The smallest piece of artwork ever made has finally been unveiled to the world. It's an image of the sun made from 20,000 microscopic particles of gold, and what is most unique about the creation is that it was done without the presence of an ... artist. (Source: usatoday.com ) IBM researchers are taking credit for the piece that used ultra-miniature sensors, lenses and wires inside of nanoscale circuits. The image of the sun was etched on a silicon chip "wafer" using a special technique that manipulated each gold particle which measured just 60 nanometers in diameter. In proportion, a nanometer ... (view more)

Here's a new and yet very odd tech threat: the particles emitted by your office printer. According to an Australian research team associated with the Queensland University of Technology, these tiny airborne particles, which waft outwards from laser ... printers, can cause health problems including: respiratory issues cardiovascular irritation various types of cancer Unfortunately, researchers remain uncertain exactly what chemicals within the particles directly affect the human body. However, they have some vital tips for ensuring the long-term health of workers who consistently use laser ... (view more)
