Imagine having computer memory so dense that a cubic centimeter contains 12.8 million gigabytes of information. Imagine an iPod playing music for 100 millennia without repeating a single song or a USB thumb-drive with room ...


Physicists Store Images in Vapor

June 23, 2008 | User rating: 4.5 / 5 after 93 vote(s) | User comments: 4

Books are written on solid pieces of paper for an obvious reason: the atoms in a solid don’t move around much, keeping the words and pictures in place for centuries. Trying to store letters and images in a ...


Scientists discover water is sticky on a small scale

May 08, 2006 | User rating: 4.4 / 5 after 105 vote(s) | No comments yet

When water vapor condenses in a nano-sized space between two surfaces, the liquid behaves more like solid ice than liquid water, even at room temperature. This solidification causes water to exert such a strong ...


Discovering How to Focus on Tiniest of the Very Small
