Scientists at Brown University have designed a "new 3D petri dish that more closely simulates the in vitro environment of real tissue," according to this post from MedGadget. The post notes that this isn't the first attempt at such a thing, but "Brown's researchers believe this is a better and easier to manufacture solution."
GTO normally doesn't report on the likes of petri dishes, but we find this downright exciting after research came out earlier this year showing that there's a significant difference between the gene expression of nerves grown in 2D versus those grown in 3D -- casting doubt on studies of biological systems studied in only two dimensions.
