Forensic Hydrology?

How can you tell where water came from? Lets say I give you a bucket of water taken from a local water source (river, lake, etc). There's some plants and maybe a fish in it as well. What could you tell me about where this water came from, could you pinpoint which body it came from, and how would you come to this conclusion? [more inside]

How do I stop attracting the wrong guys and start attracting the right ones?

I was just broken up with by a really decent, kind guy because there was no "spark." He seemed like everything I ever wanted in a partner on paper. I knew there was no spark but I was perfectly fine with that, because it seems like the only guys I ever have mutual emotional chemistry with are either rageaholics, substance abusers, or commitmentphobes. I was more than willing to trade the spark for not being yelled at, put down, or inexplicably blown off. [more inside]

Calling all med students, past and present

Thinking back to medical school classes like Biochemistry and Pharmacology, how much foundational knowledge did you actually use from your undergrad courses in related subjects? Was it important to walk in being able to solve all of the kinds of problems you’d see in general chemistry and physics, or were concepts more important? I am trying to understand how much ‘general’ review is required for success before someone who has been admitted actually starts a medical school program.
