World Record - .01 mm nano-snowman
You’re looking at the tiniest snowman ever built. Well, it looks like a snowman, but this minuscule model — about a fifth the width of a human hair — is not made out of snow. It’s constructed of two tiny tin beads that are usually used to calibrate an electron microscope, and welded together with platinum.
It’s built by David Cox, a nanotech expert at the Quantum Detection Group of Britain’s National Physical Laboratory. He’s accustomed to working with such astonishingly small objects, and used his nano-particle manipulation tools to demonstrate the astonishing accuracy of his work.
He bathed the snowman in blue light to give us this entertaining, snow-blown image. The remarkable flourish of his smiling snowman is its little happy face, carved into the top orb using a focused ion beam. That’s no small feat.

Chair In Magnet #4 - StumbleUpon
We made it a habit to bring chairs into the room but kept them at “x” distance. The story was after the procedure the patient pulled the chair closer while getting up. The chair was pulled to the magnet. The tech went to get assistance to pull the chair off and enlisted the help of a transporter who decided to start pulling before everyone was assembled. The chair flipped up and in and history was made.
This happened on the 3-11 shift. The next morning all were assembled to brainstorm. Maintenance drilled a hole in the concrete and placed an eye screw. A winch was located outside the room and with a nylon rope the chair was pulled off. After GE‘s assessment and okay, we were up and running by noon or 1pm! We were impressed that this was accomplished without a quench and significant downtime.
The shroud was cracked and the head coil was damaged; both replaced at a later time. The patient was not injured.
After 20 years and no accidents, our policy was immediately changed to stop allowing the chairs into the scan room. We recognize we were VERY lucky in many respects. -

Caleb Charland is a photographer with a love of all things science. I thought this was fitting in honor of our latest experiments with magnets in IPC.

The Levitating Mouse - The 50 Best Inventions of 2009 - TIME
“Researchers at NASA’s Jet Propulsion Laboratory, led by Yuanming Liu, have figured out how to make the tiny critters float in midair using magnets.”
Maybe our Levitron demonstration would have been more exciting with a mouse involved.
