Cheetah-Cub: A Robot That Runs Like a Cat

Cheetah-Cub: A Robot That Runs Like a Cat

Thanks to its legs, whose design faithfully reproduces feline morphology, EPFL’s four-legged “cheetah-cub robot” has the same advantages as its model: it is small, light and fast. Still in its experimental stage, the robot will serve as a platform for research in locomotion and biomechanics.   Even though it doesn’t have a head, you can [...]

Repairing Turbines With the Help of Robots

Repairing Turbines With the Help of Robots

Compressor and turbine blades are important components in aircraft engines and gas turbines. When they become damaged, it is often cheaper to repair them than to buy replacements. Now there is a new robotassisted technique that is boosting efficiency.   The German turbomachinery sector is booming. Over the past 25 years, it has doubled its [...]

World Population Could Be Nearly 11 Billion by 2100

World Population Could Be Nearly 11 Billion by 2100

A new statistical analysis shows the world population could reach nearly 11 billion by the end of the century, according to a United Nations report issued June 13. That’s about 800 million, or about 8 percent, more than the previous projection of 10.1 billion, issued in 2011.   The projected rise is mostly due to [...]

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 [...]

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 [...]
