Day 2 Recap

I woke up to the sounds of "Bell Tower" through my phone's alarm clock, and could not for the life of me understand why my husband hasn't hadn't hit snooze already, "but wait!" I realized groggily, "I'm in Florida, not in Denver, that must be the alarm I set last night." In a sleep induced haze I grabbed for my phone, dropped it inadvertantly behind the hotel bed (while it was still tolling away), finally got a handle of it and hit snooze.

Despite all this, I made it to breakfast by 7:45 am, filled up my neon green Denver Museum of Nature & Science travel mug with copious amounts of coffee and found a table to join. I had a great conversation with the folks at breakfast about how professional societies are taking a stab at social media, about Body Worlds, about anatomy, and about how to keep memberships in professional societies consistent year to year. There was also talk of scuba diving and sun catching, proof that there is life outside the lab.

OK, so what did I learn today?

1. Meghan did an incredible job presenting this morning:

AChemS 2011 MS

2. A group from Monell has made a transgenetics mouse (they put one gene, called T1R3 from humans into mice that do not have the mouse T1R3) that has the ability to "taste" sweet like a human would taste sweet- making a great model for studying behavoir and other aspects of taste.

3. The difference between habituation and adaptation. "Habituation is when the brain still gets a signal, but doesn't care. Adaption is when the sensory cells no longer send a signal to the brain." Dr. Yanina Pepino explained. She presented research showing that obese and lean women do not have a difference in the initial pleasantness or intensity of sweet foods, but lean women habituate to the pleasantness more quickly than obese women, and so stop eating earlier.
