The Next Generation in Neural Prosthetics

The Next Generation in Neural Prosthetics | Jeff Morris | Scoop.it

Following up on the success of cochlear and retinal prostheses for people who have lost sensory function, neuroscientists see a limitless horizon for related devices that are able to read electrical and chemical signals from the nervous system to stimulate capability and restore quality of life in persons suffering injury and disease.

In the future, according to researchers, the devices – known as neural prosthetics – will help epileptics, persons with treatment-resistant depression and chronic pain, victims of Alzheimer’s disease, wounded war veterans suffering post-traumatic stress disorder and traumatic brain injury, persons with speech disabilities, and individuals who have sustained spinal cord injury and loss of limbs, among other applications in the research pipeline.

But before neural prosthetics can advance, engineers will be called on to make innovative use of materials to design and fabricate devices that allow sustained electronic functioning in the harsh environment of the human body, without causing tissue infection and other serious adverse conditions. Research efforts have focused on enhancing the performance of various types of materials used in neural prosthetics, in addition to developing interface technologies that enable the micro devices to be safely implanted in human tissue for long periods.

The monikers such as "deep learning" may be new, but Artificial Intelligence has always been the Holy Grail of computer science.  The applications are many, and the path is becoming less of an uphill climb.  

luiy's curator insight, February 26, 2014 6:19 AM

Deep learning itself is a revival of an even older idea for computing: neural networks. These systems, loosely inspired by the densely interconnected neurons of the brain, mimic human learning by changing the strength of simulated neural connections on the basis of experience. Google Brain, with about 1 million simulated neurons and 1 billion simulated connections, was ten times larger than any deep neural network before it. Project founder Andrew Ng, now director of the Artificial Intelligence Laboratory at Stanford University in California, has gone on to make deep-learning systems ten times larger again.

 

Such advances make for exciting times in artificial intelligence (AI) — the often-frustrating attempt to get computers to think like humans. In the past few years, companies such as Google, Apple and IBM have been aggressively snapping up start-up companies and researchers with deep-learning expertise. For everyday consumers, the results include software better able to sort through photos, understand spoken commands and translate text from foreign languages. For scientists and industry, deep-learning computers can search for potential drug candidates, map real neural networks in the brain or predict the functions of proteins.

Processors That Work Like Brains Will Accelerate Artificial Intelligence

Processors That Work Like Brains Will Accelerate Artificial Intelligence | Jeff Morris | Scoop.it

A new breed of computer chips that operate more like the brain may be about to narrow the gulf between artificial and natural computation—between circuits that crunch through logical operations at blistering speed and a mechanism honed by evolution to process and act on sensory input from the real world. Advances in neuroscience and chip technology have made it practical to build devices that, on a small scale at least, process data the way a mammalian brain does. These “neuromorphic” chips may be the missing piece of many promising but unfinished projects in artificial intelligence, such as cars that drive themselves reliably in all conditions, and smartphones that act as competent conversational assistants.

Incredibly Small 3D Printed Middle Ear Prosthesis is Achieved on a 3D Systems Printer

Incredibly Small 3D Printed Middle Ear Prosthesis is Achieved on a 3D Systems Printer | Jeff Morris | Scoop.it

3D printing has been providing various forms of prosthetic devices such as fingers, hands, arms and legs for a short time now, mostly due to the fact that it is affordable, easy to use, faster than traditional manufacturing, and provides for total customization. Companies are also really beginning to see the potential of 3D printing in the rapid prototyping of medical products.

 

One company, Potomac Laser, has been in the business of specializing in and creating medical devices, as well as other unique electronic devices for over 32 years now. Located in Baltimore, Maryland, they use 3D printing, laser micromachining, micro CNC and micro drilling in their many unique projects.

 

Just recently, a woman by the name of Monika Kwacz, who is a researcher at the Institute of Micromechanics and Photonics at Warsaw Technical University in Poland, contacted Potomac Laser to see if they could help her 3D print something almost unheard of. She had been studying stapedotomy, which is a form of surgical procedure that aims at improving hearing loss in those who suffer from the fixation of their stapes. The stapes, which is one of the 3 tiny bones within the middle ear involved in the conduction of sound vibrations to the inner ear, is the smallest and lightest bone within the human body.

 

Millions of peoples in the US alone suffer from a condition called Otosclerosis, where the stapes becomes stuck in a fixed position, and can no longer efficiently receive and transmit vibrations needed for a subject to hear properly. This is mostly due to a mineralization process of the bone and surrounding tissue.  It is estimated that 10% of the world’s adult Caucasian population suffers from this condition in one form or another.

How to put mirrors in space big enough to see continents and forests on exoplanets

How to put mirrors in space big enough to see continents and forests on exoplanets | Jeff Morris | Scoop.it

Shooting a laser at polystyrene beads, scientists have made a mirror that is held together by light. The creation could be a step towards putting ultra-light mirrors in space that would be big enough to see continents and forests on planets orbiting far-off stars.

 

Current space telescopes have limited vision because is it costly and complicated to send large, heavy mirrors into orbit. The mirror on NASA's premiere planet hunter, the Kepler space telescope, is just 1.4 metres across and cannot see planets directly. Instead Kepler spots the tiny changes in brightness when a world crosses in front of its host star.

 

When NASA's James Webb Space Telescope launches in a few years, it will carry the largest mirror yet into space: a 6.5-metre behemoth made of 18 interlocking segments. To fit into the launch vehicle, the mirror itself will have to be folded up and then unfolded in space.

 

Jean-Marc Fournier of the Swiss Federal Institute of Technology in Lausanne, Switzerland, and his colleagues have revived an old idea for building much larger mirrors by exploiting the force produced when laser beams hit tiny particles. Previous work has used this force to make optical tweezers, which can trap and manipulate a few particles at a time.

 

In 1979, astronomer Antoine Labeyrie, now at the Collège de France in Paris, suggested that the force could also trap a collection of particles into a flat plane to form a mirror. In theory, shooting two lasers at a central point should cause their optical forces to interfere, creating a stable region where particles line up to make a two-dimensional surface.

 

Such a mirror would be exceptionally light, relatively inexpensive and even self-repairing, as any particles knocked out by micro-meteors, which are constantly zipping through space, would simply be replaced by others nearby.

 

With funding from NASA's Institute for Advanced Concepts, Fournier's team took a first step towards this goal. They used a single laser to trap 150 micrometre-sized polystyrene beads against a sheet of glass (pictured). Light would normally bounce off a single bead in all directions, but grouping them together produces a flat reflective surface that acts exactly like a mirror, says Fournier.

 

To prove the mirror worked, the team shot light through a transparent ruler, so that it bounced off the beads and onto a detector. The resulting picture was murky, but they were able to make out an image of the number 8 on the ruler, which wasn't possible when the beads were removed from the glass.

Accidental discovery: 400-fold increase in electrical conductivity of a crystal through light exposure

Accidental discovery: 400-fold increase in electrical conductivity of a crystal through light exposure | Jeff Morris | Scoop.it
Quite by accident, Washington State University researchers have achieved a 400-fold increase in the electrical conductivity of a crystal simply by exposing it to light.

 

WSU doctoral student Marianne Tarun chanced upon the discovery when she noticed that the conductivity of some strontium titanate shot up after it was left out one day. At first, she and her fellow researchers thought the sample was contaminated, but a series of experiments showed the effect was from light. "It came by accident," said Tarun. "It's not something we expected. That makes it very exciting to share."

 

The phenomenon they witnessed—"persistent photoconductivity"—is a far cry from superconductivity, the complete lack of electrical resistance pursued by other physicists, usually using temperatures near absolute zero. But the fact that they've achieved this at room temperature makes the phenomenon more immediately practical.


And while other researchers have created persistent photoconductivity in other materials, this is the most dramatic display of the phenomenon. "The discovery of this effect at room temperature opens up new possibilities for practical devices," said Matthew McCluskey, co-author of the paper and chair of WSU's physics department. "In standard computer memory, information is stored on the surface of a computer chip or hard drive. A device using persistent photoconductivity, however, could store information throughout the entire volume of a crystal."
