Published How teachers make ethical judgments when using AI in the classroom
(via sciencedaily.com) Original source A teacher's gender and comfort with technology factor into whether artificial intelligence is adopted in the classroom, as shown in a new report.
Published One person can supervise 'swarm' of 100 unmanned autonomous vehicles
(via sciencedaily.com) Original source Research involving has shown that a 'swarm' of more than 100 autonomous ground and aerial robots can be supervised by one person without subjecting the individual to an undue workload.
Published Ultra-sensitive lead detector could significantly improve water quality monitoring
(via sciencedaily.com) Original source Engineers have developed an ultra-sensitive sensor made with graphene that can detect extraordinarily low concentrations of lead ions in water. The device achieves a record limit of detection of lead down to the femtomolar range, which is one million times more sensitive than previous technologies.
Published AI learns through the eyes and ears of a child
(via sciencedaily.com) Original source Researchers have been skeptical that recent AI advances can tell us much about human learning and development. To address this, a team training an AI model, not on massive data, but on the input that a single child receives. Their findings showed that the model could learn a substantial number of words and concepts using limited slices of what the child experienced.
Published Key dynamics of 2D nanomaterials: View to larger-scale production
(via sciencedaily.com) Original source A team of researchers mapped out how flecks of 2D materials move in liquid -- knowledge that could help scientists assemble macroscopic-scale materials with the same useful properties as their 2D counterparts.
Published Machine learning guides carbon nanotechnology
(via sciencedaily.com) Original source Carbon nanostructures could become easier to design and synthesize thanks to a machine learning method that predicts how they grow on metal surfaces. The new approach will make it easier to exploit the unique chemical versatility of carbon nanotechnology.
Published How does a 'reverse sprinkler' work? Researchers solve decades-old physics puzzle
(via sciencedaily.com) Original source For decades scientists have been trying to solve Feynman's Sprinkler Problem: How does a sprinkler running in reverse work? Through a series of experiments, a team of mathematicians has figured out how flowing fluids exert forces and move structures, thereby revealing the answer to this long-standing mystery.
