Squid-inspired robot swims with nature’s most efficient marine animals

Scientists at the University of Southampton and University of Edinburgh have developed a flexible underwater robot that can propel itself through water in the same style as nature’s most efficient swimmer – the Aurelia aurita jellyfish. The findings, published in Science Robotics, demonstrate that the new underwater robot can swim as quickly and efficiently as […]

Tweaking AI software to function like a human brain improves computer’s learning ability

WASHINGTON – Computer-based artificial intelligence can function more like human intelligence when programmed to use a much faster technique for learning new objects, say two neuroscientists who designed such a model that was designed to mirror human visual learning. In the journal Frontiers in Computational Neuroscience, Maximilian Riesenhuber, PhD, professor of neuroscience, at Georgetown University […]

3D-printed smart gel changes shape when exposed to light

Powerful ‘unsupervised’ machine learning involves […]

Spontaneous robot dances highlight a new kind of order in active matter

IMAGE: When a swarm of smarticles is made to interact in a confined space, they form stunningly symmetric dances whose choreography emerges spontaneously from the physics of low rattling. view more  Credit: Thomas A. Berrueta Predicting when and how collections of particles, robots, or animals become orderly remains a challenge across science and engineering. In the […]

Army research leads to more effective training model for robots

IMAGE: New Army research reduces the unpredictability of current training reinforcement learning policies so that they are more practically applicable to physical systems, especially ground robots. These learning components will permit… view more  Credit: (Photo illustration / U.S. Army) ADELPHI, Md. — Multi-domain operations, the Army’s future operating concept, requires autonomous agents with learning components to […]

New mammogram measures of breast cancer risk could revolutionise screening

World-first techniques for predicting breast cancer risk from mammograms that were developed in Melbourne could revolutionise breast screening by allowing it to be tailored to women at minimal extra cost. Published in the International Journal of Cancer, the University of Melbourne-led study found two new mammogram-based measures of risk. When these measures are combined, they […]

AI-designed serotonin sensor may help scientists study sleep and mental health

Serotonin is a neurochemical that plays a critical role in the way the brain controls our thoughts and feelings. For example, many antidepressants are designed to alter serotonin signals sent between neurons. In an article in Cell, National Institutes of Health-funded researchers described how they used advanced genetic engineering techniques to transform a bacterial protein […]

AI-supported test predicts eye disease three years before symptoms
