"Hey, Don today will report on an event that helps scientists get some insight into how to protect endangered baleen whales in two thousand three a baby fin whale was stranded on a California beach experts. Try to save the newborn, but it died while being transported to safety strategic because the number of whales declined drastically in the twentieth century because of wailing these five of the fifteen species of baleen whales are endangered the giant animals communicate using low frequency sounds that can travel hundreds of miles through the ocean, they use these sounds to find mates an organizer social structure. Unfortunately, the sounds are being drowned out by the noise of ships at sea, although whaling has been reduced by an international ban. The noise may still be a big threat. So why don't governments make regulations to limit it? They have but it's been difficult to devise the right regulations because so. So little is known about how Balian Wales here. That's why the baby whale was important. But you're the way was dead. What can you learn about whale hearing from a corpse a team of scientists from San Diego made a three dimensional map of the dead whales. Head using computed x Ray tomography. They used the map to make a computer model of its acoustic properties. The researchers found evidence that baleen whales here with their skull. Low-frequency sounds caused the skull to vibrate. And the vibrations are carried to the inner ear can the new model help scientists devise better regulations to limit ship noise. It's an important step, but much more research will still be needed perhaps the baby oil didn't die in vain. This moment of science comes from Indiana University where on the web at a moment of science dot org. I'm Yahya Cassandra darn Don glass."
