Published Project aims to expand language technologies
(via sciencedaily.com) Only a fraction of the 7,000 to 8,000 languages spoken around the world benefit from modern language technologies like voice-to-text transcription, automatic captioning, instantaneous translation and voice recognition. Researchers want to expand the number of languages with automatic speech recognition tools available to them from around 200 to potentially 2,000.
Published Enabling nanoscale thermoelectrics with a novel organometallic molecular junction
(via sciencedaily.com) Multinuclear organometallic junctions might be the key to realizing high-performance thermoelectric devices at the nanoscale. The unique electronic structure of organometallic ruthenium alkynyl complexes allowed the researchers to achieve unprecedented heat-to-electricity conversion performance in molecular junctions, paving the way to molecular-scale temperature sensors and thermal energy harvesters.
Published Cheap, sustainable hydrogen through solar power
(via sciencedaily.com) A new kind of solar panel has achieved 9% efficiency in converting water into hydrogen and oxygen--mimicking a crucial step in natural photosynthesis. Outdoors, it represents a major leap in the technology, nearly 10 times more efficient than solar water-splitting experiments of its kind.
Published Scientists develop a cool new method of refrigeration
(via sciencedaily.com) Researchers have developed a new kind of heating and cooling method that they have named the ionocaloric refrigeration cycle. They hope the technique will someday help phase out refrigerants that contribute to global warming and provide safe, efficient cooling and heating for homes.
Published Can the AI driving ChatGPT help to detect early signs of Alzheimer's disease?
(via sciencedaily.com) The artificial intelligence algorithms behind the chatbot program ChatGPT -- which has drawn attention for its ability to generate humanlike written responses to some of the most creative queries -- might one day be able to help doctors detect Alzheimer's Disease in its early stages. Research recently demonstrated that OpenAI's GPT-3 program can identify clues from spontaneous speech that are 80% accurate in predicting the early stages of dementia.
Published Words prove their worth as teaching tools for robots
(via sciencedaily.com) What is the best way to teach a robot? Sometimes it may simply be to speak to it clearly. Researchers found that human-language descriptions of tools can accelerate the learning of a simulated robotic arm lifting and using a variety of tools.
Published Cheerful chatbots don't necessarily improve customer service
(via sciencedaily.com) Humans displaying positive emotions in customer service interactions have long been known to improve customer experience, but researchers wanted to see if this also applied to AI. They conducted experimental studies to determine if positive emotional displays improved customer service and found that emotive AI is only appreciated if the customer expects it, and it may not be the best avenue for companies to invest in.
Published Should we tax robots?
(via sciencedaily.com) A small tax on robots, as well as on trade generally, will help reduce income inequality in the U.S., according to economists.
Published New winged robot can land like a bird
(via sciencedaily.com) Researchers have developed a method that allows a flapping-wing robot to land autonomously on a horizontal perch using a claw-like mechanism. The innovation could significantly expand the scope of robot-assisted tasks.
Published A shield for 2D materials that adds vibrations to reduce vibration problems
(via sciencedaily.com) A new study demonstrates a new, counterintuitive way to protect atomically-thin electronics -- adding vibrations, to reduce vibrations. By squeezing a liquid-metal gallium droplet, graphene devices are painted with a protective coating of gallium-oxide that can cover millimeter-wide scales, making it potentially applicable for industrial large-scale fabrication. The new technique improves device performance as well as protecting 2D materials from thermal vibration in neighboring materials.
Published Mitigating corrosion by liquid tin could lead to better cooling in fusion reactors
(via sciencedaily.com) Researchers have clarified the chemical compatibility between high temperature liquid metal tin (Sn) and reduced activation ferritic martensitic, a candidate structural material for fusion reactors. This discovery has paved the way for the development of a liquid metal tin divertor, which is an advanced heat-removal component of fusion reactors. A device called a divertor is installed in the fusion reactors to maintain the purity of the plasma. For divertors, there has been demand for liquid metals that can withstand extremely large heat loads from high-temperature plasma.
Published New robot does 'the worm' when temperature changes
(via sciencedaily.com) A new gelatinous robot that crawls, powered by nothing more than temperature change and clever design, brings 'a kind of intelligence' to the field of soft robotics.
Published Chaos gives the quantum world a temperature
(via sciencedaily.com) Two seemingly different areas of physics are related in subtle ways: Quantum theory and thermodynamics. How can the laws of thermodynamics arise from the laws of quantum physics? This question has now been pursued with computer simulations, which showed that chaos plays a crucial role: Only where chaos prevails do the well-known rules of thermodynamics follow from quantum physics.
Published Model shows how intelligent-like behavior can emerge from non-living agents
(via sciencedaily.com) A new model describes how biological or technical systems form complex structures equipped with signal-processing capabilities that allow the systems to respond to stimulus and perform functional tasks without external guidance.
Published Bolstering the safety of self-driving cars with a deep learning-based object detection system
(via sciencedaily.com) Self-driving cars need to implement efficient, effective, and accurate detection systems to provide a safe and reliable experience to its users. To this end, an international research team has now developed an end-to-end neural network that, in conjunction with the Internet-of-Things technology, detects object with high accuracy (> 96%) in both 2D and 3D. The new method outperforms the current state-of-the-art methods and the way to new 2D and 3D detection systems for autonomous vehicles.
Published Gold-based passive heating for eyewear
(via sciencedaily.com) Researchers have developed a new transparent gold nanocoating that harnesses sunlight to heat the lenses of glasses, thereby preventing them from fogging in humid conditions. This coating could potentially also be applied to car windshields.
Published Computer vision technology effective at determining proper mask wearing in a hospital setting, pilot study finds
(via sciencedaily.com) In a survey and study of hospital employee volunteers, researchers found that a low-cost computer vision system was feasible and well received.
Published Soft robot detects damage, heals itself
(via sciencedaily.com) Engineers have created a soft robot capable of detecting when and where it was damaged -- and then healing itself on the spot.
Published Flameproofing lithium-ion batteries with salt
(via sciencedaily.com) A polymer-based electrolyte makes for batteries that keep working -- and don't catch fire -- when heated to over 140 degrees F.
