Autism research involving monkeys contends with uphill battle

Macaques and marmosets recapitulate the condition’s core traits better than mice can, but funding uncertainty and challenges at primate centers in the United States could make this work difficult to continue.

U.S. national primate research centers face an uncertain future

The facilities were meant to last 100 years. Four decades shy of that mark, amid flatlined funds and mounting political pressure, their directors are trying to find a path forward.

How the pipa frog hunts prey by touch

Each of the frog’s eight fingers branches into 16 ultra-sensitive tips, which together function as a fovea—potentially the first demonstration of this type of sensory structure outside of mammals.

The genome offers a recipe, not a blueprint, for the brain

During brain development, genes set the rules and turn the knobs; self-organization does much of the rest.

When is self-organization a mechanism in brain development?

Retinal waves offer a powerful example of a self-organizing system that can build structure without external guidance. The field would do well to embrace such phenomena more broadly as a type of mechanistic explanation.
