Many of the drugs we take aren't actually digested — they pass through our bodies, and down through the sewer pipes. Traces of those drugs end up in the bodies of fish and other wildlife. Nobody's sure what effect they have.
Now, a paper being published in Science magazine finds that drugs for anxiety drugs — even at these very low levels — can affect the behavior of fish.
Good morning. I'm Renee Montagne. Chocolate is bad for dogs and cats, but that doesn't mean they won't be feeling the love on this Valentine's Day. The National Retail Federation says Americans will spend more than $800 million on gifts for their pets - from heart-shaped treats to heart-healthy vitamins. And in honor of Valentine's Day, the ASPCA hosted an online dating show to match humans and animals in need of a home. They called that event "Puppy Love." It's MORNING EDITION.

It sounds like a horror story: Every few years, usually in the winter months, residents of the town of Leesburg, Va., come home from work to find their backyards overrun with turkey vultures. Not just a few birds, but hundreds of them. Everywhere.
Lt. Jeff Dube is with the town's police department. For a whole week, he spent every evening driving around town, looking for the latest vulture hotspots.
"They like Leesburg. There's really no rhyme or reason. Every three to five years they come back en mass, like this year, 2- to 300," Dube says.
Drop a cat and it will swing its head to a horizontal, rearrange its rear, arch its back, splay its legs, and — amazingly often — land on its feet.
This is what cats do. They're famous for it. But now they have a rival.
This is an aphid.
Aphids spend their days sucking sap from leaves. Those leaves can be high off the ground. "High" of course, being a relative term, but think of it this way: Five feet high up is 381 aphids tall. Which is why things get so dicey when a ladybug comes by.

Before they end up filleted and sautéed on your dinner plate, salmon lead some pretty extraordinary, globe-trotting lives.
After hatching in a freshwater stream, young salmon make a break for the ocean, where they hang out for years, covering thousands of miles before deciding its time to settle down and lay eggs in their natal stream.
So how do these fish find their way back to their home river?
