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 / Tailored surface vibrations to improve aerodynamic performance in passenger jets
A passenger jet soars across the sky at 640 mph (1,030 kilometers per hour), its wings pummeled with wind and boundary-layer turbulence, challenging the plane's operation and efficiency. Advancing research from Mahmoud I. ...
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 ...
Tech Xplore / Smartphone navigation app guides blind and low-vision users around obstacles
For people who are blind or have low vision, moving around independently is a daily challenge. Harvard researchers have developed a new tool that could help people navigate more quickly and safely with nothing more than a ...
Tech Xplore / Green methanol from thin air? Model finds water and CO₂ could be captured together
Persistent heat waves and below-average rainfall in spring and summer 2026 are causing drought conditions, falling groundwater levels and low river levels, including in the Rhine in Germany and elsewhere across Europe. At ...
Tech Xplore / Scalable semitransparent organic PV modules could turn windows into power generators
Organic solar modules score points for their flexibility, transparency, and a particularly good environmental footprint. Wavelength-dependent transparency, in particular, is a major strength of organic photovoltaics. Researchers ...
Tech Xplore / Concrete's natural absorption of CO₂ does little to offset emissions from cement production, study finds
Concrete slowly absorbs small amounts of carbon dioxide from the air over its lifetime, a natural process sometimes proposed as a solution to the cement industry's heavy carbon footprint. But a new UCLA-led study finds that ...
