Congrats to my friend and colleague Guosong Hong for his stunning and original discovery, published today in Science, on clearing tissues *in living animals* with a common food dye! The dye is tartrazine, used in Doritos! https://t.co/fqVivyH0kI

It even works for three-photon imaging! And provides a huge field-of-view compared to what is typical for that approach. And again-- this is through 20 mm of air! (4/n)

This just dropped - our evaluation of intravenous injection of GCaMP. It works well & we tested sensory responses out to 34 weeks post-injection :)

Today is my first twitter post, ever. I recently interviewed Clay Reid from the Allen Institute for the journal "Neurophotonics". The interview just published today as video and text.
