An international research team has reported an artificial nociceptor system that captures the temperature-dependent threshold modulation of biological nociceptors. Published in Advanced Functional Materials under the title "Temperature-Modulated Threshold Response in a Volatile Memristor: Toward a Biomimetic Polymodal Nociceptive System," the study was led by Professor Hee-Dong Kim of Sejong...

Wood laminates are used in many different ways, for example, in the manufacture of skis and snowboards or in components for vehicle interiors. However, their weight advantages for lightweight construction also have disadvantages. They are significantly less resilient perpendicular to the grain and when force is applied perpendicular to the... Read more

An optical principle discovered more than a century ago may soon find new applications in such areas as monitoring atmospheric turbulence, tracking airborne objects, and mapping the environment, thanks to researchers at the Georgia Tech Research Institute (GTRI).... Read more

Created from noise-resistant, conductive threads, a high-tech new smart fabric could find uses in health monitoring, sports performance and rehabilitation. The work is published in the journal Science Advances.... Read more

Researchers have developed a holographic data storage approach that stores and retrieves information in three dimensions by combining three properties of light—amplitude, phase and polarization. By allowing more data to be stored in the same space, the new approach could help advance efforts to meet the growing global demand for... Read more

In the fight against climate change, solar power is a promising alternative to fossil fuels. Every second, Earth receives an enormous amount of energy from the sun. Yet solar cells capture only a fraction of it, constrained by a "physical ceiling" that seemed impossible to break.... Read more

The next time you're scrolling on your phone, take a moment to appreciate the feat: The seemingly mundane act is possible thanks to the coordination of 34 muscles, 27 joints, and over 100 tendons and ligaments in your hand. Indeed, our hands are the most nimble parts of our bodies.... Read more

The state of Kentucky produces 95% of the world's bourbon, and all that bourbon leaves behind an enormous amount of waste grain, called stillage. Now, researchers at the University of Kentucky have developed a process to transform that stillage into electrodes. With the bourbon byproduct electrodes, they created supercapacitors that...

Swarms of pico-satellites could work together as a single large antenna for direct-to-smartphone communications, as reported by researchers from Japan. Instead of relying on a single large satellite with a phased-array antenna, the team showed that pico-satellites orbiting Earth in formation could each carry individual phased-array elements and be synchronized...

Imagine a world where you could change the designs you see on bags, shirts, and walls whenever you want. Typical clothes would become customizable fashion pieces, while your humble abode could turn into a smart home. That's the vision of scientists like MIT electrical engineering and computer science Ph.D. student... Read more

A new sustainable approach to energy harvesting could transform how wasted heat is turned into electricity, thanks to a breakthrough in low-cost, flexible materials developed by researchers at the University of Surrey's Advanced Technology Institute (ATI).... Read more

From smartphones to large-scale AI servers, most digital information in modern society is stored in NAND flash memory. KAIST researchers have developed an innovative technology that can overcome the limitations of next-generation semiconductors, where more data must be stored in smaller spaces. This advancement is expected to serve as a... Read more

Developing robust water-repellent textiles is critical for outdoor, protective, and industrial applications. However, achieving long-lasting water repellency under mechanical stress has been a major challenge.... Read more

For 150 years, Major League Baseball (MLB) players and fans have accepted that an umpire missing a few balls and strikes is just part of the game. But this spring, MLB is rolling out an artificial intelligence-augmented camera system that will provide a second opinion for players to tap if... Read more

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
