I predict a future where once again porn is the cutting edge with a cutting edge technology. porn + vr + smell

Prediction: Pi-hole gets a double entendre and becomes more useful than ever.

reminds me of the book "ready player one" in which world-builders would insert terrible smells to troll the minority of VR players with a smell-o-vision device

As someone who was born without a sense of smell this is incredibly intriguing to me. I've always wondered if there's gonna be a time in my life where I'd be able to experience *any* kind of smell through some new scientific discovery. And maybe this is it. Could I shoot you guys a message when I make my way down to Caltech to try this out someday? :)

Out of curiosity, does lacking the sense of smell influence your sense of taste? Do some things taste wildly differently to you versus how your friends would describe them? I have a very weak sense of smell that comes and goes (sometimes I get weeks without being able to smell anything other than the strongest scents) and it definitely has an impact on my appetite and how much I enjoy certain foods. I have noticed th…

Genuine question: how would they know if it has always been a certain way?

If they _lost_ their sense of smell, they had something to compare it with.

I'm a little bit skeptical but i dont have any objective argument or experience in the field to justify it. I didn't want to post it, but I was surprised that almost no one in the hn comments had the same feeling. Don't get me wrong, I would love this finding to be replicable, it would be pivotal as what other nerves could we stimulate to change perception (think pain, mental health issues, loss of senses). Also, I w…

>> We reliably produced distinct scents such as a campfire burn or fresh air!

These are exactly the types of smells people report when they get head CT scans (I've experienced it myself). Always thought it was ozone forming but perhaps it's more interesting than that.

I believe that ozone is usually reported as smelling like pansies (the flowers).

I'm also a lot more sensitive about texture and mouth feel than friends and family. I know that my taste of things differs from others substantially and I cannot appreciate any nuances in food. Fine dining for example is just wasted on me. You could for example mix a lot of cinnamon, thyme, cilantro and turmeric in my rice and I wouldn't notice any difference as I just can't taste most spices at all since they seem mostly smell based. This also makes it a lot harder for me to actually pinpoint what I like about certain dishes and dislike about others. It's just a combination of texture and the basic tastes. I imagine someone who lost their sense of smell later in life would find the way I experience food horribly bland, but I don't! I still find great joy in food, just in a simpler way I guess.

Chiming in as a reply to your comment since I had a similar feeling. There's no... institution!? No university or other institution listed. They list author names, which is something. But no institution, no paper, no heritage of research concepts. No citations outside of a few NIH ones not especially specific to their particular experiment. No real meaningful discussion of mechanisms. The domain itself doesn't have anything other than this page. Granted, whatever, there's no rules in this world, do what you want. But so far there's precious little in the traditional signals we typically rely on to distinguish this from misinformation.

This reminds me a bit of the escherian staircase video from 10+ years that went viral. A bunch of college students walking down the stairs, acting amazed when they found themselves back at the top. It was great acting and video editing, but it was fake and all part of, if I recall correctly, an art project.

I don't want to dismiss it outright either, seems cool as hell. But it's remarkable to me that all it takes is a blogpost to get this amount of uncritical acceptance of a demonstration.

Since you never had any sense of smell, would this help you in developing memories about smell ? I am curious on how your brain react to smell sensation when it does not have any memory associated with it.

That's also something I think about when imagining smelling for the first time.

E.g. smelling something rancid for the first time - how strong of a negative reaction will it be compared to others who grew up with this negative association. Would I ever even be able to map most of the smells others have memorized to their origin? I really hope I get to find out someday.
