NIST Therapy for Ultraviolet Laser Beams: Hydrogen-treated Fibers

Micrograph of an optical fiber that has been infused with hydrogen and cured with ultraviolet light (here shown transmitting violet laser light.) Fibers treated this way can transmit stable, high-power ultraviolet laser light for long periods of time, resisting the damage usually caused by UV light. The diameter of the pattern of air holes surrounding the core is 62.5 micrometers

Nuclear magnetic resonance experiments using Earth's magnetic field

Earth's magnetic field, a familiar directional indicator over long distances, is routinely probed in applications ranging from geology to archaeology. Now it has provided the basis for a technique which might, one day, be used to characterize the chemical composition of fluid mixtures in their native environments. Researchers have carried out nuclear magnetic resonance experiments using an ultra-low magnetic field comparable to Earth's magnetic field

Microchip reveals how tumor cells transition to invasion

A microscopic obstacle course of carefully spaced pillars enables researchers to observe cancer cells directly as they break away from a tumor mass and move more rapidly across the microchip. The device could be useful for testing cancer drugs and further research on the mechanics of metastasis


3-D Printing Builds Up Architecture

In May 2014, a private company in China, WinSun, printed 10 full-size houses using 3-D printers in the space of a day. The process utilized quick-drying cement and construction water to build the walls layer-by-layer.
