I just found out that I'm the College of Science's Undergraduate Researcher of the Year at my school. Do you think it's too late to send this as new information to the programs I applied to? It's getting pretty late in the game. I don't know how big a deal this is outside of my school. But I haven't been accepted to any PhD programs yet, so I'm thinking every little bit might help.
Also, I found out that I'm going to be giving a talk at a conference where two of my potential grad. advisors will be - it will either be a good chance to meet them (so that hopefully they'll accept me), or it will be really, really awkward if I've gotten rejected from that school...

puts the pressure on giving a good talk, eh?
