  • 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, and possibly designed to be put in with a large needle.
  • 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 they're a legend now. The vampires are predators on humans. As predatory…
  • 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 been developed by a different group, used the exact same principle. The…
  • 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 eyeballing a picture frame that's on the counter with him and say "Don't…
  • "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 into nootropics (or coke) because they either want to sleep less and work…
  • 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 far harder than the other. Since sex won't be about becoming responsible for…
  • @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 am currently waving a neodymium magnet at my LCD.
  • @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 field is needed to change the card. Credit cards and such are high-co, they take…
  • 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 shoot you with bullets, like come from a gun. Iceland and other civilized…
  • 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 TASER, they're not likely to give up if it fails.
  • 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 might also not work. If it doesn't have to be cancer, injecting calcium…
  • 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 Mustang's wheels stay on the ground, so he doesn't have to lift the whole…
  • 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 thing is, it's probabilistic. If you want to assassinate someone and you…
  • @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 start. As for my two cents, those are both sports that favor high energy…
  • 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 (and trust) to the wiki here. Mass spec will tell you what is in a sample, to…
  • 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 nootropic stuff I've had an issue with was elevated histamine from Noopept.
  • 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 sucks for the person with the tattoo:…
