It would definitely be | a win-win scenario. | taneq wrote: | Is this not precisely what fair use is about? | Mirioron wrote: | I see this being downvoted, but images are copyrighted. Using | an image for illustrative purposes is not fair use, is it? | Therefore the articles can't just share the same images. | [deleted] | AnimalMuppet wrote: | Hmm. I could swear that, when I first clicked on it, there was | a picture of several of them, next to a dime.

Anyone else? | Symmetry wrote: | I guess being long and thin they don't violate the square/cube | laws that normally keep bacteria from getting too big given that | they have to use their outer walls rather than mitochondria to | respirate. Still very impressive. | JoeAltmaier wrote: | Some larger bacteria use a water sac inside to push all the | living components close to the surface. So osmosis can feed | them oxygen. I wonder if this one does that? ___________________________________________________________________ (page generated 2022-06-23 23:00 UTC)
