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
Mad Science: ‘Genetically Modified Micro Humans’ to be ‘Farmed’ for Drug Testing by 2017 2014 09 12 Developers of artificial micro-humans, or ‘mini GM humans,’ are hoping to release their technology on the market by 2017. No this isn’t a sci-fi joke. Scientists are developing artificial humans in the same vein as GM plants with the hope that these creations will replace the need for using animals in laboratory testing.
Artificial humans will be ‘farmed’ with interacting ...
Friends of Rape: How Feminist Liberals Help Sex-Crime to Flourish 2014 09 12 Deafeningly. That’s how liberals would have reacted if the victims in Rotherham had been Pakistani, the rapists White and the cover-up organized by the Conservative party and its allies in the right-wing media. If the scandal had been like that, the Guardian would have boiled with righteous wrath and indignation: “The horror of it. At least 1,400 victims subject to ...
How NASA Plans to Open ’Air Highways’ for Drones 2014 09 10 If Amazon and Google are going to take their drone delivery operations public, what’s going to ensure they do it safely? Air highways and specialized drone corridors designed by NASA scientists, apparently.
Even if the Federal Administration Administration isn’t sold on the idea of commercial drones flying throughout the country, NASA is.
The agency has quietly been working on an air ...
Ancient Egyptians documented animal extinctions 2014 09 10
"What was once a rich and diverse mammalian community is very different now," the study’s lead author Justin Yeakel said.
Some six millennia ago, 37 species of large-bodied mammals roamed the deserts and river valleys of modern Egypt. Today, there are only eight. And as new research shows, ancient Egyptian art has helped tell the story of ecological loss in North ...
Internet Payment Network Paypal To Start Accepting Bitcoin 2014 09 09
EBay Inc. (EBAY)’s PayPal service will start accepting bitcoins, opening up the world’s second-biggest Internet payment network to virtual currency transactions.
“We’re announcing PayPal’s first foray into bitcoin,” Bill Ready, the chief of EBay’s Braintree unit, said at Techcrunch’s Disrupt SF conference yesterday. “Over the coming months we’ll allow our merchants to accept bitcoin. On the consumer side it will be ...
