When you kiss your husband, does your dog try to get your attention? And does that mean that your dog feels jealous? Threatened? Or are we just imagining that?
Many if not all dog owners are sure that their pets have feelings. And we've known for a while that animals exhibit behaviors that look like jealousy, guilt and shame. But it's hard to find out what animals are really feeling. And researchers say that understanding that could give us valuable insights into human emotions, too.
South Portland, Maine, is known as the place where Liberty ships were built by tens of thousands of workers during World War II. Now, the city's waterfront is home to an oil terminal and the beginning of a 236-mile-long pipeline.
For more than 70 years, the Portland Montreal Pipeline Corp. has pumped crude oil up through the pipeline, across Maine, New Hampshire and Vermont, to be refined in Montreal.
A couple of times a month, a group of migrant women and their children gather to plant shrubs and flowers in Baltimore's expansive Patterson Park.
The gardens feed and shelter migratory birds as part of the Patterson Park Audubon Center's Bird Ambassadors program.
Neotropical birds like the black-throated blue warbler and the Baltimore oriole migrate from the East Coast down to places like Mexico and Central America for the winter, says Susie Creamer, director of urban education and conservation at the center.
This January, after the driest calendar year in California history, Gov. Jerry Brown declared a drought emergency. He called on residents to reduce their water intake by 20 percent.
But downtown Los Angeles doesn't looklike a city devastated by the state's worst drought in decades. The city is green with landscaping, and fountains are running. People still water their lawns, wash their cars and fill their pools.
In California, residents are being urged to conserve water as the state suffers from a historic drought. But a new report says the state's water use has actually gone up over the last year. California enacted statewide water restrictions this week. Those include fines of up to $500 a day. Now, to find out what actually gets people to cut their water use, NPR's Sam Sanders hit the streets of L.A.
