ive been reading a book that basically explains how so-called “brain differences” between the genders is the result of gendered socialization and not the cause of it. i honestly expected the book to be very cis-centric but its actually the opposite, the author stresses that testimony from trans ppl is actually indispensable because we’ve, in a sense, “lived both experiences”

more cis feminists should have this mindset

one of the first examples that she uses to introduce her point about how perception by others can shape a person’s performance actually uses a trans woman. it explains that as a certain trans woman became to be seen as a woman more and more frequently, the ppl arond her eventually started viewing her as being ill equipped for tasks that they did not bother her about pre-transition. eventually she even found herself underperforming in these tasks herself.

whats the name of the book

Delusions of Gender by Cordelia Fine

Here’s a pdf, babes ❤

I knew it was this book before I’d finished reading the first two lines. Honestly this book is indispensible if you want to debunk any gender determinism people claim is science. I can’t recommend it enough.

She’s written a new one! It won the Royal Society prize for science book of the year, and it’s called Testosterone Rex, and it is excellent.

(Bonus: it’s making old white men really really mad.)

(Bonus bonus: I am myself a neuroscientist, and the old white men mentioned above – who are not – could not have missed the point harder if they’d actively tried. Which. Maybe?)

In 2010, the RIKEN institute in Japan created mutant cherry blossom trees by firing ion beams at them in a particle accelerator. The mutated trees now bloom four times a year and produce more flowers.

a wise use of science powers

ok so i’m not saying this is the most japanese thing ever, but I’m not saying it’s not

“we have a ray gun that creates mutants” anime level 8/10

“we used it to make super cherry blossoms” japan level 10/10

“so are they like firebreathing carnivorous flowers or” “no they just make more flowers, more often” aesthetic level 11/10

“well done, this is exactly what we hoped would happen when we paid a zillion dollars to build a particle accelerator” —the project backers

Particle physics is fucking magic
Some wizards took a magic box into the woods and fucked up some trees. I love this shit

“ok so should we mutate like a super army or-” “no. this sakura tree.” “but why” “hanami four times a year instead of once. imagine”

I read your post and I’d like to help you get started. Please talk to me about how vegetables aren’t real, because that sounds like an interesting af conversation.

thecrackedamethyst:

Well let me tell you.

Everybody and their cousin has experienced the argument “is a tomato a fruit or a vegetable” at some point in their lives. It’s a fun bit of trivia, and let’s know-it-all’s speak condescendingly, or at least they did like 10 years ago. “Knowledge is knowing tomato is a fruit, wisdom is not putting it in a fruit salad”. Whatever.

Which brings up the point, that botany and culinary sciences are very different. Botany is the study of plants, culinary is cooking and how things taste. Botany is science, and it has rules (kind of), where cuisine is full of guidelines that are completely cultural.

Tomatoes are a fruit. A fruit is how many plants have babies, and are made in the ovary of a flower. I have a diagram.

Armed with this knowledge we can know that tomatoes, cucumbers, squash, beans, peas and peppers are all fruit.

“Now”, I ask you, “what are lettuce, and cabbage, and spinach, and kale”?

“Vegetables”, you say, assuredly.

“Yes, but, what are they?”

“…vegetables”, you say, slower, and louder this time, not quite sure what I’m wanting from you.

No. They are leaves.

What are carrots, beets and radishes? Roots. What about celery and rhubarb? Stems. Potatoes? Tubers (food storage for the plant, and where new plant babies will grow from). Garlic and onions? Bulbs (also food storage). Mushrooms? They’re not even a plant, they’re a fungus, in the kingdom of fungi, which is somewhere between the plant and animal kingdoms.

“Vegetables” is just a word for plants that we eat, that doesn’t have enough sugar to be a fruit, and not enough flavour to be a herb or spice.

Botanically speaking, there is no such thing as a vegetable. They’re just different parts of a plant that happen to be edible.

There are other plants, normally considered weeds, that can be “eaten like a vegetable”. Dandelion, stinging nettle, dock, purslane, can all be cooked and eaten, making them vegetables, at least to the people to treat them as such. It’s all very cultural, and biased, and based on nothing but what people think it is. Therefore, they are not a real thing, it’s just a concept.

fanfic: this character has had several bottles of hard liquor and they’re just slurring their speech slightly and for some reason are not in the hospital with alcohol poisoning

me: ….you’ve literally never had a drink in your life have you

very good point.

Alcohol For the Non-Drinking Fanfic Writer, a primer by me

There’s a shit ton of variability in response to alcohol depending on body mass, history of drinking (your liver can upregulate the CYP450 enzyme responsible for metabolizing alcohol but only to a certain point; chronic alcoholics hit a point where their livers are so trashed they lose this and go back to getting drunk off small amounts of alcohol), and ethnicity (people of East Asian descent are more likely to lack a critical enzyme for breaking down one of the metabolic steps in the degradation of ethanol and are stuck in the shittiest part of it, with flushing and nausea), and other factors.

But if I had to guesstimate for writing:

1 drink (a tall glass of beer, a can of beer, or a shot of hard alcohol in a cocktail or alone): are you a burly dude? you may or may not feel it. are you a tiny lady? you will probably notice it.

2 drinks: burly dude may or may not be noticing it. tiny lady like me: this is a sweet spot where you’re talkative but not drunk. (Note: people don’t go from zero to “so drunk you remember nothing/are profoundly disinhibited.” There’s a lot of ground to cover in between.)

3 drinks: burly dude probably feeling it, tiny lady getting drunk.

4 drinks: burly dude still feeling it, tiny lady ready to FUCKING FIGHT YOU

5 drinks: burly dude, slow down, buddy, you gonna polish off that six-pack by yourself? That’s going to hurt in the morning. Tiny lady: oh my GOD stop. Go to bed.

This is where we draw the cut-off for a “binge,” if you were wondering. More than this and you’re officially binge-drinking, where your odds of serious harm go up sharply. From alcohol, but also from the bad decision dinosaur that plagues you when you binge-drink.

a fifth of anything by yourself: Sir. Sir, can you hear me? Sir, I need you to open your eyes. Squeeze my fingers. Sir, you’re in the emergency room.

Splitting a bottle of wine between two adults: generally like three drinks each, you’ll feel it but you’ll survive. (A bottle of wine between three adults: usually not quiiiiiite enough.)

An entire bottle of wine by yourself: oh, so you enjoy suffering?

Other Fun Medical Alcohol Facts: high-proof alcohol like vodka will temporarily paralyze your pyloric sphincter, so the alcohol can’t get into your gut for about twenty minutes. Then, when it DOES get into your small intestine, enjoy getting uncomfortably drunk too fast.

Alcohol is a zero-order metabolizer: that means that nothing on Earth can sober you up except time*, and the time it takes is linear, directly related to how much you drank. Most of us can clear about a drink an hour, so if you’re drinking slowly you can stay roughly sober all day. Most of us don’t drink that slowly. Hangovers are made awful by a metabolic intermediate (literal acid in your blood!!!! it’s so shitty!!!!!!!) that makes you nauseated and feel super gross, and not every drinking episode will lead to a hangover, and severity of hangover varies greatly by person and amount drunk.

So please never write someone having coffee to “sober up.“ Now they’re drunk AND they can’t sleep. Bad combo. Sucks for driving. Splashing cold water on your face? No. Amphetamines? Good Lord what’s wrong with you. Look, the room’s gonna spin, you fucked up your endolymph in your semicircular canals, deal with it. You can partially override that with proprioceptive feedback–keeping one foot on the floor to get tactile input–but it’s just gonna suck for a while.

The variability in capacity is real; my aunt-in-law, who is roughly my size, can drink me under the table easily. She’s a high-powered business executive who has martinis with lunch. I tried to keep up with her once and had to call in sick. So you don’t HAVE to write a character having a “normal” alcohol tolerance, but don’t get into “yep, definitely alcohol poisoning” territory, please.

*this is technically not true, but no substance you can get your hands on will do it. hmu if you want to hear the story of the EtOH receptor antagonist and why it never went to market, what with all the dying.

what’s the EtOH receptor antagonist???

okay whew. here we go. there has been a LOT more interest in this than I was expecting (I was expecting none, to be clear), and it has been approx. 8 billion years since I was in undergrad, which is the last time I can reasonably claim to have been CURRENT on Neuro research. (I did my master’s at an institution that does not have what one might call a robust Neuro department and mainly did Stats.) So if a real live Neuro person comes on here and contradicts me, you should probably believe them.

BUT. Here is the story, as I recall it:

Alcohol, or, as we fancy-schmancy-pantsy medical types like to call it to distinguish it from the bajillion other alcohols out there (”alcohol” describes a general type of molecule in chemistry, not the good ol’-fashioned Get You Drunk molecule) ethanol, abbreviated EtOH, is what’s generally called a “sedative-hypnotic.” What that means is that it doesn’t work on opioid receptors, it doesn’t work on cannabinoid receptors. It does stuff to your GABA receptors–GABA being the major inhibitory neurotransmitter–and it also binds to other stuff. We still don’t have its actions in the brain fully mapped. But we know, and we’ve known for a while, that it does stuff to GABA receptors.

A major pharmaceutical company developed an honest-to-God antagonist. If you’re not a pharm person, you may be going, “a what now?” First point: damn near everything your brain does is determined by neurotransmitters and the receptors that love them. Neurotransmitters interact with their receptors in a variety of ways, with a HUGE variety of end results. Humans love jamming other chemicals that are not neurotransmitters into their receptors. Why do opioids work? Because they mimic NTs we make ourselves. Why does cannabis get us high? Because it mimics endogenous (”originating inside”, self-made) NTs. Manmade molecules that alter us are hijacking built-in systems. Don’t even get me started on how fucking bananas cool it is that neurons can adapt to neurotransmitter levels, and in a super awesome sci-fi-like variety of ways. Take a Neuro class! Take five! Take seventeen! Most fun I ever had was in a Neuro lab.

So what’s an antagonist? It’s something that, one way or another, makes it so the NT can’t do its thing at the receptor.

The line of thinking went, if we can keep ethanol from doing its thing at the GABA receptor, we can make people sober again. They can drink and then take a pill and be sober. Wouldn’t that be AMAZING? Wouldn’t that be lucrative? These are questions that drug companies think about a LOT.

So they made the chemical! Its name is
Ro15-4513. You can Google it and get a WAY less interesting description of what went down. But how my professor explained it to us is like this:

It works. It’s an ethanol antagonist at the GABA receptor. You take it and it blows the ethanol off the receptor and you’re sober. And… because humans are awful, you get drunk again. You take another pill. You’re sober again. The time that pill is active is less than the time it takes your body to metabolize ethanol, so you’ve still got all that ethanol swishing around in your system waiting to murder you via aspirating your own vomit the hot second it wears off, but by God, you’re sober.

Except, as mentioned, the GABA receptor is not the only place where ethanol does stuff. One of the effects it has, since it’s such a teeny tiny molecule, is fucking with the lipid bilayer that forms the bulk of your cell membrane. If you’re a Neuro person, you’re getting cold chills right about now, because the only reason neurotransmission works is the properties of the lipid bilayer. You have to be able to transmit electricity down the axon of the neuron to generate an action potential. The lipid bilayer is what allows you to do that.

The pill does nothing for that. So if you take enough of the pill, and keep drinking, there comes a point where you’ve fucked the lipid bilayer beyond repair. You can’t transmit messages. Your brain doesn’t remember how to tell your body to do things like breathe, or not have seizures. And you die!

So, in summary, we have a pill that could make you a responsible designated driver, but actually fucking kills you because people have no self-control.

Moral of the story: Neuroscience Is Super Fun!!!!! It was my gateway drug into medicine. I would never have gone to medical school if it weren’t for my Behavioral Neuroscience professors.

From Twitter.

is it weird that as i got through the tweet my understanding of it lessens?

If you had a recent ancestor who went through starvation it actually altered their genetics and may have passed down genes to you that make you hold on to fat. So this tweet is more accurate than you’d think.

More on that.

Seriously, my body is expecting the next ice age.

OH MY FUCKING GOD.

MY FUCKING GREAT GRANDFATHER LITERALLY FLED LEBANON DUE TO A FUCKING FAMINE AND MY GRANDMOTHER AND DAD AND I ARE ALL FAT AS FUCKING HELL.

FUCK ME RUNNING I DID NOT KNOW THIS.

…That’s going to apply also to anyone whose recent ancestors voluntarily dieted a lot, isn’t it. Diet culture long-term causes more obesity. Sure, it takes decades to show up, but anything you’d hear today about childhood obesity would reflect that. Exercising is still very good for most people, but trying to lose weight shouldn’t be the goal for most people, because a) it usually doesn’t work very well or it comes back and b) your kids or grandkids could end up with extra wonky metabolisms. (And while fat itself is actually not that much of a problem if you keep your fitness up, it can be hard on your joints. That’s actually the biggest health risk if you’re “small end of fat,” under 40, and active–joint problems.)

THAT MOTHERFUCKING ARTIFICIAL FAMINE THAT’S IT I’M GONNA FIGHT THE ENGLISH 

…. holy shit.

adventuresinchemistry:

I really do believe that at least part of the problem of people distrusting science has to do with how we as scientists portray ourselves.

We have actively created a system where we derive authority from being seen as better/smarter/more competent than everyone else and then when people ask why they should trust us we respond with a very condescending version of ‘because SCIENCE IS FACT’ or something along those lines.

Like, consider how that would feel from the outside? Here are a small group of people who you have never met/interacted with who sequester themselves in impenetrable ~elite institutions that you can’t access and don’t feel party to who then tell you that what they say is fact because they’re smarter and better educated than you. And if you ever try to question them (no matter how reasonable your objections may be/seem to you) they condescendingly pat you on the head and say something like ‘don’t worry we know better. you can’t possibly understand what we do.’

Why the hell would you trust them? 

No one likes being told that they’re not smart enough to understand something, and no one likes feeling excluded from something they’ve essentially been asked to accept sight unseen. 

I don’t really have a solution to this, except some vague notion about working harder to portray scientists as people working a job, rather than geniuses who are above it all. 

And like trying harder to understand where people are coming from when they question science. And remembering that being better educated than most doesn’t make us smarter than most. It just makes us better trained in certain types of thinking.

I just think we need to keep in mind what we are asking of people. Which is to put a whole hell of a lot of faith in us.
