A layer of human skin made from stem cells by a 3d printer

Guys, this is SO MUCH HUGER than this image. They actually have systems under development that can print directly into a wound.

The bioprinter has a built-in laser scanner that scans the wound and determines its depth and area. The scan is converted into three-dimensional digital images that enable the device to calculate how many layers of skin cells need to be printed on the wound to restore it to its original configuration. The system has successfully printed skin patches 10 cm square on a pig

Ten years. that’s how long they reckon until this is commonplace. Ten years.

3D printer makes tiniest human liver ever

They’ve grown a working human bladder and a small kidney, too, this shit’s game-changing

Guys pay attention this is IMMENSE

if i had to choose between DNA and RNA, i would choose RNA because it has U in it

Oh yeah!

We do this in the AsapSCIENCE office too. (xkcd)

DNA: A Love Story

Cytosine nudged Guanine and he cleared his throat uncomfortably.

"Hey. So, as your friends we thought you should know. Um. We saw Adenine last night um at RNA and, well, he was sort of with someone else."

Thymine looked up, clearly enraged. “With… with who?”

"Uracil"

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.
