A new theory of brain development

Researchers suggest that cells descend from the same progenitor tend to remain near one another, forming a lineage-based mechanism to convey positional information. This theory could have far-reaching implications for biology and artificial intelligence, potentially solving fundamental mysteries of the mind.

The interplay of nonlinearity and topology--nontrivial eigenmodes coupling induced by nonlinearity

A team of scientists experimentally demonstrated nonlinearity-induced coupling of light into topological edge states using a photonic platform. They developed a general theoretical framework to explain the nonlinear process, revealing that nonlinearity enables energy flow from bulk modes into topological edge modes in linear systems.
