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.

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.
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.
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.
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.
Study shows how eyes that work for hunters are no use for the hunted.
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.
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…
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…
The concept of “digital metamaterials” – a simple way of designing metamaterials with bizarre optical properties that could hasten the development of devices such as invisibility cloaks and superlenses…
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…
University of California, Riverside, scientists have added ionic liquid to single-walled carbon nanotubes and modified the…
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…
For the first time ever, a beam of light has been bent around an object on a two-dimensional metal surface. The light beam…
