  • With my printer, I certainly couldn't print nm features, and as it decayed, they'd open up anyway. Home 3D printers are more on the 0.5mm resolution level. I'd be going more for a bulk object, just solid material that released as it dissolved, …
  • There are fictional vampires in the Blindsight/Echopraxia universe (By Peter Watts, highly recommended, especially for the sort of people on this forum). It has a scientific explanation for their repulsion by crucifixes, and the fact that we think t…
  • I ran across a write-up of a very early version of that glove that was being developed with, if I remember correctly, DARPA funding. The goal was to have a device that was wearable by an active user in extreme heat or cold, and while it may have bee…
  • I get the impresson that what Finn333 is talking about is, essentially, being really good at paying attention. If you're aware of what's going on around you, you can predict the future. Most people have probably done this already: you watch your cat…
  • "It's entirely possible that a large amount of technical and machinery-centric jobs could start requiring augmentation for workers to keep up -- how is that going to factor into society?" It arguably already is, and has been. How many people get …
  • If I had to guess, my projection for the future of humanity is this: We'll finish disconnecting sex from reproduction, and (hopefully) get our society to a place where participation in both, either, or neither is voluntary. One of these is likely …
  • @Cassox If you do enough salvia, the disturbing things are on the inside of your eyelids.
  • Ecdysterone isn't known to do anything in humans, but I do admire the "WOO! Eat three grams of insect hormones! WOO!" kind of... gonzoness about this plan.
  • The color distortion in CRTs is because a magnetic field will deflect the electron beam, and, if you're unlucky, magnetize the shadow mask so that it stays deflected. LCDs don't have a shadow mask, electron beam, etc, and so are immune. Source: I …
  • @teddythetwig I've had cell phones mess up hotel cards. Probably not the radios, but when it spins up the little motor to vibrate the phone. A neodymium magnet will certainly do it. The difference is coercivity, which is how strong a magnetic fiel…
  • This is what I was cautioning against when I said "if someone is attacking you with a TASER, they're not likely to give up if it fails". The police will not go "Oh, he's shielded. Lets pack it up and go home, lads." If you're in the US, they will …
  • http://lessemf.com/ You can get a lot of very conductive fabrics there, stuff well under 1Ohm/sq ft. Some of it even looks pretty normal, so the outfit wouldn't be weirdly thick or padded looking. Of course, if someone is attacking you with a TAS…
  • Radiation poisoning is more from acute doses (criticality incidents, Russians served you polonium in your tea) than from e.g. lantern mantle ash in your salt shaker. But of course, any dose small enough to have minimal or unnoticed side effects migh…
  • Electrical stimulation also recruits fibers in the opposite order from recruitment under neurological control (although there's some debate about this). I'm not sure it matters for power output, but it does for fatigue. I suspect one set of the Mu…
  • Yeah, anything with small radioactive particles in it, like a suspension of finely ground thorium (from e.g. lantern mantles if you want to DIY it) Hopefully some of the particles end up decaying and triggering a mutation that leads to cancer. The…
  • @nat, if you're a collegiate athlete involved in any officially sanctioned and scored sport, you probably have some governing body that restricts what you're allowed to take. If you're not, their banned chemical list is probably a great place to s…
  • The reputable vendors have independent CoA (Certificate of Analysis, if I remember correctly) that they will send you a copy of. The Nootropics subreddit /r/Nootropics has some information on that process, and I added a couple of suppliers I use (an…
  • Like you say: without ingesting too much. Start with a very small amount, less than whatever is an active dose, and see how you react. Gradually increase the dose until you either reach the active dose or have an adverse reaction. The only nootrop…
  • Sorry about the thread necromancy, but this seems to be the main place to chat about magnetic tattoo ink. Turns out, you can get ferromagnetic particles in a tattoo to interact with a magnetic field, and if the magnetic field is big enough, it suc…
