Published Who are the first ancestors of present-day fish?
(via sciencedaily.com) What is the origin of the ancestors of present-day fish? What species evolved from them? A 50-year-old scientific controversy revolved around the question of which group, the 'bony-tongues' or the 'eels', was the oldest. A study has just put an end to the debate by showing through genomic analysis that these fishes are in fact one and the same group, given the rather peculiar name of 'Eloposteoglossocephala'. These results shed new light on the evolutionary history of fish.
Published Tiny new climbing robot was inspired by geckos and inchworms
(via sciencedaily.com) A tiny robot that could one day help doctors perform surgery was inspired by the incredible gripping ability of geckos and the efficient locomotion of inchworms.
Published Reaching like an octopus: A biology-inspired model opens the door to soft robot control
(via sciencedaily.com) Octopus arms coordinate nearly infinite degrees of freedom to perform complex movements such as reaching, grasping, fetching, crawling, and swimming. How these animals achieve such a wide range of activities remains a source of mystery, amazement, and inspiration. Part of the challenge comes from the intricate organization and biomechanics of the internal muscles.
Published This new sensor can detect mercury ions with just a tap
(via sciencedaily.com) Although many measures are in place to prevent contamination, pollutants, such as mercury and lead, can still end up in the environment. Sensing them often requires complicated processes, but what if you could detect them with the tap of a fingertip? Researchers have now developed a self-powered nanosensor that can discover small amounts of mercury ions and immediately report the result.
Published Robot helps students with learning disabilities stay focused
(via sciencedaily.com) Engineering researchers are successfully using a robot to help keep children with learning disabilities focused on their work.
Published Researchers develop new, automated, powerful diagnostic tool for drug detection
(via sciencedaily.com) Biomedical engineers present a robust new method for accurately measuring and identifying eight antidepressants most commonly prescribed to women.
Published Compact, non-mechanical 3D lidar system could make autonomous driving safer
(via sciencedaily.com) A new system represents the first time that the capabilities of conventional beam-scanning lidar systems have been combined with those of a newer 3D approach known as flash lidar. The nonmechanical 3D lidar system is compact enough to fit in the palm of the hand and solves issues of detecting and tracking poorly reflective objects.
Published Bite this! Mosquito feeding chamber uses fake skin, real blood
(via sciencedaily.com) Bioengineers and experts in tropical medicine have invented a new way of studying mosquito feeding behavior using technology instead of live volunteers. Their open-source design combines automated cameras, artificial intelligence and blood-infused, 3D-printed 'synthetic skin.'
Published Engineers devise a modular system to produce efficient, scalable aquabots
(via sciencedaily.com) Researchers developed a new approach to building deformable underwater robots, using simple repeating substructures. The team demonstrated the new system in two different example configurations, one like an eel and the other a wing-like hydrofoil.
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 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 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 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 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.
