  Technically, this is processed cake. Yellow cake that is.

  As a Canadian, I share your confusion. I think that phrase was just a common descriptor of mitochondria in US textbooks, or a catchy line in a popular US biology video.

  It’s just strange enough to make a big impression on bored students, so I’m not surprised it’s been memed so hard.

  This isn’t learned behaviour though. The kites tried eating the invasive snails immediately, but they were too large to be cracked by their beaks, being two to five times larger.

  The change to eating the larger non-native snails was facilitated by larger beaks seen in the years after the invasion.

  It seems like the local applesnail had a crash due to drought in the early 2000’s (partly caused by the draining of wetlands for development), and the invasive island applesnail was first seen in 2004. There are even more species of invasive snail now, but the opportunity likely arose because of a population crash.

  The fittest in this case are the kits that can eat the snails they find, not by being less picky, but by having larger beaks.

  Evolution is just the change in allele frequency of a population over generations. This includes 90% of the population dying before they figure out new food.

  Cats were originally used for their curiosity, but training hamsters and eventually parakeets led to much smaller machines.

• ⁨Comment⁩ on ⁨[deleted]⁩ ⁨⁨4⁩ ⁨weeks⁩ ago⁩:

  By that argument, most of these should be black.

• ⁨Comment⁩ on ⁨[deleted]⁩ ⁨⁨4⁩ ⁨weeks⁩ ago⁩:

  Selecting one wavelength are discarding all the others, and sometimes shifting that wavelength to a more convenient hue is great for science, but feels like cheating when looking for a specific colour.

  It’s like looking for pictures of red cars, and getting a car that’s 90% rust, a picture taken in a forest fire, and a picture taken through red-tinted glass.

• ⁨Comment⁩ on ⁨Devices (fanmade, obviously)⁩ ⁨⁨4⁩ ⁨weeks⁩ ago⁩:

  Hey! I’m using one of those devices!

• ⁨Comment⁩ on ⁨(゜O゜;⁩ ⁨⁨4⁩ ⁨weeks⁩ ago⁩:

  Or just that it needs to focus on from of itself like filter crabs, or that it needs to see through things like kelp forests or hole enterances.

  Given it’s size and the extreme binocular vision, it’s unlikely to have any ambush predators.

  I looked it up, it has bony plates all over it’s body and likely a lateral line, so seeing predators directly may have been less necessary. It was also a suction feeder, so likely an active predator of much smaller things. It may have needed good forward vision because it’s maneuverability was poor.

• ⁨Comment⁩ on ⁨science never ends⁩ ⁨⁨5⁩ ⁨weeks⁩ ago⁩:

  I’d argue that we can’t do a resurrection because that’s really complex, not because we don’t know how.

  I’ll also point out that there are people alive today who were declared medically dead that live normal lives because we made their heart beat again.

• ⁨Comment⁩ on ⁨Chocobo⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

  TL;DR: Beaks are a lot lighter and more easily adapted than teeth.

• ⁨Comment⁩ on ⁨Bees don't have lungs.⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

  They aren’t insects, but most arachnids have book lungs, which are basically a pocket full of air gills.

  I think it’s been styled to match the spectrographs in the background.

  Still hard to read.

• ⁨Comment⁩ on ⁨Give us your craziest ocean facts. 🦑⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

  It might be more accurate to say the average person knows more about what we don’t know about the ocean than what we don’t know about the moon.

  We have a decent idea about what can and may exist in and about Earth’s oceans, but less about the moon; and most people assume it’s just a dusty rock too.

• ⁨Comment⁩ on ⁨p r e s s u r e⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

  And only 20% as wrong! I hope. :P

• ⁨Comment⁩ on ⁨p r e s s u r e⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

  That would be a stupidly hight amount of charge.

  For a very rough estimate, thunderstorms peak at about 6.7 nanocoulombs of charge per m³, or 4.2e10 fewer electrons per m³. Cumulonimbus clouds have roughly 2 grams of water per m³, or 6.7e22 atoms per m³. Thus, thunderstorms have 1 in 10e12 fewer electrons.

  To fully ionize water, you would need something like a trillion times as much voltage as lightning, and the ability to insulate the sample from other sources of electrons like any nearby matter.

  This might be feasible at very small scales, but the result would be just as dangerous. A bunch of protons that really want electrons nearby would pull lightning from anywhere they could, and would be unbelievably corrosive. Something like a pH of -23.7, although pH breaks down long before this point.

  Such a substance completely devoid of electrons would also repel itself very strongly, so it would evaporate into gaseous protons basically instantly. “Normal” plasma is much more stable because the electrons are separated by temperature rather than by electric change. High electric charges are much more difficult to contain.

  I’m not a physicist though, so I’m likely wrong on the details.

  Also remember that carbon is lost as the metal is worked, so the strength can be increased simply by working the metal longer. This is how wrought iron is produced, although wrought iron ends up having a much lower carbon content in the process of removing slag.

• ⁨Comment⁩ on ⁨p r e s s u r e⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

  That’s a really salty fluid, or a strong acid/base. Plasma just has temperature driving the ionization, rather than chemistry.

• ⁨Comment⁩ on ⁨p r e s s u r e⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

  Gender BEC would be a low energy gathering where all of a sudden everyone is on the same wavelength.

  Gender Time Crystal would be someone who switches between two genders regularly.

• ⁨Comment⁩ on ⁨shrimp colour drama⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

  By the same logic, we don’t detect light, just the change in shape of certain proteins. The sky isn’t blue, it’s a subset of sunlight. We don’t really touch things, we transmit forces with tiny magnets. Computers don’t really do math, they just arrange states in certain ways.

• ⁨Comment⁩ on ⁨[deleted]⁩ ⁨⁨3⁩ ⁨months⁩ ago⁩:

  I somewhat agree. Given enough time we can make a machine that does anything a human can do, but some things will take longer than others.

  It really depends on what you call human intelligence. Lots of animals have various behaviors that might be called intelligent, like insane target tracking, adaptive pattern recognition, kinematic pathing, and value judgments. These are all things that AI aren’t close to doing yet, but that could change quickly.

  There are perhaps other things that we take for granted than might end up being quite difficult and necessary, like having two working brains at once, coherent recursive thoughts, massively parallel processing, or something else we don’t even know about yet.

  I’d give it a 50-50 chance for singularity this century, if development isn’t stopped for some reason.

• ⁨Comment⁩ on ⁨Let me be *perfectly* clear...⁩ ⁨⁨3⁩ ⁨months⁩ ago⁩:

  No, fish have digestive tracts that go all the way through. Changing that would be way harder than keeping it mostly empty or full of water to make it clear.

• ⁨Comment⁩ on ⁨Dunning-Kruger⁩ ⁨⁨3⁩ ⁨months⁩ ago⁩:

  Some XX people live their entire lives as men without ever knowing otherwise, and the same happens with XY individuals living as women. Even having children won’t reveal the apparent discrepancy, unless they need certain tests done.

  This is fluorescence, which turns invisible light into blue light. Like how your teeth and some clothes glow at a rave or glow bowling alley.

• ⁨Comment⁩ on ⁨Entropy? Never heard of it.⁩ ⁨⁨4⁩ ⁨months⁩ ago⁩:

  There’s no profit motive for large scale carbon capture anyway, so big CC plants and big nuclear plants would need the same political will.

  Wow, I don’t think a single one of those people even know what a soldering iron is.

• ⁨Comment⁩ on ⁨imagine⁩ ⁨⁨4⁩ ⁨months⁩ ago⁩:

  Sure, I don’t disagree. The difference is I had a source to criticize. You know what info I was working with and can guage how reasonable my claim is. If you go around to people convinced of something and say “Nuh uh”, it doesn’t matter if you’re correct, you’ll be laughed out of the room.

• ⁨Comment⁩ on ⁨Gottem. :)⁩ ⁨⁨4⁩ ⁨months⁩ ago⁩:

  The oceans would eventually freeze over, but the deep ocean could stay liquid for tens of millions of years. Ice is a pretty good insulator, and there is more than one moon in the solar system suspected to have liquid oceans under a layer of ice.

  Evolutionary pressures form new organisms, which feed biodiversity. More crabs aren’t as diverse as that sounds.
