    Ads are making a comeback on streaming services. Not only Youtube, which is now getting more serious about blocking ad-blockers, but even on paid streaming. Netflix has an ad supported tier, Amazon runs ads for its own stuff (so far)…

    Compare the amount of protein that is in a flu shot (60 micrograms in Fluzone at most) to a typical mAb (~150 mg up to 1 g at most), you can see how much less the vaccine requires

    And with mRNA you get extra amplification from each mRNA being translated multiple times. Then again an mRNA is a lot more massive than its protein product.


  • I see you’re getting downvoted, and I do have to agree that it’s a pretty optimistic take. With traffic even a tenth what reddit gets, the costs would be significant.

    Now it’s true that eg. Wikipedia can handle massive server load on a donation model, but I think the utility from Wikipedia is more obvious and more amenable to attracting donations. I think it’s a good idea to think about palatable monetization options early on, so we can avoid ending up in a situation where the experience has to suddenly get degraded by intrusive ads or whatever.



  • > > Why is the amount of DNA in plants so much lower than in animal tissue? Is this because plant cells are larger? (some plants like wheat have very large genomes, I wonder how that affects it too)

    They are quoting the DNA concentration in g per kg of dry matter.

    Plant cells have cell walls of cellulose, hemicellulose and pectin, which adds some dry weight that is absent in animals.

    In addition, these seeds and tubers etc. we eat tend to be energy storage organs with a whole bunch of starch vs. not very much regular cell mass. It would be the same way if you ground up bone tissue and measured the DNA concentration.

    Are cells lining the intestine replaced frequently? and which population of stem cells do they come from?

    Yes, very frequently. There are stem cells in the crypts between villi of the duodenum, for example.

    Mastodon is substantially more active than Lemmy thus far. It’s a different type of medium to Lemmy, so what you want to use is up to you.

    Personally I use both, but just like I was spending much more time on reddit than twitter, I’d like to spend more time on Lemmy than Mastodon. I have also found Lemmy a little more intuitive to use initially, so it might be worth spending a couple weeks getting used to how the fediverse works before jumping into Mastodon.
