ESRF helps reveal the origin of the Solar System

Particles returned to Earth last January by the Stardust spacecraft from comet Wild two are yielding precious information about the origin of the solar system, thanks to the X-rays produced at several of the world's synchrotron facilities, including the ESRF. Although the particles are tiny, the beams available at synchrotrons can be even smaller, enabling researchers to illuminate the cometary material and determine the distribution of elements within the particles without damaging them.

1. MU researcher presents origin-of-life theory for young Earth
   10-02-2007 · EurekAlert!
   Scientists have been trying to find the origin of Earth's adenine and where else it might exist in the solar system. University of Missouri-Columbia researcher Rainer Glaser may have the answer. Glaser is hypothesizing the existence of adenine in interstellar dust clouds. Those same clouds may have showered young Earth with adenine as it began cooling billions of years ago, and could potentially hold the key for initiating a similar process on another planet.

   04-20-2007 · EurekAlert!
   Researchers from the European Molecular Biology Laboratory in Heidelberg now reveal that the vertebrate nervous system is probably much older than expected. The study, which is published in the current issue of Cell, suggests that the last common ancestor of vertebrates, insects and worms already had a centralised nervous system resembling that of vertebrates today.
