Implant Gives Grayscale Vision To the Blind Using Lasers

Implant Gives Grayscale Vision To the Blind Using Lasers:
MrSeb writes with a bit from Extreme Tech: "After a lot of theorizing, posturing, and non-human trials, it looks like bionic eye implants are finally hitting the market — first in Europe, and hopefully soon in the U.S. These implants can restore sight to completely blind patients — though only if the blindness is caused by a faulty retina, as in macular degeneration (which millions of old people suffer from), diabetic retinopathy, or other degenerative eye diseases. ... The Bio-Retina, developed by Nano Retina, is a whole lot more exciting. The Bio-Retina costs ... around the $60,000 [and] the 576-pixel vision-restoring sensor is actually placed inside the eye, on top of the retina. The operation only takes 30 minutes and can be performed under local anesthetic. Once installed, 576 electrodes on the back of the sensor implant themselves into your optic nerve. The best bit, though, is how the the sensor is powered: The Bio-Retina system comes with a standard pair of corrective lenses that are modified so that they can fire a near-infrared laser beam through your iris to the sensor at the back of your eye. On the sensor there is a photovoltaic cell that produces up to three milliwatts — not a lot, but more than enough."

Asimov's Psychohistory Becoming a Reality?

Asimov's Psychohistory Becoming a Reality?:



northernboy writes "Today's LA Times has an article describing how a Wikileaks data dump from Afghanistan plus some advanced algorithms are allowing accurate predictions about the behavior of large groups of people. From the article: 'The programmers used simple code to extract dates and locations from about 77,000 incident reports that detailed everything from simple stop-and-search operations to full-fledged battles. The resulting map revealed the outlines of the country's ongoing violence: hot spots near the Pakistani border but not near the Iranian border, and extensive bloodshed along the country's main highway. They did it all in just one night. Now one member of that group has teamed up with mathematicians and computer scientists and taken the project one major step further: They have used the WikiLeaks data to predict the future.' Considering they did not discriminate between types of skirmish, but only when and where there was violence, this seems like an amazing result. It looks like our robotic overlords will have even less trouble controlling us than I previously thought."

3D, light-trapping solar cells successfully fabricated by Solar3D

3D, light-trapping solar cells successfully fabricated by Solar3D:
3D, lighttrapping solar cells successfully fabricated by Solar3D
Solar3D probably isn't a company you're particularly familiar with... at least not yet. The California-based manufacturer has just successfully fabricated a three dimensional solar panel that traps sun light in nano-scale wells on a silicon wafer. Perhaps most exciting, the prototype panel was built using off-the-shelf tech from Panasonic, meaning that the price of mass production shouldn't be prohibitively high. More testing is needed, but the resulting panels should be up to 50 percent more efficient than current generation 2D ones. For a few more details, check out The PR after the break.

Unlucky Breaks: When Hollywood Gets Blindsided by Bad Timing

Unlucky Breaks: When Hollywood Gets Blindsided by Bad Timing: When The Watch hits theaters in July, 20th Century Fox is banking on stars Jonah Hill and Ben Stiller to bring in the viewers. But the movie, about a pack of subdivision-patrolling buddies who stumble on an alien invasion, took a dark turn in March thanks to some unforeseen circumstances. The first trailer—released at the height of outrage over the shooting of teenager Trayvon Martin by a neighborhood-watch captain—showed Jonah Hill pretending to shoot at a child from a car window. The macabre coincidence got the trailer pulled (and the film's title changed from Neighborhood Watch), but The Watch isn't the first movie to suffer from terrible timing. Here are some of the most cringe-worthy examples.

Solar system ice: Source of Earth's water

Solar system ice: Source of Earth's water: Scientists have long believed that comets and, or a type of very primitive meteorite were the sources of early Earth's volatile elements. Understanding where these volatiles came from is crucial for determining the origins of both water and life. New research focuses on ice that was distributed throughout much of the early Solar System. The team's findings contradict prevailing theories and suggest that meteorites are the most-likely sources of the Earth's water.

Controlling your computer with your eyes

Controlling your computer with your eyes: Millions of people suffering from multiple sclerosis, Parkinson’s, muscular dystrophy, spinal cord injuries or amputees could soon interact with their computers and surroundings using just their eyes, thanks to a new device that costs less than £40. Composed from off-the-shelf materials, the new device can work out exactly where a person is looking by tracking their eye movements, allowing them to control a cursor on a screen just like a normal computer mouse.

Has the 3-D Hype Bubble Finally Popped?

Has the 3-D Hype Bubble Finally Popped?:
An anonymous reader writes "An article at Time speculates that the recent hype surrounding 3-D display technology has finally peaked and begun to subside. As evidence, they point to comments from Nintendo president Satoru Iwata, who does not seem particularly enthusiastic about it, and concedes it won't be a major selling point if the company continues to have 3-D enabled products in the future. He said, 'So, now we've created the 3DS and 3DS XL and also have some games out there that are really using that 3D effect that we can see, from my point of view, that it's an important element. But as human beings are this kind of surprise effect wears off quickly, and just [having] this 3D stereoscopic effect isn't going to keep people excited.' Revenue from 3-D films is also dropping, and while 3-D television sales are rising, only 14 percent of potential buyers think 3-D is a 'must have' feature."

MIT Creates Car Co-Pilot That Only Interferes If You're About To Crash

MIT Creates Car Co-Pilot That Only Interferes If You're About To Crash:
MrSeb writes "Mechanical engineers and roboticists working at MIT have developed an intelligent automobile co-pilot that sits in the background and only interferes if you're about to have an accident. If you fall asleep, for example, the co-pilot activates and keeps you on the road until you wake up again. Like other autonomous and semi-autonomous solutions, the MIT co-pilot uses an on-board camera and laser rangefinder to identify obstacles. These obstacles are then combined with various data points — such as the driver's performance, and the car's speed, stability, and physical characteristics — to create constraints. The co-pilot stays completely silent unless you come close to breaking one of these constraints — which might be as simple as a car in front braking quickly, or as complex as taking a corner too quickly. When this happens, a ton of robotics under the hood take over, only passing back control to the driver when the car is safe. This intelligent co-pilot is starkly contrasted with Google's self-driving cars, which are completely computer-controlled unless you lean forward, put your hands on the wheel, and take over. Which method is better? A computer backup, or a human backup? I'm not sure."

Is Pluto a Binary Planet?

Is Pluto a Binary Planet?:
astroengine writes "If the Pluto-Charon system were viewed in a similar way to binary stars and binary asteroids, Pluto would become a Pluto-Charon binary planet. After all, Charon is 12% the mass of Pluto, causing the duo to orbit a barycenter that is located above Pluto's surface. Sadly, in the IAU's haste to define what a planet is in 2006, they missed a golden opportunity to define the planetary binary. Interestingly, if Pluto was a binary planet, last week's discovery of a fifth Plutonian moon would have in fact been the binary's fourth moon to be discovered by Hubble — under the binary definition, Charon wouldn't be classified as a moon at all."

DARPA fights fire with sound and electricity, hopes 'ionic wind' could save lives in the field

DARPA fights fire with sound and electricity, hopes 'ionic wind' could save lives in the field:
DARPA develops method of extinguishing fire with sound and electricity, hopes 'ionic wind' could save lives in the field
Fire, frenemy of humanity since time immemorial. Typical extinguishing methods have involved water, chemicals and even blankets, but DARPA wanted to see if there was another, more pragmatic way. Starting with the understanding of fire actually being a cold plasma, DARPA then explored fire's electromagnetic and acoustic qualities, and discovered two potential ways to quell the flame, one using electrons, the other, sound. The electron technique creates an oscillating field that separates the fire and fuel dubbed "ionic wind," the other method creates an acoustic field that increases the air velocity (thinning the the flame boundary) and causes the flames to widen and drop in temperature, dispersing the fire's energy. The concepts have been proven, but scaling these up to real world solutions is a whole different matter. Light up the videos after the break to see them in action.

Brain activity changes may reduce risk of Alzheimer's

Brain activity changes may reduce risk of Alzheimer's: Activity lingers longer in certain areas of the brain in those with Alzheimer’s than it does in healthy people, researchers who created a map of the brain found. The results suggest varying brain activity may reduce the risk of Alzheimer’s disease.

New model of Alzheimer's disease developed

New model of Alzheimer's disease developed: Scientists have developed the first cell-based model of Alzheimer's disease (AD) by reprogramming skin cells of Alzheimer's patients to become brain cells that are affected in Alzheimer's. This will allow researchers to work directly on living brain cells suffering from Alzheimer's, which until now had not been possible.

Our brains often fail to notice key words that can change the whole meaning of a sentence

Our brains often fail to notice key words that can change the whole meaning of a sentence: After a plane crash, where should the survivors be buried? If you are considering where the most appropriate burial place should be, you are not alone. Scientists have found that around half the people asked this question, answer it as if they were being asked about the victims not the survivors. Far from processing every word we read or hear, our brains often do not even notice key words that can change the whole meaning of a sentence, according to new research.

Replacing coal with natural gas would reduce global warming

Replacing coal with natural gas would reduce global warming: A debate has raged in the past couple of years as to whether natural gas is better or worse overall than coal and oil from a global warming perspective. The back-and-forth findings have been due to the timelines taken into consideration, the details of natural gas extraction, and the electricity-generating efficiency of various fuels. A new analysis which focuses exclusively on potential warming and ignores secondary considerations, such as economic, political, or other environmental concerns, finds that natural gas is better for electricity generation than coal and oil under all realistic circumstances.

How the Navy's Incompetence Sunk the 'Green Fleet'

How the Navy's Incompetence Sunk the 'Green Fleet': On Wednesday, the Navy will sail its eco-friendly "Great Green Fleet" for the first time -- and maybe the last. The Navy has screwed up its once-promising biofuel plan with a blend of bad politics and questionable analysis, alienating Congress and Pentagon insiders alike. And that's before they get socked with a $1.8 billion annual bill for all that green fuel.

Man Physically Assaulted At McDonald's For Wearing Digital Eye Glasses

Man Physically Assaulted At McDonald's For Wearing Digital Eye Glasses:



RockoW writes "Steve Mann, a long-time researcher of computer vision systems, (i.e. Augmented reality, Digital Eyeglass) had an incident at a McDonald's in Paris, France. He was assaulted by three men during his visit to get food with his family. They had a problem with his digital eye glasses and tried to take them off his head. 'The eyeglass is permanently attached and does not come off my skull without special tools.' The men also tore up Mann's documentation and a letter from his doctor explaining the device's use. Fortunately, the rough treatment of the device caused it to keep recent images in its memory, instead of quickly overwriting them, so Dr. Mann has pictures of the men who assaulted him."
