You may have heard someone’s memory praised with the saying “You have a brain like a sponge.” Well, here’s a twist: a sponge that’s like a brain.
A research team from Tufts University in Boston constructed a functioning 3-D brain model by seeding spongy silk scaffolds with mouse neurons. The researchers’ model was a happy home for cells, since it was a 3-D, layered environment that mimicked the structure of the real thing.
It also functioned like the real thing. Researchers say their model
