Happy Jeremy Bearimy Day!
Happy Jeremy Bearimy Month!!
Today is the every day you can never reblog this.
cnn reporters are so mealy-mouthed. "Both parties have accused each other of violating the terms [of the ceasefire]." Israel has been documented violating the agreement thousands of times. there are recorded names of the dead, public uncontested record of Israel's maintaining their blockade (and the inventory data in Gaza hospitals backing it up), and (again public) record of ordering the military to push forward and occupy 70% of the strip. none of these are "accusations" they are documented and observable facts in reality. and then they accuse Palestinians of violating the terms for refusing to lie down and die.
Arrest everyone involved.
Money saved: maybe a couple million dollars.
People killed: around three quarters of a million.
Baby Horseshoe Crabs: these eggs contain tiny horseshoe crab embryos, and the hatchlings typically emerge after 2-4 weeks, but it takes another 10 years for them to reach adulthood
These photos show the embryonic form of Limulus polyphemus, commonly known as the Atlantic horseshoe crab. The eggs of this species are initially opaque, with a grayish-blue, green, or pink coloration, but they become increasingly translucent as the embryos mature, providing a glimpse of the tiny horseshoe crabs developing within.
Above: several embryos twirling around in their eggs
The legs become visible roughly five days after fertilization, and the embryos begin to move shortly thereafter, eventually flexing their legs and twirling their bodies. They molt for the very first time just a few days later. Each embryo will shed its skin and grow a new one four times in total before it even hatches from the egg.
Above: Limulus polyphemus embryos
The hatchlings finally emerge after 2-4 weeks. The freshly-hatched larvae measure less than 1cm long, and they look just like miniature versions of their adult form, except that they do not yet have tails (which are actually known as telsons) and their exoskeletons are still soft and translucent. These young horseshoe crabs are often described as "trilobite larvae."

Atlantic horseshoe crabs generally spawn in May and June, with hundreds of thousands of individuals gathering along the coast on the night of the full moon and new moon. Each female lays up to 100,000 eggs per season, but very few of those offspring actually survive to adulthood. Most of the eggs are eaten or destroyed before they can even hatch, and many of the remaining larvae perish at some point during the 10 years that it takes for them to reach full maturity (i.e. the age at which they begin to reproduce).
Above: the freshly-hatched larvae
Wild horseshoe crabs can live to be more than 20 years old, and they can measure up to 60 centimeters (2 feet) long. They have 10 eyes in total, including two compound eyes that are specifically adapted for the purpose of finding a mate:
The most obvious eyes are the two lateral compound eyes. These are used for finding mates during the spawning season. Each compound eye has about 1,000 receptors or ommatidia. The cones and rods of the lateral eyes have a similar structure to those found in human eyes, but are around 100 times larger in size. At night, the lateral eyes are chemically stimulated to greatly increase the sensitivity of each receptor to light. This allows the horseshoe crab to identify other horseshoe crabs in the darkness.

Horseshoe crabs have been around for at least 445 million years, which means that these creatures are about 200 million years older than the dinosaurs and at least 50 million years older than trees, and yet their morphology has changed very little in that time. In fact, modern horseshoe crabs are frequently described as "living fossils," because they still look strikingly similar to their fossilized ancestors.

It's important to note that horseshoe crabs are not true crabs. In fact, they're not even crustaceans -- they belong to a completely different group of arthropods known as chelicerates, and they are more closely related to spiders and scorpions than they are to crabs.

Let's say I really wanted to reduce the number of children who die in car accidents. Car accidents are really bad, right? Nobody disagrees about that. And it would be much better for both the environment and the kids' health if they spent more time walking, or taking the bus. Perfectly reasonable. More cars off the road, safer roads, fewer kids getting hurt, healthier kids. A win-win!
Therefore, let's ban children from traveling by car and require all cars to have a scanner on the door that scans the government ID of everyone who gets in the car to make sure no kids are in there. After all, kids get hurt in car accidents all the time! We need to ban this right away!

âthe recording is of a blackbird in my garden in the north of scotland. the idea of the piece is that it's a letter home from a migrated bird, telling the family of its new life and making the connection between the migrant and the homeland.â - jennifer cantwell
Funny how that works
I am so pleased at how many notes are some version of âI donât fear the science, I fear the corporations who control itâ because that is EXACTLY the attitude you should have. GMOs can save us. Monsanto will kill us.
what people fear about GMO- âtheyre gonna make frankencarrots that crave human flesh and cause diarrhea â what GMO actually is- âwe made rice crop that is both drought resistant and flood resistant which will prevent about 20% of major famine disasters, also it now makes vitamin A because vitamin A deficiency in poverty stricken areas is a major killer of kids as most vitamin A rich foods dont grow thereâ what people SHOULD be upset about- âi made all crops sterile so all farmers have to buy the seed from me in perpetuity and i will sue anyone who tries to go back to crops that produce their own seedâ
Thatâs it exactly. GMO is great ciant corporations can go straight to hell
HEARTBREAKING: friends who i should be going to the movies and playing dnd and watching anime and cosplaying and going to the mall and having sleepovers and exploring the woods with live one hundred trillion miles away
I've noticed in recent years that, at least within mainstream usamerican culture, the sympathetic petty criminal archetype has largely fallen out of favor. you still have plenty of stories of noble nights, benevolent aristocrats, sympathetic mercenaries, but the idea of a thief with a heart of gold is increasingly rare. often petty criminals are just used as uncomplicated cannon fodder, so the protagonist has something human-shaped that they can kill or mutilate without remorse. you see this with dnd players often. the wicked king or the cruel dragon can be reasoned with, but a highway bandit robbing caravans to eat is perfectly fine to torture to death with sorcery
this is no less common outside of fantasy, either. god knows how many books, films, games, about sympathetic soldiers, police, even mercenaries. sometimes they try to reckon with the inherent violence and cruelty of these careers, but they rarely have the fangs for a message sharper than "sometimes good people have to do bad things." but a thief? a mugger? god forbid, a drug dealer? uncomplicatedly evil vermin, all. again, just used as cannon fodder, purely to provide something human-shaped to hate and brutalize without conscience
there is an obvious racial angle to this, as people grow more leery towards "those people are evil and inhuman because they look different," the message shifts to "those people are evil and inhuman because they are criminals," paired with heavily biased (and significantly more publicized) criminalization of racial minorities to achieve the same goal of publicly condoned repression and violence
Springing off of my addiction post once more, I am also skeptical at best of 12-step programs, because their framework has just never remotely aligned with my actual experience.
The substance I was addicted to was heroin. While I was actively addicted, it absolutely came before everything else. My life shrank around it. I kept using despite very real, very obvious negative consequences. If youâre looking for something that fits the âcompulsion + harm + loss of controlâ model, that was it.
But whatâs always sat strangely with me is what happened when that context changed.
Once my abusive relationship ended and I was no longer in an environment where it was readily available, it was shockingly easy to stop. Iâm not saying it was physically comfortable. My body was pretty pissed off for a while. But psychologically, it just didnât have the same hold anymore. I wasnât spending my days white-knuckling cravings or constantly thinking about it. It dropped out of my life in a way that, according to the 12-step model, is not really supposed to happen.
And thatâs where my issue with that framework starts.
Because 12-step ideology tends to assume that if you have ever had that kind of relationship with one substance, it reveals something fundamental and permanent about you. That you now have a generalized âaddictive natureâ that will attach itself to other substances or behaviors if youâre not constantly managing it. That you are, in some essential way, always on the verge of transferring that pattern onto something else.
And that just hasnât been true for me.
I was a near-daily cannabis user for years. When it started consistently making me feel physically uncomfortable instead of good, I stopped. No drawn-out battle, no existential crisis, just âthis isnât giving me what I liked about it anymoreâ and I moved on.
I drink occasionally, in social or celebratory contexts, and I genuinely find alcohol kind of boring outside of that. It doesnât have much pull for me.
I tried gambling once, got annoyed at how tedious and overstimulating it felt, and left the casino in under an hour. I have not felt remotely compelled to revisit that experience.
I use the internet a lot, and I play a handful of video games, but I can also go on a camping trip with no signal and be completely fine, unless you want to try and find something pathological about nature photography, in which case you can blow it out your ass. If anything, I generally enjoy the change of pace. Thereâs no sense of panic or withdrawal or âI need to get back to my computer/consoles immediately.â
So when I hear the idea that addiction is this broad, transferable trait that will latch onto anything with quick reward or low friction, I just donât see it reflected in my own life.
What does make sense, looking back, is context.
When I was using heroin, I was in an abusive relationship. My environment was unstable, stressful, and honestly pretty bleak. The substance didnât just exist in a vacuum. It fit into a specific set of conditions where it functioned as relief, escape, and regulation.
When those conditions changed, the behavior changed with them.
That doesnât mean there was no dependency. There obviously was. It doesnât mean there were no consequences. There very much were. My grades suffered. I dropped out of college. I lost my apartment because staying out of withdrawal and numbing out from the abuse felt more important than paying rent.
But it does suggest that what we call âaddictionâ might not always be this permanent, identity-level trait that needs to be managed forever. Sometimes it looks a lot more like a relationship between a person, a substance, and a specific environment.
When thatâs the case, then a framework that assumes universality - âif this happened once, it will always be waiting to happen again, with anythingâ - is going to miss a lot of variation.
Iâm not saying 12-step programs canât help people. Clearly they can, or they likely wouldnât exist in the way they do. But I do think theyâre often treated as the model of addiction rather than a model that fits some people and not others, and when your experience doesnât match that model, many people who swear by them will assume that you are misunderstanding yourself, in denial, or ânot taking it seriously enough.â This paternalistic attitude only serves to make me even more skeptical of the framework.
For me, what mattered wasnât declaring myself permanently âaddictiveâ or treating every pleasurable behavior as a potential threat.
What mattered was getting out of the environment where that pattern made sense in the first place.
Rat Park, people. Stop forgetting about Rat Park.
âaddictionâ might not always be this permanent, identity-level trait... Sometimes it looks a lot more like a relationship between a person, a substance, and a specific environment.
I have helped change more individual behavior by changing the environment around them than I have by working on their behavior.
