  1. Very interesting article but I am quite curious as so the actinofibrils act something to make the skin more stronger. but how can they change the shape of the wing. Maybe I am not smart enough to understand some of the terms in the article.
  2. I have heard that pterosaurs can change the shape of their wing membranes... How is this possible? Can Bats do that same like say use wing fibers to control the shape of their membranes

    Hearing and ear size

    Ok but Owls and birds do not have pinnae but they can still hear. Why is that? In fact Owls can hear pretty well. Oilbirds even echolocate!
  4. How much electricity/energy is needed to produce CH4 by directly using a current and just CO2? Can it be done naturally by microbes?

    Hearing and ear size

    Ok thanks for clarifying.

    Hearing and ear size

    Ah I see... But if the animal has no Pinnae[the cartilage] can it still hear well? What if the animals has a Pinnae that the structure of a conch shells.
  7. I am just curious does the size of a ear affect the sensitivity of one's hearing?

    ear size

    Does the size of an animal's ear effect how good it's hearing will be?

    hydrogenosomes

    Ok if they dun breathe oxygen there must some substance like Fe 3+ .etc as a electron donor. Am I asking the right questions?

    hydrogenosomes

    http://www.wired.com/wiredscience/2010/04/anoxic-animals/ So these animals dun breathe?

    hydrogenosomes

    ???:confused: ok here's a diagram I hope someone can verify whether it's a theory or false. I hope this doesn't meant that animals with hydrogenosomes do not breathe?

    hydrogenosomes

    I was just fascinated that we have multi cellular animals that can live with no oxygen. But i am a bit curious about Hydrogenosomes? What are they? Some of the articles are a bit tough for me to understand. Also how is this hydrogenosome allow the organism to make food and how is this in contrast with photosynthesis apart from the absence of light.

    Metal eating bacteria

    I see... sorry if this sounds whimical. I am just curious.... I believe something like this could be going on on Mars. But you can't make acetate in CO2 rather even if you are near a hot spring or volcano?

    Metal eating bacteria

    Thanks a lot. So that means they might eat other organisms for acetate or is there another way to synthesize their own?

    Metal eating bacteria

    I see thanks a lot... so if they breath iron[iII] like say from hemetite. then what do they "eat". And if will they survive in a cave on Mars? If so which part of the food chain will they be? Producers?

    Metal eating bacteria

    Ok sorry so If Shewanella oneidensis breathes Fe[iII] then it comes out as Fe[iI]? But it has to have some other substances right?
  17. Mouse

    Metal eating bacteria

    So the formula is?? Fe+3 +???
  18. Mouse

    Metal eating bacteria

    Then what about iron reducing bacteria? Like Shewanella oneidensis? They are iron reducing those that meant that their waste product is Fe2 or Fe+2?
  19. Mouse

    Metal eating bacteria

    so it's Fe ions not the pure metal?
  20. Mouse

    Metal eating bacteria

    What if it's the pure iron left over from like say the waste products of iron reducing bacteria like Shewanella oneidensis?
  21. Mouse

    Metal eating bacteria

    Ok so it's the Fe by itself or Fe+ ions?
  22. I was wondering do iron eating bacteria eat the metal iron itself or just the compounds.
  23. Just a figment of my wild brain.... Is it possible for a rodent to change its teeth from this to this? to

    Solar Sailing

    I see so a laser propulsion station will be necessary then? How long will it take using solar sailing to get from Earth to Mars?
  25. Mouse

    Solar Sailing

    So that's means the mirrors or sail have to face the sun to get the "wind" to propel it? What happens if say we managed to get as far as Pluto? The ship will be floating in space?
