I work in an olfactory laboratory as a sensory scientist, ask me anything

I work in an olfactory laboratory as a sensory scientist, ask me anything.

what is it

Is it true that malls and Disney theme parks use these chemicals and pump out specific scents?

oh perfect, how can i locate the specific source of a smell? are there smell detectives?

my apartment has been pissing me off--i've lived in two in the same complex and there is this awful construction glue type smell coming from something (in both apartments)

i've been in other apartments in this complex and they DO NOT smell like this, so clearly it's something i own.

any hints?

if you can smell a girls pussy above her bellybutton does it mean she is past her experiation date?

Which model system is best and why is it Drosophila?

how can i make my sense of smell better?

how is that we percieve time?

why some drugs make you percieve time slower or faster

nigger what the fuck kind of question is that

I don't have any firsthand experience with it, but from my research it's p true. We've done some theatre related smells, usually just bodged together boxes shooting out essential oils, but it works. For the casinos specifically, there's a company called Aromatech who makes too much fucking money on specialized bottles of magic money-spending scents.

Yup, that's part of what we do. Basically we concentrate the smell using an air pump into a carbon stick and then send that off to a different lab to test that piece of air by heating up the carbon stick to over 9000 degrees. It is v expense.

For your glue problem, could be fucking anything. We've found ceiling tiles that smelled liked rotting fish before, and cardboard that smelled like rotting human, smells do weird shit. Might want some kind of carbon filter to get rid of the smell, it might help depending on the strength and composition. Other than that, or spending literally thousands of dollars on people like us coming out there, you're boned if you can't find it yourself. rip

Yeah probably, though that might be good for your sex life. I don't know what you're in to.

nigga do you think I have a degree in something other than Liberal Arts?

Can't. You can train to be a bit more aware of smells, we actually have courses to help people with that, but there's a pretty low ceiling to be hit with that; doesn't really help ALL that much.

Brains are weird and I can't wait until those questions are actually answered.

Bitch how do you expect to study something as complex as human olfaction if you can't understand it in a fruit fly.

What is your favorite smell?

damn, thanks for the info! time to sell all my shit i guess

When I smell shit, are there tiny shit particles in my nose?
Even if the shit is in another room?

Is it extra bad for you when you fart in bed?

good question!

my father would always tell me i was breathing someone's anal gas when i smelled farts

>implying I study human olfaction

I just conduct the tests, my nigga. If I don't know a thing, I look it up in our giant library or ask my boss. Ends up being a lot cheaper than 2 more years of coll-age.

Real good freshly baked bread is up there, also girls, uhhhh the exhaust from boats and carb'd cars, yeah those are probably the tops ones.

Godspeed.

Maybe, but not always. Of course there might be shit in your nose, but the actual smell comes from the molecular compounds. H2S, for instance, smells like rotten eggs, because sulfur. CH4, aka methane, smells like farts. Anal gas is a fair assessment of what farts in your nose are, though.

tbh I have real bad farts lul. I blame all the McDonald's.

oh man, something about boat exhaust. I guess there are always good memories tied up in that smell.

You are the one that said you were a scientist. And what do you mean it's cheaper than college? Are you working as a tech?

i like jet fuel too

What's the worst thing you've ever smelled in your research?

Fact. My family owns a `*~Private Island~*`, and that's the only boat I was ever on as a youngster.

That was just the hook for the thread to take off, technically my title is Labratory Technician.

As in, it's cheaper to go "Hey boss, what's the Drosophila model?" than spend 10k a year at a university.

Don't think I can actually place that one in my OLFACTORY MEMORY BANKS. Fuck, I am incomplete.

Butyric acid. Smells like death, literally. We've used it in haunted houses before, works real well to make everyone double uncomfortable. Close second is high levels of H2S, like 100ppm, though that one's not as bad cause your nose gets fatigued to it real quick, which is also how it kills you.

Methane is odourless
>OP confirmed retard/troll

Does your sense of smell deteriorate when you get older?

What are smells? Particle, molecules? If so, as the particles/molecules/whatever flies to the ambient, does the material that it is coming from get lighter and will eventually stop smelling or disapear?

O shit I am retarded why did I say such a thing. What the fuck was I thinking of? The stuff they put in natural gas pipes? Shit I have ruined my hard-won reputation.

Only when you get super fuckin' old, like past 80, but even then it's a crapshoot. We have assessors who are in the top 1% who are like 65 or something, but we've also let some go because they got shitty as they got old. On the whole, though, your sense of smells stays pretty well as you age.

Can you smell what The Rock is cooking?

What are the scientific terms for differentiating the odor of different farts? Is it like with wine?

Even if I used the lab equipment, no.

are those air purifiers with carbon filters legit?

I do eat and smoke in my room alot so am thinking either that or air out the room often.

also, simply, how do they work if they do?

how do you get rid of dead person reek? i used to live in an apt where the previous renter an hero'd and it still smelt weird from time to time

Do peoples noses get burned out after a while
in the 'olfactory product' industry?

My dad was able to detect individual compounds within a smell - tuberose
etc. and claimed a perfume company
executive offered to hire him on the spot
during a casual meeting when my dad successfully identified the ingredients in his cologne. Always wondered if he would have burned out his nose after awhile in such a job.

Some people are 'super sniffers'?

Why does lighting a match after you shit nearly erase the shit-stench

I fucked up.

Around the lab it's pretty standard nomenclature, unless we're referring to a particular compound. So like "Yeah it's kind of an airy, biological scent" type shit.

Also it's mercaptans, that's the thing I made a fool out of myself on.

Molecules. Uh, I suppose it would, though that would potentially take thousands of years. The compounds might even decay into more stable molecules before that happens.

Yup, carbon filters are what we use to purify the air in the lab and recalibrate our noses to odorless air. They would defs help you out, though you'll have to change out the carbon every few months. Basically the compounds stick to the carbon cause carbon likes to combine with everything, so they get trapped in the filter. That's how wastewater treatment plants stop from stinking -- thousands and thousands of pounds of carbon. Also chlorine.

Natural gas has an added tracer so you can smell it if it leaks.
Regularly use pure methane in my work, it's odourless.
OP is both an uneducated fool doing drone work for intelligent people and a faggot.
How does it feel knowing you're not even in the acknowledgements section of the actual important work?

oh cool! defs buying one now thanks man

Holy fuck I did not think this thread would actually live for more than 5 minutes.

First off, pretty metal. Second, you don't, or you have a good carbon filter always running with fresh carbon. Dead people smell always stays, at least from what I've heard.

I don't think a nose could ever permanently be fatigued to certain smells, unless some chemical burn damage happened or something. Yeah, generally 99% of people are average, and the rest are either double shit or double good. Not by the most significant margin, but enough to make a difference in our data.

I'd assume it's cause the sulfur in the match immediately fatigues your nose to the shit smell.

I'll give you a 3/10

Anytime, friendo

Why I only breathe in 1 nostril?
Why do I always have runny nose?
The soft bone between my nostril is curved inside (but not outside my face) makes one hole smaller in volume than the other, whys that?

can you stick something so far up your nose, you hit your brain?

he's not a human development expert you nigger

Cause some compounds are easier to detect at high flow rates, others at low flow, so the human evolved to have one in each nostril for both types.

Sinus problems? Try taking some allergy meds, or use a neti pot.

I think I understand this third line, though I am not 100% sure. Probably the same logic as the first answer.

Yup. Has to be really thin tho

biology

humans tend to breath out of primarily one nostril at a time, though that nostril tends to swap throughout the day.

Runny nose might be allergies, really any number of things. Could just be cold out. Cold air makes your nose run.

And the difference in size of your nostrils is normal, basically everyone is slightly lopsided. One hand is likely larger than the other, too, as are your eyes, feet, and ears, among other things. Almost no mammals with bilateral symmetry are perfectly symmetrical.

>Yup. Has to be really thin tho

No, fuck you, don't be retarded. You can see this in any fucking anatomy textbook
there's bone between the nasal cavities and the brain, you cuck.

what does your shit smell like?

I am a mouth breather, tell me something about it.

Yeah, really thin, like a couple microns. Are you joshing me?

I don't want to talk about it.

Mouth breathing dehydrates you faster and makes it harder to recover after you've been doing strenuous activity because the nasal cavity moistens the air before it gets to your lungs

Is there any science behind certain candle scents in certain parts of the house? Besides lavender helping you fall asleep

Maybe, probably not. I'd bank more on what memories one has with a particular scent, as that rush of nostalgia or whatever will probably impact you more than, uh, apple cinnamon. That's one of the most interesting things about smells, imo, that they're very heavily tied to your memories, usually more than other senses

Is it true that the birth control pill triggers women’s olifacfory senses to reverse, as they do when pregnant, so that they find genetically similar potential partners more sexually attractive (as opposed to the opposite) and thus lead to their choosing partners more likely to give them inbred offspring?

Never heard of that, but I wouldn't immediately discount it. Hormones are weird, and they do weird shit to your body, so fucking with them with pills could make that situation happen, I suppose.

Ah well, PhDs in the U.S. for STEM generally we pay for your tuition.

what's a good way to ignore a bad smell? for example chewing gum? (I have a smelly coworker and can't stand the smell)

Ok. What about those pheromone colognes. Do they make one more attractive to people with vaginas?

Oof, yeah that's not happening with the company I work for, we're only a 10 person outfit, not some huge research lab with millions of dollars. I wouldn't want that anyway, college was fun but I'm over it now.

Pic related.

But actually, I think the only way is to tell them they smell bad and to shower more. Masking agents usually don't work too well.

Eh, I'd assume that one is just marketing bullshit. IMO, working out and sweating and making your own pheromones is the only way to get that kind of result, and it's gonna be a small margin of gain. I would think that any pheromones only make your MORE attractive, not attractive from the start. So if you've got a nice jawline and good abs, they'll help you more than, say, Boogie2988.

Yes. Obviously I wasn’t suggesting that if you sprayed pheromone cologne on a dog, a woman would want to fuck the dog.

How do you make a substance that smells like pussy?

Hey man, we're on Sup Forums, I don't know your intentions.

That one's easy, just get some blood (pig's blood works) and dump a bag of nickels into it.

Touché

Is it possible to build machine that replicate smell sensors to the degree that microphones and cameras replicate ears and eyes and if not how long it will take for sience to reach that level of sensitivity and resolution?

How does the scent of genitals work in the brain? Why does sniffing a pussy or a dick make me super horny?

is there objectively a smell that is the worst possible smell for humans?

how do I unlock my sharingan?

I have no doubt it's possible, as it'd just be sensors that determine molecular compounds, but some of those would have to be real good, since some smells can be detected at like, 100 parts per billion. And there'd have to be so many of them, since there's so many smells, compared to light or sound, which is just one medium to record. Then, on the other side, to reproduce the smells, you gotta have a diffuser with a shit ton of chemicals in it to combine and transfer into your face holes. So maybe in like 100 years?

Hormones and pheromones, nigga. Your lizard brain goes "i can make more of me with this, yes let's" and you boner. sniff more dick.

Not really, unless you count real bad chemical smells like chlorine gas. Smell is probably the most objective of common senses.
