“Cooling without electricity or water”: DGIST develops “self-cooling film” for thermal management in AI-era electronic devices
14+ hour, 24+ min ago (186+ words) □ Professor Seong Kyun Kim’s research team achieved a major breakthrough in addressing these limitations by combining “nanocellulose,” which possesses excellent moisture storing capacity, with organic ionic molecules with robust hygroscopic properties to synthesize a novel flexible, adhesive film material. □ When…...
Joint PAPR reduction and digital post-distortion transmission framework for nonlinear OFDM systems
1+ day, 5+ hour ago (142+ words) Credit: Sai Huang, et al. Orthogonal Frequency-Division Multiplexing (OFDM) signals inherently exhibit a high Peak-to-Average Power Ratio (PAPR). This forces the Power Amplifier (PA) to operate with large input back-off, resulting in substantial energy waste and posing a serious challenge…...
Fingerprint authentication without storing fingerprints
1+ day, 19+ hour ago (692+ words) EurekAlert! Comparison between conventional store-and-compare fingerprint authentication and direct ultrasound-based authentication A research team led by Professor Junsuk Rho of the Departments of Mechanical Engineering, Chemical Engineering, Electrical Engineering, and the Graduate School of Convergence Science and Technology at POSTECH,…...
Membrane computer illustration (IMAGE)
1+ day, 20+ hour ago (46+ words) EurekAlert! A plant cell with computer circuitry integrated into its plasma membrane illustrates the “membrane computer” concept, where cell surfaces act as computational hubs that turn the external world into actionable signals. Salk Senior Illustrator Amy Cao With credit and…...
The science behind the world’s fastest autonomous racing drone
2+ day, 2+ hour ago (367+ words) video: Watch the development and the science behind the world's fastest autonomous racing drone. view more Credit: Micro Air Vehicles Lab | Delft University of Technology The TU Delft team set out to investigate how far artificial intelligence can push a…...
SwRI develops drone-detection system with event-based, neuromorphic cameras
2+ day, 5+ hour ago (109+ words) SAN ANTONIO — October 14, 2026 — Southwest Research Institute (SwRI) has developed a new tool that uses neuromorphic cameras to detect unmanned aerial system (UAS) drones. SwRI’s Hierax system pairs event-based cameras, dynamic sensing technology that mimics the power of human eyesight, with…...
Building better solar tech, a crystal at a time
2+ day, 6+ hour ago (444+ words) Perovskites, manufactured crystals used in solar cells, have long promised to boost solar power, but internal defects have blunted their potential. Now, researchers at Princeton Engineering have corrected the defects by adding a novel combination of chemicals during fabrication. The…...
SwRI unveils new products for safety-critical battery applications
3+ day, 2+ hour ago (120+ words) SAN ANTONIO — October 13, 2026 — Southwest Research Institute (SwRI) is deeply involved in the development of safety-critical battery systems. With markets requiring higher rates of charge/discharge (C-rate) to meet application demands, modern batteries are being pushed to their limits. SwRI has…...
KAIST develops transistor-based encryption that controls when information can be read
2+ day, 18+ hour ago (549+ words) Professor Kyung Min Kim’s team in the Department of Materials Science and Engineering implemented both long-term and short-term memory in a single semiconductor device Figure 1. Overview of the dual-state programmable oxide transistor (DUPOT) and concept of time-based cryptography KAIST (President…...
Can vision-language models understand unstructured road scenes under degraded sensing conditions?
2+ day, 23+ hour ago (203+ words) image: Overview of the test and evaluation framework. Scenes from unstructured roads, captured via multiple camera views, are expanded into twenty corruption types. These inputs are used to generate questions covering perception, prediction, explanation, and planning, which are then evaluated…...
