The electromagnetic spectrum we can access with current technologies is completely occupied. This means experts have to think of creative ways to meet our rocketing demands for data.
Free space optical communication will allow the same connectivity in space we already have on Earth. And this will provide benefits across a number of sectors.
Using lasers to trap and move particles changed the way we're able to study microscopic life.
Cloud Gate, 2004. Stainless steel, 1,006 x 2,012 x 1,280 cm.
Anish Kapoor made “Cloud Gate”, a giant bean-shaped mirror in Chicago. Visitors play with the light in the city and its surroundings, where our future lays.
In 1954, three scientists observed a paradox to which they gave their name: the Fermi-Pasta-Ulam recurrence. Now, fibre optics are on the way to finally providing an explanation.
It’s been 70 years of instant photography, thanks to Edwin Land, on the left.
Whether at a family gathering or in a research lab, getting access to images immediately was a game changer. And Land's innovations went far beyond the instant photo.
Could there be a future with smaller, less bulky VR headsets?

Using nanostructures on a flat piece of glass can make lenses smaller, lighter and much cheaper – while providing better image quality.
Single-pixel cameras, multi-sensor imaging and quantum technologies will change the way we take photos.
Super-black feathers on these guys are like looking into a dark cave.
Male Birds of Paradise have patches of super-black plumage that absorb 99.95 percent of light. New research identified their feathers' microscopic structures that make them look so very dark.
A new technique could help the police identify more criminals from just their footprints.

The laws of physics dictate that to pick out ever fainter objects from space and see them more sharply, we're going to need a bigger telescope. And that means we need massive mirrors.
A new invisibility cloak can hide objects using an ultrathin layer of nanoantennas that reflect off light. Are humans next?

Research into invisibility cloaks has been flourishing over the past decade yet they have still not reached the market. But that may be about to change.
Spot the fox, wolf, sheep and…cuttlefish.

Study shows how eyes that work for hunters are no use for the hunted.
Green lasers glowing within cells.
Matjaž Humar and Seok Hyun Yun
Using fluorescent dye, researchers figured out how to turn cells into lasers – with applications for cell tagging and tracking as well as medical diagnoses and therapies.
Wicked fast communication.

Your home internet connection works in one of two ways. One involves using a copper wire, probably your telephone line, to send electrical signals from the internet provider to your home and back. This…
As much as we like to think that we vote on substance – not style – studies have shown that physical appearance matters to voters.
While much of the 2014 midterm election analysis centered on the Republican takeover of the Senate, the pundits may have overlooked an important development: the end of a time when politicians looked a…

Using nanotechnology, researchers have developed a technique to increase the data storage capacity of a DVD from a measly 4.7GB to 1,000TB.
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…

The Lytro is ripe for exploitation in ways that have yet to be explored.
We’ve all been there: the photo that would rock if not for the dodgy focus, highlighting a pot plant instead of your subject’s head. Today, nine-or-so months after its launch in the US, the Lytro camera…
Small aberrations are produced by the cells of the primary visual cortex, distorting optical information even before the…
