Brain-rainbows of great beauty from GM mice

Update: Looks like Pesco got to this one earlier this week!

Guido sez, "GM mice modified to have their neurons of 90 shades of color, each one shining in its unique way. A clever trick (this is a true example of biohacking) allow differential expression of color markers in each neuron in a way analogue to the display of pixels in a monitor.
This will really improve things for people who does brain research and study the way the brain is wired. Santiago Ramon y Cajal would be very excited about this.
Besides this, the pictures are exquisitely beautiful, this is bioart too."

Ira Flatow did a great segment with the principal researcher this week on the NPR show Science Friday (this is one of the two science podcasts I'm religiously devoted to, the other being CBC's Quirks and Quarks — having these shows in my earbuds once a week is one of the coolest things about living in the twenty-first century).
