Augmented-reality (AR) technology is rapidly finding its way into everyday life, from education and healthcare to gaming and entertainment. However, the core AR device remains bulky and heavy, making prolonged wear uncomfortable. A breakthrough now promises to change that. A research team has slashed both thickness and weight using a single-layer waveguide.

Global emissions of carbon dioxide from industry can be reduced by five per cent. But that requires companies and policy makers to take a holistic approach to energy efficiency and energy management and not solely focus on technological development.

The rules about magnetic order may need to be rewritten. An international team of researchers found that it was possible to turn a non-magnetic material into a magnetic material by slicing it into thin films.

A team of researchers has unveiled a cutting-edge Amphibious Robotic Dog capable of roving across both land and water with remarkable efficiency.

Data science has revolutionized the hunt for high-performing catalysts, enabling scientists to quickly identify and test suitable materials.

Fishing pots fitted with LED lights catch significantly more shrimp and fish, new research shows.

A new study of the 28 most populous U.S. cities finds that all are sinking to one degree or another. The cities include not just those on the coasts, where relative sea level is a concern, but many in the interior. Furthermore, using newly granular data, the study finds that some cities are sinking at different rates in different spots, or sinking in some places and rising in others, potentially introducing stresses that could affect buildings and other infrastructure.

Scientists have developed a new microscope that significantly improves the way heat flow in materials can be measured. This advancement could lead to better designs for electronic devices and energy systems.

An edible robot leverages a combination of biodegradable fuel and surface tension to zip around the water's surface, creating a safe -- and nutritious -- alternative to environmental monitoring devices made from artificial polymers and electronics.

Scientists have engineered a monoclonal antibody that can protect mice from a lethal dose of influenza A, a new study shows. The new molecule combines the specificity of a mature flu fighter with the broad binding capacity of a more general immune system defender.

Redesigning social media to suit different needs of users could make their time online more focused, according to new research.

Using a thermal sensor smaller than a grain of sand, engineers have measured the vibrations, or phonons, within individual molecules.

A new technique to extract tiny cellulose strands from cow dung and turn them into manufacturing-grade cellulose, currently used to make everything from surgical masks to food packaging, has been developed.

Researchers have developed a new type of pipette that can deliver ions to individual neurons without affecting the sensitive extracellular milieu. Controlling the concentration of different ions can provide important insights into how individual brain cells are affected, and how cells work together. The pipette could also be used for treatments.

A research team develops disinfection robot combining physical wiping and UV-C sterilization.

Groundbreaking device instantly detects dangerous street drugs, offering hope for harm reduction A portable device that instantly detects illicit street drugs at very low concentrations, thereby highlighting the risks they pose. The device has the potential to address the growing global problem of people unknowingly taking drugs that have been mixed with undeclared substances, including synthetic opioids such as fentanyl and nitazenes.

Influenza viruses are among the most likely triggers of future pandemics. A research team has developed a method that can be used to study the interaction of viruses with host cells in unprecedented detail. With the help of their new development, they have also analyzed how novel influenza viruses use alternative receptors to enter target cells.

As fast fashion continues to fill wardrobes and landfills at a staggering pace, new research suggests that the future of fashion might lie not in fabric, but in pixels.

Surgical face masks help prevent the spread of airborne pathogens and therefore were ubiquitous during the COVID-19 pandemic. Now, a modified mask could also protect a wearer by detecting health conditions, including chronic kidney disease. Researchers incorporated a specialized breath sensor within the fabric of a face mask to detect metabolites associated with the disease. In initial tests, the sensor correctly identified people with the condition most of the time.

Researchers have outlined a bold new roadmap for harnessing heterogeneous catalysis to destroy per- and polyfluoroalkyl substances (PFAS), the so-called 'forever chemicals' that have contaminated water supplies worldwide.
