Published Preschoolers prefer to learn from a competent robot than an incompetent human
(via sciencedaily.com) Researchers found that preschoolers prefer learning from what they perceive as a competent robot over an incompetent human. This study is the first to use both a human speaker and a robot to see if children deem social affiliation and similarity more important than competency when choosing which source to trust and learn from.
Published Meet the hybrid micro-robot: The tiny robot that is able to navigate in a physiological environment and capture targeted damaged cells
(via sciencedaily.com) Researchers have developed a hybrid micro-robot, the size of a single biological cell (about 10 microns across), that can be controlled and navigated using two different mechanisms -- electric and magnetic. The micro-robot is able to navigate between different cells in a biological sample, distinguish between different types of cells, identify whether they are healthy or dying, and then transport the desired cell for further study, such as genetic analysis.
Published Artificial intelligence discovers secret equation for 'weighing' galaxy clusters
(via sciencedaily.com) Astrophysicists have leveraged artificial intelligence to uncover a better way to estimate the mass of colossal clusters of galaxies. The AI discovered that by just adding a simple term to an existing equation, scientists can produce far better mass estimates than they previously had. The improved estimates will enable scientists to calculate the fundamental properties of the universe more accurately, the astrophysicists have reported.
Published AI finds the first stars were not alone
(via sciencedaily.com) Machine learning and state-of-the-art supernova nucleosynthesis has helped researchers find that the majority of observed second-generation stars in the universe were enriched by multiple supernovae.
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 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 Neutrinos made by a particle collider detected
(via sciencedaily.com) Physicists have detected neutrinos created by a particle collider. The discovery promises to deepen scientists' understanding of the subatomic particles, which were first spotted in 1956 and play a key role in the process that makes stars burn.
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 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 Electronic skin as flexible as crocodile skin
(via sciencedaily.com) A research team has developed a crocodile-skin-inspired omnidirectionally stretchable pressure sensor.
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 Extensive catalog of exploding stars
(via sciencedaily.com) The largest data release of relatively nearby supernovae (colossal explosions of stars), containing three years of data is publicly available via the Young Supernova Experiment (YSE).
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.
Published Webb Telescope captures rarely seen prelude to supernova
(via sciencedaily.com) The rare sight of a Wolf-Rayet star -- among the most luminous, most massive, and most briefly detectable stars known -- was one of the first observations made by NASA's James Webb Space Telescope in June 2022. Webb shows the star, WR 124, in unprecedented detail with its powerful infrared instruments. The star is 15,000 light-years away in the constellation Sagittarius.
Published Robots can help improve mental wellbeing at work -- as long as they look right
(via sciencedaily.com) Robots can be useful as mental wellbeing coaches in the workplace -- but perception of their effectiveness depends in large part on what the robot looks like.
Published Spatial patterns in distribution of galaxies
(via sciencedaily.com) In an unlikely pairing, a chemist and an astrophysicist applied the tools of statistical mechanics to find similarities in spatial patterns across length scales.
