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
Is Sweden Raising a Generation of Brats? 2014 03 07 Scandinavian country’s child-centric ways stir backlash
Is Sweden raising a generation of brats?
The country has built a child-friendly reputation on its mandates for long parental leave and provision for state-funded day care from age 1. But a new book paints an ugly underbelly to Scandinavia’s child-centric ways. Youngsters here—deemed "competent individuals" by the state and legally protected from spanking—are becoming the ...
Archaeologists unearth ‘unparalleled’ pre-Christian temple in Norway 2014 03 07
A fascinating discovery is shedding light upon pre-Christian Scandinavian religion and early Christian inroads into Norway. In the Norwegian press, this highly important find is being called “unparalleled,” “first of its kind” and “unique,” said to have been “deliberately and carefully hidden” – from invading and destructive Christians.
Located at the site of Ranheim, about 10 kilometers north of the Norwegian ...
Earth raises a plasma shield to battle solar storms 2014 03 07
Earth can raise shields to protect itself against solar storms.
For the first time, satellites and ground-based detectors have watched as the planet sends out a tendril of plasma to fight off blasts of charged solar matter. The discovery confirms a long-standing theory about Earth’s magnetic surroundings and offers us a way to keep track of the planet’s defences.
"It’s changed ...
The Ring of Brodgar, the Neolithic Henge of Orkney Island 2014 03 06 On the largest island of Orkney, Scotland called The Mainland, amongst the rugged cliffs and almost constant wind, there sits a Neolithic henge and stone circle known as The Ring of Brodgar. It is the third largest circle in the British Isles after Avebury & Stonehenge. Built in a true circle, the Ring of Brodgar is thought to have been ...
Ancient Egyptian Soldier’s Letter Home Deciphered 2014 03 06 A newly deciphered letter home dating back around 1,800 years reveals the pleas of a young Egyptian soldier named Aurelius Polion who was serving, probably as a volunteer, in a Roman legion in Europe.
In the letter, written mainly in Greek, Polion tells his family that he is desperate to hear from them and that he is going to request ...
