Toward X-ray movies
Low-power tabletop source of ultrashort electron beams could replace car-size laboratory devices. [caption id="attachment_10653" align="alignnone" width="639"] This illustration shows a miniature electron gun driven by terahertz radiation. A UV pulse (blue) back-illuminates the gun photocathode,…
Answering a longstanding question: Why is the surface…
A team of Hokkaido University scientists has unraveled a 150-year-old mystery surrounding the surface melting of ice crystals in subzero environments by using an advanced optical microscope. [caption id="attachment_10645" align="alignnone" width="965"] Figures illustrating the process…
A new system to detect spinal deformity
Hokkaido University researchers have developed a symmetry-recognition system for the surface of the human back that can three-dimensionally detect the early stages of idiopathic scoliosis, a type of spinal deformity, without the help of a…
