World’s Blackest Material Now Comes in a Spray Can
Vantablack is now available in a spray-on form that blocks 99.8 percent of ultraviolet, visible and infrared light — enough to make an otherwise detailed 3D object appear as a flat black void. By Kacey Deamer. (Apr. 5, 2017)

New material helps record data with light
Russian physicists with their colleagues from Europe have learned to generate quasiparticles—excitons, which were fully controllable and able to record information at room temperature. These particles act as a transitional form between photons and electrons, so the researchers believe they can be used to create compact optoelectronic devices for rapid recording and processing of optical signals.

Physicists detect exotic looped trajectories of light in three-slit experiment
Physicists have performed a variation of the famous 200-year-old double-slit experiment that, for the first time, involves “exotic looped trajectories” of photons.

Plants ‘see’ underground by channelling light to their roots
Roots of many plants have light receptors, and now we may have discovered why. They seem to channel light underground using stems as fibre-optic cables. By Alice Klein.

Light: Particle or Wave?
Classically, light can be thought of in two ways: either as a particle or a wave. But what is it really? Well, the ‘observer effect’ makes that question kind of difficult to answer. So before we get too far into it, what is the observer effect?

Device can theoretically trap a light ‘bit’ for an infinite amount of time
Researchers have designed a nanoscale device that, under ideal conditions, can confine a “bit” of light (that is, light with a single precise energy value) for an infinite amount of time.

Unbounded High Dynamic Range Photography using a Modulo Camera
This paper presents a novel framework to extend the dynamic range of images called Unbounded High Dynamic Range (UHDR) photography with a modulo camera. A modulo camera could theoretically take unbounded radiance levels by keeping only the least significant bits. We show that with limited bit depth, very high radiance levels can be recovered from a single modulus image with our newly proposed unwrapping algorithm for natural images.

Humans cling to their primal fear of the dark
Your chances of being attacked, robbed, or struck by a car are no worse on a dimly lit street. And yet, like cavemen huddled around a campfire, humans are still comforted by light. By Eric Betz.

The first ever photograph of light as both a particle and wave
Light behaves both as a particle and as a wave. Since the days of Einstein, scientists have been trying to directly observe both of these aspects of light at the same time. Now, scientists at EPFL have succeeded in capturing the first-ever snapshot of this dual behavior.
