This isn't exactly science-related, but who cares. I just discovered Neighbor Carts (in Chicago), a produce cart business. But it's not just any produce business--it's a social impact business, meaning the vendors are or were unemployed. It also fights the urban food desert problem--no or little access to healthy foods in urban neighborhoods. And the best part of all is that the produce is GOOD and CHEAP! I highly recommend shopping at a Neighbor Cart--the grocery stores can't beat the price x quality combination Neighbor Cart has. I should mention this is a joint venture between Streetwise and Neighbor Capital. Go eat more fruit!
