Annual Viral Expression in a Sea Slug Population: Life Cycle Control and Symbiotic Chloroplast Maintenance.

Maybe some of you have heard about that awesome sea slug that contains algae chloroplasts and can actually photosynthesize like a plant, right?

Well, it also seems that its ability to utilize chloroplasts was a mutation induced by a virus.

The virus continues to operate in the maintenance of this process.

100% of the species is infected.

……And after they lay their eggs, 100% of them are killed by that virus. Not by “aging” or some other natural life cycle trigger. They just stop being necessary now that they’ve made a new generation and the virus re-activates what were probably its original deadly symptoms when the two first met millions of years ago.

hi what the FUCK

I’ve only read the abstract but

a) this makes it the second animal clade I know of to have a symbiotic relationship with a virus, Ichneumons and their ilk being the first

b) Synchronized mass die-offs, what the hell, why isn’t that selected against AF

@purgatory–and–probiotics help

It’s not selected against because the virus-induced mutation provides such a big advantage that the infected slugs produced more successful offspring in greater numbers than the uninfected ones. Now there aren’t any uninfected ones to select against the infected ones. I’d suspect the virus kills the adults in order to ensure the new generation has enough food, but I don’t have anything to confirm that.

Hi, anon.

I’m not sure if you know this, but it’s rude to send someone RP starters without them having asked. Especially lewd ones and ones completely unrelated to things they’ve posted about recently.

If you want to RP, I’d suggest looking on an actual RP site, or coming off anon and actually asking people.

Here’s a “life-hack” for you.

Apparently concentrated Kool-Aid can be used as a pretty effective leather dye.

I was making a drink while cutting the snaps off some new straps for my pauldrons and I got curious, so I tried it, thinking, “ok even if this works, it will just wash out.”

Nope.

It took the “dye” (undiluted) in about 3 seconds. After drying for about an hour and a half, it would not wash off in the hottest tap-water. It would not wash out after soaking for 30 minutes.
It did not wash out until I BOILED it, and even then, only by a tiny bit and it gave it a weathered look that was kind of cool.
Add some waterproofing and I’d wager it would survive even that.

That rich red is only one application too.
Plus it smells great, lol.

So there you go, cheap, fruity smelling leather dye in all the colors Kool-Aid has to offer.

WELL THEN!

this may be important to some of my followers *and certainly not just getting reblogged because of my costuming and my boyfriends desire for leather armor*

When I was in middle school we used to use it to dye our hair.  Potent stuff.

If you’re dying anything with kool-aid it’s best to use SUGAR-FREE ones otherwise the thing you’re dying might get all sticky

the flavor only packets where you are supposed add sugar are the best. 
they will dye any natural fiber: leather, wool, cotton, hair,  flax, jute, silk and so forth. 
heat the dye water so it is more potent. 
let dry then rinse excess out in cold water. 
there’s  a whole system to this. 

Oh my god

This will prove very useful for any future cosplays I wanna do.

DUDE

Oh yeah

koolaid powder is basically dye (acid dye, specifically) and a buttload of citric acid. so yup it will dye any protein fiber MOST handily. you may find it less effective on plant fibers.

i did my own koolaid yarn a few years ago!
