everything you see on tumblr is biased towards the perspectives of the types of people who post a lot on tumblr. this is essential to remember
You guys rlly don't realise how much knowledge is still not committed to the internet. I find books all the time with stuff that is impossible to find through a search engine- most people do not put their magnum opus research online for free and the more niche a skill is the less likely you are to have people who will leak those books online. (Nevermind all the books written prior to the internet that have knowledge that is not considered "relevant" enough to digitise).
Whenever people say that we r growing up with all the world's knowledge at our fingertips...it's not necessarily true. Is the amount of knowledge online potentially infinite? Yes. Is it all knowledge? No. You will be surprised at the niche things you can discover at a local archive or library.
the cognitive dissonance from people who want the products of modern medicine but get weird about animal research. like im sorry but this is necessary for the survival of the society we currently live in. and the scientists who work on these things are not evil cackling psychopaths. anyone you talk to in animal research has incredibly complex feelings about their work and incredibly complex relationships to the animals in their care. there are regulations and oversight and penalties in place to make the work as humane as possible and scientists are overwhelmingly the ones enforcing and advocating for better care.
@velvetdemon I'm doing a full reply because I want to give this question the time and space it deserves, and I really do appreciate your curiosity about this.
The short answer: It is deeply unethical. There are nowhere near enough willing patients in the world to be able to do this, and it would be criminal to put them through this.
The long answer: The one side of the equation you're focusing on is: how much of a drug is too much, to the point where it will cause negative side effects or even death? And this is crucial to know. But it's not just a matter of finding out the lethal dosage of a heart cholesterol medication, you need to know that it can actually lower the cholesterol of any living thing. There is no way to know this without giving it first to...a living thing.
But beyond this, I need to emphasize: The goal of a drug trial is to effectively cure people who are already suffering from disease, who are living on limited time.
Drug trials don't just happen on any member of the public, they need to happen specifically on people affected by the disease you're trying to treat. There is at any time a very limited and very marginalized population of the world affected by early onset, familial Parkinson's disease. Because you cannot ethically induce disease in a human being, you are working with, speaking with, and helping patients and their families who are hopeful and desperate for a cure.
If you were to jump straight to human trials from petri dishes, not knowing absolutely anything about how the drug functions in a living, breathing animal body, it would look like this:
We didn't know that minute quantities of the drug interact lethally with x, y, z medication that people are commonly also taking. X number of patients have died as a result.
We didn't know that the drug is fatal to people with [common variant] in their genetics. X more patients have died.
We didn't know the drug exacerbates x, y, z chronic illnesses. X number of people have acquired permanent, lifelong disabilities.
We didn't know the best way to deliver the drug, so we tried multiple ways: the people who received it intravenously are now suffering from a painful, costly, and debilitating condition that did not happen with the ingested form.
I could go on, and on, and on.
The vast majority of these problems can be nearly or almost entirely averted by testing other animals first.
These are all people who possibly could have waited for the normal progression from animal testing to human testing and thus received better outcomes. Some people will pass away in the time it takes to get to that point, and that's heartbreaking, and we all wish science could be faster.
But the cost of expediting science could mean a life of profoundly greater suffering or an even shorter life than the one where no intervention happens at all. And at that point, you have completely exhausted your trust, your goodwill, and your patients' hope, after you've failed to do anything or even worsened the lives of people who are already deeply suffering.
hi, i’m an animal research professional. making sure laboratory animals stay alive, healthy, and enriched has been my full-time job for several years now.
animal research is not the mad scientist wild west that PETA wants you to think it is. there are extremely strict federal laws in place to protect the well being of these animals. animal welfare organizations like AAALAC ensure that lab animals are treated with dignity & respect and are given enough specialized care & enrichment to be happy and content in captivity, just like AZA accreditation with zoos.
not a single animal from a zebrafish to a mouse to a dog to a macaque goes unaccounted for. if an animal gets moved to a new cage, paired for breeding, has a procedure performed on it, gives birth, gets sick or injured, dies, etc. it is legally required that this information is recorded and kept on file for the US federal government to access. failing to record & retain this information is very much punishable by US federal law.
let me tell you - if you abuse or kill an animal, even a mouse - you are almost certainly getting both fired & blacklisted from the industry. if you abuse or kill a more ‘advanced’ animal, such as a dog or monkey, you will likely face criminal charges. killing a monkey is as serious and disastrous as a nuclear meltdown. you are expected to reasonably explain every illness, injury, or death of an animal under your care. you must record all of this information. animals that are clearly suffering with low QOL are required to be euthanized according to AVMA guidelines.
research animals are highly expensive. yes, even the "lesser" animals like mice. the cheapest mice will run you a few hundred $ per individual, with some of the most expensive mice i've cared for being $25,000 per individual. in research we have the "three Rs" - reduction (reduce amount of necessary animals to a minimum), refinement (refine processes to ensure research is accurate and animals feel no pain or distress), and replacement (replace animals with non-living research models as they become available). i can assure you no proper research team is wasting animals (*do not* say "b-b-but elon musk--" his research team is actively being investigated for animal abuse by the government).
research methods that do not require live animals are currently being looked into & efforts spearheaded by - you guessed it - the animal research industry itself (notice how the animal rights people are strangely silent & unhelpful when it comes to this?) but current technology is rudimentary and does not compare to live animal models.
some research animal fun facts (US edition):
all species of animals are only allowed to have one single major surgery performed on them in their entire lifetime.
institutions with nonhuman primates must have a behavior program in place (run by knowledgeable primate specialists) to ensure that they are happy and receiving enough daily enrichment and social interaction.
institutions with dogs are required to have physical exercise programs in place. this means every individual dog gets a substantial amount of leashed AND free-roaming exercise daily, including playgroups with other dogs.
a majority of nonhuman primates get to retire to sanctuaries like peaceable primate sanctuary, and almost all dogs get retired and adopted out by organizations like homes for animal heroes. some institutions will also adopt out unneeded young rabbits, guinea pigs, rats, etc.
some strains of mice glow neon green (or orange or blue) under UV light. this is not harmful to them and is commonly seen in cancer research.
so yes, you can rest knowing that laboratory animals are treated with the utmost respect by their caretakers. and you can stop this awful, ignorant talk of human experimentation that will only end in the abuse of nonwhite people, LGBT people, disabled people, indigenous people, and so many others. please just take a look at this wikipedia page if you think “ethical” human experimentation can exist.
If you want to reduce animal testing - or at least, reduce the amount of things we need animals to be tested with - there is some growing traction in regards to mathematical modelling (also known as in silico studies), in vitro studies (i.e. test tubes), and 3D printing of organoids.
At the moment, this is not a substitute for animal testing. Bodies are incredibly complex and interconnected environments that we're still scratching our heads about, and animal testing is in a lot of ways the most efficient and least harmful way of testing things like medications.

a little reminder! by annalaura_art
thinking about anastasia trusova paintings again
CAN ANYONE HEAR ME
She's on tumblr! @atrusovaartist is her!
you have to be careful reading too many things that are good/smart/well-written bc then you encounter something that isnt and you get confused like ? why didnt they just make this good ? were they stupid
alright I've got to do some quick math to explain attitudes towards AI to my boss.
we're looking to create an AI policy, and when we were talking about this, my boss (older millennial) was genuinely shocked to hear that younger people do not (seem) to view AI positively (a la the recent commencement speakers being booed)
please rb for larger sample size!
Question 1/3
What is your age, and do you feel AI is a net positive or net negative in our lives today?
under 18, AI is a net positive
under 18, AI is a net negative
18-29, AI is a net positive
18-29, AI is a net negative
30-45, AI is a net positive
30-45, AI is a net negative
46-60, AI is a net positive
46-60, AI is a net negative
over 60, AI is a net postive
over 60, AI is a net negative
Question 2/3
How often do you visit or interact with museums/archives (whether in person or online)?
Frequently (multiple times per month)
Often (multiple times per year)
Occasionally (a couple times per year)
Rarely (once every couple of years)
Never :(
Question 3/3
If you saw a museum was using AI in exhibits, marketing, research, etc., would you be more or less inclined to visit that museum?
under 18, more inclined
under 18, less inclined
18-29, more inclined
18-29, less inclined
30-45, more inclined
30-45, less inclined
46-60, more inclined
46-60, less inclined
over 60, more inclined
over 60, less inclined
Thank you for helping with this data collection. Please rb for as big a sample as possible!
