With the help of VR glasses and playful exercises, tele-rehabilitation of patients is to be made more effective and attractive.

Scientists at the Autonomous University of Madrid (UAM) argue that the most exotic and complex quantum phenomena occur at frequencies where quantum systems emit the least light. The work opens new doors for the development of advanced quantum technologies by studying correlations of multiple photons emitted by qubits (atoms or other two-electron systems).

Sleep apnoea, a condition marked by pauses in breathing during sleep, affects millions of people worldwide, leading to severe health risks, including heart disease, stroke, and diabetes. Traditionally, diagnosing this condition requires an overnight stay at a clinic for polysomnography (PSG) tests, which are costly, complex, and uncomfortable as they involve attaching multiple sensors to the body, making it difficult to sleep naturally.

Breakthrough research that eliminates the guesswork in developing advanced 3D printed materials could help accelerate the development of new forms of 'self-sensing' aeroplanes, robots, bridges and more. A team of engineers led by researchers from the University of Glasgow have developed the first system capable of modelling the complex physics of 3D-printed composites capable of detecting strain, load, and damage using nothing more than a measure of electrical current.

University of Waterloo engineers are turning to augmented/virtual reality (AR/VR) to better understand - and maintain - the physical reality of Canada's critical infrastructure.

Help in the search for missing persons: New JKU method enables three-dimensional perception of drone images in real time. This works even with strong occlusion and at long distances. Human visual depth perception, i.e. the ability to perceive objects at different distances, is essentially based on the fact that our eyes see slightly different images in terms of perspective.

Cyrille Herkert defended her PhD thesis at the Department of Industrial Design on September 24th. With her doctoral research, Cyrille Herkert, PhD candidate and cardiologist-in-training, offers new insights that can help improve care for heart failure patients using technology and telemonitoring.

From detecting cancer in medical imaging to recommending additional lesson plans for students in K-12 education, algorithm technologies have become crucial across many different industries. Whether algorithms lead to improved efficiency is another question, according to University of Michigan researchers.

Thanks to innovations in design, control and production technology, brushless drives for pumps and fan systems work more efficiently and quietly. Users of electrical appliances and the automotive industry do benefit. Small electric motors can be found in many household appliances, tools and computers as well as in modern cars, where they drive auxiliary units such as pumps and fans.

A new EPFL paper has found that students are cautious towards AI feedback, highlighting the complexity of integrating it into educational feedback systems. Feedback plays a crucial role in learning, helping individuals to understand and improve their performance, yet globally large and diverse student populations often mean that providing timely and personalized observations can be a challenge.

Thinner than a human hair, the device amplifies and converts near infrared light into visible light with the potential for low power consumption and long battery life Study: Positive feedback organic light-emitting diodes and upconverter s (DOI: 10.1038/s41566'024 -01520-0) A new type of OLED (organic light emitting diode) could replace bulky night vision goggles with lightweight glasses, making them cheaper and more practical for prolonged use, according to University of Michigan researchers.

The emotional tone of written language, as assessed by people or ChatGPT, can predict changes in depressive symptoms three weeks later. A person's choice of words can be predictive of worsening symptoms of major depressive disorder, a new Yale study finds. Using both human evaluators and the large language model ChatGPT, researchers demonstrated that written responses to open-ended questions could be used to predict who would experience worse symptoms of depression weeks later.

A Western study could help farmers get out of a potential jam by using artificial intelligence (AI) and passive camera monitoring to enhance strawberry cultivation. In a paper published in the international journal Foods , Western engineers describe a new machine-learning approach that yields the highest-ever precision and accuracy rates for ripeness and disease detection in strawberries of any previous attempts.

The University of Waterloo has long been renowned for entrepreneurship and innovation and for providing co-operative education (co-op) and work-integrated learning at scale with impact. Dr. Margaret Dalziel and Nada Basir, both professors at the Conrad School of Business and Entrepreneurship, conducted a study into the mechanisms behind this success, revealing that co-op plays a pivotal role in shaping the ventures of student entrepreneurs.

Researchers at the University of Waterloo have designed an energy-efficient device that produces drinking water from seawater using an evaporation process driven largely by the sun. Desalination is critical for many coastal and island nations to provide access to fresh water, given water scarcity concerns due to rapid population growth and increasing global water consumption.

A new technology that uses light waves to measure activity in babies' brains has provided the most complete picture to date of functions like hearing, vision and cognitive processing outside a conventional brain scanner, in a new study led by researchers at UCL and Birkbeck.

University of Queensland researchers are developing new ways to monitor mine waste using drones and ground sensors to improve safety and land rehabilitation across mine sites. Lead investigator Dr Thierry Bore from the School of Civil Engineering said safe management and rehabilitation of mine waste was one of the biggest challenges facing the industry.

An international team of researchers led by Maximilian Weißflog, with the participation of researchers from Jena, Canberra and with support from Darmstadt, has made a significant advance in quantum optics. In their latest publication in the renowned journal "Nature", the team presents a novel method for generating entangled photon pairs using two-dimensional (2D) materials.

Using 3D printing technology and ultrasonic joining technique, researchers at TU Graz succeeded in attaining an extremely strong joining of the renewable raw material wood with metal and polymer composite. The renewable raw material wood is climate-neutral and at the same time light and strong, making it fundamentally attractive for use in vehicle manufacturing.

An external study of Twitter in 2022 estimated that between a third and two thirds of accounts on the social media site were bots. And many of these automatons flooding social media are dispatched to sow political polarization, hate, misinformation, propaganda and scams. The ability to sift them out of the online crowds is vital for a safer, more humane (or at least more human) internet.
