    As humans, our eyes contain 3 different types of cones (red, blue, and green). With these we can see around 1 million different colors.

    But Mantis Shrimp have 16 different types of cones in their eyes! And with those 16 cones they can see a whopping… 16 colors.

    While our brains allow us to mix and match the different bands of light our eyes detect in order to “see” a wide variety of colors, Mantis Shrimp lack that ability. What they detect is what they get, there’s no neural post processing, or at least not any that allow the perception of mixed colors.





  • “Safety Protocols Off”

    What the fuck? Why is that an option through a vocal command?! If it’s really needed, that should require someone from engineering to make the adjustment and it better be for a damn good reason, not just “I wanna experience real danger”. With the amount of issues that come from Holodeck malfunctions, it’s insane that Star Fleet allows them at all, especially because they seem to fail quite often in their hands.

    Seriously, Quark has a better safety record than Star Fleet when it comes to those. His holodecks have only had ONE major incident (Our Man Bashir) and even then it could be argued that the holodeck saved the crew by injecting their patterns into the program when they would have otherwise been entirely lost. Compare that to the Enterprise or Voyager where they have a Holodeck disaster every other week, often self-inflicted.



  • How are the dangers of illegally entering a country in any way the problem of said country? Like, if someone was trying to break into your house through a back window and wound up stepping into a nest of ground hornets, no one would say it’s your responsibility to make sure the non-path to your back window is free of hazards. Does it really need to be stated that countries are under no obligation to ensure illegal routes across their borders are safe?

    If they go the route of TX and actively make the area more dangerous, that’s an entirely different story. But it’s the US/Canada border. In winter. It gets cold. If your strategy for entering a country involves standing outside in Sub-Zero temperatures with inadequate clothing… You need a different strategy.



  • That’s the thing about the “fuck cars, everyone should switch to bicycles” mindset. For most cities, especially in the US, it’s just not safe yet.

    You can say that if more people rode, or bike friendly infrastructure was put in place, then it’d be safer, but it’s just not safe yet.

    You can say it’s more healthy than cars and doesn’t take as much time or energy as people think, especially with e-bikes; but it’s just not safe yet.

    After seeing my 3rd friend in Seattle (supposedly a fairly “bike friendly” city) get hit by a car and need to be hospitalized, I decided biking is not for me and may never be. Since then, 2 more friends have gotten in accidents. I don’t exactly have a large group of friends and if you widdle that down to friends who predominantly bike as their method of transportation, I’m looking at over a 60% accident rate for bikers I know.

    It’s just not safe yet.

    Oh yea! I forgot about that one! It’s starting to be used a lot in implantable medical devices to generate a small current. There was also that thing a few years back that was trying to use it to generate power from waves/tides; not sure if that actually got past the proof-of-concept stage though.
