Korean researchers have confirmed that underground wireless communication is possible, moving beyond the terrestrial wireless communication they have primarily focused on until now. This opened up a new wireless channel for confirming the survival of buried people in the event of a collapse of an underground facility such as a... Read more

A team of researchers co-led by the University of California San Diego, University of Michigan, and the French National Center for Scientific Research (CNRS) at Laboratory of Acoustics of Le Mans University has demonstrated a new way to remotely control how a material behaves—using sound. The findings could lead to... Read more

Thermal batteries can efficiently store energy as heat. But building them requires a carefully designed system with materials that can withstand cycles of extremely high temperatures, without succumbing to problems like corrosion, thermal expansion, and structural fatigue.... Read more

Cutting patterns into elastic materials allows you to unfold those materials into new shapes, and researchers have now demonstrated the ability to control the sequence in which that unfolding happens by magnetizing the materials. The work represents a fundamental advance in our understanding of metamaterial behavior and has also demonstrated... Read more

NUS researchers have developed a platform that lets lab-grown muscle tissues train themselves to record-breaking strength, with no external stimulation required. By mechanically coupling two muscle tissues so they continuously pull against each other, their own natural contractions become a round-the-clock workout. The resulting muscles powered OstraBot, an ostraciiform (a... Read more

A team of international researchers have developed a breakthrough way to observe what is happening inside electronic chips while they are operating—without touching them, taking them apart, or switching them off. The new technique uses terahertz waves, a safe and non-ionizing form of electromagnetic radiation, to detect tiny movements of... Read more

Projection mapping is widely known as a lighting technique that overlays images onto buildings or objects to create visual effects. In fields such as extended reality (XR) and vision science, however, researchers have suggested that projection could go beyond simple overlays, potentially allowing the color, pattern, or even the perceived...

Researchers from IMDEA Materials Institute, in collaboration with China's Nanjing and Huazhong Universities, have developed a new acoustic metamaterial capable of transmitting complex sound signals directly between water and air. The advance, reported in the paper "High-dimensional multiplexed metamaterial for cross-media all-sound communication," introduces a novel approach that could significantly... Read more

The pixels in phone screens and other OLED displays appear to provide a uniform glow, but a team of University of Michigan Engineering researchers has discovered the light actually originates from nanoscale hotspots, some of which flicker. This might be hurting device lifespans.... Read more

What if electronic circuits could be created simply by drawing lines with a pencil on paper or leaves—and then immediately applied to soft robots or skin-attached health monitoring devices? Korean researchers have developed an electronic materials technology that forms electrically conductive liquid metal in a fine powder form, allowing circuits... Read more

A research team led by Professor Jae Eun Jang and Dr. Goeun Pyo from the Department of Electrical Engineering and Computer Science at DGIST has developed "dual-modulated vertically stacked transistors" that operate stably without current leakage even in two-dimensional nanoscale channel structures. A study on this work is published in... Read more

Among the biggest complaints inhibiting growth in the electric vehicle market is the limited lifespan and range of lithium-ion batteries. Consumers fear being stranded far from home with long wait times at recharging stations. A promising area of research has focused on layer-structured metal oxide cathodes. Specifically, a material known... Read more

Do you want to know how much noise there is on a construction site? You want to measure the sound of the excavator or the hammer drill, but you don't want to measure seagulls, traffic noise or a helicopter flying by. Now a new sound measurement service can do just... Read more

Cobalt and nickel are vital components for batteries, superalloys and catalysts, used in technologies ranging from smartphones to jet engines. But when it comes to recycling, they are notoriously difficult to separate because they are chemically nearly identical. To solve this, a team led by scientists at Johns Hopkins University...

More than 500 years ago, Michelangelo spent four years painting "The Creation of Adam" on the ceiling of the Sistine Chapel, struggling with paint dripping onto his face. He described the process as "closer to torture than painting." Now, researchers at KAIST have developed a technology that can effectively "hold... Read more
