Like all living things, humans are bio­luminescent (meaning we glow) – We glow brightest during the afternoon. weirdinteresting & funny facts


i’ve been staring at this for like 5 minutes. so.. what. i don’t think people glow. but this is telling me that we actually emit visible light.. especially in the afternoon?? am i reading this right or what

"all living things" plants. when do the plants glow

science side of tumblr pls

I’m not from the science side of tumblr, but here’s the answer anyways:

 Basically, all living things are bioluminescent because every living thing has chemical reactions occurring in their cells. The energy created from these chemical reactions physically manifests as light, thus… all living things naturally glow.

 However, this glow cannot be seen by the human eye. In fact, the only way they’ve ever captured this light is through special cameras. Using these ultra special cameras, they’ve imaged subjects’ bodies over 24 hour periods. It has been found out that humans emit the most of this glow during the afternoon (about 4 PM), it is the weakest in the morning (about 10 AM), and the brightest light is emitted from the cheeks, neck, and forehead.

The light is about a thousand times weaker than what humans can perceive.

 Basically, it’s a side effect of metabolic reactions. It’s been suspected that humans are bioluminescent for years, but they weren’t able to confirm it until recently thanks to technology and a man named Masaki Kobayashi from the Tohoku Institute of Technology.

Magical Paths Begging To Be Walked

Roads and paths pervade our literature, poetry, artwork, linguistic expressions and music. Even photographers can’t keep their eyes (and lenses) off of a beautiful road or path, which is why we collected this list of 28 amazing photos of paths.

Paths like these have a powerful grip on the human imagination – they can bring adventure, promise and change or solitude, peace and calm. There’s nothing like a walk down a beautiful path to clear your head – or to fill it with ideas!

I’ll leave you with an excellent quote from J. R. R. Tolkien’s works while you enjoy these images; “It’s a dangerous business, Frodo, going out your door. You step onto the road, and if you don’t keep your feet, there’s no knowing where you might be swept off to.

I can’t tell what my favorite part is, but it’s either

  • scientists wasting budget and time to see if ants count their steps
  • the idea to put ants on stilts
  • there had to be a guy who made ant stilts and put them on the ants
  • confused ants

OMG this isn’t even the beginning of what scientists have done to ants. Gather round bbs while I tell you some stories.

There was one entomologist down the hall when I was in undergrad who wanted to figure out what goes down in the habitat when new species of ants appear. 

So naturally the solution was to take a bunch of colonies (conveniently housed in tupperware containers), give them names like Moria and Mordor, and set them all up in an “arena” with food. There were notebooks full of lines like “2:36pm Two Mordor ants attack Moria ant” “2:37 pm Moria ants send reinforcements; first ant sent alarm call?” scattered all over the table because they managed to convince undergrads that sitting around taking handwritten notes on what ants are doing today was good science experience (partially because it’s true).

Now in the entomology dept at my current uni there’s an entomologist who studies ants and one who studies termites and they’re married to each other and they’re adorable. Also back in grad school they liked to take extra leftover colonies of their research bugs and make them fight. The ants always won. 

But the BEST is this guy at our local USDA research station who’s working on parasitoids for fire ants. 

So you know how there are wasps that lay their eggs in caterpillars and eat them from the inside? bitches that is only the BEGINNING of what Mother Nature has in store for insects. 

There are flies that lay their eggs on fire ants. The larvae hatches out and burrows into the fire ant’s head and eats the insides and straight-up turns the ant into a behavior-controlled zombie. Right before it’s ready to pupate, it pops the ant’s head clean off. And then when it’s done pupating it crawls out between the ant’s jaws. It’s AWESOME.

Now the thing is before you can release these parasitoid flies into the wild, you have to raise a bunch of them in the lab. That turns out to be really tricky because fire ants FREAK OUT when they hear the flies coming. They all run and hide in their nest like a bunch of losers. That means the scientists have to find some way to get the fire ants out of their nests so the mama flies can get some victims to lay eggs on.

The scientists came up with the perfect solution. They figured out that the only thing that can motivate fire ants to run around when there are phorid flies around is the need to SAVE THE BABIES! 

So what they do is take both adult ants and a nice big scoop of brood (the part of the nest that has all the baby ants in it) and stick them all in this tray. Over this tray there’s some homemade mechanical gearing that controls two shelters. They switch between being down flat on the surface where ants can hide under them, and being picked up and exposing all the ants underneath. Every five minutes it alternates which one is up or down. Whenever it switches the fire ants zoom around frantically trying to run the babies to the other shelter that’s now down, and while they’re doing that MUHAHAHAHAAAA IT’S EGG-LAYING TIME for the flies. 

And when I say “shelters” I mean “Solo cups” because this is college, folks.

Anyway, watching this thing at work is 75% soul-deep satisfying because if you’ve lived with fire ants in their ecologically-uncontrolled plague state you know what I’m talking about; and 25% utterly horrifying. Also it makes me glad to not live in medieval times because there was no such thing as entomology back then and people with that kind of imagination would have had to find other ways to use it.
