A material that can shrink to fit around internal organs without crushing them could be used to monitor electrical activity in the body. It contracts to less than half of its initial length when wet, and can conform…
Sphere packing: Tiny balls fit best inside a sausage, physicists confirm
Simulations show microscopic plastic balls within a cell membrane Marín-Aguilar, S., Camerin, F., van der Ham, S. et al. 2023 What is the most space-efficient way to pack tennis balls or oranges? Mathematicians have studied this “sphere-packing” problem for centuries, but surprisingly little attention has been paid to replicating the results in the real world….
