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 throug

Did you know that a few years ago, 21 US states recorded record LOW temperatures? Now isn't it odd this wasn't widely reported in the media, I mean you would think record low temps would be newsworthy. They certainly do report record high temps.
A temporary record low is weather, not climate. Or are you saying they had years of lowest average temperatures?
You didn't really think the news media was objective, did you? The five (FIVE) corporations that control all major news media (TV, newspapers, magazines, radio) are amazingly homogeneous in their views, sorta like the way the few wireless carriers in the US are amazingly homogeneous in their service levels and pricing (they ALL overcharge for texting for example).
And they are all conservative.

As in Jeff Bridges in TRON? That's what this laser beam thing reminds me of. (but you probably mean the bifrost from Thor)
Note the subject. Light bridges are a common occurrence in many sci-fi/futuristic games.

Structures made of light are less sturdy than those made of straw, or bricks, nevertheless they are immune to being blown down with mere huffing and puffing.

Wait, I retract that. If the light is of a high enough intensity, it'd be life a force-field with enough power to burn or vaporize or plasma-ize anything that tries to come in contact with it. Yes, this mysterious 4th pigs "House of Light" would be impervious to the wolf!

You left out houses made of "sticks" [there were three little pigs], but otherwise, your analysis is spot-on! But even if they're immune from being blown down, I don't think they'd do a good job of stopping the wolf from getting in. . Wait, I retract that.

What you don't know is that aliens are all around us and that stars are really just what you described the mysterious fourth pigs house as being...just with aliens inside.
