Ancient musical instrument comes back to life 

An ancient musical instrument can now be heard for the first time in centuries, due to the grid and a computer modelling project.

ASTRA (Ancient instruments Sound/Timbre Reconstruction Application) has recreated the sounds of the Epigonion, a harp-like  musical instrument from ancient Greece.

Most of our knowledge of the Epigonion is based on archaeological finds, historic pictures and ancient literature. It was apparently a wooden stringed  instrument with a sound that modern musicians guess sounded like a modern harp or a harpsichord. The ASTRA team members compiled the sounds of four Epigonion instruments to recreate a medieval musical piece, making this the first time that these instruments have been heard performing together.

Using archaeological data as a starting point, ASTRA team members created a virtual model of the instrument, and then reproduced the sound the instrument made by simulating its behaviour as a mechanical system.

To date the avian flu virus is not transmissible among humans, however it mutates constantly and some strains have already become resistant to current anti-viral drugs. With the possibility of a worldwide outbreak ever-present, the search for new, more powerful drugs is vital.

Using resources at the San Diego Supercomputing Center (SDSC), a team of University of California San Diego scientists has identified more than two dozen compounds that are promising candidates for use in new avian flu drugs.

First beam: 1971 at Fermilab and 2008 at the Large Hadron Collider at CERN—the proof was and is but a tiny blip on a screen. 

But when it comes to reading out data events in the detectors placed at points along the beam, a lot has changed.
