4k4s15 | How do cells that are touching not fuse together like soap bubbles? | I'm a medical student so I'm aware of a lot of the biochemistry governing cell membranes, but how do cells that are touching not just fuse together? Is it just the fact that the hydrophobic parts of the phospholipids stop any mixing of the two plasma membranes?

a8fqn2 | How does the new air purifier in China work? It’s apparently working incredibly well and is probably a bio-engineering marvel. | I don’t know if many people have seen it but China has recently installed a ‘air purifier’ of sorts, and it is apparently working incredibly well.
