When a major disaster--man-made or natural--takes down the phone system, who ya gonna call? No one, cause the phones dead, right? Not if youre using a novel emergency communications system under development by the Maryland start-up TeleContinuity Inc. With initial support from the National Institute of Standards and Technologys Advanced Technology Program (ATP), TeleContinuity is creating a "survivable" emergency telephone system back-up network that keeps individuals, companies and government agencies in touch during disasters by seamlessly merging conventional phone lines and the Internet.
Telecontinuitys system represents a shift from traditional disaster recovery and business continuity solutions that historically have focused on location-based backup facilities and centralized telecom infrastructures.
The terrorist attacks of Sept. 11, 2001, severely disrupted phone service at the attack sites, particularly in New York, where the collapse of the World Trade Center damaged a major local phone central office. Days and even weeks later, many companies and individuals were still without phone service. During this time, however, Internet links, utilizing different lines and network architectures, operated continuously. TeleContinuitys founders realized that short-term, emergency phone service could be activated quickly, on any scale, by cross-linking surviving phone system links and Internet links as necessary, a technique they called "shoelacing."
The company says its initial version of the software for such an emergency system is designed to reroute a users phone service within minutes of a major telephone outage by delivering the call to a remote phone, cellphone or even a computer or PDA. By the end of the ATP project in the Spring of 2005, the company plans to develop an enhanced version of the software that allows administrators and users to monitor and control networks in an emergency with advanced Web-based controls. Ultimately, commercialization of the technology will require a network of hundreds of nodes that can quickly lace together phone and data network lines regardless of where in the system an outage occurs.

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...
