Newly published research demonstrates a novel way of generating phonon-polaritons by making electrons collide with crystal lattice structures. The discovery paves the way for cheaper, smaller long-wave infrared light sources and more efficient device cooling.

A leaping robot could have application in search and rescue, construction, even forest monitoring. But how do you design a robot to stick a landing on a branch or pipe? Biologists worked with robot designers to discover how squirrels do it, and used what they learned to design a one-legged robot with the balancing ability and leg biomechanics to correct for over- and undershooting and land successfully on a narrow perch.

Scientists have successfully established the world's longest intercontinental ultra-secure quantum satellite link, spanning 12,900 km. Using the Chinese quantum microsatellite Jinan-1, launched into low Earth orbit, this milestone marks the first-ever quantum satellite communication link established in the Southern Hemisphere.

An AI-powered robot that can prepare cups of coffee in a busy kitchen could usher in the next generation of intelligent machines, a study suggests.

A rapid prototyping platform called VIK (Voxel Invention Kit) enables makers without engineering expertise to create large-scale interactive devices using a series of reconfigurable electromechanical building blocks. These user-friendly components can be assembled using only a soldering iron and a pair of pliers.

Chemists have created a machine learning tool that can identify the chemical composition of dried salt solutions from an image with 99% accuracy. By using robotics to prepare thousands of samples and artificial intelligence to analyze their data, they created a simple, inexpensive tool that could expand possibilities for performing chemical analysis.

An AI system can tell the calorie count, fat content, and nutritional value of a meal just from a photo.

A research team has developed an artificial intelligence-powered ring equipped with micro-sonar technology that can continuously and in real time track finger-spelling in American Sign Language (ASL).

Scientists are exploring how web search engine technology might also keep the lights on, the water running and the trains moving.

Scientists have unveiled an innovative approach for synthesizing azaparacyclophanes (APCs), a class of highly advanced ring-shaped molecular structures with immense potential in material science. Their innovative Catalyst-Transfer Macrocyclization (CTM) method streamlines the production of these complex macrocycles, paving the way for more efficient and scalable applications in organic electronics, optoelectronics, and supramolecular chemistry -- such as displays, flexible solar cells and transistors.

The smart MAIJU jumpsuit offers a novel approach to at-home monitoring of infants' early motor development. The wearable device combines expertise in medicine, measuring technology and AI, enabling objective and accurate assessment of children's motor skills without the presence of researchers.

An openly available generative AI tool can interpret millions of cells in human tissues in hours, revealing new insights and allowing researchers and clinicians to ask questions about conditions such as cancer.

Physicists have measured a nuclear reaction that can occur in neutron star collisions, providing direct experimental data for a process that had previously only been theorised. The study provides new insight into how the universe's heaviest elements are forged -- and could even drive advancements in nuclear reactor physics.

Researchers have created an AI tool to accelerate the development of new disease treatments and demonstrated its potential by identifying an existing drug with the potential to prevent deadly heart failure.

Virginia Tech researchers say a true revolution in wireless technologies is only possible through endowing the system with the next generation of artificial intelligence (AI) that can think, imagine, and plan akin to humans. Doing so will allow networks to break free from traditional enablers, deliver unprecedented quality, and usher in a new phase of the AI evolution.

For decades, atomic clocks have been the pinnacle of precision timekeeping, enabling GPS navigation, cutting-edge physics research, and tests of fundamental theories. But researchers are now pushing beyond atomic transitions to something potentially even more stable: a nuclear clock.

Companies can significantly enhance their stock market performance by adopting Integrated Reporting (IR) and Combined Assurance (CA) practices, according to new research that underscores the importance of transparency and accuracy in financial reporting.

Researchers have developed a powerful AI tool, built on the same transformer architecture used by large language models like ChatGPT, to process an entire night's sleep. To date, it is one of the largest studies, analyzing 1,011,192 hours of sleep. The model, called patch foundational transformer for sleep (PFTSleep), analyzes brain waves, muscle activity, heart rate, and breathing patterns to classify sleep stages more effectively than traditional methods, streamlining sleep analysis, reducing variability, and supporting future clinical tools to detect sleep disorders and other health risks.

Engineers developed a method to grow artificial muscle tissue that twitches and flexes in multiple, coordinated directions. These tissues could be useful for building 'biohybrid' robots powered by soft, artificially grown muscle fibers.

Scientists have developed a single-cell green microalgae coated with magnetic material. This miniature robot was put to the test: would the microalgae with its magnetic coating be able to swim through narrow spaces and, additionally, in a viscous fluid that mimics those found in the human body? Would the tiny robot be able to fight its way through these difficult conditions?
