ESA engineers are proposing a technique to enable a digital satellite radio service for European drivers – without the need to launch a single new satellite into orbit.

Commercial digital satellite radio is already a reality in the United States, using a costly set of dedicated satellites. The rival American services allow subscribing drivers to choose between numerous near-CD quality radio channels without tune-out or static.
Two parallel ESA studies have examined a lower-cost method o

Report envisions a future cyberinfrastructure that will “radically empower” the science and engineering community

The critical needs of science and rapid progress in information technology are converging to provide a unique opportunity to create and apply a sustained cyberinfrastructure that will “radically empower” scientific and engineering research and allied education, according to the National Science Foundation (NSF)’s Advisory Committee for Cyberinfrastructure. The committee

A Penn State researcher has developed a faster method for more efficient sharing of widely distributed Internet resources such as Web services, databases and high performance computers.

Jonghun Park, assistant professor in Penn State’s School of Information Sciences and Technology (IST) who has proposed the protocol, says the new technology speeds up to 10 times faster the allocation of Internet resources.

“In the near future, the demand for collaborative Internet applications wi

Museum curators and researchers who need to view historical artefacts or works of art in museums and galleries such as the Louvre, the Uffizi and London’s National Gallery, should be able to save on their plane and train fares thanks to a unique project being undertaken by computer scientists at the University of Southampton.

The project, known as SCULPTEUR, involves building an advanced database to store three-dimensional representations of museum artefacts and works of art together wi

Huge data sets examined interactively yet remotely

A surgeon in New York who wants the opinion quickly of a specialist in Los Angeles probably would send medical MRI [magnetic resonance imaging] files as e-mail attachments or make them accessible in Internet drop zones. Unfortunately for patients on operating tables, extremely large files may take a half-hour to transmit and require a very large computer ( perhaps not available ) to form images from the complicated data. Additionally,

Representatives from 14 international, national, and regional organisations from around the world meeting in Brazil have agreed to form a World Federation of Science Journalists, recognizing the increasing international nature of science communication.

The new organization is designed to bridge scientists and society worldwide by creating a network for the exchange of information, improving access to scientific and technical sources and facilitating training and education of journalists par
