Smelling the Screen Door

 

If you stand close enough to a screen door to touch your nose to the screen, it smells like the street when it first rains; but it has to be an old screen, not a new one. (discovered Mar 1 2024; although I've known this smell my whole life as "the screen door" I never noticed it was the same smell)

I find a reddit post titled "I can smell this screen door," and someone comments "Rainwater, rust and just a hint of bug guts"

How Memory Works for the Navigationally Challenged


If this chart makes sense to you, watch the rest of the video here:
The Uses of Memory in Olfactory Search, Antonio Celani Senior Researcher at ICTP, MaLGa Colloquia series, 20th February 2023 (this screenshot taken at 22min)

He uses a quote from Flatland, come on. The presenter, Antonio Celani, was a researcher for the French National Research Council (CNRS) in 2000 - and in 1999, CNRS had a European Symposium on Olfaction and Cognition.

But in other news:
Neuroscientists find that animals replay incidentally encoded episodic memories
Jan 2024, phys.org

(This breakthrough in neuroscience research expands on a 2018 study that first reported evidence that animals can replay past events)

Researchers gave nine rats a list of odors using many common household spices, like cinnamon and paprika. Then, the rats were given a memory assessment where they were presented with two scents from the previous list. The rats must then choose which scent was the third-to-last scent presented.

placed rats in a radial maze where they were confronted with scented lids covering food. After the rats foraged through the maze, they were presented with the opportunity to report the third-to-last scent, having to draw from memory the previously presented scents.

The rats remembered multiple pieces of putatively unimportant information and later replayed a stream of episodic memories when that information was needed to solve an unexpected problem. The first and only trial run ended with a 100 percent success rate.

"We remember information even though it was seemingly unimportant when it was encountered. When we happen to need that information, we replay the stream of events to identify the information needed to solve our current problem."

Patent Lingo



Childhood fame, it’s official – Play-Doh is the smell of a generation.

Now that the kids who spent their childhood mushing pink putty in their hands have become old enough to run the world, they’re changing the rules of intellectual property to protect their olfactory legacy.

Actually, says here Play-Doh has been around since 1956. But I am curious as to how many 60-year-olds today reminisce about the smell of Play-Doh? Feel free to comment on this. I asked a gentleman of about 50 but he’s from Germany. They had their own Play-Doh he says, and he didn’t recall its smell in the same way.

In the US, Play-Doh was a cultural phenomenon; is that what you would call it? For anyone who did not experience something I will call a standard American childhood, the colored putty probably just smells like putty.

To a trained fragrance designer who also did not experience the standard American childhood, it probably smells like “sweet, slightly musky, vanilla fragrance, with slight overtones of cherry, combined with the smell of a salted, wheat-based dough.” Because that’s what the trademark now says.

To that generation of US kids who played with it, it smells like childhood and fun.

So this is now a trademark, which I should assume is something like being protected under intellectual property or copyright law. This is a big deal then, because we can’t copyright fragrance. Fragrance and Fashion are two art forms that cannot be protected under the same laws that sent Pharrell into the courtroom over Robin Thicke’s Blurred Lines.

In fact, after a quick perusal, it looks like there’s only ten other scents in this category (and the UK only has two). The ironic loophole here for Play-Doh is that a product that serves only the purpose of its scent cannot be protected. Play-Doh is a toy, not a perfume or a candle or a cardboard cutout of an evergreen tree. (In the UK, it’s for rose-scented car tires.)

Verizon stores have their own scent trademarked. One that I really like is this company that makes engine lubricant, and it’s got three different aromas that make your car exhaust smell like a fruit basket (cherry, grape and strawberry to be specific). "Fuel Fragrances" by Manhattan Oil, check it out. I like this one because it leads me to my quick diversion – scented Crayola crayons. What the heck were they thinking? They should’ve taken a page out of Play-Doh’s book. The Doh smells good, but it’s not an edible scent. Sure, they say “cherry overtones” and vanilla, but everything smells like cherry and vanilla, right? It’s just not the same as labeling a brown crayon “Chocolate” and then making it smell like chocolate.

In conclusion, and despite the excitement of this news, I am compelled to express my regret on this one issue: Using words to talk about smells is a joke. I understand that laws are made of words, and so that’s all we have, but this – doesn’t mean much in the world of smells.

I would much rather see it as “the smell of childhood and fun.” But I guess that’s too vague. (“Sweet, slightly musky, vanilla fragrance, with slight overtones of cherry, combined with the smell of a salted, wheat-based dough.”)


Hasbro trademarks Play-doh’s scent: Sweet, slightly musky

Notes
The subject of intellectual property comes up a bit here, so I added some links for your interest:

Post Script
Play-Doh and used Play-Doh do not smell the same. Because it’s sticky, and kids can be gross, and together, that makes Play-Doh, potentially the grossest smelliest thing ever. Kids pat it down on peanut butter and paint-covered surfaces, then on the ground, then on their foreheads… Then they take that entire surface area and squish it upon itself, putting all those microbes that were on the outside, now on the inside, and making more, new outside that can now stick to new microbes, which will be squished back into itself again, and again. It might be the greatest recipe for a germ-bomb ever. Then again, according to this seemingly disruptive news about Leukemia and germs, that might not be a bad thing. Maybe Hasbro has another patent brewing as we speak.
