetle-sized robots small enough to fit into tight spaces, powerful enough to maneuver over obstacles and fast enough to match an insect's rapid escape time.
