There's a lot of debate these days about the cost of medical care and the risks. Is a drug for breast cancer patients worth the $100,000 price tag if it only adds a few months to a woman's life? Or should men routinely get blood tests for prostate cancer when the exam could cause more suffering than it prevents?
Well, today, a major medical group issued new ethical guidelines on whether doctors should consider cost when deciding how to treat patients. As NPR's Rob Stein reports, the group takes a provocative position.
In a double-blind test by professional violinists, most couldn't determine — by sound alone — which violin was an original Stradivarius and which was a modern instrument. Above, a 1729 Stradivari known as the "Solomon, Ex-Lambert."
In the world of violins, the names Stradivari and Guarneri are sacred. For three centuries, violin-makers and scientists have studied the instruments made by these Italian craftsmen. So far no one has figured out what makes their sound different. But a new study now suggests maybe they aren't so different after all.
OK, here's a test. Clip one is a musical phrase from Tchaikovsky's Violin Concerto in D Major. Clip two is the same phrase. The same musician plays both. But one is on a Stradivarius violin, the other on a violin made in 1980. See if you can tell the difference.
