A few months ago I talked to the researcher at the Howard Hughes Medical
Institute at Janelia Farms, 5 miles from my house, who invented a
version of the binding flourescing dye system that is read by beaming a
powerful light pulse _through_ the brain and reading the resulting
flashes as "ripples in a pond" to determine the location of each
molecule so excited. Now that is some cool science. I think I have a
picture of him and HHMI somewhere.
