Two of the biggest challenges with today’s desktop 3D printers are that they 1) don’t print very large objects and 2) are painfully slow. The Solidator 3D printer aims to change both of those things, in a printer that costs less than $5,000.

HOMESTEAD, Fla. — An international competition to pave the way for a new generation of rescue robots was dominated by a team of Japanese roboticists who were students in the laboratory of a pioneer in the design of intelligent humanoid machines.
The early roboticist, Hirochika Inoue, began working in the field almost a half-century ago at the University of Tokyo, and in the mid-1990s led the design of robots that could both walk and manipulate objects.
Students from the lab where Dr. Inoue did his early work, who then studied under Masayuki Inaba, a roboticist who was one of Dr. Inoue’s pupils, emerged as the clear leaders at the Pentagon’s Darpa Robotics Challenge 2013 Trials on Friday and Saturday.
Thinking about building a home on Mars, but having trouble finding a contractor? That might no longer be such a problem, thanks to a new technology that one day could make it much faster to build one there than it takes us now on Earth. A professor at the University of Southern California has designed an automated 3D printer that, he says, would make it “possible to build an entire home within a day.” “You press a button and it will be built,” says Behrokh Khoshnevis, who teaches industrial and systems engineering at USC.
The process, called “Contour Crafting,” was conceived as a way to quickly construct emergency housing on this planet out of concrete. But NASA sees other applications for Khoshnevis’ homebuilding innovation — for starters, projects such as an airport on the moon. “Behrokh’s work is one of the most creative and far reaching concepts I’ve seen,” said Jason Derleth, the program manager for NASA Innovative Advanced Concepts, in a news release this past summer. “He really has a chance to change the world by robotically printing buildings here, and he may even change the next human world by doing the same on the moon and Mars.”

Here’s an interesting idea: Maybe your company could be raising extra money by using its data center to mine for bitcoins at night.
The thought was half seriously suggested by Jason Langone, director of Federal Sales at a hot Valley startup called Nutanix. He wrote a blog post that explains how it could be done.

In just the past two years, it seems as if drones are everywhere in the news. This technology has been around for more than 60 years, but has only recently captured both national and international attention. This is primarily because of the increasing use in the military, but also because of concerns that such technology will be turned on a country’s own citizens.
The average person thinks of a drone as a flying spy camera, loitering overhead waiting to spot a target and then possibly launching a weapon when that target is labeled as a threat. To be sure, this is indeed one mission of drones, typically of organizations like the CIA.
However, this is by far the least common mission. The vast majority of military drone missions today are data and image collection. Their ability to provide “situational awareness” to decision makers on the ground is unparalleled in military operations since drones can essentially conduct perch and stare missions nearly endlessly.

The printer will be available to the public in early 2014 for about $1,400. CEL CEO Chris Elsworthy said the machine could someday be used to 3D scan an object or ice a cake.
In 1999, my elementary school got every single kid to love computer class with a single move: It replaced a fleet of Macintosh Classic IIs with iMac G3s. The candy-colored shells, bright graphics and whimsical shape made it feel like you were spending time with some hip, space-age machine. Computing was so in that year.
The G3 bas been discontinued for a decade, but it is still an icon of the optimism of the computing industry in the 1990s. 3D printers are going through a similar phase right now, as machine after machine hits the market. While they haven’t quite hit the ease-of-use of a 1990s era computer, they’re certainly getting there.
The Robox, a $1,400 3D printer that completed a fundraising campaign on Kickstarter today after raising more than $450,000, is the G3 of the 3D printing world. It comes in bright green or blue and has bold curves. From the side, it kind of looks like an iMessage bubble. It’s a beautiful machine that comes with a claim that’s very common these days: “accessible to all.”
| (Nanowerk News) Three stakeholder groups agree that regulators are not adequately prepared to manage the risks posed by nanotechnology, according to a paper published in the peer-reviewed journal PLOS One (“Expert Views on Regulatory Preparedness for Managing the Risks of Nanotechnologies”). | |
| In a survey of nanoscientists and engineers, nano-environmental health and safety scientists, and regulators, researchers at the UCSB Center for Nanotechnology in Society (CNS) and at the University of British Columbia found that those who perceive the risks posed by nanotechnology as “novel” are more likely to believe that regulators are unprepared. Representatives of regulatory bodies themselves felt most strongly that this was the case. “The people responsible for regulation are the most skeptical about their ability to regulate,” said CNS Director and co-author Barbara Herr Harthorn. | |
| “The message is essentially,” said first author Christian Beaudrie of the Institute for Resources, Environment, and Sustainability at the University of British Columbia, “the more that risks are seen as new, the less trust survey respondents have in regulatory mechanisms. That is, regulators don’t have the tools to do the job adequately.” |

In post-apocalyptic North America, the Capitol composed of the elite and the rich, controls 12 Districts of Panem. Every year, two representatives from each district are chosen, one boy and one girl, to compete for food supply, thrown in the arena created by the Capitol to fight. Only can be the winner. They called it – Hunger Games
.
Based on Suzanne Collins’ trilogy novel, “The Hunger Games” has created immense popularity among movie and novel enthusiasts. But for some, it has drawn fears and futuristic theories. They fear that Hunger Games can be our future predictive scenario. Who wouldn’t blink at an idea like this?
World hunger, in its basic definition, is the want and scarcity of food aggregated to the world level. Evidently, a disparity between human and food resources can cause unparalleled precondition – hunger revolution. Now, with a place ravaged by war, greed, statuses, and human right abuses, ask yourselves, “Are you the next Katniss and Peeta? Or are you part of the Capitol using food hoarding and killing as form of entertainment?”
US scientists have performed a dramatic reversal of the ageing process in animal studies.
They used a chemical to rejuvenate muscle in mice and said it was the equivalent of transforming a 60-year-old’s muscle to that of a 20-year-old — but muscle strength did not improve.
Their study, in the journal Cell, identified an entirely new mechanism of ageing and then reversed it.
Other researchers said it was an “exciting finding”.
