A Pen That 3-D Prints Bone Right Onto Patients
The device could eventually let surgeons apply stem cells more directly
One of the greatest promises of 3-D printing is that we’ll one day be able to print organs on-demand. Need a new liver? There it is, at the push of a button.
Anticipating that future, scientists from the University of Wollongong in Australia have created the BioPen, a tool that lets physicians more or less draw new bones on peoplethrough 3-D printing. The pen is loaded with so-called “stem cell ink,” a batch of human cells that can form new bone. Another second substance, a polymer, then seals the area so the stem cells can do their work in peace. You can see why this is promising: if someone loses parts of bone in an accident, a tool like this pen could apply a fix directly to the problem area.
We’ve seen 3-D printed bones before, actually, but this device could give a little more precision. It’s yet to undergo clinical testing, so it still may be a while before it hits the market, but if and when it does, it’ll have some company.
From 1941’s Hellzapoppin’, watch this phenomenal performance by Whitey’s Lindy Hoppers, the Savoy Ballroom's supreme swing dance group founded in 1935 by Herbert “Whitey” White. This clip is annotated with the teams’ names: William Downes & Frances “Mickey” Jones (0:39). Billy Ricker & Norma Miller (1:09). Al Minns & Willa Mae Ricker (1:29). Frankie Manning & Ann Johnson (1:55).
You’ll recognize Al Minns from these classic clips with dance partner Leon James. There’s more swing in the archives. Also, don’t miss The Nicholas Brothers in another one of the greatest dance performances ever filmed.
