    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.




  • 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.

    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.
