Forget the 3D Printer: 4D Printing Could Change Everything

Posted by in category: 3D printing

By Randy Rieland — Smithsonian.com

These days, 3D printing seems to be at the core of most new new research ventures, whether it’s developing ways to print entire meals or recreating facial features to repair a patient’s face.

But Skylar Tibbits wants to up the ante: He’s hoping 4D printing will be the thing of the not-so-far future.

The name for his concept, Tibbits admits, was a bit lighthearted at first. At the Massachusetts Institute of Technology, Tibbits and researchers from the firms Stratasys and Autodesk Inc were trying to come up with a way of describing the objects they were creating on 3D printers—objects that not only could be printed, but thanks to geometric code, could also later change shape and transform on their own.

The name stuck, and now the process they developed—which turns code into “smart objects” that can self-assemble or change shape when confronted with a change in its environment—could very well pop up in a number of industries, from construction to athletic wear.

The Next Startup Craze: Food 2.0

Posted by in categories: business, food


By Ted Greenwald — MIT Technology Review

Most tech startups are silent spaces where earbud-clad engineers peer into monitors. Not Hampton Creek Foods. The two-year-old company’s office—a filled-to-bursting space in San Francisco’s South of Market tech hotbed—grinds, clatters, and whirs like a laundromat run amok. That’s the sound of industrial-strength mixers, grinders, and centrifuges churning out what the company hopes is a key ingredient in food 2.0: an animal-free replacement for the chicken egg.

Silicon Valley venture capitalists have funded several food-related startups in the past year, but Hampton Creek has gathered the most momentum. It has A-list investors including Founders Fund, Horizon Ventures, and Khosla Ventures, and two undisclosed industrial food companies are experimenting with its plant-based egg substitute. The prepared-food counter at Whole Foods began using the startup’s egg-free Just Mayo mayonnaise in September 2013, with four other mainstream grocery chains lined up for the first half of this year. And, thanks to a recent investment round that boosted Hampton Creek’s funding to $30 million and drew in Li Ka-shing, the wealthiest person in Asia, Just Mayo soon will be sold by a large online grocer in Hong Kong.

‘Killer robots’ to be debated at UN

Posted by in categories: robotics/AI, security

BBC
Robot

Two robotics experts, Prof Ronald Arkin and Prof Noel Sharkey, will debate the efficacy and necessity of killer robots.

The meeting will be held during the UN Convention on Certain Conventional Weapons (CCW). A report on the discussion will be presented to the CCW meeting in November. This will be the first time that the issue of killer robots, or lethal autonomous weapons systems, will be addressed within the CCW.

Scientists Reconnect Severed Nerves With Liquid Metal

Scientists Have Reconnected Severed Nerves with Liquid Metal

Get your T-1000 jokes ready, because we’re one step closer to liquid metal-powered people. As a team of Chinese biomedical engineers recently used an alloy to close the gap between severed sciatic nerves in frogs. In effect, it made electronic circuits out of nerves — and it worked.

Shockingly, this sci-fi solution is as simple as it sounds. Looking for a way to keep muscles active while nerves healed, the Tsinghua University researchers identified liquid metal as a highly conductive but also safe material to bridge the gap. They decided on the liquid metal alloy gallium-indium-selenium, a benign material that’s liquid at body temperature. (This liquid metal is not to be confused with the brand-name wonder material Liquidmetal, which is not actually a liquid.) The liquid metal alloy is also highly conductive.

The Lifeboat Foundation Worldwide Ambassador Mr. Andres Agostini’s own Applied Non-Theological Omniscience defined:

Applied Non-Theological Omniscience defined:

“… Applied non-theological omniscience consists of having total knowledge; knowing everything, having infinite knowledge, the current state of knowledge, the ability to know anything that one chooses to know and can be known and actually knowing everything that can be known. Synonyms to omniscience include panshopy, polyhistory and all-knowingness …”

Transformative and Integrative Risk Management (TAIRM) methodology, under applied omniscience, is the theme of the White Swan idea.

Interstellar may be the first movie that shows realistic warp travel

Posted by in category: space travel

Jesus Diaz — SPLOID

At last we got to see the full trailer for Chris Nolan’s Insterstellar. The drama seems centered around a worldwide food crisis fired by climate change and resource depletion—a quite probable future. The space travel part seems equally plausible, showing what may be the first realistic depiction of a real warp drive.

Of course, warp drives are not real. Yet (hopefully?) But physicist have theorized about it and NASA has a small group of people working on them. I’m firmly in the camp of “if we can imagine it, we can build it.” But we will get to that later. Watch the trailer first:

Why Virtual Reality Will Compete with the Real World

Posted by in category: virtual reality

Philip Rosedale — MIT Review

Recent weeks have been good ones for people interested in virtual reality. The Facebook acquisition of Oculus has galvanized the idea that “something wonderful” will happen if we put on these strange headsets and visually enter other worlds. Of course, most people assume this means gaming.

And it’s true that the upcoming Crystal Cove Oculus headset (which tracks the head’s position and rotation) will immerse its users in the most amazing computer gaming experiences they could have ever thought possible. But that’s not the big part of the story.

After we’ve had the Oculus strapped to our faces for a few months and the novelty has worn off, we might find ourselves asking some important questions: “Where are the other people?” And “Where can I start working and learning and building in here?”

The Mathematics of Murder: Should a Robot Sacrifice Your Life to Save Two?

Posted by in categories: ethics, robotics/AI

— Popular Science

It happens quickly—more quickly than you, being human, can fully process.

A front tire blows, and your autonomous SUV swerves. But rather than veering left, into the opposing lane of traffic, the robotic vehicle steers right. Brakes engage, the system tries to correct itself, but there’s too much momentum. Like a cornball stunt in a bad action movie, you are over the cliff, in free fall.

Your robot, the one you paid good money for, has chosen to kill you. Better that, its collision-response algorithms decided, than a high-speed, head-on collision with a smaller, non-robotic compact. There were two people in that car, to your one. The math couldn’t be simpler.
