Silicon-Based Nanoparticles Could Make LEDs Cheaper, Greener to Produce

Silicon-Based Nanoparticles Could Make LEDs Cheaper, Greener to Produce

Light-emitting diodes, or LEDs, are the most efficient and environmentally friendly light bulbs on the market. But they come at a higher up-front price than other bulbs, especially the ones with warmer and more appealing hues.   Researchers at the University of Washington have created a material they say would make LED bulbs cheaper and [...]

Gamers Capture More Information Faster for Visual Decision-Making

Gamers Capture More Information Faster for Visual Decision-Making

Hours spent at the video gaming console not only train a player’s hands to work the buttons on the controller, they probably also train the brain to make better and faster use of visual input, according to Duke University researchers.   “Gamers see the world differently,” said Greg Appelbaum, an assistant professor of psychiatry in [...]

Intelligent Door Seal Prevents Poor Air Quality

Intelligent Door Seal Prevents Poor Air Quality

For a long time, heat insulation was en vogue – and nearly no one was concerned about poor indoor air quality. And yet excess CO2 hampers concentration. Now, researchers have come up with an intelligent door seal system.   Heated debates and no agreement in sight: the eight employees sitting in a small conference room [...]

When Will My Computer Understand Me?

When Will My Computer Understand Me?

It’s not hard to tell the difference between the “charge” of a battery and criminal “charges.” But for computers, distinguishing between the various meanings of a word is difficult. For more than 50 years, linguists and computer scientists have tried to get computers to understand human language by programming semantics as software. Driven initially by [...]

Firefighting Robot Paints 3-D Thermal Imaging Picture for Rescuers

Firefighting Robot Paints 3-D Thermal Imaging Picture for Rescuers

Engineers in the Coordinated Robotics Lab at the University of California, San Diego, have developed new image processing techniques for rapid exploration and characterization of structural fires by small Segway-like robotic vehicles.   A sophisticated on-board software system takes the thermal data recorded by the robot’s small infrared camera and maps it onto a 3D [...]

Wi-Fi Signals Enable Gesture Recognition Throughout Entire Home

Forget to turn off the lights before leaving the apartment? No problem. Just raise your hand, finger-swipe the air, and your lights will power down. Want to change the song playing on your music system in the other room? Move your hand to the right and flip through the songs.   University of Washington computer [...]

Building 3-D Fractals On a Nano Scale

Building 3-D Fractals On a Nano Scale

It starts with one 3D structure with eight planes, an octahedron. This repeats itself to smaller octahedra: 625 after just four steps. At every corner of a new octahedron, a successive octahedron is formed. A truly fascinating 3D fractal ‘building’ is formed on the micro and nano scale. It can be used for high performance [...]

Artificial Magnetic Monopoles Discovered

Artificial Magnetic Monopoles Discovered

A team of researchers from Cologne, Munich and Dresden have managed to create artificial magnetic monopoles. To do this, the scientists merged tiny magnetic whirls, so-called skyrmions. At the point of merging, the physicists were able to create a monopole, which has similar characteristics to a fundamental particle postulated by Paul Dirac in 1931. In [...]

Why Animals Compare the Present With the Past

Why Animals Compare the Present With the Past

Humans, like other animals, compare things. We care not only how well off we are, but whether we are better or worse off than others around us, or than we were last year. New research by scientists at the University of Bristol shows that such comparisons can give individuals an evolutionary advantage.   According to [...]

New Mathematical Model Links Space-Time Theories

Researchers at the University of Southampton have taken a significant step in a project to unravel the secrets of the structure of our Universe.   Professor Kostas Skenderis, Chair in Mathematical Physics at the University, comments: “One of the main recent advances in theoretical physics is the holographic principle. According to this idea, our Universe [...]
