Global warming warning

"Global warming - through a combination of melting glaciers, disappearing ice sheets and warmer waters expanding - is expected to cause oceans to rise by one meter, or about 39 inches. It will happen regardless of any future actions to curb greenhouse gases, several leading scientists say. And it will reshape the nation."

Artificial boy

"At 17 inches tall and 6 pounds, the artificial Zeno is the culmination of five years of work by Hanson and a small group of engineers, designers and programmers at his company, Hanson Robotics. They believe there's an emerging business in the design and sale of lifelike robotic companions, or social robots."

Nanoscale printing: 100,000 dpi printing

"With the PDMS mold loaded, it was a simple matter to "print" the gold by transferring the pattern to a surface that the particles adhered to. The authors could readily print wires as thin as 60nm across, or ordered grids of individual gold clusters. The image of the sun at left is about 50μm across and printed at a resolution of 100,000 dpi."

TeraDisc "DVD" Terabyte storage

"They use 200 5GB layers, each one only five microns apart. Prototypes have already been made to store up to 800GB of data and Mempile says it will crack the 1TB barrier before moving on to build 5TB blue laser disks. Look out for these in 2010."

Rendering for an Interactive 360º Light Field Display

"We describe a set of rendering techniques for an autostereoscopic light field display able to present interactive 3D graphics to multiple simultaneous viewers 360 degrees around the display. The display consists of a high-speed video projector, a spinning mirror covered by a holographic diffuser, and FPGA circuitry to decode specially rendered DVI video signals. The display uses a standard programmable graphics card to render over 5,000 images per second of interactive 3D graphics, projecting 360-degree views with 1.25 degree separation up to 20 updates per second. We describe the system's projection geometry and its calibration process, and we present a multiple-center-of-projection rendering technique for creating perspective-correct images from arbitrary viewpoints around the display. Our projection technique allows correct vertical perspective and parallax to be rendered for any height and distance when these parameters are known, and we demonstrate this effect with interactive raster graphics using a tracking system to measure the viewer's height and distance. We further apply our projection technique to the display of photographed light fields with accurate horizontal and vertical parallax. We conclude with a discussion of the display's visual accommodation performance and discuss techniques for displaying color imagery."
