Researchers at a Scottish university say the technology will speed up progress towards the creation of artificial human organs.
Scientists have taken a step closer to creating artificial human organs and using them for transplants after 3D printing produced clusters of stem cells.
In the short term, the technique could be used to generate tissue for drug-testing currently carried out on animals.
The 3D printing technology relies on an adjustable "microvalve", which builds up layers of human embryonic stem cells.
Such cells, which originate from early stage embryos, are blank slates with the potential to become any type of tissue in the body.
In the long term, the new printing technique could pave the way for those cells to be incorporated into transplant-ready laboratory-made organs and tissues, said researchers at Heriot-Watt University in Edinburgh.
Surgeon Anthony Atala demonstrates an early-stage experiment that could someday solve the organ-donor problem: a 3D printer that uses living cells to output a transplantable kidney. Using similar technology, Dr. Atala’s young patient Luke Massella received an engineered bladder 10 years ago; we meet him onstage. YouTube.com
Tiny Micro Robots Build Things in ‘Microfactory’ 2014 04 17 The teenie-weeniest robot uprising ever might be sooner rather than later due to the work of research institute SRI.
Don’t let these microbots’ size fool you, there is power in numbers and thousands of the robots can work together to perform tasks at dizzying speed.
SRI International has developed a new generation of ant-like robots that can work as ...
"A world of pure imagination": How Occupy turned to "anarchy" 2014 04 17
In the closing ceremonies of London’s 2012 Summer Olympics, comedian Russell Brand, perched atop the Beatles’ "Magical Mystery Tour" bus, opened his performance by singing the first lines of "Pure Imagination" from the movie Willy Wonka:

Artists ’have structurally different brains’ 2014 04 17
Artists have structurally different brains compared with non-artists, a study has found.
Participants’ brain scans revealed that artists had increased neural matter in areas relating to fine motor movements and visual imagery.
The research, published in NeuroImage, suggests that an artist’s talent could be innate.
But training and environmental upbringing also play crucial roles in their ability, the authors report.
As in many areas ...
NSA-proof email service goes online 2014 04 17 A new email service that protects its users from the prying eyes of the NSA and other spy agencies has gone online. The service’s creators say it will make encrypted messaging accessible to all and curtail internet snooping.
Germany-based Lavaboom was inspired by Lavabit, the encrypted email service that was believed to have been used by whistleblower Edward Snowden before it ...
