  • @Detry 10…9…

    I was asked a couple years ago what’s keeping us from having walking, talking robots that can at least pass as human to a drunk guy, this is the tech that I named. I figured we’d have good language and voice models by then (and we pretty much do), but the movement of biological systems is really hard to emulate with servos or other actuators. Muscles have the quality where they get thicker as they get shorter and can do so continuously. That goes a long way to making a face move in a realistic way.

    We’ve had artificial muscles for some time, but they either require high energy, need to get hot to contract (and are therefore slow to cycle), or require dangerously high voltages. This one solves the high voltages problem by going miniature. You can get the high fields you need in much smaller voltages that way. It’s still early days, but this could be a game changer.


  • This seems like a poorly designed experiment to me. People providing partial information about a word that’s “on the tip of their tongue,” would be expected to make wrong guesses. If they could make the right guesses, then there are good odds that they would be able to reconstruct/recollect the word. You could just as easily interpret this as the word having been “misfiled” so that its recall is blocked by incorrect information associated with it.

    I get TOT far more often than I would like, but there’s almost always a word that I get to eventually.









  • @Girlparts Can somebody get the the original paper and report on what concentration they were using. Whenever I’ve compared lab results with environmental measurements, the labs are using >1,000,000-fold higher concentrations of particles to get a response. It’s never immediately obvious because the two kinds of studies typically use different units.

    The other question I have is the particle size. Their largest particles in the study are 1µm. That’s generally the smallest that I’ve been able to find reported in environmental measures. Either it’s just not possible to detect unlabelled particles smaller than that (which as an analytical chemist, I doubt), or particles at that size range break down quite quickly do the exponentially increasing surface area/volume ratio. If anyone has links to papers that look that far down the size scale, I’d appreciate them.
