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
DARPA’s mirror-killing membrane could change astronomy, allow total global surveillance 2013 12 06
When it launches in 2018, the James Webb Space Telescope will let us see deeper into the universe than ever before. Its enormous eye is centered around 18 octagonal mirrors which assemble to form the largest telescope mirror ever built, but someday even the James Webb Telescope (formerly the Next-Gen Space Telescope) will outlive its usefulness — and then what ...
The Nightwatchman: Crime-predicting robot aims to patrol our streets and schools 2013 12 06 Get Ready. They’ll be watching.
These new robots that are an unnerving mix between Star Wars’ R2-D2 and Doctor Who’s Daleks, are being touted as the new way to "monitor, map, and secure" the humans around them.
The robots are purported to replace security guards and watchmen, in a bid to reduce labor costs and streamline surveillance.

Microsoft’s Smart Bra Will Monitor Mood & Reduce Overeating 2013 12 06 Microsoft is designing a “smart bra” that will monitor women’s health by tracking their heart rate, her emotional state, whether or not she is over-eating and more.
Sensors in the bra detect when the wearer is bored, stressed or discouraged and send a warning signal to the woman’s smartphone that she should caution from making bad food choices.
In a paper entitled, ...
“Saint” Mandela? Not So Fast! 2013 12 06 President Barack Obama has compared him to George Washington. MSNBC’s Chris Matthews heralded him as “perhaps the world’s greatest hero.”
The Las Vegas Guardian Express dispensed with the “perhaps,” declaring in headline: “Nelson Mandela World’s Greatest Hero.”
Others have christened him “the greatest man of the 20th century.” Many revere him as “the savior” of South Africa. School children worldwide read books, ...
The Legacy of Nelson Mandela: A Dissenting Opinion 2013 12 06 Nelson Mandela, rights activist, political icon and former president of South Africa, dies age 95
There is no doubt that Nelson Mandela suffered for his cause of an end to bloody apartheid, racial segregation and government oppression in South Africa:
[Mandela was a] South African anti-apartheid revolutionary as well as a politician and philanthropist who served as President of South Africa ...
