Suggested applications include increased efficiency in solar cells, more energy-efficient lighting and advances in quantum mechanics. No word yet on invisibility cloaks."Schubert and his coworkers have created a material with a refractive index of 1.05, which is extremely close to the refractive index of air and the lowest ever reported. Window glass, for comparison, has a refractive index of about 1.45.

Using a technique called oblique angle deposition, the researchers deposited silica nanorods at an angle of precisely 45 degrees on top of a thin film of aluminum nitride, which is a semiconducting material used in advanced light-emitting diodes (LEDs). From the side, the films look much like the cross section of a piece of lawn turf with the blades slightly flattened.
For the system to work, players at multiple levels would need to get involved. Broadcasters would need to add identifying watermarks to their broadcast, in cooperation with copyright holders, and both parties would need to register their watermarks with the system. Then, in the event that a user capped a broadcast and uploaded it online, the scanner system would eventually find it and report its location online. [...] Generally we've laughed off most watermarking solutions because they seemed like solutions in search of a problem. Now that Google has learned the hard way that content owners want to be paid when their content shows up on YouTube, we may see more of these "solutions" in the future.
Variables don't; constants aren't.
