The Sagittarius dwarf galaxy is our nearest neighbor. Yet it has been discovered only recently, in 1994, being hidden by the stars and dust in our own Galaxy, the Milky Way. It is however possible today to better know this companion galaxy, thanks to variable stars, the RR Lyrae, in which Sgr-dw is particularly rich. In a recent paper, Patrick Cseresnjes, from Paris Observatory, shows for the first time that Sgr-dw is not typical of other satellites of the Milky Way, but reveals instead striking simi

France launches in Valenciennes a 6,4 million euro research program on transport safety. It reinforces the international position of Nord-Pas de Calais and the University of Valenciennes.

The scientific council of the New Research Action “Safety in Transport Systems”, which came together at the University of Valenciennes and Hainaut-Cambrésis on the 31st of January 2002, has just validated and launched a program composed of 7 projects stretched out until 2006. 6,4 million euros will b

More effective vaccines will be developed as a result of research at the University of Dundee which is harnessing the skills of special cells in the body`s immune response process.

The Medical Research Council has awarded Professor Colin Watts and his colleagues £1.2 million to fund work on key cells in our immune system called dendritic cells. Colin is Professor of Immunology in the School of Life Sciences.

Although immunologists have known about dendritic cells for many years thei

During the night of 28 February/1 March, Envisat, ESA’s most powerful and sophisticated Earth observation satellite, will be launched by an Ariane 5 rocket from Europe’s spaceport in Kourou at 22:07 hrs Kourou time (02:07 hrs CET).

Built by a consortium of 50 companies led by Astrium, Envisat is the successor to ESA’s ERS satellites. With an array of ten instruments to monitor land, oceans, atmosphere and ice caps, it will provide the most complete set of observations ever achieved, to hel

“Nuclear fusion” is the melting of light nuclei into heavier ones, a process that according to the laws of physics releases enormous amounts of energy. For the past 50 years many scientists have sought ways of harnessing this fusion reaction under controlled reactor conditions as a safe, clean and practically inexhaustible source of energy. Siegbert Kuhn and his team at the Institute of Theoretical Physics at Innsbruck University are making a major contribution to these efforts and positioning Austri

The days of fast-fading cellular phone batteries may soon be over. Researchers at the Lawrence Livermore National Laboratory (LLNL) recently developed a working prototype for a portable fuel cell energy source that could power a cellular phone 300 percent longer than existing rechargeable batteries do. Indeed, the new technology would be less expensive, smaller and more powerful than any battery currently in use, according to Jeff Morse of LLNL’s Center for Microtechnology Engineering. He predic
