Remote Transmission of Smells

Researchers from Ohio State University have developed Scentronic, an innovative digital scent technology capable of detecting and recreating aromas remotely through the internet. The system combines an electronic nose equipped with chemical sensors and artificial intelligence to identify specific smells, such as coffee, oranges, cake, beer, and red wine. Once identified, the scent information is transmitted digitally to a remote device that releases corresponding fragrances. Researchers have developed compact scent generators in wearable formats, including wristbands and necklaces, potentially introducing smell as a new dimension of digital communication alongside sight and sound.

The technology could significantly enhance XR, online shopping, and remote social interactions by enabling users to experience scents associated with virtual environments, products, or distant locations. However, Scentronic remains an experimental prototype with several limitations, including its ability to recognize only five predefined aromas and the challenge of accurately reproducing complex smells. Further research is needed to expand its scent library, improve recognition accuracy, miniaturize devices, and address safety and manufacturing considerations. Despite these challenges, the development represents a promising step toward more immersive, multisensory digital experiences.

Seven-Minute VR Experience Reduces Student Stress and Exam Anxiety

A new study from City St George’s, University of London, demonstrates that a seven-minute VR intervention can significantly reduce stress and exam anxiety among students. Researchers recruited 131 healthcare students and randomly assigned them to experience a relaxation programme either through VR headsets or smartphones over five consecutive days. The programme combined breathing exercises, visualisation, positive coping strategies, and immersive audiovisual environments. Although both groups experienced improvements, VR participants reported significantly greater reductions in stress and anxiety, alongside increased calmness and happiness. These benefits also included lower perceived stress levels at a two-week follow-up.

The findings highlight VR's potential as an accessible and effective tool for supporting student mental health. Notably, 89% of VR participants reported meaningful emotional benefits, compared with just 34% of smartphone users. Students described feeling more focused, confident, and capable of managing academic pressures, with some reporting improved sleep and productivity. Researchers suggest that short, immersive VR sessions could be integrated into educational well-being programmes, providing students with practical stress-management strategies before anxiety becomes overwhelming. The study demonstrates the promising role of immersive technologies in promoting psychological well-being and academic resilience.

Gene Therapy and Special Goggles Restore Limited Vision in Blind Patients

Scientists have developed an experimental treatment combining gene therapy with specialised goggles to restore limited vision in people affected by retinitis pigmentosa, a genetic disease that progressively destroys the retina’s light-sensitive cells. The treatment uses optogenetics, a technique that introduces a light-sensitive protein called ChrimsonR into retinal ganglion cells, enabling them to respond to light. Special goggles capture visual information and convert it into pulses of amber light that stimulate these modified cells, allowing visual signals to reach the brain. In a study, seven of ten participants experienced improved light sensitivity, demonstrating the potential of this approach to partially restore sight.

The results represent a promising advance in treating inherited blindness. Four of eight participants who completed behavioural testing could perform basic visual tasks, such as locating doorways or following lines, while wearing the goggles. However, the restored vision remains limited, with participants unable to recognise faces or read text. The treatment also requires an intact optic nerve to transmit visual information to the brain, restricting its suitability for certain forms of blindness. Despite these limitations, researchers consider the findings an important proof of concept and hope that further improvements will enable more sophisticated visual abilities.

Brain Implants Offer New Hope for Restoring Speech

Scientists are developing brain implants that help people who have lost their ability to speak due to conditions such as ALS, Parkinson’s disease, strokes and brain injuries. BCIs, detect electrical signals from the brain and use artificial intelligence to translate them into words or speech. One remarkable example is an ALS patient who received brain implants in 2023. Technology has allowed him to communicate nearly two million words, reconnect with his family and participate in everyday conversations. Researchers are also developing systems that can produce speech almost instantly, bringing them closer to restoring natural communication.

Despite these breakthroughs, technology remains experimental and faces challenges, including high costs, invasive surgery, limited portability and occasional inaccuracies in translating brain signals. Scientists are working on smaller wireless implants and more advanced AI systems that could reproduce natural speech patterns, emotions and gestures. Although widespread availability is not guaranteed, researchers believe these innovations could dramatically improve the quality of life for people with severe speech impairments, restoring not only their ability to communicate but also their independence and personal connections.

XREAL 1 Pro+

REAL has officially launched its new flagship augmented reality glasses, the XREAL 1 Pro+, priced at $599, introducing several improvements over the original One Pro released in 2025. The updated glasses feature significantly brighter Sony micro-OLED displays, increasing peak brightness from 700 to 1,200 nits, alongside AI-powered High Dynamic Range technology for enhanced image quality. The device retains its 1920 × 1080 resolution per eye, 57-degree field of view, 120Hz refresh rate, and proprietary X1 spatial computing chip. Additional enhancements include a redesigned ergonomic nose pad system for improved comfort and stability, while maintaining Bose-powered audio and 3DOF spatial tracking.

A notable advancement is the improved real-time 2D-to-3D content conversion, which now operates at 60 frames per second instead of 30, enabling smoother immersive viewing experiences. Although the XREAL 1 Pro+ resembles standalone smart glasses, it still requires a USB-C connection to compatible smartphones, laptops, or gaming devices. The glasses also support optional six degrees of freedom (6DOF) tracking through an external accessory. Available from October 15, 2026, the XREAL 1 Pro+ represents an incremental but meaningful upgrade, focusing on visual quality, spatial viewing, and user comfort rather than introducing an entirely new hardware platform.

The Walking Robotic Hand

Researchers at ETH Zurich have developed an innovative autonomous robotic hand capable of walking on its fingers while simultaneously performing manipulation tasks. Unlike conventional robotic systems that require separate mechanisms for mobility and object interaction, this approach transforms a commercially available five-fingered robotic hand into a self-contained mobile robot. Using AI and reinforcement learning, the researchers trained the hand in simulation to navigate different surfaces, maintain balance, recover from falls, press keyboard keys, and push objects. Equipped with a compact onboard computer, battery, and motion sensors, the robotic hand successfully traversed 14 different surfaces, achieved an average walking speed of 9 centimetres per second, and demonstrated autonomous object manipulation. Its learning framework addresses the challenges posed by the hand's asymmetrical structure, enabling coordinated finger movements for both locomotion and manipulation.

The research introduces a promising direction for autonomous modular robotics, where individual robotic components can dynamically switch between different functions rather than remaining permanently assigned to specific tasks. Potential applications include industrial maintenance, inspection of confined environments, search-and-rescue operations, and advanced robotic manipulation in spaces inaccessible to conventional robotic arms. By combining mobility, dexterity, and intelligent control within a single compact platform, the technology could contribute to a new generation of adaptable, multifunctional robotic systems. Nevertheless, challenges remain regarding autonomous perception, navigation, mechanical durability, and reliability in complex environments. The broader vision is to develop robotic architectures in which individual components can operate independently or collaboratively, improving flexibility and adaptability across real-world applications.

Wearable Human Body

Engineers at Georgia Tech’s College of Engineering have developed a wireless system that allows wearable devices and tiny medical implants to communicate directly through the body’s tissues. Called SWANS (Smart Wireless Autonomous Networking System), the technology takes inspiration from the nervous system and uses the body’s natural ionic conductivity to transmit small electrical signals. Unlike conventional Bluetooth or NFC connections, which struggle to penetrate tissue and require relatively large antennas and substantial power, SWANS enables sensors and therapeutic devices located in different parts of the body to coordinate without being physically connected or positioned close together.

The researchers demonstrated the approach by creating a network of sensors and neural interfaces that coordinated limb movement in an animal model. Because the system requires very little power, implants can be made smaller than 3 millimeters, potentially allowing them to be inserted using a syringe rather than surgery. Sensors could eventually detect biological changes and automatically instruct another device to deliver medication, stimulate a nerve, or perform another therapeutic action at the appropriate location. Researchers vision SWANS as a step toward personalized bioelectronic medicine in which distributed sensors, wearables, and implants work together to monitor health and deliver treatments when needed.
