    First unveiled in 2007, Hitachi's adorable little service robot EMIEW 2 has been gradually improving over the years. Standing 80 centimeters tall and weighing 14 kilograms, the robot is rather unusual in that it moves on a combination of legs and wheels, a system that works a bit like...

  • Nanometer-Scale Magnet Makes Tiny, Powerful MRI

    spectrum.ieee.org 22 Apr '14, 6pm

    The trend in making more powerful magnetic resonance imagining (MRI) devices has been to produce larger magnets. A European consortium, for example, is building what will be the most powerful MRI , capable of producing a field of 11.75 teslas using a superconducting magnet strong enou...

    The Wizardry of Id

    spectrum.ieee.org 22 Apr '14, 7am

    The new graphics cards were known as Enhanced Graphics Adapter (EGA) cards. They had more on-board video memory than the earlier Color Graphics Adapter (CGA) cards and could display 16 colors at once, instead of four. For Carmack, the extra memory had two important consequences. First...
