Researchers replicate Doctor Who's famous sonic screwdriver (w/video)

For fans of the hit series Doctor Who, the Sonic Screwdriver will be a familiar device. But now an international team of EU-funded researchers has taken equipment designed for magnetic resonance imaging (MRI)-guided focused ultrasound surgery and demonstrated a real Sonic Screwdriver, lifting and spinning a free-floating 10 cm-diameter rubber disk with an ultrasound beam.

Self-assembling nano boxes open the door to "smart" particles

While it is relatively straightforward to build a box on the macroscale, it is much more challenging at smaller micro- and nanometer length scales. At those sizes, three-dimensional (3-D) structures are too small to be assembled by any machine and they must be guided to assemble on their own. And now, research has led to a breakthrough showing that higher order polyhedra can indeed fold up and assemble themselves.

Compressed sensing allows super-resolution microscopy imaging of live cell structures

Researchers from the Georgia Institute of Technology and University of California San Francisco have advanced scientists' ability to view a clear picture of a single cellular structure in motion. By identifying molecules using compressed sensing, this new method provides needed spatial resolution plus a faster temporal resolution than previously possible.
