Tech Xplore / Using light to distinguish real from fake with hard-to-replicate 'artificial fingerprints'
Shine a light, and the real can be distinguished from the fake. KAIST researchers have developed a security technology that uses unique artificial fingerprints created by the random assembly of nanoparticles. Although extremely ...
Tech Xplore / AI prevents unstable material designs, cutting costs for chip and cooling applications
Today, anyone with a large enough artificial intelligence model can generate millions of new material designs in minutes. Unfortunately, that hasn't led to a huge leap in the number of new materials being used to improve ...
Tech Xplore / Amoeba-inspired method could enable energy-efficient hardware for complex optimization
Combinatorial optimization problems are ubiquitous, underpinning decision-making in a wide range of fields, including logistics, transportation, communication networks, drug discovery and materials science. However, these ...
Tech Xplore / Tri-layer electrolyte improves safety and lifespan of lithium-metal batteries
Lithium metal batteries (LMBs) that use pure lithium (Li) for their negative electrodes are attracting significant attention because of their extremely high theoretical capacity. However, their practical applications are ...
Tech Xplore / Vertical microrods boost electricity generation from evaporation by accelerating ion flow
Evaporation, the process by which water becomes vapor and disperses into the environment, draws heat from its surroundings. This heat, also known as atmospheric thermal energy, is abundant but diffuse, making it difficult ...
Tech Xplore / A Chinese humanoid robot sets a new 100-meter sprint record at Beijing Games
A Chinese humanoid robot set a new 100-meter sprint record of 8.86 seconds in Beijing on Tuesday, beating its robot competitors—and the fastest recorded human time.
Tech Xplore / Major security weaknesses found in leading open-weight LLMs
Safety protections built into some of the world's most widely used artificial intelligence (AI) models can be stripped away with alarming ease, according to a new international study.
Tech Xplore / Erasable semiconductor is programmed with light
Researchers at Princeton Engineering have created a semiconductor with unique properties: It is just a few molecules thick and can repeatedly change its properties in response to light. This is a step toward building more ...
Tech Xplore / Information encoded in a beam of light can survive real-world atmospheric turbulence
Researchers at the University of the Witwatersrand (Wits) and the University of Bordeaux in France have demonstrated a new way to send information through the atmosphere without correcting for the distortions that normally ...
Tech Xplore / Who does AI consider an expert? New benchmark shows bias across 22 LLMs
AI chatbots powered by large language models (LLMs) are widely used as recommender systems. While accelerating access to information, AI can also give factually incorrect responses or propagate societal biases.
Tech Xplore / Purple fabric beats the heat, reflecting 87.6% of sunlight and cooling simulated skin
A new purple cooling fabric developed by Chinese and Australian researchers could help people stay cooler during scorching summer days without having to resort to wearing white.
Tech Xplore / Attackers bypass Windows security without physical access
Experts have shown that the most powerful security defenses in Windows 11 can be dismantled by an attacker who never touches the target computer.
