Measuring nanoscale features with fractions of light

National Institute of Standards and Technology (NIST) researchers are seeing the light, but in an altogether different way. And how they are doing it just might be the semiconductor industry's ticket for extending its use ...

Driving metabolic pathways on with sunlight

Most life forms are directly or indirectly dependent on photosynthesis. The question is, can we exploit sunlight more broadly than in carbohydrate production, making it effectively a synthetic biology part? As an answer to ...

Using optical fiber to generate a two-micron laser

Lasers with a wavelength of two microns could move the boundaries of surgery and molecule detection. Researchers at EPFL have managed to generate such lasers using a simple and inexpensive method.

Pyramid scheme for brighter organic LEDs

The most common kind of light bulb in the United States—the incandescent—is only about 5 percent efficient. The phosphorescent organic light-emitting diode, on the other hand, makes light out of 100 percent of the electricity ...

Twisting the light away using ultrasmall holes

A new study shows that light transmitted through apertures smaller than the wavelength of light go through a radical change, splitting into two symmetrical counter-rotating polarisations.

XMM-Newton reveals cosmic collision in the Bullet Group

(Phys.org) —Despite the large distances between them, galaxies rarely exist in isolation. They are mostly found in large assemblies known as groups and clusters. Groups are the smallest gatherings, containing 50 or so galaxies ...
