Speeding fresco reconstruction
Computer scientists at Princeton University in New Jersey have developed an automated system that could speed a painfully slow task facing archaeologists – reconstructing ancient artifacts from thousands of tiny, often-eroded pieces. David Dobkin, computer science professor and dean of the faculty at Princeton, got the inspiration for the project after visiting the archaeological site of...

Byproduct of the bailout
Maybe the idea of bailing out the Big Three automakers is not appetizing for anyone but, say, the Big Three. Just the same, the simultaneously declared bankruptcy could sink a long list of businesses, employees and industries, not the least of which is our own. That’s because we’re keeping company with the same auto suppliers, communities and regions perched on the brink by reports of the...
