Scientists track your carbon footprint, step by step
If you're driving your SUV to the farmers market to buy local asparagus and thinking you're making a difference for the planet, - not so fast. You're focused on a detail and ignoring the gas-hogging elephant in the room.
LEDs on silicon can reduce production costs
A new manufacturing technology is expected to greatly reduce the cost of light-emitting diodes (LEDs) in the future. For the first time ever, researchers at the Siemens subsidiary Osram Opto Semiconductors ...
Mini-projector for smartphones
Their very small displays sometimes make smartphones diffi cult to operate. In the future, a projector will help: if the cell phone is standing on a table, for instance, it can project a large-format display ...
Electrical engineers develop LED 'Magic Wands'
Engineers from the University of Bristol have developed illuminating magic wands that work by picking up radio signals from mobile devices. The wands, to be showcased on BBCs Bang Goes the ...
Virtual blue skies brighten the office of the future
There is light at hand for those who toil away in a poorly-lit office. Scientists at the CeBIT high-tech fair have developed a system that gives the feeling of working outside under blue skies.
