Taking up the sci-fi staple of "tractor beams," scientists have developed a way to use light to grab and move minuscule particles on a microchip. The research could lead to fine-grained biological sensors and other precisely built nanoscale devices.
That is really cool.

Lang and Appleyard proved their technique by getting 16 live E. coli cells to spell out "MIT" on a chip.
