And it's bad news. Microplastics cross the blood-brain barrier and enter the brain within just two hours of consumption. ๐
The new study, published in the journal Nanomaterials, involved feeding mice polystyrene nanoparticles and then examining their brains after two and four hours. The polystyrene particles were already within the animal's brains in 2 hours.
Using computer models, the researchers were able to show that the nanoparticles crossed the blood-brain barrier by a previously unknown biological mechanism. Cholesterol molecules on the brain membrane absorbed the particles, which then allowed them to cross into the brain.
A Chinese study from last year also showed that inhaled microplastics quickly end up in the brain. In mice, this caused noticeable behavioural changes and various signs of neurotoxicity, including reduced enzyme function in the brain.
Here's a link to the new study, which is free to read online:
Yesterday I posted a pretty blackpilling study about microplastics getting into the brain -- and quickly. Lots of people in the comments asked for advice about what to do to reduce exposure. Can you detox your body of plastic? Here are my thoughts. ๐
As far as I can ascertain, you can't detox (i.e. deliberately remove) plastic from your body. One thing you should know is that a proportion of the plastic you consume will pass straight through you. Many studies of plastic exposure are based on stool samples.
Just what proportion of the plastic you consume remains in the body is unclear, but there's no doubt that plastic does remain, and it gets into a wide variety of the body's tissues -- lungs, liver, kidneys, brain, placenta, gut.
New utterly spurious study just dropped slandering people doing what people have done to achieve optimal health for the last 200,000 years. Yes, eating meat makes you more likely to be violent towards an "intimate partner". It also makes you "speciesist" and racist. ๐
So the study was actually just an anonymous survey of c.250 undergraduates, who were asked about their animal product consumption, their history of physically and mentally abusing their partners (!?) and their beliefs about their superiority to other animals.
Not only are meat eaters speciesist, but they're also more likely to be racist and homophobic! (Can you see what they're doing here?)
Every civilisation faces its own unique problems concerning fertility. We aren't the first, nor will we be the last, civilisation to contend with a fundamental biological threat to social reproduction. ๐
The modern West, in addition to the changes brought about by the sexual revolution and prosperity (contraception and abortion, women in the workplace, obesity etc.) also faces the terrible threat of exposure to harmful chemicals on a scale hitherto unseen.
Current projections suggest we might be unable to reproduce by natural means as early as 2045. This is often referred to as a "spermageddon" scenario.
Here's a master thread of threads and posts about testosterone. You're sure to find something interesting in here, so make sure you bookmark this. In no particular order. ๐
IS ELECTROMAGNETIC RADIATION KILLING YOUR TESTOSTERONE AND MAKING YOU INFERTILE?
Maybe, according to this new study. ๐งต
The study is a small-scale rat study. Some of the rats were exposed to extremely low-frequency electromagnetic fields (ELF-EMF) for various durations a day (up to four hours) for 52 days.
ELF-EMF are generated by things like power lives, household appliances and computer monitors. It's worth noting that some studies have already suggested negative effects on humans.
As far as I can see, not enough is made of the link between exposure to estrogenic chemicals and the growth of g*nder dysph*ria and tr*nsgenderism. Here, at least, is one clear study showing that fetal phthalate exposure makes young boys have less masculine play preferences. ๐
In the study from 2010 in the International Journal of Andrology, researchers measured prenatal phthalate exposure in pregnant women and then followed up on the children's play preferences over a period of six years, with parental questionnaires.
Boys with the highest exposure to phthalates, especially DEHP and DBP, tended to show lower scores in typical male play (guns etc.) and higher scores in gender-neutral play (puzzles etc.). DEHP is commonly used in food packaging, DBP as a solvent in cosmetics.
