The butterfly effect: optical nanotechnology takes flight

When scientists look for keys to unlock problems such as quantum teleportation or faster internet speeds, answers can sometimes be found in the natural world. Controlling light at the nanoscale is necessary…
Using nanotechnology, researchers have developed a technique to increase the data storage capacity of a DVD from a measly 4.7GB to 1,000TB. Nature Communications

More data storage? Here’s how to fit 1,000 terabytes on a DVD

We live in a world where digital information is exploding. Some 90% of the world’s data was generated in the past two years. The obvious question is: how can we store it all? In Nature Communications today…
