A few years ago, when the iPhone first came out, I fell in love with an app called "Molecules." It was easy to use, the images were lovely, and I thought manipulating molecules by touch could help solve some of the problems my students had with using Cn3D.
I was all set to switch.
But I couldn't. When it came to teaching, I needed features that Molecules just didn't have.
To make a long story short, we had an SBIR grant from National Science Foundation and the good fortune to work with Molecules' developer and another brilliant engineer to make a new app called " ... Read more
We feel interesting and sometimes painful sensations when capsaicin, from chilis, and the allyl isothiocyantes from wasabi,bind to receptors in our mouths. In this article, we look at the structures that communicate information to the cell. How do they tell the cell that capsaicin or wasabi compounds are bound? Read more
