A new method significantly advances 3D imaging of reflective surfaces. The approach integrates techniques known from high-precision optical 3D metrology and computer vision, and could benefit applications ranging from industrial inspection and medical imaging to virtual reality and cultural heritage preservation.

Researchers asked generative AI to write a research paper. While adept at some steps, it wholly failed at others.

Researchers conducted the first clinical trial of an AI-powered therapy chatbot and found that, on average, people with diagnosed mental disorders experienced clinically significant improvements in their symptoms over eight weeks, according to new results. Users engaged with the software, known as Therabot, through a smartphone app and reported that interactions were comparable to working with a mental-health professional. The researchers conclude that while AI-powered therapy is in critical need of clinician oversight, it has the potential to provide real-time support for the many people who lack regular or immediate access to a professional.

Most haptic devices only deliver feedback as simple vibrations. New device applies dynamic forces in any direction to simulate a more realistic sense of touch. Small, lightweight device can enhance virtual reality, help individuals with visual impairments, provide tactile feedback for remote health visits and more.

At hypersonic speeds, complexities occur when the gases interact with the surface of the vehicle such as boundary layers and shock waves. Researchers were able to observe new disturbances in simulations conducted for the first time in 3D.

A tiny magnetic robot which can take 3D scans from deep within the body, that could revolutionize early cancer detection, has been developed by researchers. The team say this is the first time it has been possible to generate high-resolution three-dimensional ultrasound images taken from a probe deep inside the gastrointestinal tract, or gut.

Researchers have developed 'tomoseqr' -- a new software tool that enables easy estimation of the three-dimensional (3D) spatial distribution of gene expression. Tomoseqr is free to use and has been integrated into Bioconductor -- a widely used international platform for life science software. This innovative tool will potentially help researchers identify key genes involved in organism development, disease mechanisms, and regenerative biology.

Electrical and computer engineers have developed a 'Super-Turing AI,' which operates more like the human brain. This new AI integrates certain processes instead of separating them and then migrating huge amounts of data like current systems do.

A novel method to improve the photoluminescent efficiency of metal clusters has been developed -- which could potentially be used in applications such as bioimaging or display technologies.

Quantum computers are able to solve complex calculations that would take traditional computers thousands of years in just a few minutes. What if that analytical power is turned inwards towards the computer itself?

Nature documentaries presented as 360 virtual reality videos have a stronger positive effect than other forms of media, including an indirect effect on donation intentions.

A new study shows that people in Japan treat robots and AI agents more respectfully than people in Western societies.

New research has found that employers and policymakers might want to start paying attention to how workers are feeling, because employee happiness contains critical economic information.

Scientists have created a smart insoles prototype that can accurately measure the body's interaction with the ground, which has the potential to help athletes avoid injuries, or even assist doctors in monitoring recovery.

People with autism are typically diagnosed by clinical observation and assessment. To deconstruct the clinical decision process, which is often subjective and difficult to describe, researchers used a large language model (LLM) to synthesize the behaviors and observations that are most indicative of an autism diagnosis. Their results show that repetitive behaviors, special interests, and perception-based behaviors are most associated with an autism diagnosis. These findings have potential to improve diagnostic guidelines for autism by decreasing the focus on social factors -- which the established guidelines in the DSM-5 focus on but the model did not classify among the most relevant in diagnosing autism.

A flower-shaped structure only a few micrometres in size made of a nickel-iron alloy can concentrate and locally enhance magnetic fields. The size of the effect can be controlled by varying the geometry and number of 'petals'. This magnetic metamaterial developed by Dr Anna Palau's group at the Institut de Ciencia de Materials de Barcelona (ICMAB) in collaboration with her partners of the CHIST-ERA MetaMagIC project, has now been studied at BESSY II in collaboration with Dr Sergio Valencia. Such a device can be used to increase the sensitivity of magnetic sensors, to reduce the energy required for creating local magnetic fields, but also, at the PEEM experimental station, to study samples under much higher magnetic fields than currently possible.

From virtual reality to rehabilitation and communication, haptic technology has revolutionized the way humans interact with the digital world. While early haptic devices focused on single-sensory cues like vibration-based notifications, modern advancements have paved the way for multisensory haptic devices that integrate various forms of touch-based feedback, including vibration, skin stretch, pressure and temperature. Recently, a team of experts analyzed the current state of wearable multisensory haptic technology, outlining its challenges, advancements and real-world applications.

Researchers presented advances shaping the world of forensics, from research that could improve how forensic scientists estimate a person's age at death, to technology demos of CSIxR -- a virtual reality (VR) application that simulates crime scenes scenarios to train crime scene investigators (CSIs).
