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

Using tiny bone fragments from fossilized fish, scientists have traced the roots of the climate phenomenon known as El Niño, the intermittent warming of ocean waters off the coast of Peru that can affect weather worldwide. According to a report published in the current issue of the journal Science, modern El Niño conditions arose around 5,000 years ago.

Previous research based on fossilized mollusk remains had suggested that El Niño conditions did not exist thousands of years ago, but those

Thanks to ion propulsion, the Artemis mission is turning near-defeat into a success story. Nominal operations could start this summer, with ESA’s satellite, manufactured by Alenia Spazio as prime contractor (I), playing a significant role in the pursuit of high technology and advanced telecommunications.

On 12 July 2001, 30 minutes after lift-off from Europe’s spaceport in Kourou, French Guiana, it became apparent that the Ariane 5 launcher had propelled the Artemis satellite into a transf
