Historic first images of rod photoreceptors in the living human eye - 0 views

  •  
    ScienceDaily (June 9, 2011) - Scientists have just reported that the tiny light-sensing cells known as rods have been clearly and directly imaged in the living eye for the first time. Using adaptive optics (AO), the same technology astronomers use to study distant stars and galaxies, scientists can see through the murky distortion of the outer eye, revealing the eye's cellular structure with unprecedented detail. This innovation, described in two papers in the Optical Society's (OSA) open access journal Biomedical Optics Express, will help doctors diagnose degenerative eye disorders sooner, leading to quicker intervention and more effective treatments.

The highest-resolution immersive visualization facility ever built | KurzweilAI - 1 views

    in response to comments the Editor comments: "Good points. Main benefit is a highly interactive shared exploration/discussion/planning space (and PR value), but that same functionality, including the 1.5 Gpix display (an interactive version), could be achieved in theory with an enhanced* Oculus RIFT (http://www.kurzweilai.net/why-immersive-virtual-reality-is-the-next-generation-of-gaming-part-2 and http://www.oculusvr.com/ ) with an MMORPG architecture and Kinect/Leap control in an Oblong-type shared environment (http://www.kurzweilai.net/minority-report-arrives-with-oblong-part-ii-mind-blowing-ui) at lower cost and not restricted to one room - in fact, feasible globally via machine translation (http://www.kurzweilai.net/speech-recognition-breakthrough-for-the-spoken-translated-word) and local clones of the imagery and darknet shared DB (access to Internet2 via 100 Gbps lines would also be nice). Extra points for automated POV display based on head, eye, hand, and body-motion tracking and automated EEG-based control and double points for automated mind reading (http://www.kurzweilai.net/neuroscience-the-mind-reader) tied to an NLP/semantic web DB. * "Imagine an HMD with a massive field of view and more pixels than 1080p per eye, wireless PC link, built-in absolute head and hand/weapon/wand positioning, and native integration with some (if not all) of the major game engines, all for less than $1,000 USD," Palmer says. "That can happen in 2013!" (http://www.kurzweilai.net/why-immersive-virtual-reality-is-the-next-generation-of-gaming-part-2)"

A limitless power source for the indefinite future | KurzweilAI - 0 views

  •  
    "The report  gets across one very basic message: in the eyes of the leading experts on aerospace technology worldwide: harvesting solar power in space and transmitting it to earth is no longer science fiction," says author Howard Bloom in a companion announcement by the Space Development Steering Committee. "It is sound, current-technology-based science fact.  And it is a green energy option we can't ignore.

Make plastic objects appear before your eyes - 0 views

  •  
    Everyone has experienced a broken knob or a broken piece off of an appliance. You also know that while trying to get a new one you might have a long waiting period. Well there might be a prototype that is here to solve that problem. The Thing-O-Matic claims to manifest any three-dimensional plastic object in just minutes. The machine was shown first at a Las Vegas trade fair and is meant to make manufacturing more common for the average person.\n\n3,000 have already been sold at $790 a device. This model only makes plastic objects but the manufacturers say that in the future models could make metal and plastic models to make super cool gadgets. The machines make objects that are six by six by seven inches. The machine is not capable of making images but it does make boxes, tubes and get this- even action figures!

New Scientist TV: Amputees regain control with bionic arm wired to chest - 0 views

  •  
    Jesse Sullivan, the man in this video, is using one of the most high-tech prosthetic arms available. But what's truly impressive about it isn't visible to the eye: instead of using a motor, he's controlling the arm with his thoughts. After an amputation, the nerves in a stump remain healthy, at least for a while, and now scientists are making use of this fact to create highly dexterous, thought-controlled prosthetics.

It's Official: Tunisia Now Freer than the U.S. | Informed Comment - 0 views

  •  
    An Arab country with neither secret police nor censorship is unprecedented in recent decades. Tunisia is inspiring similar demands in Egypt and Jordan. When skeptics wonder if the Revolutions of 2011 would really change anything essential in the region, they would be wise to keep an eye on these two developments in Tunisia, which, if consolidated, would represent an epochal transformation of culture and politics. Arguably, Tunisians are now freer than Americans. The US government thinks our private emails are actually public. The FBI and NSA routinely read our email and they and other branches of the US government issue security letters in the place of warrants allowing them to tap phones and monitor whom we call, and even to call up our library records and conduct searches of our homes without telling us about it. Millions of telephone records were turned over to George W. Bush by our weaselly telecom companies. Courts allow government agents to sneak onto our property and put GPS tracking devices under our automobiles without so much as a warrant or even probable cause. Mr. Obama thinks this way of proceeding is a dandy idea.

EPFL spinoff turns thousands of 2D photos into 3D images | KurzweilAI - 0 views

  •  
    Researchers in EPFL's Computer Vision Laboratory developed a computer-based modeling service that generates a 3D image from up to thousands of 2D shots, with all the processing done in the cloud. Since April, the EPFL startup Pix4D has been offering the modeling service with a fourth dimension: time. Now, individuals and small businesses looking for fast, cheap, large-scale 3D models can get them without investing in heavy processing, the company states. With Pix4D, users upload a series of photos of an object, and within 30 minutes they have a 3D image. The software defines "points of interest" from among the photos, or common points of high-contrast pixels. Next, the program pastes the images together seamlessly by matching up the points of interest. Much in the same way our two eyes work together to calculate depth, the software computes the distance and angle between two or more photos and lays the image over the model appropriately, creating a highly accurate 3D model that avoids the time intensive, "point by point" wireframe method. With Pix4D's 3D models, you can navigate in all directions as well as change the date on a timeline to see what a place looked like at different times of the year. The company is collaborating with several drone makers (including another EPFL startup,senseFly) to market their software as a package with senseFly's micro aerial vehicles, or autonomous drones. Pix4D's time element avoids waiting for Google to update its satellite data or for an expensive plane to fly by and take high-resolution photos. Farmers, for example, can now send relatively inexpensive flying drones into the air to take pictures as often as they like, allowing them to survey the evolution of their crops over large distances and long periods of time. And since the calculations are done on a cloud server, the client doesn't need a powerful computer of his or her own.
