  1. Because it's a solvable problem.

    02 March 2013

    There seem to be a couple of problems inherent in the tech field of prosthetic design. First and foremost of them is that comparatively few people need artificial limbs, so not enough of them are manufactured at once to bring the cost down. A second problem is that because so few people tend to need them, designs don't seem to improve very rapidly. When enough of anything are not constructed, there isn't enough pressure for bugs to be ironed out rapidly, nor for designs to evolve in positive directions so relatively simple advances may not appear soon. Business and industry …

  2. Outbreaks of the future: 3d printing.

    15 March 2012

    More and more in the year 2012 of the common era, I find myself noticing what Warren Ellis once called 'outbreaks of the future'. Advances and developments in technology that were once the thoughts of the dreamers of science and are now the fruits of the labor of shapers and makers of novel things. Perhaps it's due to my lack of 3d modeling ability that I tend to focus on the field of 3D printing, which has fascinated me since I helped build a 3d printer several years ago. So it goes.

    The first thing that I noticed was that …

  3. Programmable nanoprocessors and neural prosthetics?

    17 February 2011

    A dream many of us over the years had involve having head computers of one kind or another implanted. Augmentations of our existing capabilities, replacements for damaged sectors, direct neural interface with other computers, encrypted partitions for carrying data, brand new functionality - you name it, chances are there's a geek out there who'd love to beta test it. One of the problems at the moment, however, is a distinct lack of space inside the cranium. When you get right down to it there isn't a whole lot of wiggle room inside your skull. Layering circuitry on the surface of the …

  4. TSA at PHL raising eyebrows; travelers consider taking Amtrak.

    18 February 2010

    I've only been to Philadelphia a couple of times, all of them by driving to and from there. After reading about some of the stuff going on there not only do I not particularly want to visit that city, but I'm not entirely certain that I really want to fly again.

    This particular news story leaped out at me for its sheer WTF factor even though the incident seems to have taken place in March of 2009. Bob Thomas, a 53 year old Camden police officer, his wife Leona, and their four year old son Ryan were flying down to …

  5. On transhumanism.

    13 November 2009

    I've been wrestling with this post for weeks now because, at its heart, transhumanism isn't a simple set of beliefs, actions, or ideas. It encompasses many disciplines, from cybernetics to engineering to computer science to biology and many things in between. I say that not as a cop-out but because practically every discipline is covered in some way and informs the body of knowledge somehow. It is also a deeply personal philosophy, often attracting adherents who attempt to lead by example as well as participating in the research, development, and deployment of the technologies which originally inspired it (such as …

  6. Synthetic neurons on the horizon?

    16 July 2009

    Implants in the human brain can be called primitive when considered in light of the organ they are meant to interface with. While the state of the art in technology uses minute electrical impulses to communicate with groups of neurons within the brain, the brain itself goes far beyond mere patterns of electrical impulses. Modern science has confirmed the existence of several score of neurotransmitters, and there are probably more that haven’t been identified yet. I’m willing to bet that there are other mechanisms underlying the operation of the brain that I don’t even know about because …

  7. What hath the fabulists wrought?

    28 June 2009

    It’s long been said that science fiction predicts, or at least inspires some of the things which we take for granted every day. While the exact origins of the genre could be debated until the cows come home (and they most certainly are in some circles), it was some time during the 17th century c.e. during the Age of Reason in which people really began to write stories in which the advances of the time were their inspiration. Great voyages by sailing ship and fanciful aircraft were taken to regions of the globe which had only been seen …

  8. Not quite mind reading, not mind control the way people usually think of it, but significant nonetheless.

    05 October 2007

    At the Massachusetts Institute of Technology biotech researchers have made progress on an area of prosthetics that most people don't think about because it's so obvious but is still very important nonetheless: The neural interface. Specifically, they've worked out an algorithm that converts patterns of chemoelectrical activity in the brain that signify intent of motion into commands for an external device. Current prosthetics aren't directly hooked into the central nervous system but the "network edge" of the peripheral nervous system via interface jacks connected to nerve endings. Let's be clear, interface jacks that accept only broad sorts of input, such …

  9. From my alma mater, a monkey with a prosthetic arm.

    21 February 2007

    If you've been watching the Net for a while, you've probably heard about the monkey in a research lab at the University of Pittsburgh that has a prosthetic arm wired directly to its brain with an implanted interface. The monkey seems to have gotten pretty good with it, too - while restrained it can use the prosthetic arm to feed itself. If you follow the link to the neuro-bio lab you can even watch it in realtime.

  10. Retinal prostheses now being tested on felines.

    25 January 2007

    Prosthetic retinas are leaving the experimental stage and now are in live animal testing to shake the bugs out. A number of housecats with a condition similiar to retinitis pigmentosa, which causes blindness by killing the rod and cone cells that make up the retinas have been implanted with silicon chips 2mm on a side that replicate some of the functions of organic retinas. The chips are covered with microscopic photodiodes that register light levels, produce miniscule electrical impulses, and feed directly into the optic nerve. Similiar implants have been used in a small number of humans with this disorder …
