Building New Materials With Light 27
ckwu writes "Since the 1970s, physicists have used laser beams to trap and study small objects, from cells down to individual atoms. Now, electrical engineers at the University of Southern California have developed a simple optical system that assembles hundreds of nanoparticles into two-dimensional structures using a single laser beam and a silicon photonic crystal. This compact optical trap fits on a small chip and could eventually help researchers make materials for new types of sensors, optical devices, and chemical filters."

For those with ESL, advancing means to move forward. Grow means to get bigger. BACK IN 2009, the glacier started to melt fast enough that it started advancing on a cushion of meltwater toward Gilbert Point.
Along with issues like this, the global seawater high tide line is rising annually at a measurable level, and there will soon be a permanent route through the arctic ocean. This is all beside what's happening in Greenland, where the ice cap has melted enough that the island is actually rising out of the ocean (due to less mass pushing it down into the water).
None of this is breaking news; the information has been around for years. The spinning is somewhat new however, and goes both directions.
So please; stop the spin and get back to taking the frosty on other topics. This one's so old that even BSD declares it's dead.
