From pesticides to caffeine, chemicals that affect living organisms are making their way into the nation's rivers and streams. That's the conclusion reached by a pair of complimentary studies by the US Geological Survey (USGS) and the US EPA, both published today in the journal Environmental Science and Technology.

Cherries grow on trees, strawberries on vines, but how do cashews grow?

Of course, the downside of receiving produce from far-off lands is that we can't exactly run into the fields to see how they're grown. For many, the manner in which fruits and veggies emerge from the earth can be something of a mystery. Here are some of the more unexpected ways plants propagate before they make their way into our meals:
