What do GMOs actually modify?
What ARE GMOs anyway? What did we do before we had them? Genetic engineering in our food supply may seem like Frankensteinian disruption of nature, but from a scientific perspective, many GMOs are surprisingly similar to what came before...in this episode, we explore modifications to the tomato as an example of how these techniques are used in the year 2024.

I knew it was simple when I was a kid and Superman smacked a couple of rocks together to make an explosion.
Vigintium or vivintillium idk
She never explained why you can't smash TWO (or more) Ca-48 atoms into a Californium atom to create, say, an element 138. She did touch upon the possibility of there being conditions conducive to the creation of super heavy elements beyond Earth. I would imagine that in, say, the center of a neutron star-- or, of course, a black hole-- there may be pressures great enough to smash enough nucleons together to make an element with several hundred, or thousands, or heck, millions of protons! I'm sure physicists have thought of something like this for many years now.
im your 1000th subscriber
yay
Isent capturing some asteroids a great idea , now ?...island hopeing?
YOOO NEW ELEMENT BEFORE GTA 6 HOW
erebium
would chromium work as the bullet cuz if it works then we just smash it into americium to get element 119 and if we smash it into curium then we will get element 120
Skibidium
Sesquipedalium?
is the periodic table song cooked?
"Chemists who want to smash their atomic toys together into bigger, cooler toys" is the most accurate name for these researchers
They should name it Fortnitium
If it's number of protons that makes the element, then why people say stuff like: adding ksi minus hyperion to the nitrogen 14's nuclei will turn it into hypercoal 15, as it now have chemical properties of the coal, not nitrogen? Why it's not the charge of the nuclei or its chemical properties that should determine the element, but the number of protons? (I suppose it's not about stability, as scientists are working on things that last like 1.6 x 10^-22 seconds or super unstable isotopes and still call it a thing)
Icocennium.
10:57 I-Isn’t it? Based off the isotope number it should have 126 neutrons, which is the NEXT number in that list
i could have sworn Newtonium existed
the lanthanide row will be more awkward to show soon
Call it newrownium
Clickbait: not news of some new development with a high potential for spitting out 119 and/or 120, just a primer gloss.
Ouch, hard to watch you.
Not even a minute in and I already love this channel. Subbed!
Nucleon sounds like what would be the name of the poison-type beta Umbreon.
bluddy not everything is a pokemon reference😭
As awesome as this is, it is incredibly wasteful and unnecessary, even if we do reach an island of stability what could it provide? Very silly to think it would be useful, even sillier to think it would be affordable or possible to produce in large quantities, even for the richest of people... Absolutely saddening to see this while stupidity reigns supreme worldwide...
FINALLY PERIODIC TABLE IS GONNA UPDATE SOON
hope it's name'll be netherite😊
"-ite" would make it a mineral - a geology term.
Berkeley was before 1999, i blame a specific bulgarian for ruining Berkeley
whatever the name is, there is a 99% change it will end with "ium". maybe we should just call it "iumium"
So “yum yum”?
I feel like we should make a new name (like tantalum) or a classic name (like newtonium)
@@kathvg ee-yoom-ee-yum
I have always put my periodic table with elements 119 and 120 and now there here!
Saturnium goes hard
2:42 Americum? It's Americium!
100% right, my own mispronunciation makes my skin crawl! Thank you for helping to ensure that’s a mistake I NEVER make again!!
Hawktuanium
we now need 16 more elements to finish off the row
Electron orbital numbers are already a pain, I feel bad for the Chemistry students of the near future that will have to memorize the list with 8s tacked onto the end. Anyway, the element should be named with J, G, or Q, which are not on the table yet.
G is on the table many times. Gallium, Germanium just to name a couple
“g” brain fart
@@tezzytezlaalso Gadolinium
I think he means just a "G" on its own... *scratches chin and rubs belly perplexedly*
Jermanium
The new element should be named Element Of Surprise imo
VIBRANIUM
She seems like a female version of Sheldon.
einstenium-253 the most common isotope of element 99 has a halflife of 20 days
Behsten (basically element 119) will be RADIOACTIVE ☢️ and TOXIC and UNSTABLE.
Yeahh, let's spend millions to create another useless element, which has an extremely small half life🎉
I shall likely like this comment
Better than spending BILLIONS on a Military that cannot pass an Audit to save the lives of all it’s personnel

yeah we need more elements
New elements might have unexpected practical uses.
I think it's important to keep in mind, GMOs are used when you're spraying crops with glyphosate or any of those other nasty chemicals. I'd rather not eat GMOs, not because of the genetics, but because of the glyphosate that will leach into my food.
I respect your decision to want to avoid glyphosate or any of those other nasty chemicals. But I need you to recognize that you don't have enough information to do that. This is in two ways. 1) Although a relatively large fraction of the GMO foods are modified to resist being harmed by glyphosate, those are the ONLY GMO foods that increase, in any way, the use of any artificial chemicals. Taken all together, GMO foods overall reduce the use of chemicals. This happens several ways: a) the Bt crops, which let the crop produce its own insecticide (cry proteins, using a gene from Bacillus thuringiensis), which is not a nasty chemical, but an actual nutrient for everything but a lepidopteran larva. b) Virus resistant GMO crops require substantially less spraying of insecticides because viruses usually attack a plant through lesions caused by insects eating the plant. c) Same as (b) but for fungus or bacterial diseases. 2) Glyphosate is not only used for herbicide resistant crops. Another use is to KILL crops like wheat or oats shortly before harvest, so that they can be harvested with less moisture content. And this use results in much higher levels of glyphosate residue than the spraying for herbicide resistant GMOs. I'd like to explain this. The use of glyphosate for the herbicide tolerant GMOs is sprayed to kill weeds, rather than with the purpose of dousing the crop, and the time when a farmer wants to kill weeds is when the crop is small, nowhere near harvest time. So the amount of glyphosate that gets into the plant gets onto a tiny plant, rather than one which has grown to full size*, (so the amount is diluted when the crop subsequently gets larger) and since it is months before harvest, rather than a week, the glyphosate also has more time to break down more before the harvest. This is just the opposite for the moisture control application. The glyphosate is purposely sprayed on the very part of the crop (usually grain) to be eaten, at its full size, and the grain is harvested only a few days after the glyphosate is applied. I am not qualified to give you actual numbers, but I am quite sure that the grain sprayed for moisture control caries a much larger glyphosate content than do the crops sprayed for weed control. And don't miss the fact that herbicide tolerant GMO crops are NEVER sprayed for the moisture control application because, of course, it wouldn't work. * except for alfalfa, which is a perennial crop. 3) There are many other herbicides besides glyphosate. Glyphosate is the most used, because of its use in GMO herbicide tolerant crops. But if enough people decide to avoid GMOs, or if they are restricted from growth, a lot of farmers will switch to using other kinds of herbicides. Are these herbicides better or worse than glyphosate? I don't claim to have the expertise to answer this question, but I am suspicious. The controversy over glyphosate began and continues because groups which are anti-GMO have spread claims about glyphosate for the last thirty years. They have mostly ignored other herbicides. There are many studies in the scientific literature about dangers from other individual herbicides. I can give you an example. Glyphosate is now the most widely used herbicide in the world, but before the GMO Roundup-ready crops existed, the most widely used herbicide was atrazine. And atrazine has many problems. First, it is much more toxic (acute toxicity) than glyphosate, so if a farmer switches from glyphosate back to atrazine, it means several times more toxic stuff released into the environment. Besides that, glyphosate is rather sticky so it doesn't flow freely through soil, but atrazine is not sticky so it quickly makes its way into rivers and into ground water - which is drinking water for many people. Wouldn't it be ironic if protests about GMO food ended up making things worse? I try to follow the anti-GMO controversy, which has now became an anti-glyphosate controversy, and during the last year, a lot of oat cereal companies have been criticized for having glyphosate levels at or near the legal limits for food. Oats are not glyphosate tolerant, so any glyphosate found in oats most likely comes from using glyphosate in the pre-harvest moisture control application. I hope you find this comment helpful.
It's funny because legally, how they arrived at a genetically changed product is more important than the fact that it is.

i want natural stuff not gmo!
GMOs are technically “natural”only genes are played with therefore requiring less pesticides or fertilisers to achieve the same results; bio vegetables and fruits are the only true natural vegetables and fruits, however those are much more expensive for the average human; not to mention that the vegetables and fruits that we know today have been carefully selected throughout our history
I wonder if your definition of natural stuff is the same as mine. Imagine that you are at the supermarket, in the fruit aisle, and there are lots of apples for sale. They all have variety names, like Granny Smith, Honey Crisp, Macintosh, etc. Any apple with a variety name was originally the result of a seed planted to grow a tree that made fruit. But if the seeds that were in those apples were, themselves, planted, you's get completely different kinds of apples, probably not as good. So what do the apple breeders do? First, they select a tree with vigorous roots. They let it grow a few feet high and make a cut in the stem. At the same time, they take a branch from the tree that grew the good apple, make a careful cut and insert the cut branch into the cut stem, and probably bind it so that the cut wooden pieces grow into one another. We've known of thousands of years that this can result in the good-fruit producing stem will eventually produce the same kinds of apples that we likes, and that we gave a variety name. Is that something you would consider natural? This is a tree with two different genomes, one in the root and trunk of the tree, and the other in the branches. There is a name, from mythology, for a creature with two distinct genomes. It can be a centaur (part man, part horse), or a lion with a man's head (the Sphynx). But these are just stories, or carved statues. Does this ever happen in nature? Maybe rarely. If it does happen rarely, does it ever lead to something good and desirable? I doubt it. But it is the way every single tree fruit with a name is grown. If you reply and are interested, I can give you example after example of things that are routine in breeding and that are completely unnatural. And they are probably things you eat and drink without even thinking about it.
i think Leherium should be the name because of Tom Leher, the guy who wrote the Element Song
Lehrer, therefore lehrerium. No capitalization.
Such excellent points :)! I've always thought that the issue is not GMOs themselves, but rather what kinds and for what purpose ^^ it's just another tool, and it can be used for both 'good' and 'bad' ^^ Thank you so much for this <3
