MIT Creates Glucose Fuel Cell To Power Implanted Brain-Computer Interfaces

MrSeb writes "Neuroengineers at MIT have created an implantable fuel cell that generates electricity from the glucose present in the cerebrospinal fluid that flows around your brain and spinal cord. The glucose-powered fuel cell is crafted out of silicon and platinum, using standard semiconductor fabrication processes. The platinum acts as a catalyst, stripping electrons from glucose molecules, similar to how aerobic animal cells (such as our own) strip electrons from glucose with enzymes and oxygen. The glucose fuel cell produces hundreds of microwatts (i.e. tenths of a milliwatt), which is a surprisingly large amount — it comparable to the solar cell on a calculator, for example. This should be more than enough power to drive complex computers — or perhaps more interestingly, trigger clusters of neurons in the brain. In theory, this glucose fuel cell will actually deprive your brain of some energy, though in practice you probably won't notice (or you might find yourself growing hungry sooner)."

    Nearly four months ago, I noticed that my internet connection was very sluggish. Eventually getting fed up with it, I began to seek out software that would speed up the gigabits in my router. After an hour of searching, I found what at first appeared to be a very promising piece of software. Not only did it claim it would speed up my internet connection, but that it would overclock my power supply, speed up my gigabits, and remove any viruses from my computer! "This is a fantastic opportunity that I simply can't pass up," I thought. I immediately downloaded the software and began the installation, all the while laughing like a small child. I was highly anticipating a future where the speed of my internet connection would leave everyone else's in the dust.

    I was horribly, horribly naive. Immediately upon the completion of the software's installation, various messages popped up on my screen about how I needed to buy software to remove a virus that I wasn't aware I had from a software company I'd never once heard of. The strange software also blocked me from doing anything except buying the software it was advertising. Being that I was a computer whiz (I had taken a computer essentials class in high school that taught me how to use Microsoft Office, and was quite adept at accessing my Facebook account), I was immediately able to conclude that the software I'd downloaded was, in fact, a virus, and that it was slowing down my gigabits at an exponential rate. "I can't let this insanity proceed any further," I thought.

    As I was often called a computer genius, I was confident at the time that I could get rid of the virus with my own two hands. I tried numerous things: restarting the computer, pressing random keys on the keyboard, throwing the mouse across the room, and even flipping an orange switch on the back of the tower and turning the computer back on. My efforts were all in vain; the virus persisted, and my gigabits were running slower than ever! "This cannot be! What is this!? I've never once seen such a vicious virus in my entire life!" I was dumbfounded that I, a computer genius, was unable to remove the virus using the methods I described. Upon coming to terms with my failure, I decided to take my computer to a PC repair shop for repair.

    I drove to a nearby computer repair shop and entered the building with my computer in hand. The inside of the building was quite large, neat, and organized, and the employees all seemed very kind and knowledgeable. They laughed upon hearing my embarrassing story, and told me that they saw this kind of thing on a daily basis. They then accepted the job, and told me that in the worst case, it'd be fixed in three days from now. I left with a smile, and felt confident in my decision to leave the computer repairs to the experts.

    A week later, they still hadn't called back. Visibly angry, I tried calling them countless times, but not a single time did they answer the phone. Their negligence and irresponsibility infuriated me, and sent me into a state of insanity that caused me to punch a gigantic hole in the wall. Being that I would require my computer for work soon, I decided to head over to the computer repair shop to find out exactly what the problem was.

    Upon entering the building, I was shocked by the state of its interior; it looked as if a tornado had tore through the entire building! Countless broken computers were scattered all about the floor, desks were flipped over, the walls had holes in them, there was a puddle of blood on the floor, and worst of all, I saw that my computer was sitting in the middle of the room laying on its side! Absolutely unforgivable! I soon noticed one of the employees sitting behind one of the tipped over desks (the one that had previously had the cash register on top of it); he was shaking uncontrollably and sobbing. Despite being furious about my computer being tipped over, seeing him in that state still managed to make me less unforgiving. I decided to ask him what happened.

    About eight months ago, I was searching around the internet to find out why my computer was running so slowly (it normally ran quite fast, but had gradually gotten slower over time). After a few minutes, I found a piece of software claiming that it could speed up my PC and make it run like new again. Being that I was dangerously ignorant about technology in general (even more so than I am now), I downloaded the software and began the installation. Mere moments after doing so, my desktop background image was changed and warnings that appeared to originate from Windows appeared all over the screen telling me to buy strange software from an unknown company in order to remove a virus it claimed I had.

    I may have been ignorant about technology, but I wasn't that naive. I immediately concluded that the software I'd downloaded was, in fact, a virus. In my rage, I broke numerous objects, punched a hole in the wall, and cursed the world at the top of my lungs. I eventually calmed down, cleared my head, and realized that the only remedy for this problem was a carefully thought out plan. After a few moments of pondering about how to handle this situation, I decided that since I barely knew how to properly handle a computer, I should turn it over to the professionals and let them fix the issue.

    Soon after making the decision, I drove to a local computer repair shop and entered the building with my computer in hand. They greeted me with a smile and stayed attentive the entire time that I was explaining the problem to them. They laughed as if they'd heard it all before, told me that I'm not the only one who has trouble operating computers, and then gave me a date for when the computer would be fixed. Not only had they told me that the computer would be completely repaired in at most two days, but the price for their services was surprisingly low, and to top it all off, they even gave me advice for how to avoid viruses in the future! I left the building feeling confident in my decision to seek professional help and satisfied knowing that such kind-hearted people were the ones doing the job.

    The very next day, I received a phone call from the computer repair shop whilst I was at a local library researching computer viruses. I had stumbled upon a piece of software that appeared to be very promising, and I was about to do more research on it, but seeing as how I required my computer as soon as possible, I decided to put the matter on hold. Upon answering the phone and cheerfully greeting the person on the other end, I was greeted with a high-pitched shriek. Startled, I asked what was wrong. A few moments passed where nothing was said, and suddenly, the person on the other end said to me, in a low voice oozing with paranoia, "Come pick up your computer." They hung up immediately after saying that, and I couldn't help but notice that they sounded as if they were on the verge of tears. I briefly wondered if it was due to stress from work, and then drove to the computer repair shop to acquire my computer.

    I was positively dismayed upon entering the building. The inside of the computer repair shop looked nothing like the image from my memories. There were broken computer parts scattered throughout the room, ceiling tiles all over the floor, blood splattered in every direction I looked, and even a human toe on the ground. After processing this disturbing information, I began panicking and frantically looking around for my computer. I spotted an employee covered in blood sitting up against the wall, and noticed that his wrists had been slashed open. Thinking quickly, I ran up to him, grabbed him by the collar of his shirt, shook him around, and began screaming, "Where is it!? Where is my computer!?" After a moment of silence, he passed away, completely shattering my expectations. Such a thing! "What a meaningless individual," I thought.

    Enraged, I tore the building up even further than it already had been in my desperate search for my computer. Eventually I discovered a door leading to an area that was normally o

    Around a year ago, I was mindlessly surfing the internet (as I often do) when I came across an enigmatic web page. The page, which looked like a warning from my web browser, informed me that I had a virus installed on my computer and that to fix it, I should install a strange anti-virus program that I'd never heard of (which I found peculiar considering the fact that I already had anti-virus software installed on my computer). Despite having reservations about installing it, I did so anyway (since it appeared to be a legitimate warning).

    I cannot even fathom what I was thinking at that time. Soon after attempting to install the so-called anti-virus software, my desktop background image changed into a large red warning sign, warnings about malware began making appearances all over the screen, and a strange program I'd never seen before began nagging me to buy a program to remove the viruses. What should have been obvious previously then became clear to me: that software was a virus. Frustrated by my own stupidity, I began tossing objects around the room and cursing at no one in particular.

    After I calmed down, I reluctantly took my computer to a local PC repair shop and steeled myself for the incoming fee. When I entered, I noticed that there were four men working there, and all of them seemed incredibly nice (the shop itself was clean and stylish, too). After I described the situation to them, they gave me a big smile (as if they'd seen and heard it all before), accepted the job, and told me that the computer would be working like new again in a few days. At the time, I was confident that their words held a great degree of truth to them.

    The very next day, while I was using a local library's computer and browsing the internet, I came across a website dedicated to a certain piece of software. It claimed that it could fix up my PC and make it run like new again. I knew, right then, merely from viewing a single page on the website, that it was telling the truth. I cursed myself for not discovering this excellent piece of software before I had taken my PC to the PC repair shop. "It would've saved me money. Oh, well. I'm sure they'll get the job done just fine. I can always use this software in the future to conserve money." Those were my honest thoughts at the time.

    Two days later, my phone rang after I returned home from work. I immediately was able to identify the number: it was the PC repair shop's phone number. Once I answered, something strange occurred; the one on the other end of the line spoke, in a small, tormented voice, "Return. Return. Return. Return. Return." No matter what I said to him, he would not stop repeating that one word. Unsettled by this odd occurrence, I traveled to the PC repair shop to find out exactly what happened.

    Upon arriving inside the building, I looked upon the shop, which was a shadow of its former self, in shock. There were countless wires all over the floor, smashed computer parts scattered in every direction I looked, fallen shelves on the ground, desks flipped over on the ground, and, to make matters even worse, there was blood splattered all over the wall. Being the reasonable, upstanding, college-educated citizen that I was, I immediately concluded that the current state of the shop was due to none other than an employee's stress from work. I looked around a bit more, spotted three bodies sitting against the wall, and in the middle of the room, I spotted my computer. "Ah. There it is." Directly next to it was the shop's owner, sitting on the ground in the fetal position.

    When I questioned him, he kept repeating a single thing again and again: "Cannot be stopped! Cannot be stopped! Cannot be stopped!" I could not get him to tell me what was wrong, but after a bit of pondering, I quickly figured out precisely what happened: they were unable to fix my computer like they had promised. Disgusted by their failure, I turned to the shop's owner (who I now noticed had a gun to his head), and spat in his general direction. I then turned my back to him as
