Sharpest view ever of the Andromeda galaxy

This zoomable picture of the Andromeda galaxy has insane detail. It really impressed me with the crazy amount of stars visible once you fully zoom in. And that is just a small section of one galaxy! Made me realise how unfathomable the total amount of stars in the universe really is

Does having fur help or hinder animals like otters/beavers/polar bears when they swim about?
  • I know otters blow bubbles into their fur to isolate themselves, but this also makes them extra buoyant. For the babies this is quite handy (less drowning etc) but for adults idk if it really helps.

    It really depends on the fur texture probably, seals are also coated in fur but streamlined to perfection.

  • How does DNA decide the shape of the body?
  • I'd guess no, the number of digits and limbs is conserved very well across tetrapods (it's in their name after all). Fucking with the amount of limbs will probably lead to some developmental errors in the early embryo.

  • How does DNA decide the shape of the body?
  • I recently had a course in developmental biology and this is what I can remember the best:

    From the moment of fertilization, the egg has a 'polarity', thus a direction like up and down, left and right etc. This can be established by e.g. the entry point of the sperm or protein produced by the mother in one side of the egg. From here on out protein gradients and interactions on cell membranes specify where cells are and thus what kind of tissue they should become

    This early polarity leads to a certain pattern of cell division. An important part of this is the folding in of tissue layers called gastrulation, creating the beginning for the gastrointestinal tract.

    In vertebrates a streak starts to form in the embryo. This is the start of the vertebrae and the neural tube in it. Also blocks of cells called somites start to form. These blocks are very important for all kinds of tissues in the body.

    Hox genes make the cells in somites get an identity like head, arm etc. So in the end Hox genes are probably what you are looking for. If leg Hox genes are expressed where fruitfly normally have antennae, you get this horror:

    Fruitfly with legs instead of antennae

    Do you all have any tips on activities to do yourself, instead of consuming content all the time?

    I'm pretty sick of my content addiction, like watching youtube or netflix all the time. I would rather be spending my time otherwise so figured fun things are the best to start. Do you have tips for fun things to do? Or how I could search for them?

    Some I came up with myself:

    • Learning some magic tricks
    • Learning some origami
    • Thrift shopping

    Everything is welcome!

    Edit: thank you for the huge response!
