Laser light at useful wavelengths from semiconductor nanowires: Nanowire lasers could work with silicon chips, optical fibers, even living cells
TUM researchers have demonstrated that semiconductor nanowires like the one shown here can act both as lasers, generating coherent pulses of light, and as waveguides, similar to optical fibers. Because these nanowire lasers emit light at technologically useful wavelengths, can be grown on silicon substrates, and operate at room temperature, they have potential for applications in computing,

NASA's Cassini Spacecraft Obtains Best Views of Saturn Hexagon
This colorful view from NASA's Cassini mission is the highest-resolution view of the unique six-sided jet stream at Saturn's north pole known as "the hexagon." This movie, made from images obtained by Cassini's imaging cameras, is the first to show the hexagon in color filters, and the first movie to show a complete view from the north pole down to about 70 degrees north latitude.
