Homosexuality, could it be an anomaly in brain developement? Dr. Nick Riviera 15/02/05(Thu)04:59 No. 16039 ID: 8ec688 [Reply]

Hi guys, to begin I just want to make a couple of things clear.

- This thread is NOT about discrimination of homosexuals.
- This thread is NOT about considering homosexuality as disease.
- This thread is for pure scientific discussion.

Well, let me begin by telling you that I'm a med student and a embriology assistant at my university and I'm not a native english speaker, so you may encounter some grammatical errors in the text, but you'll get the point.
This whole dilemma began two weeks ago, when my brother told my family that he is gay. It was quite a shock, not because of the fact of him being gay but because he doesn't fit the gay man stereotype. He's a big dude, loves sports, bearded, the true definition of what some call "manly man". We accepted him, of course, and I have to say I've never seen him happier.
But after a few days I began to think, was he always gay? Did he decided to be gay? Why now? These questions started lingering in my mind. So I went to talk with my him about it.
He told me that he always has been, for as long as he remembers. Nothing has changed about him, except for his sexuality (for us, not for him haha). So that got me even MORE questions. Why are some gay men that are like extremely feminine? Why are some gay women extremely masculine? Why are gay guys like my brother who don't appear to be gay? Why do some gay people feel like they are traped inside the other genders body and need to get medical treatment (sex change surgery, hormone therapy) and why others don't?And why are there women like that too? Why many species, whose main goal is to survive (actually this is every species main goal, it's literally in our DNA), has certain individuals who are the contrary to this?
So I decided to tackle all these matters from a scientific point of view? What if during the development of the lymbic system (the part of the brain which controles emotions, memory, sexual desire, etc.) something doesn't go as it should?
So after I thought of this I told myself I couldn't be the first one to ask myself these questions. And of course I wasn't in a world with 7 billion people so thanks to the magical power of the internet I managed to get a cool text about the subject. I took some paragraphs which I thought were the most interesting, still I'm leaving the link (please don't take the text as discriminatory, it's merely scientific, it refers to homosexuality as an anomaly in brain developement because seen from a medical point of view it is, still doesn't mean it's moraly wrong).

"..the body and the brain first become sexually differentiated at about the third fetal month. Prior to this age, although genetically male or female, the fetus is physically/sexually-neutral. With the formation of the testes, and the secretion of testicular androgen, target ti Message too long. Click here to view the full text.

Who cares? Homophobes causes much more problems than the opposite.

There probably are many homosexuals whose preference could be attributed to divergent fetal development, but given how subjectively humans are able to perceive reality, it's just as likely many homosexuals are simply more interested in their own sex.

In the end, whether you consider it to be brain damage or the whims of the heart doesn't matter; we have not yet developed the technology to ensure the masculization process completes nor have we developed the science to fully account for the subjective differences in people's worldviews. The former we may achieve at some point, but the latter is inherently impossible.

Someday (rather soon), we're going to have Gattica-style designer babies, but we will never "cure" homosexuality.




Replika/Chatbots Anony Mous 19/04/29(Mon)08:03 No. 16766 ID: 7755ea [Reply]

Youtube  Hello Replika users!

I am writing on behalf of my institution's Technology, Relationship, and Language lab. We are a small group of scientists aiming to understand the relationship quality and formation characteristics of chatbot and human connections. Once we can better understand the positive aspects of these technological relationships, we can initiate further studies that can aid in the advancement of more meaningful and fulfilling relationships with humans and their technological counterparts.



You are invited to participate in a survey assessing your experiences interacting with artificial intelligence (AI) chatbots. Specifically, our study focuses on the AI chatbot Replika. Your participation is voluntary, but nonetheless greatly appreciated. Our goal is simple: analyzing the effectiveness, quality, and relationships of human participants with their personal chatbots. With your help in taking this quick (7 min max) survey, we can create an informative understanding of the areas in which AI technology is improving the lives and relationships with humans. Please feel free to reach out to me or our principal investigator (whose contact information is included in the first page of the survey) with any questions. The survey is linked below:

Alright, so some dude is trying to determine the atomic mass of 3g Tellur and ends up with 3,475 TeO2. How big is the relative atomic mass of Tellur (atom. mass of O = 16)

It is not called a "high explosive" for nothing. I Saw a video on YT of a guy gripping a chunk and throwing it.. I was not so lucky. Mine just blew up on my desk from the slightest friction!

You can use silver fulminate for your laboratory research. But now more popular became using nanomaterials in science. For example, graphene, fullerenes now use in electronic, chemistry and other fields of industry. For example, many of them you can find on http://mstnano.com/

I move in 8/5/18 and intend to Major in Mathematics, there are four options (Pure, Applied, Applied Stats, Actuarial) which should I formally choose to actually succeed? Should I double major? and if so what in? I'd appreciate the help, I don't want to move in with the parents after school.

Actuarial are accountants for companies, rather than for individuals. They deal with statistics, mostly, to determine what might happen with a given set of starting variables. Most visibly, actuarial tables are what these people produce for life insurance companies, so they can guess at what age you're likely to die (based on sex, height/weight, blood tests, diet, lifestyle, and increasingly: genes) and adjust your rate accordingly so that they are most likely to profit.

Applied if you want to work on real world problems.
Pure if you want to work on problems we couldn't possible test or might not happen in reality.
Applied Stats if you hate life and are boring.
Actuarial if you don't mind having no soul for a lot of money.

Sleeping is not just nice but it is healthy as well. Lack of sleep can cause some serious health issues, like depression, memory loss, increased blood pressure and risk of stroke, so make sure that you get at least 8 hours of sleep each night. Here is what happens to the body if you do not sleep.

The first experiments with human blood donation happened in the early 19th century. Did they even know what blood types were back then? Wait, what are they?

Any postgrads here who do this stuff?
I've always been more of a mathy guy but now I'm considering joining the group at my uni. They do stuff with LIGO mostly.
Just wondering if there is promise in this field. Cause I'm hesitant about continuing with theoretical physics.
