Trash-sorting robot mimics complex human sense of touch      (via sciencedaily.com)     Original source 

Researchers are breaking through the difficulties of robotic recognition of various common, yet complex, items. Their layered sensor is equipped with material detection at the surface and pressure sensitivity at the bottom, with a porous middle layer sensitive to thermal changes. An efficient cascade classification algorithm rules out object types in order, from easy to hard, starting with simple categories like empty cartons before moving on to orange peels or scraps of cloth.

Four-legged, dog-like robot 'sniffs' hazardous gases in inaccessible environments      (via sciencedaily.com)     Original source 

Nightmare material or truly man's best friend? A team of researchers equipped a dog-like quadruped robot with a mechanized arm that takes air samples from potentially treacherous situations, such as an abandoned building or fire. The robot dog walks samples to a person who screens them for potentially hazardous compounds.

Liquid metal-based electronic logic device that mimics intelligent prey-capture mechanism of Venus flytrap      (via sciencedaily.com)     Original source 

A research team has developed a liquid metal-based electronic logic device that mimics the intelligent prey-capture mechanism of Venus flytraps. Exhibiting memory and counting properties, the device can intelligently respond to various stimulus sequences without the need for additional electronic components. The intelligent strategies and logic mechanisms in the device provide a fresh perspective on understanding 'intelligence' in nature and offer inspiration for the development of 'embodied intelligence'.

People feel more connected to 'tweezer-like' bionic tools that don't resemble human hands      (via sciencedaily.com)     Original source 

Some say the next step in human evolution will be the integration of technology with flesh. Now, researchers have used virtual reality to test whether humans can feel embodiment -- the sense that something is part of one's body -- toward prosthetic 'hands' that resemble a pair of tweezers. They report that participants felt an equal degree of embodiment for the tweezer-hands and were also faster and more accurate in completing motor tasks in virtual reality than when they were equipped with a virtual human hand.

Babies use 'helpless' infant period to learn powerful foundation models, just like ChatGPT      (via sciencedaily.com)     Original source 

Babies' brains are not as immature as previously thought, rather they are using the period of postnatal 'helplessness' to learn powerful foundation models similar to those underpinning generative Artificial Intelligence, according to a new study.

Enhancing nanofibrous acoustic energy harvesters with artificial intelligence      (via sciencedaily.com)     Original source 

Scientists have employed artificial intelligence techniques to improve the design and production of nanofibers used in wearable nanofiber acoustic energy harvesters (NAEH). These acoustic devices capture sound energy from the environment and convert it into electrical energy, which can then be applied in useful devices, such as hearing aids.

Public have no difficulty getting to grips with an extra thumb, study finds      (via sciencedaily.com)     Original source 

Researchers have shown that members of the public have little trouble in learning very quickly how to use a third thumb -- a controllable, prosthetic extra thumb -- to pick up and manipulate objects. The team tested the robotic device on a diverse range of participants, which they say is essential for ensuring new technologies are inclusive and can work for everyone.

Close to 1 in 2 surveyed say they would use air taxis in the future      (via sciencedaily.com)     Original source 

Through a study of 1,002 participants, scientists have found that almost half (45.7 per cent) say they intend to use air taxis when they become available, with over one-third (36.2 per cent) planning to do so regularly. According to the findings, the intention to take autonomous air taxis is associated with factors such as trust in the AI technology deployed in air taxis, hedonic motivation (the fun or pleasure derived from using technology), performance expectancy (the degree to which users expect that using the system will benefit them), and news media attention (the amount of attention paid to news about air taxis).
