The phrase āmost autistic girl in all the landā popped unbidden into my head last night and I couldnāt remember who had made the joke and had to Google it
You know how theyāre colonial organisms? My whole life I thought that meant ātheyāre made out of thousands of almost microscopic little guysā. You know, like every other colonial organism.
Turns out thatās not true.
Theyāre made of four guys.
One guyās the tentacles, one guyās the stomach, one guyās the gonads, and one guyās the funny balloon sail.
You are angry about something. āClam down,ā I text you. You assume I have made a typo, but in fact I am holding a small soldier clam in my hands. He died so young. War is hell
Hello hellsitegenetics. I have discovered that I did absolute shit on my Genetics unit so far. If you were to BLAST this ask I will start praying to the creature that appears for them to aid me in the final exam so that I can have a GPA that is closer to what I wanted

hey. listen. when you use too much detergent in your laundry you aren't making your clothes cleaner, you are making them degrade faster. the machine isn't able to rinse out the entire cup of soap you put in, so some of it is left in the fibers of your clothes. when they dry this makes the fabric stiffer and more brittle, so the fibers are more likely to erode and break. over time this makes your clothes wear out much faster than if they were properly rinsed with minimal soap. you are wasting money by overusing detergent, not just on the detergent itself but the clothes you are shortening the lifespan of.
you are also ruining your clothes by cramming too many into the wash at once. the machine washes them by agitating them and rubbing them together but if they're crammed in there there's more friction. so they're less likely to get clean and they're wearing each other out. don't use tiny loads of laundry bc that's a waste of water but focus on medium sized loads with only a tablespoon or two max of laundry detergent.
you can also hang up your cotton shirts to dry to prevent them from shrinking in the dryer, and to maximize the lifespan of printed graphics on your shirts or sweatshirts. this saves electricity and keeps your clothes nicer for longer.
fabric softener is a scam, you don't need it because most detergents come with a softening agent already. dryer sheets are handy to minimize static in the dryer, but you can get a reusable wool ball that does the same purpose so they're not necessary either.
use bleach detergents sparingly, only if you notice your whites becoming stained or dingy. using bleach on every load of whites will degrade them.
also most of the time you really only need to wash with cool water. unless something is really soiled, (especially with something greasy, remember heat melts and removes grease,) cold water works just fine for day to day dirty clothes.
Weāre gonna talk about hagfish today, since it is Their Day
Hagfish are vertebrates, but they have no vertebrae! They lack bones entirely, with just a cartilaginous skull and a notochord (making them the only animal with a skull and no spine). They also have no eyes and no jaw. They also like to cuddle.
Exactly where they fall on the tree of life has been an interesting topic. Historically, they were placed as the sister-group to vertebrates; the vertebrate that diverged the earliest, and remained very primitive-looking. However, with new fossil evidence and DNA analysis, weāve figured out that they are closest related to the lamprey, another jawless fish that does have eyes and bones! Which means the ancestors of the hagfish did as well, but somewhere along the line they decided, āscrew it, Iām going back to being a Wormā.
The hagfish spends most of its time at the bottom of the ocean, sniffing around for prey. Although they do actively hunt and catch their own food, itās much easier to eat things that are already dead, so theyāre frequently seen snootling around whalefalls and bait set out by scientists, where they feed by rapidly spinning around until theyāve bored a hole straight through the skin and can get to the tasty insides!
But wait, how does a jawless animal feed at all? It just has a little :O face with no teeth!
Well, great news! That cute little :O isnāt itās mouth! Thatās itās nose! Itās mouth is underneath.
Aināt that nifty?
Being a squishy little guy with no teeth or eyes, defending itself is kind of difficult. Luckily, no one wants to eat a hagfish, because they are gross af. They secrete a very thick slime that chokes predators. About 4% of a hagfishās body mass is pure slime. This slime is also apparently useful to humans, because it contains strands that are stronger than nylon, offering a way to make more durable and environmentally friendly fabric!

Oh look, it seems like there's a Republican-led movement to purge voter rolls in the lead-up to the election! It's almost as if your vote matters and they don't want you to vote! Anyway, I whipped up a quick map (based on this) that shows when the voter registration deadline is in each state. There are a few deadlines coming up in the next week or so.
If you live in a state that regularly purges voter rolls for infrequent voters (the orange ones in the first map), or if you moved recently, it's good to check if you're still registered to vote.
Vote.org makes it super easy to check your registration: https://www.vote.org/am-i-registered-to-vote/
Just put in your address and DOB and they'll tell you whether you're registered. (And they give you a quick link to register online if it turns out that you're not! Only the 9 states in white on my map don't have online registration, and for those they provide instructions on how to do it via mail or in person.)
So yeah, give yourself peace of mind -- do a quick check. :)
Quick correction - Minnesota has same day voter registration, so if you aren't registered you can bring proof of residence with you and register when you vote, all the way up to election day, November 5.
