The International Center for Advanced Internet Research (iCAIR) at Northwestern University and Path1 Network Technologies, Inc. have demonstrated an innovative capability for global, high-quality, high-performance digital video at the recent international iGrid2002 Conference in Amsterdam.
The biennial iGrid (International Grid) event is dedicated to showcasing leading-edge applications enabled by globally high-performance networks. This experiment demonstrated high-performance, end-to-end, real-time broadcast-quality video transported uncompressed from the StarLight facility in Chicago to SARA Reken- en Netwerkdiensten, in Amsterdam, a Dutch national expertise centre in the field of High-Performance Computing and High-Performance Networking.
The iGrid2002 conference focused on e-science, Grid and Virtual Laboratory applications enabled by high-performance global networks. iGrid presents the latest developments in these areas. World-wide virtual laboratory applications based on global high-performance optical networks are crucial to a wide-range of emerging science disciplines as well as to many industries. As part of a prototype global virtual laboratory demonstration, this project showed the potential for applications having access to significant amounts of bandwidth, allowing transmitting multiple simultaneous streams of uncompressed digital video at 270 Mbps (600 Mbps with Forward Error Correction).

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
