Web “widgets” are small application programs designed to be run inside Web pages. The NIST time widget, created by engineer Andrew Novick, can be used on any Web page. “The widget code tells your browser to go out and grab NIST time content and post it to your page,” Novick explains, “It synchronizes with NIST’s atomic clock in Boulder, Colo., every 10 minutes, thereby guaranteeing its accuracy.”
The widget checks the viewer’s computer to determine which time zone it should display as the default. To add the NIST time widget to your Web page or blog go to www.time.gov/widget/ and copy the code. The code requires Adobe Flash Player to run. A non-Flash version (using HTML5) is under development that will enable the widget to be viewed on additional mobile devices. Also, smaller configurations in multiple shapes, sizes and formats will be available in the months ahead.
NIST’s Boulder Laboratories is the home of the most accurate clock in the world, the NIST F-1 Cesium Fountain clock. It uses transitions in Cesium 133 atoms to measure time to an accuracy of about 1 second in 100 million years.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
