A WAY TO KEEP YOUR HEART BEATING FOREVER - A 3D-PRINTED DEVICE

 
Photo Univ of Illinois and Washington Univ
Using an inexpensive 3-D printer, biomedical engineers have developed a custom-fitted, implantable device with embedded sensors that could transform treatment and prediction of cardiac disorders.
 
The 3-D elastic membrane is made of a soft, flexible, silicon material that is precisely shaped to match the heart’s outer layer of the wall.

NUKE A CITY IN 3D

New interactive map lets users nuke any place in the world - in a simulation, of course. 
 
The NUKEMAP 3D uses Google Earth images to simulate the nuclear attack, complete with mushroom clouds. I don't suppose they see human carnage simulations. 
 
But it's necessary to camouflage the warped enjoyment of nuking a city behind words such as those from historian Alex Wellerstein, of the American Institute of Physics in Maryland, creator of a series of nuclear bombing simulators.  He says the map was designed to provide a visual and accurate simulation of what would happen if a nuclear bomb was dropped on any city in the world, to give people a better understanding of how it would affect their hometowns.   
 
I don't think that the public need this gadget to understand the nightmare of nuclear warfare.  We already know what it did to Hiroshima and Nagasaki.  Two examples that leave no room for doubt.

3D HEADGEAR FOR MOBILE VIRTUAL REALITY

 

 Called Mixed Reality, it allows you to walk around an object of your choice and see it from all angles


This VR headgear can beam digital images into real life environments. It projects a 3D image from a computer screen into your surroundings.
 
You could choose to walk around the 3D projection as if it were real. It could be a giant ant, or an art sculpture, or landmark downloaded from Google and and see it from all angles.
 
As the wearer moves, the images on the display panels move so that they align with their point of view.  This changes the angle at which they are looking at the 3D projection.  This process is done almost simultaneously so that the virtual world lines up with the real one and includes scaling and resizing.
 
The system developed by Canon of Japan runs on Windows 7 and Windows XP.  Although the technology was first announced back in 2010, the company showed off the device at the Virtual Reality Expo in Tokyo this week and said it will start selling the platform from the end of this month.

STAR WARS HOLOGRAMS FROM YOUR LAPTOP

 

 Unlike a 3-D image, a holographic projection allows the viewer to move around and get different perspectives from all angles


Help me, Obi Wan Kenobi, you're my only hope!  Remember that line on Star Wars, when Princess Leia sends a hologram message with droid Artoo Deeto?
 
Soon you may be able to send hologram messages to someone's laptop.   It will take some work but it's possible. 

Until now key elements of display size, viewing angle, frame rate, and depth of image are restricted.  But scientists at the Massachusetts Institute of Technology (MIT) think they can overcome most of those obstacles with a newly developed spatial light modulator.  They envision a holographic monitor that could be built with about $500.

Daniel Smalley, a graduate student in the MIT Media Lab and first author on the new paper, is building a prototype color holographic-video display whose resolution is roughly that of a standard-definition TV and which can update video images 30 times a second, fast enough to produce the illusion of motion. The heart of the display is an optical chip, resembling a microscope slide, that Smalley built, using only MIT facilities, for about $10.

NASA 3D MACHINE TO MAKE FOOD OUT OF BUGS

 

 


In view of earth's looming food shortage, NASA is now investing in a 3D printer which can create food out of insects, grass and algae.

What do those scientists know about future food shortages that we don't?

Well, after they've overfished and poisoned the oceans with toxics and nuclear waste, and destroyed all good seeds with their GMO tinkering, and killed all the bees and other pollinators, maybe bugs and algae will be all that will be left for us to eat. Bon appetit

DO IT YOURSELF INVISIBILITY CLOAK

 

 

 
With 3-D Printing.  Just like the 2006 invisibility cloak, the newer version deflects microwave beams, but it is hoped that a more advanced cloak will work for higher wavelengths, including visible light.
 
Three-Dimensional (3-D) Printing involves a moving nozzle guided by a computer program laying down successive thin layers of a material -- usually a polymer plastic -- until a three-dimensional object is produced.
 
"I would argue that essentially anyone who can spend a couple thousand dollars on a non-industry grade 3-D printer can literally make a plastic cloak overnight," said Yaroslav Urzhumov, assistant research professor in electrical and computer engineering at Duke's Pratt School of Engineering.

SUBMERGED LOST CITY RECREATED IN 3-D

 

 

The city of HERACLEION, where Cleopatra was inaugurated, remained hidden for 1200 years under the sea, until discovered in 2001. 

Now 3-D technology has created a map representing the city before it sank into the Mediterranean. 
 
See map, pictures of ancient artwork rescued from the depths, and short video of the still submerged ruins.  - http://www.dailymail.co.uk/sciencetech/article-2316147/Heracleion-3D-map-raises-real-life-Atlantis-deep.html
 
How many of our coastal cities will someday be nothing but underwater points of interest for scientists? What will they find? McDonald signs?
