The Future is Here: DARPA’s Nervous System Implants

DARPA_implantHard on the heels of their proposed BRAIN initiative – a collaborative research initiative to map the activity of every neuron in the human brain – DARPA has announced a bold new program to develop tiny electronic implants that will be able to interface directly with the human nervous system to control and regulate many different diseases and chronic conditions, such as arthritis, PTSD, Crohn’s disease, and depression.

The program, called ElectRx (pronounced ‘electrics’), ultimately aims to replace medication with “closed-loop” neural implants which monitor the state of your health and then provide the necessary nerve stimulation to keep your organs and biological systems functioning properly. The work is primarily being carried out with US soldiers and veterans in mind, but the technology will certainly percolate down to civilians as well.

electrx-darpaThe ElectRx program will focus the relatively new area of medical therapies called neuromodulation, which seeks to modulate the nervous system to improve neurological problem. Notable examples of this are cochlear implants which restore hearing by modulating your brain’s auditory nerve system, and deep brain stimulation (DBS) which is apparently capable of curing/regulating conditions  like depression and Parkinson’s by overriding erroneous neural spikes.

So far, these implants have been fairly large, which makes implantation fairly invasive and risky. Most state-of-the-art implants also lack precision, with most placing the stimulating electrodes in roughly the right area, but which are unable to target a specific bundles of nerves. With ElectRx, DARPA wants to miniaturize these neuromodulation implants so that they’re the same size as a nerve fiber.

electrx-darpa-implant-diagramThis way they can be implanted with a minimally invasive procedure (through a needle) and attached to specific nerve fibers, for very precise stimulation. While these implants can’t regulate every condition or replace every medication (yet), they could be very effective at mitigating a large number of conditions. A large number of conditions are caused by the nervous system misfiring, like inflammatory diseases, brain and mental health disorders.

Currently, a variety of drugs are used to try and cajole these awry neurons and nerves back in-line by manipulating various neurotransmitters. However, the science behind these drugs is not yet exact, relying heavily on a trial-and-error approach and often involving serious side-effects. Comparatively, an electronic implant that could “catch” the misfire, cleans up the signal, and then retransmits it would be much more effective.

cochlear_implantAs DARPA’s Doug Weber explained:

The technology DARPA plans to develop through the ElectRx program could fundamentally change the manner in which doctors diagnose, monitor and treat injury and illness. Instead of relying only on medication — we envision a closed-loop system that would work in concept like a tiny, intelligent pacemaker. It would continually assess conditions and provide stimulus patterns tailored to help maintain healthy organ function, helping patients get healthy and stay healthy using their body’s own systems.

Despite requiring a lot of novel technological breakthroughs, DARPA is planning to perform human trials of ElectRx in about five years. The initial goal will be improving the quality of life for US soldiers and veterans. And while they have yet to announce which conditions they will be focusing on, it is expected that something basic like arthritis will be the candidate – though there are expectations that PTSD will become a source sooner other than later.

AI'sAnd this is just the latest neurological technology being developed by DARPA. Earlier in the year, the agency announced a similar program to develop a brain implant that can restore lost memories and experiences. A joint fact sheet released by the Department of Defense and the Veteran’s Association revealed that DARPA also secured 78 million dollars to build the chips as part of the government’s Brain Research through Advancing Innovative Neurotechnologies (BRAIN) program.

While DARPA’s ElectRx announcement is purely focused on the medical applications of miniature neural implants, there are of course a variety of other uses that might arise from elective implantation – for soldiers as well as civilians. With a few well-placed implants in a person’s spine, they could flip a switch and ignore any pain reported by your limbs, allowing them to withstand greater physical stress or ignore injuries.

posthumanImplants placed in muscle fibers could also provide added electrostimulation to provide extra boosts of raw muscle power. And With precision-placed implants around the right nerve fibers, people could gain manual control of their organs, allowing them to speed up or slow down their hearts, turbo-charge their livers, or tweak just about any other function of their bodies.

The age of the Transhuman looms, people!

The Future is Here: MMI Electronic Tattoos!

patchIt’s known as Mind-Machine-Interface, the ability to interface and control machines using only your mind. And thanks to a number of dedicated researchers in various fields, it’s no longer the stuff of science fiction. With mind-controlled prosthetics, bionic limbs, and the growing field of machine-enabled telepathy, the day may soon come when people can interface, access and control machinery with just a few thoughts.

But of course, that raises all kinds of concerns about invasive procedures, whether surgery will be needed in order to implant devices into the human brain that can translate brainwaves into commands. Alternately, where non-invasive means are involved, it can take some time to calibrate the machinery to respond to the user’s nerve impulses. As those awful infomercials say, “there has be a better way!”

patch_headAs it turns out, electrical engineer Todd Coleman and his team at the University of California at San Diego has been working on a way to use wireless flexible electronics that one can apply on the forehead just like temporary tattoos. Building on the emerging field of biomedical electronics, these tattoos will be able to read brainwaves and allow a person to control electronic devices without the need for surgery or permanent implants.

The devices are less than 100 microns thick, the average diameter of a human hair, and consist of circuitry embedded in a layer or rubbery polyester that allow them to stretch, bend and wrinkle. The devices can detect electrical signals linked with brain waves and incorporate solar cells for power and antennas that allow them to communicate wirelessly or receive energy.

patch_breakdownOf course, other elements can be added as well, like thermal sensors to monitor skin temperature and light detectors to analyze blood oxygen levels, making it both a health monitoring patch and a fully-integrated control device. Combined with health patches that are being developed for use internally, an entire health network can be created that allows for every aspect of a patients health to monitored in real-time, anticipating and predicting health problems before they flare up.

Currently, Coleman and his colleagues are pursuing the application of using these patches to monitor premature babies to detect the onset of seizures that can lead to epilepsy or brain development problems. The devices are also being commercialized for use as consumer, digital health, and medical device. But the potential for their use is staggering, even alarming.

droneFor example, these devices can also be put on other parts of the body, such as the throat. When people think about talking, their throat muscles move even if they do not speak, a phenomenon known as subvocalization. Electronic tattoos placed on the throat could therefore behave as subvocal microphones through which people could communicate silently and wirelessly to each other.

However, a more alarming application is in the industrial and defense field, which is being pursued by the startup MC10 in Cambridge, Mass. In the course of their research, Coleman and his colleagues found that individuals who were hooked up to a computer through large caps studded with electrodes were able to remotely control airplanes and a UAV over cornfields in Illinois. Such is not possible with these tattoos at present, but Coleman admits that he and his colleagues are “working on it”.

telepathyBut even more alarming than this is the long term implications of what this could mean for us as a species, which is that electronics could one-day enable wireless peer-to-peer brain communication – aka. machine-enabled telepathy. With devices that can read and transmit brainwaves and vocal information, it would no longer be necessary for people to use radios, phones, email, or any other means of communication to talk to one another.

Simply tune in, subvocalize or think what you want to convey – and boom! instant messaging and perfected! Lord knows the art of diplomacy might suffer, and we can forget about sarcasm, tact, or shades of meaning. Society may very well breakdown or people will just have to grow thicker skin as everyone is forced to communicate what they really think to each other!

The Future is Here: Brain to Brain Interfaces!

?????????????????And I thought the month of February was an already exciting time for technological breakthroughs! But if a recent report from Nature.com is any indication, February will go down in history as the biggest month for breakthroughs ever! Why just last week, researchers in Natal, Brazil created the first ever electronic link between the brains of two living creatures.

The creatures in question were rats, and the link between their brains enabled one to help the other solve basic puzzles in real time — even though the animals were separated by thousands of kilometers of distance. The experiment was led by Miguel Nicolelis of Duke University, a pioneer in the field of brain-machine interfaces (BMIs), and a team of neurobiologists who’ve been working in the field for some time.

BMIHere’s how it works: An “encoder” rat in Natal, Brazil, trained in a specific behavioral task, presses a lever in its cage which it knows will result in a reward. A brain implant records activity from the rat’s motor cortex and converts it into an electrical signal that is delivered via neural link to the brain implant of a second “decoder” rat. The second rat’s motor cortex processes the signal from rat number one and – despite being thousands of km away and unfamiliar with what rat one is up to — uses that information to press the same lever.

MMIBack in 2011, Nicolelis and his colleagues unveiled the first such interface capable of a bi-directional link between a brain and a virtual body, allowing a monkey to not only mentally control a simulated arm, but receive and process sensory feedback about tactile properties like texture. And earlier this month, his team unveiled a BMI that enables rats to detect normally invisible infrared light via their sense of touch.

However, this latest experiment really takes the cake. Whereas brain-machine interfaces have long been the subject of research, generally for the sake of prostheses, a brain-to-brain interface between two living creatures in something entirely new, especially one that enables realtime sharing of sensorimotor information. And while it’s not telepathy, per se, it’s certainly something close, what Nicolelis calls “a new central nervous system made of two brains.”

Obviously, this kind of breakthrough is impressive in its own right, but according to Nicolelis, the most groundbreaking application of this brain-net (or n-mind) is yet to come:

These experiments demonstrated the ability to establish a sophisticated, direct communication linkage between rat brains, so basically, we are creating an organic computer that solves a puzzle. We cannot predict what kinds of emergent properties would appear when animals begin interacting as part of a brain-net. In theory, you could imagine that a combination of brains could provide solutions that individual brains cannot achieve by themselves.

neural-networksNaturally, there are some flaws in the process, which were made evident by the less-than-perfect results. For starters, the untrained decoder rats receiving input from a trained encoder only chose the correct lever around two-thirds of the time. Those results could not be the result of random odds, but they are also a far cry from the 95% accuracy where the signals were reversed, going from the untrained decoder to the trained encoder. As any student of science knows, one-way results are not the basis of a sound process.

And I imagine the people who are lobbying to make biosoldiers illegal and limit the use of autonomous drones will be on this like white on rice! Hence why we can probably look forward to many years of research and development before anything akin to human trials or commercial applications of this technology seem realizable.

And of course, there is a video demonstrated the mind link at work. a word of warning first though. If you’re an animal lover, like me, the video might be a little difficult to take. You be the judge:

Controlling Epilepsy with Lasers

optogenetics-640x353For over a century, scientists have sought to learn more about epilepsy, the most common form of seizure activity in humans. Basically, these seizures are what happen when neurons misfire in response to sudden exposure to light. Arising in discrete regions on either pole of the brain, this neurological disorder effects many people worldwide and can have a drastic impact on their lives. Luckily, it seems that researchers may finally have a way to predict the seizures and even eliminate them  altogether.

It’s called optogenics: the science of using genetically modified viruses to insert light-responsive channels into the neurons and then following that up with the use of lasers to reduce and even eliminate TLE, or temporal lobe epilepsy. And thanks to ongoing research, there might just be a way to both predict and shut down these episodes of unwanted neurological activity just as they begin. And ironically, its all through the use of targeted laser light.

Mouse-HippocampusThe breakthrough came in a recent study by Nature Communications, researchers were able to trigger seizures in mice by treating the hippocampus section of their brains (the part involved in seizure activity). It began with the use of an acid named kainate that is derived from seaweed, which in turn left them susceptible to spontaneously generated seizure activity. Then, through the use of a series of implanted EEG electrodes, the researchers were able to detect signs that seizures were beginning and then shut them off with light.

Naturally, there are concerns about adapting the technique to humans. Not only were the mice specifically engineered for the study, there is also the issue of achieving full optical stimulation in human subjects. To address these issues, a number of solutions are in the works. For example, biocompatible polymer electrodes have been designed to ensure that the genetically-modified virus can be delivered properly to the human brain. In addition, a number of key developers have been working on compact devices that contain hundreds of discrete delivery electrodes that ought to provide the requisite neurological stimulation.

neurozeneIt is research, and it’s ongoing. But the results are encouraging and with ongoing development to adapt it to humans, anti-seizure medical devices are expected to be exploding in the near future. Much like the tiny electrodes used to stimulate brain activity and recollection in a simian, we could be looking at the prototype for a new type of brain implants that addresses and eliminates neurological disorders.

Top Stories of 2012

biotech_alienAs Dec. 31st fast approaches, I find myself thinking about New Years resolutions. And part of that is taking stock on what’s been accomplished in the past year. For me, one of those resolutions was to stay current and share all the new and exciting news from the field of science and tech all my followers people; to the best of my abilities, that is.

In keeping with this, I wanted to create a list of the most important developments of the last year. Many sites have produced a top 10, top 12, even a top 7, list of what they thought the most significant accomplishments were. Well, I wanted to do one of my own! Opinion varies as to what the biggest leaps and bounds were over the course of the last year, and I’ll be damned if I don’t get my say in. Lord knows I’ve spent enough time reading about them, so here’s my comprehensive list of the greatest inventions, developments and advances made during 2012.

I think you’ll all agree, the list packed with stories that are intriguing, awe-inspiring, and even a little scary! Here are the top 12, as selected by me, in alphabetical order:

3D Printing:
cartilage1As far as tech trends go, this one has been in the works for some time. However, 2012 will be remembered as the year that 3D printing truly became a reality. From tree-dimensional models to consumer products to even guns, 3D printers have been featured in the news many times over for their potential and frightening abilities.

However, one of the greatest potential uses will be in the field of artificial cartilage, organs, and even food. As the technology is refined and expands to the field of organic molecules, just about anything can and will be synthesized, leading to an era where scarcity is… well, scarce!

Bionic Implants:
mindcontrolledprostheticPerhaps the years biggest achievement came in the form of bionic prosthetics, artificial limbs which are calibrated to respond to the nerve impulses of the user. As a result, amputees, veterans and accident victims are able to receive artificial limbs that act like the real thing.

The most notable case was Zak Vawter who scaled the 103 flights of Chicago’s Willis Tower using an artificial leg. In addition, two men in Britain had their sight restored after undergoing the first ever case of retinal surgery where bionic implants were placed in their eyes.

Brain Implants:
digital-mind1In September of 2012, scientists grafted an implant onto the brain of Chimpanzee, enhancing its brain power by ten percent. This consisted of an electrode array that was attached to the cerebral cortex of several monkey subjects, researchers were able to restore and even improve their decision-making abilities.

The implications for possible therapies is far-reaching, such as with brain injuries and cognitive disorders. But additionally, it also heralds the beginning of an era where human beings will be able to enhance their intelligence, recall, and memory retention.

Commercial Space Flight:
skylonThough not yet fully realized, 2012 was a big year in terms of commercial space flight. For example, Richard Branson and Virgin Galactic announced the first successful fully-loaded “glide test” of SpaceShipTwo, the rocket craft that will be taking passengers into low orbit as soon as all the kinks are worked out of the design.

In addition, Reaction Engines announced a breakthrough with the design of their hypersonic engine, which they claim will be fitted to their proposed spaceship – the Skylon. Capable of achieving speeds of up to Mach 5, this new craft is expected to be able to take off from conventional airfields, propel itself into low orbit, and deliver supplies to the ISS and make commercial trips around the world. No telling when either company will be conducting its first real suborbital flights, but the clock is ticking down!

Curiosity Rover:
Curiosity_selfportraitOne of the years biggest announcement was the deployment of the Curiosity Rover on the Martian surface. Since it landed, the rover has provided a constant stream of scientific updates and news on the Red Planet. Though the Mars Science Team did not find the “earthshaking” proof organic molecules, it did make a number of important discoveries.

Amongst them was solid evidence that Mars was once home to large rivers and bodies of water. Furthermore, the x-ray lab on board the rover conducted studies on several rock and soil samples, determining what the chemical and mineral composition of Mars surface is.

Faster-Than-Light Travel:
alcubierre-warp-drive-overviewIn the course of speaking at the 100 Year Starship, scientists at NASA began working on the first FTL travel system ever. Long considered to be the stuff of science fiction, physicist Harold White announced that not only is the math sound, but that his team at NASA had actually started working on it.

Relying on the concept of the Alcubierre Drive, the system involves expanding and contracting space time around the ship, allowing it to move faster than the speed of light without violating the Law of Relativity.

Geo-engineering:
converted PNM fileIn October, the world’s first – and illegal – act of geo-engineering took place off Canada’s West Coast. The product of a “rogue geohacker” named Russ George, who was backed by a private company, the project involved the dumping of around 100 tonnes of oron sulphate into the Pacific Ocean. This technique, known as ocean fertilization, was meant to stimulate the growth of algae which metabolize carbon and produce oxygen.

The experiment, which is in violation of two United Nations moratoria, outraged many environmental, legal, and civic groups, many of whom hail from Haida Gwaii, the traditional territory of the Haida nation, who had enlisted by George as part of a proposed “salmon enhancement project”. Though illegal and abortive, the act was the first in what may very well become a series of geoengineering efforts which will be performed the world over in order to stay the progress of Climate Change.

Google’s Project Glass:
google_glasses2012 was also the year that augmented reality became… well, a reality (oh dear, another bad pun). Back in April, Google unveiled its latest concept device for wireless and portable computing, known as Project Glass. Combining an active display matrix, a wireless internet connection and a pair of shades, Google managed to create a device that looks like something straight out of cyberpunk novel.

HIV and Flu Vaccines:
HIV-budding-ColorWhen it comes to diseases, HIV and the Flu have two things in common. Until 2012, both were considered incurable, but sometime in the near future, both could be entirely preventable. In what could be the greatest medical breakthroughs in history, 2012 saw scientists and researchers experiment with antibodies that have been known to fight off HIV and the flu, and to good effect.

In the former case, this involved using a new process known as Vectored ImmunoProphylaxis (VIP), an inversion of the traditional vaccination method, where antibodies were introduced to mice. After allowing the antibodies to reproduce, researchers at Caltec found that the mice were able to fight off large quantities of the virus. In the latter, researchers at the Friedrich-Loeffler Institute in Riems Island, Germany used a new RNA-based vaccine that appeared to be able to fight off multiple strains of flu, not just the latest mutation.

Taken together, these vaccines could bring an end to a common, but potentially deadly ailment, and signal the end of the plague of the 20th century. In addition, this could be the first in a long series of developments which effectively brings all known diseases under our control.

Medical Implants:
enhancement2012 also saw the culmination of several breakthroughs in terms of biomedical research. In addition to the world’s first medimachine, there were also breakthroughs in terms of dissolving electronics, subdermal implants that dispense drugs, and health monitoring patches.

Little wonder then that Cambridge University announced the creation of the Center for the Study of Existential Risk to evaluate future technologies, or that Human Rights Watch and Harvard University teamed up to release a report calling for the ban of “killer robots”. With all the potential for enhancement, it could be just a matter of time before non-medical enhancements are a reality.

Mind-controlled prostheses:
woman-robotic-arm_650x366Researchers at BrainGate created a brain-machine interface that allows users to control an external device with their minds. The first person to use this revolutionary new system was Cathy Hutchinson, a stroke victim who has been paralyzed from the neck down for 15 years, who used the robotic arm to drink a cup of coffee.

This news, combined with other advances in terms of bionic prostheses, could signal the end of disability as we know it. Henceforth, people with severe injuries, amputations and strokes could find themselves able to make full recoveries, albeit through the use of robotic limbs.

Self-driving cars:
googlecar2012 marked an important year as three states (California, Nevada, and Florida) made autonomous vehicles legal. Self-driving cars, once perfected and produced en masse, will help with traffic congestion and significantly reduce the chance of auto accidents through the use of GPS, radar, and other technologies.

*               *               *

All in all, it’s been an exciting year. And with all that’s been accomplished, the future is certainly looking a lot more interesting and even frightening. What is clear is that predictions made for some time now are becoming realizable, including replication, a cure for all known diseases, advanced robotics, implants, cybernetics, and even post-humanism. Regardless of where one sits on these developments, be you pro, con, or neutral, I think we can all agree that it is an exciting time to be alive!

Happy New Year to all, and here’s hoping 2013 proves just as interesting, and hopefully a lot more peaceful and sound. And may we ALL find ourselves able to keep our New Years resolutions and build upon all we’ve accomplished so far. And of course, with all the potential for medical and technological enhancements that are coming, I sincerely hope we can find ways to improve ourselves on a personal level too!

Transhumans by 2030?

transhumanismThe issue of transhumanism, the rise of a new type of humanity characterized by man-machine interface and augmented intelligence, is being debated quite fervently in some circles right now. But it seems that groups other than Futurists and speculative fiction writers are joining the discussion. Recently, the National Intelligence Council, a US policy think-tank, released a 140 page report that outlined major trends and technological developments we should expect in the next 20 years.

The report, entitled “Global Trends 2030: Alternative Worlds”, predicted several trends which are likely to come true in the near future. Amongst them is the end of U.S. global dominance, the rising power of individuals against states, a growing middle class that will increasingly challenge governments, and ongoing shortages in water, food and energy. However, predictions were also made concerning a future where humans have been significantly modified by various technologies, what is often referred to as the dawn of the Transhuman Era.

how-nanotechnology-could-reengineer-usIntrinsic to this new era is the invention of implants, prosthetics, and powered exoskeletons which will become regular fixtures of human life. These will go beyond merely correcting for physical disabilities or injury, to the point where average humans are enhanced and become more productive. 2030 is key year here, because it is by this point that the authors predict that prosthetics will exceed organics, and people will begin getting them installed in order to augment themselves.

In addition, life extension therapies and medical advances which will be used predominantly by the elderly will become a means for otherwise healthy people to prolong their lives and maintain health and vitality for longer periods of time. Brain implants are expected to become a reality as well, ostensibly to allow people to have brain-controlled prosthetics, but also for the sake of enhanced memory and augmented thinking.

bionic_handAnd of course, bionics are an important factor in all this. Already, researchers have achieved breakthroughs with bionic limbs, but retinal attachments, artificial eyes, and even fully-functioning organs are expected before 2030. On top of that, improvements in drugs, such as neuropharmaceuticals – drugs that enhance memory, attention, speed of thought – and implants which assist in their delivery are expected to be making the rounds.

google_glassesFinally, there is the matter of virtual and augmented reality systems, which are already becoming a reality thanks to things like Project Glass and recent innovations in PDAs. As the report notes: “Augmented reality systems can provide enhanced experiences of real-world situations. Combined with advances in robotics, avatars could provide feedback in the form of sensors providing touch and smell as well as aural and visual information to the operator.”

However, the big issue, according to the report, is cost and security. Most of these technologies will be not affordable to all people, especially for the first few years of their existence. This could result in a two-tiered society where the well-to-do live longer, healthier and have a competitive advantage over “organics”, people of lesser means who are identifiable by their lack of enhancements. Also, developers will need to be on their guard against hackers who might attempt to subvert or infect these devices with tailor-made viruses.

Naturally, the importance of maintaining uniform scientific progress was stressed, and the need for a regulatory framework is certainly needed. What the CSER recently recommended is certainly worth keeping in mind here, which was to ensure that some kind of regulatory framework be put in place before all of this becomes a reality. What’s more, public education is certainly necessary, so that the current and next generation of human beings knows what to expect and how to go about making informed choices therein.
