NASA & NOAA set to launch new environmental satellite

NASA is set to launch the new National Oceanic and Atmospheric Administration (NOAA) Polar-orbiting Operational Environmental Satellite (POES), another critical link in the development of a global Earth-observation program.

The spacecraft, NOAA-N, will lift off at 6:22 a.m. EDT, May 11, 2005, from Vandenberg Air Force Base, Calif. “The NOAA-N satellite is key to establishing a strong Global Earth Observation System of Systems, because it will strengthen our understanding about

Newly discovered genetic disease sheds light on body’s water balance

Two infant boys whose bodies were overloaded with excess fluid have led UCSF pediatricians to the discovery of a new genetic disease. In the process, they have discovered a rare type of mutation where different substitutions in a single amino acid cause two different, opposite genetic disorders.

The new disorder, called Nephrogenic Syndrome of Inappropriate Antidiuresis (NSIAD), is described in the May 5 issue of The New England Journal of Medicine. “This discovery gives bett

New tool reveals secrets of migrating cells

Two-photon imaging gives real-time video of cells in living tissue

Biologists have a new tool to track and videotape cells moving about inside living tissue. Called two-photon laser-scanning microscopy, it has revealed, for example, the dramatic difference between the random wanderings of immature T cells and the goal-oriented, beeline movement of activated T cells.

“This is the first time anybody has quantitated four-dimensional data – spatial and time data – to get a p

Europe’s first interactive system bringing GRID technology to the final user

Ever since the internet was created, it has developed and advanced as new services have been introduced that have made it easier to access and send data between remote computers. Electronic mail and the easy-to-use interactive interface known as the World Wide Web are just two of the most important services that have helped to make the internet as popular as it is today. GRID technology, one of the latest systems that has been developed for linking computing resources, connects hundreds of la

Traces Of The Vitim Meteoroid

In 2002-2003, three expeditions involving specialists of the Institutes of Geochemistry, of Solar-Terrestrial Geophysics, and of the Earth’s Crust, Siberian Branch, Russian Academy of Sciences (Irkutsk) looked for traces of meteoroid that had fallen down in the north-east of the Irkutsk Province, in the Mamsko-Chuisk region. None of the expeditions found either craters or meteoroid fragments. Only fallen trees and minor particles of meteorite substance mark the direction of celestial body fa

Picture this – automatic image categorisation

Creating, storing and transmitting visual images has become increasingly easy. Yet the same problem always arises – how to categorise or classify visual images automatically without using external metadata or image thumbnails? There now may be an answer.

Researchers in the IST project LAVA have developed a method of automatically categorising the content of digital images, providing an effective means of storing and retrieving digital image content without having to rely
