So, if I'm understanding him correctly, they used telescopes to detect rotating phosphine molecules on Venus by the tiny squeaks they emit while rotating, and it's a possible sign of life because it would attract stray dogs.
omg. I had to pause the video at one point. I came back, read this comment since it was at the top, then unpaused it. I had paused it right before he said, "I should say, this model is..."

I am 50 years old and have been for almost 2 years studying chemistry and physics on my own just because I love them. You do the best videos! I enjoy them and learn so much as well. Thank you for doing these wonderful videos.
I wish the Professor a long , healthy and phosphorus life... He's contributed a lot; not only to the scientific community, but also to the rest of us students, amateurs and curious people on RUclips...
Other (esp popsci) channels: "In today's episode of Clickbait!: Here's *cool thing* it totally means *imminent asteroid impact, extraterrestrial life, whatever* Now for some wild speculation! Like, comment and subscribe!" The professor: Here's a general overview of what's being discussed, here's some context to put things in perspective, this is what I find interesting about it. However, it's important to be skeptical about things like this and this is not my field of expertise so I'm not going to speculate.
There are some very popular Doctors (medical and otherwise) who could stand to be reminded that they are not experts outside their field or specialty. By just having a doctorate your statements gain a lot of weight and you can do a lot of harm when you speak outside of your knowledge and then get quoted out of context.
But he does give the opinion that someone is likely to come up with a non-life process to produce phosphine, due to his knowledge of chemistry. Complicated stuff chemistry. The Universe is still surprising us regularly.
I’m one of the few who actually did chemistry with phosphine. We use to use it to make LiiPH2 by reacting it with n-butyl lithium. This reaction was always carried out on weekends, so if there was any problem there weren’t as many people to evacuate from the lab building.
Prof. Poliakoff, been watching you since childhood. Once, when I was 16 years old, a representative from University of Nottingham came to my school to inform us about the university and I asked him if he knew a prof. Poliakoff from the Chemistry department haha. Today, I am in university myself and I realize that there's no chance someone people know every faculty like they did in my tiny school. How childish of me! Hahaha, you were one of the 3 reasons why I ended up in Chemical Engineering and you have no idea how much I love every second of it. Thanks for impacting me at that age, I wish you many more years of health. Lots of love!
Wow, I always hate when I get parasitic turtles on my t-shirts. Now I know how to get rid of them! Excellent background on Phosphine and what it may mean in terms of life on Venus. Thanks!
I cannot express how grateful I am to have you around helping share all the knowledge you've accumulated. Now if we could only get others to share too.. just as selflessly.
Seeing a new Periodic Videos, video in my sub feed maKes me so happy i can't wait to watch it, all these years and you all held my full attention and interest, keep em comin.
In grain silos they often use aluminium phosphide pellets as a fumigant. It's usually sourced from China and it comes in tightly sealed pull-tab cans since the compound will release phosphine gas upon atmospheric contact. Every fall when the silos are empty they will put the cans down and open them then seal up the silos for several weeks. Afterwards they will start up the drying fans for several hours to clear up any residual gases.
amazing work he's spreading knowledge even at such an age where people are not able even to walk, he's just trembling but lovely person great dedication love you sir
I'm just glad in this world filled with trash people, that there's just some wholesome old guy with some crazy hair that wants to help the world and teach people. I love you old science man.
Rats not having the vomiting mechanism is really important in the field of toxicology and allows for easy administration of substances for understanding their oral pharmacology. Really helpful to know that it is an antimony additive that triggers the vomiting sensation in other species. Keep well all!
At 05:46 the internet was won! "I should say this model is difficult to rotate because it squeaks." "Squeak" I bowed my head in appreciation... well it was something, my eye's were tearing up 😂🤣
I remember as a child hearing the story of will-o'-the-wisp, and wondering why it couldn't be seen today, I spent many a hour across the Trent from you night fishing a pond that had a large marsh which bubbled foul-smelling gases, but not I or anyone I knew or talked to ever seen them spontaneously combust.
Venus was 'spat' from Jupiter's head according to many cultures historical record. For many years it traveled around the Sun as a 'comet', also spoken of in recorded history. It eventually ended up in its present orbit.
I have video suggestion. In my chemistry class my teacher talked about Bhopal Disaster and I found it very interesting (and sad at the same time). A video about this tragedy and its chemistry would be very informative and nice. Thanks!
They also mention in the paper that there can be a chemical process that we don't understand or know about. People just like to concentrate on the possibility of it being life, because it's one of the few ways we know about it naturally occuring. So, even without life, it's interesting ^_^
Yeah, I remember in pharmacology the lecturer discussed animal models of disease, and I recall the ferret was used as the model animal for vomiting because it was the smallest animal capable of vomiting. Not sure if that is wholly true, or maybe it's the smallest practical animal for use in such tests, but its a bit of trivia that stayed with me.
“Sick” in common UK usage means “vomit” (noun) as opposed to “ill” (adjective) which is the common US usage. E.g. UK: “Watch your step! There’s a pool of sick (vomit).” vs US: “I’m feeling sick (unwell), I’m staying home.”
libjet True but more often sick refers to vomit, “I feel ill” instead of “I feel sick” is more common when feeling unwell (at least in the greater London area). Your mileage may vary.
My homeland pretty much was made of marches and forests, before irrigation was a thing, now it's mostly forests - 56% of territory and growing. Those marsh lights here are called "māņugunis", which could be translated as "deceiving lights".
The man is brilliant.. he's hilarious. I would love to just sit down in a comfy chair with coffee and a soft blanket and listen to him talk for hours and hours. I mean I'm doing that now but to hear him in person has to be amazing.
my chemistry teacher was demonstrating reaction between white P and NaOH, but the reaction was rather vigorous and we all had to evacuate the chemistry department! P4 + 3NaOH + 3H2O = PH3 + 3NaH2PO2
I used to watch bubbles rise up through the water at Scriber lake in Washington state. It’s an ancient bog lake. I didn’t know there was phosphine in the bubbles.
I used to have to change the phosphine bottles on an ion implanter. It was right down there as one of my least favourite jobs, along with changing phosphorus oxychloride flasks on the furnaces.
This is how you always proceed when you think you may have found alien life. First, you eliminate all other possible explanations. Then you timidly say "it may or may not be alien life".
“This model is difficult to rotate because it squeaks.” Professor Poliakoff may be the best deadpan comic on RUclips.
I was NOT expecting that. I had to pause the video to laugh.
So, if I'm understanding him correctly, they used telescopes to detect rotating phosphine molecules on Venus by the tiny squeaks they emit while rotating, and it's a possible sign of life because it would attract stray dogs.
@ DITTO!
I would pay big money for an 'Airplane! remake with the Professor in Leslie Nielsen's role.

1. RATS CANNOT BE SICK
2. PHOSPHINE MODEL DOES NOT ROTATE EASILY BECAUSE IT SQUEAKS
3. WHEN YOU POKE THE MUD AT THE BOTTOM BUBBLES OF GAS COME OUT
Rats squeak, therefor the Phosphine model contains rats.
Guess I no longer have to watch the video. All the information is right here.

Indeed, would be great loss to education and science.

I'm really glad to hear the Professor on this!
What about Beirut explosion reaction?
Thank you Professor, I could listen to you talk about chemistry all day. Be well.
Another takeaway is that the Professor is getting better at filming himself during the pandemic.

TLDR: There might be life on Venus but it isn't rats
But did they look inside Venus's sewers?
I'm not sure about that...
🤣 Definitely not rats!
Could be pegasi, especially if they're living in the clouds.
Plot twist: They are hyper-intelligent rats that are pumping phosphine into the upper atmosphere so that humans won't go looking for rats on Venus.
Penguins, not rats!
This man would be a fantastic teacher, lecturer at any college anywhere.

Sir, I don't know why haven't I searched such an amazing channel before, amazing knowledge hope you will be with us for more than 25 years
This has been one of the most helpful videos, for me, in understanding the phosphine on Venus reports.
What a level headed explanation and at the same time we learned something about rats.
Easy to follow without being condescending or elementary. Great vid! I'll look into this channel, subbed.
It's amazing how you can give the feeling of both a Manhattan project's physicist and a grand-father with fresh baked cookies at the same time, Sir.
Wow, I always hate when I get parasitic turtles on my t-shirts. Now I know how to get rid of them!
Excellent background on Phosphine and what it may mean in terms of life on Venus. Thanks!
we're owl exterminators!
1:55 Oof. P2H4 error in vid (as PH2H4)
Yeah I thought I saw some weird video issues, thanks for putting it into words that I can now learn about ;)
I was looking for a comment like this to upvote :)
Unfortunately Brady's videos have dropped considerably in quality since the Prof. Moriarty incident and they never recovered.
@@u32_nekomata What incident?
Ironically, the video description contains the sentence "Apologies for the P2H4 typo, which should read PH2H4".
"If you've learned nothing else! from the phosphine on venus, its the fact that, rats, cannot be sick."
Finally!!! a real knowledgable person talks about it! thanks Profr!
"Let's get back to Venus." The professor is an alien, confirmed!
I cannot express how grateful I am to have you around helping share all the knowledge you've accumulated.
Now if we could only get others to share too.. just as selflessly.
Fantastic! And I'm sure many people will remember more because of the neat facts at the end

This channel is old as youtube and it's still popular
This is huge achivment
Clicked for take on the whole Venus debacle, stated for facts about rats, rat poison, uses of the found chemicals, etc. Wonderful video. ❤️
The supernerd me love seeing these videos!
why do you hunt adams?
So is mine. Also, please do not hunt me.
Interesting stuff, professor. I'm glad you chimed in on this recent discovery.
I appreciate that you post videos “periodically”
Check out @bullaki for a detailed explanation on the recent Venus phosphine discovery.
This was the most informative with a bucket full of fun facts...plus the end was hysterical!
So glad to see the prof doing well!
That was a very convoluted way of teaching us a factoid about rats.
Rats? All I took away from this video is that Phosphine squeaks.
Never cut off all that hair, the channel wouldn't be the same. :-)
This hair is the purest metal.
It was all trimmed short when we first started sheltering in place.
He does have to occasionally trim it a little, otherwise Professor would eventually look like a character from _Naked Gun 33 1/3: The Final Insult._
His hair must be fire proof.
Da Prof with da 'Fro, bro. Rulin' da (fume) hood since Periodic Videos started!
Albert Einstein of Chemistry World and Also great RUclipsr.
Thanks Prof!! HOPE YOU ALL THE BEST AND KEEP HEALTHY!!
I am totally entranced. You are an amazing lecturer!
Best explanation I've heard of the ph3/venus.
I'm just glad in this world filled with trash people, that there's just some wholesome old guy with some crazy hair that wants to help the world and teach people. I love you old science man.
Prof. Poliakoff has the greatest hair known to man.
Also, yeah, Venus.
If someone puts hate comment on here, that guy who posted it will be hated.
"Treat others as you would like others to treat you"
Excellent video, Professor.
I really enjoy the professors et als., videos. I’m just a regular guy ,& find most of the subject matter fascinating & enlightening . Cheers!
Doing great olderester. This was explained much better this time around. Keep it up, mate.👌👍
Great to hear the professor’s say on this matter!!
Sir, am in love with your explanation and story board, hats off to you ...!
It is A Blessing to know Your knowledge, time and effort keep uploading Thks
I focus more on astronomy/cosmology, but it was interesting to hear a chemist's perspective on this
I love this channel. I always learn more than what I came for.
I always learn from the professor. Today i learned that the professor's look are becoming very fashionable among many corona lockdown guys.
Liked the video before I pressed skip, now that's rare. Nice one professor!
I love your sense of humor professor.😊
