Researchers find access to new fluorescent materials      (via sciencedaily.com) 

Fluorescence is a fascinating natural phenomenon. It is based on the fact that certain materials can absorb light of a certain wavelength and then emit light of a different wavelength. Fluorescent materials play an important role in our everyday lives, for example in modern screens. Due to the high demand for applications, science is constantly striving to produce new and easily accessible molecules with high fluorescence efficiency.

Hotter than infinity: Light pulses can behave like an exotic gas      (via sciencedaily.com) 

In our modern society huge amounts of data are transmitted every day, mainly as short optical pulses propagating through glass fibers. With the steadily increasing density of such optical signals, their interaction grows, which can lead to data loss. Physicists are now investigating how to control large numbers of optical pulses as precisely as possible to reduce the effect of such interactions. To this end they have monitored an ensemble of optical pulses as they propagated through an optical fiber and have found that it follows fixed rules -- albeit mainly those of thermodynamics.
