University of Utah researchers have demonstrated a new method of 3D printing that avoids the leaky seams that come with the layer-by-layer process. Using a nanoscale "mask" that diffracts laser light into a holographic pattern ...

Many digital users rely on Virtual Private Networks (VPNs) to combat security threats, allowing the application to view, intercept and handle all user traffic in return for hiding identifying information from third parties. ...

Energy storage is becoming critical to grid resilience and electricity affordability because battery systems can help balance supply and demand and stabilize power.

Many experts refer to hydrogen as "the fuel of the future." It is expected to help decarbonize the global economy in two main ways: Burning it or feeding it into a fuel cell produces storable energy with no carbon emissions, ...

The amount of time young people spend playing video games is not enough to judge whether gaming is linked to cognitive difficulties. A new study of several thousand adolescents shows that gaming time and symptoms of Internet ...

Your online order arrives damaged, so you request a refund. What often follows is an artificial intelligence workflow involving multiple AI models: One model checks your request against company policy, another analyzes the ...

The future hydrogen economy may hinge on iridium, a metal so rare that only about 8 tonnes are produced worldwide each year. To help stretch the limited supply, University of Delaware researchers have developed a recycling ...

Soft grippers, which are built from flexible materials that can bend and deform, are attracting a lot of attention from robotics researchers worldwide. Unlike conventional robots made from rigid metal or plastic, soft grippers ...

Walking robots, such as quadruped robotic dogs, must be able to move safely through rough, often changing environments. Today, there are two main ways to program these walking, or legged, robots. The first is called model ...

A battery that "talks" does not use words—it communicates through data. Researchers at Kiel University have demonstrated how sensors inside a battery cell can transmit measurement data to the outside without the need for ...

Air is absolutely essential for human life, but for certain semiconductors, it is a deadly poison. The moment these materials come into contact with air, unreacted tin ions on their surface oxidize, creating defects that ...

Over the past few decades, engineers have developed various devices that can create holograms, three-dimensional (3D) or two-dimensional (2D) images produced by precisely controlling the shape and direction of traveling light ...
