¿Ayudo? This literally means "I help?" I was struggling with my keys outside of the gate today and a gentleman asked "¿Ayudo?" I realized that he was asking me if I needed help, so I said "No, gracias." I'm learning some of the shortened ways of saying things here ... little by little. In the same way that we may not say, "Can I assist you?" or "Do you need help?" , we might just say "Need help?"
Today, I gave a seminar titled "Taller para Escuela Graduada" which means "Workshop for Graduate School." It was in the ChEMTox lab: http://chemtoxumet.blogspot.com/, and yes, the talk was in English!
The photos are from that seminar.
