Question #1

What part of science do you wish to see proven wrong, /science/?

Happy Anonymous day /sci/

Hi, I've been researching Mental Health and Mercury and was wowed at what I found.

I have some data for you: http://pastedown.ctrl-c.us/#vGoZCYdD0bnqqjq0LwKzGEj6CsM.markdown

——————————

ok thats the spiel

reality this is biohacking by evil ass niggers from old and evil space faggot land

>aliens

the fucking article:

vaxx fraud:

>mercury was known to toxic since 500BC + 3 Sources

>its an electric / radio conductor, to short circuit brain axxons

>its gods blood/earthsblood, it literally runs at 7Hz while your cycle speed is 720hz and your brain is probably 70,000 hz

>they put fucking bill gates of windows vista in charge of vaccines 3.2billiion people.

>also the vaccines were given to all those women in the Zika outbreak due to a 2014 law [not in the article]

psychiatry fraud:

>father of american institute of american psychiatry and neurology drove around and gave icepick lobotomies

>since then theyve done a number of horrible bizzare surgeries

>not one cure yet

>100-150 million cases of mental illness in the USA (1/2 to 1/3 the population)

>all maybe caused by the mercury [+ sources that have sources]

>but also they never tested the environment for alien biohacking aka MKUltra

I dont know what to do with this data.

The newspapers wont touch (I literally emailed them and about 15 .gov people)

Maybe you can get your professor to read it?

If not maybe you want to run some /sci/ tests? Maybe cure a mental patient or find the cause… pills are a $10billion/month business, theres money in it

Drop your psych/chem major?? Show some love.

If nothing, consider passing the link to a mental patient somewhere, and say "if this helps you pass it on"

OK fags. /b/tard here.

Prepare to science for me.

Have this nice aluminum cake pan for use as an outdoor kittywater repository.

Started using it in late Spring.

Some months later noticed these smallish pits in the interior.

Does anyone know if this is normal for this type of aluminum exposed constantly to water and much direct sunlight?

If these pits are not the result of "normal", expected oxydation/breakdown, then my thoughts for an explanation would be:

a. Contact with some type of noxious or corrosive particles that blew into the water and settled there (WTF could that be in a residential suburb FFS?).

b. Damage from cosmic rays.

WHAT SAY YOU, /SCIENCE/?

Human evolution has ended.

Humanity is no longer subject to natural selection and the species is not going to change.

sure you might get surface variations, and cultural changes.. Muslims flood into Europe rape the shit out of everyone and the recessive gene for blonde hair disappears from the population.

But the species isn't gong to change all that much.

Consider this:

Eskimos adapted to the Artic by learning how to make Parkas and Igloos. There was no natural selection for them to grow fur because of the human ability to make tools

Take those things away and the Eskimo freezes to death just the same as a Pacific islander would.

And because of sexual selection, even if a successful useful mutation happened it wouldn't get passed on.

An Eskimo is born with blubber and fur, so he can swim in the icy ocean and walk around naked in the snow for hours.

But he is also a repugnant freak that no woman will touch and is driven away from the village. No children for the next step in Eskimo evolution so it's a genetic dead end.

Eskimos transcended environmental pressure as natural selection and they did it without a written language or metal tools.

Particle questions

First question: Can a single, lone proton be considered an unstable hydrogen ion?

Second question: If opposites attract, then, in theory, could a negative ion suck a proton in, thus changing what element it is? This is assuming, of course, that there is only one negative ion and a single proton floating around.

Pick a phase

If you were to get a sinlge molecule of something, water for example, would phase would it be said to be in - solid, liquid gas etc.

THE FAULT IN OUR STARS

Written by

Scott Neustadter & Michael H. Weber

Based on the novel by

John Green

May 1, 2012

FIRST DRAFT

HAZEL GRACE LANCASTER (16) lies in the grass, staring up at

the stars. We're CLOSE ON her FACE and we hear:

HAZEL (V.O.)

You have a choice in this world, I

believe, about how to tell sad

stories.

CUT TO a SERIES OF QUICK IMAGES:

- Hazel and the BOY we will come to know as AUGUSTUS "GUS"

WATERS (17) at an outdoor restaurant in some magical place.

[They look very much like the perfect Hollywood couple.]

HAZEL (V.O.)

On the one hand, you can sugar coat

- the way they do in movies and

romance novels.

- "Perfect" Hazel and "Perfect" Gus sit on a BENCH

overlooking an incredible seascape in some foreign country.

She rests her head on his shoulder.

HAZEL (V.O.)

Where villains are vanquished

and… heroes are born and…

- "Perfect" Hazel and "Perfect" Gus kiss in a dark room.

HAZEL (V.O.)

… beautiful people learn

beautiful lessons…

- "Perfect" Hazel and "Perfect" Gus fall onto a bed together.

They look deep into one another's eyes.

HAZEL (V.O.)

… and nothing is too messed up

that can't be fixed with an apology

and a Peter Gabriel song.

BACK TO Hazel on the grass, still watching the stars. Were

those dreams or were they memories? Still unclear.

HAZEL (V.O.)

I like that way as much as the next

girl, believe me. It's just not the

truth.

Hazel closes her eyes.

HAZEL (V.O.)

This is the truth.

And EVERYTHING GOES BLACK. We HEAR:

HAZEL (V.O.)

Sorry.

FADE IN ON:

2.

INT DOCTOR'S OFFICE - DAY

The real Hazel is no less beautiful than the one we just saw.

HAZEL (V.O.)

Late in the Winter of my 17th

year…

There are, however, some key and obvious differences.

First, you'll notice the OXYGEN TUBE in her nostrils which

help her to breathe.

Second, you'll notice her hair - which we couldn't see in the

grass. It's much shorter than the "Perfect" version, the

result of someone whose head was completely shaved a few

years before.

HAZEL (V.O.)

… my mother decided I was

depressed.

HAZEL

I'm not depressed.

Hazel's legs dangle over the side of an exam table. Her

mother FRANNIE (early 40s, younger than she feels) explains

to the DOCTOR:

FRANNIE

… she eats like a bird. She

barely leaves the house,

HAZEL

I'm not depressed.

FRANNIE

… she reads the same book over

and over…

DOCTOR

She's depressed.

HAZEL

I'm not depressed!

Off her look, CUT TO:

QUICK SEQUENCE, which play over:

HAZEL (V.O.)

The booklets and web sites always

list depression as a side effect of

cancer…

- A SHOPPING MALL. Filled with TEENAGE GIRLS - gossipping,

laughing - being teenage girls, basically. And here's Hazel.

With her Mom. And her oxygen tank. Just another day.

Spirit "science"

Hey /science/, do you want to feel angry? Then watch THIS

Why are the types of gene segments that together code for the variable region of the light and heavy chain named V, J and V, D, J, respectively? I think J is named as such, because it joins V(D) with C. I know that CR1, CDR2 and CDR3 are parts of V, but CDR3 includes the whole D, if the chain is heavy, and J. So, why the names?

Scientific Rigor

Let's explore transsexualism

After seeing people's differing view on transsexualism, I figured it would be interesting to try and explore the scientific literature concerning this phenomenon. Mainly, how it originates (possible causes) and how much is nature vs. nurture, and the current treatment options available and their effectiveness comparatively.

I've only used Google Scholar to find this literature. I also tried excluding older studies since they'll likely be references in newer literature and are likely outdated.

Also worth mentioning that I haven't looked in-depth in any of the studies presented here, so forgive me if I include some bad studies and/or interpret them wrong in the conclusion.

Origin

To start, let's find out approximately how many people are transgender.

>How many people are lesbian, gay, bisexual, and transgender?

https://escholarship.org/uc/item/09h684x2

>[…] an estimated 0.3% of adults are transgender

Now for possible causes.

>Transsexualism: A review of etiology, diagnosis and treatment

http://www.sciencedirect.com/science/article/pii/S0022399998000853

>A first indication of anatomic brain differences between transsexuals and nontranssexuals has been found. Also, certain parental (rearing) factors seem to be associated with transsexualism. Some contradictory findings regarding etiology, psychopathology and success of SRS seem to be related to the fact that certain subtypes of transsexuals follow different developmental routes. The observations that psychotherapy is not helpful in altering a crystallized cross-gender identity and that certain transsexuals do not show severe psychopathology has led clinicians to adopt sex reassignment as a treatment option. In many countries, transsexuals are now treated according to the Standards of Care of the Harry Benjamin International Gender Dysphoria Association, a professional organization in the field of transsexualism. Research on postoperative functioning of transsexuals does not allow for unequivocal conclusions, but there is little doubt that sex reassignment substantially alleviates the suffering of transsexuals. However, SRS is no panacea. Psychotherapy may be needed to help transsexuals in adapting to the new situation or in dealing with issues that could not be addressed before treatment.

>The endocrinology of transsexualism: A review and commentary

http://www.sciencedirect.com/science/article/pii/0306453090900417

>Testicular hormones play a decisive role in the sexual differentiation of the genitalia. There is now also an impressive body of knowledge, gathered predominantly from laboratory animals, of the influence of gonadal steroid hormones on the prenatal/perinatal sexual differentiation of the brain. The well-documented mechanisms in animals have been extrapolated, sometimes dogmatically, to the development of sexual orientation and gender identity/role in humans. In principle, it is doubtful that an animal model of human gender identity can be found. Studies in humans have shown that levels of circulating sex steroids and estrogen feedback on luteinizing hormone do not differ between transsexuals and controls.

>Anthropometrical Measurements and Androgen Levels in Males, Females, and Hormonally Untreated Female-To-Male Transsexuals

http://link.springer.com/article/10.1023/A:1024506427497

>Sexual differentiation of the human brain: relevance for gender identity, transsexualism and sexual orientation

http://informahealthcare.com/doi/abs/10.1080/09513590400018231

>[…] observations in human subjects with genetic and other disorders show that direct effects of testosterone on the developing fetal brain are of major importance for the development of male gender identity and male heterosexual orientation. Solid evidence for the importance of postnatal social factors is lacking. In the human brain, structural differences have been described that seem to be related to gender identity and sexual orientation.

>The microstructure of white matter in male to female transsexuals before cross-sex hormonal treatment. A DTI study

http://www.sciencedirect.com/science/article/pii/S0022395610003250

>Our results show that the white matter microstructure pattern in untreated MtF transsexuals falls halfway between the pattern of male and female controls. The nature of these differences suggests that some fasciculi do not complete the masculinization process in MtF transsexuals during brain development.

Question #2

Hello /science/

Recently, I pondered about the definition of life and the black-and-white thinking associated with it. In school, I learned about the characteristics (ex. reproduction, metabolism, etc.) that need to be there in order to define something as a living system.

Rather than upholding this "it is either alive or not" reasoning, I would like to propose an alternative approach by adding a grey zone. Things can now be sort of alive, based on how many characteristics they have in common with modern cells.

I am interested in your opinions about that point of view.

Life's Code Expanded

"[T]wo groups of scientists are reporting for the first time that two new nucleotides can do the same thing – raising the possibility that entirely new proteins could be created for medical uses.

(…)

Millie M. Georgiadis, Steven A. Benner and colleagues from Indiana and Florida wanted to see if another potential set of letters, "Z" (6-amino-5-nitro-2(1H)-pyridone) and "P" (2-amino-imidazo[1,2-a]-1,3,5-triazin-4(8H)one), would form a helix – and evolve.

The researchers found that multiple Z-P pairs can contribute to a double helix, just as C-G and A-T pairs do, with the same combination of flexibility and rigidity required for natural DNA to function. They also showed that the Z-P pairs integrate well with conventional pairs and that six-letter GACTZP DNA can evolve."

Fungus doom

How scientifically plausible in a book the following scenario:

~2050, global temps are 2 degrees higher

rapidly evolving fungus/mold

humanity threatened by fungus colonizing arable soil and buildings

fungus is non-toxic, but reproduces very fast

humanity last chance is a fungal virus that can work only if the fungus doesn't evolve in specific way

Alright, really stupid question, you can delete this shit if you want.

I consider myself someone who is pretty fucking stupid in many categories. Most of my life all I really cared about was anime, surfing the internet, and videogames. all but 1/4th of what I learned in science class has been all but forgotten. Very basic shit.

But not too long after really questioning religion, I started slowly wondering how the universe works, and I want to start learning this stuff again from square one. Where would be a good place to start?

Question.

When traveling at a subsonic speed during the last one hour of hyper sleep, which vector of the Romulan Nebula will suffer the wrath of the impenetrable quickening? And, for extra points, how many wraths to the nearest molton? Be specific. This is a real question.
