Meet Our Nitrogen-Breathing Bacterial Relative

Oxygen is pretty great stuff, but this recently discovered organism couldn’t care less about oxygen. It breathes nitrogen and may offer a window into how the types of cells in OUR bodies may have evolved billions of years ago.

  1. The universe was created/popped into existence 13 billion years ago, earth formed 3 billion years ago and the its atmosphere formed only 450million years ago. Humans have only been around for 200,000 years and it’s taken us this short amount of time to screw everything up.

  2. ok so human cells took things that turned 02 into atp so we could easily make energy, thats convenient and all, but lets complete the cycle, no? Can we put chloroplasts in our dna? lol. Who needs to eat food (for energy) and breathe when we can just drink water and eat light

    also, can we just use mitochondrians to make electricity? we use yeast to make blood

    most technological life forms are endosymbiontic, but theyre also not self assembling or self producing, and they dont voice their needs in a way thats cohesive enough to generate feelings for us, so we regard their complex arrangement of physical goop to be deeply physically different than self assembling and self producing complex arrangements of physical goop. I think it's an artifact of vitalism

  3. We employ denitrifying bacteria in wastewater treatment to reduce nutrient pollution – there we typically call the condition with nitrate but no oxygen "anoxic"

  4. Another video with with scishow being pseudoscientific and clickbaity.. but as always kudos for titilating the interest in science. The notion of witnessing the evolution of a new organelle is particularly fanciful! Regardless of accuracy they are doing a good job promoting interest and conversation.

  5. I can't wait to finish the video I'm mad he's saying nitrogen like N2 gas or something. It's not even the cover photo shows nitrate ions. Nitrates contain nitrogen but they are still packed full of oxygen which I suspected is ultimately where they are getting the energy from. That's not breathing like how we breathe oxygen. It's more like how we breathe co2 that is to say a waste product. I think the title and intro are misleading.

  6. I'm missing something here:
    The bacteria is termed as eukaryote which is said to be there for 200-300 billion years.
    But at the beginning of the video he says eukaryotes evolved 2 billion years ago.🤔

  7. I am not sure of what they are breathing but it is not nitrate. NO3 is a radical that is bonded to another hydrocarbons, radical, or metal ion. HNO3 is nitric acid but NO3 does not exits as a gas or even in a solution without charge. NO3 is bonded to KNO3 to make salt peter the ingredient in gunpowder. So I think there was a misprint or misunderstanding and you intend to say NO or N2O. If nitrate is involved there needs to be a more complete explanation but the term "breath" is whole inappropriate..

  8. Thats not how scientists think eukaryotes formed. Almost certainly it was some symbiosis that began and they evolved to live enmeshed in each other, as we see. An archea didn't just randomly swallow a bacteria and poor eukaryotes, none of the machinery would have worked
