  • For 150 years, scientists believed lichen were defined by a symbiotic relationship between a fungus and algae. Meet the team of researchers who upended this belief in this short film by Andy Johnson, Talia Yuki Moore, Chris A. Johns, and Kate Furby.

    The fungus provides structure and support for the organism, while the algae produces food through photosynthesis. However, researchers recently discovered that certain lichen have an additional fungus in the mix. This threesome was revealed after a team set out to explain what made one type of lichen toxic versus another that was seemingly identical.

    Wait, this left me with so many more questions than answers. I don’t understand the role of this third partner, and is it always the same third partner, or are their more lichen with three partners but they’re different combos? Also, do all lichen have a third partner or just some? And can we go back to why those two lichen were different but genetically the same? Like, wouldn’t the DNA of the third partner show up? If not, why? And did only one of the two versions have that third partner while the other was just a pair, or did they both have the third partner but it was acting differently in the two different groups? … I was psyched to learn more about this but instead I feel like I walked into an episode summary from the 4th season of a tv show I’ve never seen.

      Also, was the first guy a lichen scientist who also takes pics or a photog who became obsessed with lichen? And what exactly was his job on the international lichen study team? Just taking pics? - I mean I’m an artist so I’m not dismissing the importance of good photos, but it made it seem like he became part of the research? But also it seemed like he was called in after the research was done just so he could take the pic?….

      And I guess it’s not just me who is getting this 4 year old video in their feed. WTH, algorithm?
      I’m also annoyed by the “scientists got it wrong” framing. As if dentists or whomever had known better all along? Or that they’d just been writing articles about which lichens are prettiest and hadn’t bothered looking into their makeup or origins? Or that they were clinging to some dogmatic belief and ignoring the evidence?
      From what I recall from reading articles in the past, this discovery wasn’t so simple, the evidence wasn’t at all obvious.

    I remember when ulcers were caused by stress. One day, maybe more, a doctor in Australia figured out that ulcers were caused by bacteria. Well how did Turtle Island doctors react. They refused to believe it for many years. Than they finally accepted it. Some research to develope a medicine and than patients got a treatment that cured the disease. Skeptical attitudes are a good thing. It prevents bad or incorrect assumptions being used too soon before the new therapy is proven effective.

    • @elenalizabeth
      @elenalizabeth 2 года назад

      More so the dr that discovered it was H.Pylori bacteria that caused ulcers and other drs refused to believe him, he drank some H.Pylori bacteria and developed ulcers soon after. They believed him after that.
      Which is also similar to how hand washing was discovered. The dr said “not washing hands between patients is killing them with invisible germs” and the other drs laughed at him. That dr then later died from an infection after another dr operated on him without washing his hands first. Hand washing in chlorine mixed with water started after that.

    • @KevinUchihaOG
      @KevinUchihaOG 2 года назад +14

      so i haven't read about that, but if its been proved that a bacteria causes ulcers that does NOT mean that stress doesnt have a contributing factor. From what i know people who are more stressed are correlated with having ulcers.
      Maybe stress causes that bacteria to increase in population, stress does changes to our hormones and what not that can have an effect on which bacterias are comfortable. etc. So yeah, i dont think that discovery proves that stress is not a factor in ulcers.

    One fungus, one algae was the view they had on lichens? I don't think so as they seem too smart to be stuck in that outdated idea. It has been known for decades that this was not true. For example, the lichen Lobaria pulmonaria has been known for many years to be a partnership of a fungus, a green algae, and a cyanobacteria. And never once did National Geographic mention that the third organism in the horsehair lichens (Bryoria) was a yeast which is also the culprit that makes yellow horsehair lichens toxic.

      Yep, yeasts are a type of fungi but belong the division Basidiomycota while the main fungal partner in this and most other lichens is in the division Ascomycota. The major difference between the two divisions has to do with how spores are formed. There are a few lichens that have a basidio fungus partner but these aren't accepted as "real" lichens by all lichenologists. One, which I was lucky enough to see a few years ago, is Lichenomphalia.

      IF you notice any area where science meets politics, you will find the exact opposite. A complete inability to pivot or adjust narratives to data and a general escalation in the direction of the political. Politics thankfully cannot hold it back forever. But when people have the power to pass false data as real data and the system makes it too difficult to actually run the required tests. There are huge problems.

    Reminds me of the book "Trouble With Lichen" by John Wyndham. The plot concerns a young female biochemist who discovers that a chemical extracted from an unusual strain of lichen can be used to slow down the ageing process, enabling people to live to around 200-300 years. Wyndham speculates how society would deal with this prospect.

    Symbiosis? Always knew this was the critical part of biology. About time we understood the role of this in our lives. When we successfully explain how mitochondria (energy producing engines of each cell), thought to have once been independently living single cell organisms, became so thoroughly incorporated into cell physiology, it will be apparent we have actually learned something. We are interdependent, not independent.

    This is why I valued the teachers I had the last few years of high school. I went to a private school where the teachers were retired college professors. The world and history and all that’s in it was fluid, so we were taught What is today may not be tomorrow as we build upon our knowledge. we can learn about today and yesterday, but forgetting to ask questions, and then seeking answers it turns into a stag pool. Continuing to ask questions, finding the answers can change everything that we thought we had once known. This is why knowledge is fluid. The emphasis on our education, the last few years, at the school, under the total age of college professors, thinking, processing information, and adding to what we already know, whereas what we already know, was taught as a foundation. A foundation is very important because you can’t change what you do not know.

    So I've been curious when hiking in the NW Oregon woods here. I love to take lichen photography too and I'm so captivated by moss, lichen, fungi. So all those are creating a microcosm type ecosystem within the layers of the forest, on fallen and living trees, stumps, rocks, etc. I'd be really interested in hearing a lot about this microcosm of nature because some look like Dr. Seuss came up with them? Some look like old man's beard, or pieces of lettuce, cups, puzzle pieces, trumpets, all types of textures and colors and I feel like there is a vast amount of depth of info that's going on to create how these lichen find ways to find complex forms of expressions while also tying into their surroundings because they live in symbiosis with their environment. I'm just facinated by them. Truly. I am.

It means living with (others or something). When in doubt, ask a greek. Do not assume...
