I'm Seeing Things In Boston

I'm in Beantown with fellow Discovery News-er Tracy Steadter for a couple days visiting various labs to learn why some of them are so darn interesting. Yesterday it was a nuclear fusion lab with floating wooden cheerios and huge magnets, then the Tufts Visualization Lab (pictured). Sadly, they didn't let us keep the googly 3-D sunglasses. Today it's Boston University then a visit to Boston's greenest building.

One sort of peripheral question I have about Boston: Why are there so many Dunkin' Donuts? Seriously, Tracey says in some places there are Dunkin' Donuts across the street from Dunkin Donuts. If you've been here, you'll know exactly what I'm talking about. It…uh, it sort of makes me hungry.
