His joke about eating 10,000 cans of baked beans is a good example of how alot of people that complain about a chemical in food or drugs being harmful, tend to ignore the amount of that chemical that needs to be ingested for it to produce harmful effects.
I had a doctor explain to me the difference between treatment and toxicity: dosage. Sadly the vast majority of people think there are good/safe things and bad/toxic things. Everything is toxic in sufficient dosage. Everything is safe in low enough dosage. We need to get this message out there.

@@nenmaster5218 Ok Nen here is a question for you If a disease kills far less than 2% of people infected(mostly elderly and/or sickly) AND the "vaccines" only prevent severe illness should we lock down the entire economy and thereby increase depression/overdoses and long term inflation (which will likely cause more people to go hungry and or homeless)
The dog sled story makes me tear up every time its mentioned. I grew up with balto as one of my favorite movies, and the fact that it was a true story and the incredible journey the relay teams made and saved so many lives just hits me in the feels every time.

“one of the worst pandemics in recent history”
*Cries in 2020*
Hey ya got to admit, Psychology and Sociology definitely saw a few steps foreword this year. There were many opportunities to observe the extremes of human behavior in a politically and biologically turbulent society. All without the need of consent forms! That is normally one of the greatest hurdles to overcome, but not this year. People were belligerently eager to volunteer their inclusion in these observations. I smell many dissertations on the horizon!
I mean 2020 did see the biggest breakthrough in a while for vaccines.
Why do all people think covid-19 is bad go read history before saying that a simple not deadly and non aggressive virus is the worst in history wtf
@@what_you_say-_- I wouldn't say non-deadly or non-aggressive. It's definitely mild for the majority, but it's the people who it's not mild to who need support. I mean, any underlying illness makes you just that much more vulnerable. ANY. I promise you, you know someone with high blood pressure. Does that mean that person will die? Not necessarily, but why risk it? Y'know? Not to mention the health problems it can leave a person with after they recover from it. Just because you no longer have covid, doesn't necessarily mean you'll go back to being as healthy as you were. Some people's bodies can't handle it. Some people have heart troubles from having covid, breathing problems, etc. While you walk around outside, in public, it's impossible to know if the person in front of you in line has a condition that'll make them vulnerable or could kill them if you were to unknowingly give them covid. Maybe you yourself have a problem and dont even know it, many people do. So, in retrospect, it's just better to treat it as and think of it as the black plague 2.0. Cause it's better to be overly cautious than none at all. It's very, most definitely, bad. The worst? No. Bad? Yes.
Lmfao the spanish flu was much worse than covid. Much much worse.
36:00 RIP to all the good boys, including the ones that didn't come back.

I was taught about Dr John Snow at school, but we were also taught about a brewery in Soho, none of their workers died in the cholera outbreak Dr Snow looked at. They were drinking beer, ie boiled water with hops grains and alcohol, which killed the bacteria. It too pointed to a contaminated water supply causing the disease.
I like that they added the fact ferrets can get the flu. When you're a ferret owner and you have the flu you have to stay away from them or they can get sick ☹

I feel it's worth pointing out that the original Great Race of Mercy to this day holds the record for covering the distance. The one time it really counted, they set a record that hasn't been beaten nearly 100 years after it was set and with more than 45 years of Iditarod racing.
@@fkrkf They change out the dogs in today's race, but yes it was a relay race. Still doesn't take away from the achievement.

I'm listening to this while I work, and I just realized how much Michael Aranda's 'teaching voice' reminds me of LeVar Burton's 'teaching voice' on Reading Rainbow. It turns out to be extremely nostalgic. Thank you.
I get all nostalgic when I hear the voice of a now very famous actor. He played a character called Easy Reader on a mid 70s show called the Electric Company, on PBS. "Easy Reader, that's my name. Readin' words: that's my game". Played by none other Morgan Freeman.
Who had a Maths teacher who told them they wouldn't always have a calculator in their pocket?
I had a teacher who said that xD
By sixth grade, 2000, I never heard another teacher that.

Everyone would have thought you are genius.. and in every damn field?!
@@Gam3B0y23r0 True.
well, sometimes you wouldn't … during a maths exam, that's basically it. ¯\_(ツ)_/¯
Thanks for an interesting and informative video. I’m a medical officer at FDA, and especially enjoyed the stories that involved the evolution of our Agency.
Retired registered nurse here... Thank you for your service!!
I always love hearing about John Snow because it reminds me of a day in my middle school science class where we got to basically do what he did. We all got to make a map like his using clues given to us by our teacher. It felt like we were solving a murder mystery. I don't remember if we actually learned about John Snow (we definitely learned about cholera that day), but I remember being so proud when we figured out which water pump was infected.
The story of Balto ALWAYS gives me goosebumps.

My 1st calculator was sold at Sears. It was a scientific calculator, with an LCD display. I got it for my 15th birthday and sold for around $100. All I know was that I promptly tried to forget everything I had learned about using a slide rule. I loved that calculator, it actually got me through the 1st 4 years of college.
I always think about my 5th. grade teacher, when we would ask of we could use a calculator on our tests. "What?! Do you think you will be carrying a calculator around in your pocket all the time when you grow up?"
Wish I could go back and whip out my construction master 5 app, is one of my favorites. Even calculates the tread and rise for stairs to the 1/16". And she would point out the fact I can figure discounts and fractions in my head. Do they still teach kids to do math in their head? I know it impresses the hell out of the kids on my life.
I grew up in the era of microcomputers so I have always had access to calculators but I did have to learn how to use a slide rule and was forced to not use one most of the time because teachers are big smart.
Anyways I must agree that I attempted to dump that useless info from my brain.
Science got me to 2020.
Specifically, science gave us lasers and laser eye surgery cured my nearsightedness. 2020 vision, oh yeah!!!
Science got me to 2020 by finally finding a surgical procedure to fix my broken digestive system the year I was born with it.
Pyloric stenosis didn't have a reliable fix until 1985, coincidentally the year I was born! Now they can treat it medicinally, or with a less invasive surgery. Before 1985 it didn't have a great survival rate.

The sled dog race ring a bell and then it hit me, there's a kids movie about that. Anybody remember Balto?
Ashlee Knowlton as soon as I heard about the dog sleds I knew it was about balto, and I was just waiting to hear his name. My great grandma survived only because of him. She was one of the more sick kids in that village.
Snow Dogs, too
Togo's another one on it and it's amazing. If you're a dog person, it'll leave you bawling in the corner. I highly recommend it.
@@mitchellblake1475 just this video had me tearing up. Such dedication, and such a happy ending. Makes me believe in goodness in the world.
I do! God that movie was great-
20:05 When you have an incorrect theory already popularized like "bad air" it takes more then a better theory to correct it, to unwind the damage. Any new correlations can be easily dismissed by lack of understanding from old correleations.
interestingly, the words "bad air" in French altered to "malaria" as it was thought that disease spread via bad air. Even more odd, the French word for malaria is paludisme, which has nothing to do with bad air!
This is why I always flick the foreheads of people who talk about the peer review process as though it upholds new discoveries after they prove it true. There is numerous instances in the past and present of scientists blatantly ignoring data or details in the studies they are reviewing just so they don't get knocked off of their high horses. Then I flick them again when they say "well that was then". Human understanding changes, human behavior does not.
To be fair, new data that suggests an old theory is incorrect does very frequently end up to be explanable with the old theory. For example, irregularities in the orbit of Uranus could have (and was, by some) been taken to imply that Newtonian motion was incorrect or incomplete but actually there was just another planet that wasn't accounted for. It's healthy for there to be some inertia to throwing out an established theory.
@@clayxros576 Who the hell goes around flicking scientists for being too sure of themselves? Gotta love these armchair "more-ethical+logical-in-the-light-of-centuries-passed-even-though-I-wasn't-there-to-see-how-it-all-went-down" historical revisionist pundits that think they woulda had the sense+wisdom to do things any differently. You know you're a major gold digger, and what you're really talkin' about is booger flickin' and none of these serious career experimentalists would've allowed your judgemental nose and fingers anywhere within range...
Time will make fools of all of us as well, so don't pretend you're immune to the ravages of progress and the fools it makes of those who don't get it right the first or millionth time, or whatever the surplus of educated yet largely useless dickheads may happen to be like a century or two from now. Oh, to have too much free time on your hands and no direction or purpose. What a glorious time we live in, all the science has been perfected + we live in a utopia that affords us the time- as a way to pass the time- to ridicule those who came before that actually gave it a shot. What a buncha goofs.
Yes, I'm fully conscious of the fact that I too am being judgmental and wasting time and brain cells and oxygen. But you started it. Quick flicking people, whether in reality, or in your scientist policeman imagination, or just for target practice. I thought we'd evolved beyond that sort of behavior.
@@eYeZiQ
I mean, you're the nose gold digger if you think the science is perfected or people have moved on from the older less than ethical methods. Not sure you even read my comment either. My statement had nothing to do with policing scientists, I said "people" numerous times. I flick the forehead of "people" who think everything is perfected and above mistakes or bias. Oh, as a matter of fact.
*Flick*
I was way too young when I watched the movie Balto. Story always makes me cry.
It's thought that the story of the pied Piper was a dypetheria outbreak, essentially they explain the mass deaths as the children being taken. And when you think about a contagious disease that primarily impacts children. It's easier to say someone took them instead of the truth of remembering so many dead children. The mind does things to cope, rewriting history is one of those ways.

As a TI-83 stan, they didn’t talk nearly enough about all the amazing functions modern calculators have! The stats tools! The graphing! The built in calc equation solvers!
My calculator certainly got me to 2020 😂
I was a TI-83 user and it is the ONLY reason I passed my AP Statistics class both terms, and college calc, so many kids in those classes failed because they didn't know how to use the functions, really wish that some of the amazing functions on modern calculators were a bit more common knowledge!

I knew that the movie Balto was based on real events, but I didn't realize that the time frame was even close to accurate. Making that trip in just over 5 days in those conditions is just insane. I feel bad for the dogs that died making the journey, but they saved so many lives. I hope all of those teams received recognition for there contribution.

FUN FACT:
In medieval times kings had certain servants called APOTHECARIES, whose sole role and purpose was to taste test plates of food for poison, before said plates were served to the king/queen, to make sure the food was safe for the king to eat.
To become an apothecary one had to go through a long and rigorous *physical training* phase, each day gradually exposing their own body to tiny bit repeated doses of poisons commonly used by criminals trying to poison royalty, so that they would eventually become physically immune to the posons. It was a very long, not to mention EXCRUCIATINGLY PAINFUL ENDEAVOR, BUT SOME PPL WERE SO DEDICATED AND LOYAL TO THEIR KING/QUEEN, THEY WERE WILLING TO GO THROUGH THIS SUFFERING TO BECOME AN EFFECTIVE APOTHECARY.
I think apothecaries would have been perfect candidates to become part of the "poison squad", as they are immune to most poisons and can safely test foods for others who can't
My goodness! I wish my science teacher was half as good at explaining as you guys.

The Nothing to Sneeze section is really fascinating I love how much people improved the scientific processes over time. It's crazy to see how far we've come but the struggle and thoroughness it has taken to arrive where we are today.
Balto💕 is at the natural history museum in Cleveland. I made a point to see him whenever I went. He’s a forever good boy. 🥲🐕

Usually use this among other videos to fall asleep. Just noticed the shirt on the Poison Squad. Hats of good sir
Turns out, it was a pretty big year for science!
I always feel like a loser when thinking how important some people were and are.
I have no doubt you think that BUT, you easily can make a difference locally. Be THAT person that helps Folks, You won't end up with National recognition, but when you finally kick off decades from now, there will be thousands who bless your name and remember your footprint. Just BE the person that helps. It's that simple.
I agree with Kerry, everyone makes a difference. I’m a teacher, I probably won’t be remembered as some huge person with major achievements. But I can enable the others around me to do their best as well, and that’s still providing a very valuable service to society, and my kids will hopefully remember me and what I teach them. Life isn’t just about being remembered. Just be a good person, and the people who matter will remember you.
kerry krishna until the next generation
All these people wanting to make a difference and I’d just sit back in my couch as I toss a water bottle in the recycling bin. Every little bit helps right?

If you enjoyed learning about the Poison Squads and want to delve deeper, I HIGHLY recommend *The Poison Eaters* by Gail Jarrow. It covers this and more, following the development of the Food and Drug Administration. I know that sounds awfully dry, but I hate history and I read through this (pretty short) book in one sitting.

My dad actually has one of those ancient calculators, inherited from my grandfather. He grew up figuring out how to get the calculator to print out basic pictures, likely wasting much paper and ink in the process. I guess it ended up being worth it, because my dad tells me that that experience is what inspired him to become a computer programmer.
He's a casual collector of this really interesting, now obsolete tech, such as monochromatic computer monitors with only green or only amber LCD displays, floppy discs, and the empty husk of a broken rotary phone.
I kinda want to be a time traveler and go back in time, find these circuit designers, and go "Oh, that's nice..." and pop open a modern gaming laptop just to see the expressions on their faces...
Intentionally poisoning people: The laaaaand ooooof theee freeeee.
Having heard of the 'real' John Snow in university, I cannot emphasise enough how important the development of sanitation in major cities was. We all know that numerous people died due to the lack of sewage systems (and there have been roughly 7 major cholera worldwide outbreaks in the last 200 years). Although you might think that cholera infections are not as prevalent anymore it is estimated that each year there are still 1.3 million to 4.0 million cases of cholera, and 21 000 to 143 000 deaths worldwide (would really love to make a video about that)! I really hope that we could raise more awareness for this issue. Feel free to ask me anything about this topic or stem cells (since I am conducting research in this field)!
Odd question then: what did Snow die of?
Ooh! Stem cells! Neat! Any ideas on how likely they will be used in medical therapy: eg. Organ regeneration? I heard it was being investigated but not used in medicine yet.
@@ahumanwithaface1595 Apparently he died after suffering a stroke in 1858 (I just looked it up on Encyclopaedia Britannica).
One of my favourite questions! Many research groups aim to grow tissues from so-called induced pluripotent stem cells (iPSCs). These stem cells are produced from skin cells and could be derived from the patient itself in order to generate transplants which are not rejected by the immune system of the patient (immune cells normally think that tranplants of other people are foreign invaders and try to destroy them). Although it will likely take decades until we might be able to routinely generate tissues and organs from iPSCs which are safe for transplantation there are currently some first clinical trials. One trial (by a company called ViaCyte) aims to generate insulin-secreting beta cells to treat type 1 diabetes patients while a group in Japan tries to restore the sight of elderly people by using nerve cells which have been generated from iPSCs. Let's see how the trials go!
@@Sciencerely Thank you for all the neat info! I hope the trials go well!
Oh God I had autoplay on while cleaning, and apparently I started watching video before, I sneezed and he immediately said "funny you should mention sneezing". That was mildly terrifying .
Must admit that the Balto sled-race every year is not only a great way to remember those that took on the extremely challenging, life-saving mission, but a fantastic way to publicise the vaccination-scheme!

For my high school electronics class, we each had a TI-30 Calculator and it used a 9 volt battery. This was, of course, back in 1982. Yeah I'm old lol.
We were so young
From the title, I thought it was going to be going over significant science from the last year... :p
"Like that phones thats probably in your pocket right now, ro at least withing arms reach."
Micheal, I'm watching this very video on that phone. In my hands.
The Massengill company got into trouble for calling their poisonous medication an elixir when it did not contain ethanol. If they had put ethanol into it maybe it would not have been so toxic. Ethanol is a competitive inhibitor for ethylene glycol. When one of my cats drank some antifreeze the vet put him on an alcohol drip. The poor kitty was hilarious stumbling around due to his intoxication, but he did survive.
I’m sure they probably tried EtOH without success. So many drugs, especially big complex molecules, are notoriously hard to get into solution. In grad school I worked a bit with the anti cancer drug dacarbazine, which was only soluble to ~10mg/mL in citric acid, mannitol, and something else. Resulting pH was 3-4, equivalent to apple cider vinegar and not conducive to cell culture, so I… picked a different drug to study.
Point is, they probably didn’t set out to hurt people-the level of ignorance back then was just beyond belief by current standards.
17:20 "You probably think of Game of thrones."
I think not!
"Or the British guy."
Never mind >_>
That shirt...
Happy new year everyone. Great compilation thanks
Best video ever all you guys took turns and it was long thank you so much
"A few dozen white guys doesn't exactly represent all of america"
Tell that to the US senate
The Supreme Court "let us introduce ourselves"
I never realized how similar calculator is to smart phone, scientific calculator ti-87 to the note 10+ - they prepped us
John Snow has the greatest honour one can be given in England. He has a pub named after him. It's in Soho, about five minutes away from Piccadily Circus tube station.
I had a bottle shop ad pop up as the alcohol story was introduced, I've never been so happy.
“2020 will be a big year in science.” Yessiree. Quickest vaccine yet. Can’t wait to get it.
The next time there's a viral pandemic, those future virologists working on an mRNA vaccine will thank their predecessors from this past year.
The next step will probably be teaching adaptive AI to develop those vaccines. Throw enough computing power at it and they might have a prototype for the first clinical tests in a couple of days after the viral genome gets sequenced.
🤔
@@SimuLord It depends if these vaccines don’t end up being at the forefront of some serious side effects like most of big phamas medicine. I mean they’ve literally broken world records for lawsuits.
Over on the Prokaryote channel EvoShow:
"How Evolution Got Us to 3.770.002.020"
I have no words for this. Thank you so much!
You do know something John Snow. Thank you
Am watching in 2023, where people are eating Borax again, but on purpose this time.
WOW!I learned much faster and clearer about organic chemistry then I did in my biochem class. Thanks Stephen and scischow for that excellent explanation with Thalidomide!
I love this episode. Need a pick-me-up today so Im watching it again.
Well, in December 2020, we definitely have a different perspective...
