Scientists at Princeton University used off-the-shelf printing tools to create a functional ear that can “hear” radio frequencies far beyond the range of normal human capability
The researchers’ primary purpose was to explore an efficient and versatile means to merge electronics with tissue. The scientists used 3D printing of cells and nanoparticles followed by cell culture to combine a small coil antenna with cartilage, creating what they term a bionic ear.
3D-printing, like decentralized crypto currencies, have the potential to change the world in which we live in extraordinary ways. Ways that are almost inconceivable at this point given we are so early in the game. More than anything else, these technologies can empower the individual like never before, and I think that is generally a very good thing.
I first covered the impact of 3D-printing on the firearms industry in January in my post 3D-Printing Meets the 2nd Amendment, where I discussed Defense Distributed’s success in printing magazines for semi-automatic weapons. At the time, their next major goal was to print a fully functioning firearm. They have now done just that.
Eight months ago, Cody Wilson set out to create the world’s first entirely 3D-printable handgun.
Now he has.
Early next week, Wilson, a 25-year University of Texas law student and founder of the non-profit group Defense Distributed, plans to release the 3D-printable CAD files for a gun he calls “the Liberator,” pictured in its initial form above. He’s agreed to let me document the process of the gun’s creation, so long as I don’t publish details of its mechanics or its testing until it’s been proven to work reliably and the file has been uploaded to Defense Distributed’s online collection of printable gun blueprints at Defcad.org.
All sixteen pieces of the Liberator prototype were printed in ABS plastic with a Dimension SST printer from 3D printing company Stratasys, with the exception of a single nail that’s used as a firing pin. The gun is designed to fire standard handgun rounds, using interchangeable barrels for different calibers of ammunition.
SAN DIEGO – An inside source gave Team 10 a picture snapped inside the San Onofre Nuclear Generating Station (SONGS) showing plastic bags, masking tape and broom sticks used to stem a massive leaky pipe.
San Onofre owner Southern California Edison (SCE), confirms the picture was taken inside Unit Three, but did not say when. The anonymous source said the picture was taken in December 2012.
Unit Three is the same unit that leaked radiation in January 2012. SONGS has been shutdown since then as a precaution.
“[Staff] identified a small leak in the water box and will perform maintenance per our scheduling process,” SCE spokeswoman Maureen Brown wrote in a statement. “In the meantime, plastic is in place to direct the water from the small leak to a drain.”
“If that’s nuclear technology at work and that’s how we’re going to control leaks I think the public should know,” the inside source said.
Chicago almost became a glowing radioactive sister city to Fukushima.
Yesterday we broke the story of the La Salle Nuclear plant having to perform a Fukushima style direct-to-atmosphere venting of the primary nuclear containment due to a lightening strike. As we indicated at the time, the amount of radioactivity released is unknown because the radiation monitors were not on a backup power supply.
Today in a follow on NRC event report, we find out that failures in the emergency cooling system resulted in the last ditch cooling attempt of directly venting the radioactive drywell to the atmosphere. The severity of those failures are underreported in the NRC event report, because it reads no different than if it the failures had been discovered during testing instead of being found out in the midst of a real life emergency resulting in the last ditch cooling effort of venting.
We explain the situation in more detail in the video, but gist of the analysis is as follows: Continue reading »
Highest ever energy conversion efficiency without solar concentration
Increased efficiency for ground-based applications
SYLMAR, Calif., April 9, 2013 — A Spectrolab solar cell recently set a world record by converting more energy from the sun into electricity than any other ground-based solar cell without solar concentration.
The Boeing [NYSE: BA] subsidiary’s achievement in ground-based solar cell efficiency was verified by the U.S. Department of Energy’s National Renewable Energy Laboratory in Golden, Colo.
The cell converted 37.8 percent of solar energy using a new class of high-efficiency multi-junction solar cell, created from two or more materials and leveraging Boeing technology that makes semiconductor materials more reliable. The record was set without concentration, the common practice of having lenses or mirrors focus solar rays on the cells.
Watch the video embedded below: It reveals the “Petman” humanoid robot funded by the Department of Defense. Like something ripped right out of a sci-fi movie, the robot sweats to regulate body temperature, and it can be dressed in chemical suits, camo or other uniforms to resemble humans. The picture you see at the top of this article is take from the actual humanoid robot currently under development.
Have no illusions about where this is headed: The Pentagon wants to develop and deploy a robotic army of autonomous soldiers that will kill without hesitation. It’s only a matter of time before these robots are armed with rifles, grenade launchers and more. Their target acquisition systems can be a hybrid combination of both thermal and night vision technologies, allowing them to see humans at night and even detect heat signatures through building walls.
BERKELEY — Three UC Berkeley scientists were among a gathering of the nation’s top scientists at the White House this morning (Tuesday, April 2) as President Barack Obama announced a major national initiative to develop new tools to create real-time traffic maps of the human brain.In a White House briefing, Obama proposed an initial $100 million investment this year in the Brain Research through Advancing Innovative Neurotechnologies (BRAIN) initiative, which “ultimately aims to help researchers find new ways to treat, cure, and even prevent brain disorders, such as Alzheimer’s disease, epilepsy, and traumatic brain injury,” according to a White House press release.
“There is this enormous mystery waiting to be unlocked, and the BRAIN Initiative will change that bygiving scientists the tools they need to get a dynamic picture of the brain in action and better understand how we think and how we learn and how we remember,” Obama said. “That knowledge could be — will be – transformative.”
President Obama announced plans this morning for a long-term research project to improve our understanding of the brain. Comparing it to the Human Genome Project, Obama said the brain-mapping initiative could lead to cures for diseases like Alzheimer’s and autism, while fueling economic growth and job creation. Here’s what you need to know.
The announcement has been hotly anticipated since mid-February, when The New York Times reported the President would soon seek funds from Congress to “examine the workings of the human brain and build a comprehensive map of its activity, seeking to do for the brain what the Human Genome Project did for genetics.” At the time, we and others speculated that Obama’s plan would resemble a so-called Brain Activity Map (a.k.a. “BAM”) project outlined last year in the journal Neuron, and that the Administration might seek billions of dollars from Congress to set things in motion.
In fact, Obama announced this morning that the project will be called the BRAIN Initiative. The initial price tag: a paltry (relatively speaking) $100 million.
BRAIN stands for “Brain Research through Advancing Innovative Neurotechnologies,” and the last word in that acronym is a telling one. When we spoke with Rafael Yuste (one of the neuroscientists whose advice the Obama Administration has sought in planning the initiative) back in February, he told us that the endeavor would be first and foremost “a technical development project.” The ultimate goal of the BRAIN may be to create a functional map of neuron activity throughout the human brain, but charting such a map is – as of today – impossible.
