Local Science Issues, Dolphin Calls, Kepler Death. Nov 2, 2018, Part 1

With the midterm elections less than a week away, science is on voters’ minds even when it’s not on the ballot. From coastal floods in Florida, to the growing pains of renewable energy in Hawaii, to curbing the opioid addiction crisis in Kentucky, different stories hit closer to home depending on what state you’re in. We'll share stories of salmon conservation policy, meat substitute labeling, renewable energy expansion, and more from their respective states. And they take listener input: What’s the most important science story YOU see in your state?

The oceans can be a noisy place filled with boats and an increasing number of wind farms. The animals who call the sea home have had to adapt to the increased sounds. Researchers found that bottlenose dolphins in the Atlantic ocean off the coast of Maryland were simplifying the calls that they use to identify one another. Their results were published in the journal Biology Letters. Marine biologist Helen Bailey, who was an author on that study, talks about the benefits and costs that these adaptations have on the health of these dolphins.

This week, NASA announced we will soon be saying goodbye to another old friend. For nine years, NASA’s Kepler space telescope has been orbiting deep space, giving us an unprecedented look at the objects within it. But after confirming the existence of over 2,600 exoplanets, and extending its mission for another five and half years, Kepler has run out of fuel. NASA says that the agency will soon be sending it’s final command to the telescope, shutting it down permanently.
