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 / 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 / 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 / Is there an AI bubble? No, but some tech companies show signs
Like past transformative technologies, from railroads and radio to the internet, artificial intelligence has attracted optimistic investors and inflated valuations, and with them speculation of a bubble market—when eager ...
Tech Xplore / New drone-compatible method detects metal corrosion beneath paint without heating
Merchant ships, coastal infrastructure and maritime facilities are often built with iron and steel, which can corrode over time despite their strength, eventually to the point of failure. With lives and goods on the line, ...
Tech Xplore / Baker's yeast helps store green hydrogen in alcohols, iron releases it
Hydrogen gas (H₂) is widely regarded as a promising clean energy source. By weight, it stores nearly three times more energy than gasoline, and its use does not directly release carbon dioxide (CO₂). Yet most H₂ is still ...
Tech Xplore / Electrified plasma heating offers a lower-carbon route to cement production
Cement is one of the most consumed materials globally, second only to water. However, the world's enormous appetite for cement also has an environmental cost: Its production generates more than a billion metric tons of carbon ...
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.
Tech Xplore / Spy-device detector users miss nearly 60% of hidden gadgets
Consumer detectors sold to help people find hidden surveillance devices are often too difficult for typical users to interpret, potentially giving a false sense of security to those most at risk such as domestic abuse survivors, ...
Tech Xplore / Fruit fly-inspired algorithm classifies odors from only a few samples
In the animal kingdom, energy conservation is essential for survival. That's why our brains have evolved to be extremely energy- and resource-efficient at storing and processing information. Since the 1980s, computational ...
