Update: After abnormally high pressures were detected inside the Falcon 9's center engine, this morning's launch was aborted at the last second. The next available launch window is this Tuesday.

Tomorrow morning, whether they realize it or not, Americans will likely wake up to a new era. Though nothing will be outwardly different, a fundamental shift in the nature of spaceflight will commence during the we...

3D computer graphics (in contrast to 2D computer graphics) are graphics that utilize a three-dimensional representation of geometric data that is stored in the computer for the purposes of performing calculations and rendering 2D images.

Such images may be for later display or for real-time viewing.

Despite these differences, 3D computer graphics rely on many of the same algorithms as 2D computer vector graphics in the wire frame model and 2D computer raster graphics in the final rendere...

The first purely silicon oxide-based 'Resistive RAM' memory chip that can operate in ambient conditions -- opening up the possibility of new super-fast memory has been developed by researchers at UCL.

Resistive RAM (or 'ReRAM') memory chips are based on materials, most often oxides of metals, whose electrical resistance changes when a voltage is applied -- and they "remember" this change even when the power is turned off.

ReRAM chips promise significantly greater memory storage than curr...
