Watch: An Animated Short On How We Measure The Universe | Co.Design: business + innovation + design

Ever wonder how we possibly know how far away stars and galaxies are from the earth? Obviously it involves telescopes and measurements, right? But beyond that, how does our observed data actually translate into light years? How do we know what we know?

This animation by Royal Observatory Greenwich explains the fundamental tools astronomers use to decode data from dots of light--principles like parallax and redshift. And don’t worry, nothing requires a science degree to unders... (View original article)

Laser Un-Printers Could Remove Toner Ink from Paper : TreeHugger

FeatheredTar/CC BY 2.0

Researchers at the University of Cambridge have discovered a way to use lasers to remove toner ink from paper so that it can be reused instead of being recycled or, worse, tossed in the garbage. In the future, those old TPS reports taking up space on your desk could quickly be turned into clean sheets of paper by sending them through an "un-printer."

The researchers studied 10 different laser setups ranging in strength and pulse d... (View original article)
