New Progress in Stem-Cell-Free Regenerative Medicine

Regenerative medicine and stem cells are often uttered within the same breath, for good reason.

In animal models, stem cells have reliably reversed brain damage from Parkinson’s disease, repaired severed spinal cords, or restored damaged tissue from diabetes, stroke, blood cancers, heart disease, or aging-related tissue damage. With the discovery of induced pluripotent stem cells (iPSCs), in which skin and other tissue can be reversed into a stem cell-like state, the cells have further been adapted into bio-ink for 3D printing brand new organs.

Yet stem cells are hard to procure, manufacture, and grow. And unless they’re made from the patient’s own cell supply—massively upping production costs—they’re at risk of immune rejection or turning cancerous inside their new hosts.

MIT new 3D chainmail interlock system with ten times the stiffness

Researchers invent a new approach to assembling big structures — even airplanes and bridges — out of small interlocking composite components. MIT researchers have developed a lightweight structure whose tiny blocks can be snapped together much like the bricks of a child’s construction toy. The new material, the researchers say, could revolutionize the assembly of airplanes, spacecraft, and even larger structures, such as dikes and levees.

NBF – This is huge. It boosts what is possible with additive manufacturing and 3D printing. This will revolutionize manufacturing and construction.

UPDATE – I have added a discussion of variants to the 3D interlock system and compare it to the Utility Fog concept.

NASA and Virgin Orbit have 3D-printed a working rocket engine part

They have successfully test-fired 3D-printed combustion chambers made from multiple materials.

The news: By combining their manufacturing and testing capabilities, small-satellite launcher Virgin Orbit and NASA created a rocket combustion chamber that was 3D-printed from multiple metals. A combustion chamber is the container where all the propellants get mixed up and ignite—so it must be able to cope with extreme heat and force. The test part that used the chamber generated more than 2,000 pounds of thrust in a series of 60-second test fires. You can watch a video of the test firing here.

Why are chambers a challenge? Because it has to withstand so much, it must be designed to a very high standard, meaning the part is expensive and time consuming to make.

3D printing to save dogs’ day

3D printed models of dog skulls are helping University of Queensland vets to save animals and educate tomorrow’s veterinary students.

The models, showcased at the World Science Festival, were the result of a collaboration between UQ Library’s Digital Scholars Hub and the School of Veterinary Science.

UQ veterinarian and Associate Professor Rachel Allavena used the skulls to help children understand how with short noses can suffer from the condition brachycephalia.

What Insurgency Will Look Like in 2030

With the rise of enhanced being the world will change at a fast pace similar games such as black ops 3 are a proper representation of possible outcomes in warfare. Like for instance sentient warfighting robot beings or cybernetically enhanced humans. The extremes of these also are seen in wetware which can essentially not have many limits so increased strength intelligence really anything you can imagine. Really sci-fi games such as halo are not far off at the possibilities of warfare. Really we are only limited by our imagination.

The author of “Ghost Fleet” has some guesses — and some questions that U.S. defenders will have to answer.

Robots, artificial intelligence, cyberwar, 3D printing, bio-enhancements, and a new geopolitical competition; the 21st century is being shaped by a range of momentous, and scary, new trends and technologies. We should also expect them to shape the worlds of insurgency and terrorism.

With so much change, it is too early to know all that will shake out from these new technologies in the years leading toward 2030 and beyond. But we can identify a few key trends of what will matter for war and beyond, and resulting questions that future counter-insurgents will likely have to wrestle with. Below are three, pulled from a recent New America report on what the tech and wars of 2030 might portend.

New Progress in the Biggest Challenge With 3D Printed Organs

We’re tantalizingly close to growing organs in the lab, but the biggest remaining challenge has been creating the fine networks of blood vessels required to keep them alive. Now researchers have shown that a common food dye could solve the problem.

In the US there are currently more than 100,000 people on organ transplant waiting lists. Even if you’re lucky enough to receive a replacement, you face a lifetime on immunosuppressant drugs. That’s why scientists have long dreamed of growing new organs from patients’ own cells, which could simultaneously tackle the shortage and the risk of organ rejection.

The field of tissue engineering has seen plenty of progress. Lab-grown skin has been medically available for decades, and more recently stem cells have been used to seed scaffolds—either built form synthetic materials or made by stripping cells from natural support structures—to reproduce more complex biological tissue.

Designer Julia Daviy Introduces Her Digitally Customizable 3D Printed Skirt

3D printing is moving ever closer to gaining a true home in mainstream commercial applications, thanks to the impact the technology is having on consumer fashion products such as jewelry, footwear, and clothing. While 3D printed fashion was still considered to be more of a novelty a few years ago, efforts have been increasing to make it more common – even in the classroom. Additionally, the technology is helping to usher in a more sustainable and eco-friendly way of manufacturing garments…and designer Julia Daviy is helping to lead the charge.

In addition to designing clothes, Daviy is also an ecologist and clean technology industry manager, and uses 3D printing to make cruelty-free, zero-waste clothing. She believes that the technology will change how the world produces clothing, especially when it comes to some of the more problematic issues of garment manufacturing, such as animal exploitation, chemical pollution, energy consumption, and material waste.

“Our goal was never to demonstrate the viability of 3D printed clothing and leave things at that. We’ll have succeeded when beautiful, comfortable, ethically manufactured and environmentally friendly clothes are the standard,” Daviy stated. “The innovations we’ve made on the production and marketing side of the equation are just as important as the technological breakthroughs that have gotten us this far.”
