You can't smell metal


Can you actually smell metal?

If metal has no odor and you can't smell it, then what are we smelling?

It turns out that it's mostly a chemical called 1-octen-3-one, which is generated when your skin oils react with metal that you've touched.

I thought this was really interesting, and I decided to try making pure 1-octen-3-one myself and to see what it smelled like.

Could you smell iron man's suit? In this video I test if metal, such as iron, actually has a smell. When you smell metal, are actually smelling the metal or something else? I do an experiment to show you what is happening and then talk about the science behind why we think that metals have a smell, or taste.

How We Smell: The Molecular And Cellular Bases Of Olfaction

Three models for the perception of odor molecules are suggested for the first time by experimental data. These studies illustrate how the nose may smell. Moreover, they suggest additional role(s) for odor receptors within and outside the olfactory system.

An Environmental Nuisance: Odor Concentrated And Transported By Dust

Intensive swine production generates odorous emissions which flow from the buildings housing the animals. High ventilation rates bring in fresh air, remove heat and moisture and enhance pork productivity. Numerous compounds contribute to the uniquely offensive odors from swine facilities, including fatty acids, amines, aromatics and sulfur compounds. Dust particles, which originate predominantly from feces and feed, can adsorb and concentrate odorants in swine facilities.

Ooooh, That Smell! Odors Rise With The Temperature

Your nose doesn't lie - odors intensify in the warm summer months, be they of rotting garbage on the sidewalk or fragrant flowers blooming in a garden.
The combination of heat and humidity allows bacteria to grow faster and smells to travel farther, said Victoria Henshaw, who researches urban smells throughout the world.
The air becomes a smelly soup that we all breathe in, Henshaw said.

I Can't Taste Anything

Adrian Wellock lost his sense of taste. After suffering a cold, he started getting a metallic taste in his mouth, which took his palate with it. These days, he only eats foods that are simple to chew and adds spice and herbs to ratchet up the smell. Find out what it's like when everything, actually tastes like nothing.

I HAVE CORONAVIRUS. what it's like + my weird symptom


Update (April 2020)

With all this fear and stress over the coronavirus / COVID-19 pandemic, I thought I'd share my experience with having the virus to hopefully lower your anxiety over it somewhat. Me and my whole family are currently sick with coronavirus, so I go through how we became sick, the symptoms we're experiencing, and how we're treating them and dealing with it all.

Aside from listening to and following all the guidelines being put out on hand washing, social distancing, and quarantining, my biggest tip right now would be to prioritize your mental health and limit your intake of the news on the pandemic. Get the information you need and then just shut it off.

Stay safe & stay healthy, guys!

Taste & Smell: Crash Course A&P #16

Hank resists the urge to devour a slice of pizza so that he can walk you through the way we experience our major special senses. It all boils down to one thing: sensory cells translating chemical, electromagnetic, and mechanical stimuli into action potentials that our nervous system can make sense of. Today we're focusing on smell (olfaction) and taste (gustation), which are chemical senses that call on chemoreceptors. As usual, we'll begin with a quick look at how these things can go wrong.

Pssst... we made flashcards to help you review the content in this episode! Find them on the free Crash Course App!

Does stainless steel remove garlic smell?

Chief Scientist Carl Nelson asks the question, what works to remove the smell of garlic from your fingers?

Many people say that rubbing your wet hands on stainless steel will remove the smell of garlic. The idea being that the chromium oxide in the stainless steel binds with the sulfur compounds in garlic and thus removes the smell.

What do you think? Does it work for you? Do you have a better way of removing the garlic smell? If so, post your thoughts online with #GarlicTest.

Follow my marine biologist friend Luke Tipple on Instagram-

More info that was promised-
What is likely happening is that the sharks can smell the blood but it's just not in a quantity that is interesting to them especially since they don't love human blood that much (btw, I spoke with a marine biologist and mammal blood is all the same from a chemical marker stand point so cow blood is a suitable substitute for human blood). If I did the experiment again, I would want to test human blood vs. fish blood.

This is the most definitive study done to date in a control lab environment on what is least and most interesting to them: The Biology of Sharks and Rays Peter A. Klimley and Steven Oerding; ISBN-13: 9780226442495. Particularly pages 134-140. Figure 6.7; Table 6.2

Summary: I've always wanted to test if sharks can really smell a single drop of blood in the water from 1 mile away. So I went to the Bahamas in shark infested waters and set up an experiment to get to the bottom of things.
