Scientists have designed an ultra-miniaturised device that could directly image single cells without the need for a microscope or make chemical fingerprint analysis possible from a smartphone.  Nanowires promise to make LEDs more colorful and solar cells more efficient, in addition to speeding up computers.  A new form of electron microscopy allows researchers to examine nanoscale tubular materials while they are "alive" and forming liquids—a first in the field.  A UCLA-led team has gained a never-before-seen view of nucleation—capturing how the atomsrearrange at 4-D atomic resolution (that is, in three dimensions of space and across time).
