Researchers have identified a new material which could be used as a flexible semiconductor in wearable devices by using a technique that focuses on the manipulation of spaces between atoms in crystals.

Most people generally are more concerned about the immediate risks of artificial intelligence than they are about a theoretical future in which AI threatens humanity. A new study reveals that respondents draw clear distinctions between abstract scenarios and specific tangible problems and particularly take the latter very seriously.

Smartphones may often feel like a source of stress, feeding us an endless stream of bad news and social comparison. But what if they could also be the solution? A team of researchers believes they can be. The team has developed a smartphone app that delivers core techniques of cognitive-behavioral therapy (CBT) -- a proven treatment for depression and anxiety -- straight into the hands of users, and tested it in the largest-ever individually randomized trial of its kind. Their resilience training app, called RESiLIENT, was tested on nearly 4,000 adults across Japan experiencing subthreshold depression -- a form of low-level but persistent depressive symptoms that doesn't meet criteria for major depressive disorder but can still be debilitating. This condition affects an estimated 11% of people worldwide and often goes untreated.

Engineers developed a technique to grow and peel ultrathin 'skins' of electronic material that could be used in applications such as night-vision eyewear and autonomous driving in foggy conditions.

The invention is a metamaterial, which is a material engineered to feature new and unusual properties that depend on the material's physical structure rather than its chemical composition. In this case, the researchers built their metamaterial using a combination of simple plastics and custom-made magnetic composites. Using a magnetic field, the researchers changed the metamaterial's structure, causing it to expand, move and deform in different directions, all remotely without touching the metamaterial.

Researchers have developed a new robotic framework powered by artificial intelligence -- called RHyME (Retrieval for Hybrid Imitation under Mismatched Execution) -- that allows robots to learn tasks by watching a single how-to video.

With the assumption that students are going to use artificial intelligence and large language models such as ChatGPT to do their homework, researchers set out to learn how well the free version of ChatGPT would compare with human students in a semester-long undergraduate control systems course.

Researchers have developed a new artificial intelligence (AI) technique that brings machine vision closer to how the human brain processes images. Called Lp-Convolution, this method improves the accuracy and efficiency of image recognition systems while reducing the computational burden of existing AI models.

A powerful clinical artificial intelligence tool developed by biomedical informatics researchers has demonstrated remarkable accuracy on all three parts of the United States Medical Licensing Exam (Step exams), according to a new article.

Working memory is like a mental chalkboard we use to store temporary information while executing other tasks. Scientists worked with more than 200 elementary students to test their working memory, assess its role in word-problem solving and if interventions could boost it and thereby improve their word problem solving skills. Results showed that improving working memory helped both students with and without math difficulties and can help educators more effectively by helping teach the science of math, study authors argue.

Researchers observe over a dozen never-before-seen quantum states in a unique quantum material.

Saying one thing while feeling another is part of being human, but bottling up emotions can have serious psychological consequences like anxiety or panic attacks. To help health care providers tell the difference, a team has created a stretchable, rechargeable sticker that can detect real emotions -- by measuring things like skin temperature and heart rate -- even when users put on a brave face.

A new study by biomedical engineers and neuroscientists shows that the brain's visual regions play an active role in making sense of information.

A team of researchers has developed a new way to control light interactions using a specially engineered structure called a 3D photonic-crystal cavity that could enable transformative advancements in quantum computing, quantum communication and other quantum-based technologies.

Sticking to an exercise routine is a challenge many people face. But a research team is using machine learning to uncover what keeps individuals committed to their workouts.

A research team conducted a meta-analysis of the diagnostic capabilities of generative AI in the field of medicine using 83 research papers.

An international research team has discovered the anomalous Hall effect in a collinear antiferromagnet. More strikingly, the anomalous Hall effect emerges from a non-Fermi liquid state, in which electrons do not interact according to conventional models. The discovery not only challenges the textbook framework for interpreting the anomalous Hall effect but also widens the range of antiferromagnets useful for information technologies.

A study has found a rare form of one-dimensional quantum magnetism in a metallic compound, offering evidence into a phase space that has remained, until now, largely theoretical. The study comes at a time of growing global interest in quantum materials that redefine the boundaries between magnetism, conductivity, and quantum coherence.

Researchers have demonstrated a significant performance increase in cooling technology for high-power electronic devices. They designed novel capillary geometries that push the boundaries of thermal transfer efficiency. This study could play a crucial role in the development of next-generation technology.

Scientists have created the first neutron 'Airy beam,' which has unusual capabilities that ordinary neutron beams do not. The achievement could enhance neutron-based techniques for investigating the properties of materials that are difficult to explore by other means. For example, the beams can probe characteristics of molecules such as chirality, which is important in biotechnology, chemical manufacturing, quantum computing and other fields.
