Propylene glycol is also known as fog juice, the stuff that goes into stage smoke machines, and it's used as a food additive. It metabolises to lactic acid and is considered safe, which is why it's used in e-cigs.

Antifreeze is usually ethylene glycol, which is toxic. However, both salt and ethanol can also be used as antifreeze, and while they can be lethal in sufficient quantities they too are considered fit for human consumption. Calling something "antifreeze" tells you no more about its toxicity than calling something "natural" (i.e. snake venom) or "organic" (i.e. benzene).

Colour would be an improvement, but not as much as you might think. CMYK is no problem, but the RGB hues are limited by the quality of the inks/toner, paper, the mixing pattern and print resolution versus dot have a safe error margin you wouldn't want to use intermediate hues, so realistically that's three bits per dot. Since a scanner can't tell a halftone from a faded print it may not be a good idea to vary the print density, though this could be mitigated with reference colour bars, in which case each dot would be three bits plus a remainder which could be paired with an adjacent dot(s) to squeeze out some extra bit depth. On the down side, each dot would have to be large enough compared to the scanner's optical resolution to prevent colour errors due to aliasing.

(NB: deliriously tired, probably miscalculated the possible bit depth, but you get the idea)

Fuel vapour inside a tank rarely has the correct oxygen mix to ignite. Rupture the tank and spray the fuel all over the place and suddenly it does. Aircraft fuel tanks (not to mention the rest of the plane) tend to rupture quite significantly on impact, while gas station tanks are usually underground and seldom fall out of the sky at a few hundred knots.


Clinton Campaign Chair: 'The American People Can Handle The Truth' On UFOs ( 287

An anonymous reader writes: In what seems like an April Fools' Day prank story but is surprisingly real, Hillary Clinton's campaign chair, John Podesta, says that he has convinced Hillary Clinton to declassify as many documents as possible related to Area 51 and UFOs. On the matter of alien visitation, Clinton has previously stated that "I think we may have been [visited already]. We don't know for sure." Meanwhile, Democratic rival Bernie Sanders has been dismissive of UFO talk. And on the other side of the isle, everyone surely already knows how likely Republican nominee Donald Trump feels about illegal aliens. "The U.S. government could do a much better job in answering the quite legitimate questions that people have about what's going on with unidentified aerial phenomena," said John Podesta, who was also a chief of staff to President Bill Clinton.

People Feel Weird About Touching Robot Butts, Researchers Find ( 162

An anonymous reader quotes a report from TechCrunch: How would you feel if a robot asked you to touch its butt? Maybe it sounds like a silly question, but as robots proliferate and anthropomorphize, it's actually something that needs to be considered. So scientists at Stanford considered it. The study, to be presented soon but previewed by IEEE Spectrum, is entitled "Touching a Mechanical Body: Tactile Contact With Intimate Parts of a Human-Shaped Robot is Physiologically Arousing" -- and really, the title says it all. The researchers sat volunteers at a table with a Nao humanoid robot reclining casually on it. They were told (by the robot, in fact) that it was a vocabulary exercise focusing on terms for body parts. Volunteers were told by the bot to, for instance, "touch my ear" using their dominant hand, while the non-dominant hand remained on a skin conductance sensor that loosely monitored their physical state. When asked to touch "high accessibility" areas -- places we normally touch on other people, like shoulders and elbows -- volunteers did so without hesitation or agitation. But "low accessibility" areas -- this would be the robot's butt and where its junk would be -- produced delay and that arousal we talked about.

The harebrained conspiracy nuts don't consider themselves idiots...quite the contrary, they consider their belief in conspiracies to be evidence that they're more clever than the scheming masterminds (not to mention the rest of humanity, hence the word "sheeple").

Dunning-Krugery at its finest.
