Microscopic polystyrene balls - now jet-propelled
Physicists have created an armada of self-propelled polystyrene balls about as wide as a strand of your hair. Their efforts are moving toward self-propelled nanoswimmers that could navigate narrow channels such as the human circulatory system.

The secret to mosquito water walking appears to be feathery scales a few microns across that in turn are covered with nanoscopic ribbing, forming what the physicists have dubbed (in an apparent fit of excessive prefixing) a micronanostructure.

Read moreOn a wire or in a fiber, a wave is a wave
In an experiment modeled on the classic "Young's double slit experiment" researchers have powerfully reinforced the understanding that surface plasmon polaritons move as waves and follow analogous rules.

Read moreModern redux of classic experiment illuminates nanoscience of 'plasmonics'
The science of plasmonics describes how metals can essentially transmit and manipulate light waves at length scales much smaller than their wavelengths. Now, by redoing a classic optics experiment with plasmonics, engineers have made key insights into the nature and the practical limits of this up-and-coming nanoscale information technology.
