I've been at McMaster University in Hamilton, Ontario, today shooting a piece for Planet Green. While I can't talk about that yet, I can show you these awesome pictures that Dr. Ray LaPierre of the Department of Engineering showed me. (This is the first time they've been online, to my knowledge.)

Dr. LaPierre's group used a focus ion beam microscope (FIB) to shoot a beam of gallium ions at the surface of a human hair, carving atoms off the of the surface of the hair to etch these McMaster University logos. When not tattooing hair, they'll use the FIB microscope to fabricate nanoscale devices.
Sorry for big pics.

That close up you can really tell that the hair is comprised of dead cells. Eww.

If you think about it, this whole thing could be photoshoped so easily.

Yeah, but that is what hair looks like up close, so I maintain my "eww" diagnosis.

hair is cylindrical right?

So why is there not curvature on that text?

Date of pics: 14 Feb.
While others enjoy their love with each other, and celebrate it on this commercially biased day, McMaster University decides to singe some hair strands. Well done!

Yeah, I'm kind of skeptical. That is a really easy photoshop. But then again, I don't really know why someone would care enough to fake it...

It's not photoshoped. If it was photoshoped it's more professional than it appears. You can see the detail behind the burns and on the ridges of the detail where it missed spots. I don't about you guys but that isn't that easy to do that perfect.
