Dewdrops on a spiderweb reveal the physics behind cell structures – Princeton University
The physics at work in the beading of dewdrops on a spiderweb is the same as that which drives the sub-microscopic beading of a protein called TPX2, which is necessary…
As any cook knows, some liquids mix well with each other, but others do not.
For example, when a tablespoon of vinegar is poured into water, a brief stir suffices to thoroughly combine the two liquids. However, a tablespoon of oil poured into water will coalesce into droplets that no amount of stirring can dissolve. The physics that governs the mixing of liquids is not limited to mixing bowls; it also affects the behavior of things inside cells. Its been known for several years that some proteins…
